Low energy pelvic ring fractures in the elderly have traditionally been treated conservatively, a treatment with potential long-term complications and loss of self-independence. Percutaneous screw stabilisation of the posterior pelvic ring is a new treatment modality that enables immediate mobilisation. The aim of this study was to assess the functional outcome after sacroiliac stabilisation in the elderly. ⋯ CT guided stabilisation of the posterior pelvis is safe and most patients resumed good function and independent living. The risk of a revision operation was 20%, but trans-sacral screw stabilisation in both S1 and S2 could reduce the risk of implant loosening.

Loading stress due to individual variations in femoral morphology is thought to be strongly associated with the pathogenesis of atypical femoral fracture (AFF). In Japan, studies on AFF regarding pathogenesis in the mid-shaft are well-documented and a key factor in the injury is thought to be femoral shaft bowing deformity. Thus, we developed a CT-based finite element analysis (CT/FEA) model to assess distribution of loading stress in the femoral shaft. ⋯ CT/FEA demonstrated that tensile stress by loading stress can cause AFF. The location of AFF injury could be determined by individual stress distribution influenced by femoral bowing and neck-shaft angle.

Prospective studies on patient related outcome in patients <70years with a femoral neck fracture (FNF) are few. We aimed to investigate functional outcome and health-related quality of life (HRQoL) in 20-69years old patients with a FNF treated with internal fixation. ⋯ Two thirds of the patients with displaced femoral neck fracture healed after one operation and three quarters reported good or excellent functional outcome at 24 months. However, they did not regain their pre-fracture level of HRQoL.

Synthetic bone grafts (SBGs) are widely used to fill bone defects after fracture reduction. This study assessed the long-term resorption of two different calcium phosphate products (A=ChronOS™ inject and B=Norian® SRS®; both DePuy Synthes, Oberdorf, Switzerland) used in the surgical treatment of tibial plateau fractures. ⋯ Case series, Level IV.

The purpose of this study was to investigate whether surgical delay or the educational level of surgeon is associated with early mortality in patients with distal femoral fractures. ⋯ No association between surgical delay or educational level of surgeon and mortality was found. These findings do not support the development of guidelines for decreasing surgical delay in this population.
