OBJECTIVE To investigate the surgical outcome of a universal pedicle screw-V rod system and isthmic bone grafting for isthmic spondylolysis. METHODS Twenty-four patients with isthmic spondylolysis at L5 and grade 0-I spondylolisthesis (Meyerding classification) received isthmic bone graft and stabilization using the universal pedicle screw-V rod system. Back pain was evaluated using the visua...

Abstract Background If bone union is expected, conservative treatment generally selected for lumbar spondylolysis. However, sometimes treatments are unsuccessful. We sought to determine the factors associated with failure of bony in acute unilateral spondylolysis marrow edema including contralateral pseudarthrosis. Methods This study targeted treated conservatively high school or younger studen...

Background: Lumbar spondylolysis is a common fatigue fracture of the pars interarticularis lamina lumbar spine in adolescent athletes presenting with clefts. Some pseudarthrotic causes low back pain or radiculopathy. This study presents case that was successfully treated using modified smiley face rod technique.

STUDY DESIGN This was a prospective pilot study to investigate the global motion characteristics of the spondylolysis and spondylolisthesis populations. OBJECTIVES The aim of this study is to determine the influence of a spondylolisthesis or a spondylolysis on global spinal motion and to establish whether this is dependent on the cause of the slip or the degree/grade of the slip. SUMMARY OF...

While 22 articles have reported on sacral stress fractures, it is a rare injury and its etiology is not well known. We present the case of a 16-year-old male who presented with low back pain in 2015. He was a high school soccer player with a previous history of a bilateral L5 lumbar spondylolysis in 2014. The patient refrained from soccer and wore a brace for six months. Two months after restar...

Spondylolysis is a common cause of backache and the detection of subtle cases is therefore important. Oblique views considerably increase the detection rate (Appleby and Stabler 1969), but a number of cases require additional views. The 30#{176} oblique cranial tilt view is more reliable than the standard oblique views in detecting spondylolysis as it visualises the pars interarticularis tangen...
