We examined seven patients with tarsal tunnel syndrome in one foot caused by talocalcaneal coalition and a ganglion. We excised the coalition and the ganglion in six of them. All the patients had pain, sensory disturbance in the sole, and a positive Tinel's sign. Older patients with a long history showed atrophy and weakness of the plantar muscles. Talocalcaneal coalition can be diagnosed on a plain lateral radiograph and an anteroposterior radiograph externally rotated 20°, and confirmed by CT. MRI is also useful for diagnosis. The coalitions were medial, and the ganglion had developed from the incomplete part of the coalition; it was multilocular in some patients. After resection, there was early pain relief but sensory disturbances and Tinel's sign persisted. The postoperative results were excellent in one patient, good in four and fair in one.
