Anomalous pattern of insertion in interossei and lumbrical's hands

ABSTRACT

Anomalous patterns in comparison to those described in standard anatomical text, books about distal insertion of interossei and lumbricul muscles in the hand among 112 freshly embalmed upper limbs from both sexes were investigated during dissection in the Department of Anatomy, King Edward Medical College. Maximum anomalies were observed in the distal insertions of palmar interossei [65.2%] as compared to dorsal interossei [19.8%] and lumbricals [9.8]. Among palmar interossei, higher number of anomalous attachements were found in 1st, and 4th interosseous muscles
