RESUMEN

BACKGROUND: The clinical challenge of unexpected positive intraoperative cultures (UPICs) persists in two-stage resection arthroplasty for managing periprosthetic joint infections (PJIs) following total knee arthroplasty (TKA). This study aimed to investigate the incidence of UPICs during the definitive reimplantation phase of two-stage resection arthroplasty of the knee and to assess both the infection- and revision-free survivorship of the implanted prosthesis. METHODS: This retrospective study included 450 two-stage resection arthroplasties of primary knee prostheses performed between January 2012 and April 2017. Patients were excluded if they: (1) underwent three or more staged resections; (2) had ambiguous clinical documentation or deviated from the two-stage protocol; or (3) underwent revision arthroplasty prior to the PJI. Additionally, patients presumed aseptic before the second-stage reimplantation were excluded if they lacked joint aspiration or met the 2011 Musculoskeletal Infection Society (MSIS) criteria for PJI before implantation. RESULTS: After exclusions, 300 patients were analyzed. Among them, 14% had UPIC during the second-stage reimplantation. The follow-up time was 2,316 (range, 1,888 to 3,737) days and 2,531 (range, 1,947 to 3,349) days for UPIC and negative intraoperative culture (NIC) groups, respectively. Re-revision due to subsequent PJI occurred in 26.2% of UPIC patients and 15.1% of NIC patients. The 2-year infection-free survival rates for the NIC, 1 UPIC, and ≥ 2 UPIC cohorts were 99.5, 98.2, and 94.3%, respectively, while the 5-year survival rates were 92.1, 91.1, and 54.3%, respectively. The unfavorable survivorship was significantly different in multiple UPIC cases (P < 0.001). Multiple UPICs with pathogens consistent with the first-stage findings were strongly associated with the risk of reinfection (P < 0.001). CONCLUSIONS: An UPIC was identified in 14% of second-stage reimplantations. Patients who had multiple UPICs demonstrated truncated survivorship and suboptimal outcomes relative to the NIC and single UPIC cohorts, especially with pathogen consistency to the first-stage surgery.

RESUMEN

This retrospective cohort study aims to investigate the clinical outcomes of Girdlestone resection arthroplasty (GRA) in injection drug users with septic hip arthritis. Patients who underwent primary GRA for septic hip arthritis secondary to injection drug use at two academic trauma centers from 2015 to 2023 were retrospectively reviewed. Patient demographics, surgical details, and follow-up outcomes, including patient-reported outcome measures, were collected and analyzed. The cohort included 15 patients, with a mean age of 44 ± 11 years and a mean follow-up period of 25 ± 20 months. Among the 15 patients, overall mortality was 27%, and only 4 patients underwent total hip arthroplasty (THA) following GRA. Infection resolution rates were significantly higher in patients who received an antibiotic spacer (75% vs. 0%, p = 0.048). GRA in injection drug users is associated with high mortality and low conversion rates to THA. The use of an antibiotic spacer during GRA significantly improves infection resolution rates. Larger studies are required to determine the optimal management strategies for this patient population.

RESUMEN

BACKGROUND: Megaprostheses were first employed in oncological orthopedic surgery, but more recently, additional applications have arisen. These implants are not without any risks and device failure is quite frequent. The most feared complication is undoubtedly the implants' infection; however, the exact incidence is still unknown. This systematic review aims to estimate in the current literature the overall incidence of megaprosthesis infections and to investigate possible risk/protective factors. METHODS: We conducted a systematic search for studies published from July 1971 to December 2023 using specific keywords. To be included, studies needed to report either the megaprosthesis anatomical site, and/or whether the megaprosthesis was coated, and/or the surgical indication as oncological or non-oncological reasons. RESULTS: The initial literature search resulted in 1281 studies. We evaluated 10,456 patients and the overall infection rate was 12%. In cancer patients, the infection rate was 22%, while in non-oncological patients, this was 16% (trauma 12%, mechanical failure 17%, prosthetic joint infections 26%). The overall infection rates comparing coated and uncoated implants were 10% and 12.5%, respectively. CONCLUSIONS: The number of megaprosthesis implants is increasing considerably. In traumatological patients, the infection rate is lower compared to all the other subgroups, while the infection rate remains higher in the cancer patient group. As these devices become more common, focused studies exploring epidemiological data, clinical outcomes, and long-term complications are needed to address the uncertainties in prevention and management.

