Hip fracture and upper extremity fracture are most important age-related fracture. However, there have been few reports about the analysis of prevalence or risk factors with concomitant hip and upper extremity fractures. This study aimed to describe the prevalence and clinical implications of the concomitant hip and upper extremity fractures in elderly. ⋯ We found a 3.4% prevalence of concomitant hip and upper extremity fractures. It was found that the younger the age with preserved cognitive ability in elderly patients with a hip fracture, the higher the prevalence of upper extremity fracture. In addition, it is important to keep in mind that patients with a concomitant fracture have a longer hospital stay and difficulty in rehabilitation.

This study was conducted to investigate the stress around nails and cortical bones in subtrochanteric (ST) fractures fixed using short cephalomedullary nails (CMNs) in finite element models (FEMs) and to determine the appropriate short CMN type for different fracture levels. ⋯ Short CMNs 170 or 200 mm in length with 1 distal screw may be used in a limited manner in high ST transverse fractures under the assumptions of anatomical reduction and fracture gap ≤ 1 mm. Meanwhile, short CMN 200 mm in length with 2 distal screws may be an available treatment option in most of ST transverse fractures regardless of the fracture level under the same set of assumptions.

Externally magnetic-controlled intramedullary telescopic nails for bone lengthening have recently gained popularity due to many advantages when compared to more traditional lengthening methods. Patients requiring lengthening often present with a clinical history of previous multiple surgeries increasing the risk for complications of further procedures. However, studies regarding the treatment of complications following implantation of these devices remain scarce in literature. ⋯ The median interval between index and revision surgery was 11.5 months (range 2-15 months). Satisfying clinical results, the intended extend of lengthening and bony consolidation was observed in all 6 patients. We conclude that revision surgery using an intramedullary locking nail with autologous bone grafting after failed telescopic nail-based lengthening represents an useful salvage procedure in these cases.
