Purpose: Untreated episodes of shoulder instability can have major consequences on athletic careers. Operative shoulder stabilization reduces the rate of recurrent instability and allows for high rates of return to sport (RTS). Basketball players who experience an episode of instability have high rates of recurrence, though little is known about postoperative player performance. The purpose of this study was to identify the impact of shoulder instability and surgical stabilization on player performance and career lengths in the National Basketball Association (NBA). Methods: NBA players who had episodes of shoulder instability between 1994-2014 were identified using the NBA Injury Surveillance and Analytics Database. Players were stratified according to operative versus nonoperative treatment of shoulder instability. Two demographic- and performance-matched controls were chosen for each test subject. Univariate analyses were used to compare pre- and postoperative player performance metrics. Survival analysis was used to assess the effect of shoulder surgery on postoperative career lengths. Results: Fifty athletes were identified, 46 (92.0%) returned to play in the NBA. Compared to controls, there was no significant difference in postoperative performance according to either 1- or 3-year averages. Survival analysis demonstrated no significant difference in postoperative career lengths between athletes with a history of shoulder surgery for instability and matched controls. Conclusion: NBA players return to professional basketball in high numbers following orthopedic surgery for shoulder instability. Shoulder instability may not be a career-altering event, as there are highly effective methods of shoulder stabilization available to athletes.

Purpose: The purpose of this study is to present one institution’s experience managing chronic exertional compartment syndrome (CECS) and to identify patient and surgical characteristics associated with better outcomes following open surgical management of CECS with specific emphasis on return to sports. Methods: Fifteen patients (10 male, 5 female) who underwent open fasciotomy for CECS with a minimum of 1-year follow-up were included. Chart review was performed to obtain patient demographics, medical and surgical history, presenting symptomatology, and surgical details of fasciotomy. Outcomes were assessed using follow-up questionnaires that consisted of Tegner Activity Scale, EuroQol-5D (EQ5D) index score, EQ-5D rating scale, symptom resolution, patient satisfaction, and return to sports. Results: The mean patient age at the time of surgery was 28.1 years (range: 17 to 49 years). At mean follow-up of 2.7 years (range: 1.0 to 5.1 years), five patients reported complete resolution of symptoms, eight reported improvement (but not resolution) of symptoms, one reported no change in symptoms, and one reported worsening of symptoms. The mean Tegner Activity Score was 6.7 (range: 1 to 9) prior to injury and 4.7 (range: 1 to 9) postoperatively. Patients with any preoperative symptoms at rest had significantly lower Tegner before score (4.0 vs. 7.1, p = 0.036) and EQ5D rating (50.0 vs. 83.5, p = 0.04) compared to those that only experienced symptoms with activity. Patients that had prior surgery, including fasciotomy, had significantly lower EQ-5D rating than patients with no history of prior lower extremity surgery (56.7 vs. 84.6, p = 0.045). Although 10 (66%) patients were able to return to sports, only four (27%) of them were able to return to their prior level of sport. The overall satisfaction rate was 87%. Conclusion: Although open surgical fasciotomy for treatment of chronic exertional compartment syndrome leads to high rates of symptom improvement or resolution, fewer patients are able to return to their prior level of sports. Presence of symptoms at rest, presence of bilateral symptoms, and history of prior lower extremity surgery all portend worse outcomes.

