The authors studied the course of the infrapatellar branch of the saphenous nerve in 36 cadaver legs, with particular reference to its relationship to the sartorius muscle. In 19 (52.8%) the infrapatellar nerve passed through the sartorius, in 15 (41.7%) it passed over the sartorius before distributing to the antero-medial aspect of the knee. In two the nerve branched: in one both branches penetrated the sartorius and in the other, one branch penetrated and the other passed over the sartorius. The authors could not find any case in which the nerve passed through the tendon of the sartorius or passed under the sartorius. These findings explain why few cases of entrapment neuropathy of the infrapatellar branch clinically need surgical treatment.

We report three cases of femoral nerve paresis. Case 1 was a 25-year-old male, who was admitted to hospital complainning of left thigh pain. On examination he had tenderness in his left inguinal area. Neurological examination revealed a weakess of the quadriceps on the left, and diminished sensation on the anteromedial aspect of his left lower extremity. The mechanism of injury was not clear in this case. Case 2, a 56-year-old male had progressive muscle weakness and numbness in the right lower extremity. He had received cobalt radiation therapy 16 years previously. Clinical examination revealed a firm hypertrophic scar with tenderness in the right inguinal area, and neurological examination showed quadriceps weakness and sensory disturbance of the anteromedial surface of the right thigh nd leg. Case 3, an 18-year-old male complained of gait disturbance and sever pain around theleft inguinal area and numbness over the left thigh. “The patient was a hemophiliac who had been unde the care of a pediatrician”.Neurolysis was performed in two cases, and the other patient was treated with bed rest and replacement therapy. In all cases, symptoms improved after treatment.

The authors dissected 72 paired arm to study the anatomy of Gantzer's muscle. The dissection explored course of the median nerve from the elbow to the distal end of the forearm. The following anatomical structures and variations were noted;(1) The presence of a Gantzer's muscle, as well as its relationship to the median and anteriorinterosseous nerves.(2) The origin and insertion of Gantzer's muscle.Results: Gantzer's muscle arose from the medial epicondyle of the humerus in 45 arms (90%), from the coronoid process of the ulna in 3 arms (6%), from the intermuscular fascia in 1 arm (2%), and from a double origin- the medial epicondyle and the coronoid presess-in 1 arm (2%). Insertion was to the proximal part of the tendon of the flexor pollicis longus muscle in all arms.Gantzer's muscle always lies posterior to the median nerve. In 12 out of 50 arms, the muscle passed posterior to the anterior interosseous nerve, and in the remaining 38 arms, the anterior interosseous nerve ran proximal to the muscle along its proximal border and never cross Gantzer's muscle and its tendon.Based on these findings, the authors concluded that Gentzer's muscle rarely contributes to anterior interosseous nerve compression in the proximal forearm.
