Forearm reconstruction after loss of radius: Case report

Abstract

Introduction. Osteomyelitis of the radius resulting in the radial clubhand is a very rare condition and few studies have been published about its prognosis and treatment. Case Outline. This is a case report of hematogenous osteomyelitis of the radius with a complete loss of the radius leaving only the distal radial metaphysis to carry the carpus. In order to achieve best functional results, four-step operative protocol was performed for reconstruction; lengthening of the forearm by external fixator, radioulnar transposition to create a one-bone forearm, plate removal and transposition of brachioradialis to the extensor pollicis longus as well as proximal row carpectomy. After nine years of the last operation, the function of the elbow and hands is good with acceptable cosmetic result. The forearm is 5 cm shorter and there has been a persistent mild limitation of palmar flexion. Conclusion. Creation of the one-bone forearm normalizes the elbow and wrist function, corrects forearm malalignment, and improves forearm growth potential.
