Objectives/Interrogation: To evaluate the treatment effects of coronal fracture of the hamate with fixation of titanium miniplate crossing carpometacarpal joint.

Methods: From December 2011 to June 2015, 17 patients suffered from coronal fracture of the hamate were treated with fixation of titanium miniplate crossing carpometacarpal joint. The patients were all males, aged from 18 to 43 years, average (28.9±7.0) years. According to the classification of Ebraheim's hamate body fracture, 2 cases were type A, 5 cases were type B, 10 cases were type C. All the hamate fractures were exposed by dorsal approach. After the reduction, the fractures were fixed with titanium miniplate crossing carpometacarpal joint dorsally. The Disabilities of the Arm, Shoulder and Hand (DASH), visual analogue scale (VAS), MAYO Wrist Score, grip strength and ring and small fingers total active motion (TAM) were employed to evaluate the functions. All patients took X rays during follow-up.

Results and Conclusions: All 17 patients were followed up from 13 to 42 months, average (18±7) months. Hamate fractures were healed from 6 to 10 weeks, average (7.1±1.1) weeks. Except two cases, all titanium miniplates and screws were removed at 3 to 4 months post-operatively. At final follow-up, DASH scores were from 0 to 10.8, with an average 1.9±3.5. MAYO Wrist Scores were from 65 to 100, with an average 93.8±10.7. Grip strength averaged (42.4 ± 4.8) kg on the injured side and averaged (41.6 ± 2.9) kg on the contralateral side. TAM of the ring and small fingers were 280°±5° and 271°±6° on the injured side, meanwhile 281°±3° and 272°±4° on the contralateral side. Grip strength and TAM of both sides showed no statistical significance.

Coronal fracture of hamate could be fixed with titanium miniplate crossing carpometacarpal joint. The procedure could provide stability and allow early motion, which could help maintain joint reduction and obtain reliable fracture healing and good hand function. This technique may be an optional choice in clinical practice.
