The authors examined 34 tendons under the electron microscope, excised within 48 h after rupture of the tendons. The tendons did not exhibit any signs of inflammation or lipomatosis, but fine-structurally marked hypoxic alterations in the tenocytes could be seen. The degenerative (hypoxic tendinopathy appears in three phases, and the hypoxic lesions of the tendon occur at multiple foci or diffusely, and the various phases can exist simultaneously.

The gastrocnemius myocutaneous flap (GMF): an alternative method to repair severe lesions of the leg.
A short review of the various methods of closing skin defects associated with severe injuries of the leg raised the question for using a myocutaneous flaps and particularly a gastrocnemius flaps. The surgical technique is described and the versatility of the flap is demonstrated with several examples and discussed showing how both the medial and the lateral gastrocnemius flap, can be used as a pedicle as well as a free flap, ipsi- and contralaterally.

Case ReportsDiaphyseal fractures of both bones of the lower leg with associated injury of the ankle mortise.
Fractures of both bones of the lower leg may be accompanied by a disruption of the mortise with a shortening of the fibula. This combination was observed in four cases reported in this paper. ⋯ Any shortening of the fibula should be corrected surgically, preferable at the time of injury. Malunion should be treated by corrective osteotomy.

New clinico-pathophysiological studies on the bone cement implantation syndrome.
Implantation of endoprostheses with bone cement is followed by alterations of the circulation. Intoxication, caused by the monomer of bone cement or pulmonary embolism by intramedullary contents constitute the two mostly accepted pathophysiological hypotheses. Because of the lack of pulmonary and circulatory physiological data a clinical decision concerning the value of the hypotheses was not possible until now. ⋯ The device allowed a high rate of data retrieval. The bone cement implantation syndrome reveals itself as cardiorespiratory sequelae of a disseminated pulmonary embolism which is originating in intramedullary contents, squeezed intravasal. Usual prophylactic methods are revisited.
