Background: Anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions are associated with recurrent shoulder instability and higher rates of failure after capsulolabral repair compared similarly treated Bankart lesions. Although these can portend poor outcomes, there limited data on the conditions postoperative course in a young, active population. Purpose: To evaluate mid- to long-term clinical ALPSA repairs assess features outcomes. Study Design: Cohort study; Level evidence, 3....
Background: Targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) procedures have been shown to improve patient-reported outcomes for the treatment of symptomatic neuromas after amputation; however, specific indications comparative each are unclear. The primary research questions were what complement nerves most frequently requires secondary pain intervention conventional amputation, whether this information can guide focused application TMR RPNI amputation...
Posterior glenohumeral instability is an underappreciated cause of disability that may necessitate surgical intervention to allow functional glenoid restoration. However, posterior bone abnormalities, when sufficiently severe, contribute persistent despite a well-performed capsulolabral repair. Recognition and understanding these lesions critical both decision making execution the plan. Numerous procedures have been described address including recent developments in arthroscopic grafting...
Abstract Background Flap-based limb salvage surgery balances the morbidity and complexity of soft tissue transfer against potential benefit preserving a functional when faced with traumatized extremity composite injury. These injuries are well suited for multidisciplinary management between orthopaedic plastic surgeons. Thus, it makes intuitive sense that collaborative, orthoplastic approach to flap-based can result in improved outcomes decreased risk flap failure other complications,...
Background Amputations sustained owing to combat-related blast injuries are at high risk for deep infection and development of heterotopic ossification, which can necessitate reoperation place immense strain on the patient. Surgeons our institution began use intrawound antibiotic powder time closure in an effort decrease rate these surgical complications after initial revision amputations, supported by compelling clinical evidence animal models injuries. Antibiotic may be useful reducing...
Background: There are little long-term health data, particularly in terms of body composition and development metabolic syndromes, to help surgeons guide the decision between limb salvage amputation patients with limb-threatening trauma. The purpose this study was compare outcomes after high-energy lower-extremity trauma who underwent attempted flap-based or amputation. Methods: We performed a retrospective review servicemembers minimum 10-year follow-up followed by unilateral continued...
Background: Anterior instability (AI) of the LM is potentially debilitating in young patients. The use magnetic resonance imaging (MRI) to diagnose AI limited due lack reliable and accurate MRI findings. ability identify preoperatively would improve diagnosis treatment this pathology. This study presents a novel finding (“phantom sign”) for detection demonstrates its reliability accuracy. Methods: Three independent blinded reviewers performed retrospective review preoperative all patients...
To determine whether there is a patient-reported functional difference between combat-related knee disarticulations (KDs) and transfemoral amputations (TFAs).
Bony Bankart lesions of the anterior glenoid arise from traumatic glenohumeral instability events and can predispose persons to recurrent if not surgically stabilized. Large osseous fragments, when repaired anatomically, have excellent stability functional outcomes; however, techniques achieve this repair are often either tenuous or overcomplicated. In technique guide, we describe a based on established biomechanical principles that achieves reliable, anatomic articular surface. This be...
In the acute postoperative period, fluid collections are common in lower extremity amputations. Whether these increase risk of infection is unknown.The purposes this study were to determine (1) percentage patients who develop posttraumatic amputations and natural course collection; (2) whether at increased for infection; ask (3) there objective clinical or radiologic signs that associated with likelihood when a collection present?We performed review all 300 injured combat operations...
Objectives: To correlate femoral neck Hounsfield units (HUs) measured on a computed tomography (CT) scan to dual-energy x-ray absorptiometry (DEXA) T-scores allowing evaluation of bone mineral density (BMD) over time after lower extremity trauma–related amputation. Design: Retrospective cohort study. Setting: United States military trauma referral center. Patients: Military combat-related amputees with both DEXA and CT scans within 6 months each other. Intervention: None. Main Outcome...
Some of the most common human systemic diseases-both benign and malignant-affect bone regulation, formation, homeostasis (the cellular balance regulated by osteocytes, osteoblasts, osteoclasts). This review discusses our current understanding molecular components mechanisms that are responsible for interactions resulting in dysregulation (dysfunction due to loss dynamic equilibrium homeostasis). Knowledge key pathways biology can improve surgeon understanding, clinical recognition, treatment...
Abstract Background High-energy open forearm fractures are unique injuries frequently complicated by neurovascular and soft tissue injuries. Few studies have evaluated the factors associated with nonunion loss of motion after these injuries, particularly in setting blast Questions/purposes (1) In military service members high-energy fractures, what proportion achieved primary or secondary union? (2) What is pronation-supination arc as stratified presence absence heterotopic ossification (HO)...
Abstract Background Combat-related pelvic ring injuries frequently lead to placement of a temporizing external fixation device for early resuscitation and transport. These are commonly complicated by concomitant polytrauma extensive soft-tissue injuries, which may preclude internal prolonged use fixation. To date, few studies have reported on the outcomes definitive combat-related injuries. Questions/purposes (1) In patients treated with after how often is quality reduction within...
Heterotopic ossification (HO) is a devastating condition in which ectopic bone forms inappropriately soft tissues following traumatic injuries and orthopedic surgeries as result of aberrant mesenchymal progenitor cell (MPC) differentiation. HO leads to chronic pain, decreased range motion, an overall decrease quality life. While several treatments have shown promise animal models, all must be given during early stages formation. Methods for determination whether where endochondral...
