Posterior Labral Tear Extension Concomitant With Shoulder Bankart Injuries Is not Uncommon.

Purpose: To identify the rate and risk factors of posterior labral involvement in operatively managed Bankart lesions and assess the effectiveness of MRI arthrogram for preoperative identification of such injury patterns.

Methods: A consecutive cohort of patients undergoing arthroscopic Bankart repair were retrospectively reviewed. All subjects underwent a prearthroscopy MRI arthrogram.

On-Track Lesions with a Small Distance to Dislocation Are Associated with Failure After Arthroscopic Anterior Shoulder Stabilization.

Background: Off-track lesions are strongly associated with failure after arthroscopic Bankart repair. However, on-track lesions with a small distance-to-dislocation (DTD) value, or "near-track lesions," also may be at risk for failure. The purpose of the present study was to determine the association of DTD with failure after arthroscopic Bankart repair.

Clinical Outcomes of an All-Arthroscopic Biceps Tenodesis Using the Anterolateral Anchor During Concomitant Double-Row Rotator Cuff Repair.

Background: Pathology of the long head of the biceps tendon frequently occurs concomitantly with rotator cuff tears, necessitating a surgical treatment, often in the form of a tenodesis procedure. Many techniques for a tenodesis exist; however, they often require additional implants or a separate incision.

Purpose: To report an average of 2-year outcomes of an all-arthroscopic biceps tenodesis employing the stay sutures from the anterolateral anchor during concomitant double-row rotator cuff repair (RCR).

All-Arthroscopic Biceps Tenodesis Using the Anterolateral Anchor During Concomitant Double-Row Rotator Cuff Repair.

Arthroscopic biceps tenodesis is a commonly performed procedure; however, there is a paucity of literature regarding concomitant biceps tenodesis and double-row rotator cuff repair. In this Technical Note, we describe an all-arthroscopic biceps tenodesis using the stay sutures from the anterolateral anchor in the setting of a double-row rotator cuff repair. The anterolateral anchor is placed adjacent to the bicipital groove to accommodate the tenodesis.

Labral Morphology and Number of Preoperative Dislocations Are Associated With Recurrent Instability After Arthroscopic Bankart Repair.

Purpose: To develop a method to measure capsule and labral volume on preoperative magnetic resonance imaging to predict surgical failure after primary Bankart repair.

Methods: A retrospective case-control study was conducted on patients undergoing primary anterior arthroscopic shoulder stabilization. Surgical failure was defined as a recurrent dislocation event.

Anterior Cruciate Ligament Injury and the Anterolateral Complex of the Knee-Importance in Rotatory Knee Instability?

Purpose Of Review: In the setting of rotatory knee instability following anterior cruciate ligament (ACL) reconstruction, there has been a resurgence of interest in knee's anterolateral complex (ALC). Reconstruction or augmentation of the ALC with procedures such as a lateral extra-articular tenodesis (LET) has been proposed to reduce rotatory knee instability in conjunction with ACL reconstruction. The current review investigates the recent literature surrounding the role of the ALC in preventing rotatory knee instability.

Elbow flexion post ball release is associated with the elbow varus deceleration moments in baseball pitching.

The association between breaking pitches and elbow injury remains nebulous. Biomechanical studies have shown that throwing a fastball rather than a curveball results in greater elbow moments, despite some epidemiological studies and pitcher self-report indicating the opposite. This leads to the following question: Are biomechanical studies missing something that could explain this discrepancy? This study evaluated the association between elbow kinematics of baseball pitchers during the deceleration phase of the pitch and the elbow varus moment.

Utilization and Impact of Social Media in Hand Surgeon Practices.

Social media is an effective tool to enhance reputation and brand recognition and is being used by more than 40% of patients when selecting a physician. This study aimed to evaluate the use of social media in hand surgeon practices, and to assess the impact that one's social media presence has on physician-rating website scores (PRWs). Randomly selected hand surgeons from across the United States were identified.

Varus posteromedial rotatory instability: a biomechanical analysis of posterior bundle of the medial ulnar collateral ligament reconstruction.

Background: Recently, there has been growing interest in the involvement of the posterior bundle of the medial ulnar collateral ligament (pMUCL) in varus posteromedial rotatory instability (PMRI). Varus PMRI has been observed clinically, but the degree of involvement of the pMUCL remains unclear. This study assessed the degree to which the pMUCL is involved in stabilizing the elbow and the feasibility of a pMUCL reconstruction to restore stability.

The Posterior Bundle's Effect on Posteromedial Elbow Instability After a Transverse Coronoid Fracture: A Biomechanical Study.

Purpose: There has been increased interest in the role of the posterior bundle of the medial collateral ligament (pMUCL) in the elbow, particularly its effects on posteromedial rotatory stability. The ligament's effect in the context of an unfixable coronoid fracture has not been the focus of any study. The purposes of this biomechanical study were to evaluate the stabilizing effect of the pMUCL with a transverse coronoid fracture and to assess the effect of graft reconstruction of the ligament.

Obesity Is Not a Predictor of Complications in Upper Extremity Surgery.

Background: Obesity is an often-cited cause of surgical morbidity. As a result, many institutions have required screening prior to "clearing" obese individuals for surgery. However, it remains unclear whether such testing is warranted for obese patients prior to upper extremity procedures.

The pyramidalis-anterior pubic ligament-adductor longus complex (PLAC) and its role with adductor injuries: a new anatomical concept.

Purpose: Adductor longus injuries are complex. The conflict between views in the recent literature and various nineteenth-century anatomy books regarding symphyseal and perisymphyseal anatomy can lead to difficulties in MRI interpretation and treatment decisions. The aim of the study is to systematically investigate the pyramidalis muscle and its anatomical connections with adductor longus and rectus abdominis, to elucidate injury patterns occurring with adductor avulsions.

Isolated ligamentous injury can cause posteromedial elbow instability: a cadaveric study.

Background: Elbow posteromedial rotatory instability (PMRI) is known to occur with fracture of the anteromedial coronoid and injury to the posterior bundle of the medial ulnar collateral ligament (pMUCL). However, whether instability results from isolated pMUCL injury remains unclear. The purpose of this study was to quantify displacement about the ulnohumeral joint to evaluate whether isolated sectioning of the pMUCL results in elbow PMRI.

The Epidemiology of Finger Dislocations Presenting for Emergency Care Within the United States.

Background: There are little demographic data on finger dislocation injuries. This study examines the epidemiological characteristics of patients presenting for emergency care of finger dislocations within the United States.

Methods: The National Electronic Injury Surveillance System was queried for finger dislocation injuries treated in US emergency departments between 2004 and 2008.

Importance of the posterior bundle of the medial ulnar collateral ligament.

Background: There has been a renewed interest in the pathomechanics of elbow dislocation, with recent literature having suggested that the medial ulnar collateral ligament is more often disrupted in dislocations than the lateral ligamentous complex. The purpose of this serial sectioning study was to determine the influence of the posterior bundle of the medial ulnar collateral ligament (pMUCL) as a stabilizer against elbow dislocation.

Methods: An elbow dislocation was simulated in 5 cadaveric elbows by mechanically applying an external rotation moment and valgus force.
