Abstract:
[Abstract] Objective To study the morphology, muscle architecture index and distribution pattern of intramuscular nerve dense area of elbow muscle, so as to provide anatomical location for poster-lateral approach of elbow joint and transplantation of elbow muscle flap. Methods Through gross anatomy, muscle architecture index and modified Sihler’s intramuscular nerve staining, 10 cases with an average age of 64. 2 years were selected. Results The elbow muscle was approximate triangle, the muscle wet weight was (6. 31±0. 85) g, the muscle length was (6. 24±0. 78) cm, the muscle fiber length was (4. 74±0. 88) cm, pennation angle(70. 60±6. 41)°and the muscle physiological cross-sectional area was (0. 41±0. 15) cm
