A Modification to the Brand Transfer for Claw Hand: The Four-Tailed Extensor Carpi Radialis Brevis to Lateral Band Transfer.

BACKGROUND: Claw deformity is a devastating consequence of low ulnar nerve palsy, resulting in loss of finger function. Traditionally, the Brand transfer is a favored intervention but requires lengthy grafts and bulky tenorrhaphies, risking adhesions in the lumbrical canal. We present a modified Brand tendon transfer, which extends the extensor carpi radialis brevis (ECRB) into 4 tails for individual grafting into the lateral band, decreasing adhesion risk and graft length need. METHODS: Nine consecutive patients with claw hand were examined in detail to confirm the diagnosis and appropriateness for claw-correction surgery by the senior author. All patients underwent our modified Brand transfer. Follow-up for a minimum of 6 months was pursued for each patient, with range of motion, grip strength, and pinch strength recorded at that time. RESULTS: Treated patients demonstrate maintained grip and pinch strength, coordinated grasp, and improvement in metacarpophalangeal posture. One patient required reoperation for extensive scarring and underwent tenolysis of the tendon grafts and revision grafting for the small finger. CONCLUSION: We concluded that our modified weave of a 4-tailed tendon graft through the ECRB is a synergistic transfer that maintains acceptable hand strength in the setting of a chronic low ulnar nerve palsy with a lower risk of tendon adhesion and length of grafting, offering an additional tool in the armamentarium of the hand surgeon approaching the ulnar nerve-injured hand.

The Role of Routine Pathologic Assessment After Pediatric Osteochondroma Excision.

BACKGROUND: Osteochondromas are benign osseous lesions often excised for pain, growth abnormalities, and aesthetic concerns. While characteristic clinical and radiographic features leave little diagnostic ambiguity in most cases of osteochondroma, pathologic analysis to confirm the diagnosis and screen for malignancy is routinely performed following surgical excision. The purpose of this study was to determine the clinical and economic value of routine pathologic analysis after osteochondroma excision in a pediatric population. METHODS: A retrospective review of clinical records from 2 pediatric orthopaedic hospitals (St. Louis Children's Hospital and Shriner's Hospital for Children, St. Louis) identified 426 osteochondroma lesions surgically resected from 201 patients. Patients with solitary and multiple lesions were included. Clinical, radiographic, and surgical data were recorded for each resection surgery. Pathologic reports were evaluated. Costs incurred for routine pathologic assessment was also noted. RESULTS: Totally, 132 patients were treated with surgical resection of a solitary osteochondroma lesion, while an additional 291 lesions were resected from 69 patients with multiple lesions. Average age at the time of surgical resection was 13.0 years (2.1 to 17.9). The most common anatomic locations of excised lesions included the distal femur (110, 25.8%), proximal tibia/fibula (95, 22.3%), and distal radius/ulna (58, 13.6%). All resected specimens were sent for pathologic analysis. The average size of the resected lesions was 19.9 mm3 (0.02 to 385.0 mm3). In all cases, the histologic diagnosis confirmed benign osteochondroma. The total charges of pathologic analysis including processing and interpretation fees was ∼$755.00 for each lesion assessed, for a total cohort charge of $321,630. CONCLUSION: We propose that in most cases of pediatric osteochondroma excision procedures, postoperative histologic analysis is not strictly indicated as it rarely, if ever, alters diagnosis or management. We suggest using a "gross only" analysis in these cases. However, we do believe that with preoperative diagnostic ambiguity, or if patients present with concerning features such as rapidly expansile lesions or cortical destruction, have axial skeleton or pelvic involvement, or enlarged cartilaginous caps, full histologic evaluation of the excised lesions will continue to be prudent. LEVEL OF EVIDENCE: Level IV-case series.

Opportunities for Increasing Diversity in Orthopaedics Through Virtual Mentorship Programs.

Orthopaedic surgery lags in recruiting women and under-represented minorities (URMs). In addition, women and URMs hold fewer leadership roles across orthopaedic subspecialties. This inequity is geographically heterogeneous, with female URM residents and attendings being more concentrated in some areas of the country. For instance, practicing female orthopaedic surgeons are more prevalent in Northeast and Pacific programs. Mentorship and representation in leadership positions play a notable role in trainee recruitment. Video communication platforms offer a novel mechanism to reach historically under-represented students across the country. We reviewed five established mentorship programs focused on women and URMs. Each program emphasized a longitudinal relationship between mentors and mentees. In reviewing these programs, we sought to identify the successful components of each program. Leveraging and integrating effective components already established by conventional mentorship programs into virtual programming will aid in optimizing those programs and improve geographic equity in access to mentorship resources. It is critical to extend the principles of successful mentorship programs to technology-enabled programs moving forward.

