Cadaveric Study of Berretini Communications in North Indian Population.

Intercommunication between peripheral nerves deserves special attention in view of their clinical significance. Superficial palmar communication between the median nerve and ulnar nerve is referred to as Berrettini Anastomosis. The presence or absence of this communicating branch varies between individuals. Earlier, incidence of Berretini communication reported varied significantly (4-94%). The aim of this study was to find out the frequency with which Berretini communication is found in North Indians. The present study was conducted on 60 upper limbs of 30 cadavers at the Government Medical College, Amritsar. The whole course of the median nerve and the ulnar nerve was exposed. Communicating rami in the hand were identified, cleaned and photographed. In all the six (10%) variant limbs, the communicating branch originated from lateral common palmar digital branch of ulnar nerve and joined medial common palmar digital branch of median nerve. Single communication with oblique course was seen in all the variants. Further, its ontogeny and clinical implications have been discussed in detail. The Berretini anastomosis was seen in 10% upper limbs of the present study. Damage to the communicating branch or the severing of the branch might result in sensory loss which may be difficult to diagnose owing to the large number of variations in the origin of the communicating branch. The patterns of sensory impairment may vary depending upon the branch of median and ulnar nerve it is seen connecting.

Fibrolipomatous hamartoma of the digital branches of the median nerve

Fibrolipomatous Hamartoma is an idiopathic disorder which may be related to hypertrophy of mature fat cells and fibroblasts in the epineurium. It is a rare condition most commonly affects the median nerve. Presentation is usually before 30 years of age.Some of them are presented with signs and symptoms of nerve entrapment and some are associated with macrodactyly (macrodystrophia lipomatosa) with gross cosmetic abnormality. MRI can be an important preoperative diagnostic tool. Biopsy and histopathology report can confirm the pathology.This report describes a case of Fibrolipomatous Hamartoma of the digital branches of left index and middle fingers of median nerve associated with macrodactyly. A 25-year old male patient having this problem came to Apollo Hospitals Dhaka with abnormally large left index and middle finger. Debulking by excision of the lipomatous tissue along the digital branches of median nerve was performed. Three weeks postoperatively, the patient had no major complaints and the mass decreased in size without any motor or functional losses. Sensory function also found near normal with a small area of numbness at the tip of the left index finger.DOI: http://dx.doi.org/10.3329/pulse.v4i1.6967Pulse Vol.4 January 2010 p.40-42
