Subcapital fractures of the fourth and fifth metacarpals treated without splinting and reposition.

The aim of the study was to evaluate the results after treating subcapital fractures in the fourth and fifth metacarpals with immediate mobilisation and without splinting or reduction. We undertook a prospective clinical evaluation of 36 subcapital fractures of the fourth and fifth metacarpals treated with immediate mobilisation and without splinting or reduction during the period 1 January 1990 to 31 December 1992 in the accident and emergency department, Holstebro Central Hospital. After 4 weeks only 4 patients (11%) had restricted movement in the metacarpophalangeal joint (less than 0-80 degrees of movement). The fracture had healed in 33 patients (92%), and 31 of the patients (86%) were completely satisfied. We conclude that subcapital fractures in the fourth and fifth metacarpals can be treated without immobilisation or reposition.
