摘要
目的为外踝前血管胫骨远端前外侧骨膜瓣移位术提供解剖学依据. 方法 30侧经动脉灌注红色乳胶的成年下肢标本,观测外踝前动脉的起源、走行、骨膜支及与腓动脉穿支降支的吻合关系. 结果外踝前动脉有1～2支,起点在外踝尖上(1.1±0.4)cm,起始外径(1.6±0.4)cm,沿途发1～3支,外径为(0.4～0.8)mm的骨膜支分布胫骨远端外侧.腓动脉穿支起点在外踝尖上(5.6±0.5 cm),降支循外踝的前外侧下行,沿途向两侧发出2～6支外径为0.5～1.0 mm的骨膜支滋养胫骨远端前外侧和外踝.两者吻合部位在外踝尖上(1.7±0.6)cm,距外踝前动脉起点外侧(2.5±0.6)cm.吻合后动脉经趾短伸肌后部,沿腓骨短肌腱的前缘前行,终支与跗外侧动脉、跟外侧动脉相吻合. 结论以外踝前血管为蒂的胫骨远端前外侧骨膜瓣,可移位用于修复距骨颈骨折和距骨体缺血性坏死.
Objective To provide anatomical basis for transposition for the periosteal flap pedicled with the lateral anterior malleolus vessel on the anterior external of tibia distally based. Methods The origins, course, branches distribution, and anastomosis of lateral anterior malleous artery and periosteal vessels of the anterior external of tibia distally based were observed on 30 adult cadaveric feet. Results Lateral anterior malleolus arteies had 1～2 branches, whose diameters were(1.6±0.4)mm and the distances the above cusp of extrnal malleolys cusp were(1.1±0.4)cm, the arteries sent off the 1～3 pieces periosteum branches with diameter 0.4 to 0.8 mm, which distribute to the periostalr of anterior external of tibia distally based. To circulate anterior external of lateral malleouls of perforating descending branch of peroneal artery [the distances the above cusp of external malleolys cusp were (5.6±0.5)cm],the arteries sent off the 2～6 pieces periosteum branches with diameter 0.5 to 1.0 mm, which distributed to the periostealr of anterior external of tibia distally based and lateral malleolus. Both anastomosis site in the above cusp of external malleolys cusp were(1.7±0.6)cm, the distances the point of lateral anterior malleolus artery were(2.5±0.6)cm. The artery of anastomosis to undergo posterior of extensor digitorum brevis, along anterior border of tendon of short peroneal muscle, anastomosed with the lateral tarsal artery and the medial taesal atery. Conclusion It is an easy practical for repairing fracture of neck of talus fracture and ischemic necrosis of talus body to achieve the transposition of periosteal flap pedicled with the lateral anterior malleous vessel on the anterior external of tibia distally based.
