title: Unilateral spondylolysis combined with contralateral lumbar pediculolysis in a military parachutist.
abstract: A few cases of unilateral pediculolysis combined with contralateral spondylolysis have been reported, and most of them were related to athletic activities. A case of unilateral spondylolysis combined with contralateral lumbar pediculolysis in a military parachutist is reported. A 34-year-old man experienced low back pain and right sciatica for 3 months. Radiographs revealed a left spondylolysis combined with a right pediculolysis of the L5 vertebra. The patient had parachuted >300 times in the last 5 years. Interbody fusion of L5-S1 was performed, and the patient was free of pain after surgery.
