title: Functional comparison of the dynamic hip screw and the Gamma locking nail in trochanteric hip fractures: a matched-pair study of 268 patients.
abstract: The aim of this prospective matched-pair (age, sex, fracture type, residential status, and walking ability at fracture) study was to analyse the short-term outcome after Gamma nail (GN) and dynamic hip screw (DHS) fixation, focusing especially on functional aspects (Standardised Audit of Hip Fractures in Europe [SAHFE] hip fracture follow-up forms), reoperations, and mortality. Both groups consisted of 134 patients. DHS and GN groups did not differ significantly with respect to location of residence at 4 months or returning to the prefracture dwelling (78% vs. 73%, P = 0.224). The change in walking ability at 4 months compared to prefracture situation was better in the DHS group (p = 0.042), although there was no difference in the change of use of walking aids. The frequency of reoperations during the first year was somewhat lower in the DHS group (8.2% vs. 12.7%, p = 0.318). Mortality was lower in the DHS group both at 4 months (6.0% vs. 13.4%, p = 0.061) and 12 months (14.9% vs. 23.9%, p = 0.044). Although walking ability was better and mortality lower in the DHS group, both methods are useful in the treatment of trochanteric femoral fractures.