RESUMEN

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.

RESUMEN

Background: Diabetic foot ulcers (DFUs) are serious complications that induce a high risk of lower extremity amputations and mortality. Compared with the standard of care, few reports analyzed the outcome of surgical treatment mainly for diabetic toe deformities and ulcers. The aim of this study is to collate evidence on the outcomes of interphalangeal resection arthroplasty (IP-RA) in preventing and treating diabetic toe ulcers distal to the metatarsophalangeal joint. Methods: A search strategy has been developed including electronic databases from inception. Only ulcers distal to the metatarsophalangeal joints were included. Noninfected and infected ulcers were also included at any toe location (dorsal/side/plantar). Outcomes were defined as healing rate, time to heal, ulcer recurrence, ulcer transfer, postintervention infection, wound dehiscence, and additional surgeries including amputation. Proportional meta-analysis was conducted for frequency outcomes. Results: Six observational studies comprising 217 patients with 244 IP-RA procedures were included. The mean follow-up period was 23.4 ± 8.2 months. Weighted frequencies were as follows: healing rate (93.6%), ulcer recurrence frequency (4.3%), ulcer transfer frequency (15.4%), postoperative infection (10.5%), wound dehiscence (17.8%), revision surgery (5%), and amputation rate (3.4%). The mean healing time was 4.3 ± 1.8 weeks. Conclusion: This review suggests that IP-RA is effective in preventing and treating diabetic toe deformities and ulcers with a modest rate of complications for this specific and often challenging clinical presentation.

RESUMEN

Two-stage revision with an antibiotic-loaded cement articulating spacer is a standard treatment for chronic prosthetic knee infection (PKI); however, mechanical complications can occur during the spacer period. There is limited evidence on the association between surgeon volume and mechanical complications after resection arthroplasty (RA) using an articulating spacer. This study aimed to compare the rates of mechanical complications and reoperation after RA with articulating spacers by surgeons with high volumes (HV) and low volumes (LV) of RA performed and analyzed the risk factors for mechanical failure. The retrospective study investigated 203 patients treated with PKIs who underwent RA with articulating spacers and were divided according to the number of RAs performed by the surgeons: HV (≥14 RAs/year) or LV (<14 RAs/year). Rates of mechanical complications and reoperations were compared. Risk factors for mechanical complications were analyzed. Of the 203 patients, 105 and 98 were treated by two HV and six LV surgeons, respectively. The mechanical complication rate was lower in HV surgeons (3.8%) than in LV surgeons (36.7%) (p < 0.001). The reoperation rate for mechanical complications was lower in HV surgeons (0.9%) than in LV surgeons (24.5%) (p < 0.001). Additionally, 47.2% of patients required hinge knees after mechanical spacer failure. Medial proximal tibial angle < 87°, recurvatum angle > 5°, and the use of a tibial spacer without a cement stem extension were risk factors for mechanical complications. Based on these findings, we made the following three conclusions: (1) HV surgeons had a lower rate of mechanical complications and reoperation than LV surgeons; (2) mechanical complications increased the level of constraint in final revision knee arthroplasty; and (3) all surgeons should avoid tibial spacer varus malalignment and recurvatum deformity and always use a cement stem extension with a tibial spacer.

RESUMEN

A 15-year-old girl with humeroradial synostosis since birth underwent a resection arthroplasty. A trapezoidal resection osteotomy of approximately 2 cm was performed at the anterior part of the bone flexure. This resulted at 18 months in an elbow arc of motion of 60°-110° and forearm pronation/supination of 40° and 60° without postoperative complications and improved disabilities of the arm, shoulder and hand and Hand 20 scores. Radiographic analysis revealed a humeroradial joint with a maintained pseudarthrosis and hinged motion at the humeroulnar joint. When performed by an experienced surgeon, resection arthroplasty corrects humeroradial synostosis, resulting in improvement in range of motion and quality of life. Level of Evidence: Level V (Therapeutic).

