Varus mal-alignment and residual displacement are associated with delayed union in subtrochanteric femur fracture- A retrospective observational study.

Background: Subtrochanteric femoral (ST) fractures are associated with high rates of delayed and non-union. The aim of this study was to analyse the risk factors associated with delayed/non-union in ST fractures.

Methods: All patients with surgical stabilisation of ST fractures during the period 2014 to 2019 were identified in an electronic patient records database in two trauma centres.

Hallux Valgus Interphalangeus Measurement: Comparison of the 2 Radiographic Methods.

Background: To determine the reliability of Delta PP (difference in medial and lateral proximal phalanx wall length) compared with HIA (hallux interphalangeal angle) in the assessment of HVI (hallux valgus interphalangeus) in both preoperative and postoperative radiographs.

Methods: This was a retrospective observational study of 186 feet with hallux valgus. The number of cases required to adequately power the study was 128.
