Nail-extraction device mismatch: an issue in developing countries intramedullary nail removal practice.

PURPOSE: Intramedullary nail is the gold standard in the management of long bone diaphyseal fractures of tibia and femur. The jig of these nails has corresponding extraction device whose pitch for nail coupling come in various sizes. This unlike plate and screws may be difficult to predict preoperatively and may pose a problem during removal. Difficulties in removal may arise due to the proliferation of nail brands especially in developing countries. The study aims to identify the incidence of extraction device mismatch among orthopaedic surgeons in Nigeria as well as the indications and complications associated with intramedullary nail removal. METHODS: A two-page questionnaire was administered to 87 orthopaedic surgeons attending the Annual General Meeting of the Nigerian Medical Association. The attitudes of the participants towards intramedullary nail were assessed. RESULTS: All participants agree to asymptomatic removal. Patients wish was the leading indication for asymptomatic removal among the participants. Sixty-one percent of the surgeons have had the need to remove a nail different from the brand in the hospital their practice. The commonest indication for symptomatic removal was infections. Forty-seven percent of the participant encountered nail extraction-device mismatch. CONCLUSIONS: The incidence of extraction device mismatch may portend a public health issue. There may be need for patient who had intra medullary nail insertion to be told their brand. We advocate for standardization of extraction device pitch for intramedullary nail.

Comparative prospective study of early outcomes after osteosynthesis with locked intramedullary nailing or plating for closed femoral shaft fractures at the National Orthopaedic Hospital Enugu, Nigeria.

AIM OF THE STUDY: This was to compare the early outcome of closed femoral shaft fractures treated with locked intramedullary nailing and plating at the National Orthopaedic Hospital Enugu. METHODS: The study was a prospective study over 12-month period at the National Orthopaedic Hospital Enugu. Ethical clearance was obtained from the hospital ethical committee. Written informed consent was obtained from all prospectively recruited participants. Patients who met the inclusion criteria were randomly selected by simple balloting into either intramedullary nailing group or plating group. The patients were evaluated at presentation and postoperatively within 48 hours, then at two weeks, six weeks, 12 weeks and 18 weeks, respectively. Participants were evaluated using Thoresen criteria. RESULTS: A total of 52 femoral shaft fractures in 50 patients were included and analysed using SPSS version 20.0. Bone union was obtained in all the patients in the intramedullary nailing group at 12 weeks and in 84.6% patients in the plating group between 12 and 18 weeks. The overall wound infection rate was 11.5% in the locked intramedullary group and 7.7% in the plating group. Similarly, the overall limb length discrepancy was 11.5% in the locked intramedullary nailing group and 19.2% in the plating group. Based on the Thoresen criteria, good to excellent outcome was achieved in 65.4% of patients in the locked intramedullary nailing group. DISCUSSION: The patients in both groups were evaluated clinically, radiologically and functionally based on the Thoresen criteria and significantly higher number of patients in the intramedullary nailing group (17; 65.4%) than the plating group had good to excellent outcome (x2 = 9.734; p = 0.020). CONCLUSION: The early outcome of treatment of closed femoral shaft fractures in adults is significantly better following locked intramedullary nailing than plating.
