Consensus and Equipose in the Management of Military Trainee Femoral Neck Stress Fractures: A Survey of Military Surgeons.

Femoral neck stress fractures (FNSFs) are a unique injury pattern not commonly treated in the civilian trauma population; however, it is particularly high with military trainees engaged in basic combat training. To date, no study has surveyed a population of military orthopedic surgeons on treatment preferences for military service members (SMs) with FNSF. We aim to evaluate the extent of clinical equipoise that exists in the management of these injuries, hypothesizing that there would be consensus in the factors dictating surgical and non-surgical intervention for FNSF. A 27-question survey was created and sent to U.S. military orthopedic surgeon members of the Society of Military Orthopaedic Surgeons. The survey was designed in order to gather the experience among surgeons in treating FNSF and identifying variables that play a role in the treatment algorithm for these patients. In addition, seven detailed, clinical vignettes were presented to further inquire on surgeon treatment preferences. Binomial distribution analysis was used to evaluate for common trends within the surgeon's treatment preferences. Seventy orthopedic surgeons completed the survey, the majority of whom were on active duty status in the U.S. Military (82.86%) and having under 5 years of experience (61.43%). Majority of surgeons elected for a multiple screw construct (92.86%), however the orientation of the multiple screws was dependent on whether the fracture was open or closed. Management for compression-sided FNSF involving ≥50% of the femoral neck width, tension-sided FNSF, and stress fractures demonstrating fracture line progression had consensus for operative management. Respondents agreed upon prophylactic fixation of the contralateral hip if the following factors were involved: Complete fracture (98.57%), compression-sided fracture line >75% (88.57%), compression-sided fracture line >50-75% with hip effusion (88.57%), contralateral tension-sided fracture (87.14%), and compression-sided fracture line >50-75% (84.29%). An FNSF < 50% on the contralateral femoral neck or a hip effusion was indeterminate in surgeons indicating need for prophylactic fixation. Majority of surgeons (77.1%) utilized restricted toe-touch weight-bearing for postoperative mobility restrictions. Consensus exists for surgical and non-surgical management of FNSF by U.S. military orthopedic surgeons, despite the preponderance of surgeons reporting a low annual volume of FNSF cases treated. However, there are certain aspects in the operative and non-operative management of FNSF that are unanimously adhered to. Specifically, our results demonstrate that there is no clear indication on the management of FNSF when an associated hip effusion is involved. Additionally, the indications for surgically treating contralateral FNSF are unclear. IV.

Relevance of a Simulation Model to Microvascular Surgery for Military Surgical Residents.

Microsurgical training is an asset for deployed military orthopaedic surgeons who frequently treat hand or nerve injuries in the field. The objective of this study was to evaluate a microvascular surgery simulation model intended to prepare residents prior to their enrolment in conventional microsurgery degree training. An experimental study was conducted to evaluate technical progress and satisfaction of military surgical residents using a model based on Japanese noodles with four tests of increasing difficulty. Objective endpoints included instruments handling, distribution, and quality of stitches, as well as anastomoses duration. Responses to the Structured Assessment of Microsurgery Skill self-assessment questionnaire were also analyzed. Nine residents from different specialties participated in the study. Their anastomoses quality and average satisfaction significantly increased between the first and the last session (p < 0.05). Conversely, the average operating time decreased significantly over the sessions (p < 0.001). This simulation model seems to constitute a satisfactory initiation to microsurgery and could limit the use of animal models. It could also be included in the continuing education of military surgeons who have an occasional microsurgical practice during deployments.

Pipeline to Military Orthopaedic Leadership: 20 Years of Race and Gender Diversity Trends Within Military Orthopaedic Surgery Fellowship Training.

