Treatment for Distal Radius Fracture Using External Fixation with Electrical Stimulation

We performed treatment for distal radius fracture using the Bone Grow External Fixator (BGF, MES co.) which combines non-bridging type external fixation with electrical stimulation. 7 fractures (three males and four females) were treated with the BGF. The age ranged from 32 to 76 years (average; 59.3 years). We removed the BGF four to six weeks after recognizing bone union on X-ray.As the BGF is of the non-bridging type, it allows range of motion exercise at an early stage and prevents loss of radius length after removal. However this method by itself is not adequate for severe osteoporotic cases and comminuted fractures. For these cases we obtained satisfactory results by using with β-TCP, minimum open reduction and internal fixation. We need more cases to evaluate utility of electrical stimulation.

Clinical Result of Treatment for Femoral Shaft Fracture Using Interlocking Nail System

We have treated femoral shaft fractures using the interlocking intramedullary nailing system since 1992. We investigated factors contributing to radiological results in 70 femora of 66 patients with femoral shaft fracture. As a result, 68 femora of 64 patients eventually achieved bone union in an average of 245 days (23 to 1029 days) after the first surgery. Eight femora of eight cases reguired reoperation. Static locking, age, and the degree of comminution were significantly correlated with radiological results, as were age and degree of comminution were significantly correlated.
