Randomized Controlled TrialWhich is more effective in adolescent idiopathic scoliosis surgery: batroxobin, tranexamic acid or a combination?
Adolescent idiopathic scoliosis surgery is often associated with significant blood loss and blood transfusion. In this clinical trial, the authors investigated the efficacy of reducing blood loss and allogeneic blood transfusion by using batroxobin, tranexamic acid (TXA) and the combination of the two agents. ⋯ In our study, batroxobin and TXA can markedly reduce the blood loss and the transfusion requirements equivalently. However, TXA performs better in minimizing FFP and the overall drainage than batroxobin. The combination seems to achieve best results and was more effective than either of the two drugs alone. No apparent adverse events were detected in these groups.

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.

Comparative StudyComparison between conservative and surgical treatment in Perthes disease.
The purpose of this study was to compare the results of conservative and surgical treatment in a homogeneous group constituted by patients between 6 and 8 years of age at onset of the Perthes disease with Herring B involvement. ⋯ Non-surgical treatment with a brace is a reliable alternative to surgical treatment in Perthes disease between 6 and 8 years of age at onset with Herring B involvement. However, we could not know whether the good results were influenced by the brace or stemmed from having good prognosis of these patients.

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.

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.
