Humerus Muscle Tube Anatomic Research And Clinical Application

Objective:Humerus muscle tube travel have radial nerve and accompanyingbrachial deep artery, fluently with next mouth. Brachial deepartery through the humerus muscle tube divided into teamsbefore and after branch, the former branch also called radialcollateral artery. Because of the existence of the humerusmuscle tube radial nerve this important structure, so easilyhumeral fractures with radial nerve injury. Humerus muscle tubeanatomic study can be understand the humerus muscle tube’s ownproportion positioning of radial nerve vulnerability getknowledge and understanding of the radial nerve compressionsyndrome of good hair to the attention of the parts, and at thesame time avoid iatrogenic radial nerve damage. But to thehumerus muscle section of the radial nerve blood supply forclinical research related repair surgery provide theoreticalfoundation. The radial nerve in the humerus muscle tube nearbybranch of the study, to provide theoretical basis for radialnerve anastomosis. In addition, can be used with brachial deepvascular pedicle humerus disc shift technology bone repairsurgery.Methods This paper take40with (male,30cases of female10cases) usedfor the teaching of anticorrosive body specimens, local anatomyresearch. Measuring the radial nerve in the arm about distancedata; Radial nerve musculoskeletal tube ends up and down fromthe internal and external condyle attachment point distance;Radial nerve musculoskeletal tube and humerus length betweenthe proportion of their location value; Provides the basis forthe flap transplantation flap vascular related measurementdata; To understand the distribution of the radial nervenutrient vessels; Tricep each muscle branch issued a point,into the muscle point and no damage separation length and thelength of the damage separation related measurement.The results:1. The humerus muscle pipe flowing about the humerus2/5place,next mouth about in the1/3of the humerus.2. In the radial nerve enter and wear a humerus muscle tube whenthe position relative to determine3. Radial nerve in the arm about distance, humerus muscle tubeat the entrance to the humerus recently end distance average(117.34+6.58) mm, humerus recently end to lateral muscle spacing distance average (176.91+10.90) mm, humerus maximumlong average (305.58+17.76) mm.4. Radial nerve musculoskeletal tube ends up and down from theinternal and external condyle attachment point distance asfollows, left radial entrance to internal and external condyleof the humerus attachment point distance average (15.72+1.75)cm, the right radial entrance to internal and external condyleof the humerus attachment point distance average (16.24+1.71)cm,; The left radial export to internal and external condyleof the humerus attachment point distance average (9.4+1.33)cm, the right radial export to internal and external condyleof the humerus attachment point distance average (9.7+1.13)cm.5. Radial nerve musculoskeletal tube and humerus length betweenthe proportion of their location value: the left radial nervemusculoskeletal tube and humerus length between the proportionof their location value average (56.4+3.9)%, left radialentrance to internal and external condyle of the humerusattachment point and the ratio of the length of the humerusaverage (34.2+4.5)%, The right radial export to internal andexternal condyle of the humerus attachment point and the ratioof the length of the humerus average (59.8+5.1)%, the right radial export to internal and external condyle of the humerusattachment point and the ratio of the length of the humerusaverage (35.9+3.1)%.6. Flap vascular measurement data: radial side return arterylength (3.0+1.1) cm, artery diameter (2.1+0.2) mm, veinoutside diameter (2.2+0.5) mm; Radial collateral arterylength (3.6+1.0) cm, artery diameter (1.6+0.3) mm, veinoutside diameter (1.5+0.2) mm.7. Radial nerve nutrient vessels distribution: vice artery inthe second branch point distance humerus condyles outside onthe distance to (13.47+/-0.62cm, is apart from theepineurium distance for (0.56+/-0.16cm.8. Dolichocephaly muscle branch and the lateral head musclebranch without damage separation length: dolichocephaly musclebranch no damage separation length (49.02+9.64) mm; Thelateral head muscle branch no damage separation length (45.31+9.45) mm.Conclusion:1. The humerus muscle tube fluently with next mouth place,radial nerve position relatively fixed, easily damaged. 2. Humerus muscle tube lower segment for radial nervecompression good hair parts.3. Brachial triceps muscle branch of the nondestructive freefor the intercostal nerve and brachial triceps muscle branchof the anastomosis.4. Brachial deep artery can be used for vascular pedicle bone(film) disc upward shift technology, the treatment of humerus,period of nonunion or bone defect.5. Radial nerve in the arm of the main nutrient vessels in viceartery and radial collateral artery, intraoperative should tryto avoid its damage.
