Correcting a malunited distal radial fracture usually requires osteosynthetic material applied on the dorsal side of the radius. However, contact of the material with the extensor tendons often produces irritation and rupture problems. The aim of this study is to evaluate the effectiveness of the specific osteosynthetic material (Trimed) in treating malunion of intra- or extra-articular fractures of the distal radius, after a corrective osteotomy.

We examined 11 patients (7 females, 4 males), with average age of 42 years (ranging from 21 to 69 years old), 10 of which presented with symptomatic malunited distal radial fracture of a mean duration of 2.85 months (2–7 months). In one patient the malunited fracture was 30 years old. In 7 patients the malunited fracture was extra articular whereas in 4 patients it was intra articular. A corrective osteotomy was performed in all cases, followed by application of the special osteo-synthetic material by Trimed on the dorsal side of the radius. In seven patients iliac crest bone graft was used, whereas in four allografts were applied. Furthermore, five patients had to undergo additional surgical procedures. More specifically, shortening osteotomy of the ulna in 3 patients, radio-scapho-lunate fusion in 1 and excision of scaphoid with carpal tenodesis in 1 patient.

After a mean follow-up of 15 months (6–27 months) the results were evaluated based on (Fernadez 2001), pain, range of motion, and grip strength. Excellent results (18–20 points) were observed in three patients, good results (15–17 points) in five patients and fair results (12–14 points) in two patients.

We conclude that the use of this particular material provides satisfactory stability on the corrective osteotomy and because of its low profile it can be applied on the dorsal side on the radius without interfering with the extensor tendons.
