Two cases of the femoral nerve injuriescaused by sport were reported. in one patient, the femoral nerve was overstretched during broadjump, and other was due to falling down duringskating in which the femoral nerve was compressedby the hematoma in the iliac fossa. The clinicalfeature showed paralysis of the anterior femoralmuscles and decreased skin sensation in both cases.Neurolysis of the femoral nerve and evacuation ofthe hematoma in the iliac fossa were conducted.The functions were recovered to normal after operation. The author pointed out that this kind of injury should be differentiated from the simple soft tissue injuries and the electromygram was helpful in the comfirmation of the diagnosis.
A new method of anterior decompression for thoracolumbar fractures with paralysi s in six cases was reported. In a follw-up of one to five months, was shown that the neurological functions in all six cases has improved ⅡⅢ rank in Frankl classification. The author believe that the method has the following advantages, such as: less trauma from operation; the level and the limit of decompression could be made without Xray during the operation; usually only 1/5 to 1/4 of the vertebral body was excised so that the stability of the spine was not disturbed, and the obvious favourable results.
