title: Percutaneous fixation of displaced proximal humeral fractures: indications based on the correlation between clinical and radiographic results.
abstract: We evaluated 74 patients with displaced proximal humeral fractures (mean age, 70.9 years) treated with closed reduction and percutaneous pinning. Fractures were classified radiographically following Neer's system, and the quality of reduction was assessed according to Kristiansen and Kofoed. Patients were also evaluated clinically with the Constant scale. Overall, the reduction was good in 72% of fractures, but the probability of obtaining a satisfactory reduction of displaced tuberosities was significantly lower in comparison to the humeral head. Four-part fractures obtained the worst radiographic results. The mean Constant scores were 65.8 +/- 18 points for the injured shoulder and 79.5 +/- 9.1 points for the opposite shoulder. Clinical results correlated with the quality of reduction. Closed reduction and percutaneous pinning should be reserved for 2-part fractures, but the technique can also be used in 3-part fractures in elderly patients, in whom an incomplete reduction can yield satisfactory clinical results.
