'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. Surgical removal of the band by open incision led to a dramatic improvement in the outcome of the patient. Level of evidence V.
