Summary. In order to evaluate interobserver and intraobserver agreement of the Frykman and AO classifications and their variations between assessors with different levels of experience, three hand specialists, a fellow and two senior residents classified radiographs of 200 fractures of the distal radius in anteroposterior and lateral views. Reproducibility was assessed by the use of the proportion of agreement and kappa coefficient between pairs of observers. The Frykman classification showed moderate interobserver reproducibility (kappa = 0.43) and good intraobserver reproducibility (kappa = 0.61). The experience of the reviewers did not significantly affect either of these. The AO system showed regular interobserver reproducibility (kappa = 0.37) and moderate intraobserver reproducibility (kappa = 0.57). The younger group obtained higher intraobserver agreement than the senior. Possible causes for the low reproducibility of both classifications are discussed together with a review of the literature. We do not recommend the Frykman or AO classifications for clinical application because of their questionable reproducibility.

We retrospectively evaluated the clinical and radiological outcomes of a consecutive cohort of patients aged > 70 years with a displaced fracture of the olecranon, which was treated non-operatively with early mobilisation. We identified 28 such patients (27 women) with a mean age of 82 years (71 to 91). The elbow was initially immobilised in an above elbow cast in 90° of flexion of the elbow for a mean of five days. The cast was then replaced by a sling. Active mobilisation was encouraged as tolerated. No formal rehabilitation was undertaken. At a mean follow-up of 16 months (12 to 26), the mean ranges of flexion and extension were 140° and 15° respectively. On a visual analogue scale of 1 (no pain) to 10, the mean pain score was 1 (0 to 8). Of the original 28 patients 22 developed nonunion, but no patients required surgical treatment. We conclude that non-operative functional treatment of displaced olecranon fractures in the elderly gives good results and a high rate of satisfaction.
