Abstract:
To explore the clinical classification of hamate hook fracture and the treatment strategy for different type of fractures, 12 patients who suffered from hamate hook fractures were followed up retrospectively. According to the fracture sites and the prognosis, we classified the hamate hook fractures into 3 types. Type I referred to an avulsion fracture at the tip of hamate hook, type II was a fracture in the middle part of hamate hook, and type III represented a fracture at the base of hamate hook. By the classification, in our series, only 1 fell into type I, 7 type II, and 4 type III. The results were evaluated with respect to the functional recovery, recovery time and the association among the clinical classification, pre-operative complications and treatment results. The average follow-up time of this group was 8.4±3.9 months. Two cases were found to have fracture non-union and both of them were type II fractures. Six patients had complications before operation. Five cases were type II fractures and 1 case type III fracture. All the patients were satisfied with the results at the time of the last follow-up. Their pain scale and grip strength improved significantly after treatment. All the pre-operative complications were relieved. The recovery time of hamate hook excision was significantly shorter than that of the other two treatments. The incidences of both pre-operative complications and non-union in type II fractures were higher than those in type I and type III fractures. It was concluded that, generally, the treatment effects with hamate hook fracture are quite good. The complication incidence and prognosis of the fracture are closely related to the clinical classification. Early intervention is critical for type II fractures.
