INTRODUCTION Infected nonunion of radius and ulna are rare but difficult problems to deal. We report a case of successfully managed infected non-unonion of forearm bones and the reasoning behind strategy of approach to the case. CASE REPORT 42 year old female presented with history of closed forearm fracture three months back for which she was operated with open reduction and internal fixatio...

Regulation of load-induced bone formation is considered a local phenomenon controlled by osteocytes, although it has also been hypothesized that functional adaptation may be neuronally regulated. The aim of this study was to examine bone formation in multiple bones, in response to loading of a single bone, and to determine whether adaptation may be neuronally regulated. Load-induced responses i...

OBJECTIVE To identify the anatomic characteristics of the pronator quadratus (PQ) muscle and the entry zone (EZ) of the anterior interosseous nerve (AIN) to this muscle by means of cadaver dissection. METHODS We examined the PQ muscle and AIN in 20 forearms from 10 fresh cadavers. After identifying the PQ muscle and the EZ of the AIN, we measured the distances from the midpoint (MidP) of the ...

INTRODUCTION Despite the multitude of studies for the treatment of non-unions, no clear criterion has been established for treating a fracture of non-union. Non-union of radius and ulna produces a discrepancy in length which must be restored for adequate rotation and function. Nicoll described a technique of bridging gaps in long bones with solid blocks of cancellous bone and fixing the fragmen...

BACKGROUND We report our experience with the use of a full-thickness corticocancellous iliac-crest graft, 1 to 5 centimeters in length - to treat established nonunion of the radius and/or ulna. MATERIAL AND METHODS The technique was used in 14 patients (11 men and 3 women, age 19 to 59). The graft application was combined by rigid fixation with intramedullary locking nail, permitting early ac...

This study is to explore the influence of palmar lateral joint capsule ligament complex on dorsal stretching stability wrist and analyze its biomechanical principle, so as provide reference for clinical medicine. To characteristics posterior complex, in this we selected 8 freshly donated body upper limbs including 5 left ones 3 right research objects. By cutting off forearms hand soft tissues l...

A rare case is reported of a Monteggia equivalent injury where a dislocation of the radial head is associated with fracture of the distal third of the radius and ulna. The mechanism, treatment and outcome are described.

Failure of the distal radioulnar joint leads to significant dysfunction of the upper limb. Numerous surgical procedures have been suggested to address this problem. In degenerative arthritis, joint instability and ulnar stump dislocation after salvage procedures such as Darrach distal resection or Sauvé-Kapandji distal fusion, an ideal solution may not be available. The ultimate option to resto...
