RESUMEN
OBJECTIVES: The study aims to explore the management of two-level cervical disc disease and to compare outcomes of anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), and hybrid surgery (HS). PATIENTS AND METHODS: Between December 2011 and December 2021, a total of 120 patients (76 males, 44 females; mean age: 44.8±8.1 years; range, 18 to 68 years) who were diagnosed as two-level cervical disc disease and underwent anterior cervical surgery were retrospectively analyzed. The patients were randomly divided into three groups as ACDF, CDA, and HS each consisting of 40 patients. The Neck Disability Index (NDI), Visual Analog Scale (VAS), clinical and radiological findings, and range of motion (ROM) data were evaluated. RESULTS: All of the groups showed a significant improvement according to clinical and radiological outcomes (p=0.01). The mean follow-up was 27.5±6.1 months for ACDF, 20.0±4.7 months for CDA, and 21.1±5.0 months for HS, showing consistency in monitoring post-surgery outcomes. The mean postoperative NDI scores were 13.4±5.6, 14.8±5.2 and 15.0±5.5 in the ACDF, CDA and HS groups, respectively (p=0.056). The mean postoperative ROM values were 20.82±5.66, 32.45±11.21 and 27.18±10.89, respectively (p=0.045). CONCLUSION: All three surgical techniques, ACDF, CDA, and HS, are safe and successful in the treatment of two-level cervical disc disease. However, HS and CDA may be more preferable over ACDF attributed to their motion-preserving benefits and effectively combining fusion and motion preservation techniques, with comparable clinical and radiological outcomes.

BACKGROUND: This study aimed to compare the clinical effect of modified anterolateral and traditional acromioplasty in arthroscopic rotator cuff repair. METHODS: The clinical data of 92 patients with total rotator cuff tears admitted to the Department of Joint Surgery of Jinhua Central Hospital from January 2016 to December 2019 were retrospectively analyzed. Among them, 42 patients underwent traditional acromioplasty during arthroscopic rotator cuff repair, and 50 underwent modified anterolateral acromioplasty. Patients were evaluated for preoperative and postoperative shoulder function, pain and critical shoulder angle, and incidence of rotator cuff re-tear at 12 months postoperatively. RESULTS: The preoperative general data of patients in the classic and modified anterolateral acromioplasty groups did not differ significantly (P > 0.05) and were comparable. The UCLA, ASES, and Constant shoulder joint scores were significantly improved in both groups. The VAS score was significantly decreased at 12 months postoperative than preoperative, with a statistically significant difference (P ≤ 0.05). Shoulder function and pain scores did not differ significantly between the two groups at 12 months postoperatively (P > 0.05). The CSA did not differ significantly between preoperative and postoperative 12 months in the traditional acromioplasty group (P > 0.05). However, 12 months postoperative CSA in the modified anterolateral acromioplasty group was significantly smaller than the preoperative CSA, with a statistically significant difference (P ≤ 0.05). The rates of rotator cuff re-tears were 16.67% (7/42) and 4% (2/50) in the two groups at 12 months postoperatively, respectively, with statistically significant differences (P ≤ 0.05). CONCLUSIONS: Traditional and modified anterolateral acromioplasty while treating total rotator cuff tears using arthroscopic rotator cuff repair significantly improves shoulder joint function. However, modified anterolateral acromioplasty significantly reduced the CSA value and decreased the incidence of rotator cuff re-tears.

Interpositional arthroplasty for the treatment of hallux rigidus (HR) involves resection of the diseased joint surface and placement of spacer material within the joint to preserve length at the metatarsophalangeal joint while still allowing for range of motion. The majority of studies available in the literature have focused on capsular interpositional arthroplasty, revealing generally positive outcomes. Other forms of interpositional arthroplasty are less supported by long-term follow-up and large sample sizes. Moreover, there exists substantial heterogeneity in the studies evaluating interpositional arthroplasty. Despite the limitations of the current data, interpositional arthroplasty seems to be a viable treatment option for HR.