Background: Total hip arthroplasty (THA) is a frequently performed, highly successful orthopedic procedure. Although primary osteoarthritis (PA) is the most common reason for (THA), there are several secondary conditions that lead to degenerative hip disease that are successfully treated with THA. The purpose of this study was to examine the incidence of these secondary causes of arthritis (SA) leading to THA and to compare the relative surgical costs, operating times, and hospital length of stay (LOS) for THA done for PA versus SA. Methods: Electronic medical records from 836 continuous patients undergoing primary THA over a 2-year period were reviewed at a single high-volume joint arthroplasty center. Data obtained included age, sex, laterality, diagnosis leading to THA, surgical costs based on hospital fees, operating room time, and hospital LOS. Using operative reports, office visit notes, and radiology reports or images, patients were categorized into PA or SA groupings. PA was defined as osteoarthritis of no other known etiology, whereas SA was defined when a known underlying diagnosis led to degenerative joint disease of the hip. SA included hip dysplasia, post-traumatic arthritis (PTA), avascular necrosis (AVN), inflammatory arthropathy, Perthes disease, and slipped capital femoral epiphysis (SCFE). Means and proportions of the variables from both groups were analyzed and compared using t-tests and chi-squared tests where applicable. Results: There were 599 patients in the PA group and 237 patients in the SA group. The SA group was significantly younger than the PA group (54.4 years versus 64.0 years; p = 0.0001). The SA cohort had significantly higher mean surgical costs ($29,662 versus $27,078; p = 0.0005), operating room times (189 minutes versus 179 minutes; p = 0.0042), and LOS (4.2 days versus 3.9 days; p = 0.0312). Within the SA group, the hip dysplasia subgrouping had the lowest cost and operating room time, whereas the PTA subgrouping had the highest cost and operating room time. Conclusions: More than a quarter of primary THAs are performed due to secondary arthritis, most commonly due to hip dysplasia. Cases of THA due to secondary arthritis are associated with significantly increased hospital costs, operating time, and postoperative length of stay compared to THA’s performed for primary osteoarthritis. Patients with post-traumatic hip arthritis may contribute the highest economic burden and present the most complex cases for arthroplasty surgeons.

Background: Open subpectoral biceps tenodesis (OSBT) with cortical button fixation can deliver acceptable results for long head of the biceps (LHB) pathology with the benefit of smaller bone tunnel diameter and a potential reduced risk of postoperative humeral shaft fracture. However, functional outcomes and complications of a button-only technique with a small diameter tunnel in the subpectoral region have not been studied sufficiently. Purpose: We sought to determine whether OSBT with cortical button fixation results in significant functional improvements from preoperative to final follow-up. The secondary purpose was to determine whether there is a lower risk of major postoperative complications. Methods: A retrospective review of patients who underwent OSBT with cortical button fixation at one institution was conducted with objective measurements and clinical outcomes collected with a minimum of 2 years of follow-up. Surgical data was collected for analysis. Objective measures obtained at follow-up included physical exam, strength testing using a handheld dynamometer, and Long-Head of the Biceps score. Clinical outcomes were measured using the following validated questionnaires preoperatively and postoperatively: American Shoulder and Elbow Surgeons score (ASES), Disabilities of the Arm, Shoulder and Hand score (DASH), and Oxford Shoulder Score (OSS). Results: Sixty-one patients with mean age of 53.1 ± 10.1 years at the time of surgery were enrolled in the study. Mean follow-up time was 42.4 ± 16.9 months (range: 24 to 64 months). The postoperative LHB score was 95.5 ± 6.1 (range: 77 to 100). All functional outcome measures (ASES, DASH, and OSS) demonstrated statistically significant improvements at final follow-up (p < 0.05 for each). At total of 92.5% of patients stated they would have the procedure again if necessary. Mean elbow flexion strength on the operative side measured 98.7% ± 15.9% (range: 74.1% to 142.3%) of the contralateral arm. The mean LHB tendon diameter was 5.7 ± 0.8 mm and mean tunnel diameter was 5.9 ± 0.7 mm. There were no cases of intraoperative or postoperative fracture, infection, or Popeye deformity noted during the follow-up period. Conclusion: Subpectoral biceps tenodesis with cortical button fixation is a safe and effective surgical treatment option to relieve pain and restore function.

Introduction: The United States is experiencing an opioid epidemic, and orthopedists prescribe a large proportion of these drugs. Patients often become dependent on painkillers and face barriers to treatment. Given that many joint arthroplasty patients are enrolled in Medicare, we aimed to examine the ease of orthopedic patients with various insurance types to access addiction and pain specialists. Methods: Using three web-based directories, we identified addiction specialists within a 5-mile radius of our hospital. We contacted these practices and inquired as to whether they treated addiction, types of insurance they accepted, and appointment availability. Results: We identified 190 addiction and pain management specialists and were able to reach 134/190 (70.5%). Nine (6.7%) of the 134 reachable physicians accepted Medicare or Medicaid, which is nine (4.7%) of the 190 physicians initially located. The average wait time to an appointment was 4.2 days, and a significant difference in wait time existed across insurance types (p = 0.0284). Discussion: Orthopedic patients face many barriers to receiving treatment for painkiller addiction. Wait time to see an addiction specialist also varied based on insurance type. Online directories may not be useful for certain patient populations to identify physicians. Orthopedic surgeons should partner with addiction and pain specialists to help alleviate the barriers that patients face

