Is Self-reported Return to Duty an Adequate Indicator of Return to Sport and/or Return to Function in Military Patients?

BACKGROUND: In the military, return-to-duty status has commonly been used as a functional outcome measure after orthopaedic surgery. This is sometimes regarded similarly to return to sports or as an indicator of return to full function. However, there is variability in how return-to-duty data are reported in clinical research studies, and it is unclear whether return-to-duty status alone can be used as a surrogate for return to sport or whether it is a useful marker for return to full function. QUESTIONS/PURPOSES: (1) What proportion of military patients who reported return to duty also returned to athletic participation as defined by self-reported level of physical activity? (2) What proportion of military patients who reported return to duty reported other indicators of decreased function (such as nondeployability, change in work type or level, or medical evaluation board)? METHODS: Preoperative and postoperative self-reported physical profile status (mandated physical limitation), physical activity status, work status, deployment status, military occupation specialty changes, and medical evaluation board status were retrospectively reviewed for all active-duty soldiers who underwent orthopaedic surgery at Madigan Army Medical Center, Joint Base Lewis-McChord from February 2017 to October 2018. Survey data were collected on patients preoperatively and 6, 12, and 24 months postoperatively in all subspecialty and general orthopaedic clinics. Patients were considered potentially eligible if they were on active-duty status at the time of their surgery and consented to the survey (1319 patients). A total of 89% (1175) were excluded since they did not have survey data at the 1 year mark. Of the remaining 144 patients, 9% (13) were excluded due to the same patient having undergone multiple procedures, and 2% (3) were excluded for incomplete data. This left 10% (128) of the original group available for analysis. Ninety-eight patients reported not having a physical profile at their latest postoperative visit; however, 14 of these patients also stated they were retired from the military, leaving 84 patients in the return-to-duty group. Self-reported "full-time duty with no restrictions" was originally used as the indicator for return to duty; however, the authors felt this to be too vague and instead used soldiers' self-reported profile status as a more specific indicator of return to duty. Mean length of follow-up was 13 ± 3 months. Eighty-three percent (70 of 84) of patients were men. Mean age at the preoperative visit was 35 ± 8 years. The most common surgery types were sports shoulder (n = 22) and sports knee (n = 14). The subgroups were too small to analyze by orthopaedic procedure. Based on active-duty status and requirements of the military profession, all patients were considered physically active before their injury or surgery. Return to sport was determined by asking patients how their level of physical activity compared with their level before their injury (higher, same, or lower). We identified the number of other indicators that may suggest decreased function by investigating change in work type/level, self-reported nondeployability, or medical evaluation board. This was performed with a simple survey. RESULTS: Of the 84 patients reporting return to duty at the final follow-up, 67% (56) reported an overall lower level of physical activity. Twenty-seven percent (23) reported not returning to the same work level, 32% (27) reported being nondeployable, 23% (19) reported undergoing a medical evaluation board (evaluation for medical separation from the military), and 11% (9) reported a change in military occupation specialty (change of job description). CONCLUSION: Return to duty is commonly reported in military orthopaedics to describe postoperative functional outcome. Although self-reported return to duty may have value for military study populations, based on the findings of this investigation, surgeons should not consider return to duty a marker of return to sport or return to full function. However, further investigation is required to see to what degree this general conclusion applies to the various orthopaedic subspecialties and to ascertain how self-reported return to duty compares with specific outcome measures used for particular procedures and subspecialties. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Resilience and Patient-Reported Outcomes in Patients Undergoing Orthopedic Hand Surgery.

BACKGROUND: Previous studies have examined the impact of resiliency on postoperative outcomes in other orthopedic domains, but none to date have done so for hand surgery. METHODS: We performed a retrospective analysis of prospectively collected data of patients undergoing hand surgery at a single institution. We included patients with complete preoperative outcomes scores and 6-month follow-up. All patients completed the Brief Resilience Scale (BRS), Disabilities of the Arm, Shoulder, and Hand (DASH) Score, Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Veterans RAND 12-Item Health Survey (VR-12), and Numeric Rating Scale (NRS) for pain. Patients were stratified into high-resiliency (HR) and low-resiliency (LR) groups based on the preoperative BRS score, and outcomes between groups were compared. RESULTS: We identified 91 patients who underwent hand procedures and completed full preoperative and postoperative outcomes measures. There were no observed preoperative differences between the groups in all outcomes scores except the VR-12 Mental Component Score. Postoperatively, the HR group had superior DASH, QuickDASH, and VR-12 (mental and physical component) scores than the LR group. Postoperative pain, as measured by the NRS, was significantly lower in the HR group despite there being no preoperative difference. A larger percentage of patients in the HR group met the minimal clinically important difference in all outcomes except for the VR-12 Mental Component Scores. CONCLUSIONS: Patients with high preoperative resilience appear to have significantly better clinical outcomes following hand surgery with superior DASH, QuickDASH, and VR-12 scores at 6-month follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic study/Level IV evidence.

Relation of Vitamin D Level, BMI, and Location of Lower Extremity Stress Fractures in Military Trainees.