First metatarsophalangeal joint (MTPJ) arthroplasty provides hallux rigidus patients with pain relief and preserved motion, offering an alternative to arthrodesis. Recent advancements in implant technology and surgical techniques have broadened treatment options. Although good outcomes have been documented in the literature, concerns persist regarding increased complications, uncertain long-term efficacy, and challenges in managing failed arthroplasties. Addressing bone loss resulting from the procedure further complicates salvage procedures. Larger cohorts and extended studies are necessary to establish efficacy of first MTPJ arthroplasty. Decisions must weigh the trade-offs between pain relief and potential complications, requiring thorough patient-surgeon discussions.

OBJECTIVE: Interposition arthroplasty of the elbow involves the interposition of a fascia lata or dermis autograft or allograft between the distal humerus and the ulna or radius, while preserving the original form of articulation. INDICATIONS: Interposition arthroplasty is indicated for young patients with high functional demands who suffer from end-stage elbow arthritis and associated pain or joint stiffness. CONTRAINDICATIONS: Contraindications include acute or subacute infection, skeletal immaturity, bone loss, deformity, or gross instability. SURGICAL TECHNIQUE: Once the ulnar nerve has been secured, joint access is established via a posterior approach. The radial collateral ligament (RCL) and the common extensor tendon origin (CEO) are detached, while preserving the anconeus muscle and the lateral ulnar collateral ligament (LUCL). Subsequently, a capsular release is required to maintain adequate joint exposure and address the accompanying stiffness. Three to four transosseous drill holes are placed at the level of the distal humerus to secure the graft. After the graft has been positioned successfully within the joint space using two guide sutures, it can be secured to the distal humerus using a horizontal mattress stitch. Finally, the detached tendon and ligament structures are reconstructed. POSTOPERATIVE MANAGEMENT: After initial immobilization, early functional exercise of the elbow is performed in the motion orthosis, avoiding valgus or varus stress. RESULTS: The efficacy of elbow interposition arthroplasty has been demonstrated, particularly for young and active patients with severe inflammatory or post-traumatic osteoarthritis. Despite the results in terms of postoperative function and pain reduction are satisfactory, the current literature reports high complication, subsequent treatment, and revision rates. In the event of interposition arthroplasty failure, revision with another interposition procedure or conversion to endoprosthesis may be considered.

Background: The aim of this study is to compare the surgical and non-operative management of displaced radial head fractures via a network meta-analysis of randomised controlled trials (RCTs). Methods: RCTs comparing management of isolated, displaced radial head fractures in adults were included in our review and statistical analysis. A systematic review of electronic databases (Medline, Embase and Cochrane Library) were screened for comparative RCTs reporting on the management of displaced radial head fractures in August 2021. Two investigators independently reviewed studies for eligibility and an assessment of bias was performed for each study. A Bayesian network meta-analysis of the included RCTs was performed. Results: Five RCTs (326 patients) were included in our meta-analysis. Treatment methods included radial head arthroplasty (RHA), open reduction internal fixation (ORIF) with metal implants (ORIF-M), ORIF with biodegradable implants (ORIF-B) and non-operative management. In our network meta-analysis of 'good' or 'excellent' patient-reported outcome measures (PROMs), RHA was significantly favourable to ORIF-M (OR: 0.04, CrI: 0.0011, 0.87), ORIF-B (OR: 0.1 CrI: 0.00076, 6.37). Nonoperative treatment was not shown to be significantly worse than RHA (OR: 0.01 CrI: 2.5e-0.5, 3.61). Conclusions: This network meta-analysis shows that in displaced radial head fractures, RHA is associated with significantly superior functional PROMs than ORIF-M based on the evidence available. Nonoperative management has not been shown to be significantly worse. Level of Evidence: Level III (Therapeutic).

