Mismatch of anatomically pre-shaped locking plate on Asian femurs could lead to malalignment in the minimally invasive plating of distal femoral fractures: a cadaveric study.
LCP-DF (locking compression plate-distal femur) has been introduced as an anatomically pre-shaped plate that does not require further contouring. However, the LCP-DF was developed based on skeletal measurements in Caucasians. It is unknown whether the LCP-DF fits Asians. ⋯ A rather consistent pattern of mismatch was found at the proximal part of the 11-hole LCP-DF. An attempt to fit the plate to the bone at this level may cause valgus malalignment at the fracture site.

Short reconstruction nail for intertrochanteric fracture: does it really fit Asian feature?
The Trigen short reconstruction trochanteric antegrade nail (TAN) is considered most suitable for the small skeletons of Asian patients. We have evaluated the results of TAN for intertrochanteric fractures in Asian patients. ⋯ Despite the theoretically better design of TAN and the healing of most fractures and good activity at last follow-up, poor reduction and coxa vara caused by insertion of the nail could not be completely avoided, and the design of the distal part of the nail had the potential to cause femoral shaft fracture. Future improvements are necessary to enable the use of this system in Asians.

Cup positioning in total hip arthoplasty: spatial alignment of the acetabular entry plane.
Correct cup positioning is one of the keys for successful total hip replacement. There are mechanical and computer assistant guides for correct cup positioning in the market. To optimize the cup positioning, the use of navigation systems is recommended. The aim of this study was to compare spatial orientation of the acetabulary entry plane in relation to tables plane which is used by mechanical guides as well as anterior pelvic plane used for cup orientation by navigation systems. ⋯ The use of mechanical alignment guides for cup orientation during total hip arthroplasty based on table's plane in patient's supine position is a successful method to achieve proper cup orientation.

Occult hip and pelvic fractures and accompanying muscle injuries around the hip.
We investigated the incidence of occult hip and pelvic fractures and associated muscle injuries around the hip. ⋯ Occult hip and pelvic fractures were almost equally seen among 113 cases with suspected hip fracture but were negative on plain radiography. Different patterns of associated muscle injuries in cases of occult hip fracture and pelvic fracture suggest that the mechanism of hip fracture and pelvic fracture is possibly different.

Case ReportsFree vascularized metacarpal bone graft combined with extended dorsal metacarpal artery flap for phalangeal bone and soft tissue loss: case report.
A 45-year-old man suffered from a complex bone and soft tissue defect of the middle phalanx of his left middle finger after an electric saw injury. Here, we present the patient's clinical and radiological outcomes after reconstruction with a free vascularized metacarpal II bone graft and an extended distally based second dorsal metacarpal artery skin flap (DMCA). To our knowledge, this is the first description of a free vascularized metacarpal bone graft combined with DMCA for distal finger reconstruction.
