[Principles and results of treatment of forearm shaft fractures with Rush pins stabilization]. / Zasady i wyniki leczenia zlaman trzonów kosci przedramienia zespolonych pretami Rusha.

Rush pins are used for stabilization of forearm shaft fractures after surgical reduction. The pins are bent intraoperatively to conform to the natural curvature of the radius. Introduction of the pin into the radius takes place between the extensors of the index, the extensor digitus communis and the extensor pollicis longus. Safe and equally effective introduction of the pins is also possible through the olecranon when treating fractures of the proximal part of the ulna or from distal end in fractures of the distal half of the ulna. The clinical material in this paper consisted of 21 patients treated surgically with Rush pins because of fractures of the forearm. In two cases primary consolidation was not achieved. Union of the fracture did occur after periostage and iliac bone grafting. Long term follow-up of 19 patients demonstrated a full range of motion in the involved extremity in 14 cases. Limited rotation of the forearm was noted in 5 patients.

Types and causes of renal osteodystrophy in chronic (3-12 years, hemodialysed patients are presented. Tissue weakening due to osteodystrophy resulted in 6 extensor mechanism lesions in 4 patients. Two quadriceps tendon avulsions, 1 patellar fracture, 2 patellar tendon avulsions involving the tip of patella and 1 patellar tendon rupture occurred. Pathomorphology and course of surgical treatment has been discussed. Good functional results have been achieved.

A case of patient with flexor digitorum profundus tenodesis at the site of metaphyseal fracture of the radius is presented. The open fracture occurred when the patient was 11 years old and was treated elsewhere with plaster of paris. Progressive flexion contracture of the middle, ring and little finger was treated surgically 7 years later. Full extension and good hand function has been achieved.
