Multicenter Study
Safety of the modified posteromedial approach in complex ankle fractures: Comparative analysis versus posterolateral access.
The aim of the study was to evaluate the safety of the modified posteromedial approach (MfPM) in the surgical management of complex ankle fractures in terms of local complications. ⋯ The MfPM approach is safe and may become as readily used as the PL due to the low incidence of postoperative local complications, especially in fractures with a large fragment and posteromedial extension in which greater access to the posterior pilon can facilitate instrumentation for anatomic reduction and fixation.

Dynamization of proximal femoral nailing by removal of distal interlocking is one of the recommended treatment options for nonunions of femur fractures. However, in certain inter-/subtrochanteric fractures, gliding of the nail along the femoral shaft is blocked by lateral femoral cortical support of the lag screw. For these cases, Biber et al. proposed lateral cortical notching (LCN), in which the supporting lateral bone is removed. This study investigates the biomechanical effect of LCN on gliding of proximal femoral nailing and stress distribution at the bone/implant interface. ⋯ Lateral cortical notching facilitates gliding of a distally dynamized proximal femoral nail along the femoral shaft axis in intertrochanteric fractures. Additionally, the lack of lateral cortical bone support at the lag screw reduces von Mises stress at the bone/implant interface and thus could lower the risk for implant breakage and peri‑implant fractures.

The optimal time to intramedullary internal fixation for patients with isolated and unilateral femoral shaft fractures was investigated by the American College of Surgeons-Trauma Quality Improvement Program (ACS-TQIP). ⋯ Accelerated intramedullary internal fixation within 13.88 h was associated with a significantly decreased risk of PE compared with standard fixation in patients with isolated and unilateral femoral shaft fractures without additional mortality risks.

Comparative Study Observational Study
Antibiotic cement-coated rigid locked nails in infected femoral and tibial nonunion. Reoperation rates of commercial versus custom-made nails.
The objective of this study is to assess bone union, infection control, and reoperation rates in a series of patients with infected femoral or tibial nonunion treated with antibiotic-cement-coated rigid nails and to compare the results obtained with custom-made nails versus commercial nails. ⋯ III comparative, observational, non-randomized.

Acetabular fractures are devastating injuries that can affect patients of different ages, as well as being associated with high or low energy trauma. Conversion to total hip arthroplasty (THA) results in increased complication rates, resource use and costs compared to primary THA due to osteoarthritis. The aim of this paper is to describe a retrospective cohort of patients over 65 years of age who presented with an acetabular fracture and were treated with open reduction and internal fixation (ORIF). ⋯ The conversion rate reported in our cohort of elderly patients is similar to that reported in the literature in patients of all age ranges. The quality of reduction was a significant factor in predicting progression to conversion to THA.