Thematic analysis of online discussion forums for soft tissue sarcomas.

BACKGROUND AND OBJECTIVES: As there is an increasing reliance on the internet for medical information, patients diagnosed with rare diseases have turned to online community forums to share information about their diagnoses. These forums help patients to gather and share information about their experience with disease. Additionally, these platforms enable patients to build unique connections based on their shared experiences. The objective of this study was to review shared posts in online community forums by individuals with soft tissue sarcomas to better understand commonly discussed themes. This information may improve the physicians' understanding of patients' concerns and feelings at the time of diagnosis and treatment. METHODS: We entered "sarcoma discussion forum" in search engines to identify internet discussion boards. Four major discussion forums were analyzed, and posts written between January 1, 2017 through May 1, 2022 addressing soft tissue sarcomas present in the upper and lower extremities were collected. Each post was analyzed by the two investigators in three steps (open coding, axial coding, and selective coding). RESULTS: A total of 506 posts were included in the final analysis. We used twenty-seven axial codes and four selective codes. Emotional Aspects/Connecting with Others was the most common theme (77 % of posts) followed by Information Support: Treatment (38 % of posts), Information Support: Diagnosis (24 % of posts) and Information Support: Recovery (21 % of posts). CONCLUSIONS: The most prevalent theme was centered on emotional aspects of these patients' journeys, highlighting the importance of providing resources to address emotional support for patients with soft tissue sarcoma and their families. LEVEL IV: Qualitative research study.

The low and disproportionate utilization of antiresorptive therapy in patients with osseous metastasis.

Introduction: Antiresorptive therapies are commonly utilized to mitigate and prevent skeletal-related-events in patients with metastatic osseous disease. However, limited data exists on the incidence or factors associated with prescription of antiresorptives or their effects on the incidence of pathologic fractures in patients with osseous metastatic disease. The aims of this study were to determine 1) the proportion of patients with osseous metastasis who receive antiresorptive therapy and sustain a pathologic fracture within 2-years of a new diagnosis, 2) factors associated with sustaining a pathologic fracture, and 3) factors are associated with the likelihood of receiving antiresorptive therapy. Methods: Between January 2010 and October 2021, 1,492,301 patients with a new diagnosis of osseous metastasis were captured in the Mariner dataset of the PearlDiver database. Patients were identified using International Classification of Disease (ICD) 10 codes for osseous metastasis. We excluded patients with a prior diagnosis of osseous metastasis and if they had less than two-years of follow-up. There were 696,459 patients (46.7 %) included for analysis. Of these patients, 63 % (N = 437,716) were over the age of 65, 46 % were women, and 5.6 % had Medicaid insurance. We identified patients who were prescribed antiresorptive therapy within 2-years of a new diagnosis of osseous metastasis. Cox proportional hazard ratio models were created to predict factors associated with 1) pathologic fracture and 2) receiving antiresorptive therapy within 2-years of a new diagnosis of osseous metastasis, respectively. Results: The incidence of antiresorptive therapy prescription was 7.7 % in our cohort. The incidence of pathologic fracture within 2-years of a new diagnosis was 7.3 %. The risk of sustaining a pathologic fracture was higher for patients aged 35-44 (HR 1.27 [95 % CI 1.08-1.51]; p = 0.004), those with primary kidney cancer (HR 1.78 [95 % CI 1.71-1.85]; p < 0.001), p = 0.005), multiple myeloma (HR 2.49 [95 % CI 2.39-2.59]; p < 0.001), and Medicaid insurance (HR 1.17 [95 % CI 1.13-1.21]; p < 0.001). The risk of sustaining a pathologic fracture was lower for patients on antiresorptive therapy (HR 0.71 [95 % CI 0.66-0.83]; p < 0.001). Increasing age was an independent predictor for antiresorptive therapy prescription (HR 1.77-16.38, all p < 0.05). Male sex as well as diagnosis of primary prostate, lung, or kidney cancer and Medicaid insurance were negative predictors for antiresorptive prescription (HR 0.15-0.87, all p < 0.001). Conclusions: The utilization of antiresorptive therapy in patients with osseous metastases remains unacceptably low, with only 7.7% patients being prescribed these therapies, despite shown efficacy in reduction of pathologic fractures incidences. This study identified younger patients, males, and those diagnosed with primary prostate, kidney, and lung cancers to be at increased risk of not being prescribed antiresorptive therapy, suggesting possible bias in prescription patterns. Greater efforts are needed by providers who care for this vulnerable population to increase the utilization and reduce disparities of prescribing antiresorptive therapy.

