Vascular Injury in Posterior Lumbar Spinal Surgery / 대한정형외과학회잡지

Vascular complications are uncommon, but it may pose a serious problem in posterior spinal surgery. Vascular injury during lumbar spinal surgery should be suspected if symptoms of circulatory instability are noted. If vascular injury is suspected, a contrast enhanced computed tomography should be checked and proper management, i.e., interventional treatment or surgery should be performed. To date, there have only been a few reports regarding vascular injuries during posterior lumbar spinal surgery. Clinicians should pay attention to signs of vascular injury during posterior spinal surgery, and accordingly, promptly perform treatment. In two patients with retroperitoneal hemorrhage, extravasation of the common iliac arteries was successfully repaired. One patient with pseudoaneurysm was treated by stent placement.

Validity of the Thoracolumbar Injury Classification System for Thoracolumbar Spine Injuries

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the validity of the thoracolumbar injury classification system (TLICS) when making treatment decisions in a group of thoracolumbar fracture patients. SUMMARY OF LITERATURE REVIEW: Few studies have evaluated the validity of the TLICS in consecutively treated patients, although many have evaluated the application of the TLICS to thoracolumbar injuries. MATERIALS AND METHODS: A retrospective study was performed among the 230 patients who were treated from 2003 to 2015 in our hospital for thoracolumbar injuries. Evaluations were made of clinical outcomes and radiologic results, and each case was analysed and scored according to the American Spinal Injury Association scale, the Magerl/AO classification, and the TLICS classification by 2 spinal surgeons. RESULTS: Of the 230 patients, 116 (50.4%) received conservative treatment and 114 (49.6%) received surgical treatment. Of the 116 patients who received conservative treatment, 112 (96.6%) were treated according to the TLICS guidelines. Conservative treatment failed for 2 of the 4 patients (1.7%) whose treatment did not correspond with TLICS, and they required surgical treatment. Of the 114 patients who underwent surgical treatment, in 87 (76.3%) the treatment corresponded to the TLICS guidelines. CONCLUSIONS: The TLICS classification showed high validity for the conservative treatment of thoracolumbar injuries.

Anatomic Characteristics of the Distal Femur and the Proximal Tibia in Koreans Undergoing Total Knee Arthroplasty / 대한정형외과학회잡지

PURPOSE: In this study, we examined the anatomic characteristics of the distal femur and the proximal tibia to determine if there were significant differences between male and female patients. MATERIALS AND METHODS: Seventy six patients (50 of female, 26 of male) who were treated by total knee arthroplasty using ROBODOC(R), were included. The anteroposterior and mediolateral length of the distal femur and proximal tibia were checked using the ORTHODOC program. RESULTS: The mean sizes of the distal femur and proximal tibia of female knees were slightly smaller than those of male knees. Statistically significant differences were observed between the two groups (p0.05 for all). CONCLUSION: The anteroposterior to mediolateral ratio was similar in the distal femur and proximal tibia of Korean females.
