Objective: Accurate determination of life expectancy becomes very important when determining the treatment of patients with pathologic fractures. We aimed to investigate the predictive role of the PATHFx model in Turkish patients by estimating the area under curve (AUC) of the receiver operator characteristic (ROC) and externally validating the results of PATHFx on the Turkish population. Methods: The data of 122 patients who presented to one of four orthopaedic oncology referral centres in Istanbul (2010-2017) and underwent surgical management of pathologic fractures were retrospectively collected. Patients were evaluated according to age, sex, type of pathologic fracture, presence of organ metastasis, presence of lymph node metastasis, haemoglobin concentration at presentation, primary oncologic diagnosis, number of bone metastases, and Eastern Cooperative Oncology Group (ECOG) status. Estimations of the PATHFx program by months were statistically evaluated using ROC analysis. Results: In our study population (122 patients), all survived the first month, 102 survived the third month, 89 were alive at 6 months, and 58 patients survived at 12 months. At 18 and 24 months, 39 and 27 patients were alive, respectively. The AUC value was 0.677 at 3 months, 0.695 at 6 months, 0.69 at 12 months, 0.674 at 18 months, and 0.693 at 24 months. The 3-, 6-, 12-, 18-, and 24-month survival rates were statistically significant (P < 0.01 and P < 0.05). ECOG performance status was 0-2 points in 33 patients (Memorial Sloan-Kettering Cancer Center (MSKCC) data set: 93 cases, our data set: 33 cases). ECOG performance status was 3-4 points in 89 patients (MSKCC data set: 96 cases, our data set: 89 cases). Conclusions: The objective data used by PATHFx for prediction provided statistically accurate estimates on Turkish patients, who are presumed to have mixed genomes through history from both Europe and Asia, and demonstrates its applicability to the Turkish population.

Background: We sought to assess whether select domains of the Patient-Reported Outcomes Measurement Information System (PROMIS) significantly correlate with the Disabilities of the Arm, Shoulder, and Hand (DASH) score and the Defense and Veterans Pain Rating Scale (DVPRS) among transhumeral amputees. Methods: We prospectively administered DASH, DVPRS, and PROMIS (including Upper Extremity, Pain Interference, and Pain Behavior domains) testing to patients presenting for consideration of osseointegration after transhumeral amputation. Concurrent validity was assessed via Pearson correlation testing. Results: The mean DASH score of the cohort was 32.8. The mean DVPRS score was 1.8. The mean PROMIS scores were 33.8, 50.5, and 50.6 for Upper Extremity, Pain Interference, and Pain Behavior domains, respectively. Pearson testing demonstrated a significant, inverse correlation between DASH and PROMIS Upper Extremity scores (r = −0.85, P =.002). There was also significant correlation between DVPRS and PROMIS Pain Interference scores (r = 0.69, P =.03). The PROMIS Pain Behavior domain did not significantly correlate with either DASH or DVPRS. Conclusions: Patient-Reported Outcomes Measurement Information System Upper Extremity and Pain Interference scores demonstrated significant concurrent validity with traditional measures (DASH and DVPRS) of patient-reported outcome in our population of transhumeral amputees.