Approach to the Treatment of Expansile Metacarpal Aneurysmal Bone Cysts: A Report of Two Cases.

The two cases presented demonstrate the management of aneurysmal bone cysts of the metacarpal, which destroyed the normal bone architecture. Treatment of both cases included wide resection and metacarpal reconstruction with an intercalary fibular allograft. Denosumab use contrasts these two cases and is helpful in reestablishment of a cortical rim for fixation in the absence of a 1-cm margin proximally or distally to preserve the native carpometacarpal and metacarpophalangeal joints. Surgical resection and allograft reconstruction is a viable treatment for expansile metacarpal aneurysmal bone cysts, and neoadjuvant denosumab has utility in creating an ossified margin for fixation.

The microbial profile of infected endoprosthetic reconstructions after wide excision for patients with musculoskeletal tumors: A call for pathogen-based practices.

BACKGROUND AND OBJECTIVES: Periprosthetic infection is a devastating complication following endoprosthetic reconstruction. This study utilized a large database of endoprostheses to describe the incidence, risk factors, and microbial profile of such infections to better catalogue and understand these catastrophic events. METHODS: A retrospective review of endoprosthetic reconstructions for an oncologic indication from January 1, 1981 to December 31, 2020 was performed. Demographic, oncologic, procedural and outcome data was analyzed. Multivariable logistic regression was used to identify potential risk factors for infection with significance defined as p < 0.05. RESULTS: Forty four out of 712 (6.2%) reconstructions resulted in infection at a mean time of 39.9 ± 44.5 months. Revision surgery (odds ratio [OR] 6.14, p < 0.001) or having a postoperative wound complication (OR 7.67, p < 0.001) were significantly associated with infection. Staphylococcus aureus and Staphylococcus epidermidis were the most commonly cultured organisms at a rate of 34.1% (15/44) and 22.7% (10/44), respectively. Ten infections resulted in amputation; five due to antimicrobial-resistant infections and three due to polymicrobial infections. CONCLUSION: Understanding the microbial profile of patients undergoing endoprosthetic reconstruction is paramount. This study demonstrates a relatively high rate of polymicrobial and antibiotic-resistant infections that portend worse outcomes, thus suggesting that pathogen-specific infectious practices may be warranted. LEVEL OF EVIDENCE: Retrospective cohort study, level III.

Scapholunate Instability: Diagnosis and Management - Classification and Treatment Considerations - Part 2.

Intervention for scapholunate instability is aimed at halting the degenerative process by restoring ligament integrity and normalizing carpal kinematics. Part 1 of this Current Concepts article reviewed the anatomy, kinematics, and biomechanical properties of the scapholunate ligament as well as its critical stabilizers. In this section, we provide a foundation for understanding the spectrum of scapholunate ligament instability and incorporate meaningful new anatomical insights that influence treatment considerations. These updates clarify the importance of the critical stabilizers of the scapholunate interval, ligament-specific considerations in scapholunate ligament reconstruction, and the risks of ligament disinsertion when surgically exposing the dorsal wrist. We propose a ligament-based treatment algorithm based on the stage of injury, degree and nature of ligament damage, and presence of arthritic changes.

Risk Factors for All-Cause Early Reoperation Following Tumor Resection and Endoprosthetic Reconstruction: A Secondary Analysis from the PARITY Trial.

