AbstractAbstract PDF
Other than gunshot injuries, sacral penetrating injuries with a foreign body exiting to the other side are extremely rare. We encountered a case of sacral injury in which a long metallic pipe penetrated from the anus into the lower back of a patient. Since the pelvis contains various organs, management of a penetrating injury requires multidisciplinary treatment involving several medical specialties. Due to the infrequency of this type of injury, there are no definitive guidelines for effective management. We described our experience surgically treating a sacral penetrating injury and conducted a literature review. On this basis, we suggest a surgical strategy for treating this type of injury.

AbstractAbstract PDF
The most common cause of foot drop is lumbar degenerative disc herniation, particularly at L4/5. We present a rare case of spinal cord injury accompanied by a thoracolumbar lesion that presented with bilateral foot drop. A 69-year-old male patient presented with sudden-onset severe bilateral leg pain and bilateral foot drop. Radiologic findings revealed T12 spondylitis compressing the conus medullaris. He had undergone vertebroplasty for a T12 compression fracture after a fall 6 months before. A physical examination showed bilateral foot drop, paresthesia of both L5 dermatomes, increased deep tendon reflex, and a positive Babinski sign. An acute bilateral L5 root lesion and a conus medullaris lesion were suspected based on electromyography. A surgical procedure was done for decompression and reconstruction. After the operation, bilateral lower extremity muscle strength recovered to a good grade from the trace grade, and the patient could walk without a cane. The current case is a very rare report of bilateral foot drop associated with T12 infectious spondylitis after vertebroplasty. It is essential to keep in mind that lesions of the thoracolumbar junction can cause atypical neurological symptoms. Furthermore, understanding the conus medullaris and nerve root anatomy at the T12–L1 level will be helpful for treating patients with atypical neurological symptoms.

AbstractAbstract PDF

The purpose of this study was to determine the incidence and characteristics of associated injuries in patients with spine trauma.


Data of 3,920 consecutive patients admitted to a regional trauma center during a 3-year period were analyzed retrospectively.


Of the 3,920 patients who were admitted to the trauma center during the 3-year study period, 389 (9.9%) had major spinal injuries. Among these 389 patients, 303 (77.9%) had associated injuries outside the spine. The most common body region of associated injuries was the extremities or pelvis (194 cases, 49.4%), followed by the chest (154 cases, 39.6%) and face (127 cases, 32.6%). Of these 303 patients, 149 (64%) had associated injuries that required surgical treatment such as laparotomy or internal fixation. Associated injuries were more common in patients with lumbar injuries (93.3%) or multiple spinal injuries (100%) than in those with lower cervical injuries (67.4%). There was a significant correlation between the location of the spinal injury and the body region of the associated injury. However, distant associated injuries were also common.


Associated injuries were very common in spinal injury patients. Based on demographic groups, the trauma mechanism, and the location of spinal injury, an associated injury should be suspected until proven otherwise. Using a multidisciplinary and integrated approach to treat trauma victims is of the paramount importance.

AbstractAbstract PDF
The aim of this study was to estimate the seropositive prevalence of blood-borne infection in neurotrauma patients who underwent emergent surgical intervention, especially patients with hepatitis B virus (HBV), hepatitis C virus (HCV), syphilis and human immunodefIciency virus (HIV).
A retrospective review identified 559 patients with traumatic brain injury and spinal trauma who underwent emergent surgery between 2007 and 2014. We reviewed the medical records and extracted data, including age, sex, location of lesion, result of serologic tests, time interval of admission and surgery after presenting to emergency room. Serologic tests for HBV, HCV, syphilis and HIV were performed and analyzed to determine whether the seropositive results were confirmed by the surgeon before surgery.
The majority of the patients were male (74.6%), and the mean age was 55.4+/-20.2 years. Most patients underwent surgery due to traumatic brain injury (90.0%). Fifty-three patients (10.0%) showed a positive result on at least one serologic test. Seropositive rates according to pathogens were 0.5% for syphilis, 5.2% for HBV and 3.9% for HCV. No positive results were noted on the serologic tests for HIV. HBV in patients with spinal cord injury and age from 40 to 49 years were associated with high serologic positive rate, and that result was statistically significant. However, no statistically significant differences were found in the other variables. Serologic results could not confirmed before surgery in the majority of the cases (62.1%), and 10.4% of these patients showed seropositive results.
The results of this study emphasize the importance of taking precautions and conducting rapid serologic testing in preventing the occupational transmission of blood-borne viruses to health-care workers.