Background: Patients with complex polytrauma in the military and civilian settings are often exposed to substantial diagnostic medical radiation because of serial imaging studies for injury diagnosis and subsequent management. This cumulative radiation exposure may increase the risk of subsequent malignancy. This is particularly true for combat-injured servicemembers who receive care at a variety of facilities worldwide. Currently, there is no coordinated effort to track the amount of radiation exposure each servicemember receives, nor a surveillance program to follow such patients in the long term. It is important to assess whether military servicemembers are exposed to excessive diagnostic radiation to mitigate or prevent such occurrences and monitor for carcinogenesis, when necessary. The cumulative amount of radiation exposure for combat-wounded and noncombat-wounded servicemembers has not been described, and it remains unknown whether diagnostic radiation exposure meets thresholds for an increased risk of carcinogenesis. Questions/purposes: We performed this study to (1) quantify the amount of exposure for combat-wounded servicemembers based on medical imaging in the first year after injury and compare those exposures with noncombat-related trauma, and (2) determine whether the cumulative dose of radiation correlates to the Injury Severity Score (ISS) across the combat-wounded and noncombat-wounded population combined. Methods: We performed a retrospective study of servicemembers who sustained combat or noncombat trauma and were treated at Walter Reed National Military Medical Center from 2005 to 2018. We evaluated patients using the Department of Defense Trauma Registry. After consolidating redundant records, the dataset included 3812 unique servicemember encounters. Three percent (104 of 3812) were excluded because of missing radiation exposure data in the electronic medical record. The final cohort included 3708 servicemembers who had combat or noncombat injury trauma, with a mean age at the time of injury of 26 ± 6 years and a mean ISS of 18 ± 12. The most common combat trauma mechanisms of injury were blast (in 65% [2415 of 3708 patients]), followed by high-velocity gunshot wounds (in 22% [815 of 3708 patients]). We calculated the cumulative diagnostic radiation dose exposure at 1 year post-traumatic injury in patients with combat-related trauma and those with noncombat trauma. We did this by multiplying the number of imaging studies by the standardized effective radiation dose for each imaging study type. We then performed analysis of variance for four data subsets (battle combat trauma, nonbattle civilian trauma, high ISS, and high radiation exposure [> 50 mSv]) independently. To evaluate whether the total number of imaging studies, radiation exposure, and ISS values differed between battle-wounded and nonbattle-wounded patients, we performed a pairwise t-test. Results: The mean radiation exposure for combat-related injuries was 35 ± 26 mSv while the mean radiation exposure for noncombat-related injuries was 22 ± 33 mSv in the first year after injury. In the first year after trauma, 44% of patients (1626 of 3708) were exposed to high levels of radiation that were greater than 20 mSv, and 23% (840 of 3708) were exposed to very high levels of radiation that were greater than 50 mSv. Servicemembers with combat trauma-related injuries had eight more imaging studies than those who sustained noncombat injuries. Servicemembers with combat trauma injuries (35 ± 26 mSv) were exposed to more radiation (approximately 4 mSv) than patients treated for noncombat injuries (22 ± 33 mSv) (p = 0.01). We found that servicemembers with combat injuries had a higher ISS than servicemembers with noncombat trauma (p < 0.001). We found a positive correlation between radiation exposure and ISS for servicemembers. The positive relationship between radiation exposure and ISS held for combat trauma (r2 = 0.24; p < 0.001), noncombat trauma (r2 = 0.20; p < 0.001), servicemembers with a high ISS (r2 = 0.10; p < 0.001), and servicemembers exposed to high doses of radiation (r2 = 0.09; p < 0.001). Conclusion: These data should be used during clinical decision-making and patient counseling at military treatment facilities and might provide guidance to the Defense Health Agency. These recommendations will help determine whether the benefits of further imaging outweigh the risk of carcinogenesis. If not, we need to develop interdisciplinary clinical practice guidelines to reduce or minimize radiation exposure. It is important for treating physicians to seriously weigh the risk and benefits of every imaging study ordered because each test does not come without a cumulative risk.

Background: Pathologic fracture of the long bones is a common complication of bone metastases. Intramedullary nail stabilization can be used prophylactically (for impending fractures) or therapeutically (for completed fractures) to preserve mobility and quality of life. However, local disease progression may occur after such treatment, and there is concern that surgical instrumentation and the intramedullary nail itself may seed tumor cells along the intramedullary tract, ultimately leading to loss of structural integrity of the construct. Identifying factors associated with local disease progression after intramedullary nail stabilization would help surgeons predict which patients may benefit from alternative surgical strategies.Questions/purposes: (1) Among patients who underwent intramedullary nail stabilization for impending or completed pathologic fractures of the long bones, what is the risk of local progression, including progression of the existing lesion and development of a new lesion around the nail? (2) Among patients who experience local progression, what proportion undergo reoperation? (3) What patient characteristics and treatment factors are associated with postoperative local progression? (4) What is the difference in survival rates between patients who experienced local progression and those with stable local disease?Methods: Between January 2013 and December 2019, 177 patients at our