PURPOSE: A new arthroscopic technique with Cobra Guide (CG) was developed to enable fast, controlled and strong intraosseous biceps tenodesis while avoiding an implant. The purpose of this study was to compare the newly developed suture-only biceps tenodesis technique [arthroscopic suprapectoral intraosseous implant-free biceps tenodesis (ASIIBT) with the new CG] to classical interference screws (IS) and suture anchors (SA) in terms of construct resistance to failure. MATERIALS AND METHODS: Fifty-eight human cadaveric shoulders were randomized into three treatment groups...

Introduction: Rupture of the distal biceps brachii results in significant weakness and limitation of function in those affected. Acute ruptures of the biceps tendon are generally best treated with early repair, ideally within 3weeks of injury. The preferred treatment of chronic ruptures is still uncertain. Case Report: We present a case of a chronic distal biceps tendon rupture repaired with a novel, two-incision, minimally invasive anterior approach utilizing an Achilles tendon allograft and cortical button fixation, in a patient with a high demand occupation as a cabinet maker...

INTRODUCTION: The long head of the biceps (LHB) is often resected in shoulder surgery. However, its contribution to inflammatory processes in the shoulder remains unclear. In the present study, inflamed and noninflamed human LHBs were comparatively characterized for features of inflammation. MATERIALS AND METHODS: Twenty-two resected LHB tendons were classified into inflamed ( n = 11) and noninflamed ( n = 11) samples. For histological examination, samples were stained with hematoxylin eosin, Azan, van Gieson, and Masson Goldner trichrome...

Large or massive rotator cuff tears are vexing clinical problems. Current treatment algorithms, while effective for many patients, are associated with failure of repair, persistent pain, and weakness including the inability to use the hand above shoulder level for some. Superior humeral migration associated with large or massive rotator cuff tears may lead to arthrosis or shoulder weakness. The biceps tendon has been reported for superior capsular reconstruction, but not often for reconstruction of the superior labrum...

BACKGROUND: Although subscapularis tendon lesions seem to differ from those of the supraspinatus tendon, the features they have in common suggest that the subscapularis tendon may also have 2 distinct layers. Our aim was therefore to characterize the histologic structure of the subscapularis tendon from its humeral insertion point to the musculotendinous junction. MATERIAL AND METHODS: A histologic study was performed on 10 autopsy samples. The subscapularis tendon was extracted in one piece from the musculotendinous junction to the humeral insertion point and was prepared using standard (hematoxylin-eosin-saffron) staining...

A 27-year-old active-duty male sailor directly accessed physical therapy for deep left anterior shoulder pain. The patient sustained his injury the previous day, when he threw a left hook into the body of his sparring partner, creating a sudden high-energy external rotation force. Based on the patient's complaint, mechanism of injury, and internal rotation weakness, the examining physical therapist ordered magnetic resonance imaging. The images revealed a large partial tear, with retraction of the subscapularis tendon at the lesser tuberosity, a labral tear, and an intratendon biceps tendon tear with subluxation...

Introduction: Variant anatomy of the intra-articular portion of the long head of the biceps tendon (LHBT) is rare, and its clinical significance is poorly understood. However, these variants are encountered with increasing frequency due to increasing use of shoulder arthroscopy. Case Report: We report a case of a trifurcate intra-articular LHBT, a variation which, to our knowledge, has not been previously described. The patient was an adult male presenting with chronic atraumatic shoulder pain that worsened with overhead activity...

OBJECTIVE: The aim of surgical stabilization of proximal humerus fractures is to restore the anatomical relations between the greater and lesser tubercle, to reconstruct the joint and preserve the vascular supply of the fragments. INDICATIONS: Approximately 80% of proximal humeral fractures can be treated conservatively. Surgical treatment is indicated based on the fracture pattern, patient-related factors and the risk of avascular head necrosis. Two-part fractures with a metaphyseal comminution zone and 3/4-part fractures can benefit from near to anatomic reconstruction depending on the patient's demands and bone quality...

Distal biceps tendon injuries are relatively rare. Standard treatment of complete tears and significant partial tears involves surgical anatomical reinsertion of the tendon at the radial tuberosity. Chronic injuries are usually managed with surgical tendon reconstruction using autografts or allografts. Conservative treatment is mostly limited to the elderly, individuals with a very low level of physical activity, patients with evident contraindications to surgical treat-ment, and cases of mild partial tendon tears...

Injuries of the muscle-tendon complex are one of the most frequent non-contact injuries in sports. Particularly in team sports such as football, the demands of the game result in a large number of risk factors. Ekstrand and colleagues1 observed that each team experiences 50 injuries in every season and the hamstrings are most affected. Of these injuries, 83% affect the biceps femoris (BF) muscle2 . Current studies show that despite injury prevention programs, the rate of hamstring injuries has increased by more than 4% in recent years This article is protected by copyright...

Posterior dislocation of the long head of the biceps tendon uncommonly occurs with traumatic shoulder injury. The diagnosis is almost always associated with anterior shoulder dislocation which often cannot be reduced. We present a case of traumatic posterior dislocation of the long head of the biceps tendon with no reported history of shoulder dislocation, but instead a rare and specific radiographic finding. The imaging features are described, the relevant literature reviewed, and salient features discussed...

PURPOSE: To describe 2 superior labral reconstruction techniques using long head of the biceps (LHB) autograft and to investigate the ability of the 2 reconstruction techniques to restore superior restraint to the glenohumeral joint compared with superior labrum-deficient models. METHODS: In this biomechanical study, 10 cadaveric shoulders were cycled on a servohydraulic machine while the force required to cause superior subluxation was recorded. Each specimen was cycled under 4 conditions: intact labrum, SLAP tear, posterior (9- to 12-o'clock position) labral reconstruction using LHB autograft (superior labral reconstruction 1 [SLR1]), and 180° (9- to 3-o'clock position) labral reconstruction using LHB autograft (superior labral reconstruction 2 [SLR2])...

BACKGROUND: Long head of the biceps tendon (LHBT) tenodesis is predominantly performed for 2 reasons: anterior shoulder pain (ASP) or structural reasons (partial tear, dislocation). METHODS: Between 2006 and 2014, all cases of primary LHBT tenodesis performed at an integrated health care system were retrospectively reviewed. Complications were analyzed by tenodesis location (below or out of the groove [OOG] vs leaving tendon in the groove [ITG]), fixation method (soft tissue vs implant), and indication (preoperative ASP vs structural)...

Objectives: Tenotomy and tenodesis of the long head of biceps tendon are effective pain-relieving treatments. However, there is no consensus on the functional outcome after these surgical procedures. We hypothesized that there would be no difference in ambulation parameters after recovery from the surgery between rats that underwent tenotomy versus tenodesis procedures. Methods: Twenty-four New Zealand rats were used and randomly divided into three groups. Each group received one of the following surgeries: tenotomy, tenodesis, and sham operation...
