[Compression syndromes of the shoulder and their differential diagnosis].

Compared to other painful conditions on the shoulder suprascapular nerve entrapment is an obscure and uncommon syndrome causing severe shoulder pain and disability, and is easily cured if only it is recognized. The condition was described by Thompson and Kopell in 1959, Schilf reported a case of isolated suprascapular entrapment in 1952. The nerve passes through the suprascapular notch, the roof of the notch is formed by the transverse scapular ligament. The shape of the suprascapular notch may be guilty for entrapment symptoms. Suprascapular nerve compression may result of acute trauma, of transmitted forces, fracture of collum scapulae, of kinking or traction of the nerve over the edge of the foramen, of sling effect, of compression by ganglia, or its cause may be idiopathic. The hallmark of suprascapular nerve entrapment is a deep and poorly delineated pain, localized to the posterior and lateral aspect of the shoulder. Atrophy and weakness of the supraspinatus and infraspinatus may be noted. Adduction of the extended arm across the body tenses the nerve, increasing the pain. Blocking the nerve by local anesthetic a dramatic, but not long lasting pain relief may be achieved. Electromyographically a decrease in the amplitude or marked polyphasicity of evoked potentials is significant as well as an increased latency time, indicating an impaired conductibility. A surgical release is indicated in case of constant pain and pathological changes of EMG-patterns. From a postero-superior approach decompression of the nerve is performed by simple removal of the transverse scapular ligament.

[Compression syndromes of the ulnar nerve and median nerve in the area of the hand].

Carpal tunnel syndrome occurs very frequently and results from synovial tissue proliferation caused by a variety of events. Morbidity can be determined by detailed neurological examination and treatment depends on the extent of the distal latency. During the operation it is important to pay close attention to the various nerves and to proceed as carefully as the individual situation requires. The success rate also depends on adequate aftercare and follow-up. In the case of Guyon syndrome, operation is always indicated, with the goal being decompression and to search for the cause of the compression. The results are also excellent.

[Expanded diagnosis of fractures of the wrist joint].

The procedure and techniques used to diagnose carpal fractures can be difficult. Therefore, the authors have developed a new apparatus to help make the roentgenologic diagnosis. A reproduction of the diagnosis is possible at anytime. During the last two years many fractures have been discovered by this new apparatus.

[Computerized tomography study in carpal tunnel syndrome].

A comprehensive study shows that the computer tomogram in proven carpal tunnel syndrome displays changes in the structures in the carpal tunnel like edema or fibrous modifications of the synovium in a clear form. Tumors and bone constrictions are also demonstrated by the help of the tomogram. In the same way, thickening of the flexor retinaculum or its displacement causing compression of the median nerve can be seen. Postoperatively we can differentiate between good and poor results. Nevertheless, we do not think the computer tomogram should be part of the standard examination of the carpal tunnel syndrome.

[Indications and results of corrective radius operations].

Posttraumatic malunion usually results from incorrect treatment of a Colles or Smith fracture. Chronic pain, limited motion and impaired power can be avoided and the cosmetic appearance of the hand improved, by restoration of the functional anatomy of the wrist. The malalignment is corrected by open wedge osteotomy of the distal end of the radius. A small iliac cortico-cancellous bone graft is inserted at the osteotomy site. By using this technique, it is usually possible to avoid additional resection of the distal ulna. The surgical approach dorsal or palmar is determined by the type of dislocation. The small T-plate offers a stable fixation. The results are illustrated by 41 cases.

[Syndactylia results].

During the years 1960-1980 42 patients with syndactyly were treated at the Department for Handsurgery of the University of Munich. In addition to the conventional classification and in regard to the criteria for operative management, we stress the difference between the simple and the more complex forms of syndactyly as well as those cases in which the syndactyly is part of a syndrome. There was a relation of 1:1 between the simple and the 'complex' syndactyly. The results of former and modern operative management are reviewed and the value of some special methods is pointed out.

[Pilous nevi of the hand].

Pilous nevi of the hand should be treated both to prevent cosmetic and functional disorders and because they can degenerate. In the first months of life a dermabrasio can be performed, later excision and skin-grafting is necessary. A case of pilous nevus involving nearly the whole right hand, which had been treated ten years previously, is reported.

[Sonography of Achilles tendon rupture].

The authors report on the possibility of demonstrating Achilles tendon rupture via ultrasound. The characteristics echo pattern in the healthy (normal) Achilles tendon, and the sonographic criteria of the various types of rupture, are described. Sixteen patients with clinically suspected subcutaneous Achilles tendon rupture were examined using a 5 MHz transducer. In ten cases, an Achilles tendon rupture could be demonstrated, all of which were confirmed by surgery. In six patients, rupture could be excluded; after renewed clinical examination, these cases were successfully treated as distorsions. In clinically evident rupture of the Achilles tendon, ultrasound examination may not only provide further diagnostic information on the localisation and type of rupture, but also on the condition of the tendon at the site of rupture. It can also supply pointers regarding secondary changes, such as haematoma, oedema, and deviations in the position of the Achilles tendon. In doubtful cases, ultrasound can be a helpful additional diagnostic method.

[Epicondylitis humeri lateralis, operative technique and results (author's transl)].

Epicondylitis humeri lateralis is caused by excessive strain on the extensors of the forearm. Chronic inflammation of the epicondylus humeri lateralis and irritation of sensitive fibres of the radial nerve result. The pain can be eliminated by Hohmann's operation on the epicondylus humeri lateralis, with complete separation of the forearm extensor roots. Additional denervation of the epicondylus humeri lateralis (A. Wilhelm's method) eliminates the pain sensations due to the disease by interrupting the sensitive nerve fibres of the N. radialis. These two operations are complementary and a combination of both increases the success rate to 90%.
