[Comparison among three cannulated screws and dynamic hip screw combined with antirotation screw for comminut- ed fractures of femoral neck].

Objective: To compare the effect of three cannulated screws and dynamic hip screw (DHS) combined with antirotation screw in treating patients with comminuted fractures of femoral neck.

Methods: From January 2008 to December 2012,67 patients with comminuted fractures of femoral neck were treated with three cannulated screws or DHS combined with antirotation screw. Among them, 36 patients were treated with DHS combined with antirotation screw including 24 males and 12 females with an average of 43.

[The evaluation of posterior ligament complex injury as well as the analysis of its effects in thoracic-lumbar fractures].

Objectives: To evaluate and analyze the role of posterior ligament complex (PLC) in determining therapeutic principle for traumatic thoracic-lumbar fracture.

Methods: From August 2005 to May 2008, 60 patients (38 male, 22 female) who suffered from the traumatic thoracic-lumbar fracture were carried out posterior operations. According to the Magerl traumatic thoracic-lumbar fracture classification system, these cases were classified to subtype A, B and C.
