Functional and radiological outcomes of mid-shaft clavicle fracture managed by flexible intramedullary nailing
Keywords:Clavicle fractures, Internal fixation, Flexible intramedullary nailing, Functional outcomes of clavicle nail
Background: Clavicle fracture is a common injury accounting for 2.6-5% of all injuries. The commonest site of fracture is the midshaft. Historically clavicle fractures were managed conservatively with figure-of-eight bandage resulting in higher non-union and symptomatic malunion rates. With the advent of operative fixation of these fractures the ideal surgical technique remains elusive. Flexible intramedullary nailing stands out as a minimally invasive and effective method with excellent outcomes for fixation of these fractures.
Methods: A prospective study was carried out over 18 months. A total of 26 patients met the inclusion criteria and were operated with flexible intramedullary nailing. Regular follow up was done till 14 weeks. At each postoperative visit patients were evaluated for shoulder function using constant score and DASH score. Radiographs were taken at each visit to evaluate for fracture alignment and union.
Results: In this prospective study a total of 26 patients with closed midshaft clavicle fracture were managed using flexible intramedullary nail. Average time to radiological union was 7.5 weeks. Average disabilities of arm, shoulder and hand (DASH) score at 14 weeks was 13 and average constant score was 95 suggesting excellent functional outcome.
Conclusions: Flexible intramedullary nailing is a simple, minimally invasive surgical technique with excellent functional outcomes for management of midshaft clavicle fractures.
