Comparative Study between the Precontoured Anatomical Locking Plate and Clavicle Brace for Displaced Mid-Shaft Clavicle Fractures
Background: Most of the midshaft clavicle fractures heal conservatively without further complications with union rate of 94 to 99.7%. Several recent studies recommend surgery for displaced midshaft fracture, to reduce risk of non-union malunion and clavicle shortening. So there is still dilemma for the optimal treatment for displaced midshaft clavicle fracture.
Methods: This was the prospective comparative study performed in Civil Service Hospital, Nepal. Patients were divided into the two groups each containing 40 patients and were treated with figure of eight brace for group 1while group 2 patients were treated surgically.
Results: Mean time to unite the fracture was 11.87±1.78 versus 11.55±1.46 weeks (P value 0.37). There were 14 (35%) cases of malunion more than 10 degree in group 1 and 1 (2.5%) malunion in group 2 (P value 0.001). Twenty nine (72.5%) patients in group 1 and 35 (87.5%) in group 2 were fully satisfied one year after treatment Constant and Murley score in group 1 were 75.22±2.85, 90.87±3.39 and 96.30±1.80 at the time of fracture union, six month and one year after surgery while that score in group 2 were 81.67±2.86, 93.87±2.17, 98.20±1.20 respectively ( P value <0.001).
Conclusions: There is higher incidence of nonunion, symptomatic malunion and inferior perception of satisfaction in conservatively treated patients. Functional outcomes are comparable one year after surgery, however it is significantly better in operative group before that.