institution were treated with an intramedullary nail for an impending or completed pathologic fracture. We excluded patients who did not have a pathologic diagnosis of metastasis before fixation, who were younger than 18 years of age, who presented with a primary soft tissue mass that eroded into bone, and who experienced nonunion from radiation osteitis or an avulsion fracture rather than from metastasis. Overall, 122 patients met the criteria for our study. Three fellowship-trained orthopaedic oncology surgeons involved in the care of these patients treated an impending or pathologic fracture with an intramedullary nail when a long bone lesion either fractured or was deemed to be of at least 35% risk of fracture within 3 months, and in patients with an anticipated duration of overall survival of at least 6 weeks (fractured) or 3 months (impending) to yield palliative benefit during their lifetime. The most common primary malignancy was multiple myeloma (25% [31 of 122]), followed by lung carcinoma (16% [20 of 122]), breast carcinoma (15% [18 of 122]), and renal cell carcinoma (12% [15 of 122]). The most commonly involved bone was the femur (68% [83 of 122]), followed by the humerus (27% [33 of 122]) and the tibia (5% [6 of 122]). A competing risk analysis was used to determine the risk of progression in our patients at 1 month, 3 months, 6 months, and 12 months after surgery. A proportion of patients who ultimately underwent reoperation due to progression was calculated. A univariate analysis was performed to determine whether lesion progression was associated with various factors, including the age and sex of the patient, use of adjuvant therapies (radiation therapy at the site of the lesion, systemic therapy, and antiresorptive therapy), histologic tumor type, location of the lesion, and fracture type (impending or complete). Patient survival was assessed with a Kaplan-Meier curve. A p value < 0.05 was considered significant.Results: The cumulative incidence of local tumor progression (with death as a competing risk) at 1 month, 3 months, 6 months, and 12 months after surgery was 1.9% (95% confidence interval 0.3% to 6.1%), 2.9% (95% CI 0.8% to 7.5%), 3.9% (95% CI 1.3% to 8.9%), and 4.9% (95% CI 1.8% to 10.3%), respectively. Of 122 patients, 6% (7) had disease progression around the intramedullary nail and 0.8% (1) had new lesions at the end of the intramedullary nail. Two percent (3 of 122) of patients ultimately underwent reoperation because of local progression. The only factors associated with progression were a primary tumor of renal cell carcinoma (odds ratio 5.1 [95% CI 0.69 to 29]; p = 0.03) and patient age (difference in mean age 7.7 years [95% CI 1.2 to 14]; p = 0.02). We found no associations between local disease progression and the presence of visceral metastases, other skeletal metastases, radiation therapy, systemic therapy, use of bisphosphonate or receptor activator of nuclear factor kappa-B ligand inhibitor, type of fracture, or the direction of nail insertion. There was no difference in survivorship curves between those with disease progression and those with stable local disease (= 0.36; p = 0.54).Conclusion: Our analysis suggests that for this population of patients with metastatic bone disease who have a fracture or impeding fracture and an anticipated survival of at least 6 weeks (completed fracture) or 3 months (impending fracture), the risk of experiencing local progression of tumor growth and reoperations after intramedullary nail stabilization seems to be low. Lesion progression was not associated with the duration of survival, although this conclusion is limited by the small number of patients in the current study and the competing risks of survival and local progression. Based on our data, patients who present with renal cell carcinoma should be cautioned against undergoing intramedullary nailing because of the risk of postoperative lesion progression.Level Of Evidence: Level III, therapeutic study.

The objective of this study was to analyze changes in serum markers of bone turnover across multiple decades in osteoporotic women compared with nonosteoporotic controls, to determine their utility as potential predictors for osteoporosis. Early prediction of those at risk for osteoporosis can enable early intervention before the irreversible loss of critical bone mass. Serum samples were obtained from 20 women given the diagnosis of osteoporosis after age 46 years and 20 age-matched women with normal bone mineral density from 4 time points in their life (ages 25–31, 32–38, 39–45, and 46–60 years). Serum levels of bone turnover markers (propeptide of type I collagen, parathyroid hormone, bone-specific alkaline phosphatase, osteocalcin, C-terminal telopeptide of type I collagen, sclerostin, osteoprotegerin, osteopontin, and 25-OH vitamin D) were measured using commercially available arrays and kits. We used logistic regression to assess these individual serum markers as potential predictors of osteoporosis, and mixed-effects modeling to assess the change in bone turnover markers between osteoporotic and control groups over time, then performed fivefold cross-validation to assess the classification ability of the models. Markers of bone turnover, bone-specific alkaline phosphatase, C-terminal telopeptide of type I collagen, sclerostin, and osteocalcin were all independent predictors at multiple time points; osteopontin was an independent predictor in the 39- to 45-year age group. Receiver operating characteristic analyses demonstrated moderately strong classification ability at all time points. Sclerostin levels among groups diverged over time and were higher in the control group than the osteoporotic group, with significant differences observed at time points 3 and 4. Serum markers of bone turnover may be used to estimate the likelihood of osteoporosis development in individuals over time. Although prospective validation is necessary before recommending widespread clinical use, this information may be used to identify patients at risk for developing low bone mineral density long before traditional screening would ostensibly take place.

