INTRODUCTION The standard anatomical description of the extensor pollicis brevis tendon provided in textbooks of anatomy is at odds with that of published anatomical studies. It is crucial to the hand surgeon that he or she has a clear understanding of its anatomy, including its variations. The aim of this study was to provide a comprehensive review of the current literature on the anatomy and ...

In tetraplegia, hand reconstruction is of high priority. Key pinch has been advocated for tetraplegia because the lack donors nerve and tendon transfers. We report a patient with mid-cervical who underwent transfers in right left upper limbs seven months post-injury to reconstruct function. The particularity our case resides left-hand thumb index pulp-to-pulp reconstruction. For this, we transf...

The morphology of the extensor carpi radialis brevis (ECRB) muscle was investigated in 20 patients with longstanding lateral epicondylitis. Muscle biopsies were obtained from the proximal or distal portion of the ECRB and analysed by enzyme- and immunohistochemical methods. Morphological abnormalities were significantly more frequent in patients than controls and included moth-eaten fibres, fib...

Lateral epicondylitis, also known as tennis elbow, is a common condition that is estimated to affect 1% to 3% of the population. The word epicondylitis suggests inflammation, although histological analysis on the tissue fails to show any inflammatory process. The structure most commonly affected is the origin of the tendon of the extensor carpi radialis brevis and the mechanism of injury is ass...

In 1921 Sir Robert Jones described his technique of tendon transference for cases of irreparable damage of the radial nerve. In the original Jones’s technique and its several modifications (Billington 1922, Luckey and McPherson 1947, Scuderi 1949) the pronator teres is transferred to the two radial wrist extensors. This leads to ugly radial deviation on attempted dorsifiexion of the wrist (Fig....

HYPOTHESIS Lateral epicondylitis usually responds well to nonoperative management. A limited number of refractory cases may require surgical intervention. The objective of this study was to assess the outcome of arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in a consecutive series of patients. MATERIALS AND METHODS A retrospective review of 36 patients with lateral ...

OBJECTIVE The purpose of this prospective case series was to describe the outcomes of a set of rock climbers with lateral epicondylalgia (LE) treated with manual therapy directed at the cervical spine, elbow, and wrist as well as trigger point (TrP) dry needling and kinesio tape. METHODS Nine consecutive rock climbers presenting to physical therapy with a diagnosis of LE were included. At bas...

Introduction Variations of human hand extensor muscles have been previously described [1]. The extensor medii proprius (EMP) is one such variation reported with an incidence ranging from 0.8% (2 out of 263 specimens) [2], to 10.3% (6 out of 58 dissected hands) [3]. The EMP often co-exists with the extensor indicis muscle or its variant, the extensor indicis proprius on one hand or both hands [1...

INTRODUCTION Second-harmonic generation microendoscopy is a minimally invasive technique to image sarcomeres and measure their lengths in humans, but motion artifact and low signal have limited the use of this novel technique. METHODS We discovered that an excitation wavelength of 960 nm maximized image signal; this enabled an image acquisition rate of 3 frames/s, which decreased motion artif...
