RESUMEN
Background: The primary objective of the present study was to investigate how preoperative imaging modalities including 3D computed tomography (CT) scans with preoperative planning software affect implant choice for shoulder arthroplasty. Methods: X-ray, uncorrected 2D CT scans, and 3D CT scans from 21 patients undergoing primary arthroplasty were reviewed by five shoulder surgeons. Each surgeon measured glenoid version, inclination and humeral head subluxation, and then selected an anatomic or reverse shoulder arthroplasty implant based only on these imaging parameters. Each surgeon virtually positioned the implant. Agreement between surgeons and changes in plan for individual surgeons between imaging modalities were assessed. Results: Average measurements of native version, inclination, and subluxation were similar across all imaging modalities with very good interobserver reliability. Overall, there was a high rate of variability in choice of implant depending on imaging modality. Agreement on implant selection between surgeons improved from 68.6% using x-ray to 80.0% with 3D CT. Introducing age added significant variability, reducing agreement on implant choice to 61.0% with 3D CT. Conclusions: The use of preoperative 3D planning changes implant choice in nearly one-third of cases compared to plain radiographs and improves surgeon agreement on implant choice compared to x-ray and 2D CT.Level of evidence: III.
RESUMEN
Reconstruction of soft tissue defects in the lower leg and foot after traumatic injury is a challenging problem owing to lack of locally reliable flaps. The traditional options for wound coverage often do not provide feasible or adequate treatment for many of these wounds. The lack of skin laxity in the lower leg and foot often make local flaps unavailable. Split-thickness skin grafts will not be robust enough. Free tissue flaps have a litany of potential complications and guaranteed comorbidities. The present case reinforces that appropriately selected patients with significant open bony and soft tissue trauma to the foot and ankle can be treated with a reverse sural artery fasciocutaneous flap. The reverse sural artery flap allows for full-thickness skin coverage with its own blood supply, maximizing the healing potential and should be considered a viable first option for soft tissue coverage.

A total of 262 feet in 228 consecutive patients underwent first metatarsophalangeal joint (MPJ) fusion; thus, the present study is the largest single-surgeon patient series reported. The inclusion criteria included severe painful deformity of the first MPJ due to osteoarthritis, rheumatoid arthritis, or gouty arthritis and stage 3 or 4 hallux rigidus. The exclusion criteria were revision surgery of the first MPJ, fixation other than with dual crossed screws, and a postoperative follow-up period of <3 months. Fusion of the first MPJ was fixated with dual-crossed 3.0-mm screws. The office follow-up period was ≥3 months postoperatively and the survey follow-up period was ≥6 months postoperatively. The mean duration to radiographic evidence of arthrodesis was 7.00 ± 2.33 weeks, and 252 of the feet (96.18%) achieved successful arthrodesis. The mean postoperative office follow-up duration was 30.43 ± 6.59 weeks. The mean modified American College of Foot and Ankle Surgeons scale score was 51.2 ± 3.28 of maximum possible of 68 points. The mean subjective score was 37.1 ± 2.5 (maximum possible of 50 points), and the mean objective score was 14.5 ± 1.7 (maximum possible of 18 points). Furthermore, 200 patients (87.72%) reported that they had little to no pain, 187 (82.02%) reported they either mostly liked the appearance of their toe or liked it very much, and 173 (75.88%) reported that they could wear any type of shoe most or all the time after the operation. Of the respondents, 207 (90.79%) stated they would have the surgery repeated, and 197 (86.40%) would recommend the surgery to a family member or friend.

