Abstract

Aim: To compare the outcomes of dynamic compression plating versus interlocking nail procedure in patients presented with fracture shaft of humerus.

Study Design: Randomized control trial

Place and Duration of Study: The study was in Orthopaedic & Spine Unit Hayatabad Medical Complex Hospital Peshawar a for period of 2 years from 1stJuly 2018 to 30thJune 2020.

Methodology: 60 patients of both genders with ages 18 to 65 years presented with fracture shaft of humerus were included in this study. All the patients were equally divided in to two groups. Each group consist of 30 patients. Group A patients were treated with dynamic compression plating while group B received interlocking nail procedure. Pre and post-operative radiographical assessments were done. Post-operative complications were noted at 7th postoperative day. Functional outcomes were examined by the DASH criteria. Data was analyzed by SPSS 24.0

Results: No significant difference was observed regarding age, sex, BMI between both groups. RTA was the most common mode of injury in 40 (66.67%) patients (Group A 21, Group B 19). Most of the fractures were on left side 38 (63.33%). Transverse fracture was the most common type found in 39 (65%) patients (Group A 19, group B 20). Mean union time in group A was significantly shorter than group B 2.46±0.89 months Vs 3.25±1.37 months. In group A delayed union was found in 2 (6.67%) while in group B it was found in 4 (13.33%) patients. At final follow-up in group A, 24 (80%) patients shows excellent, 4 (13.33%) patients shows good and 2 (6.67%) had fair with no poor results while in group B 10 (33.33%) patients shows excellent, 15 (50%) patients shows good 3 (10%) shows fair and 2 (6.67%) patients had poor functional outcomes. A significant difference was found between both groups regarding functional outcomes with p-value <0.05.

Conclusion: Dynamic compression plating shows better functional outcomes with fewer rate of complications and shorter time to bone union as compared to interlocking nail procedure.
