OBJECTIVE Referred pain and pain characteristics evoked from the extensor carpi radialis brevis, extensor carpi radialis longus, extensor digitorum communis, and brachioradialis muscles was investigated in 20 patients with lateral epicondylalgia (LE) and 20-matched controls. METHODS Both groups were examined for the presence of myofascial trigger points (TrPs) in a blinded fashion. The qualit...

A 52-year-old man had a 1-month history of bilateral wrist pain. Although the patient participated in weight-lifting activities, his symptoms began shortly after he mowed the grass. Physical examination revealed bilateral and painful fusiform swelling at the distal forearms (pictured) with crepitus noted at the right distal forearm. Two variants of the Finkelstein test were performed, the resul...

[Purpose] This study measured %isolation and investigated whether it shows a difference between the presence and absence of wrist joint restriction, as well as changes in muscle activity patterns. [Methods] Twenty subjects performed upper extremity functional movement in the Manual Function Test (MFT) with and without wrist restriction, and the muscle activities of the trapezius, middle deltoid...

PURPOSE Wrist joint-leveling procedures for decompression of the radiocarpal and ulnocarpal joints are accompanied by the risk for subsequent disorders of the adjacent distal radioulnar joint (DRUJ). This study evaluated the dynamic change of the pressure pattern at the DRUJ after joint-leveling procedures. METHODS Thirteen fresh-frozen adult cadaveric upper extremities were used. A segment o...

Tendon autografts play an important role in upper limb reconstruction and a working knowledge of tendon autograft options is essential for the surgeon. Although palmaris longus is often the first choice, other options like plantaris, extensor Hallucis longus, flexor carpi radialis are readily available. Advantages of autografts include easy availability, satisfactory biomechanical properties an...

The design of the wrist extensor muscles was studied using a combination of intraoperative laser diffraction and biomechanical modelling of data obtained from human patients and previously published data. Intraoperatively, the change in sarcomere length per degree joint angle rotation (i.e. dSL/d omega) was measured as the wrist was moved from neutral to full flexion in both the extensor carpi ...
