The human hand represents a revolution in evolution. The muscles of the lumbricals though small in size, have a significantly greater role to play in the intricate movements of the fingers. These muscles show anomalous origins and insertions. Hence, this study was an effort to know more about these muscles, as it is of significant value in the design of surgical procedures.
This study was conducted on 30 (both in the male and female populations) cadavers which were available from the Department of Anatomy. Dissection was carried out according to the Cunningham’s manual of practical anatomy.
In the present study, many split insertions and misplaced insertions and even the absence of these muscles were noted. Apart from the anomalies in the attachments, the length, breadth, width and tendon length of all these intrinsic muscles were studied and noted.
In this study, the values of length, breadth, width and tendon length of all the lumbricals, was measured. On applying the test of significance, these values were found to be statistically significant.
