Abstract:
[Objective]To investigate the treatment method and clinical outcome of posterior midline approach and internal fixation with Y-shaped plate for complex distal 2/3 humeral fracture.[Method]From November 2001 to February 2006,33 patients with complex distal 2/3 humeral fracture were treated with posterior midline approach and Y-shaped plate internal fixation.There were 5 females and 28 males,with a mean age of 37.6 years(ranging from 19 to 57 years).According to AO/ASIF classification,type C1 fracture was found in 21 cases,type C2 in 3 cases and type C3 in 9 cases.Seven of these were open fractures(4 cases of Gustilo-Anderson type Ⅰ and 3 cases of type Ⅱ).Measures of auto-ilium transplant(21 cases)and homolegous allograft bone transplant(12 cases)were also taken.The operation was performed at 2.5 hours～7 days after injury with mean 3 days.[Result]Thirty-three patients were followed up for a mean period of 15.6 months(6～28 months).Fractures of 31 patients healed at 19 weeks after the treatment.Delayed union occurred in two patients.The function of the elbow was evaluated according to Morrey's scale,the results showed excellent in 24 cases,good in 7 cases,and poor in 2 cases.At the last follow-up,the muscle strength of elbow extension was about 4～5 grade.[Conclusion]Posterior midline approach and Y-shaped plate internal fixation of complex distal 2/3 of humeral fracture is a safe and effective technique.Protecting the radial nerve and ulnar nerve,prophylactic bone grafting and reasonable postoperative rehabilitation are very important to obtain satisfactory clinical outcome.
