Abstract

Abstract:

BACKGROUND: The absorbable bone anchor is a new internal fixation method.
OBJECTIVE: To compare the clinical outcomes the metal splint external fixation and absorbable bone anchor system in treatment of closed mallet finger in early stage.
METHODS: Forty cases of closed mallet fingers were selected, 24 cases were treated with the metal splint external fixation and 16 cases were treated with absorbable bone anchor system. The time from injury to treatment was less than 1 week. The clinical data and surgical outcomes of the patients were retrospectively analyzed, and the excellent and good rate of two groups was compared with statistical analysis.
RESULTS AND CONCLUSION: All patients were followed-up for 4-14 months. Reference to the International Institute of Hand Surgery recommended TAM system, the excellent and good rate was 66.7% in the metal splint external fixation group and 93.8% in the absorbable bone anchor system group, exhibiting a significant difference between two groups (P < 0.05). There were two cases of recurrence in the metal splints external fixation group, one at 4 months and the other at 6 months after treatment. There was one case of local swelling and skin redness n the absorbable bone anchor system during functional training and these symptoms were improved after physical therapy. It indicated that the effect of the absorbable bone anchor system is significantly better than that of the metal splint external fixation. Absorbable bone anchor system is the first choice for the treatment of early closed mallet finger with the simple surgical procedure and the certain effect. However, the expensive price limits its wider application. Metal splint is easy to operate, but difficult to manage and the relapse rate is high during treatment.