Plantar plate pathology has gained noticeable attention in recent years as an etiology of lesser metatarsophalangeal joint pain. The heightened clinical awareness has led to the need for more effective diagnostic imaging accuracy. Numerous reports have established the accuracy of both magnetic resonance imaging and ultrasonography for the diagnosis of plantar plate pathology. However, no conclusions have been made regarding which is the superior imaging modality. The present study reports a case series directly comparing high-resolution dynamic ultrasonography and magnetic resonance imaging. A multicenter retrospective comparison of magnetic resonance imaging versus high-resolution dynamic ultrasonography to evaluate plantar plate pathology with surgical confirmation was conducted. The sensitivity, specificity, and positive and negative predictive values for magnetic resonance imaging were 60%, 100%, 100%, and 33%, respectively. The overall diagnostic accuracy compared with the intraoperative findings was 66%. The sensitivity, specificity, and positive and negative predictive values for high-resolution dynamic ultrasound imaging were 100%, 100%, 100%, and 100%, respectively. The overall diagnostic accuracy compared with the intraoperative findings was 100%. The p value using Fisher's exact test for magnetic resonance imaging and high-resolution dynamic ultrasonography was p = .45, a difference that was not statistically significant. High-resolution dynamic ultrasonography had greater accuracy than magnetic resonance imaging in diagnosing lesser metatarsophalangeal joint plantar plate pathology, although the difference was not statistically significant. The present case series suggests that high-resolution dynamic ultrasonography can be considered an equally accurate imaging modality for plantar plate pathology at a potential cost savings compared with magnetic resonance imaging. Therefore, high-resolution dynamic ultrasonography warrants further investigation in a prospective study.

OBJECTIVE: Inconclusive findings about infection risks, importantly the use of immunosuppressive medications in patients who have undergone large-joint total joint arthroplasty, challenge efforts to provide evidence-based perioperative total joint arthroplasty recommendations to improve surgical outcomes. Thus, the aim of this study was to describe risk factors for developing a post-operative infection in patients undergoing TJA of a large joint (total hip arthroplasty, total knee arthroplasty, or total shoulder arthroplasty) by identifying clinical and demographic factors, including the use of high-risk medications (i.e., prednisone and immunosuppressive medications) and diagnoses [i.e., rheumatoid arthritis (RA), osteoarthritis (OA), gout, obesity, and diabetes mellitus] that are linked to infection status, controlling for length of follow-up. METHODS: A retrospective, case-control study (N = 2212) using de-identified patient health claims information from a commercially insured, U.S. dataset representing 15 million patients annually (from January 1, 2007 to December 31, 2009) was conducted. Descriptive statistics, t-test, chi-square test, Fisher's exact test, and multivariate logistic regression were used. RESULTS: Male gender (OR = 1.42, p < 0.001), diagnosis of RA (OR = 1.47, p = 0.031), diabetes mellitus (OR = 1.38, p = 0.001), obesity (OR = 1.66, p < 0.001) or gout (OR = 1.95, p = 0.001), and a prescription for prednisone (OR = 1.59, p < 0.001) predicted a post-operative infection following total joint arthroplasty. Persons with post-operative joint infections were significantly more likely to be prescribed allopurinol (p = 0.002) and colchicine (p = 0.006); no significant difference was found for the use of specific disease-modifying anti-rheumatic drugs and TNF-α inhibitors. CONCLUSION: High-risk, post-operative joint infection groups were identified allowing for precautionary clinical measures to be taken.

UNLABELLED: Plantar plate pathology has gained considerable attention in recent time, and with this increased awareness multiple treatments have been proposed. There have been no comparison studies between these treatments. The authors feel a direct approach for anatomic repair allows for plantar plate repair and tightening to desired tension, without any plantar prominences or potentially irritating hardware. In addition if the plantar plate is found to be attenuated or there is a lack of residual tissue, the described imbrication utilizing the flexor digitorum longus sheath, which is not possible with hardware or newest instrumentation, allows for a robust repair. The presented case series provides results from consecutive patients treated with proposed concurrent plantar and dorsal incisions, providing proof of concept and viability of novel technique. LEVELS OF EVIDENCE: Level V: Case series.

