We have reviewed the long-term results of 22 patients (23 fusions) with fractures of the os calcis, who had subtalar arthrodesis with correction of the deformity between 1975 and 1991. The mean follow-up was nine years (5 to 20).

All patients were evaluated according to a modified foot score. A radiological assessment was used in which linear and angular variables were measured including the fibulocalcaneal abutment, the height of the heel and fat pad, the angle of the arch and the lateral talocalcaneal and the lateral talar declination angles.

The technique used restores the normal relationship between the hindfoot and midfoot and corrects the height of the heel. This leads to better biomechanical balance of the neighbouring joints and gives a favourable clinical outcome.

The modified foot score showed a good or excellent result in 51% of the feet. Residual complaints were mostly due to problems with the soft tissues. Subjectively, an excellent or good score was achieved in 78% of the cases.

After statistical analysis, except for the height of the heel and the degenerative changes in the calcaneocuboid joint, no significant difference was found in the measured variables between the operated and the contralateral side.

We have assessed the value of using a simple apparatus, the Carpal Box, in patients with suspected scaphoid fracture, to produce elongated and magnified radiographs of the carpus. The interobserver agreement between 60 observers of standard scaphoid radiographs and longitudinal and transverse Carpal Box radiographs (X-CB) was compared in 11 patients. Three-phase bone scanning was used as a comparative standard. If at least 75% of the observers agreed and the result was confirmed by three-phase bone scanning, the outcome was termed reliable.

Scaphoid radiographs and the longitudinal X-CB films were reliable in four patients and the transverse X-CB films in six patients. The bone scan suggested a scaphoid fracture in five of the 11 patients.

Agreement in the interpretation of the standard scaphoid radiographs was acceptable in only 36% of patients: in interpretation of transverse Carpal Box radiographs this figure increased to 55%.
