Abstract:
Objective To investigate the feasibility of endoscopy in diagnosis and treatment of compressed peripheral nerves. Methods An 1.5 cm transverse incision posterior to the margin of pectoralis major along the second rib was made in 2 old and 9 fresh cadaver specimens. The distance from the incision to the insertions of anterior and middle scalene muscle on the first rib was measured at various angles. The structures surrounding the approach was observed and measured to find a safer approach for endoscopic treatment of brachial plexus compression syndrome. Results With the upper limb hyperabducted at 120 degrees, anteriorly tilting at 30 degrees, through an 1.5 cm transverse incision made posteriorly to the margin of pectoralis major and along the second rib, the apparatus was inserted toward the point 6.5 cm laterally apart from the sternoclavicular articulation and 7.8 cm in depth, reaching the insertions of the anterior and middle scalene muscle on the first rib without injury to the nerves and vessels. Conclusion The approach is safe for endoscopic apparatus reaching the insertions of the anterior and middle scalene muscles on the first rib. It also provides a basis for further investigation of cutting anterior and middle scalene muscles through endoscope.
