We have evaluated the clinical application of the Fernandez classification without questioning the scientific validity, by assessing the interobserver reliability and intraobserver reproducibility. A set of 25 radiographs of distal radius fractures were given to six assessors along with details of Fernandez classification. The assessors classified the fractures on two different occasions 3 months apart. The outcome was assessed using kappa statistics and demonstrated poor interobserver reliability and intraobserver reproducibility. Caution should be exercised when using this classification for clinical practice and research.

Background: The purpose of this study is to test the hypothesis of the new classification system of distal end radius fractures (Barzullah working classification) proposed by one of the author in a prospective cohort study, among the orthopaedic residents. Methods: The initial post-injury radiographs of 300 patients with distal radius fractures in a tertiary centre were classified by two junior residents (JR1 and JR2) and two senior residents (SR1 and SR2) in the emergency department over a period of two years. The collected data was analysed statistically by using Cohan's kappa for measuring Intraobserver reproducibility and Fleiss kappa for measuring Interobserver agreement. Results: The mean kappa value for Interobserver agreement was 0.53 (moderate agreement) at the end of one year and the mean kappa value at the end of study period was 0.64 (substantial agreement). The mean kappa value for Intraobserver reproducibility of JR1 was 0.45 (moderate agreement), JR2 was 0.39 (fair agreement), SR1 was 0.62 (substantial agreement) and SR2 was 0.67 (substantial agreement). Conclusions: Barzullah working classification of distal radius fractures presented in this study has good characteristics compared to those of already studied classification systems among orthopaedic residents.

Three Dimensional Models

The purpose of this study was to develop plates that fit the contour of the distal radius of the Japanese and can be inserted less invasively. Three-dimensional models of 36 radii of 18 volunteers were prepared. Using these models, the shape of the cortical bone on the radial margin of the distal radius and just below the dorsal fourth compartment of the wrist, to which the plates were expected to be applied, was measured, and the curves of the plates were determined. The functions of approximated curves of the plates were: [ y = -2 × 10-8 x 5 - 2 × 10-6 x 4 + 0.0006 x 3 - 0.0312 x 2 + 0.3274 x + 15.224 on the radial margin of the distal radius and [ y = 7 × 10-7 x 5 - 0.0001 x 4 + 0.0078 x 3 - 0.2355 x 2 + 3.1815 x - 5.6383 just below the fourth compartment. The clinical results of the application of double dorsal plates were satisfactory in clinical cases for the distal radius fractures.

INTRODUCTION Rupture of extensor pollicis longus (EPL) tendon is a recognised complication following volar plate fixation of distal radius fractures, usually from attrition caused by prominent screws. We sought to identify the screw holes in some of the most commonly used plates which may precipitate tendon injury. SUBJECTS AND METHODS Three fixed-angle volar locking plates were sequentially positioned into 18 cadaveric arms. A wire was passed through each of the holes in the plates using a locking guide and the dorsal relationships noted. RESULTS Each plate had specific ‘high-risk’ holes which directed the wire towards the EPL groove. The central screw holes appeared mostly implicated in EPL injury. CONCLUSIONS Awareness of ‘high-risk’ holes and appropriate minor alterations in surgical technique may consequently decrease the incidence of EPL irritation and rupture.
