摘要
目的:为临床应用尺侧腕屈肌转位重建屈肘功能提供解剖学依据。方法:本文在50例固定标本上解剖、观测了尺侧腕屈肌的位置形态、血供和神经支配。结果:肌平均长(25.04±20)cm;肌中部宽(2.60±O.1)cm;肌中间厚(0.65±0.3)cm。动脉在肌的近端,肱骨内、外上髁平面以下(3.60±0.7)cm处进入该肌。神经在肱骨内、外上髁平面以下(3.59±0.8)cm处进入该肌。结论:尺侧腕屈肌有足够的长度供转位应用。尺侧腕屈肌血供丰富,足可满足该肌的血液供应和神经支配的需要。根据血管神经蒂进入该肌的部位,手术时作肌的分离以及确立肌转位点,不应高于肱骨内、外上髁平面以下5 cm,否则易损伤该肌的血管和神经。
Objective: To provide anatomic materials for reconstruction of function of flexing elbow joint by the transposition of flexor carpi ulnaris for clinical practices. Method; The flexor carpi ulnaris and its nerves and blood vessel supplies were observed and measured on 50 cases of upper limb specimens in adult. Results; The length of flexor carpi ulnaris was 25.04 ±20 cm, the width and thickness of its middle portion was 2.60 ±0.1 cm and 0.65 ±0.3 cm respectively. The artery and nerve entered the flexor carpi ulnaris at 3.6 ±0.7 cm and 3.59 ±0. 8 cm beneath the line between the medial epicondyle of humerus and the lateral epicondyle of humerus respectively. Conclusion; The length of flexor carpi ulnaris is enough to translocate on operation and its nerves and blood vessel could meet the demand for the translocated flexor carpi ulnaris. The flexor carpi ulnaris will be separated and determined to transpose below the line between the medial epicondyle of humerus and the lateral epicondyle of humerus on operation, or the blood vessels and nerves of the flexor carpi ulnaris will be readily to be injured.
