Abstract
BACKGROUND: The current evidence base for the management of central slip avulsions is limited from obtaining a best approach. The purpose of this study was to evaluate the clinical effect and feasibility of repairing the fresh central slip avulsion by bone tunnel-tendon suture. METHODS: Twenty-four cases of open and closed central slip avulsions were prospectively studied. They were treated by suturing the tendon to the pre-holed bone through two parallel bone tunnels. Follow-up was conducted at 1 month, 3 months, 6 months, 12 months and 18 months after the operation. Symptoms, degree of satisfaction with the appearance, complications, Crawford's evaluation, DASH scores and the total active movement (TAM) were collected. RESULTS: The follow-up period was 6~18 months (mean 13 months). Finger function was assessed using the Crawford's evaluation criteria: excellent in 12, good in 10, average in 2, with an excellent and good rate of 91.7%. DASH scores ranged from 37 to 47(mean 39). According to the Chinese Medical Association's trial criteria for assessing the function of upper limbs, excellent, good and average cases were 9, 14 and 1 respectively. The range of motion gradually improved over time. Conclusions Good prognosis can be achieved through bone tunnel-tendon suture for the treatment of fresh central slip avulsion.
