Open flexor tenotomy for hammer toes and curly toes in childhood

Description: Sixty-two children were reviewed between 3 and 14 years (average 9.8 years) after flexor tenotomy for curly toes or hammer toes. No patients were aware of loss of flexor power in the toes. In only 5% of 188 toes was the operation unsuccessful. When the cause of failure was identifiable it proved to be that the scar crossed one or more flexor creases. None of the operated toes had an abnormally extended posture; only one toe was stiff and this resulted from tethering by a scar. It is concluded that open flexor tenotomy is an effective method for correcting curly toes and hammer toes in childhood. Pre-operative assessment must demonstrate that the resting length of the flexor tendons is unduly short, and that this shortening is the only cause of the deformity.
