Hip fractures are one of the most common types of orthopaedic injury with high rates of morbidity. Currently, no study has compared risk factors and adverse events following the different types of hip fracture surgeries. The purpose of this paper is to investigate the major and minor adverse events and risk factors for complication development associated with five common surgeries for the treatment of hip fractures using the NSQIP database. ⋯ Hip fractures are associated with significantly high numbers of adverse events. The type of surgery affects the type of complications developed and also has an effect on what risk factors significantly predict the development of a complication. Concerted efforts from orthopaedists should be made to identify higher risk patients and prevent the most common adverse events that occur postoperatively.

This study aims to quantify the effect of intra-medullary reaming on rotational displacement of both long diaphyseal segmental tibial fractures (Melis Type III) and short (Melis Type IV) in a cadaveric model with differing degrees of soft tissue stripping. Eighteen fresh-frozen cadaveric specimens (9 matched pairs), median age at death was 85 years (68-92) were used to perform a standardized reaming procedure for an intra-medullary tibial nail and the rotational displacement of the segmental fracture fragment (long and short diaphyseal fractures) was recorded. Rotational displacement was recorded using a goniometer and K-wires positioned in the proximal, segmental and distal fracture fragments. ⋯ Reaming is a major risk factor for rotational displacement of segmental tibial fractures irrespective of the degree of soft tissue stripping. Long diaphyseal segmental fractures rotate more than shorter segmental fractures. We recommend always clamping the fracture during reaming to avoid rotational displacement.

The aim of this study was to determine patient variables that are independent predictors of validated functional outcome scores after humeral diaphyseal fractures. ⋯ Patient age, history of psychiatric illness, insurance type, fracture location and Charlson comorbidity index scores had a statistically significant effect on patient-reported functional outcomes following treatment of humeral shaft fractures, regardless of treatment modality, injury mechanism and associated fractures. The impact of these variables may be age dependent.

The purpose of this study was to assess whether the adhesive permits the collateral repair of axons originating from a vagus nerve to the interior of a sural nerve graft, and whether low-level laser therapy (LLLT) assists in the regeneration process. ⋯ The present study demonstrated that the fibrin glue makes axonal regeneration feasible and is an efficient method to recover injured peripheral nerves, and the use of low-level laser therapy enhances nerve regeneration.
