การศึกษาหลอดเลือดและเส้นประสาทที่เข้าสู่กล้ามเนื้อที่นิยมใช้ในการปลูกถ่ายกล้ามเนื้อ / ดาวินี ชิณวงศ์ = The study of neurovacular pedicle of muscle commonly used for muscle transferring / Dawinee Chinnawong
Muscles commonly used for transferring are sartorius, gracilis, vastus lateralis, rectus femoris and flexor hallucis longus. The anatomical knowledge of neurovascular pedicle is important for surgeons because it helps to decrease iatrogenic injury during surgery. The aim of this study was to describe the length of neurovascular pedicle, distance from origin of muscle to the point of neurovascular pedicle entering the muscle, number and diameter of neurovascular pedicle and pattern of nerve split. This study was performed in 60 lower extremities. The results revealed the mean of the length of nerve pedicle of sartorius, gracilis, vastus lateralis, rectus femoris and flexor hallucis longus muscle was 5.0±1.9, 7.7±1.8, 7.3±2.2, 5.2±1.2 and 7.4±2.5 cm. respectively. The mean of the length of vascular pedicle of sartorius, gracilis, vastus lateralis, rectus femoris and flexor hallucis longus muscle was 3.2±1.3, 7.8±1.8, 7.1±1.9, 4.4±1.4 and 11.1±1.7 cm. respectively. Distance from origin of sartorius, gracilis, vastus lateralis, rectus femoris and flexor hallucis longus muscle to the point of nerve and vascular pedicle entering the muscle was 11.7±3.7, 9.2±1.8, 12.1±3, 11.8±2.2 and 7.2±2.8 cm. respectively. Distance from origin of sartorius, gracilis, vastus lateralis, rectus femoris and flexor hallucis longus muscle to the point of nerve and vascular pedicle entering the muscle was 10.9±3.6, 10.2±1.8, 12.9±3.1, 13.3±2.4 and 8.2±1.9 cm. respectively. Sartorius, gracilis, rectus femoris and flexor hallucis longus muscle were supplied by 1 nerve pedicle. Vastus lateralis was supplied by 2 nerve pedicle. Gracilis and rectus femoris were supplied by 1 vascular pedicle. Vastus lateralis was supplied by 2 vascular pedicle. Sartorius and flexor hallucis longus muscle were supplied by 3-4 vascular pedicle. The finding of this study may decrease risk and iatrogenic injury during operation.
