'Constriction Band Syndrome': Retained Rubber Band as a Less-Known Cause of Pain and Non-healing Sinus Tracts of Wrist in a Paediatric Patient.

Rubber band constriction syndrome has been described in the literature, although there are very few case reports. Non-healing recurrent tenosynovitis and synovitis of the wrist joint demonstrating a circular rubber band on imaging has not been described before. Imaging studies showed retained circular band deep to the extensor tendons, embedded within the joint capsule.