Background: Modern techniques in lower extremity amputation have made significant advances to improve prosthetic control and soft-tissue envelopes through various techniques, including medial thighplasties. These advances are necessary to enhance the fit and functionality of the prosthesis in transfemoral amputations., Methods: We performed a retrospective review of all thighplasties performed at our institution in patients with ipsilateral transfemoral amputation from November 2017 to December 2021. We recorded complication rates, types of complications, and treatments throughout this period, and compared it to thighplasty for cosmetic surgery patient outcomes. Univariate statistics were performed using the Student t test and χ 2 analysis to identify differences between the complication and no-complication cohorts, as well as for comparison with published, historical, bariatric surgery, and cosmetic thighplasty controls., Results: There were 46 combined thighplasty and osseointegration procedures, and 12 thighplasty procedures alone, and all patients had a minimum 2-year follow-up. The mean follow-up was 3.39 (2.10-4.05) years. In total, 13 (22%) patients developed a complication: 8 (57%) were due to dehiscence, 2 (14%) were due to seroma, 2 (14%) were due to superficial infection, and 1 (7%) was due to deep infection. Overall, our rate of complication was significantly lower than the overall historical complication rate (22% versus 68%, P < 0.0001)., Conclusions: We demonstrate herein that the overall complication rate for thighplasty undertaken to improve thigh contour and bulk in transfemoral amputees is lower than when thighplasty is undertaken for other indications., Competing Interests: The authors have no financial interest to declare in relation to the content of this article.

Background: Fellowship-trained orthopaedic oncologists in the US military provide routine clinical care and also must maintain readiness to provide combat casualty care. However, low oncologic procedure volume may hinder the ability of these surgeons to maintain relevant surgical expertise. Other low-volume specialties within the Military Health System (MHS) have established partnerships with neighboring civilian centers to increase procedure volume, but the need for similar partnerships for orthopaedic oncologists has not been examined. The purpose of this study was to characterize the practice patterns of US military fellowship-trained orthopaedic oncologists., Questions/purposes: We asked the following questions: (1) What are the diagnoses treated by US military fellowship-trained orthopaedic oncologists? (2) What are the procedures performed by US military fellowship-trained orthopaedic oncologists?, Methods: We queried the Military Data Repository, a centralized repository for healthcare data for all healthcare beneficiaries (active duty, dependents, and retirees) within the Defense Health Agency using the MHS's Management and Reporting Tool for all international common procedure taxonomy (CPT) codes and ICD-9 and ICD-10 codes associated with National Provider Identifier (NPI) numbers of active duty, military fellowship-trained orthopaedic oncologists. Fellowship-trained orthopaedic oncologists were identified by military specialty leaders. Then, we identified all procedures performed by the orthopaedic oncologist based on NPI numbers for fiscal years 2013 to 2022. We stratified the CPT codes by top orthopaedic procedure categories (such as amputation [performed for oncologic and nononcologic reasons], fracture, arthroplasty, oncologic) based on associated ICD codes. These were then tabulated by the most common diagnoses treated., Results: Thirteen percent (796 of 5996) of the diagnoses were oncologic, of which 45% (357 of 796) were malignant. Forty-four percent (158 of 357) of the malignancies were primary and 56% (199 of 357) were secondary; this translates to an average of 2 patients with primary and 2.5 patients with secondary malignancies treated per surgeon per year. During the study period, nine orthopaedic oncologists performed 5996 orthopaedic procedures, or 74 procedures per surgeon per year. Twenty-one percent (1252 of 5996) of the procedures were oncologic; the remaining procedures included 897 arthroplasties, 502 fracture-related, 275 amputations for a nononcologic indication, 204 infections, 142 arthroscopic, and 2724 other procedures., Conclusion: Although military orthopaedic oncologists possess expert skills that are directly translatable to combat casualty care and operational readiness, within MHS hospitals they treat relatively few patients with oncologic diagnoses, and less than one-half of those involve malignancies., Clinical Relevance: Despite postgraduation procedure volume raining stable over the last decade, it is unknown how many new patient visits for oncologic diagnoses and how many corresponding tumor procedures are necessary to maintain competence or build confidence after musculoskeletal oncology fellowship training. It is important to note that there are no military orthopaedic oncology fellowships, and all active duty orthopaedic oncologists undergo training at civilian institutions. Military-civilian partnerships with high-volume cancer centers may enable military orthopaedic oncologists to work at civilian cancer centers to increase their oncologic volume to ensure sustainment of operationally relevant knowledge, skills, and abilities and improve patient care and outcomes., Competing Interests: All ICMJE Conflict of Interest Forms for authors and Clinical Orthopaedics and Related Research® editors and board members are on file with the publication and can be viewed on request., (Copyright © 2024 by the Association of Bone and Joint Surgeons.)