INTRODUCTION: Military trainees are at an increased risk of stress fractures. Vitamin D availability is known to play an important role in both fracture prevention and healing. The purpose of this investigation was to assess 25-hydroxy vitamin D (25(OH)D) levels in soldiers with confirmed lower extremity stress fractures and assess the predictors of fracture location. MATERIALS AND METHODS: Following Institutional Review Board approval, military trainees at a large training base presenting to the orthopedic clinic with a radiographically verified stress fracture were identified. Demographic data and 25(OH)D levels were collected. A descriptive analysis was performed in regard to patient age, body mass index (BMI), and 25(OH)D level. Interactions between variables were assessed using one-way analysis of variance for four fracture location groups (femoral neck, femoral shaft, tibial shaft, and foot and ankle). Bivariate correlations were examined between age, BMI, and vitamin D level. RESULTS: A total of 155 lower extremity stress fractures were identified in 144 males and 11 females over 30 months. The mean age was 22.7 ± 4.85 years. The majority (60.7%) of fractures were located in the femoral neck. The average 25(OH)D level was 26.8 ± 8.37 ng/mL. Overall, 26% (N = 41) of enrolled patients had normal 25(OH)D levels, 48% (N = 74) had insufficient 25(OH)D levels, and 26% (N = 40) had deficient 25(OH)D levels. Patients with femoral neck fractures and tibial shaft fractures had significantly lower BMI than patients with foot and ankle fractures (23.3 vs. 27.7, P < .001 and 24.2 vs. 27.7, P = .003, respectively). Patients with foot and ankle fractures had significantly lower 25(OH)D levels than patients with femoral shaft fractures (21.1 vs. 30.1, P = .02). There were no significant findings regarding age and fracture location. Age correlated positively (but weakly) with BMI (0.338, P < .001). There was no correlation between age and vitamin D level or BMI and vitamin D level. CONCLUSION: Overall, 74% of patients in military training with lower extremity stress fractures had insufficient or deficient levels of 25(OH)D, highlighting a persistent area of concern in this population. Patients with femoral neck and tibial shaft stress fractures had significantly lower BMI than patients with foot and ankle stress fractures. This suggests that in stress fracture-prone patients, BMI may play a role in predicting fracture location.

Muscle Tendon Transfers Around the Shoulder: Diagnosis, Treatment, Surgical Techniques, and Outcomes.

➤: Muscle tendon transfers (MTTs) are effective surgical procedures for reducing pain and for improving active shoulder range of motion and patient-reported outcomes for a wide range of pathologies, including serratus anterior and trapezius muscle palsy, irreparable subscapularis tears, irreparable posterosuperior rotator cuff tears, irreparable posterior rotator cuff tears in the setting of reverse shoulder arthroplasty, and symptomatic complete deltoid deficiency. ➤: The principles of MTT include ensuring that the transferred muscle is expendable, the muscle tendon unit has similar excursion, the line of pull of the transferred tendon and of the recipient muscle are similar in terms of biomechanical force, and the transferred muscle should replace at least 1 grade of strength of the deficient recipient muscle. ➤: When MTT procedures are considered, patients must have exhausted all nonoperative management, have preserved passive range of motion, and have an understanding of the postoperative expectations and potential complications. ➤: For patients with scapulothoracic abnormal motion (STAM) due to long thoracic nerve palsy, the indirect or direct pectoralis major tendon transfer is an effective procedure for reducing pain and improving active forward elevation. For patients with STAM due to spinal accessory nerve palsy, the Eden-Lange or the triple tendon transfer procedures reduce pain and improve active forward elevation and abduction as well as patient-reported clinical outcomes. ➤: Both pectoralis major and latissimus dorsi transfer procedures for isolated irreparable subscapularis deficiency without anterosuperior humeral head escape result in improvement with respect to pain, patient-reported outcomes, and forward elevation, with the pectoralis major tendon transfer demonstrating durable long-term outcomes. ➤: The latissimus dorsi or lower trapezius tendon transfer procedures for irreparable posterosuperior rotator cuff tears reliably improve patient-reported outcomes, forward elevation, abduction, and external rotation range of motion. Additionally, latissimus dorsi transfer with or without teres major transfer can be used to restore active external rotation, both in the native shoulder and in the setting of reverse shoulder arthroplasty. ➤: The complications of MTTs include infection, hematoma, and failure of tendon transfer healing; therefore, it is recommended that these complex procedures be performed by shoulder surgeons with appropriate training.

Biceps Squeeze Tenotomy: Technique to Improve Efficiency of Arthroscopic Biceps Tenotomy.

Biceps tenotomy is a common procedure performed in arthroscopic shoulder surgery. Numerous studies have demonstrated the effectiveness of both biceps tenotomy and tenodesis to relieve pain and restore function for the diagnoses of bicipital tenosynovitis, SLAP tears, rotator interval pulley lesions, and failed SLAP repairs. It is also frequently performed as a concomitant procedure with arthroscopic rotator cuff repair. We report a technique to improve the efficiency of arthroscopic bicep tenotomy using a biceps squeeze maneuver. This is a simple method of manually squeezing the biceps muscle belly while performing the arthroscopic biceps tenotomy. This shortens and tensions the intra-articular portion of the tendon to facilitate a more safe and efficient procedure.

Uncomplicated Arthroscopic Rotator Cuff Repair in Chronic Ipsilateral Upper Extremity Lymphedema: A Case Report.

CASE: A 69-year-old woman with chronic upper extremity lymphedema secondary to bilateral mastectomy and axillary lymph node dissection for breast cancer 10 years before presented to the clinic with a massive rotator cuff tear. Her shoulder pain and dysfunction persisted despite nonoperative treatment. She underwent left shoulder arthroscopic rotator cuff repair (RCR) and biceps tenotomy. Arm, forearm, and wrist circumference measurements were obtained, preoperatively, immediately postoperatively, and 1-week and 2-weeks postoperatively. No permanent increase in extremity circumference measurements was observed. CONCLUSION: This case suggests that it is possible to perform an arthroscopic RCR in a patient with chronic upper extremity lymphedema without creating further morbidity.