Background: Supracondylar humerus fractures account for two thirds of all hospitalizations for elbow injuries in children. A prevailing assumption exists regarding whether treatment quality varies by surgeon training background. This study compares radiographic outcomes of pediatric supracondylar humerus fractures treated by fellowship trained pediatric orthopedists (PO) and non-pediatric orthopedists (adult traumatologists, AT) with regard specifically to ability to obtain and maintain an operative closed reduction. Methods: We retrospectively reviewed all pediatric patients between 2007 and 2013 operatively treated for closed extension-type supracondylar humerus fractures. Inclusion criteria included skeletally immature patients with Gartland classification type II and III fractures. Eighty-five cases were included with 37 fractures treated by four fellowship trained adult traumatologists at a level I trauma center and 48 fractures treated by five fellowship trained pediatric orthopedists at a tertiary referral center. Radiographs were analyzed for Baumann’s angle and shaft-condylar angle, then statistical comparisons were performed to compare preoperative and postoperative measurements. Results: There was no difference in age, gender, laterality, fracture classification, use of medial pins, or neurovascular injuries between PO and AT (p > 0.05). Change in Baumann’s angle (p = 0.61) or shaft-condylar angle (p = 0.87) did not differ between PO and AT. There was no significant difference in operative and postoperative Baumann’s angle (p = 0.18 and p = 0.59, respectively) and shaft-condylar angle measurements (p = 0.05 and p = 0.09, respectively) between PO and AT. There was no difference in loss of reduction between the two groups (p = 0.64). Conclusions: Radiographic analysis of supracondylar humerus fractures showed no significant difference in alignment or loss of reduction when treated by pediatric orthopedists compared to non-pediatric orthopedists. Though it seems that the trend is to send pediatric fracture care to tertiary referral centers it may not be necessary for simple fracture management

Purpose: High tibial osteotomy (HTO) is an invaluable tool in the treatment of a variety of conditions in active patients with varus malalignment of the knee. The polyetheretherketone (PEEK) iBalance HTO system has been designed to make the osteotomy safer, more reproducible, and avoid metal hardware related complications. The purpose of this study was to evaluate short-term outcomes in patients who underwent an open wedge high tibial osteotomy with the iBalance HTO system. Methods: We identified patientswho underwent HTO using iBalance with a minimum of 2-year follow-up. Medical records were reviewed for demographics, Workers Compensation and no-fault insurance claims, history of smoking, concomitant procedures, degree of correction, and complications. Patient outcomes using Knee injury and Osteoarthritis Outcome Score (KOOS) and visual analog scale (VAS) were recorded before undergoing HTO and compared with those recorded after a 2-year follow-up. Statistical analysis was performed using paired sample t-tests with p < 0.05 considered significant. Results: Twenty-three patients with mean age of 44.9 (± 8.48) were identified. The mean correction angle was 9.9° (range: 5° to 15°). Sixteen patients underwent a concomitant procedure. The average follow-up was 2 years (range: 2 to 3.5 years). Six patients reported a positive history of smoking. The mean preoperative KOOS scores of symptoms, pain, activities of daily living (ADL), sport, and quality of life were 14 (± 18.5), 53.1 (± 14.8), 69.1 (± 21.7), 29.2 (± 22.0), and 30.0 (± 20.0), respectively. The mean preoperative VAS score was 5.5 (± 2.5). At follow-up, the mean scores of symptoms, pain, ADL, sport, and quality of life all improved to 67.53 (± 24.9), 68.06 (± 23.4), 75.74 (± 25.3), 45.91 (± 36.1), and 43.47 (± 33.4), respectively. The mean VAS at follow-up was 1.9 (± 2.1). There was a significant increase (p < 0.05) in all KOOS categories, except ADL. Additionally, there was a statistical difference between smoking and change in ADL score. Former smokers demonstrated an average decrease of 10.3 points, increasing their disability, and nonsmokers increased 15.3 points on the KOOS ADL scale, decreasing their disability. There were three complications (DVT, cellulitis, and serosanguinous drainage) within a month after the procedure. There were three complications, including a revision HTO, pes anserine bursitis, and lateral hamstring tendinitis, within the 2-year follow up including one revision after 1 year. Five patients went on to total knee arthroplasty at an average of 3 years (range: 1 to 5 years). Conclusion: This study suggests that the iBalance medial opening wedge HTO system implant can be used with comparable outcomes to traditional methods, however the conversion rate to total knee arthroplasty may be higher than previously reported. This appears to be unrelated to implant choice and likely related to extended indications for the procedure in younger patients refusing knee arthroplasty. The iBalance medial opening wedge HTO system has shown to be safe, removing many of the complications existing with other osteotomy implant options. Our findings highlight the importance of additional studies in order to investigate the risk factors causing progression from HTO to TKA.