OBJECTIVE: This study examined clinical outcomes associated with 3 types of noncontiguous cervical surgeries - anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), and hybrid cervical surgery (HCS) - to improve surgeon decision-making. METHODS: A systematic review was performed using PubMed, CINAHL, MEDLINE, and Web of Science from database inception until June 6th, 2023. Inclusion criteria were studies that reported any type of clinical outcome, examined noncontiguous ACDF, noncontiguous CDA, and/or noncontiguous HCS. RESULTS: Ten articles out of 523 articles initially retrieved were included. Patients (n = 388) had a mean age of 52 ± 5.1 years and a mean follow up time of 33 ± 6.0 months. Overall, 119 patients underwent non-contiguous HCS, 65 underwent non-contiguous CDA, and 204 underwent non-contiguous ACDF. There appears to be no clinically meaningful difference in Neck Disability Index (NDI) score, Japanese Orthopedic Association (JOA) score, and improvement in pain based on surgery type. There was a total of 83 complications (21% of cases) with non-contiguous ACDF having a higher absolute rate of dysphagia (20%) as compared to non-contiguous HCS (6.7%) or non-contiguous CDA (6.2%). Non-contiguous ACDF had a higher absolute rate of adjacent segment degeneration (ASD) as a reported complication (6.4%) as compared to non-contiguous HCS (1.7%) and non-contiguous CDA (0.0%). CONCLUSIONS: There may be no clinically meaningful difference in many clinical outcomes for different non-contiguous surgical interventions for non-contiguous cervical degenerative disc disease (CDDD). However, complication rates, such as dysphagia and ASD, appear higher for non-contiguous ACDF as compared to non-contiguous CDA or HCS.

INTRODUCTION: metatarsophalangeal resection arthroplasty is considered a salvage surgical procedure able to improve the quality of life of patients with major forefoot deformities. MATERIAL AND METHODS: a retrospective observational study of 31 patients (36 feet) with major forefoot deformities operated at our institution was performed. Thirty two feet required additional surgery involving the first ray, most of them (72.2%) through MTP joint fusion. The mean follow-up period was 10.3 ± 4.6 years. Most patients were women (87.1%), the mean age was 74.2 ± 11.5 years. RESULTS: at the final follow-up, mean AOFAS score was 77.9 ± 10.2 points and mean MOxFQ score was 18.3 ± 8.3 points. Visual analog scale (VAS) for pain improved significantly from 7.5 ± 1.2 points to 3.4 ± 2.1 points on average. Good clinical results were also reported on ability to put on shoes comfortably. The mean resection arthroplasty spaces at the end of the study were 1.3, 1.8, 2.5 and 4.4 mm, for second to fifth rays, respectively. The mean sizes of remodeling osteophytes at the end of the study were 1.6, 1.4, 1.1 and 0.7 mm, respectively. Significant improvement was also achieved in the hallux valgus angle (HVA) and intermetatarsal angle (IMA) at the end of the study. CONCLUSION: in our experience, metatarsophalangeal resection arthroplasty continues to be a valid choice in patients with major forefoot deformities, with satisfactory long-term clinical and radiographic results.
INTRODUCCIÓN: la artroplastía de resección metatarsofalángica se considera un procedimiento quirúrgico de salvamento capaz de mejorar la calidad de vida de pacientes con deformidades importantes en el antepié. MATERIAL Y MÉTODOS: se realizó un estudio observacional retrospectivo de 31 pacientes (36 pies) con deformidades importantes en el antepié operados en nuestra institución. Treinta y dos pies requirieron cirugía adicional que involucró el primer metatarsiano, la mayoría de ellos (72.2%) a través de la fusión de la articulación metatarsofalángica. El período de seguimiento promedio fue 10.3 ± 4.6 años. La mayoría de los pacientes fueron mujeres (87.1%), con una edad promedio de 74.2 ± 11.5 años. RESULTADOS: en la última visita de seguimiento, la puntuación AOFAS promedio fue de 77.9 ± 10.2 puntos y la puntuación MOxFQ promedio fue de 18.3 ± 8.3 puntos. La escala visual analógica (EVA) para el dolor mejoró significativamente, pasando de 7.5 ± 1.2 puntos a 3.4 ± 2.1 puntos de media. También se constataron buenos resultados clínicos en cuanto a la capacidad de calzarse con comodidad. Los espacios de resección promedio al final del estudio fueron 1.3, 1.8, 2.5 y 4.4 mm para el segundo al quinto radio, respectivamente. Los tamaños promedio de los osteofitos por remodelación al final del estudio fueron de 1.6, 1.4, 1.1 y 0.7 mm, respectivamente. También se logró una mejora significativa en el ángulo de hallux valgus (AHV) y en el ángulo intermetatarsiano (IMA) al final del estudio. CONCLUSIÓN: en nuestra experiencia, la artroplastía de resección metatarsofalángica sigue siendo una opción válida en pacientes con deformidades graves del antepié, con resultados clínicos y radiográficos satisfactorios a largo plazo.

