Pathological results on plain radiographs and cineradiography reliably indicate the presence of SLD after wrist trauma. Although non-conclusive, a negative dynamic study markedly reduces the pre-test probability of disease. Both methods remain key elements of primary diagnostic strategies for suspected traumatic SLD, and may facilitate the selection of additional tests.

Vascularized bone transfer is increasingly recognized as a very useful and versatile technique for reconstructing large bone defects. It is especially indicated in patients with challenging conditions, such as nonunions, postoncologic resections, severe trauma, and congenital defects. With increasing experience of reconstructive surgeons, improved microsurgical techniques, and more enhanced flaps, the failure rate of free flaps has been reduced in the last decades. Especially, the early-postoperative period is decisive in the outcome of surgery. Several techniques have been described for monitoring the postoperative viability of microsurgical free vascularized graft, and their sensitivity and reliability continues to be the object of animal experiments and clinical trials. The qualities of an optimal monitoring device should be objective, continuous, noninvasive, safe, reproducible, easily managed, and interpretable for the nursing staff, inexpensive, and a clear indicator of changes in arterial and venous circulation. Presently, no one neither fulfills all of the criteria completely nor is uniformly accepted. In this article, relative advantages and disadvantages of these various postoperative monitoring techniques are discussed.

Management of soft tissue ruptures of extensor tendon lesions of zone I is both difficult and controversial. Because of their superficial position already minor injury can be sufficient for laceration. Furthermore many authors are convinced of an easy way of diagnosing and repairing extensor tendon ruptures in comparison to injuries of the flexor tendons. However, this injury can cause significant hand dysfunction and has to be treated with attention in order to provide the best possible outcome for the patient. Therefore we try to evaluate the common treatment procedures and to give guidelines for management of this injury.
