[Arthroscopic treatment of tibial intercondylar ridge avulsion fracture with double-root line double tunnel fixation technique].

Objective: To discuss arthroscopic technique of double-root line double tunnel fixation for tibial intercondylar ridge avulsion fracture and its short-term followvup observational results.

Methods: From May 2012 to June 2017, 21 cases of tibial intercondylar ridge avulsion fractures were treated with arthroscope double line double tunnel. Among the patients, 16 males and 5 females were ranging in age from 17 to 45 years old, with an average of 29.

[Therapeutic effects of titanium elastic nails for the treatment of clavicular fractures in elder children].

Objective: To research the application and clinical effect of titanium elastic nails (TEN) for the treatment of closed clavicular fracture in elder children.

Methods: From October 2010 to December 2012,16 elderly children with clavicular fracture of elder children were treated with internal fixation, including 9 boys and 7 girls with an average age of 14.2 yeats old ranging from 9 to 17 years.

[Internal fixation for the treatment of anteromedial facet fracture of the coronoid process of ulna].

Objective: To investigate the effect of operative treatment for anteromedial facet fracture of the coronoid process of ulna,and to study its surgical exposures and fixation techniques.

Methods: From March 2005 to March 2010,18 patients with anteromedial facet fracture of the coronoid process of ulna were treated with open reduction and internal fixation. There were 12 males and 6 females with an average age of 37.

[Clinical application of the combination of postural reduction and kyphoplasty for traumatic thoracolumbar spine fractures].

Objective: To determine the efficacy and feasibility of the combination of postural reduction and percutaneous kyphoplasty for traumatic thoracolumbar spine fractures.

Methods: Thirty-seven patients with single level traumatic thoracolumbar spine fractures were included in this study. There are 28 males and 9 females, with an average age of 48 years (range 24 to 79 years).

[Treatment of chronic osteomyelitis with antibiotic-loaded calcium phosphate cement].

The antibiotic delayed release system which has the characteristics of high local antibiotic concentration,few adverse effects, slow release and long duration, has became one of important methods of treating chronic osteomyelitis. Because of its double action as drug carrier and bone repair material which can induce bone growth and degrade synchronously, drug impregnated calcium phosphate cement (diCPC) is an ideal and safe antibiotic slow release carrier. After clearing focus thoroughly, defect implant with diCPC is an effective method, which has the virtues of convenient operation, good effects and short staying time etc.
