Background: The AO unreamed tibial nail (UTN) has been used for both open and closed tibial fractures. The reported results have been mixed. We evaluated its outcome in our unit., Aim: To assess the outcome of tibial shaft fractures treated with the AO UTN., Methods: Forty-eight patients underwent intramedullary nailing between 1995 and 2000 using the AO UTN. Follow-up details were available for 45 patients., Results: Forty-four fractures united (97%). Complications included one non-union (2.2%), 15 delayed unions (33%), nine had either broken or bent interlocking screws (20%), six malunions (13%) and three patients underwent fasciotomy for compartment syndrome (7%). Twenty-one patients underwent at least one additional operation to obtain union (47%). Of these, five underwent exchange nailing (11%)., Conclusions: The AO UTN does have a high complication rate and, should it be used, we feel that early dynamisation or exchange nailing be considered to hasten union and prevent screw breakage.

Articular cartilage defects of the knee are a common condition diagnosed at arthroscopy. The management of these osteochondral lesions is controversial. We present our experience using carbon fibre implants to repair these defects in 18 patients. Eleven patients (61 per cent) had an osteochondral defect of the medial femoral condyle. Two patients had isolated patellar defects. The mean knee assessment and functional scores were 75 and 80 respectively using The Knee Society Clinical Rating System. Serial post-operative M.R.I. scanning revealed that there was no loss of implant position with an extensive local tissue response and good joint congruity. Overall, 11 patients (61 per cent) returned to their normal sporting activity, while 3 patients (18 per cent) had a poor result. One of these underwent a patellectomy. We conclude that carbon fibre implants may have a role to play in the management of osteochondral defects of the femoral condyles.

Sixteen polytraumatized patients with a variety of unstable pelvic ring fractures were treated with operative fixation. We have found that an aggressive approach with adequate early stabilization of the pelvis offers many advantages over conservative management particularly in polytraumatized patients.

Thirty-seven tibial shaft fractures in 34 patients were treated with the Grosse-Kempf interlocking intramedullary nail over a two year period. Thirty-six tibiae were consolidated at a median of 17 weeks; one had re-fractured following nail removal in a separate injury, but was now uniting on conservative treatment. Using very detailed clinical and radiological analysis, and excluding the patient who had re-fractured, the results were excellent in 19, good in 8, fair in 6 and poor in 3. The most significant complications were haematoma formation and additional comminution during nail insertion. Overall, we found tibial nailing to be a satisfactory procedure, facilitating rapid rehabilitation with early weight bearing and resulting in predictable fracture healing in good alignment.
