Background:
Aim of our study was to evaluate the use of Locking Compression Plate (LCP) in patients with long standing nonunions of the clavicle with osteoporotic bones.
Material And Methods:
There were a total of 11 patients. Surgery was performed for painful nonunion with shoulder dysfunction. Average time since injury was 6.9 months (3-39 months). Nonunions were stabilized by a 3.5-mm LCP, applied on the antero-inferior surface of the clavicular shaft. A six-hole LCP was used in eight cases. In three patients seven-hole LCP and in one patient eight-hole LCP was used. The fixation was supplemented by autogenous cancellous bone graft (except in hypertrophic nonunions). Patients were followed for a mean of 2.8 (1-3) years.
Results:
The average time of radiologic union was 5.3 months (3-9 months). Union was achieved in all patients. Subjective clinical assessment was performed using the Disabilities of the Arm, Shoulder, and Hand functional score (DASH). The mean DASH score preoperatively was 42 (25-52) and postoperatively was 24 (11-34). Superficial infection and features of reflex sympathetic dystrophy were seen in one patient each.
Conclusion:
Long standing clavicular nonunion with osteopenic bone is a difficult problem to treat. Our study shows that LCPs can be an improved implant option with good fracture healing.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
