ABSTRACT
STUDY DESIGN: A case report. OBJECTIVES: To report and discuss an extremely uncommon cause of lumbar plexopathy seat belt injury. SUMMARY OF LITERATURE REVIEW: For patients who undergo traffic accidents, most cases of seat belt injury cause trauma to the lower torso. Seat belt injury is associated with variable clinical problems such as vascular injury, intestinal injury (perforation), vertebral injury (flexion-distraction injury), chest wall injury, diaphragmatic rupture/hernia, bladder rupture, lumbosacral plexopathy, and other related conditions. MATERIALS AND METHODS: A 38-year-old male truck driver (traffic accident victim) who suffered monoplegia of his right leg due to lumbar plexus injury without spinal column involvement. Injury to a lumbar plexus and the internal vasculatures originated from direct compression to internal abdominal organs (the iliopsoas muscle and internal vasculatures anterior to the lumbar vertebrae) caused by the seat belt. We have illustrated an extremely uncommon cause of a neurologic deficit from a traffic accident through this case. RESULTS: Under the impression of traumatic lumbar plexopathy, we managed it conservatively, and the patient showed signs of recovery from neurologic deficit. CONCLUSIONS: We need to review the lumbar plexus pathway, in patients with atypical motor weakness and sensory loss of the lower extremities which are not unaccompanied by demonstrable spinal lesions. Therefore, close history taking, physical examination and comprehension of injury mechanism are important in the diagnosis.

BACKGROUND: Bone mineral density (BMD) is known to have a positive correlation with lean body mass. Several studies have also reported the positive correlation between muscle power and BMD. From this point of view, we hypothesized BMD of lumbar spine to have a positive correlation with muscle mass. METHODS: Seventy-nine female patients aged between 60 and 75 years old and who underwent magnetic resonance imaging (MRI) and BMD studies were included. Muscle mass in spine MRI was defined by the sum of the average muscle area of three axial images for each disc level. Lumbosacral muscle is the sum of paraspinal muscle and psoas muscle. RESULTS: In correlation analysis, paraspinal muscle mass showed positive correlation with BMD of lumbar spine. Lumbosacral muscle mass showed positive correlation with BMD of trochanteric area of the femur. However, BMD of other area showed no significant correlation with muscle mass. CONCLUSIONS: Therefore, postmenopausal women older than 60 years with a well developed spine muscle mass, have a high BMD.

Congenital absence of the cruciate ligament is an extremely rare condition that was first reported in Giorgi's radiographic study in 1956. The authors report on a case of anterior cruciate ligament reconstruction performed on a 21-year-old female patient with congenital anterior cruciate ligament absence. We also discuss radiographic evidence that could provide clues to the congenital absence and possible difficulties that may be encountered during surgery with a review of the relevant literature.
