The authors have previously described four types of intrinsic contracture in the first intermetacarpal web space. They now report a fifth group in which all the muscles in the space are involved. In this condition the thumb is flexed and adducted, and there is also radial deviation of the index finger with hyperextension of the proximal interphalangeal joint. These deformities are produced by contractures of the adductor pollicis, the flexor pollicis brevis and the first dorsal interosseous muscles. Three patients with this type of contracture are described. Operation produced an excellent result in each case, but it is essential to achieve complete correction. in a prospective study
