[Soft tissue and bone defects of the tibia. Treatment with pedicled muscle transfer and a microvascular anastomosed myocutaneous flap].

The free tissue transfer by microvascular anastomoses has opened new dimensions in reconstructive surgery. However a free microvascular myocutaneous flap should only be used in case of a local pedicled flap being impossible. In treating complicated defects of soft tissue and bones a clear cut gradation of therapeutic steps has to be observed: 1. control of wound infection, 2. wound debridement, 3. soft tissue repair, 4. bone reconstruction.

[Reconstruction of combined soft tissue and bone defects of the lower leg].

In 7 patients with traumatic defects of the soft parts and bone of the lower leg the authors transplanted a free latissimus dorsi flap with microvascular connection. The surgical technique and approach are described. Secondary autologous spongioplasty. The results are stated. The method is a safe one.

[Microsurgical aspects of wound healing in the extremities (author's transl)].

Microsurgical operative technique made it possible to restore the arterial and venous blood flow or to improve it, even for a relatively small tissue area, and to re-innervate these fabrics. Reconstruction of lymphatic drainage is technically possible, but quite a number of problems remain to be solved before further clinical application is possible. Grafting of a microvascularly pedunculated bone chip is superior to the bone chip without primary vascularisation, but will offer advantages over grafting of spongiosa in very rare cases only. At the present moment it is not yet possible to safely assess the influence exercised by re-innervation on wound healing.

[Microsurgical plastic reconstruction of the explosion-damaged hand].

During the last two years, 16 severe explosion injuries of the hand have been treated with plastic microsurgery in our hospital. The injury had arisen in seven cases from the mixture sugar + sodium chlorate (C12H22O11 + NaClO3). This substance mixture may already be caused to explode by slight vibrations and the warmth of the hands. In explosion injuries, there is mechanical, chemical and thermal tissue damage. The postoperative course is therefore complicated in almost all cases. However, by meticulous removal of the disseminated foreign particles, excision of necrotic tissue and extensive reconstruction of the interrupted vascular and nerve supply, it is possible in a few cases to preserve functionally important parts of the hand. Later plastic procedures are made more difficult by tissue fibrosis and foreign body granulomas.

[Experimental studies on the pathophysiology of knee ligament lesions (author's transl)].

The cruciates and the collateral ligaments of the knee compare well with a crossed four-joint chain. In surgery of the ligamentous lesions of the knee it is essential to reinsert the ligaments exactly at their anatomic position. Studies of cadaver knees have demonstrated that the medial collateral ligament ensures medial rotational stability to a greater degree than the meniscofemoral and meniscotibial bands. In every stage of medial and anterior ligamentous lesions, external rotation in 90 degrees of flexion shows the same amount of anterior laxity of the medial tibial condyle as the test of Slocum. In contrast to Nicholas the pivot point in anteromedial complex instability is situated posterolaterally.