The lack of trainees from underrepresented race and gender backgrounds in orthopaedic surgery fellowship training has been well reported in the literature. The purpose of this study was to investigate the demographic trends of federally sponsored military orthopaedic surgery fellows in the Army, Navy, and Air Force. We hypothesize that there has been an increase in women selected for fellowship but that there has been no change in the race demographics of military fellows over the past 2 decades. A retrospective review of all available demographic data collected by the Army, Air Force, and Navy since the beginning of tracking federally funded fellowship training in orthopaedic surgery was completed (1998-2021). Data were grouped into 4-year periods for analysis to closely mirror the military assignment cycle. Three hundred sixty-two military orthopaedic surgery fellowship board selectees were included in our analysis. The proportion of women fellows increased from 3% (n = 2/69) over 2001 to 2004 to 21% (n = 17/82) during 2017 to 2020 (p < 0.05). Fellows who identified as White comprised 82% (n = 297) of the cohort during the study period. Individuals who identified as Asian were the next highest proportion of fellows at 4% (n = 16), followed by Black (n = 14, 4%) and Hispanic (n = 13, 3%). Individuals who identified as Native Hawaiian/Pacific Islander represented 1% (n = 3), and an additional 6% (n = 20) fellows identified as "other" or "undeclared." Over the 20-year study period, representation of Asian, Black, Native Hawaiian, and Hispanic fellows did not increase (p = 0.79, 0.81, 0.45, 0.34, respectively). Within military orthopaedics, there has been increased representation of women in fellowship training over the past 20 years. However, the proportion of fellows from underrepresented racial and ethnic groups has remained stagnant. One barrier to improving gender and race representation is the currently imprecise and inconsistent collection of demographic information. Importantly, fellowship training has a direct effect on future leadership opportunities within the military orthopaedic surgery community. A more diverse leadership may help to inspire future generations of military orthopaedic surgeons. IV.

Racial and Gender Diversity of Physicians Accepted to American Military Orthopaedic and Surgical Residencies: An 18-Year Analysis.

We performed a retrospective cohort study evaluating matriculation into first year of residency training in US military surgical training programs between 2002 and 2020. In total, 9,124 applicants were reviewed. We collected matriculant self-reported race/ethnicity and sex and the medical/specialty program. We considered under-represented minorities as those who reported their race as African American, Indian/Alaskan Native, and Native, other, or who reported ethnicity as Hispanic. We calculated changes in persons accepted to training positions over time and used linear regression to model trends in diversity among orthopaedic matriculating residents when compared with other surgical subspecialities over time. Across all surgical subspecialities, the average change in percent women was 0.94% per year for the study period (p < 0.01). The average annual percent women entering orthopaedic surgery residency programs was 14% for the 18-year study period. Across all surgical subspecialties, the average change for accepted applicants from groups underrepresented in medicine (URiM) was 1.01% per year for the study period (p < 0.01). The average annual percent URiM entering orthopaedic surgery residency programs was 17% for the 18-year study period. The annual change of women and URiM entering military orthopaedic residencies was 0.10% and 1.52%, respectively. Despite statistically significant improvements, recruitment efforts as used to date fall far short of reversing sexual, racial, and ethnic disparities in military orthopaedic residencies. Orthopaedics has a lower representation of both women and physicians with minority backgrounds when compared with many surgical subspecialties. Additional interventions are still necessary to increase diversity for military orthopaedic surgeons.

Prevalence of flatfoot among young Korean males and the correlation among flatfoot angles measured in weight-bearing lateral radiographs.

Flatfoot causes significant fatigue and pain while walking, and even asymptomatic flatfoot may increase the risk of metatarsal stress fracture during long-distance walking. While most studies have used physical examination or plantar footprints to diagnose flatfoot, a weight-bearing radiograph of the foot provides more objective data. However, data on the prevalence of flatfoot in Asian populations gathered in a nationwide cohort of a specific age group is lacking. We examined the prevalence of flatfoot among 19-year-old male Korean army recruits using a weight-bearing lateral radiograph and evaluated the correlation among flatfoot angles. A total of 560,141 19-year-old Korean males were examined at the regional Military Manpower Administration offices between April 2018 and April 2020. Weight-bearing lateral radiographs of the foot were obtained using an X-ray system while the subjects were standing on a table with their feet in a neutral position. Based on these radiographs, military orthopedic surgeons and radiologists measured the talo-first metatarsal angle (TMA) and calcaneal pitch angle (CPA) for flatfoot diagnosis. Mild flatfoot was diagnosed when the TMA ranged from 6 to 15° or the CPA was <17°, and moderate-to-severe flatfoot was diagnosed when the TMA was 15° or greater or the CPA was <10°. Pearson correlation coefficients and scatter plot matrix were used to evaluate the correlation among the flatfoot angles. Finally, we evaluated the relationship between body mass index (BMI) and flatfoot angles and compared the BMI in subjects with or without self-checked foot deformities including flatfoot and pes cavus. Of the 560,141 subjects, 16,102 (2.9%) were diagnosed as flatfoot, and 5265 (0.9%) were diagnosed with moderate-to-severe flatfoot. The coefficients between TMA and CPA ranged from 0.342 to 0.449 (all P values < 0.001), and those between the 2 sides of TMA and CPA were 0.709 and 0.746 (all P values < 0.001), respectively. BMI had a significant correlation with both TMA and CPA in subjects with flatfoot, and those with self-checked foot deformities had a significantly higher BMI than the group without foot deformities. The prevalence of total flatfoot and moderate-to-severe flatfoot in 19-year-old Korean males based on a weight-bearing lateral radiograph was 2.9% and 0.9%, respectively. The correlation coefficients between TMAs and CPAs showed a low degree of positive correlation. Higher BMI was associated with the likelihood of the presence of flatfoot.

