Evaluación de las relaciones entre la rama palmar profunda de la arteria ulnar y el ramo profundo del nervio ulnar en la región palmar / Evaluation of the relationship between the deep palmar branch of ulnar artery and the deep branch of the ulnar nerve in the palmar region

RESUMEN: Nos motivó esta presentación los hallazgos observados en la sala de disección sobre las relaciones de la rama palmar profunda de la arteria ulnar y el ramo profundo del nervio ulnar, las diferentes disposiciones de esta rama, el cruzamiento, cuando existe, entre ambos elementos y las pocas referencias sobre el tema, todo con miras a favorecer el abordaje profundo de la palma de la mano y contribuir al conocimiento del área en donde se practican las neurotomías del ramo profundo del nervio ulnar y/ o sus ramas.

SUMMARY: We are motivated by the findings observed in the dissection room on the relationship between the deep palmar branch of ulnar artery and the deep branch of ulnar nerve, the different dispositions of this branch, the crossing, when it exists, between both elements and the few references on the subject, all with a view to favoring the deep approach to the palm and contributing to the knowledge of the area where neurotomies of the deep branch of ulnar nerve and/or its branches are performed.

Imaging anatomic study of deep branch of ulnar nerve / 中华显微外科杂志

Objective To dissect and observe the course of the deep branch of the ulnar nerve and its'distribution of the muscular branch,to provide imaging and anatomical basis for early diagnosis and treatment of the wrist deep branch of ulnar nerve injury in clinical. MethodsFrom October 2008 to August 2010,dissected 16 fresh and 4 antiseptic samples, with the most bump of the hook of the hamate bone as the origin O,set the axis over the O point.The distance from O to the intersection point of the X axis and the deep branch of ulnar nerve was OE ; the distance from O to the intersection point with the ulnaris of hook of hamate bone was OF; the distance from O to the proximal deep branch of ulnar nerve intersection point of the Y axis was OG; the distance from O to the distal deep branch of ulnar nerve respectively was OH.Named the head of the metacarpal bone and the palm side of the center of the basal of the 2nd to the 5th metacarpal bone, through these two points,the measure related data from the deep branch of the ulnar nerve and the metacarpal bone in the sagittal plane.Having a CT scan image data,the Barium Sulfate ( Ⅱ ) dry suspension was uniformly smeared onto the surface of the deep branch of ulnar nerve, the data obtained was analyzed using SPSS 13.0.ResultsThe length of OE was ( 4.96 ± 0.11 ) mm,CT result was (5.02 ± 0.12 ) mm; the length of OF was (3.69 ± 0.12 ) mm,CT result was(3.75 ± 0.12)mm; the length of OG was(10.55 ± 1.07)mm,CT result was(10.48 ± 0.84)mm;the length of OH was (7.23 ± 0.85)mm,CT result was (7.29 ± 0.84)mm; the length of EF was (1.27 ± 0.15 )mm,CT result was( 1.17 ± 0.16)mm.The measure related data from the deep branch of the ulnar nerve and the metacarpal bone in the sagittal plane. Each data set of the anatomical results and CT results had been tested by T,P values were more than 0.05. ConclusionsThere is no significant difference between anatomic and CT observations of deep branch of ulnar nerve, CT observations can be regarded as a clinical reference directly.Anatomic and CT observations can be seen as a guide for clinical work in the diagnosis and treatment of deep branch of ulnar nerve injury.

Anatomical study of the third palmar interosseous muscle and its dominate nerve / 中华显微外科杂志

Objective To explore the anatomical characteristic of the third palmar interosseous mus- cle as well its dominate nerve,and to investigate the anatomical basis of difficult recovery of digitus minimus adduction.Methods Twenty aduh fresh hands without deformity and trauma were obtained.Dissect and observe the third palmar interosseous muscle and its dominate nerve and adjacent structure under surgical mi- croseope,measure the size of the third pahnar interosseous muscle and its dominate nerve,the data were pro- cessed by stastistics method.Results Among palmar interosseous muscles and its dominate nerves,the third palmar interosseous muscle and its dominate nerve is the smallest.There are conspicuous tendon bundle on the surface of the third palmar interosseous muscle partly,which have a potential compression on the third palmar interosseous muscle dominting nerve.Conclusion The third palmar interosseous muscle is the smal- lest among palmar interusseous muscles and it is the only digitus minimus adduction muscle.The sominating nerve of the third palmar interosseous muscle is small anti the tendon bundle of the third palmar interosseous muscle have a potential compression.All these can cast light on diffcult recovery of digitus minimus adduction.
