Vacuum-assisted closure combined with a closed suction irrigation system for treating postoperative wound infections following posterior spinal internal fixation.

Background: Wound infections after posterior spinal surgery are a troublesome complication; patients are occasionally forced to remove the internal fixation device, which can lead to instability of the spine and injury to the spinal cord. The purpose of this study was to evaluate the efficacy of modified vacuum-assisted closure (VAC) for treating an early postoperative spinal wound infection.

Methods: We conducted a retrospective study of 18 patients with wound infections after posterior spinal surgery from 2014 to 2017 at a single tertiary center.

[Research on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty].

Objective: To study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

Methods: From January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.

[Analysis on morbidity factor of bilateral intertrochanteric fractures].

Objective: To study the morbidity factors of bilateral intertrochanteric fractures by analyzing medical records, so as to provide evidences for preventing the multiple intertrochanteric fractures.

Methods: From Janurary 2000 to June 2009, 68 patients with bilateral intertrochanteric fractures were studied, including 31 males and 37 females, ranging in age from 42 to 95 years with an average age of 75 years. There were type A1 in 24 hips, type A2 in 96 hips, and type B3 in 16 hips.

[Case-control study on therapeutic effects between clavicular hook plate and tension band fixation for the treatment of sternoclavicular joint dislocation].

Objective: To compare therapeutic effects between clavicular hook plate and tension band fixation for the treatment of Allman type II to III sternoclavicular joint dislocations.

Methods: A retrospective survey was analyzed from May 2000 to September 2008. A total of 31 patients with Allman type II to III sternoclavicular joint dislocations were followed up.

[Clinical outcome of minimally invasive internal fixation of pelvic ring injuries with cannulated screws].

Objective: To evaluate the safety and reliability of percutaneous internal fixation for pelvic ring injuries with cannulated screws.

Methods: Forty-eight patients (21 male and 27 female, aged from 17 to 61 years with an average age of 38 years) with unstable pelvic ring injuries were treated with closed reduction and percutaneous cannulated screws fixation under C-arm fluoroscopic guidance. According to Tile's classification, the patients were classified into type B1 in 4 cases, B2.