Ascertaining the Readiness of Military Orthopedic Surgeons: A Revision to the Knowledge, Skills, and Abilities Methodology.

Decay of military surgeons' critical wartime skills is a persistent and growing concern among leaders in the military health system (MHS). The Knowledge, Skills and Abilities (KSA) Clinical Readiness Program was developed to quantify the readiness of clinicians in the MHS; however, the utility of the data is questionable due to a lack of focus on the operative expeditionary skillset in the original methodology. A revised methodology emphasizing the most relevant to expeditionary orthopedic surgery procedures is described. All Current Procedural Terminology (CPT) codes included in the original KSA methodology were reviewed and, if appropriate, removed, or reassigned to more suitable categories. Category scores were weighted to better align with the most performed procedures in the deployed environment. All surgical cases and procedures performed from 2017-2019 in military treatment facilities by orthopedic surgeons were recorded in total and by MHS market. Cases were recorded for all military orthopedic surgeons who performed at least one KSA credit procedure during the study period. The 10 MHS markets with the greatest number of procedures were included in the analysis. The change in creditable KSA procedure codes and procedures performed from the original to revised methodology was determined for each KSA category and MHS market. Overall, 403 CPT codes were recategorized and 79 were deleted from the original KSA methodology. The deletions represented less than 4% of the original creditable CPT codes, with most being supply or injection codes. Three of the five most common expeditionary KSA categories increased in the number of creditable procedure codes. The impact of the revision on the MHS markets was mixed, but the overall volume of credited procedures decreased. The weighted scoring did not disproportionately affect the analyzed markets. The revised methodology is better aligned with the most common procedures in the most recent large-scale military engagements. The improved applicability of the KSA scoring to necessary CWS will allow military medical leaders to better determine the readiness opportunities available in the MHS.

Billing and Coding Education and Knowledge Among Military Orthopaedic Surgeons

Objectives: The purpose of this study is to evaluate the current level of billing and coding knowledge among resident and staff military orthopaedic surgeons. Design: Prospective survey, training, and assessment. Setting: Academic Military Level 1 Trauma Center. Intervention: Voluntary, anonymous survey relating to practice setting, billing, and coding practices, type of residency training and prior education on the subject. A quiz consisting of 23 questions to assess billing and coding knowledge. Main outcome measurement: Survey results and quiz scores. Results and conclusions: We had 68 responses comprised of 23 residents and 45 staff orthopaedic surgeons. Among residents, 86.14% (20/23) reported that they code encounters yet only 17.39% (4/23) responded that they have had formal training on billing and coding. 91.30% (21/23) felt that this topic should be taught in residency training. Among staff surgeons, 93.33% (42/45) code their own encounters and 42.22% (19/45) reported formal training on billing and coding. 93.33% (42/45) of staff felt that billing and coding should be taught in residency. The average quiz scores among residents and staff were 43.48% and 58.36%, respectively (p&lt;0.0001). Scores among those with prior training in billing and coding were significantly higher overall (p= 0.033). Among staff there was no significant differences in scores related to years of experience, residency type, working with residents, years remaining in the military or participation in off-duty employment. Conclusion: There remains a paucity of formal training on billing and coding among military orthopaedic surgeons and this problem is not unique to military orthopaedic residency training programs. Those with formal training in billing and coding performed significantly better than those without, indicating that formal billing and coding training as part of graduate medical education may be effective in improving billing and coding knowledge among military orthopaedic surgeons. Level of Evidence: IV; survey Keywords: Billing, Coding, Medical education, Practice management.

Military Orthopedic Surgeons Are Not Just Traumatologists.

