Use of a Bone Block Graft from the Iliac Crest with Rigid Fixation to Correct Diaphyseal Defects of the Radius and Ulna

Abstract

We report our experience with the use of a bone block graft from the lilac crest to correct diaphyseal defects of the forearm bones. The technique was used in 12 patients (ten men and two women, average age 29 years) for defects resulting mainly from either closed or compound fractures, which later developed infection and bone tissue loss. The average dimensions of the graft required to correct the defect was 3.5 × 1.8 cm. The graft application was combined with rigid fixation with an AO 3.5 mm DCP plate, permitting early active motion. The graft incorporated without any additional grafting procedure in ten cases within 17.2 weeks on average. The most frequent complication was infection (four cases), controlled by means of débridement, cleansing and antibiotics. A comparative analysis of the immediate and final radiographs of the graft showed an average 30% loss of bone mass despite integration. We conclude that the technique of bone block grafting to correct diaphyseal defects of the radius or ulna is relatively easy to carry out and has a high success rate.