CASE: A 34-year-old man was acutely treated with radial head arthroplasty and central band repair following Essex-Lopresti injury. A 38-year-old man presented with chronic longitudinal instability following failed radial head arthroplasty, which was performed for failed fixation. Treatment with revision radial head arthroplasty and central band reconstruction restored longitudinal stability. CONCLUSION: We have a low threshold to repair the central band in acute Essex-Lopresti injury with sufficient evidence of disruption. Nearly all chronic cases require central band reconstruction to restore longitudinal stability. We do not temporarily pin the DRUJ, and distal ulnar shortening is rarely indicated.

PURPOSE: This study employs both the fragility index (FI) and fragility quotient (FQ) to assess the level of robustness in the cervical disc arthroplasty (CDA) literature. We hypothesize that dichotomous outcomes involving CDA would exhibit statistical vulnerability. METHODS: A PubMed search was conducted to evaluate dichotomous data for randomized controlled trials (RCTs) in CDA literature from 2000 to 2023. The FI of each outcome was calculated through the reversal of a single outcome event until significance was reversed. The FQ was calculated by dividing each fragility index by the study sample size. The interquartile range (IQR) was also calculated for the FI and FQ. RESULTS: Of the 1561 articles screened, 111 met the search criteria, with 35 RCTs evaluating CDA included for analysis. Six hundred and ninety-three outcome events with 130 significant (P < 0.05) outcomes and 563 nonsignificant (P ≥ 0.05) outcomes were identified. The overall FI and FQ for all 693 outcomes were 5 (IQR 3-7) and 0.019 (IQR 0.011-0.043). Fragility analysis of statistically significant outcomes and nonsignificant outcomes both revealed an FI of 5. All of the studies reported loss to follow-up (LTF) data where 65.7% (23) did not report or reported an LTF greater or equal to 5. CONCLUSIONS: The literature regarding CDA RCTs lacks statistical robustness and may misrepresent the conclusions with the sole use of the P value. By implementing the FI and FQ along with the P value, we believe the interpretation and contextualization of the clinical data surrounding CDA will be better understood.

BACKGROUND: The comparative effectiveness of decompression plus lumbar facet arthroplasty versus decompression plus instrumented lumbar spinal fusion in patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis is unknown. METHODS: In this randomized, controlled, Food and Drug Administration Investigational Device Exemption trial, we assigned patients who had single-level lumbar spinal stenosis and grade-I degenerative spondylolisthesis to undergo decompression plus lumbar facet arthroplasty (arthroplasty group) or decompression plus fusion (fusion group). The primary outcome was a predetermined composite clinical success score. Secondary outcomes included the Oswestry Disability Index (ODI), visual analog scale (VAS) back and leg pain, Zurich Claudication Questionnaire (ZCQ), Short Form (SF)-12, radiographic parameters, surgical variables, and complications. RESULTS: A total of 321 adult patients were randomized in a 2:1 fashion, with 219 patients assigned to undergo facet arthroplasty and 102 patients assigned to undergo fusion. Of these, 113 patients (51.6%) in the arthroplasty group and 47 (46.1%) in the fusion group who had either reached 24 months of postoperative follow-up or were deemed early clinical failures were included in the primary outcome analysis. The arthroplasty group had a higher proportion of patients who achieved composite clinical success than did the fusion group (73.5% versus 25.5%; p < 0.001), equating to a between-group difference of 47.9% (95% confidence interval, 33.0% to 62.8%). The arthroplasty group outperformed the fusion group in most patient-reported outcome measures (including the ODI, VAS back pain, and all ZCQ component scores) at 24 months postoperatively. There were no significant differences between groups in surgical variables or complications, except that the fusion group had a higher rate of developing symptomatic adjacent segment degeneration. CONCLUSIONS: Among patients with lumbar spinal stenosis and grade-I degenerative spondylolisthesis, lumbar facet arthroplasty was associated with a higher rate of composite clinical success than fusion was at 24 months postoperatively. LEVEL OF EVIDENCE: Therapeutic Level I . See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Hallux rigidus is a common condition characterised by first metatarsophalangeal joint (MTPJ) degeneration, pain and limited range of motion (ROM). The gold standard surgical treatment is arthrodesis, providing good pain relief, but sacrifices ROM. The Cartiva synthetic cartilage implant (SCI) has been utilised as an interpositional arthroplasty, aiming to reduce pain whilst preserving range of motion. Current evidence for Cartiva SCI is limited. The aim was to evaluate the clinical outcomes of Cartiva SCI compared to arthrodesis undertaken in our centre. METHODS: A retrospective cohort study was conducted, enrolling all adult patients who underwent primary first MTPJ SCI arthroplasty or arthrodesis for the treatment hallux rigidus. The primary outcome was a validated patient-reported outcome measure (PROM), the Manchester-Oxford Foot Questionnaire (MOXFQ). Secondary outcomes included EQ-5D, complication rates, VAS Pain and FAAM (ADL). RESULTS: Between 2017 and 2020 there were 33 cases divided into two groups (17 Cartiva SCI, 16 arthrodesis, mean age 59.0 ± 9.9 years) with a mean follow up of 2.3 years. There was no statistically significant difference in any of the MOXFQ, EQ-5D, VAS Pain or FAAM (ADL) outcome scores between the Arthrodesis and SCI groups (p > 0.05). The mean MOXFQ Index score was 7.2 ± 6.4 for the SCI group and 3.9 ± 5.8 for the Arthrodesis group at final follow up (p = 0.15). Although complications were high in both groups, the overall hallux reoperation rate was 29.4 % in the SCI cohort and 0.0 % for arthrodesis. CONCLUSION: This retrospective comparative study found no significant superiority of Cartiva SCI over arthrodesis in terms of PROMs. Due to the higher rate of further surgical intervention in the SCI cohort, we recommend arthrodesis as the preferred surgical option for hallux rigidus. LEVEL OF EVIDENCE: III.

