Surgical Corection of Congenital Proximal Radioulnar Synostosis Using Double Osteotomy Technique.

Condition(s) studied

Investigational drug(s) / intervention(s)

derotation osteotomy utilizing Kirschner wires for the correction of congenital proximal radioulnar synostosis: The level of distal radial and proximal ulnar osteotomies is determined under C- arm. A k-wire is inserted in the outer border of the metaphysis of the radius distal to the level of the osteotomy, engaging and transfixing the radioulnar joint, small skin incision is made over the dorsal aspect of the forearm at the level of distal radial osteotomy, dissection of subcutaneous tissue with good exposure of the extensor tendons, transverse osteotomy is done using 2.5 mm drill bit and small sharp osteotme, allowing derotation movement of the distal part of the radius using the k-wire. Another small skin incision is made over the level of proximal ulnar osteotomy, dissection of subcutaneous tissue, another ulnar transverse osteotomy is done distal to the level of the proximal radioulnar synostosis. Derotaion of the forearm is adjusted in the functional position of the forearm in around (10˚:20˚supination), wound closure using absorbable Vicryl sutures. Above elbow cast is used f

Study summary

The purpose of the present study is to asses and maintain derotation osteotomy for treating proximal radioulnar synostosis.

Primary outcome measure(s)

• surgical derotation osteotomy utilizing Kirschner wires for the correction of congenital proximal radioulnar synostosis — one year
  Proximal radio-ulnar synostosis is a skeletal malformation of the upper limb characterized by bony fusion at the proximal aspect of the radius and ulna. The proximal third is considered the most common site of the radio-ulnar synostosis. This deformity is found mainly in preschool-aged children (4:8 years old), The proximal radioulnar synostosis was first described by the Dutch anatomist Eduard Sandifort in 1793¹. The ideal treatment for congenital radioulnar synostosis aims to restore rotational function and prevents the recurrence of the bony bridges. we aim to do surgical osteotomy and correct the synostosis to restore the function of the upper limb and will be assessed by geniometry , clinical and functional outcomes .
