Snapping biceps femoris tendon is an uncommon cause of lateral knee pain. We report the case of a 15-year-old athlete with bilateral snapping biceps femoris tendons, painful over his right lateral leg during exercise. He underwent elective exploration of the right knee which revealed an accessory biceps femoris tendon with attachment to the anterolateral tibia. The accessory tendon was released and reinserted onto the fibular head with a Krackow suture. There were no perioperative complications, and he returned to full sporting activities within 3 months...

BACKGROUND: Fractures of the proximal humerus are often associated with lesions of the long head of the biceps (LHB) tendon. This often leads to prolonged shoulder pain. Hence, many surgeons decide to perform a tenodesis of the LHB tendon simultaneous to ORIF. The purpose of this study was to evaluate the postoperative outcome after interlocking plate fixation and biceps tenodesis for treating proximal humerus fractures. METHODS: 56 patients (38 females, 18 male) suffering from proximal humerus fractures who underwent surgery were retrospectively included...

Arthroscopic rotator cuff (RC) repair is now considered as an effective treatment for patients with symptomatic rotator cuff tears. We reported a new method for repairing a full-thickness RC tear by using the double-row technique with transposition of the long head of biceps (LHB). The novelty of this technique is using the long head of the biceps as an augmentation. The indication of this technique consists of two aspects including LHB lesions and RC tears. Three patients were enrolled. An ideal reconstruction of the anatomic footprint of the tendon and stabilization of glenohumeral joint was achieved after the double-row technique with the transposition of the long head of biceps...

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...

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...

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...

The long head of the biceps is a frequent pain generator in the shoulder. Tendinopathy of the long head of the biceps may be treated with biceps tenodesis. There has been great debate about the optimal technique for biceps tenodesis, without a clear distinction between different techniques. Biceps tenodesis fixation may include interference fixation, suspensory fixation, all-suture anchors, and soft tissue fixation. In this technical note, we describe an all-arthroscopic onlay suprapectoral biceps tenodesis with an all-suture anchor...

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...

The sacrotuberous ligament (STL) has been linked to conditions such as pelvic girdle pain and pudendal nerve entrapment, yet its contribution to pelvic stability is debated. The purpose of this review was to explore the current understanding of the STL and highlight any gaps in knowledge regarding its anatomy and function. A systematic search of the literature was conducted, focussing on the morphology and attachments of the STL, the relationship of the STL with surrounding structures, and its neurovascular supply and function...

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...

The purpose of this study was to investigate differences in the acute effects of passive knee extension (PKE) and active knee extension (AKE) stretching on the shear elastic modulus of the hamstrings. In 20 healthy men, maximum knee extension (maximum range of motion [ROM]) and shear elastic modulus of the hamstrings (biceps femoris long head, semitendinosus, semimembranosus) were measured before (Pre) and after (Post) AKE and PKE stretching. The maximum ROM during stretching was measured. In both stretching methods, maximum ROM increased and the shear elastic modulus decreased (p<0...

A snapping biceps tendon is an infrequently seen and commonly misdiagnosed pathology, leaving patients with persistent symptoms that can be debilitating. Patients will present with a visible, audible, and/or painful snap over the lateral aspect of their knee when performing squats, sitting in low seats, or participating in activities with deep knee flexion. A thorough knowledge of the anatomy is essential for surgical treatment of this pathology, which is caused by a detachment of the direct arms of the long and short heads of the biceps femoris off the fibular styloid...

BACKGROUND: Pathological movement patterns are characterized by abnormal kinematics, kinetics and muscle activations that alter the distribution of muscle forces during walking. AIM: The objective of this study was to identify what compensatory strategy is evident in muscle force distribution in patients with drop-foot, in response to weakness in the dorsiflexor muscles. METHODS: A sample of 10 patients with drop-foot were evaluated by a computerized gait analysis system and compared to a group of 10 healthy subjects...

Diagnosis is crucial in decision-making when treating a patient with shoulder pain. Ultrasound is also very important in the diagnostic and therapeutic pathway, especially when surgery is being considered. This article outlines the diagnostic pathway using the patient's history, physical examination and ultrasound examination. It is important to correlate the clinical assessment with the imaging signs. It is also important to treat the patient and not the images as there may be abnormalities detected on imaging that are not symptomatic...
