Clavicular hook plate for lateral end fractures:- a prospective study

Abstract

Aim: A prospective study was undertaken over a period of 4 years to evaluate the clinical and radiological outcomes following fixation with a clavicular hook plate for Neer types II and III fractures of lateral end clavicle.

Materials: Thirty-one patients (M:F; 24:7) with a mean age of 49 years (range 25-86 years) were recruited for the study. The mean follow-up duration was 40 months (range 18-68 months). Twenty-three patients were treated primarily and eight patients were treated for symptomatic delayed union.

Results: All the patients achieved clinical and radiological union over a mean of 12 weeks (range 6-18 weeks). Mean constant score at and after 3 months was 94 (range 82-100). Mean ASES score at and after 3 months was 26 out of a maximum of 30.

Conclusion: The clinical result of fracture fixation of lateral end clavicle using hook plate appeared good in terms of fracture union and function. The principal advantages of this method were anatomical reduction of the fracture and early rehabilitation which lead to good shoulder girdle function.
