OBJECTIVES: The purpose of this study was to determine the association between the bone mineral density (BMD) and severity of spinal osteoarthritis (spondylosis) in osteoporotic spinal compression fracture. METHODS: Fifty six patients were evaluated 66 cases had an osteoporotic thoracolumbar compression fracture between January 2008 and June 2010. The average patient age was 76.2 years (M/F : 8/48). Age and body mass index (BMI, kg/m2) were measured, and the BMD was performed using peripheral quantitative computed tomography (pQCT). Simple thoracolumbar (T-L) spine lateral radiography was evaluated for three criteria: presence of osteophytes, disc space narrowing and vertebral body sclerosis. The findings were graded 0 to 3 and analyzed statistically for a correlation with the BMD and fractured vertebrae. RESULTS: Acute compression fractures comprised of 15 cases and the most common site of acute fractures with old fractures was lumbar spine (L1; 30 cases, 45.4%). The average of BMI was 23.32 and BMD (T-score) was -4.47. Pearson's rho showed a positive association between the weight, height and the BMD (P < 0.01). In terms of the BMD versus spondylosis, there was a positive association with high score in the high order cortical bone. Compression fractures occurrence rate in the absent and present of spondylosis was 74.3% and 22.4%, and 69% occur in the spinal segmental with no bony spur with chi-square test (P < 0.01). CONCLUSION: In the present of spondylosis was high score of cortical BMD and low rate of compression fracture. Spondylosis could be one of a factor of the occurrence in acute and adjacent compression fracture after old fractures.

The risk of deep vein thrombosis (DVT) is well studied for some orthopedic surgery. However, the incidence of postoperative DVT is less well-defined in patients who have spinal surgery. In addition, there is insufficient evidence to suggest that screening patients before spinal surgery and to use of prophylactic method such as anticoagulants, compression stockings, and pneumatic compression device. We experienced a 78-year-old female patient of DVT after fusion operation with pedicular screws in T12 osteoporotic compression fracture. As risk of DVT after major spinal surgery is fairly low, it seems reasonable to consider prophylactic management after spinal surgery in old aged patients with difficult ambulation.

Superficial peroneal nerve entrapment is an uncommon compression neuropathy, and is frequently associated with a fascial defect and a muscle hernia. The standard treatment of that was the nerve decompression by complete or limited fasciotomy. But, we experienced a case of superficial peroneal nerve entrapment had satisfactory surgical outcome by fascial repair of peroneus muscle.

PURPOSE: The purpose of the study is to evaluate the effectiveness of selective nerve root block (SNRB) in advance to the patient who is going to undergo the operation for lumbar herniated intervertebral disc (HIVD). MATERIALS AND METHODS: 103 cases were selected from among SNRB conducted to the patients who had been diagnosed by this hospital to have lumbar HIVD from December 2004 to November 2005 and assigned for operations. The follow-up period was 10 months in average (2.5-30 months) and the average age was 35.5 years (19-72 years). Patients had been monitored by means of clinical records, interviews and telephone and features of symptoms and stage of nerve root compression were compared between the group of operated patients and that of the non-operated. RESULTS: As for stages of nerve root compression, 15 cases could be classified to belong to the 1st stage, 4 cases to the 2nd stage and 1 case to the 3rd stage. Among 42 cases for which operations were conducted because there was no improvement after SNRB. Divided by stages of nerve root compression, 13 cases belonged to the 1st stage, followed by 10 cases to the 2nd stage and 4 cases to the 3rd stage. No statistically significant difference turned out to exist the clinical results between 42 cases which underwent operations and 61 cases which experienced improvement after nerve root block. No significant difference, either, was confirmed from the statistical outcomes between SNRB group and operations. CONCLUSION: The preserving treatment using SNRB for the patients with lumbar HIVD seems to have positive clinical effects. Features of radiating pains or stages of nerve root compression, however, can't be regarded to be factors foretelling the treatment effects of SNRB.

