Study Design: Retrospective study. Purpose: This study aimed to investigate whether segmental lumbar hyperlordosis of the affected vertebra in patients with spondylolysis occurs only at L5 or also occurs at L4. Overview of Literature: To the best of our knowledge, increase in segmental lordosis of the spondylolytic vertebrae has only been investigated in bilateral L5 spondylolysis; it has not been examined at different levels of bilateral spondylolysis. According to the characteristics of segmental lordosis in bilateral L5 spondylolysis, patients with bilateral L4 spondylolysis may also have increased segmental lordosis of the L4 vertebra. Methods: Patients with bilateral spondylolysis of the L5 or L4 vertebra in 2013-2015 were retrospectively identified from the hospital database. Standing lateral lumbar radiographs were assessed for the angle of segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis. The differences in segmental lordosis of the L5 and L4 vertebra, sacral slope, and lumbar lordosis were determined using non-paired Student t-test. Results: Overall, 15 cases of bilateral L4 spondylolysis and 41 cases of bilateral L5 spondylolysis satisfied the inclusion and exclusion criteria. Lordosis of the L4 vertebra was significantly greater in the bilateral L4 spondylolysis group ($24.2^{\circ}{\pm}7.0^{\circ}$) than that in the L5 spondylolysis group ($20.3^{\circ}{\pm}6.1^{\circ}$, p=0.047). Lordosis of the L5 vertebra was significantly lower in the L4 spondylolysis group ($27.7^{\circ}{\pm}8.2^{\circ}$) than that in the L5 spondylolysis group ($32.5^{\circ}{\pm}7.3^{\circ}$, p=0.040). The sacral slope and lumbar lordosis did not significantly differ between the groups. Conclusions: Adolescent patients with bilateral spondylolysis have segmental hyperlordosis of the affected vertebra not only at the L5 level but also at the L4 level.

Objective : To compare spinopelvic parameters in young adult patients with spondylolysis to those in age-matched patients without spondylolysis and investigate the clinical impact of sagittal spinopelvic parameters in patients with L5 spondylolysis. Methods : From 2009 to 2012, a total of 198 young adult male patients with spondylolysis were identified. Eighty age-matched patients without spondylolysis were also selected. Standing lateral films that included both hip joints were obtained for each subject. Pelvic incidence (PI), sacral slope (SS), pelvic tilt, lumbar lordosis angle, sacral inclination, lumbosacral angle, and sacral table angle were measured in both groups. A comparative study of the spinopelvic parameters of these two groups was performed using SPSS 15.0 (SPSS Inc., Chicago, IL, USA). Results : Among the aforementioned spinopelvic parameters, PI, SS and STA were significantly different between patients with spondylolysis and those without spondylolysis. PI and SS were higher in the spondylolysis group than in the control group, but STA was lower in the spondylolysis group than in the control group. Conclusion : PI and SS were higher in the spondylolysis group than in the control group, but STA was lower in the spondylolysis group than in the control group. Patients with spondylolysis have low STA at birth, which remains constant during growth; a low STA translates into high SS. As a result, PI is also increased in accordance with SS. Therefore, we suggest that STA is an important etiologic factor in young adult patients with L5 spondylolysis.

Bilateral pedicle stress fracture is a rare entity and few cases have been reported in the literature. Furthermore, the majority of these reports concern previous spine surgery or stress-related activities. Here, the authors report ankylosing spondylitis as a new cause of bilateral pedicle stress fractures accompanying spondylolysis. The reported case adds to the literature on bilateral pedicle stress fracture and spondylolysis by documenting that ankylosing spondylitis is another cause of this condition.

Objectives The purpose of this study is to assess the effect of korean medicinal admission treatment for degenerative lumbar diseases with spondylolysis and analyze their radiological findings. Methods This study was performed on 25 cases' medical records of spondylolysis patients with both X-rays and MRI images. Their general characteristics, morphologies of intervertebral discs, grades of spondylolisthesis, grades of intervertebral foraminal stenosis were analyzed. The efficacy of treatment was evaluated by numeric pain rating scale (NPRS) changes and statistically assessed by paired t-test using program R Studio. Results After admission treatment, NPRS scores significantly decreased from 6.76±2.07 to 2.38±1.22 (p<0.01). Spondylolysis was associated with degenerative disc change and intervertebral foraminal stenosis at the same or adjacent vertebral level. In spondylolisthesis cases (76%), forward slippage occurred at the same level of spondylolysis in every case. Conclusions Spondylolysis could play a key role in the lumbar degenerative mechanism and korean medicinal admission treatment is effective on pain relief of degenerative lumbar diseases with spondylolysis.