RESUMEN

Background: The most common treatment approach in periprosthetic joint infection (PJI) and chronic shoulder joint infection (SJI) is a two-stage revision involving interval placement of an antibiotic cement spacer or a resection arthroplasty. Knowing that Pyrocarbon has a smooth surface that prevents pathogen adhesion, the question arises whether it could be used as a temporary or permanent functional spacer? Purpose: The primary objective of the present study was to assess the rate of infection eradication after temporary or definitive implantation of Pyrocarbon Interposition Shoulder Arthroplasty (PISA) in patients with recalcitrant PJI or SJI. Our secondary objective was to assess mid-term clinical and radiographic outcomes. Methods: Fifteen patients (mean age: 52 ± 19 years) with chronic shoulder infection underwent, after joint débridement, implantation of PISA (InSpyre; Tornier-Stryker, Kalamazoo, MI, USA) with tailored perioperative antibiotics. In 7 cases, PJI occurred after hemiarthroplasty (n = 2), reverse shoulder arthroplasty (n = 2), hemireverse (n = 2), and resurfacing arthroplasty (n = 1). In 8 cases, SJI occurred in the context of failed surgery after fracture sequelae (n = 4), instability (n = 2), and cuff arthropathy (n = 2). Preoperatively, patients had a mean of 3 previous failed surgeries before PISA implantation. Patients were evaluated with clinical, laboratory, and radiographic assessment at a minimum of 2 years after surgery. Results: At a mean follow-up of 55 ± 18 months, no patient experienced reinfection after temporary (3 cases) or definitive (12 cases) PISA implantation. The adjusted Constant score increased from 33% ± 20 preoperatively to 65% ± 28 at last follow-up and SSV from 22% ± 19 to 63% ± 23 (P < .001). Active forward elevation increased from 27° ± 19 to 113° ± 30, external rotation from 7° ± 21 to 25° ± 25, and internal rotation level 3 ± 2 to level 5 ± 2 points (P < . 001). On final radiographs of definitive PISA, complete humeral densification, or a neocortex, formed around the implant in 64% (7/11). Conclusion: Our data suggest that, after washout, débridement and tailored antibiotics, PISA can be used as a temporary or definitive functional spacer for the treatment of recalcitrant shoulder infections and presents the following advantages: (1) PISA does not seem to be a risk for recurrent infection thanks to the antibacterial property of Pyrocarbon; (2) PISA can be used as a temporary or a definitive spacer without causing bone erosion, thanks to the low modulus of elasticity of Pyrocarbon; (3) PISA can be used as a salvage procedure in case of complete glenoid or humeral destruction, thanks to the sphericity of the implant needing no implant anchorage.

RESUMEN

Despite considerable legacy issues, Girdlestone's resection arthroplasty (GRA) remains a valuable tool in the armoury of the arthroplasty surgeon. When reserved for massive lysis in the context of extensive medical co-morbidities which preclude staged or significant surgical interventions, and/or the presence of pelvic discontinuity, GRA as a salvage procedure can have satisfactory outcomes. These outcomes include infection control, pain control and post-op function. We describe a case series of 13 cases of GRA and comment of the indications, peri, and post-operative outcomes.

RESUMEN

Introduction: Permanent resection or excision arthroplasty of the knee involves the removal of any infected prosthetic material and thorough debridement, with no further reimplantation. The more common alternatives to permanent resection arthroplasty include knee arthrodesis or above-knee amputation (AKA). Case Report: We describe two cases of complex periprosthetic infections of the knee associated with subsequent osteomyelitis, which were unsuitable for re-revision arthroplasty. Both patients chose to remain with an excision arthroplasty, rather than undergo arthrodesis or AKA, respectively, and were satisfied with their quality of life at long-term follow-up. Conclusion: Although permanent resection arthroplasty of the knee is rarely performed, it remains a limb salvage option in certain cases where bone loss is limited, functional demands are low, and further surgery may present a significant risk.

