Purpose: To determine the therapeutic effectiveness of ultrasound-guided medial branch block (MBB) for the herniated lumbar disc patients who did not relieve their symptoms after percutaneous epidural neuroplasty (PEN). Materials and Methods: From August 2011 to February 2013, 559 patients with herniated lumbar disc have undergone PEN. Among them, ultrasound-guided MBBs were performed for the patients who had sustained low back pain and refered pain to lower extremities. Eighty eight patients were followed at 1 month and 39 patients could be followed at 6 month. All procedures have been performed by the one operator, and 23 G, 10 cm needle was placed and 0.5% lidocaine was injected under ultrasound guide. To target medial branches from L1 to L5, the groove at the root of transverse process and the base of superior articular process has been identified on transverse scan. Patients were evaluated by Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) at each follow-up. Significant pain relief was described as a 50% or more reduction in VAS and significant improvement in function was described as at least a 40% reduction in ODI. Results: VAS showed that preprocedure pain ($7.35{\pm}1.68$; $mean{\pm}SD$) significantly decreased 1 month after block ($3.36{\pm}2.98$) and 6 month ($3.05{\pm}2.27$) (p<0.05). ODI also showed that preprocedure score ($32.82{\pm}8.77$) significantly decreased at 1 month ($15.14{\pm}14.01$) and 6 month ($12.97{\pm}8.82$) (p<0.05). Significant pain relief was observed in 64.49% at 1 month and 64.10% at 6 month. Significant functional improvement in 59.81% at 1 month and 61.54% at 6 month. Conclusion: Ultrasound-guided medial branch block may sufficiently treat the facet problems secondary from disc disease.

This review was described to investigate the feasibility of using ultrasound as an image tool for interventions of lumbar spine. This article will first provide an overview of lumbosacral spine surface anatomy and sonoanatomy. A detailed understanding of anatomy is critical for interpretation of ultrasound and procedural performance at spine. Fluoroscopy is most commonly used in interventional spine procedures, but radiation exposure is the major concern when obtaining fluoroscopic images. Ultrasound is radiation-free, is easy to use, and can provide real-time images with high accuracy. Also this device can be used in virtually any clinical setting. Ultrasound guidance offers a reliable alternative to fluoroscopy or computed tomography for lumbar interventions and can be safely performed without radiation exposure.

Parachordoma is an extremely rare tumor that histologically resembles chordoma of axial skeleton but occurs in a peripheral site. It is considered an indolent neoplasm with potential for local recurrence. We present a case of soft tissue parachordoma at inguinal subcutaneous tissue which recurred 2 months after primary simple excision under local anesthesia and was performed revisional wide excision. Bone scan showed no other metastatic lesion. Immunohistochemical findings revealed tumor cells to be reactive to EMA, S-100 protein, vimentin and cytokeratin.

Traditionally, cervical interventions have been performed under fluoroscopy. But radiation exposure is the major concern when obtaining fluoroscopic images and even under real-time fluoroscopy with contrast media or CT guidance, some cases of serious spinal cord injuries, cerebellar and brain stem infarction have been reported by unintentional intra-arterial injections especially during the transforaminal root blocks. Recently, the use of ultrasound-guided cervical interventions have increased. Ultrasound offers visualization of soft tissues including major neurovascular structures and also allows to observe the spread of injectant materials around the target structure. Ultrasound is radiation free, easy to use and the image can be performed continuously while the injectant is visualized in real-time, increasing the precision of injection. Importantly, ultrasound allows visualization of major nerves and vessels and thus leads to improve safety of cervical interventions by decreasing the incidence of injury or injection into nearby vasculature. We therefore reviewed to investigate the feasibility of performing cervical interventions under real-time ultrasound guidance.

Purpose : To verify radiological changes of limb salvage operation using tumor prosthesis. Materials and Methods : Sixty-nine cases which used tumor prosthesis were reviewed. They have been followed up for average four years and nine months. We evaluated radiographs by ISOLS(International Symposium On Limb Salvage) radiological implants evaluation system immediate postoperatively, at postoperative 1 year and last follow-up. After converting 'excellent, good, fair, poor' to '4, 3, 2, 1' for stastical analysis, data were analyzed according to the use of cement, anatomical sites, diagnosis implant designs and age (<20 year vs. ${\geq}$20 year) using t-test and ANOVA. Results : The outcomes of cemented type prostheses were superior in remodelling and interface but inferior in anchorage. The scores of proximal femur and distal tibia were worse in bone remodelling. Osteosarcoma group had lower scores in anchorage and implant articular problem. There were no significant differences according to four different implant designs and age. Conclusion : In the intermediate term follow-up radiological evaluation, cemented type prosthesis were better in the aspects of bony resorption and osteolysis, and cementless one in anchorage. Distal femur and proximal tibia have higher scores in bony resorption, and osteosarcoma was worse tumor entity in anchorage and articular problem, and chemotherapy may be the cause.

요근 농양은 전통적으로는 수술적 배농술이 많이 시도되고 있으나 초음파 유도하 경피적 천자술이 효과적인 치료방법이 될 수 있다. 그러나 아직까지 초음파를 이용한 천자술의 유용성에 대해서는 잘 확립되어 있지 않다. 저자들은 진균성 요근 농양을 초음파 유도하 경피적 천자술로 치유하였던 증례를 경험하였기에 문헌 고찰과 함께 보고하고자 한다. 배농은 초음파 영상 하에서 침 천자술로써, 시술로 인한 합병증의 발생 없이 시행하였다. 배농 후 배양에서 Candida Albicans가 동정되었으며 두 번의 천자술과 적절한 항진균제 치료로써 성공적으로 치유할 수 있었다.

Purpose: Frequency of sesamoid bone on hallucal interphalangeal joint has been described to be low probability in orthopaedic and anatomical literature. We have, however, experienced two cases of interphalangeal joint dislocation giving difficulty to usual manipulative reduction because of presence of sesamoid bone recently. In order to ascertain existence of sesamoid bone on interphalangeal joint of hallux in Korean adults, radiological study have been performed with feet of patients Materials and Methods: Between May 2003 and October 2006, 974 patients with 1098 radiographs of feet which were reached skeletal maturity over 18-year-old were examined. Unilateral or bilateral anteroposterior, lateral and oblique radiographs were observed by one same person and presence was recorded if there was sesamoid in films. Distance of long and short axes were measured in lateral view and cases of two sesamoids in interphalangeal joint were recorded. Statistical differences between left and right side or between men and women were evaluated by chi-square test. Results: Frequency of sesamoid was 980 cases (89.3%) and no occurrence in 118 cases (10.7%). Two sesamoids were observed in 3 cases. Average distance of long axis was 4.9 mm (range, 0.5-11.4) and average distance of short axis was 3.5 mm (range, 0.3-9.3). Unilateral sesamoid was observed in 7 patients (5.6%), bilateral absence was 7 patients (5.6%) and bilateral sesamoids in 110 patients (88.8%) out of 124 patients who took bilateral feet radiographs. Men has less frequency than women significantly (p=0.014) while there was no significant difference in frequency according to side(p>0.05). Conclusion: Sesamoid bone was seen in 980 feet (89.3%) out of 1098 normal Korean radiological studies of feet. We report 3 cases of two seamoids which was extremely rarely reported in literature. Korean frequency is similar with Japanese, but much higher than Caucasians and black Africans.
