Background: The Extensor Carpi Radialis Longus (ECRL) and the Extensor Carpi Radialis Brevis (ECRB) are muscles of the posterior forearm compartment. variations in this area of the forearm are common and are usually diagnosed during surgery. Sometimes these variations are symptomatic and can be helpful in clinical procedures such as surgery. Diagnosis and identification of abnormalities can be ...

This review describes a series of experiments in which sarcomere length was measured in human wrist muscles to understand their design. Sarcomere length measurements were combined with studies on cadaveric extremities to generate biomechanical models of human wrist function and to provide insights into the mechanism by which wrist strength balance is achieved. Intraoperative measurements of the...

Tennis elbow is a common cause of pain and disability. It is more frequently seen in non-athletes, with a peak incidence in the early fifth decade on a nearly equal gender basis. Degeneration of the tendon of extensor carpi radialis brevis is believed to be the most common cause. Non-operative treatment is successful in effecting a resolution of symptoms in 90% of the patients. The remaining 10...

The objective of the article is to evaluate the impact of the friction force mouse-pad in the contraction level of the forearm muscles M. extensor carpi ulnaris, M. extensor digitorum and M. extensor carpi radialis longus. A standard protocol of mouse movements was performed involving horizontal, vertical and diagonal mouse displacements drag-anddrop type. The operators were instructed to execu...

Different surgical techniques exist to treat lateral epicondylitis. In most techniques, release of the common extensor origin is performed adjacent to the humeral epicondyle. The purpose of the present study was to assess the outcome of transverse sectioning of the intermuscular septum and the aponeuroses of the extensor carpi radialis brevis and extensor digitorum communis, 3 to 5 cm distally ...

Extensor carpi radialis brevis (ECRB) sarcomere length was measured in seven patients using intraoperative laser diffraction. Sarcomere length was measured with the forearm in one of four positions: wrist in neutral with regard to radial-ulnar deviation and forearm in neutral rotation, wrist in ulnar deviation and forearm in neutral rotation, wrist in neutral and forearm in pronation, and wrist...

The purpose of this study was to determine the interrepetition and interoccasion generalizability of grip strength measurements in patients with the diagnosis of proximal extensor carpi radialis brevis tendinitis. Thirty-five consecutive patients (mean age = 44.5 +/- 8.6 years; mean duration of symptoms = 3.9 +/- 3.5 months) fulfilling the eligibility criteria participated in the study. Measure...

We welcome the opportunity to respond to the informative letter regarding the terminology of concentric and eccentric. We certainly agree that it is exceedingly important to be as precise and accurate as possible when using these and any scientific terminology. The authors of the letter astutely point out the difference in terminology between movement of a single muscle compared with movement o...

BACKGROUND Tennis elbow is a common elbow pathology typically affecting middle-aged individuals that can lead to significant disability. Most cases resolve within 2 years of symptom onset, but a subset of patients will develop persistent symptoms despite appropriate conservative management. There are several surgical approaches used to treat chronic tennis elbow, with arthroscopic surgery becom...

conclusions of the open reductions and internal fixations, 11 (92%) were successful and patients made a full recovery. conservative management was unsuccessful in 4 cases; one patient required surgery for metacarpal boss, one patient had retraction of the tendon at one week follow up and another had weak flexion of the wrist. we recommend open reduction and internal fixation for these injuries....
