Bohler's angle: correlation with outcome in displaced intra-articular calcaneal fractures.
Bohler's tuber joint angle is commonly assessed when evaluating calcaneal fractures. A severe heel fracture will result in a significant decrease or loss of this angle. The purpose of this study was to evaluate the correlation between Bohler's angle and functional outcome in displaced intra-articular calcaneal fractures. ⋯ In this study, Bohler's angle had significant prognostic value in terms of predicting morbidity. Fractures with a markedly diminished Bohler's angle demonstrated a much poorer two-year outcome regardless of treatment. It would seem that the initial Bohler's angle was highly prognostic, regardless of treatment modality.

To evaluate the mechanical effects of medial and lateral blocking screws in supplementing intramedullary nail fixation of high proximal and low distal tibial fractures treated with small-diameter intramedullary nails. ⋯ The study suggests that medial and lateral blocking screws can increase the primary stability of distal and proximal metaphyseal fractures after nailing and can be an effective tool for selected cases that exhibit malalignment and/or instability.

This study was designed to examine the effect of pulsatile irrigation on microscopic bone architecture and its time-dependent efficacy in removing adherent slime-producing bacteria from cortical bone. ⋯ In this in vitro study, compared with HPPL, LPPL led to less structural damage and was equally effective in removing bacteria within three hours debridement delay; however, the efficacy of LPPL at six hours debridement delay is questionable. This finding may have clinical significance in the development of infection following open tibial fractures.