Since 2018, the number of total joint arthroplasties (TJAs) performed on an outpatient basis has dramatically increased. Both surgeon and anesthesiologist should be aware of the implications for the safety of outpatient TJAs and potential patient risk factors that could alter this safety profile. Although smaller studies suggest that the risk of negative outcomes is equivalent when comparing outpatient and inpatient arthroplasty, larger database analyses suggest that, even when matched for comorbidities, patients undergoing outpatient arthroplasty may be at increased risk of surgical or medical complications. Appropriate patient selection is critical for the success of any outpatient arthroplasty program. Potential exclusion criteria for outpatient TJA may include age greater than 75 years, bleeding disorder, history of deep vein thrombosis, uncontrolled diabetes mellitus, and hypoalbuminemia, among others. Patient optimization before surgery is also warranted. The potential risks of same-day versus next-day discharge have yet to be elicited in a large-scale manner.

BACKGROUND: In-person hand therapy is commonly prescribed for rehabilitation after thumb carpometacarpal (CMC) arthroplasty but may be burdensome to patients because of the need to travel to appointments. Asynchronous, video-assisted home therapy is a method of care in which videos containing instructions and exercises are provided to the patient, without the need for in-person or telemedicine visits. The purpose of the present study was to evaluate the effectiveness of providing video-only therapy (VOT) as compared with scheduled in-person therapy (IPT) after thumb CMC arthroplasty. METHODS: We performed a single-site, prospective, randomized controlled trial of patients undergoing primary thumb CMC arthroplasty without an implant. The study included 50 women and 8 men, with a mean age of 61 years (range, 41 to 83 years). Of these, 96.6% were White, 3.4% were Black, and 13.8% were of Hispanic ethnicity. The primary outcome measure was the Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) score. Subjects in the VOT group were provided with 3 videos of home exercises to perform. Subjects in the control group received standardized IPT with a hand therapist. Improvements in the PROMIS UE score from preoperatively to 12 weeks and 1 year postoperatively were compared. RESULTS: Fifty-eight subjects (29 control, 29 experimental) were included in the analysis at the 12-week time point, and 54 (27 control, 27 experimental) were included in the analysis at the 1-year time point. VOT was noninferior to IPT for the PROMIS UE score at 12 weeks and 1 year postoperatively, with a difference of mean improvement (VOT - IPT) of 1.5 (95% confidence interval [CI], -3.6 to 6.6) and 2.2 (95% CI, -3.0 to 7.3), respectively, both of which were below the minimal clinically important difference (4.1). Patients in the VOT group potentially saved on average 201.3 miles in travel. CONCLUSIONS: VOT was noninferior to IPT for upper extremity function after thumb CMC arthroplasty. Time saved in commutes was considerable for those who did not attend IPT. LEVEL OF EVIDENCE: Therapeutic Level I . See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE: To evaluate the effect of arthroplasty using interpositional cartilage allografts in patients with temporomandibular joint (TMJ) arthrosis. STUDY DESIGN: This retrospective study included patients treated consecutively between 2007 and 2013 using discectomy and interpositional grafting with lyophilized costal cartilage allograft (Tutoplast) sheets. TMJ pain based on the visual analogue scale (VAS), maximal interincisal opening (MIO), joint tenderness to palpation, crepitus from the affected joint, and postoperative complications were assessed. RESULTS: Arthroplasty was performed on 37 joints among 34 patients (28 women; mean age: 54 years); 24 joints underwent simultaneous condyle shaving. At final follow-up (3 [n = 37] or 5 [n = 21] years), we observed