BACKGROUND: Oncologic resection and endoprosthetic reconstruction of lower-extremity musculoskeletal tumors are complex procedures fraught with multiple modes of failure. A robust assessment of factors contributing to early reoperation in this population has not been performed in a large prospective cohort. The aim of the present study was to assess risk factors for early reoperation in patients who underwent tumor excision and endoprosthetic reconstruction, with use of data from the Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial. METHODS: Baseline characteristics were assessed, including age, sex, tumor type, tumor location, presence of a soft-tissue mass, diabetes, smoking status, chemotherapy use, and neutropenia. Operative factors were recorded, including operative time, topical antibiotics, silver-coated prosthetics, endoprosthetic fixation, extra-articular resection, length of bone resected, margins, tranexamic acid, postoperative antibiotics, negative-pressure wound therapy, and length of stay. Univariate analysis was utilized to explore the differences between patients who did and did not undergo reoperation within 1 year postoperatively, and a multivariate Cox proportional hazards regression model was utilized to explore the predictors of reoperation within 1 year. RESULTS: A total of 155 (25.7%) of 604 patients underwent ≥1 reoperation. In univariate analysis, tumor type (p < 0.001), presence of a soft-tissue mass (p = 0.045), operative time (p < 0.001), use of negative-pressure wound therapy (p = 0.010), and hospital length of stay (p < 0.001) were all significantly associated with reoperation. On multivariate assessment, tumor type (benign aggressive bone tumor versus primary bone malignancy; hazard ratio [HR], 0.15; 95% confidence interval [CI], 0.04 to 0.63; p = 0.01), operative time (HR per hour, 1.15; 95% CI, 1.10 to 1.23; p < 0.001), and use of negative-pressure wound therapy (HR, 1.93; 95% CI, 1.30 to 2.90; p = 0.002) remained significant predictors of reoperation within 1 year. CONCLUSIONS: Independent variables associated with reoperation within 1 year in patients who underwent tumor resection and endoprosthetic reconstruction included tumor type (benign aggressive bone tumor versus primary bone malignancy), operative time, and use of negative-pressure wound therapy. These results will help to inform patients and surgeons regarding the risk of reoperation by diagnosis and reinforce operative time as a factor influencing reoperation. These results also support further investigation into the use of negative-pressure wound therapy at the time of surgery in this patient population. LEVEL OF EVIDENCE: Therapeutic Level II.

Most Patients With Bone Sarcomas Seek Emotional Support and Information About Other Patients' Experiences: A Thematic Analysis.

BACKGROUND: Online discussion forums allow individuals who otherwise may be strangers to create a community where they can seek and share information. Patients with bone sarcomas and their support networks use discussion forums dedicated to cancer support. There is a paucity of published reports regarding the care experience of patients with bone sarcomas because studies on online discussion groups have primarily focused on some of the more common cancers, including breast and prostate cancer. Understanding commonly discussed themes among patients with bone sarcomas would allow treating physicians to have a better understanding of patient concerns when providing patient education and counseling. QUESTION/PURPOSE: We performed this study to review posts from bone sarcoma internet discussion boards to establish common themes related to the care experience of patients with sarcomas. METHODS: Online discussion forums were identified using the search term "sarcoma discussion forum." After identifying 12 websites, we excluded closed forum groups, websites with missing or invalid links to forums, and nonpublic forums, such as groups on Facebook. These websites include profiles and photos that are personal, and sufficient author anonymity could not be achieved for this study. Posts written between January 1, 2012, and May 1, 2022, posted on five discussion boards were reviewed and collected until we reached a point of data saturation in which we agreed that the collection of additional posts would not reveal new themes. Discussion threads were filtered to identify posts pertaining to the most common bone sarcomas: chondrosarcoma, Ewing sarcoma, and osteosarcoma. Grounded theory-the methodology of repeated analyses of qualitative data to identify recurring themes or concepts-was used to analyze posts. Caregiver posts were delineated from patient posts and categorized separately for subgroup analysis. Grounded theory, although a qualitative method, endeavors to integrate the strengths inherent in quantitative methods with qualitative approaches. Grounded theory categorizes words, language, and the meanings these imply and seeks to organize and reduce the data gathered into themes or essences, which, in turn, can be fed into descriptions, models, or theories. Our analysis used three reviews of text to assign and group codes based on repeating ideas or concepts. The first review (open coding) aims to assign codes based on the verbatim text included by the author to capture the specific thoughts and ideas of the post. The second review (axial coding) aims to consolidate the ideas of posts by applying broader concepts to each post. The third and final review (selective coding) aims to further consolidate the themes of each post by trying to embody the main message contained in a post. A total of 570 posts from 139 threads were collected and analyzed using grounded theory. Twenty-five axial codes and four selective codes were created. We defined data saturation by the absence of a new open code in the analysis of a block of 50 posts to ensure that signals of saturation were not accepted too early in the analysis. RESULTS: The four selective codes included emotional aspects or connecting with others, information support: diagnosis, information support: treatment, and information support: recovery. Of these four codes, emotional aspects and connecting with others was the most prevalent theme (78% [445 of 570] of posts) followed by information support: treatment (49% [282 of 570] of posts). Information support: diagnosis and information support: recovery were each captured in 15% of posts. CONCLUSION: Analysis of posts reveals that the two most common themes involve seeking out emotional support and information about the experiences of others with various treatment modalities. Although most of the posts we assessed contained experiential information and emotional support rather than directed medical advice, future studies should assess the accuracy of information shared among online sarcoma forums. CLINICAL RELEVANCE: Physicians caring for patients with sarcomas should not only address patient concerns related to medical care, but also provide emotional support directly and assist patients by providing resources to peer support outlets, including online discussion forums. Although we cannot ascertain the proportion of patients who use online sites given the anonymity of posts included, these findings suggest common experiential themes across patients with sarcomas outside their doctors' offices. It is important that providers be aware of reputable forums to provide as resources for their patients. The Musculoskeletal Tumor Society may further benefit from endorsing one or more of these forums and providing physician oversight to monitor misinformation.

