In distraction osteogenesis, different factors influence quality and quantity of bone formation. These factors are rigidity of fixation, frequency, and velocity of transport; and integrity of periosteum, endosteum, and intramedullary vascularization. Little data are available on forces related to distraction osteogenesis and limb lengthening, and no data on(More)
Shoulder joint infections are severe pathological conditions. Since the success of therapy is decisively dependent on early treatment, if joint infection is suspected, the patient should be hospitalized immediately. Characteristic suspicious features are extremely severe shoulder pain, adoption of a pain-relieving posture, and severe malaise. The diagnosis(More)
Ziel der prospektiven Therapiestudie war es, die postoperativen Ergebnisse nach primärer oder frühsekundärer arthroskopischer Kapsel-Labrum-Refixation bei traumatischer anteriorer Schultererstluxation zu überprüfen. Die Patienten zwischen 16 und 30 Jahren wurden innerhalb von 2 Wochen oder in der 7. bis 12. Woche arthroskopisch stabilisiert und(More)
The treatment of intra-articular fractures of os calcis has so far been controversial. For reconstruction of static and dynamic conditions of the foot, complex deformities must be corrected. Besides intra-articular malformation of the talocalcaneal joint that is supposed to lead to posttraumatic arthritis, there are malalignments like lateral displacement,(More)
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(More)
A rare case of median nerve compression syndrome outside the carpal tunnel in the distal forearm is reported. A 21-year-old man suffered while working from symptoms of temporary median nerve compression in both forearms; this was caused by hypertrophy of reversed palmaris longus muscles. Resection of the abnormal muscle bellies relieved the symptoms(More)
Whether conservative or operative management is selected for intra-articular fractures of the os calcis depends on subjective factors and on the surgeon's experience. There is no classification available that allows ranking of such fractures according to the extent of destruction and the degree of dislocation at the same time. CT scans of 44 calcaneal(More)
PROBLEM The vascularity of the articular fragment is of key importance for the final outcome in three- and four-part fractures of the humeral head. Displacement of the articular segment may compromise the arterial blood supply to the humeral head and result in avascular necrosis. There is still controversy as to whether three-and four-part fracture(More)
Replacement of the fractured humeral head with a modular prosthesis. The procedure aims at an adequate reconstruction of shape and function of the shoulder. Displaced three- and four-part fractures of the proximal humerus that cannot be reduced and internally fixed. Fracture can be reduced and adequately internally fixated. Noncompliant patient. In(More)
