摘要
目的 临床上钩骨钩部骨折比较罕见而常被误诊 ,故阐明其症状、影像学检查特点及手术疗效。方法 对 4例钩骨钩部骨折病史进行分析及文献复习。钩骨钩部骨折临床表现为腕部尺侧局限性压痛 ,腕部力量减弱。 4例的腕部正侧位X线片未能确诊而CT影像学表现则确诊为钩骨钩部骨折。 4例均作切开复位、螺钉内固定术和腕尺管切开术 ,其中 1例同时作腕管切开术。结果 术后随访 5～ 12个月 ,骨折均已愈合 ,症状消失。结论 钩骨钩部骨折的发病率低 ,易漏诊 ,是罕见而易被误诊的骨折。
ObjectiveFractures of the hook of the hamate are rare and comm on ly not identified in the acute phase. Four cases of hamate hook fracture are pre sented, along with a review of the literature. MethodsPatients presented with a cute onset of pain localised over the ulnar aspect of the wrist and reduction in grip strength. Diagnosis was confirmed by CT scanning. 0pen reduction and inter nal fixation with screws were performed in all 4 cases. The patients were follow ed for 5 to 14 months.ResultsBone healing was seen in all pati ents. Release of Guyon's canal was done in 4 cases, and carpal tunnel in 1 case. The clinical results were good. Mechanism, diagnosis and treatment options are discussed. ConclusionFracture of hamate hook is rare and easily misdiagnosed . CT scanning is the gold standard for diagnosis. Ulnar nerve is vulnerable in this type of frac ture, and release of the Guyon's canal is recommended.