Proximal Femur Replacements for an Oncologic Indication Offer a Durable Endoprosthetic Reconstruction Option: A 40-year Experience.

BACKGROUND: Proximal femur replacements (PFRs) are an effective surgical option to treat primary and metastatic tumors causing large bony defects in the proximal femur. Given the relative rarity of these indications, current studies on PFR for oncologic indications are generally limited by patient volume or relatively short-term follow-up. Because recent advances in systemic therapy have improved the prognosis of patients who undergo limb salvage surgery for musculoskeletal tumors, data on the long-term durability of endoprosthetic reconstructions have become increasingly important. QUESTIONS/PURPOSES: (1) How does the long-term survival of cemented bipolar PFRs compare with patient survival in patients who underwent PFR for benign, aggressive, and metastatic tumors? (2) What are common reasons for revisions of primary PFRs? (3) Which factors are associated with survival of primary PFRs? (4) What is the survivorship free from conversion of bipolar PFRs to THA? METHODS: Between January 1, 1980, and December 31, 2020, we treated 812 patients with an endoprosthetic reconstruction for an oncologic indication. All patients who underwent a primary PFR for an oncologic indication were included in this study. The study cohort consisted of 122 patients receiving a primary PFR. Eighteen patients did not reach a censored endpoint such as death, revision, or amputation within 2 years. Thirty-three patients died within 2 years of their surgery. Of the 122 patients with primary PFRs, 39 did not reach a censored endpoint and have not been seen within the past 5 years. However, the mean follow-up time for these patients was longer than 10 years. The Social Security Death Index was queried to identify any patients who may have died but might not have been captured by our database To allow for adequate follow-up, endoprosthetic reconstructions performed after December 31, 2020 were excluded. The mean age at the time of the index surgery was 48 ± 22 years. The mean follow-up time of surviving patients was 7 ± 8 years. All PFRs were performed using a bipolar hemiarthroplasty with a cemented stem, and all implants were considered comparable. Demographic, oncologic, procedural, and outcome data including prosthesis survival, patient survival, complication rates, and rates of conversion to THA were analyzed. Patient, prosthesis, and limb salvage survival rates were generated, with implant revision as the endpoint and death as a competing risk. Statistical significance was defined as p < 0.05. RESULTS: Generally, patients with benign or low-grade (Stage I) disease outlived their implants (100% patient survival through 30 years; p = 0.02), whereas the opposite was true in patients with high-grade, localized Stage II disease (64% patient survival at 5 years [95% CI 49% to 76%]; p = 0.001) or widespread Stage III metastatic disease (6.2% patient survival at 5 years [95% CI 0.5% to 24%]; p < 0.001). Primary PFR implant survival at 5, 10, 20, and 30 years was 97% (95% CI 90% to 99%), 81% (95% CI 67% to 90%), 69% (95% CI 46% to 84%), and 51% (95% CI 24% to 73%), respectively. Eight percent (10 of 122) of primary PFRs were revised for any reason. The most common causes of revision were aseptic loosening (3% [four of 122]), infection (3% [three of 122]), breakage of the implant (2% [two of 122]), and tumor progression (1% [one of 122]). Follow-up time was the only factor that was associated with revision of primary PFRs. Neither segment length nor stem length were associated with revision of primary. Six percent (seven of 122) of PFRs were converted to THA at a mean 15 ± 8 years from the index procedure. Survivorship free from conversion to THA (accounting for death as a competing risk) was 94% (95% CI 85% to 99%), 86% (95% CI 68% to 94%). and 77% (95% CI 51% to 91%) at 10, 20, and 30 years, respectively. CONCLUSION: Cemented bipolar PFRs for an oncologic indication are a relatively durable reconstruction technique. Given the relative longevity and efficacy of PFRs demonstrated in our study, especially in patients with high-grade or metastatic disease where implant survival until all-cause revision was longer than patient survival, surgeons should continue to seriously consider PFRs in appropriate patients. The relative rarity of these reconstructions limits the number of patients in this study as well as in current research; thus, further multi-institutional collaborations are needed to provide the most accurate prognostic data for our patients. LEVEL OF EVIDENCE: Level III, therapeutic study.

Scapholunate Instability: Diagnosis and Management - Anatomy, Kinematics, and Clinical Assessment - Part I.

