    Notes: Abstract We investigated retrospectively 132 cases of open wedge high tibial osteotomy using an external fixation device, concentrating on the rate of neurological complications. One group of patients underwent surgery according to the conventional technique (n=89). The rate of transient neurological complications was 15.7%; 7 months after surgery the rate of persistent deficits was 12.4%. For the second group (n=43) a modified surgical technique was used that lowered the complication rate significantly (transient deficits 14%, persistent deficits 4.7%). In the modified technique the osteotomy is not performed in the conventional way using an oscillating saw but through consecutive drill holes of increasing diameter followed by osteoclasis. The lower complication rate in the second group is mainly due to the less extensive approach that leads to a smaller number of postoperative tibialis anterior syndromes (type B lesion). No differences were found with type C lesions (extension deficit of D1). No complete peroneal nerve palsy (type A) occurred in either group. We conclude that the reduction of neurological complications in group 2 is related to the less extensive approach of the proposed technique.

    Description / Table of Contents: Abstract. Retrospective analysis of 30 patients with pathological fracture out of 336 patients with primary malignant bone tumors should demonstrate the influence a pathologic fracture and the form of surgical therapy have on the survival rate. In 25 out of 30 patients a fracture led to diagnosis of the disease. Pathological fractures occurred cumulatively by malignant fibrous histiocytoma of the bone and in tumor stages IIb and III. Surgery was performed on 26 out of 30 patients (12 ablative therapies, 14 reconstructive therapies). The mortality risk for patients with pathological fractures was more than double the risk for patients without pathological fractures (P = 0.0062). When performed correctly, reconstructive therapy does not influence the survival rate.
    Notes: Zusammenfassung. Die retrospektive Analyse von 30 Patienten mit einer pathologischen Fraktur aus einem Gesamtkollektiv von 336 Patienten mit primär malignen Knochentumoren soll klären, welchen Einfluß das Auftreten einer pathologischen Fraktur und die Form der chirurgischen Therapie auf die Überlebenswahrscheinlichkeit haben. Bei 25 von 30 Patienten führte die Fraktur zur Diagnose des Tumorleidens. Pathologische Frakturen traten gehäuft bei malignen fibrösen Histiocytomen des Knochens und bei Tumoren im Stadium IIb und III auf. 26 von 30 Patienten wurden chirurgisch therapiert (12 ablative Verfahren, 14 extremitätenerhaltende Verfahren). Das Sterberisiko von Patienten mit pathologischer Fraktur war gegenüber den Patienten ohne pathologische Fraktur mehr als verdoppelt (p = 0,0062). Bei Einhaltung adäquater Resektionsgrenzen ist die Überlebenswahrscheinlichkeit von Patienten mit einer pathologischen Fraktur durch extremitätenerhaltende Rekonstruktionsverfahren nicht beeinflußt.
