The reconstruction of the upper limb often requires functioning muscle units to be transferred. In severe injuries such as crushed forearms, Volkmann's ischaemia, brachial plexus lesions and tetraplegia, there is often a paucity of available muscle units for reconstruction. One avenue, which is relatively unexplored, is the use of split pedicled muscle transfers. The prerequisite for a split mu...

Ulnar nerve compression at the elbow can occur at any of five sites that begin proximally at the arcade of Struthers and end distally where the nerve exits the flexor carpi ulnaris muscle in the forearm. Compression occurs most commonly at two sites-the epicondylar groove and the point where the nerve passes between the two heads of the flexor carpi ulnaris muscle (i.e., the true cubital tunnel...

This study reports an objective assessment of postoperative function of 11 triple transfers for high radial palsies, using pronator teres for wrist extension, flexor carpi ulnaris for finger extension and palmaris longus for thumb extension. The mean follow-up was 3.3 years. Assessment was done by recording the active ranges of wrist motion, grip strength, wrist and finger strength and work sim...

This study reports a case of acute calcific tendinitis of the flexor carpi ulnaris in a 64-year-old woman. She presented with symptoms of acute ulnar nerve compression mimicking a volar compartment syndrome. Owing to rapidly progressive symptoms, emergency surgical exploration was carried out. Intra-operatively a large mass of calcium phosphate carbonate was noted in association with the flexor...

The extensor carpi ulnaris (ECU) muscle plays a key role not only in the active movements of wrist extension and ulnar deviation but also in providing stability to the ulnar side of the wrist. Its position relative to the other structures in the wrist changes with forearm pronation and supination. As such, it must be mobile yet stable. The ECU tendon relies on specific stabilising structures to...

Recently the Sauve-Kapandji (S-K) procedure has become popular for the treatment of various distal radioulnar joint (DRUJ) disorders. However, some complications, especially pain over the proximal stump of the ulna due to instability of the ulna have been reported in more recent follow-up studies. To prevent the occurrence of this pain, we devised a modified S-K procedure, which we called the s...

The aim of this study was to investigate rider muscle activity in relation to horse movement. Electromyographic (EMG) activity of 12 upper-body muscles was recorded simultaneously with the horse’s footfall timing for six riders, riding the same horse at trot. Data for five strides were analysed for each rider. Rectus abdominis, upper trapezius, middle trapezius, flexor carpi radialis, biceps br...

The records of 110 cases of ulnar neuritis in 100 patients have been reviewed an average of 4.4 years after anterior transposition, or release of the aponeurosis. Seventy of the patients were reviewed personally. In over half the cases no precipitating cause was apparent. At operation the nerve was constricted by the flexor carpi ulnaris aponeurosis in fifty cases but in twenty-five no abnormal...
