| Objective:Research the obturator nerve of its line feed,and its length, width,thickness and so an; The hip joint of obturator nerve branch from thestarting position and obturator membrane mouth distance, direction,distribution and transverse diameter; Observe and record any pair ofobturator nerve vice obturator nerve and the presence of a hip. Purpose isto have better understand the obturator nerve basin and their hip anatomy,to provide the anatomical data for clinical surgery for hip arthritis.Materials and methods:20(male17, female3, a total of40) formalin fixed adult specimen,specimen is complete, obturator nerve retained in good condition, age isunknown. Observation records within the basin of obturator nervesegment, of the length, width and thickness; The hip joint branch ofobturator nerve; Presence of obturator nerve.The results:1.Obturator nerve within the basin from lumbar nerve, to downwardthrough the psoas major, close to the sacroiliac joint in front across theside of the pelvis, and marching along the lateral pelvic wall above theobturator vessels into the membrane tube mouth is closed. Length of96.73±12.36mm, wear a big waist muscle of the obturator nerve width was1.93±0.35mm, thickness is1.82±0.32mm; Obturator nerve basinwithin the period of midpoint width of2.52±0.61mm, the thickness of1.43±0.34mm; Obturator nerves before the line went into the film holeclosed width was3.92±0.78mm, thickness1.140.21mm. obturatormembrane section of the length of the obturator nerve was20.16±4.15mm.2. The hip up since the basin within the period of28cases, from themembrane tube mouth closed a maximum distance of26.76mm; Fromthe tube segment in12cases. Hip hengjing is0.76±0.18mm, obturatornerve into before and after, the first branch of the obturator nerve, onlypart of a hip, while the following branch of the obturator nerve is a hip.3. Within the basin and the tube from the hip in a obturator membranemouth after menostasis hole deep muscle outside changes under themuscle to the outside surface or wear out, medial femoral circumflexartery and obturator artery or the line with the hip joint branch. Closedmembrane outside the pipe section after the issue of hip and the hip fromthe basin and the tube in tube outside of basic consistent. And tubeoutside the hip from the branch, amenorrhea before the hole outside theedge of the muscle and the iliopsoas muscle deep surface have hip again.The hip joint branch of the majority of type1. 4. Deputy obturator nerve for a variation of obturator nerve branch, in thebasin within the period of the inside, in front of a decline in pubic, deepto the pectineus surface can make1small teams to arrive at the hip.Experimental vice obturator nerve were found in2cases, including3patients with a hip.Conclusion:1. The length of the obturator nerve basin within a period of about100mm, can consider to shift from the length of the lumbar skeletons repairdegloving injury.2. The hip a majority within the basin. Segment within the basin, tube andpipe outside section of the hip after menostasis membrane tube throughthe obturator membrane downward hip. And from the outside of pipesection of the hip joint branch of the former branch of amenorrhea holeoutside edge of the muscle and arrive at the hip by iliopsoas muscle deepsurface again.3The pot is better than the basin into the road, but from outside the pipesegment with former vice the hip joint branch of the obturator nerve andthe cut does not belong to this column. |
