The Outcome Analysis Of That Humeral Shaft Fracture Is Used Double Plates Fixation Through Anterolateral Approach

Objective:To analyze the clinical outcome of anterolateral extended approach to perform the open reduction and internal fixation of humeral shaft fractures.Methods:during September 2012 to September 2014,116 humeral shaft fracture cases were treated using anterolateral extended approach in Yan Bian University Hospital. The study met the inclusion criteria of humeral shaft fracture 71 cases, using randomly divided 34 patients given a single plate, double plate group 37 cases. Aged 18-82 years, mean age 44.62 years.39 males and 32 females; 37 cases on the right side, left side of the 34 cases; 32 cases of direct damage, indirect damage 39 cases. Follow-up of 12-24 months, with an average 15.51months. Compared postoperative fracture healing, shoulder function, iatrogenic radial nerve injury, infection rate between two groups.Results:36 cases of double steel group achieve fracture healing standard,, one case of delayed fracture healing by releasing unfavorable factors, six months after fracture healing, a healing fracture was 97.29%. single plate group,28 patients achieved fracture healing standards, a healing fracture was 82.35%. Three cases of delayed union, nonunion three cases, including two cases of fixation failure, loose screws, one case of plate deformation of the six cases does not meet the standard of fracture healing in patients with secondary parallel double plate fixation surgery, postoperative six months are up fracture healing. Healing rates between the two-plate group and single-plate group had statistically significant difference (p<0.05). Shoulder joint function score, double steel group,23 cases rated excellent,11 cases rated good, good rate of 91.89%; single plate group rated excellent in 17 cases,8 were rated good, excellent shoulder was 73.53%. Excellent shoulder joint function score between the rate of double and single steel plate group group had statistically significant (p<0.05).Elbow function score, double steel group,21 cases rated excellent,14 cases rated good, good rate of 94.59%; single plate group rated excellent in 18cases,7 were rated good, excellent elbow was 73.53%. Excellent elbow function scores between the rate of double and single steel plate group group had statistically significant (p<0.05).There was no iatrogenic radial nerve injury and infection in two groups.Conclusions:1.anterolateral extended approach is a safe and reliable approach to treat the humeral shaft fracture.2.The healing rate of dual plate fixation is higher than a single plate fixation in elbow and shoulder fracture.