Introduction: Osseointegration is an innovative procedure to attach an external prosthetic device directly to the skeleton. The technique has been shown to improve physical function and quality of life relative to conventional socket prosthetic devices. While much of the research in osseointegration has focused on functional outcomes, less is known regarding perioperative pain management. The purpose of this study was to describe perioperative and postoperative pain management approaches received by patients undergoing osseointegration procedures at a tertiary medical center., Materials and Methods: This retrospective study was determined to be exempt from Institutional Review Board review by the Walter Reed National Military Medical Center Department of Research Programs. Perioperative and postoperative pain management approaches received by 41 patients who underwent 76 staged osseointegration procedures from 2016 to 2021 at Walter Reed National Military Medical Center were described., Results: Pain management approaches included perioperative ketamine (51% stage I, 55% stage II), epidurals (76% stage I, 77% stage II) with a median of 3-4 days across stages, peripheral nerve catheters (27% stage I, 16% stage II), and/or single-shot peripheral nerve block (<10% across stages). The median morphine equivalent dose provided during surgery was 65 mg across both stages, with 56% and 54% of patients also requiring opioid medication in the post-anesthesia care unit. In 11 of 76 (15%) procedures, patients required an increase in the rate or concentration of epidural or peripheral nerve catheter infusion. In six (8%) unique recovery periods, patients experienced a dislodged catheter. In 27 of 76 (36%) unique recovery periods, patients experienced a significant increase in postoperative pain requiring acute pain service intervention in the form of catheter adjustment, intravenous pain medications, and/or the addition of intravenous patient-controlled analgesia. Adequate pain control was achieved with minimal epidural or peripheral nerve catheter trouble-shooting and a bolus for 24 patients (89% requiring intervention). Summed 24-hour pain scores (SPI24) did not vary across stages. SPI24 was positively correlated with opioid doses received. Patients with single, relative to multiple, limb amputations had similar SPI24 values (P > .05)., Conclusions: Variability in pain management requirements calls forth opportunities to optimize osseointegration analgesia care and future research. As osseointegration becomes more accessible, the need for optimizing pain management through patient-centered research becomes more salient., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2024.

Introduction: Complex, high-energy extremity trauma secondary to explosive mechanisms has been increasingly common in modern warfare, accounting for a majority of combat wounds throughout the conflicts in Iraq and Afghanistan. Fellowship-trained orthopaedic trauma surgeons treated many of these complex injuries; however, as the number of casualties continue to decrease during a period of relative peace, a growing concern over maintaining military trauma readiness exists., Methods: The Military Health System Data Repository was queried for all Common Procedural Terminology (CPT) codes associated with 18 fellowship-trained orthopaedic trauma surgeons from 2013 to 2019. The codes were further analyzed and categorized based on common trauma subspecialty procedures such as fracture fixation of the pelvic ring, acetabulum, upper and lower extremity, peri-articular, and nonunion/malunion surgery. We used descriptive statistics to quantify both the average number of cases per surgeon per year in each of the subcategories and case volume among Military Treatment Facilities (MTFs) during the study period., Results: We identified 7,769 CPT codes for surgical procedures throughout the study period. The most common surgical procedures performed were: removal of implant (n = 836, 11%), knee arthroscopy (n = 507, 7%), and debridement of devitalized tissue (n = 345, 4%). The total trauma subspecialty procedural codes and average cases per surgeon per year were as follows: pelvic ring (n = 54, <1 case/year), acetabulum (n = 90, 1 case/year), upper extremity (n = 1,314, 15 cases/year), lower extremity (n = 2,286, 25 cases/year), peri-articular (n = 675, 8 cases/year), and nonunion/malunion (n = 288, 3 cases/year). San Antonio Military Medical Center (SAMMC) accounted for the most fracture-related CPT codes overall (35%), while all other MTFs contributed approximately 10% or less of all fracture-related codes., Conclusions: These results highlight the lack of orthopaedic trauma volume at other MTFs outside of SAMMC, raising concern for maintaining military readiness during an inter-war period of relative peace. The DoD continues to make concerted efforts to maintain readiness through civilian partnerships and subsequently increase surgical case volume for military trauma surgeons. Future efforts should include an in-depth analysis of caseloads of military trauma surgeons providing care at both MTFs and civilian institutions to optimize preparedness in future conflicts., (© The Association of Military Surgeons of the United States 2024.