RESUMEN

PURPOSE: The purpose of our study was to investigate, in a cadaver model, the effect of increasing thumb metacarpophalangeal (MCP) joint hyperextension on thumb axial load and key pinch force after thumb trapeziectomy and flexor carpi radialis suspensionplasty. We developed a cadaveric model to test whether thumb MCP joint hyperextension after trapeziectomy would have a negative effect on key pinch force and increase loads across a reconstructed thumb carpometacarpal (CMC) joint. METHODS: We created a cadaveric biomechanical model that varied thumb MCP joint hyperextension while measuring thumb CMC axial and key pinch force under standardized loads. Direct observations were made of how key pinch and axial thumb CMC force change with increasing thumb MCP joint hyperextension. We measured the thumb key pinch force and axial thumb CMC joint load with the thumb MCP joint in 0°, 10°, 20°, 30°, 40°, 50°, and 60° of hyperextension. RESULTS: There was a 0.88 N (2.4%) increase in axial force across the thumb CMC per every 10° of increasing thumb MCP joint hyperextension. We found a 0.53 N (4.4%) reduction in key pinch force for every 10° of increasing thumb MCP joint hyperextension. Therefore, at 60° of thumb MCP joint hyperextension, the axial force across the thumb CMC increased by 5.3 N (14.6%) and the key pinch force was weakened by 3.2 N (26.6%). CONCLUSIONS: With progressive thumb MCP joint hyperextension after thumb CMC arthroplasty, we found a decrease in key pinch force and an increase in axial thumb CMC joint force. The decrease in key pinch force was larger than the relatively small increase in thumb CMC force. CLINICAL RELEVANCE: This study helps elucidate the biomechanics of the thumb CMC joint after resection arthroplasty with thumb MCP joint hyperextension and helps understand the interplay between these 2 conditions.

RESUMEN

The aim of this study was to assess the outcome of arthroscopic lunate fossa resection arthroplasty for patients with Kienböck's disease, previously managed without operation, and a non-functional lunate fossa. For adult patients with relapse or exacerbation of pain from Kienböck's disease 2 years after the onset of symptoms, arthroscopic removal of lunate fossa cartilage was performed to reach bleeding bone, if the cartilage in the lunate fossa was non-functional and the scaphoid fossa was intact. Sixteen patients (mean age 35 years; range 27-56) were included. At a mean follow-up of 39 months (range 24-64), the preoperative mean visual analogue pain scale and QuickDASH score decreased from 7 (SD 2.2) and 50 (SD 16) to 1.4 (SD 1.6) and 13 (SD 9.6), respectively. A minor deterioration in mean radioscaphoid angle and carpal height ratio occurred. Arthroscopic lunate fossa resection arthroplasty is a viable option for selected patients with Kienböck's disease.Level of evidence: IV.

RESUMEN

Shoulder arthrodesis and resection arthroplasty can be used as salvage procedures to treat severe complications after shoulder prosthesis failure. for both procedures, the indication and patient selection must be very strict. Shoulder arthrodesis after prosthesis failure can be indicated in young patients in case of chronic neuromuscular dysfunction. Filling the bony defect with either autologous or allogenic material and osteosynthetic primary stability are decisive for a good functional outcome. Aftercare comprises immobilization for 12 weeks and physical load is increased thereafter, depending on the sufficiency of bony consolidation. Resection arthroplasty after shoulder prosthesis failure is mostly reserved for multimorbid patients in case of a chronic infection. Thorough debridement and adequate systemic antibiotic treatment are crucial to achieve bacterial eradication.

RESUMEN

INTRODUCTION: The optimal treatment of patients with a degenerative joint disease secondary to an active or chronic septic arthritis of the hip is unclear. The aim of the present study was to report on our experience with two-stage total hip arthroplasty (THA) using a contemporary treatment protocol without spacer insertion. MATERIALS AND METHODS: Our prospective institutional database was used to identify all patients with degenerative septic arthritis treated with a non-spacer two-stage protocol between 2011 and 2017. Clinical outcomes included interim revision, periprosthetic infection (PJI) and aseptic revision rates. Restoration of leg-length and offset were assessed radiographically. Modified Harris hip score (mHHS) were obtained. Treatment success was defined using the modified Delphi consensus criteria. Mean follow-up was 62 months (13-110). RESULTS: A total of 33 patients with a mean age of 60 years (13-85) were included. 55% of the cohort was male and average Charlson Comorbidity Index (CCI) was 3.7 (0-12). 21 patients (64%) had an active/acute infection and 12 patients (36%) were treated for chronic/quiescent septic arthritis. Overall, 11 patients (33%) had treatment failure, including 5 patients who failed to undergo THA, 2 interim re-debridement for persistent infection, and 4 patients who developed PJI after an average of 7 months (0.3-13) following THA. The most common identified pathogen was Staphylococcus aureus (42.4%). No aseptic revision was recorded following THA. Leg-length and offset were successfully restored. Mean mHHS improved from 35.2 points to 73.4 points. CONCLUSION: Two-stage THA without spacer placement is a viable treatment option for destructive septic arthritis of the hip, demonstrating comparable rates of infection control and functional outcome. However, definitive resection arthroplasty is not uncommon in these often critically ill patients.