Each French military orthopedic surgeon is both an orthopedic surgeon and a trauma surgeon. Their mission is to support the armed forces in France and on deployment. The aim of this study was to describe the type of orthopedic surgery performed for the armed forces in France. Our hypothesis was that scheduled surgery was more common than trauma surgery. We conducted a retrospective descriptive analysis of the surgical activity for military patients in the orthopedic surgery departments of the four French military platform hospitals. All surgical procedures performed during 2020 were collected. We divided the procedures into the following categories: heavy and light trauma, posttraumatic reconstruction surgery, sports surgery, degenerative surgery, and specialized surgery. Our primary endpoint was the number of procedures performed per category. A total of 827 individuals underwent surgery, 91 of whom (11%) were medical returnees from deployment. The surgeries performed for the remaining 736 soldiers present in metropolitan France (89%) consisted of 181 (24.6%) trauma procedures (of which 86.7% were light trauma) and 555 (75.4%) scheduled surgery procedures (of which 60.8% were sports surgery). Among the medical returnees, there were 71 traumatology procedures (78%, of which 87.3% were light traumatology) and 20 procedures corresponding to surgery usually carried out on a scheduled basis (22%, of which 95% were sports surgery). Military orthopedic surgeons are not just traumatologists; their activity for the armed forces is varied and mainly consists of so-called programmed interventions.

Retired French Military Orthopedic Surgeons’ Opinions on Their Careers

Owing to their professional and personal experiences, retired military orthopedic surgeons' views of their careers are a unique source of inspiration. Reflecting on their experiences allows them to grasp the positive points and those that need to be improved for future generations. The purpose of this study is to gather the opinions of retired surgeons on the career of military orthopedic surgeons. We addressed a questionnaire to all retired French military orthopedic surgeons in the database of the Chair of Applied Surgery for the Armed Forces as of December 2020, retrained in the civilian sector. A questionnaire sent by email made it possible to collect demographic, professional, and personal data about their careers. Subjective data were evaluated using a visual analog scale from 0 to 10 or a subjective qualification scale. The main assessment criterion was the average score (out of 10) of the retired surgeons' opinions on their careers. Fifty-two percent of retired surgeons replied (32 out of 61), with the respondents having an average age of 63 years. They had been in military retirement for an average of 14 years and had practiced for approximately 13.5 years. The majority (28 out of 32) had had a civilian activity after leaving the army. The three main reasons for leaving were the unsatisfactory working environment, the high number of deployments, and insufficient pay. Nevertheless, the respondents were satisfied with their activity, their job, and their training. The average score given for the overall opinion on their careers was 8.14/10. The three main disadvantages of the career that were noted were the quality of family life, the conditions of employment, and the financial aspects. The majority were very satisfied with the second half of their civil career. Overall, the opinion of retired French military orthopedic surgeons on their careers is very good. Their point of view provides interesting elements for reflection from both a professional point of view and a personal point of view. They were very satisfied with the quality of their training, their job, and their activity. However, the quality of their personal/family life, working conditions, and the financial aspects of the career reduced this satisfaction. The results also have potential application in improving the preparation of young military orthopedic surgeons.

Functional Outcome of Modified Open Bankart Surgery in Military Personnel for Traumatic, Recurrent, Anterior Glenohumeral Dislocations

Introduction: This study evaluates the functional outcome of modified open Bankart surgery in military personnel for traumatic, recurrent, anterior glenohumeral dislocations. With the arthroscope unavailable, there was no selection bias and 5 military orthopedic surgeons used modification of the Bankart procedure. Metallic suture anchors were used for repair of avulsed labrum along with capsular repair.

Current Practice Patterns in Anterior Cruciate Ligament Reconstruction Among Fellowship-Trained Military Orthopaedic Surgeons

PurposeTo evaluate current practice patterns in anterior cruciate ligament reconstruction (ACLR) surgery among fellowship-trained military surgeons.MethodsThe MOTION database is a prospectively collected dataset of intraoperative variables across the Military Health System. This database was queried using Current Procedural Terminology code 29888 for ACLR among active-duty service members between October 2016 and December 2019. The intraoperative data pertaining to ACLR involving both isolated primary ACLRs and primary ACLRs combined with meniscal or chondral injuries were extracted with patient age, sex, and rank.ResultsTwo hundred sixty-six primary ACLRs performed by 21 fellowship-trained orthopaedic surgeons at 9 MTFs were identified. The mean age of patients undergoing ACLR was 27.2 ± 7.7 years. Bone–patellar tendon–bone autograft was the most commonly used graft source (137 of 266 [51.5%] cases.) Meniscal injuries were treated with an isolated debridement in 53 of 156 (34.0%) tears, whereas meniscal repair was performed in 86 of 156 (55.1%) tears. Concomitant chondral pathology was noted in 43 of 266 cases (16.2%) and most commonly addressed with chondroplasty (25 of 49 [51.0%] chondral lesions).ConclusionsBone–patellar tendon–bone autograft was the most commonly used graft type in ACLR among fellowship-trained surgeons treating active-duty service members. Concomitant meniscal pathology was encountered at rates comparable with what has been previously reported, and meniscal repair was favored over meniscal debridement in more than 50% cases.Level of EvidenceLevel IV: Therapeutic case series.