Spondylolysis, also known as stress injury of pars interarticularis, is a common cause of back pain in athletes, particularly children and young adults. Repeated minor traumas during flexion and extension of the spine are thought to result in bony failure due to excessive bone resorption. These lesions are common in the low back, with the majority found at the L5 vertebra. In the majority of cases of spondylolysis, non-operative treatments are recommended, such as NSAIDs, physiotherapy and bracing. Only if symptoms do not respond to conservative treatments should surgical intervention be considered. Recently, pars interarticularis injections for diagnostic and therapeutic purposes have been found to allow significant pain relief from spondylolysis for long periods. Here, the case of a 57-year-old man with spondylolysis, who suffered from back pain, which was not relieved by an epidural steroid injection, but in whom pars interarticularis injections of local anesthetic and steroid induced complete transient pain relief, following by moderate long-term relief, is presented.

Although most authors regard contralateral pedicular fracture with unilateral spondylolysis as an unstable condition and recommend surgical management when immobilization fails in promoting bony healing of the fracture, few researchers have investigated the natural history of pedicle fracture or the causal relationship between symptoms and the fracture. In addition, there are no detailed guidelines that address the management of this disease. We report a rare case of contralateral pedicular fracture associated with unilateral spondylolysis at the L5 level which was successfully treated by rehabilitation with activity modification.

Spondylolysis and spondylolisthesis are two conditions that directly involve changes in the vertebra. Spondylolysis is defined as a defect in the pars interarticularis, the region of the lamina between the superior and inferior articular facets. Progression of the defect can result in spondylolisthesis, which is defined as a subluxation or 'slippage' of two adjacent vertebrae. In the low back it occurs most commonly at the lumbosacral level; next in frequency is spondylolisthesis of the fourth lumbar vertebra on the fifth. To provide the reader with information about the aetiology and anatomical consideration of spondylolysis and spondylolisthesis type. Spondylolisthesis has recently been classified by Wiltse and others into five types based on the suspected aetiology; dysplastic, isthmic, degenerative, posttraumatic, pathologic and postsurgical. Of these five types, isthmic spondylolisthesi and degenerative spondylolisthesis, both of which are frequently associated with low back and lower limb pain.

Purpose : The aim of this study is to consider degenerative spine disease theoretically and compare plain radiography which is a basic study for low back pain with MRI in cases of degenerative lumbar spine disease to find out whether the abnormalities agree with each other. Methods : In 4 cases of lumbar degenerative disease, we studied the relation of the abnormalities such as disc space narrowing, spinal space narrowing, loss of lordosis and osteophytes on plain radiography with those on MRI of HIVD, spinal stenosis and spondylolisthesis. Results : Many abnormalities such as disc space narrowing, spinal space narrowing, loss of lordosis, osteophytes and change of cortex & bone marrow on plain radiography suggest HIVD, spinal stenosis, spondylolysis or spondylolisthesis on MRI. Conclusion : For low back pain patients, plain radiography is a basic study in diagnosis of HIVD, spinal stenosis, spondylolysis or spondylolisthesis but MRI or CT scan is necessary to develop(build) a treatment plan like an operation.

Abnormalities of the posterior arch, including congenitally absent cervical pedicle and cervical spondylolysis, are rare entities that are usually found incidentally on neck radiographs. It is important to recognize these characteristic radiological features because their radiographic appearance may cause them to be confused with more serious entities such as fractures, locked facets, and tumor-induced bony erosions. Also, it is important to distinguish these abnormalities from similar pathologies to prevent the use of inappropriate treatment We report the relevant clinical and radiological findings seen in three cases of posterior arch defect after trauma with review of pertinent literature.

Osteochondromas are common, benign tumors in the long bones, but osteochondromas are rare in the vertebrae. Most vertebral osteochondromas arise from the cervical or upper thoracic spine. However, lumbar osteochondromas have rarely been reported. In this report, a rare case of a lumbar osteochondroma arising from the spondylolytic L3 lamina in a 57-year-old woman is presented. She also had a ruptured disc and lumbar canal stenosis at L4-5-S1. The osteochondroma was completely removed and a posterior lumbar interbody fusion and instrumentation were performed. Considering the rarity of osteochondromas in the lumbar vertebrae, especially the L3 vertebra, it is possible that the pre-existing lumbar spondylolysis or spondylolisthesis was one of the factors affecting the occurrence or progression of the osteochondroma.
