The induced membranes have osteogenesis-improving capabilities. These capabilities, however, appear to decrease over time. We speculate that the optimal time for performing second-stage surgery may be within a month after implantation of foreign material.

Clavicle hook-plate fixation of unstable lateral clavicle fractures results in a good union rate and good shoulder function.

Interobserver agreement for the hook test and the clinical stress test was excellent, but the sensitivity of these tests was insufficient to adequately detect instability of the syndesmosis intraoperatively.

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.