BACKGROUND: Failure of structural healing is not infrequent after rotator cuff repair and often is not associated with clinical outcome. The goals of this study are to describe outcomes in a cohort of patients with a failed rotator cuff repair and to evaluate factors associated with clinical outcome. METHODS: This was a retrospective study of all patients with failure of structural integrity after rotator cuff surgical repair. A threshold American Shoulder and Elbow Surgeons (ASES) score of 80 points was used to allocate patients into either the successful (≥80 points; Group 1) or unsuccessful (<80 points; Group 2) cohorts. Demographics, patient-centered instruments for shoulder function, radiographic parameters, and shoulder motion were compared between groups. RESULTS: On the basis of the postoperative ASES score, thirty-three patients (54.1%) were included in Group 1 and twenty-eight patients (45.9%) were included in Group 2. Fifteen patients (53.6%) in Group 2 reported a labor-intensive occupation compared with two patients (6.1%) in Group 1 (p < 0.001). Multiple regression analysis demonstrated that labor-intensive occupation (odds ratio [OR], 202.3; p = 0.026), preoperative Simple Shoulder Test (SST) score (OR, 0.50; p = 0.028), and preoperative external rotation (OR, 0.91; p = 0.027) were associated with inclusion in Group 2. Age and other demographic variables, including sex, dominant-sided surgery, and medical comorbidities, were similar for the groups. CONCLUSIONS: Successful outcomes were achieved in 54% of patients with failed rotator cuff repair. Those who self-identified their occupation as being labor-intensive represented a special group of patients who are at high risk for a poor outcome after a failed rotator cuff repair.

Isolated dislocation of the posterior tibial tendon is an uncommon pathologic entity that typically occurs in the setting of acute trauma. The diagnosis remains challenging and is often delayed second to the rarity of the injury and symptoms similar to that of medial ankle sprains and other routinely diagnosed injuries about the ankle. The factors that predispose this tendon to dislocation include a hypoplastic retromalleolar groove, flexor retinaculum insufficiency, chronic repetitive trauma, and a structural abnormality from a previous medial malleolar fracture, or a combination thereof. Dislocation has also been cited as a complication of multiple local steroid injections and tarsal tunnel release. The mechanism of injury appears to involve forced dorsiflexion and eversion of the ankle when the posterior tibial tendon is contracted. Most cases do not respond well to conservative treatment and will require surgery to restore function and eliminate symptoms. We report a case of posterior tibial tendon dislocation related to a snowboarding injury and offer our technique for surgical correction.

BACKGROUND: The purpose of this study was to examine the baseline function and results of arthroscopic cuff repair in shoulders with small and medium-sized full-thickness cuff tears with complete supraspinatus disruption compared with those with an intact anterior supraspinatus tendon. METHODS: The study evaluated 112 subjects with small and medium-sized cuff tears. Subjects were grouped according to anterior supraspinatus integrity (83 shoulders intact, group 1; and 29 shoulders with anterior supraspinatus tendon disruption, group 2). Functional assessments included visual analogue scale for pain, American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test score, and Constant score. Repair integrity was assessed by ultrasound examination. RESULTS: Group 2 shoulders had greater mean tear width, length, and area (P < .0001) and greater supraspinatus muscle degenerative changes (P < .0001) compared with shoulders with an intact anterior supraspinatus tendon. There were no differences in demographics or baseline function (ASES score: 45 group 1 vs 46 group 2, P = .79; Constant score: 56 group 1 vs 52 group 2, P = .29) before surgery. There were no differences in any functional parameter (ASES score: 92 group 1 vs 93 group 2, P = .71; Constant score: 84 group 1 vs 85 group 2, P = .84) after surgery. There was no difference in tendon healing rates (93% group 1 vs 86% group 2; P = .26). CONCLUSIONS: In the setting of painful small and medium-sized rotator cuff tears, disruption of the anterior supraspinatus tendon was associated with greater tear size and more advanced supraspinatus muscle degeneration. However, anterior supraspinatus tendon integrity had no influence on the clinical presentation or the functional and structural results of cuff repair surgery.

The goal of wound healing is to obtain the best closure through the least morbid means. In the surgical treatment of the diabetic foot and ankle, the reconstructive foot and ankle surgeon is tasked with the challenge of repairing a variety of tissue defects. The decision for wound closure depends on the location of the wound and host factors. In order of increasing complexity, the clinician should consider the reconstruction decision ladder algorithm. Wound evaluation coupled with the knowledge of various closure techniques and their indications will arm the surgeon with the tools for a successful closure.