PURPOSE: To compare and analyze the surgical procedure and clinical results of two-stage re-implantation using both articulating and static spacers at infected total knee arthroplasties(TKA). MATERIALS & METHODS: A total of 14 cases were selected for subject of this study in which patients had been diagnosed as infected TKA and had undergone two-stage re-implantation(7 using static spacers and remaining 7 using articulating spacers) from March 1999 to March 2006. RESULTS: In the group using static spacers, ROM improved from 70 degrees in average preoperatively to 98 degrees postoperatively. In the group using articulating spacers, ROM improved from 74 degrees to 105 degrees (p=0.532). HSS score showed an increase from 43 scores in average preoperatively to 81 postoperatively for static spacers and from 41 to 83 for articulating spacers(p=0.780). There was no significant difference in the hour spent for the 1st surgery. The 2nd operation time was shortened to 241 minutes in case of static spacers, and 208 minutes in articulating spacers. One case of relapse was reported with static spacers but none with articulating spacers. CONCLUSION: Two-stage re-implantation of infected TKA using both static and articulating spacers has been found to be effective ways of treatment, requiring, however, long term follow-ups.

Arthroscopic meniscectomy of the knee is generally a safe and effective procedure with a low rate of vascular complications. The authors encountered a case of a pseudoaneurysm of the lateral inferior genicular artery after arthroscopic partial meniscectomy of lateral meniscus. The pseudoaneurysm was treated successfully using transcatheter embolization. No recurrence of the hemarthrosis was observed in the patient after a follow-up of 2 years.

PURPOSE: We investigated the short term outcomes of isolated tibial polyethylene insert exchange after revision total knee arthroplasty. MATERIALS AND METHODS: We selected 18 cases from 17 patients among the 20 cases from 19 patients who took isolated tibial polyethylene insert exchange after mean 69 months-follow up of TKA, which was carried out from June 1991 to August 2003. Two cases were excluded on account of loss to follow-up. In all cases, isolated tibial polyethylene insert exchange was carried out from May 1998 to October 2008 in our institute and the mean follow-up period after operation was 48 (22-142) months. We evaluated the following clinical and radiologic aspects: range of motion, HSS score, average labor time, and BMI. Together, these factors were used in clinical evaluation while femorotibial angle and radiolucent line were used in radiologic evaluation. RESULTS: The average range of motion was 110.6 degrees and HSS score was 86.9 in follow up period. The average femorotibial angle was valgus 5.3degrees. The average labor time was 9.7 hours and BMI was 25.9. Although radiolucent line was found in 4 cases, there were all confirmed to be non progressive lesion less than 2 mm. Survival rate was 100% in Kaplan-Meier survival analysis. CONCLUSION: Selective isolated tibial polyethylene insert exchange can be the successful method for revision TKA in limited cases.

PURPOSE: This study evaluated the operability for disease of lumbar intervertebral disc (LID) of practitioners and pay doctors of orthopedic surgeons and neurosurgeons by examining their websites. MATERIALS AND METHODS: From March 2006 to April 2006, we searched the internet using the key words orthopedic surgery and neurosurgery, with NAVER as the portal site. There were 68 homepages of orthopedic hospitals and physician's offices (OHP) and 27 homepages of neurosurgical hospitals and physician's offices (NHP). Each homepage was visited in order to survey the operability for disease of an intervertebral disc and the number of board of orthopedists and neurosurgeons. Statistical analysis was carried out using a chi-square test. RESULTS: In 45.6% (31/68) of OHP and 85.2% (23/27) of NHP, the operation for LID was performed and there was significant difference (p<0.001). In 16.2% (11/68) of OHP, neurosurgeons employed by OHP performed the operation for spinal disorders. In 29.4% of OHP, the orthopedic surgeon performed the operation for LID. Orthopedists were employed in 51.9% of NHP. NHP were significantly higher than OHP in the cases in whom the orthopedists and neurosurgeons worked together in a single hospital (p<0.001). CONCLUSION: In 70% of OHP, surgery for LID was not performed. A survey about reasons for not performing operation for LID and improvement of that reasons should be carried out by the medical association.
