Fractures of the neck of the humerus: a review of the late results.

Eighty patients with fractures of the proximal part of the humerus were reviewed not less than 18 months later. The severity of the fracture, the duration of initial rest in a sling and the duration of physiotherapy all independently affected the result. A total of 81 per cent had satisfactory results. The patients with undisplaced fractures had better results (94 per cent satisfactory), but spent longer before beginning physiotherapy which necessitated a longer course. Early active movements within the limits of pain and discomfort are suggested in order to improve the ultimate result.