RESUMEN
Functionally limiting heterotopic ossification about the shoulder represents an uncommon clinical entity, which has been most commonly reported as a consequence of prolonged immobilization in intensive care unit patients. Severe cases may result in complete glenohumeral ankylosis, with resultant upper extremity motion through the scapulothoracic joint, and significant functional consequences. We report the case of a 72-year-old male with spontaneous glenohumeral ankylosis who suffered a humeral shaft fracture with resultant painless nonunion. Motion through the nonunion site caused significant subjective functional improvements, increased range of motion, and the ability to complete his activities of daily living. Patients with limited shoulder range of motion may be at higher risk for humeral fractures and nonunion. These patients, however, may experience improved function due to increased upper extremity range of motion through the nonunion site.

BACKGROUND: Interest in double-row techniques for arthroscopic rotator cuff repair has increased over the last several years, presumably because of a combination of literature demonstrating superior biomechanical characteristics and recent improvements in instrumentation and technique. As a result of the increasing focus on value-based health-care delivery, orthopaedic surgeons must understand the cost implications of this practice. The purpose of this study was to examine the cost-effectiveness of double-row arthroscopic rotator cuff repair compared with traditional single-row repair. METHODS: A decision-analytic model was constructed to assess the cost-effectiveness of double-row arthroscopic rotator cuff repair compared with single-row repair on the basis of the cost per quality-adjusted life year gained. Two cohorts of patients (one with a tear of <3 cm and the other with a tear of ≥3 cm) were evaluated. Probabilities for retear and persistent symptoms, health utilities for the particular health states, and the direct costs for rotator cuff repair were derived from the orthopaedic literature and institutional data. RESULTS: The incremental cost-effectiveness ratio for double-row compared with single-row arthroscopic rotator cuff repair was $571,500 for rotator cuff tears of <3 cm and $460,200 for rotator cuff tears of ≥3 cm. The rate of radiographic or symptomatic retear alone did not influence cost-effectiveness results. If the increase in the cost of double-row repair was less than $287 for small or moderate tears and less than $352 for large or massive tears compared with the cost of single-row repair, then double-row repair would represent a cost-effective surgical alternative. CONCLUSIONS: On the basis of currently available data, double-row rotator cuff repair is not cost-effective for any size rotator cuff tears. However, variability in the values for costs and probability of retear can have a profound effect on the results of the model and may create an environment in which double-row repair becomes the more cost-effective surgical option. The identification of the threshold values in this study may help surgeons to determine the most cost-effective treatment.

BACKGROUND: Open calcaneal fractures are devastating, high-energy injuries frequently occurring in multiply-injured patients. Unsatisfactory outcomes with significant complications rates are frequently reported. Our purpose was to assess outcomes of delayed ORIF for open calcaneal fractures with medial hindfoot wounds and limited posterior facet comminution. MATERIALS AND METHODS: Following acute management of the open fractures, seven patients were determined to have stable medial hindfoot wounds and posterior facet comminution of three or fewer fracture fragments. The average age was 32.5 years. These patients were treated with operative management with a plate-and-screw construct using the extensile lateral approach. RAND-36 Item Health, AOFAS Ankle-Hindfoot Survey, and physical examinations were undertaken to access outcomes. RESULTS: All open calcaneal injuries were initially treated with irrigation and debridement, intravenous antibiotics, and plaster immobilization. Definitive fixation was performed at an average of 11.7 days. Six of seven patients were multiply injured. Prior to injury, five were employed on a full-time basis. Four returned to their original or a comparable job. The results of the RAND-36 Item Health Survey and the AOFAS Ankle-Hindfoot scores were 56.7 and 71, respectively. There were no postoperative infections. No patients required additional operative hindfoot procedures. Five continued to use tobacco products. None reported chronic narcotic usage. CONCLUSION: Aggressive treatment of select open calcaneal fractures with delayed ORIF produced satisfactory functional results. Most patients were able to return to gainful employment. There were no infections or wound complications.
