To introduce the application of homeopathic minimally invasive treatment for the lower extremity fractures, and analyze the tips and successful rate.

From October 2015 to May 2017, 58 patients with lower extremity fractures admitted to the trauma center of Qilu Hospital of Shandong University (Qingdao) were included in this study. There were 38 males and 20 females with an average of (36±12) years. All patients were treated with homeopathic minimally invasive methods with the application of Zhang's bidirectional traction device and followed up regularly. The outcome was evaluated according to successful rate of closed reduction, wound infection, neurovascular complication, fracture union and functional recovery.

53 patients were followed up with a mean duration of (11±4) months (range, 7-24 months). With the aid of Zhang's bidirectional traction device, all patients were obtained satisfactory closed reduction; 21 cases of 31 tibial plateau fractures achieved approximately anatomic reduction, other 15 cases with depressed articular fragments received closed minimally reduction and autograft. One superficial infection occurred and was finally healed with routine dressing changes, no neurovascular injury were found, all fracture healed, no cases showed implant broken or reduction loss. 53 patients obtained satisfactory functional outcome, all expect 1 restored pre-injury activity and work status.

Homeopathic minimally invasive treatment with Zhang's bidirectional traction device is a convenient and effective option for lower extremity fractures. It is simple, rapid, minimally invasive and rapid recovery that worthy of clinical promotion.
