MORPHOLOGY OF PRONATOR QUADRATUS MUSCLE: A CADAVERIC STUDY
Journal Title: International Journal of Medical Research & Health Sciences (IJMRHS) - Year 2014, Vol 3, Issue 4
Abstract
Objective: Pronator quadratus plays an important role in movement and stabilization of radius and ulna in distal radio-ulnar joint and used as a flap in traumatic injuries of the distal part of the forearm. Aim: The aim of this study was to delineate the morphology of pronator quadratus muscle. Material and methods: A total of 60 forearms (Rt- 30; Lt-30) from 30 Indian cadavers were evaluated. Careful dissection of each forearm was done and extent of radial and ulnar attachments of pronator quadratus, width of proximal and distal borders of it was taken. Also, observed additional heads, attachment of origin and insertion of pronator quadratus muscle. Results: Width of proximal and distal borders of pronator quadratus were 28.6mm and 30.2mm respectively on right side and on left it was 28.7mm and 30.1 mm respectively. It had a single head in 33.33%, double heads in 60.00% and three heads in 06.66%. Extents of its radial and ulnar attachments were 45.1 mm and 45.4 mm on right side and 45 mm and 45.5mm on left side respectively. Conclusion: These observations have significant value and are applicable to plastic surgeons, clinicians, anatomists and this study will provide additional information for them.
