THE TYPES OF THE SURAL ANASTOMOTIC NERVE / 解剖学报

ABSTRACT

The writer observed the sural anastomotic nerve on 276 lower limbs from 138 corpses, including 11 adults and 127 new-borns (84 male, 54 females). It was found that sural anastomotic nerves are present in 219 cases (79.3%) and absent in 57 cases(20.7%). The ways of anastomosis of these nerves fall into the following four types (1) Type A The sural anastomotic and lateral sural cutaneous branches arise from peroneal nerve with a common trunk—108 cases (49.7%). (2) Type B The sural anastomotic nerve is one of the terminal branches of thelateral sural cutaneous nerve—48 cases (21.9%). (3) Type C The lateral sural cutaneous nerve arises from sural anastomoticnerve—35 cases (16%). (4) Type D The lateral sural cutaneous and sural anastomotic branches arise separately from the common peroneal nerve—28 cases (12.8%).
