Closed reduction and percutaneous pinning in proximal humerus fratures-assessment of results using constant-murley shoulder scoring scale

ABSTRACT

The aim of the study was to assess the results of closed reduction and percutaneous pinning in proximalhumerus fracture using Constant-Murley shoulder outcome scoring scale. Experimental study. This study was conducted at KMSMC/AIMH and National Bones and JointsHospital Sialkot from July 20 1 3 to Dec 20 1 4. 20 patients having proximal humerus fractures were operated and closedreduction and percutaneous pin fixation was done. Out of 20 patients,1 1 patients [55%] were male and 9female [45%]. Right side was involved in 14 patients [70%] and left side in 6 patties [30%]. Age rangedb/w 30-50 years with an average age of 38.4 years. Mechanismsof injury were RTA in 10patients [50%], fall from height 6 patients [30%], fall while walking/stair climbing 4 patients [20%]. Thefollow up ranged from 6-18 months with an average follow up of 9 months. The patients were assessed postoperatively at the end of follow up using Constant-Murleyshoulder outcome scoring scale.12 patients [60%] had excellent, 5patients [25%] good, 2 patients [10%] fair and 1 patient [5%] had poor result. The mean Constant-Murley score at the end of follow upwas 88.2 points. The complications observed were; pin track infection 3 patients [15%], loosening of pin2 patients [10%], mild fracture displacement 1 patient [5%] and shoulder stiffness 2 patients [10%],Whereas, deep wound infection, avascular necrosis, hetrotophic ossification and neurovascular injurywere not seen in this study. All the fractures unite satisfactorily b/w 8-14 weeks with an average of 10weeks postoperatively. Closed reduction and percutaneous pin fixation in displaced fractures of proximal humerusis safe and effective procedure with negligible complications and should be adopted as the first line oftreatment if facilities are available
