[Microangiographic evaluation of vascular supply of the medial collateral ligament of the knee joint].

Because the vascularization of ligaments is an important factor in ligament healing we wanted to examine the vascularization status of the medial collateral ligament of the knee. The type of vascularization was examined by microangiographie of 21 postmortem preparations. We could observe a vascularization from the proximal end of the ligament by one or two major vessels in all cases.

[Ligamentization as an explanation for the stability of periosteal flap repair in the replacement of the fibular ligament system].

The gold standard in the operative treatment of chronic insufficiency of the lateral ligaments of the ankle joint is replacement with a tendon (tenodesis). The disadvantage of this method is limitation of movement. The results of the replacement of ligaments with a periosteal flap are similar to the results after tenodesis, but the rate of complications is significant lower.

[Injuries in horseback riding--incidence and causes].

This article presents the examination of 78 accidents in horseback riding, referring to their origin and kind of injury. It was found that 76% of all injuries did not occur during the active phase of riding, but in the time just before and right after it. Children without any experience in horseback riding were most susceptible to injuries.

[Biomechanics of the knee joint after meniscus resection. Stress analysis of the cadaver knee].

Load bearing analysis has been performed in cadaver knees after different types of inner meniscus resection in extension and in 30 degrees and 60 degrees flexion. Contact areas, mean and maximum pressure differences and load flow changes were measured in the medial and lateral compartment of the knee. The investigation led to following findings: After posterior meniscal tear the resection of the tear with marginal smoothing is followed by a minimum of parameter deviation.

[Prognostic improvement by R1 and R2 lymphadenectomy in stomach carcinoma].

In 1986 systematic R2 lymphadenectomy was introduced into the surgery for gastric carcinoma in our institution. In an historic analysis 381 patients of the years 1980-1992 were investigated. The effect of R2 lymphadenectomy was studied after R0 resection and exclusion of inhospital mortality.
