The treatment of massive rotator cuff tears (MRCT) is challenging. Insufficient tissue quality, size, and retraction of the cuff often lead to failures of repair. Different techniques like direct repair, partial repair, and graft applications have been developed, but results are not yet predictable. In this arthroscopic technique the objective is not to reconstruct the rotator cuff as a tissue layer but to restore the biomechanical function of the rotator cable with an autograft of the long head of the biceps tendon...

The long head of the biceps brachii is a well-known "pain generator" in the shoulder. Biceps tendinitis, instability, and rupture encompass the majority of symptomatic lesions. Clinical diagnosis, particularly of biceps tendinitis, can be difficult, given the nonspecific physical examination findings. Treatment options are initially nonoperative, with surgical management reserved for specific presentations or refractory cases. In recent years, biceps tenodesis and tenotomy have become the mainstays of operative treatment...

Background: Several procedures have been proposed to address irreparable rotator cuff (RC) tears with pseudoparalysis. One recently proposed procedure is superior capsular reconstruction (SCR) using a tensor fasciae latae (TFL) autograft. Hypothesis: SCR with a locally available long head of the biceps tendon (LHB) autograft is biomechanically equivalent to SCR using TFL autograft for preventing superior humeral migration and the development of RC arthropathy in patients with irreparable RC tears...

BACKGROUND: The purpose of the study was to evaluate the relationship of implant-related injuries to the adjacent anatomical structures in a newer generation straight proximal humeral nail (PHN) regarding different entry points. The proximity of the proximal lateral locking-screws of the MultiLoc proximal humeral nail (ML PHN) may cause iatrogenic tendon injuries to the lateral edge of the bicipital humeral groove (BG) as reference point for the tendon of the long head of biceps brachii (LBT) as well as the lateral insertion of the infraspinatus tendon (IST)...

Background: A devasting course of Iliopsoas Muscle (IPM) abscess remains a challenging therapeutic problem. Methods: A 69-year-old polymorbid male had a history of multiple carcinomas and presented with advanced stage of septic shock due to a right IPM abscess which communicated with the right hip joint and subsequently led to septic hip arthritis accompanied with post-infectious right gluteal deep soft tissue necroses. Management of surgical treatment included abscess revision, coverage with the use of Long Head Biceps Femoris Muscle (LHBFM) 180° turnover flap, and creating a Girdlestone resection-arthroplasty...

BACKGROUND: Although various surgical techniques have been used to treat irreparable rotator cuff tears (RCTs), debate remains regarding which treatment is most effective. The purpose of our study was to compare the outcomes of partial rotator cuff repair versus repair with augmentation of the tenotomized long head of the biceps tendon (LHBT). METHODS: This study included 76 patients with large to massive RCTs. Arthroscopic rotator cuff repair with LHBT augmentation was performed in 39 patients (group I), while partial repair was performed in 37 patients (group II)...

Congenital absence of the long head of the biceps (LHB) tendon is a rare variation in shoulder anatomy. The authors present a case of congenital absence of the long head of the biceps tendon associated with a large insertion of the subscapularis muscle. The patient initially presented with shoulder pain on overhead activity. Shoulder examination was negative for signs of a torn biceps tendon. MRI revealed congenital absence of the LHB tendon, a rim rent tear of the supraspinatus, and a large insertion of the subscapularis muscle...

PURPOSE: The aim of this study is to evaluate the biomechanical parameters of biceps fatigue (time to claudication during elbow flexion) and strength between the shoulder where the tenotomy has been performed and the healthy arm. The hypothesis of this study was that measuring biceps fatigue may be more useful for determining functionality after tenotomy. METHODS: 52 patients from 2 hospitals were selected to undergo biomechanical tests of healthy and pathological arms, before and 12 months after surgery...

Individuals with cerebral palsy (CP) experience impairments in the control of head and neck movements, suggesting dysfunction in brainstem circuitry. To examine if brainstem circuitry is altered in CP we compared reflexes evoked in the sternocleidomastoid (SCM) muscle by trigeminal nerve stimulation in adults with CP and age/sex-matched controls. Increasing the intensity of trigeminal nerve stimulation produced progressive increases in the long-latency suppression of ongoing SCM EMG in controls. In contrast, participants with CP showed progressively increased facilitation around the same reflex window, suggesting heightened excitability of brainstem pathways...
