We discuss a combination of established and modern techniques in the investigation and management of traumatic flexor digitorum profundus rupture ('Rugger Jersey Finger') in seven cases (male rugby players ranging from 15 to 30 years of age; mean = 26). We discuss the use of X-ray and ultrasound investigation followed by various surgical repairs including intraosseous sutures, suture anchors, tendon lengthening and "pull-through suture over button" repairs. Functional outcome at outpatient follow-up is discussed in each case. Type I, II and Vb injuries were identified. Patients presenting early attained good functional outcome. Six patients received surgery within ten days of injury and attained satisfactory outcome at follow-up. One patient presented late and required a tendon lengthening procedure to manage myostatic contracture. Ultrasound imaging proved valuable in diagnosis and pre-operative planning. Numerous surgical repairs were used and all associated with a positive outcome providing there is adequate patient compliance.