Injuries to the scapholunate joint are the most frequent cause of carpal instability. The sequelae of these injuries account for considerable morbidity, and if left untreated, may lead to scapholunate advanced collapse and progressive deterioration of the carpus. Rupture of the scapholunate interosseous ligament and its critical stabilizers causes dyssynchronous motion between the scaphoid and lunate. Additional ligament injury or attenuation leads to rotary subluxation of the scaphoid and increased scapholunate gap. Intervention for scapholunate instability is aimed at halting the degenerative process by restoring ligament integrity and normalizing carpal kinematics. In the first section of this review, we discuss the anatomy, kinematics, and biomechanical properties of the scapholunate ligament as well as its critical ligament stabilizers. We provide a foundation for understanding the spectrum of scapholunate ligament instability and incorporate meaningful new anatomical insights that influence treatment considerations. The purpose is to provide an update regarding the anatomy of the scapholunate ligament complex, importance of the critical ligament stabilizers of the proximal carpal row, introduction of safe technique to surgically expose the scaphoid and lunate, as well as pathoanatomy as it pertains to the treatment of scapholunate dissociation. In the second section of this review, we propose a novel ligament-based treatment algorithm based on the stage of injury, degree and nature of ligament damage, and presence of arthritic changes.

Assessing Gender Differences in Technical Skills and Confidence in Orthopaedic Surgery Residency Applicants.

INTRODUCTION: Variations in confidence for procedural skills have been demonstrated when comparing male and female medical students in surgical training. This study investigates whether differences in technical skill and self-reported confidence exist between male and female medical students applying to orthopaedic residency. METHODS: All medical students (2017 to 2020) invited to interview at a single orthopaedic residency program were prospectively evaluated on their technical skills and self-reported confidence. Objective evaluation of technical skill included scores for a suturing task as evaluated by faculty graders. Self-reported confidence in technical skills was assessed before and after completing the assigned task. Scores for male and female students were compared by age, self-identified race/ethnicity, number of publications at the time of application, athletic background, and US Medical Licensing Examination Step 1 score. RESULTS: Two hundred sixteen medical students were interviewed, of which 73% were male (n = 158). No gender differences were observed in suture task technical skill scores or mean difference in simultaneous visual task scores. The mean change from pre-task and post-task self-reported confidence scores was similar between sexes. Although female students trended toward lower post-task self-reported confidence scores compared with male students, this did not achieve statistical significance. Lower self-reported confidence was associated with a higher US Medical Licensing Examination score and with attending a private medical school. DISCUSSION: No difference in technical skill or confidence was found between male and female applicants to a single orthopaedic surgery residency program. Female applicants trended toward self-reporting lower confidence than male applicants in post-task evaluations. Differences in confidence have been shown previously in surgical trainees, which may suggest that differences in skill and confidence may develop during residency training.

Social determinants of health and race are independent predictors of reduced rotator cuff surgery rates in the Medicare population.

BACKGROUND: Racial disparities have been shown to influence rates of surgery for patients with rotator cuff disease. Some individuals have attributed adverse social determinants of health (SDOHs) as potential confounders of this relationship between race and surgery rate. However, there is a paucity of literature observing whether adverse SDOHs and race independently influence rotator cuff surgery rates. Therefore, the purpose of this study was to determine whether adverse SDOHs and race are independent predictors of rotator cuff surgery rates for Medicare beneficiaries. METHODS: A retrospective analysis was conducting using the Medicare Standard Analytic Files (SAF) data set of the PearlDiver database, observing 211,340 patients with rotator cuff pathology. Univariate and multivariable regression analyses were performed to observe whether race and adverse SDOHs were independent variables associated with rotator cuff surgery rates. To determine whether adverse SDOHs significantly influenced racial disparities, stratified analyses of patients with ≥1 adverse SDOH and those without adverse SDOHs were conducted to compare the odds ratios (ORs) and 95% confidence intervals (CIs) of racial disparities. RESULTS: Among patients with rotator cuff disease, 21,679 (10.26%) were of nonwhite race and 21,835 (10.33%) had ≥1 adverse SDOH. The variables of nonwhite race (OR, 0.622; 95% CI, 0.599-0.668; P < .001) and having ≥1 adverse SDOH (OR, 0.715; 95% CI, 0.501-0.814; P < .001) were independent predictors of not undergoing surgery. On stratified analysis, there was no significant difference in racial disparities in patients with ≥1 adverse SDOH (OR, 0.620; 95% CI, 0.440-0.875) and those without adverse SDOHs (0.635; 95% CI, 0.601-0.671) based on overlapping 95% CIs. DISCUSSION: This study demonstrated that among Medicare beneficiaries, adverse SDOHs and race are independent predictors of lower rotator cuff surgery rates, emphasizing the need to address disparities based on race alone.

