Repair of avascular meniscal injuries using juvenile meniscal fragments: an in vitro organ culture study.

We investigated whether the implantation of juvenile allograft and minced meniscal fragments could improve the healing of avascular meniscal injuries, which cannot heal spontaneously. Concentric cylindrical explants were excised from the inner two-thirds of swine medial menisci. The inner cylinder consisted of a "sandwich" structure, with minced juvenile meniscal fragments, juvenile meniscal columns, minced mature meniscal fragments, or mature meniscal columns implanted in the middle.

[In vitro meniscal culture of juvenile porcine].

Objective: To observe the histological changes of juvenile porcine menisci in an in vitro organ culture system. It was hoped that the experiment can provide evidence for the study of menisci in an in vitro organ culture model.

Methods: Eight juvenile swines of one month old were involves in the study.

[Treatment of Sanders type III and IV calcaneal fractures with open reduction and internal fixation].

Objective: To investigate the surgical techniques and results of open reduction and internal fixation for the treatment of Sanders type III, IV calcaneal fractures.

Methods: From January 2004 to January 2010, 58 feet of Sanders type III, IV in 51 patients were treated with open reduction and plate fixation through L incision. There were 29 males and 22 females,the age ranged from 17 to 58 years with an average of 29.

[Surgical treatment for Tile C type pelvis fracture through posterior approach].

Objective: To study the clinical results of surgical treatment for Tile C type pelvis fractures with internal fixation by posterior approach.

Methods: From January 2005 to June 2009, 12 patients with Tile C type pelvis fracture were treated by open reduction through posterior approach. There were 8 males and 4 females, with an average age of 39.

[Effectiveness of traumatic dislocation of knee joint combined with multiple ligament injuries treated by stages].

Objective: To observe the effectiveness of traumatic dislocation of the knee joint combined with multiple ligament injuries treated by stages.

Methods: Between june 2005 and November 2008, 13 cases of traumatic dislocation of the knee joint combined with multiple ligament injuries were treated by stages, including 9 males and 4 females with an average age of 30.7 years (range, 18-54 years).
