To invstigate the influence of femoral neck area on larger anteversion angle of lag screw guide pin initial placement in proximal femoral intertrochanteric fracture treated with intramedullary nail. ⋯ The internal rotation of the affected limb and screw guide pin level may affect the anteversion angle of femoral neck when lag screw guide pin initial insertion, cause it to be too large and the screw guide pin level is the main influencing factor.

As one of the most common fractures of the foot, the blood supply characteristics and unique anatomy of proximal fifth metatarsal fracture makes a high risk of delayed union or non-union of fractures occurring at the junction of the diaphyseal-metaphyseal. At present, the classification system of proximal fifth metatarsal fracture is complicated and not yet unified, and Lawrence and Botte classification is more recommended. The system divides proximal fifth metatarsal fracture into three types:avulsion fractures of tuberosity(Zone I), fractures at the metaphysis-diaphysis junction, which extend into the fourth-fifth intermetatarsal facet (Zone II) and the proximal diaphyseal fractures(Zone III). ⋯ There are a variety of surgical methods for proximal fifth metatarsal fracture. For the fracture of Zone II and Zone III, percutaneous intramedullary screw is the first choice. In addition, clinicians should also have a thorough understanding of common complications of fracture and associated disposal methods.

To observe the effect of proximal humerus internal locking system (PHILOS) plate in the treatment of Neer 2 and 3 part fractures of proximal humerus through tuberosity approach. ⋯ The PHILOS plate for the treatment of proximal humerus fractures has the advantages of simple operation, small injury and quick recovery of shoulder joint function.

To explore the clinical effects of bone filling bag vertebroplasty in treating osteoporotic vertebral compression fractures. ⋯ The clinical effect of bone filling bag vertebroplasty in the treatment of osteoporotic vertebral compression fractures is similar to percutaneous kyphoplasty, it can effectively relieve the pain, restore part vertebral body height and obviously reduce the leakage rate, with safer, it is a simple, rapid and effective therapeutic method.

Randomized Controlled Trial
[Clinical observation of ultrasound guided popliteal sciatic nerve combined saphenous nerve block for hallux valgus patients with metatarsophalangeal joint dislocation].
To explore clinical effects of ultrasound guided popliteal sciatic nerve combined saphenous nerve block in patients with anterior foot orthopedics. ⋯ Ultrasound guided popliteal sciatic nerve combined saphenous nerve block could meet demand of hallux valgus patients with metatarsophalangeal joint dislocation. Compared with lumbar anesthesia, it could maintain hemodynamic stability, prolong effective analgesia time after operation, and improve patients' overall comfort and safety for free activity above the knee joint.