Background: For patients with transfemoral amputations and difficulty tolerating conventional socket-based prostheses, osseointegrated (OI) implants have enabled increased prosthetic use, improved patient satisfaction, and shown promising functional outcomes 1,2 . Although the use of OI implants effectively eliminates the soft-tissue-related challenges that have plagued socket-based prostheses, the presence of a permanent, percutaneous implant imparts a host of new soft-tissue challenges that have yet to be fully defined. In patients undergoing OI surgery who have redundant soft tissue, we perform a thighplasty to globally reduce excess skin and fat, tighten the soft-tissue envelope, and improve the contour of the residual limb., Description: First, the orthopaedic surgical team prepares the residual femur for implantation of the OI device. After the implant is inserted, the residual hamstrings and quadriceps musculature are closed over the end of the femur, and the subcutaneous tissue and skin are closed in a layered fashion. Although the anatomic location and amount of excess soft tissue are patient-dependent, we perform a standard pinch test to determine the amount of soft tissue that can be safely removed for the thighplasty. Once the proposed area of resection is marked, we proceed with longitudinal, sharp dissection down to the level of the muscular fascia. At this point, we use another pinch test to confirm the amount of soft-tissue resection that will allow for adequate resection without undue tension 3 . Excess subcutaneous fat and skin are carefully removed along the previously marked incisions, typically overlying the medial compartment of the thigh in the setting of patients with transfemoral amputations. The thighplasty incision is closed in a layered fashion over 1 or 2 Jackson-Pratt drains, depending on the amount of resection., Alternatives: Depending on the amount of redundant soft tissue, thighplasty may not be necessary at the time of OI surgery; however, in our experience, excess soft tissue surrounding the transcutaneous aperture can predispose the patient to increased shear forces at the aperture, increased drainage, and increased risk of infection 4 ., Rationale: Although superficial infectious complications are most common following OI surgery, the need for soft-tissue refashioning and excision is one of the most common reasons for reoperation 1,5 . Our group has been more aggressive than most in our use of a vertical thighplasty procedure to globally reduce soft-tissue motion in the residual limb to avoid reoperation., Expected Outcomes: Although much of the OI literature has focused on infectious complications, recent studies have demonstrated reoperation rates of 18% to 36% for redundant soft tissue following OI surgery 1,5 . We believe that thighplasty at the time of OI not only reduces the likelihood of reoperation but may also decrease infectious complications by reducing relative motion and inflammation at the skin-implant interface 4,6 ., Important Tips: The thighplasty procedure is ideally performed as part of the first stage of the OPRA (Osseointegrated Prosthesis for the Rehabilitation of Amputees) procedure to limit the likelihood of problematic ischemia-related complications.We utilize a confirmatory pinch test both before and throughout the thighplasty procedure to ensure adequate resection without undue tension.The thighplasty excision pattern utilizes a long vertical limb designed to decrease the circumferential laxity of the residual limb. Maximal tension is borne on the vertical limb and not on the transverse extensions, as these are prone to scar widening and distortion of surrounding tissues.Closed-suction drainage is utilized liberally to decrease the likelihood of a symptomatic seroma., Acronyms and Abbreviations: OI = osseointegratedOPRA = Osseointegrated Prosthesis for the Rehabilitation of AmputeesPVNS = pigmented villonodular synovitisT-GCT = tenosynovial giant-cell tumor.BMI = body mass indexPMH = past medical history., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSEST/A437)., (Written work prepared by employees of the Federal Government as part of their official duties is, under the United States Copyright Act, a ‘work of the United States Government’ for which copyright protection under that Act is not available.