RESUMEN

BACKGROUND: Candida periprosthetic joint infections (PJIs) are a rare cause of prosthesis revision with severe consequences and challenging treatment. This study aims to produce a systematic analysis of types of treatment and outcome of knee Candida PJIs and their correlation with specific pathogen species. METHODS: During April 2021, a literature search was performed according to PRISMA (Preferred Reporting Item for Systematic Reviews and Meta-Analyses) guideline. Reviewers used the Oxford Level of Evidence (LoE) and Methodological index for non-randomized studies (MINORS) score. Modal value of surgical, pharmacological treatment and outcome along with the correlation between types of treatment and outcome was calculated through Chi-square or Fisher exact test. RESULTS: In total, 115 cases were collected through 51 articles, identifying 116 pathogens. Candida albicans was the most frequent pathogen. Analysis of LoE reveals 40 LoE 5 and 11 LoE 4. Thirteen patients underwent one-stage revision, 46 patients two-stage revision, 6 patients resection arthroplasty and arthrodesis, 4 patients long-term antifungal therapy, and 3 patients debridement with prosthesis retention. Global rate of success was 85.14%. Modal distribution revealed a preference for two-stage revision and Fluconazole in medical therapy. No difference in terms of fungal eradication was found among Candida species (p = 0.503) and for treatments except for two-stage revision and resection arthroplasty (p = 0.0125) or debridement with implant retention (p = 0.0498), and the rest of procedures and resection arthroplasty (0.0192). MINORS score was poor. CONCLUSIONS: Analysis of the literature did not highlight any difference between types of surgical treatment and pathogens in terms of relapse or infection eradication. However, two-stage replacement may be preferred, allowing healing of infection in most cases.

RESUMEN

BACKGROUND: Joint infections or the complications of hip surgery may necessitate a Girdlestone resection arthroplasty. This is often kept as a last resort for patients with significant co-morbidities or when other treatments have been ineffective. The aim of this study was to define the outcome after Girdlestone excision arthroplasty when undertaken as a primary or secondary procedure for a hip fracture. PATIENTS AND METHODS: This is a retrospective review of a prospectively collected database involving 36 patients who underwent a Girdlestone procedure over a 30-year period. It compares the outcome for the 19 patients who survived to 1 year with those of 38 matched hip fracture patients. RESULTS: Pain persisted in most patients after the procedure and was universal in those patients who could walk. Most patients experienced a significant loss of independence and a reduction in mobility status: 12/19 (63.1%) of those who survived to 1 year were immobile and of the remainder, all needed a Zimmer frame to walk. Overall, 41.7% of patients had died within 1 year of undergoing the procedure. CONCLUSIONS: This study concludes that Girdlestone resection arthroplasty after a hip fracture is associated with a high degree of morbidity and mortality and therefore, should only be used as a salvage procedure after all other surgical measures have been exhausted.

RESUMEN

Purpose: Hip resection arthroplasty as a definitive treatment is an uncommon indication, although still in use selectively. This study evaluates a cohort of patients who have undergone hip resection arthroplasty surgery indicated as a definitive treatment, in order to assess the rate of re-operation, the rate of infection, and the mortality rates. Methods: We conducted a retrospective, observational, descriptive analysis of a cohort of patients who had undergone a hip resection arthroplasty intended as a definitive treatment, in two University Hospitals from 1994 to 2020. The exclusion criteria were the implantation of a hip cement spacer, or a temporary hip resection arthroplasty in patients undergoing a two-staged surgical approach. We found 26 cases of hip resection arthroplasty. We recorded the indications for a definitive hip resection arthroplasty, the outcomes and complications, and analyzed the success of the hip resection arthroplasty as a definitive surgery using a Kaplan-Meier curve. Results: Seven cases (26.9%) required a re-operation after the hip resection arthroplasty, four cases for persistent hip infection, and in the three remaining a conversion to a total hip arthroplasty was re-considered due to a good medical evolution and non-tolerance to the low functional outcome. The mortality rate was 61.5% (27 days-20 years), with a 19.2% mortality rate in the first 5 years. All the cases that required another surgery after the hip resection arthroplasty were re-operated within the first 18 months. Conclusion: Unfortunately, hip resection arthroplasty continues to show elevated re-operation rate and early mortality rate, as well as low functional outcomes. Two-staged hip revision arthroplasty is the surgical treatment of choice in patients suffering from a periprosthetic joint infection, however we believe that hip resection arthroplasty should be considered in fragile patients, who have endured multiple revision surgeries, or their comorbidities make them unfit from further surgeries.