Background: Total hip arthroplasty is increasingly being performed as a same day procedure. Additionally, greater emphasis is being placed on patient satisfaction surveys such as the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS)® Survey. This study aims to assess if patients who undergo THA through a same day discharge program respond with higher HCAHPS scores. Methods: Patients undergoing THA through our same day surgery (SDD) program at our institution from January 1, 2015, to September 2016 and completed HCAHPS surveys were compared to a cohort of patients who underwent THA as a standard inpatient and completed the HCAHPS survey during the same period. Electronic medical records were reviewed to obtain demographic data and improvement in validated patient reported outcomes measures. Results: Patientsin our SDD program were significantly more likely to rate the hospital as “top box” on eight of 11 HCAHPS domains. The remaining three domains that did not reach statistical significance all showed a trend toward increased likelihood of rating the hospital in the “top box” level. For willingness to recommend, 91% of SDD patients vs. 77% of non-SDD patients (p = 0.045) rated our hospital as “top box.” We had no significant difference between the groups in change from pre- to postoperative EQ-5D score or Hip Disability and Osteoarthritis Outcomes Score (HOOS). Conclusion: A same day surgery program can significantly improve patient satisfaction with THA as measured by the HCAHPS survey

The terminal overgrowth of the tibia following pediatric transtibial amputation is a common problem leading to pain, disability, and repeat surgical procedures. We present three patients who underwent transtibial amputation due to sarcoma of the lower extremity followed by compress osseointegration prosthesis fixation. The minimum follow-up was 1 year. The average age of patients was 10.8 years. There were no complications that required surgical revision. To date, there has been no evidence of terminal appositional overgrowth in this series. The application of an end-cap implant utilizing compressive osseointegration fixation can prevent terminal bone overgrowth in pediatric transtibial amputations

Musculoskeletal involvement occurs in approximately 25% of patients diagnosed with non-Hodgkin lymphoma (NHL). Skeletal involvement is typically secondary, with primary lymphoma of the bone being much rarer. We describe a case in which a 52-year-old man initially presented features suggestive of Lyme arthritis in his left knee. A synovial biopsy performed as part of a synovectomy procedure revealed a proliferative synovium with dense lymphoplasmacytic B cell infiltrate, suggestive of NHL. An inguinal lymph node biopsy was also performed but did not produce results pathologically similar to those of the left knee synovial biopsy.

Appendicular metastasis from multiple myeloma (MM) frequently presents with a pathologic fracture. In this case report, a patient with a long history of MM and an associated pathologic fracture was treated using a specialized brace. This orthosis uses a deforming element to asymmetrically increase the soft tissue pressure around the pathologic fracture. The patient experienced rapid pain relief and bony healing without surgical intervention.