reduced mean VAS (from 7.6 to 0.9; P < .001) increased mean MIO (from 32.5 to 41.1 mm; P < .001), number of joints with capsule tenderness (from 30 to 3; P < .001), and percentage of joints with crepitus (from 97% to 75%; P = .008). One joint required reoperation because of interposed cartilage fragmentation. No permanent facial nerve injury or malocclusion occurred after treatment. CONCLUSIONS: Interpositional arthroplasty is a relatively simple, moderately invasive, and effective surgical treatment for TMJ arthrosis with few complications. However, long-term outcomes of this treatment, specifically beyond 3-5 years postoperatively, remain unknown.

Periprosthetic joint infections (PJIs) are one of the most worrying complications orthopedic surgeons could face; thus, methods to prevent them are evolving. Apart from systemic antibiotics, targeted strategies such as local antimicrobial coatings applied to prosthetics have been introduced. This narrative review aims to provide an overview of the main antimicrobial coatings available in arthroplasty orthopedic surgery practice. The search was performed on the PubMed, Web of Science, SCOPUS, and EMBASE databases, focusing on antimicrobial-coated devices used in clinical practice in the arthroplasty world. While silver technology has been widely adopted in the prosthetic oncological field with favorable outcomes, recently, silver associated with hydroxyapatite for cementless fixation, antibiotic-loaded hydrogel coatings, and iodine coatings have all been employed with promising protective results against PJIs. However, challenges persist, with each material having strengths and weaknesses under investigation. Therefore, this narrative review emphasizes that further clinical studies are needed to understand whether antimicrobial coatings can truly revolutionize the field of PJIs.

BACKGROUND AND OBJECTIVES: Cervical disk arthroplasty (CDA) offers the advantage of motion preservation in the treatment of focal cervical pathology. At present, implant sizing is performed using subjective tactile feedback and imaging of trial cages. This study aims to construct interpretable machine learning (IML) models to accurately predict postoperative range of motion (ROM) and identify the optimal implant sizes that maximize ROM in patients undergoing CDA. METHODS: Adult patients who underwent CDA for single-level disease from 2012 to 2020 were identified. Patient demographics, comorbidities, and outcomes were collected, including symptoms, examination findings, subsidence, and reoperation. Affected disk height, healthy rostral disk height, and implant height were collected at sequential time points. Linear regression and IML models, including bagged regression tree, bagged multivariate adaptive regression spline, and k-nearest neighbors, were used to predict ROM change. Model performance was assessed by calculating the root mean square error (RMSE) between predicted and actual changes in ROM in the validation cohort. Variable importance was assessed using RMSE loss. Area under the curve analyses were performed to identify the ideal implant size cutoffs in predicting improved ROM. RESULTS: Forty-seven patients were included. The average RMSE between predicted and actual ROM was 7.6° (range: 5.8-10.1) in the k-nearest neighbors model, 7.8° (range: 6.5-10.0) in the bagged regression tree model, 7.8° (range: 6.2-10.0) in the bagged multivariate adaptive regression spline model, and 15.8° (range: 14.3-17.5°) in a linear regression model. In the highest-performing IML model, graft size was the most important predictor with RMSE loss of 6.2, followed by age (RMSE loss = 5.9) and preoperative caudal disk height (RMSE loss = 5.8). Implant size at 110% of the normal adjacent disk height was the optimal cutoff associated with improved ROM. CONCLUSION: IML models can reliably predict change in ROM after CDA within an average of 7.6 degrees of error. Implants sized comparably with the healthy adjacent disk may maximize ROM.