RESUMEN

BACKGROUND: Girdlestone resection arthroplasty is a salvage procedure for hip periprosthetic joint infection (PJI) that controls infection and reduces chronic pain, but may result in limited postoperative joint function. The aim of this study was to assess physical function and mental health after Girdlestone. METHODS: This was a multicenter, prospective study evaluating patients with Girdlestone. The Prosthesis Evaluation Questionnaire (PEQ) and patient-reported outcomes measurement information system (PROMIS) global physical health and mental health surveys were administered postoperatively via telephone. The PEQ consists of four scales (ie, ambulation, frustration, perceived response, and social burden) with scores ranging from 0 to 10. The PROMIS measures generated T-scores (mean: 50, standard deviation: 10) that enable comparison to the general population. RESULTS: Thirty-five patients completed all surveys. The average time from procedure to survey completion was 6 years (range, 1 to 20). The median scores for the ambulation, frustration, perceived response, and social burden scales of the PEQ were 0.0 [interquartile range: 0-4.1], 6.0 [3.0-9.3], 9.0 [7.2-10.0], and 7.5 [4.3-9.5]. The median raw scores of the PROMIS global physical health and mental health were 11.91 [interquartile range: 9-14] and 14.0 [10.0-16.0]. These corresponded to average T scores of 39.7 (standard error : 4.3) for physical health and 46.1 (standard error: 3.8) for mental health, which were 10.3 points and 3.9 points below the average score in the United States general population, respectively. CONCLUSION: Girdlestone can have a substantial negative impact on physical functions; however, mental health and social interaction may be only moderately affected. These outcomes can be used to guide patient expectations, as this procedure may be necessary in certain salvage scenarios.

RESUMEN

Purpose Scapholunate advanced collapse (SLAC) wrist results from an untreated scapholunate dissociation and is the most common type of degenerative arthritis of the wrist. The most common surgical treatments for SLAC wrist are proximal row carpectomy and four-corner fusion with scaphoid excision. Arthroscopic surgical treatment for SLAC wrist has been reported; however, only limited data on functional outcomes are available. The purpose of this study is to report our 5-year follow-up clinical outcomes for arthroscopic treatment for SLAC wrist. Methods Thirty-one consecutive cases of arthroscopic resection arthroplasty for SLAC wrist were reviewed. Preoperative and postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) scores, range of motion, grip strength, and pain (on 0-10 scale) as well as postoperative satisfaction (0 = not satisfied, 5 = completely satisfied) were recorded. Grip and range of motion were measured by an occupational therapist. Results The preoperative pain score was 7 and 0.18 postoperatively. The mean satisfaction at final follow-up was 4.8. Preoperative and final follow-up scores of the mean DASH was 48 and 3, respectively. The total arc of motion was 114 degrees preoperatively and 126.5 degrees postoperatively. Mean grip strength before surgery was 41 and 49 kg at final follow-up. Conclusion Arthroscopic resection arthroplasty for SLAC wrist results in significant improvement in patient function as measured by DASH and pain scores. Type of Study/Level of Evidence Therapeutic IV.

RESUMEN

BACKGROUND: Several surgical procedures have been described to treat hallux rigidus. Keller arthroplasty is a joint-sacrificing procedure proposed in 1904. Considering the current trends to mini-invasiveness and the debate about the technique's suitability, this review intends to state Keller arthroplasty results and the conditions where it could be still adopted in the treatment of hallux rigidus. METHODS: Selected articles were reviewed to extract: population data, surgical indications, different surgical techniques, clinical and radiological outcomes, and complications. RESULTS: Seventeen retrospective studies were selected, counting 508 patients. Mean age at surgery was 55 years. Patients were affected by moderate-severe hallux rigidus. Three modified Keller arthroplasty were identified. Good clinical and radiological outcomes were reported. Metatarsalgia was the most frequent complication (12%). CONCLUSION: Despite for many authors KA seems a viable surgical treatment for middle aged and elderly patients affected by moderate-severe hallux rigidus, the available literature provides little evidence on the real efficacy and safety of the technique. A non-negligible percentage of complications may occur, and therefore is essential to set correct indications through an accurate patients' selection.
