Surgery for Cerebral Palsy Part 3: Classification and Operative Procedures for Thumb DeformityFrom the Department of Hand Surgery and Peripheral Nerve Surgery, Royal North Shore Hospital, the University of Sydney and the Spastic Centre of New South Wales, Australia Correspondence: Mr Michael A. Tonkin, Department of Hand & Peripheral Nerve Surgery, Royal North Shore Hospital, St Leonards, NSW 2065, Australia. E-mail: mtonkin{at}surgery.usyd.edu.au Spastic thumb deformity is the result of imbalance between intrinsic and extrinsic forces acting across unstable joints. This paper presents a classification of spastic thumb deformity based on the accurate assessment of the deforming forces, outlines methods for their correction and reviews the results of our surgery. Thumb reconstruction procedures were performed in 32 patients with 33 spastic thumb deformities. All patients were assessed pre- and postoperatively using the same functional assessment system which was performed by the same team. The thumb was maintained out of the palm in 29 patients and lateral pinch was established in 26 patients.
