目的:探讨牵拉肘发病机制与桡骨头颈、环状韧带、滑膜皱襞的关系。
方法:对16侧婴幼儿和10侧学龄前儿童肘关节桡骨头颈、环状韧带、滑膜皱襞进行解剖观察测量。
结果: 桡骨头矢状径、横径均大于相应桡骨颈矢状径、横径(24%～30%),环状韧带上下缘弧长接近(婴幼儿26.82、26.57mm,学龄前儿童28.50、27.65 mm),桡骨头后内侧、前外侧滑膜皱襞恒定存在,基底宽大,游离缘长(婴幼儿9.55mm,学龄前儿童11.38mm),形态多样。
结论:环状韧带或滑膜皱襞嵌入肱桡关节间是引起牵拉肘发病的重要因素,该机制可以解释牵拉肘的临床表现。 |

Abstract:
Objective:To explore the pathologic mechanism of the pulled elbow with the relationship of the annular ligament and synovial fold in childhood
Methods:The embalmed cadsver's elbows in 16 infants and 10 pre-school children were dissected. The radial head and neck, annular ligament and synovial fold were observed and measured.
Results:The sagittal and transverse diameter of the radial head were larger than the diameters of the radial neck (24% -30% ). The superior and inferior lengths of the annular ligament were approximately similar (26.82 and 26.57 mm in infant,28.50 and 27.65 mm in pre-school children). The constant and multi-shape synovial fold were found at the postero-medial and antero-lateral area of the radial head. The free margin of the fold was long (9.55 mm in infant and 11.38 mm in pre-school children) with broad and thick basement.
Conclusion:Part of annular ligament or synovial fold interposed between the capitellum and the radial head could explain the mechanism of the pulled elbow. |
