Cephalo-medullary nailing versus dynamic hip screw with trochanteric stabilisation plate for the treatment of unstable per-trochanteric hip fractures: a meta-analysis.
The use of cephalo-medullary nails (CMN) is a widely accepted management option for the treatment of unstable per-trochanteric hip fractures. A growing body of literature has reported good functional and radiological outcomes in patients managed with a dynamic hip screw supplemented with a trochanteric stabilisation plate (DHS w/ TSP). However, a robust meta-analysis does not exist in the current literature comparing the two fixation methods.Management of these kinds of injuries is very challenging in orthopaedic practice, yet no strong evidence is in place to delineate which implant gives the best results. This meta-analysis is the first to determine the efficacy of CMN versus DHS w/ TSP.An up-to-date literature search was performed using a predetermined search strategy and eligibility criteria. All suitable literature was appraised for methodological quality using the Cochrane’s collaboration tool. Hospital stay, operative time, intra-operative complication rate, mechanical failure rate, infection rates, revision rates and functional outcomes were all considered.A total of five studies were included in the meta-analysis. The results of this analysis suggest that CMN is only associated with lower revision rates when compared to DHS w/ TSP; however, no significant difference was found in terms of hospital stay, operative time, blood transfusion, complications rate and functional outcome.Both CMN and DHS w/TSP proved to be reliable in the management of unstable per-trochanteric fractures; however, more extensive datasets are required to draw robust conclusions.