Total Joint Arthroplasty Volume in the Military Health System.

The relationship between volume and outcome of total knee arthroplasties is a concern in both the civilian and military patient populations. We sought to compare surgeons and hospital procedure volumes performed on military service members and define factors leading to increased civilian referrals. The Military Health System Data Repository (MDR) contains patient information on all healthcare beneficiary encounters, including care provided both in Military Health System (MHS) facilities and in civilian network facilities. The Military Analysis and Reporting Tool (M2) queried the MDR for all patients between 2011 and 2015 with a CPT code for hip or knee arthroplasty associated with a provider HIPAA taxonomy code for orthopedic surgery. M2 enrollee encounters were used to calculate the total number of arthroplasty procedures performed by both military and civilian orthopedic surgeons on MHS enrollees as well as the incidence rate of arthroplasty procedures. Logistic regression was used to predict which cases were more likely to have been treated at military treatment facilities using patient gender, sponsor service branch, age, and beneficiary category. During the study period, a total of 12,627 military facility arthroplasty cases and a total of 142,637 civilian facility arthroplasty cases were performed on TRICARE enrolled patients. The total number of military surgeons performing arthroplasty on TRICARE enrolled patients was 323, while the total number of civilian surgeons performing arthroplasty was 10,245 during the same time period; the number of military surgeons performing arthroplasty on active duty patients was 176, and the total number of civilian surgeons performing arthroplasty on military patients was 1045. Overall, including retirees and activity duty service members, more procedures are performed by civilian network surgeons than military surgeons in all states. In an adjusted model, male patients were slightly more likely to receive care at an military treatment facilitie than female patients (OR=1.47, 95% CI: 1.41-1.53). Furthermore, with respect to service, patients with Air Force (OR: 1.08, 95% CI: 1.02-1.15) and Navy sponsors (OR: 1.61, 95% CI: 1.51-1.71) were more likely to receive military care than patients with Army sponsors. Based on our findings, we recommend the MHS focus attention to recapturing the Army active duty male patients who are more likely to receive care outside of the military healthcare network. Further analysis of the many factors including, but not limited to, referral process for total joint arthroplasty, time to procedure, and facility resources is required, in addition to assessing patient outcomes following the procedures.

Has Current French Training for Military Orthopedic Surgeons Deployed in External Operations Been Appropriately Adapted?

The current evolution of surgical practices is increasingly trending toward hyper-specialization. For military surgeons, their practice in France does not differ from their civilian counterparts. In contrast, in external operations, they have to deal with specific war injuries in austere conditions. They are also required to take care of local populations. Therefore, specific training is necessary, and the French Military Health Service Academy (Ecole du Val-de-Grâce) Paris has set up a specific training called Advanced Course for Deployment Surgery (ACDS) in 2007. The aim of this study is to assess the relevance of this teaching regarding pathologies encountered during current conflicts. The activity of deploying orthopedic surgeons during the three recent major external operations (Afghanistan, Mali, and Central African Republic) has been retrospectively recorded in terms of global volume, types of trauma, status of patients who had been operated on, and indications. These data have been compared with teaching during the ACDS. Our study found a high variability in terms of operating volume, types of trauma, patients' statuses, and types of operations performed depending on the operation theaters. The volume of surgical activity carried out within Role 3 is much more important than that in Role 2 with more than half of the surgeries performed as scheduled surgery to the benefit of the local population. Within advanced Role 2 surgical structures deployed in Mali and Central Africa, more than 70% of the activity was performed as emergencies. Surgical indications were varied, ranging from emergency surgery to limb reconstructive surgery. A lot of non-orthopedic procedures such as vascular repairs and decompressive craniotomies were also performed. All of the encountered pathologies were taught during ACDS. The large variety and technical nature of the performed operations requires the training of highly qualified military orthopedic surgeons with both experience in war surgery and management of after-effects and complications. Orthopedists are also required to carry out procedures dealing with neurosurgery, general, and/or vascular surgery on missions. These data highlight the complexity of military surgeons' training along with the hyper-specialization of the civilian medical world. For more than 10 yr, French military surgeons have benefited from a training program called ACDS to meet these objectives. This initial training seems to be appropriated adapted in view of the managed pathologies.

