Fractures of the capitellum can involve a significant portion of the articular surface, rendering the elbow joint unstable. In this situation it is desirable to reduce and internally fix the capitellar fragment, because this restores the articular surface and augments joint stability. A 35-year-old woman sustained a posterolateral dislocation of the left elbow associated with a capitellar fracture. Fixation of the capitellar fragment with Herbert screws stabilized the joint, allowed anatomic reduction, and gave good fixation. Active motion was possible at three weeks. When the patient was evaluated at one year, the fracture had united and there was no evidence of avascular necrosis.
肱骨小头骨折可能累及大部分关节面,导致肘关节不稳定。在这种情况下,对肱骨小头骨折块进行复位和内固定是可取的,因为这可以恢复关节面并增强关节稳定性。一名35岁女性发生左肘关节后外侧脱位并伴有肱骨小头骨折。用Herbert螺钉固定肱骨小头骨折块稳定了关节,实现了解剖复位,并提供了良好的固定效果。三周时即可进行主动活动。患者在一年后接受评估时,骨折已愈合,且没有缺血性坏死的迹象。