The Role of Denosumab in the Treatment of Primary Tumors of Bone.

Many hand surgeons treat benign bone tumors without referral to orthopedic oncologists. However, there have been considerable advances in medical therapy for some of these tumors, with which hand surgeons may not be as familiar. This review focuses on the mechanism and uses of denosumab in the treatment of benign tumors of bone. Although the hand surgeon may not be directly prescribing this therapy, they are often the only physician treating the patient for these conditions. As such, awareness regarding the use of this therapy in reducing pain, decreasing tumor volume, and treatment of potential lung metastases is critical to those taking on these cases without the support of an orthopedic oncologist. This article aims to familiarize hand surgeons with denosumab to help promote knowledge of this therapeutic option and the potential role of this medication in the treatment of primary bone tumors in the hand.

What are the indications and survivorship of tumor endoprosthetic reconstructions for patients with extremity metastatic bone disease?

BACKGROUND AND OBJECTIVES: Given advances in therapies, endoprosthetic reconstruction (EPR) in metastatic bone disease (MBD) may be increasingly indicated. The objectives were to review the indications, and implant and patient survivorship in patients undergoing EPR for MBD. METHODS: A review of patients undergoing EPR for extremity MBD between 1992 and 2022 at two centers was performed. Surgical data, implant survival, patient survival, and implant failure modes were examined. RESULTS: One hundred fifteen patients were included with a median follow-up of 14.9 months (95% confidence interval [CI]: 9.2-19.3) and survival of 19.4 months (95% CI: 13.6-26.1). The most common diagnosis was renal cell carcinoma (34/115, 29.6%) and the most common location was proximal femur (43/115, 37.4%). Indications included: actualized fracture (58/115, 50.4%), impending fracture (30/115, 26.1%), and failed fixation (27/115, 23.5%). Implant failure was uncommon (10/115, 8.7%). Patients undergoing EPR for failed fixation were more likely to have renal or lung cancer (p = 0.006). CONCLUSIONS: EPRs were performed most frequently for renal cell carcinoma and in patients with a relatively favorable survival. EPR was indicated for failed previous fixation in 23.5% of cases, emphasizing the importance of predictive survival modeling. EPR can be a reliable and durable surgical option for patients with MBD.

Incidence of Trigger Finger in Surgically and Nonsurgically Managed Carpal Tunnel Syndrome.

Purpose: The purpose of this study was to determine whether extremities undergoing carpal tunnel release (CTR) have an increased rate of trigger finger (TF) compared with conservatively managed carpal tunnel syndrome. Methods: Data were collected from the Humana Insurance Database, and subjects were chosen on the basis of a history of CTR with propensity matching performed to develop a nonsurgical cohort. Following propensity matching, 16,768 patients were identified and equally split between surgical and nonsurgical treatments. Demographic information and medical comorbidities were recorded. Univariate and multivariate analyses were performed to identify risk factors for the development of TF within 6 months of carpal tunnel syndrome diagnosis. Results: Patients in the surgical cohort were more likely to develop TF than those in the nonsurgical cohort whether in the ipsilateral or contralateral extremity. Whether managed surgically or nonsurgically, extremities with carpal tunnel syndrome demonstrated an increased prevalence of TF than their contralateral, unaffected extremity. Conclusions: Surgeons should be aware of the association of TF and CTR both during the presurgical and postsurgical evaluations as they might impact patient management. With knowledge of these data, surgeons may be more attuned to detecting an early TF during the postsurgical period and offer more aggressive treatment of TF pathology during CTR. Type of study/level of evidence: Prognostic III.

Boston Carpal Tunnel Questionnaire Scores Alone Do Not Predict Surgical Intervention for Patients With Carpal Tunnel Syndrome.

