Recurrent posterior instability of the shoulder can be difficult to diagnose and technically challenging treat. Although not as common anterior instability, recurrent is prevalent among certain demographic sporting groups, may overlooked if one aware typical examination radiographic findings. The diagnosis itself patients typically present with vague or confusing symptoms, treatment has evolved from open arthroscopic surgical techniques. This article intended review anatomy biomechanics...

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....

Acute anterior cruciate ligament (ACL) injuries can be disabling because of prolonged rehabilitation process following surgical reconstructions. Rates ACL among military service members are close to 10 times greater than the general civilian population, likely operation tempo and unique physical requirements. Studies debated functional testing requirements for return sports, but no study investigated impact training re-injury rates reconstruction their association with outcomes time full...

Inferior or subacromial dislocation of the distal clavicle is a rare entity. Previous reports this injury pattern have largely been limited to Rockwood VI acromioclavicular joint (AC) dislocations, with located in subcoracoid position. Few case described inferior being space, and these all previously associated fractures. To our knowledge, no previous report exists literature AC scapular spine fracture. Here, we on 30-year-old right-hand dominant African American male who suffered...

Background: This is a rare case of the surgical treatment subacute presentation latissimus dorsi tendon rupture via posterior single-incision approach. Indications: The patient had extensive conservative, nonoperative that failed, and ultimately intervention was required to return his activities daily living. Technique Description: positioned in lateral decubitus position. A 10-cm incision created along axillary fold. Sharp blunt dissection utilized carefully mobilize chronic rupture....

Abstract Objectives Degenerative rotator cuff tears (DCTs) are the leading cause of shoulder pain, affecting 30%-50% individuals over 50. Current phenotyping strategies for DCT use heterogeneous combinations procedural and diagnostic codes concerning misclassification. The objective this study was to create standardized phenotypic algorithms classify status across electronic health record (EHR) systems. Materials Methods Using a de-identified EHR system, containing chart level data ∼3.5...

Pectoralis minor (PM) tightness has been linked to pain and dysfunction of the shoulder joint secondary anterior tilt internal rotation scapula, thus causing impingement subacromial space.To describe outcomes pertaining nonoperative operative treatment via surgical release PM tendon for pathologic in an active population.Case series; Level evidence, 4.Over a 3-year period, total 46 patients were enrolled (mean age, 25.5 years; range, 18-33 years). Inclusion criteria consisted symptomatic...

Abstract Background Anterior instability has consistently been shown to be the most common type of glenohumeral instability. Recent studies have demonstrated a higher percentage posterior and combined (anterior posterior) than had previously reported; however, this work not replicated recently in particularly young military population, which may representative an especially athletic or high-demand group. Question/purpose What proportion arthroscopic shoulder stabilization procedures are...

Background: Posterior glenohumeral instability is an increasingly recognized cause of shoulder instability, but little known about the incidence or effect posterior glenoid bone loss. Purpose: To determine incidence, characteristics, and failure rate deficiency in shoulders undergoing isolated arthroscopic stabilization. Study Design: Cohort study; Level evidence, 3. Methods: All patients labral repair glenoid-based capsulorrhaphy with suture anchors between 2008 2016 at a single institution...

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...

Recognition and proper treatment of glenoid bone loss (GBL) are important for successful management anterior shoulder instability. Although GBL has been described as the amount bony from front glenoid, there is also a fragment that usually displaced often undergoes attrition. Thus, due to attritional (ABL) fragment, insufficient left fully reconstruct glenoid.To (1) evaluate ABL in recurrent instability (2) correlate with clinical history, size, radiographic findings.Cross-sectional study;...

Although posterior glenohumeral instability is becoming an increasingly recognized cause of shoulder pain, the role glenoid bone loss on outcomes remains incompletely understood. To prospectively determine amount associated with events and to predisposing factors based preinstability imaging. Cross-sectional study; Level evidence, 3. A total 1428 shoulders were evaluated for ≥4 years. At baseline, a subjective history was ascertained each patient, bilateral noncontrast magnetic resonance...

Shoulder instability is one of the most common pathologies seen by orthopedic sports medicine surgeon. With a uniquely young, high-demand patient population in U.S. Military, incidence shoulder remarkably more than civilian population. As such, military surgeons and specialists have developed unique understanding experience instability. The historical advances been instrumental epidemiology, evaluation, pathology, treatment first-time subluxations dislocations, operative non-operative...

Humeral avulsion of the glenohumeral ligament (HAGL) is an infrequent but significant contributor to shoulder dysfunction, instability, and functional loss.To prospectively identify patients with HAGL lesions then conduct retrospective evaluation clinical history, examination findings, surgical outcomes these patients.Case series; Level evidence, 4.Over a 6-year period (2006-2011), dysfunction lesion that was confirmed via magnetic resonance arthrogram (MRA) were evaluated minimum 2-year...

To determine the outcomes scores of military patients who initially present with a variety shoulder conditions, identify which demonstrate highest correlation per diagnosis, and if difference exists for went onto surgery.Two-hundred seventy five consecutive mean age 36.5 +/- 12.9 at presentation completed baseline assessments that included Single Assessment Numeric Evaluation (SANE), American Shoulder Elbow Surgeons (ASES) Score, Western Ontario Instability Index (WOSI), Rotator Cuff (WORC),...

The treatment of ankle fractures often depends on the integrity deltoid ligament. Diagnosis a ligament tear measurement medial clear space. We sought to evaluate impact plantar flexion space.Mortise radiographs were made for twenty-five healthy volunteers, with in four positions (0 degrees, 15 30 and 45 degrees). Four observers measured space superior each radiograph. mean at 0 degrees was defined as control, deviation from control value calculated flexion. ratio determined all radiographs,...