Contemporary Surgical Trends in the Management of Symptomatic Meniscal Tears among United States Military Servicemembers from 2010 to 2015.

The purpose of this investigation is to report on trends over time in the treatment of meniscal pathology among military orthopaedic surgeons, as well as to evaluate the impact of patient demographics and concomitant procedure on the type of meniscal procedure performed. We performed a retrospective analysis of all active-duty United States military servicemembers who underwent a meniscal procedure from 2010 to 2015 within the Military Health System. Patient demographics and surgical variables were extracted from the electronic medical record. Treatments were categorized by location and by type of intervention (i.e., repair or debridement). Chi-square and linear regression analyses were performed to identify temporal trends in meniscal procedures and factors that were correlated with the type of meniscal procedure performed. Out of 29,571 meniscal procedures analyzed, partial meniscectomy was performed in 81.3% (n = 24,343) of cases, meniscal repair in 20.3% (n = 6,073), and meniscus allograft transplantation (MAT) in 0.7% (n = 206). The rates of debridement, repair, and concomitant surgeries did not demonstrate any significant temporal trends, whereas MAT demonstrated a significant decrease in overall utilization. Nearly two-thirds of all meniscal procedures were performed in the medial compartment. MAT occurred equally between the medial and lateral compartments. Lateral meniscal lesions demonstrated significantly higher rates of debridement. With each year of advancing age, there was a 3.7% increasing likelihood of meniscectomy and 6.5% decreasing likelihood of repair. Females were more likely to undergo meniscal repair than males. Patients in the military population were more likely to undergo meniscal repair compared with previously reported rates in the civilian population. In this physically active cohort of nearly 30,000 military patients, 1 in 5 meniscal tears were treated with meniscal repair. Meniscal repairs were performed at a higher rate for all age groups compared with previously reported rates in the civilian population. Further research is required to elucidate the causative factors behind these differences and the effect on postoperative outcomes. LEVEL OF EVIDENCE: : IV, cross-sectional study.

A History of Shoulder Instability in the Military: Where We Have Been and What We Have Learned.

Shoulder instability is one of the most common pathologies seen by the orthopedic sports medicine surgeon. With a uniquely young, high-demand patient population in the U.S. Military, the incidence of shoulder instability is remarkably more common than the civilian population. As such, military orthopedic surgeons and sports medicine and shoulder specialists have developed a unique understanding and experience of shoulder instability. The historical advances of shoulder instability in the military have been instrumental in understanding the epidemiology, evaluation, pathology, treatment of first-time shoulder subluxations and dislocations, operative and non-operative treatment options, arthroscopic and open stabilization methods, management of the in-season athlete, treatment of combined and circumferential labral pathology, and associated pathology. The purpose of this article is to chronicle the experience of military orthopedic surgeons in treating shoulder instability. We discuss how this unique experience has led to a better understanding of the epidemiology and pathology of this condition and how we have adapted our clinical practice to improve patient outcomes. The historical contribution of U.S. Military orthopedics to the understanding of shoulder instability has been monumental. This article reviews the evolution of shoulder instability treatment and the understanding as it has evolved in the U.S. Military. It further elaborates on our understanding of the epidemiology of shoulder instability in the U.S. Military, with attention given to our incidence of 1.69 per 1000 person-years, approximately 20 times higher incidence than the general population. We discuss known risk factors for dislocation that contribute to this incidence, which are specific to military service. We address pathologic changes seen following a first-time instability event, including an analysis of labral injury and the role of these pathologic changes in recurrent instability. We also review our results from arthroscopic evaluation of first-time dislocations and compare the pathologic changes with those following a first-time subluxation. Evaluation of treatment outcomes is discussed, comparing operative and non-operative results as well as open and arthroscopic stabilization in the U.S. Military population and contact/collision athletes. Finally, we address how these results drive our current treatment algorithm. The physical demands of military service result in a high rate of shoulder instability relative to the general population. For years military orthopedic surgeons have sought to better understand this pathology and learn how to optimally manage it so as to reduce this heavy burden of disease. This article discusses our experience with treating shoulder instability, provides an overview of the lessons learned, and provides a historical perspective for the evolution of shoulder instability understanding in the U.S. Military.
