Review[Transfer of the posterior tibialis tendon to restore an active dorsiflexion of the foot].
After lesions of the peroneal nerve or damage of the tibialis anterior muscle a lack of active dorsiflexion leads to a drop foot deformity. Ober (1933) described a transfer of the posterior tibialis tendon to the dorsum of the foot to restore active extension of the foot. The aim of this retrospective study was to evaluate the results of this method and to compare our results with those in the literature. ⋯ The Stanmore score revealed an average of 62 points with an excellent result in 2, a good result in 5, a fair result in 2 and a poor result in 5 patients. Transfer of the posterior tibial muscle to restore active dorsiflexion of the foot is a therapeutic option. As it is known from the literature objective results were mostly fair, but there was a high degree of satisfaction among the patients.

Review Case Reports[Coronal fracture dislocation of the hamate and the base of the fourth metacarpal bone: a rare form of carpometacarpal injury].
Fractures of the hamate body and the base of the fourth metacarpal bone in the coronal plane with or without a dislocation of the base of the fifth metacarpal bone are rare. Clenched fist punches are considered to be the main cause. The diagnosis of the fracture dislocation is often missed on routine radiographs. ⋯ Screw or K-wire fixation with postoperative cast immobilisation for 6 weeks and consecutive hardware removal has been found to result in excellent clinical and radiological outcomes. This study presents 2 cases of coronal fractures of the body of the hamate and the base of the fourth metacarpal bone with subluxation of the hamatometacarpal V joint. Anatomy, epidemiology, classification, mechanism, clinical symptoms, diagnostic features, and therapy options for these injuries are discussed.

Review Case Reports[Combination of ulnar head fracture with undisplaced radial neck fracture: case report and review of the literature].
We present a case of a to our knowledge never described before combination of a displaced ulnar head--with an undisplaced radial neck fracture associated with a clinical instability of the distal radioulnar joint (DRUJ). We discuss the management of our atypical case and review the literature.

In critical size bone defects resulting from failed fracture healing or pseudarthrosis surgery is usually required. In this context, autologous bone grafts and callus distraction represent the gold standard, while sometimes even vascularised bone transfer is mandatory including microsurgical techniques. The availability of donor sites for such procedures is limited and the resulting morbidity significant. ⋯ In addition, they may act as a delivery vehicle for growth factors, antibiotics or cells. Their main limitation has been the lack of an intrinsic blood supply, limiting the potential for transplantation. This review provides an overview of matrices, cells and other therapeutic substances in the field of bone tissue engineering.

Adipose-derived stem cells (ASCs) can be isolated from human adipose tissue with the exceptional potential for differentiation into mature adipocytes. Utilization of this system is very promising in developing improved techniques to repair soft tissue defects. Current reconstructive procedures, especially after trauma and oncological surgery, transfer autologous soft tissue grafts having limitations. ⋯ This review will discuss the relevant properties of human adult adipose-derived stem cells for the regeneration of adipose tissue. Discussion will focus on the biology of ASCs, cell delivery vehicles/scaffolds useful in applying ASCs as a therapy, and suitable IN VIVO animal models for studying adipose tissue engineering. Also included is a description of the current clinical studies with ASCs in Europe and Asia.
