Abstract

|
Purpose: Authors compare clinical and radiological results of internal fixation group and hemiarthroplasty group for comminuted proximal humerus fracture to find out which the treatment method have to be chose for comminuted proximal humerus fractures.
Materials and Methods : Patients who were treated from March 2005 to March 2007 and available for 2 years follow-up were targets of this study. The internal fixation group had 38 cases, and hemiarthroplasty group included 26 cases. The results were analyzed both clinically and radiologically.
Results: On average, Bone union took 15.6 weeks in the internal fixation group. Constant score between the internal fixation and hemiarthroplasty groups were on average 75±6.5 points and 70±7.4 points (p=0.034). In 3-part fracture, Constant score between both groups were 78±5.4 points from the former and 71±2 points, respectively (p=0.028). In 4-part fracture group, Constant score were 72±8 points for the internal fixation group and 69±9.2 points for the hemiarthroplasty group (p=0.041).
Conclusion: Internal plate fixation can gain better outcome than hemiarthroplasty in 4-part fracture as well as 3-part fracture of proximal humerus by careful dissection for preservation of blood supply for humeral head and optimal reduction.
