[Microvascular complications following replantations and revascularisations].

Purpose/background: What are the options for early diagnosis, treatment and prevention of the occlusion of microvascular anastomosis after replantations? METHOD AND (CLINICAL) MATERIAL: This is a retrospective analysis of 336 cases involving primary microvascular repair after an injury between 1984 and 2000. In 272 cases this was a revascularisation and in 187 a replantation. In 23 cases the vascular anastomosis was located proximal to the wrist (macroreplantations) and 313 times distal to it (microreplantations/-revascularisations).

[Fixation of periprosthetic femur fractures with the less invasive stabilization system (LISS)--a new minimally invasive treatment with locked fixed-angle screws].

The Less Invasive Stabilization System (LISS) is a minimally invasive technique indicated for fixation of periprosthetic fractures. This new system allows percutaneous placement of cortical-shaft screws and fixation of the fracture with fixed-angle locked screws with minimal surgical exposure of the mostly osteoporotic bone and without disturbance of the existing total joint replacement. Immediate range-of-motion exercises are begun postoperatively.

[Late results following avulsion injuries of the thumb].

Out of the 127 amputated thumbs replanted at our unit during the last 15 years, there were 27 avulsion injuries. The average age of the 24 male patients was 33 years, that of the three female patients was 34 years. 70 % of the injuries were occupational accidents.
