Unexplored parameters of ulnar nerve in the palm and its clinical implications; A cadaveric study

Background: Biliary ductal region being frequently abnormal has been the subject of research since long time for anatomists, surgeons and radiologists as well.Methods: The present study was carried out in the department of Anatomy at PGIMS, Rohtak on 50 specimens of liver taken unblock with associated structures.Results: Accessory hepatic and accessory cystic ducts were observed in 4% cases each. 2% cases exhibited abnormal low fusion of cystic duct with common hepatic duct.Conclusions: These anomalies may add to postoperative complications if ignored. Present study is a step in the direction of creating awareness about these variations among the clinicians.

Introduction: This paper reports anatomical study of nature, incidence, innervation and clinical implications of Flexor Pollicis Brevis muscle (FPB). Material and Methods: The anatomical dissection of 60 limbs from 30 cadavers were performed in the Department of Anatomy of Medical School of Catholic University of São Paulo. Results: The superficial head of FPB has been innervated by the median nerve in 70% and in 30% it had double innervation. The deep head of FPB were absent in 14%, in 65%, occurred a double innervation. In 17.5% by deep branch of ulnar nerve and in 3.6% by recurrent branch of median nerve. Conclusion: The pattern of innervation more frequent in relationship to the flexor pollicis brevis muscle and should be considered as a normal pattern is that superficial head receives innervation of branches of median nerve and the deep head receives innervation of ulnar and median nerve.

Fresh Frozen

Ten fresh frozen right cadaver arms were placed in a motorized jig and an in-situ ulnar nerve decompression was performed in 5 mm increments distally to the flexor carpi ulnaris (FCU) aponeurosis then proximally to the intermuscular septum. The elbows were ranged 0–135° after each incremental decompression and the ulnar nerve to medial epicodyle distance was measured to assess for nerve translation/subluxation compared with baseline (prerelease) values. None of the specimens had ulnar nerve subluxation (defined as anterior translation past the medial epicondyle) even after full decompression. Furthermore, there were no statistically significant ulnar nerve translations (defined as any difference in distance from ulnar nerve to medial epicondyle before and after each decompression) for any flexion angle or extent of decompression. This study provides biomechanical evidence that in situ ulnar nerve decompression from the FCU aponeurosis to the intermuscular septum does not result in significant ulnar nerve translation or subluxation.

Careful Observation

Background. Descriptive evaluation of nerve variations plays a pivotal role in the usefulness of clinical or surgical practice, as an anatomical variation often sets a risk of nerve palsy syndrome. Ulnar nerve (UN) is one amongst the major nerves involved in neuropathy. In the present anatomical study, variations related to ulnar nerve have been identified and its potential clinical implications discussed. Materials and Method. We examined 50 upper limb dissected specimens for possible ulnar nerve variations. Careful observation for any aberrant formation and/or communication in relation to UN has been carried out. Results. Four out of 50 limbs (8%) presented with variations related to ulnar nerve. Amongst them, in two cases abnormal communication with neighboring nerve was identified and variation in the formation of UN was noted in remaining two limbs. Conclusion. An unusual relation of UN with its neighboring nerves, thus muscles, and its aberrant formation might jeopardize the normal sensori-motor behavior. Knowledge about anatomical variations of the UN is therefore important for the clinicians in understanding the severity of ulnar nerve neuropathy related complications.