Purpose: Untreated episodes of shoulder instability can have major consequences on athletic careers. Operative shoulder stabilization reduces the rate of recurrent instability and allows for high rates of return to sport (RTS). Basketball players who experience an episode of instability have high rates of recurrence, though little is known about postoperative player performance. The purpose of this study was to identify the impact of shoulder instability and surgical stabilization on player performance and career lengths in the National Basketball Association (NBA). Methods: NBA players who had episodes of shoulder instability between 1994-2014 were identified using the NBA Injury Surveillance and Analytics Database. Players were stratified according to operative versus nonoperative treatment of shoulder instability. Two demographic- and performance-matched controls were chosen for each test subject. Univariate analyses were used to compare pre- and postoperative player performance metrics. Survival analysis was used to assess the effect of shoulder surgery on postoperative career lengths. Results: Fifty athletes were identified, 46 (92.0%) returned to play in the NBA. Compared to controls, there was no significant difference in postoperative performance according to either 1- or 3-year averages. Survival analysis demonstrated no significant difference in postoperative career lengths between athletes with a history of shoulder surgery for instability and matched controls. Conclusion: NBA players return to professional basketball in high numbers following orthopedic surgery for shoulder instability. Shoulder instability may not be a career-altering event, as there are highly effective methods of shoulder stabilization available to athletes.

Eighty-five cases were included with 37 fractures treated by four fellowship trained adult traumatologists at a level I trauma center and 48 fractures treated by five fellowship trained pediatric orthopedists at a tertiary referral center. Radiographs were analyzed for Baumann’s angle and shaft-condylar angle, then statistical comparisons were performed to compare preoperative and postoperative measurements. Results: There was no difference in age, gender, laterality, fracture classification, use of medial pins, or neurovascular injuries between PO and AT (p > 0.05).

Patient outcomes using Knee injury and Osteoarthritis Outcome Score (KOOS) and visual analog scale (VAS) were recorded before undergoing HTO and compared with those recorded after a 2-year follow-up. Statistical analysis was performed using paired sample t-tests with p < 0.05 considered significant. Results: Twenty-three patients with mean age of 44.9 (± 8.48) were identified. The mean correction angle was 9.9° (range: 5° to 15°). Sixteen patients underwent a concomitant procedure. The average follow-up was 2 years (range: 2 to 3.5 years).

The remaining three domains that did not reach statistical significance all showed a trend toward increased likelihood of rating the hospital in the “top box” level. For willingness to recommend, 91% of SDD patients vs. 77% of non-SDD patients (p = 0.045) rated our hospital as “top box.” We had no significant difference between the groups in change from pre- to postoperative EQ-5D score or Hip Disability and Osteoarthritis Outcomes Score (HOOS). Conclusion: A same day surgery program can significantly improve patient satisfaction with THA as measured by the HCAHPS survey

The terminal overgrowth of the tibia following pediatric transtibial amputation is a common problem leading to pain, disability, and repeat surgical procedures. We present three patients who underwent transtibial amputation due to sarcoma of the lower extremity followed by compress osseointegration prosthesis fixation. The minimum follow-up was 1 year. The average age of patients was 10.8 years. There were no complications that required surgical revision. To date, there has been no evidence of terminal appositional overgrowth in this series. The application of an end-cap implant utilizing compressive osseointegration fixation can prevent terminal bone overgrowth in pediatric transtibial amputations

Musculoskeletal involvement occurs in approximately 25% of patients diagnosed with non-Hodgkin lymphoma (NHL). Skeletal involvement is typically secondary, with primary lymphoma of the bone being much rarer. We describe a case in which a 52-year-old man initially presented features suggestive of Lyme arthritis in his left knee. A synovial biopsy performed as part of a synovectomy procedure revealed a proliferative synovium with dense lymphoplasmacytic B cell infiltrate, suggestive of NHL. An inguinal lymph node biopsy was also performed but did not produce results pathologically similar to those of the left knee synovial biopsy.

Appendicular metastasis from multiple myeloma (MM) frequently presents with a pathologic fracture. In this case report, a patient with a long history of MM and an associated pathologic fracture was treated using a specialized brace. This orthosis uses a deforming element to asymmetrically increase the soft tissue pressure around the pathologic fracture. The patient experienced rapid pain relief and bony healing without surgical intervention.