BACKGROUND: With the expanded indications for telemedicine, there is increased utility for screening methods to determine which patients are likely to progress to surgical intervention, requiring in-person visits. Patient-rated tools such as the Boston Carpal Tunnel Questionnaire (BCTQ) may be one such tool for screening patients with carpal tunnel syndrome (CTS). The aim of the study was to evaluate whether BCTQ scores were predictive of offering conservative treatment or surgical intervention for CTS. METHODS: Patients diagnosed with CTS from January 2017 to February 2020 completed BCTQ questionnaires prior to in-person office visits. Demographics, comorbidities, and highest level of intervention recommended were recorded for each patient as conservative, injection, or surgery. Pearson χ2 and independent-samples t tests were conducted to determine whether BCTQ symptom severity and functional scores were associated with intervention type. RESULTS: A total of 200 patients with CTS were included. Of these, 103 were recommended conservative or injection treatment and 97 were recommended surgery. There were no differences in comorbidities between groups, including other upper extremity pathology (P = .57), previous upper extremity surgery (P = .32), hypertension (P = .17), hypothyroidism (P = .15), rheumatoid arthritis (P = .34), and diabetes (P = .30). Between these groups, there were no differences in BCTQ symptom severity score (symptom severity scale [SSS]; P = .16) or BCTQ functional severity score (functional severity scale [FSS]; P = .96). CONCLUSIONS: There is no correlation between comorbidities and BCTQ SSS or FSS score, and offering surgery for CTS. In an era of minimizing non-essential health care visits, the BCTQ is insufficient in screening patients as potential surgical candidates.

Impact of Patient and Tumor Characteristics on Range of Motion and Recurrence Following Treatment of Enchondromas of the Hand.

PURPOSE: The approach to the treatment of enchondromas of the hand is varied, and there is no clear consensus on graft source, fixation, or need for intraoperative adjuvant therapy. We reviewed a cohort of patients who underwent curettage and bone grafting with cancellous allograft chips without internal fixation or adjuvant therapy and reported on postoperative range of motion (ROM) and recurrence rates. METHODS: We performed a retrospective review of patients who underwent surgical treatment for hand enchondroma over a 23-year period. We collected information on demographics and presenting enchondroma characteristics, including Takigawa classification and presence of pathologic fracture or associated syndromes. Patients were treated with open biopsy with curettage and grafting with cancellous allograft chips. Postoperative ROM, complications, and recurrences were recorded. RESULTS: Our series included 111 enchondromas in 104 patients. Seventeen of 104 patients (16%) had a diagnosis of Ollier disease. Average length of follow-up was 3.1 years. Eighty-one percent of patients achieved full ROM. Treatment of patients who presented with preoperative pathologic fracture resulted in a greater frequency of reduced postoperative ROM at 28% (9/32) compared to 15% (11/72) of those patients who did not present with preoperative pathologic fracture. Local recurrence developed in 5 of 50 (10%) patients with a minimum of 2 years of follow-up. Local recurrence occurred at higher-than-average rates in patients with giant form Takigawa classification (43%, 3/7) and Ollier disease (23%, 3/13). CONCLUSIONS: Treatment of enchondromas with biopsy, curettage, and allograft results in full ROM in 81% of patients. Patients with preoperative pathologic fracture should be advised of a greater risk of postoperative extension deficit. Recurrence remains rare and is associated with syndromic presentation and giant form lesions. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Anticoagulant Usage After Anterior Cruciate Ligament Reconstruction Is Associated With Increased Rate of Manipulation Under Anesthesia.

BACKGROUND: Arthrofibrosis after anterior cruciate ligament reconstruction (ACLR) is a notable but uncommon complication of ACLR. To improve range of motion after ACLR, aggressive physical therapy, arthroscopic/open lysis of adhesions, and revision surgery are currently used. Manipulation under anesthesia (MUA) is also a reasonable choice for an appropriate subset of patients with inadequate range of motion after ACLR. Recently, the correlation between anticoagulant usage and arthrofibrosis after total knee arthroplasty has become an area of interest. The purpose of this study was to determine whether anticoagulant use has a similar effect on the incidence of MUA after ACLR. METHODS: The Mariner data set of the PearlDiver database was used to conduct this retrospective cohort study. Patients with an isolated ACLR were identified by using Current Procedural Terminology codes. Patients were then stratified by MUA within 2 years of ACLR, and the use of postoperative anticoagulation was identified. In addition, patient demographics, medical comorbidities, and timing of ACLR were recorded. Univariate and multivariable analyses were used to model independent risk factors for MUA. RESULTS: We identified 216,147 patients who underwent isolated ACLR. Of these patients, 3,494 (1.62%) underwent MUA within 2 years. Patients who were on anticoagulants after ACLR were more likely to require an MUA (odds ratio [OR]: 2.181; P < 0.001), specifically low-molecular-weight heparin (OR: 2.651; P < 0.001), warfarin (OR: 1.529; P < 0.001), and direct factor Xa inhibitors (OR: 1.957; P < 0.001). DISCUSSION: In conclusion, arthrofibrosis after ACLR is associated with the use of preoperative or postoperative thromboprophylaxis. Healthcare providers should be aware of increased stiffness among these patients and treat them aggressively.
