McBride and colleagues describe an innovative method which simplifies plaster immobilisation of the thumb (1) but could be improved by limiting the distal extent of the dressings to allow unrestrained mobilisation of the finger metacarpophalangeal joints (MCPJ). Although the plaster component of the dressing appears to stop at the MCPJ crease of index and middle fingers (Fig. 3), the wool and crepe dressings extend well beyond the MCPJ crease on all rays (Fig. 4). This is unnecessary and impedes flexion of the MCPJ which may ultimately cause stiffness and a reduced range of motion.
