In this study, we present the difference in thoracic reposition sense in young people (24.00 ±2.20 years old) with and without habitual slouched posture in two target positions of half flexion and half extension. People with habitual slouched posture (n = 20; 11 men and 9 women) and people without slouched posture (n = 20; 10 men and 10 women) were recruited from three universities. Thoracic spine (T-spine) repositioning errors were measured in two target positions (half flexion and half extension). People with habitual slouched posture showed significantly higher thoracic repositioning error in the extension target position than did people without slouched posture (P<0.05). There was no difference in repositioning error in the flexion target position between the two groups (P>0.05). In conclusion, people with habitual slouched posture show lower T-spine repositioning sense in extension than do people without slouched posture. A rehabilitation program to treat habitual slouched posture, such as postural correction education, should be implemented for individuals with decreased position sense of the T-spine.

Unexpected postoperative changes, such as growth in rib hump, has been occasionally reported after corrective surgery for scoliosis. However there has been experimental data for explanation of these changes, nor the suggestion of optimal correction method. This numerical study was designed to investigate the main correlating elements in operative kinematics with post-operative changes of vertebral rotation and rib cage deformation in the corrective surgery of scoliosis. To develop a scoliotic spine model automatically, a special program for converting normal spine model to scoliotic spine model was developed. A mathematical finite element model of normal spine including rib cage, sternum, both clavicles, and pelvis was developed with anatomical details. The skeletal deformity of scoliosis was reconstructed, by mapping the X-ray images of a scoliosis into this three dimensional normal spine and rib cage model. The geometric mapping was performed by translating and rotating the spinal colume with the amount analyzed from the digitized 12 built-in coordinate axes in each vertebral image. By utilizing this program, problems generated in mapping procedure such as facet joint overlapping, vertebral body deformity could be automatically resolved.

Intracranial haemorrhages are rare but potentially life-threatening complications of spine surgery. Most reported cases involved subdural or cerebellar haemorrhages; supratentorial parenchymal bleeding is very uncommon. We report a 28-year-old woman who underwent resection of a thoracic Ewing's sarcoma, and developed fatal haemorrhages around her cerebral metastases during surgery. The clinical presentations, possible pathogenesis and potential preventive measures are discussed. Patients with disseminated metastases within the neural axis are at risks of intracranial complications during spine surgery. The presence of intracranial mass lesions should be considered as a relative contraindication to intradural spine surgery.

We here report a case of long-term fistula formation due to bullet retention for 30 years in the lumbar spine after a gunshot injury, and describe its treatment. A 62-year-old male visited our hospital due to pus-like discharge from his left flank. The discharge had been present for 30 years, since his recovery from an abdominal gunshot injury. A spine radiography showed radiopaque material in the body of the third lumbar vertebra. Foreign body was removed using an anterolateral retroperitoneal approach. The postoperative course was uneventful. The patient was discharged 7 days after the operation and was followed-up for 8 months, during which time, the fistula did not reoccur. A bullet retained long term in the vertebral body may cause obstinate osteomyelitis and fistula formation. A fistula caused by a foreign body in the spine can be effectively treated by surgical removal.

Aneurysmal bone cyst is a benign, highly vascular bony lesion of unknown origin that may present difficult diagnostic and therapeutic problems. It is usually located on long bones, but rarely on the spine. The lesion is usually treated successfully by curettage and bone grafting when it involves bones of the extremities, but there are special considerations in the management of the lesion when located on the spine. We report a case of aneurysmal bone cyst in on the 8th thoracic spine treated with surgical treatment.

Rhabdoid tumor of the kidney (RTK) is a rare malignancy in infancy. Central nervous system involvement in RTK is already known. However, solitary spinal metastasis in RTK has been hardly reported. The authors report a case of metastatic RTK to spine causing paraplegia in an 8-month-old girl. Since the patient was young, the diagnosis of spine metastasis was delayed until paraplegia was seen after radical nephrectomy. Thorough neurological examination should be performed for early diagnosis of spinal metastasis in young patients with RTK. If there are any abnormal signs in neurologic examination, magnetic resonance images of brain and spine are recommended.

The management of lower cervical fractures in patients with ankylosing spondylitis (AS) differs from normal cervical fractures. Patients with AS are highly susceptible to extensive neurologic injuries and spinal deformities after cervical fractures from even minor traumatic forces. These injuries are uniquely complex, require careful imaging assessment, and aggressive surgical management to optimize spinal stability and functional outcomes.

Core spine muscle are related are associated with trunk stability and play a main role for the prevention of low back pain. In this study, it was investigated the effect of spine stabilization exercise device on core spinal muscles using a musculoskeletal model The forward direction of the tilt mainly induced the activation of long and superficial back muscles and the backward affected the front muscles. It was shown that spine stabilization exercise device can induce significant core muscle exercise effect.

Ganglioneuroma (GN) is a rare benign tumor of neural crest origin usually found in the abdomen, but may occasionally present at uncommon sites including the cervical, lumbar, or sacral spine. However, GNs of thoracic spine are extremely rare. In this report, we describe a 12-year-old girl with giant GN in the thoracic spine, who underwent successful resection (T1-4 level) of the tumor. Histopathological examination confirmed the diagnosis. GN should be considered in the differential diagnosis of any paraspinal mass. A high index of suspicion and correlation of clinico-radiological findings is necessary in differentiating a large benign tumor from a malignant growth. Complete surgical excision is the treatment of choice; however tumor size and location need to be considered for the surgical approach (one-step or multiple surgeries). Close follow-up after surgery is mandatory.

Purpose: This study was conducted in order to examine the changes of muscle activitis of erector spine muscles and Gluteus maximus during the bridge exercise with adductor muscles. Method: After attaching the EMG device to the Gluteus maximus and erector spine muscles of the 100 healthy adult males in their 20s, applying the stabilizer pressure biofeedback device between the knees, the bridge movement was carried out 10 seconds. Result: During the exercise of the bridge movement, the muscular activities in erector spine and gluteus maximus were significantly different in ralation to the simultaneous contractive adductor muscles of the bridge(p<.05). Conclusion: Thus, the bridge exercise is carried out in conjunction with the simultaneous contraction of adductor muscles that suggests that the training are more effective in erector spine and gluteus maximus activities.