OBJECTIVE: This retrospective study was designed to evaluate the incidence and predisposing factors of heterotopic ossification (HO) after cervical disc arthroplasty (CDA) with a specific implant at 1 and 2 levels, and to investigate the biomechanical effects related to HO. The study goal was to identify ways to reduce the likelihood of HO formation after surgery. METHODS: The study included patients who underwent only 1- or 2-level CDA with the Baguera C disc between November 2014 and December 2021 at a single medical center. All patients were operated on by the same neurosurgeon. The surgical indication included 1-level or 2-level disc herniation between C3 and C7 with radiculopathy, myelopathy, or both, with minimal spondylosis. The various factors were assessed by evaluating plain radiographs and cervical CT scans. The presence of HO was evaluated at different intervals postsurgery, and HO severity was graded using the McAfee classification. RESULTS: Of 107 patients who underwent CDA, 47 (43.9%) had HO at 63 of 171 levels (36.8%). Most cases with HO were grade 1, and no grade 4 was observed. Statistically significant risk factors for HO were the length of endplate coverage ratio and inferior anterior residual exposed endplate (AREE); sex, age, implant height and width, shell angle, and pre- and postoperative functional spinal unit (FSU) angle were not significant. More AREE and greater kyphotic postoperative FSU angle in the flexion position were significant factors differentiating HO grades 0 and 1 from grades 2 and 3. Furthermore, the non-HO group showed a trend of higher range of motion at any postoperative time compared to the HO group, especially at 1 month after surgery. CONCLUSIONS: The HO incidence after CDA was correlated with the residual length of endplate coverage and inferior AREE. Additionally, the AREE and kyphotic postoperative FSU angle in the flexion position were associated with HO grade progression. Patients with HO also showed a trend of lower range of motion at 1 month after surgery. Using an adequately sized implant and encouraging neck motion may help prevent HO development and progression.

Rhizarthrosis is one of the most common arthritic changes in the hand, which has led to the development of a large number of surgical methods in recent years. In addition to the traditional resection arthroplasty with tendon suspension or interposition, if needed, thumb saddle joint prostheses are being used more and more frequently. However, these are not an option for all patients such as those with severe osteoporosis, severe nickel allergy, insufficient height of the trapezium or STT osteoarthritis. This study examined whether the traditional surgical methods continue to have their "right to exist" or whether they will be replaced by prostheses. In a retrospective study with prospective data collection, 48 hands of 45 patients diagnosed with rhizarthrosis in stages II and III according to Eaton and Littler were clinically examined 2.5 years after resection arthroplasty/resection-suspension-interposition arthroplasty using flexor carpi radialis (FCR) or abductor pollicis longus (APL) tendon strips in the years 2015-2018. The postoperative outcome was assessed using mobility, grip strength, two-point discrimination, postoperative satisfaction with regard to pain and resilience, as well as the DASH and MHQ questionnaires. There were no significant differences in surgery duration, inability to work, time to full weight-bearing, pain, satisfaction, grip strength and mobility. Regardless of the surgical method used, patients achieved an almost free range of motion in the thumb and wrist as well as age-appropriate hand strength. Pain at rest was rare; 48% were pain-free during exercise. The DASH questionnaire scored 20.2, 13.9 and 22.1 points and the MHQ scored 76.3, 79.3 and 79.4 points. Hence, the traditional surgical techniques showed good postoperative results with high patient satisfaction. "Newer procedures" such as endoprosthesis offer promising results in terms of faster regeneration times. However, this is offset by a longer surgery time and higher material costs, which means that resection arthroplasty represents a long-established procedure with a low potential for complications and a lower revision rate and should continue to be used, especially if there are relative contraindications to an endoprosthesis.
