Restoration and reconstruction of the knee stability for floating knee injury / 中华创伤杂志

Objective To investigate the methods and therapeutic effects in reconstructing and restoring the knee stability of floating knee injury. Methods A total of 38 patients with floating knee injury combined with acute knee instability treated from January 2000 to January 2006 were retrospectively studied to evaluate the efficacy of different procedures. Results All patients were followed up for 1-4 years (mean 1.5 years), which showed fracture healing in all patients. There occurred postoperative wound infection in three, internal fixator loosening in two, anterior cruciate ligament laxity in one and osteearthritis in two. According to Score of Hospital for Special Surgery (HSS) for knee function,the knee function was excellent in 32 patients, good in five and fair in one, with excellence rate of 84%. Conclnsions During the treatment of floating knee injury, attention should not only be paid to the reconstruction of the bone continaity, but also to the restoration of ligaments, meniscus, joint capsule and muscles.

[Objective]To analyze the character of the complex proximal humeral fracture,study their operative methods and evluate the efficiency of treatment for complex proximal humeral fracture in elder patients with LCP plate.[Method]From(Oct 2004 to June 2006,16 elder patients with complex proximal humeral fracture were admitted and treated with open reduction and LCP plate internal fixation,regular clinical follow-up was executed by our medical team,the postoperative results were observed and the efficiency were evaluated by us.[Result]Sixteen cases obtained postoperative clinical results from 6 to 18 months(average 12.3 months),the fracture were healed in all cases,the shoulder function were evaluated with Neer shoulder functoin scoring systerm,the execellent result were 11,good 2,normal 2 and poor 1,the execellent and good results were 81.3% in all cases,6 cases got anatomic reduction,6 cases got nearly anatomic reduction,3 normal and 1 poor which were certified by radiographic examination.[Conclusion]The treatment for complex proximal humeral fracture in elder with LCP plate has less invasive,firm internal fixation and satisfactory shoulder function recovery.It is a very satisfactory internal fixtion for complex proximal humeral fracture in elder patients.

The long term result of the acute closed rupture of achilles tendon treated by the short incision and tenocutaneous relaxing suture / 中国矫形外科杂志

[Objective]To evaluate the long term effect of the short incision and tenocutaneous relaxing suture to treat the acute closed rupture of the Achilles tendon.[Method]28 cases were treated by short incision and tenocutaneous relaxing suture from 1996-2005,The scar tissue and blood blocks between the ends of ruptured Achilles tendon were first debrided completely,then treated with percutanneous decmpression suture,the duration of follow up ranged from 2 years to 10 years.The treatment outcome were evaluated by Arner-Lindholm evaluation system and the MRI of post operation.2 cases were lost.[Result]According to the Arner-Lindholm evaluation system and the MRI of post operation,the treatment outcome were excellent in 18,and good in 6,with excellent rate of 92%,No complication including nerve injury and infection were found after operation,except 1 rerupture of Achilles tendon was found during the follow up period.The MRI showed the rupture Achilles tendon were repaired and remodeled very well in all cases.[Conclusion]The short incision and tenocutaneous relaxing suture is an ideal surgical technique,with good Clinical result and less Significant complication.

Short incision and tencutaneous relaxing suture in treating closed rupture of the Achilles tendon / 中华创伤骨科杂志

Bilateral chest navel flaps with nerves for repairing the avulsion injury of total hand skin / 中华创伤骨科杂志

Objective To explore a therapeutic method for repairing the avulsion injury of total hand skin. Methods Bilateral chest navel flaps with nerves were used to repair the avulsion injury of total hand skin. Two nerves of the right lateral flap were anastomosed with the first and third common palmar digital nerves respectively; two nerves of the left lateral flap were anastomosed with the dorsum manus of ulnar nerve and cutaneous branch of radial nerve respectively. Results Postoperative follow up of 12 to 15 months showed that two cases were successful. The injured hands regained thalposis and thigmesthesia; the ulnar hand had sensitive thigmesthesia when touching a table; and the grasping function of the hand recovered partially. Conclusion Bilateral chest navel flaps with nerves are recommendable to all kinds of hospitals for repairing the avulsion injury of total hand skin.
