RESUMEN
Extensor muscle strengthening exercises with counterforce braces (EX) is a conventional conservative treatment for lateral epicondylitis (LE) of the elbow. In addition, polydeoxyribonucleotide (PDRN) or extracorporeal shockwave therapy (ESWT) has been recently used for LE. Methods: Sixty-three patients with chronic LE participated in this study and randomly allocated in three groups (G1: EX, G2: EX+PDRN injection, and G3: EX+ESWT). All of the three groups were taught to perform EX at the first out-patient department (OPD) visit. Group 2 was injected with 3 mL PDRN (5.625 mg/3 mL), while group 3 received ESWT at the first OPD visit. Visual analog scale pain score, Mayo elbow performance score (MEPS), and ultrasonographic examination were checked before, 6 weeks, and 12 weeks after the treatments. Results: Overall functional scores and ultrasonographic findings in all three groups improved after treatment. The mean MEPS in group 2 improved more than groups 1 and 3 at 6 weeks (G1, 56.9>62.4; G2, 54.3>65.0; G3, 55.7>62.6), and more than group 1 at 12 weeks (G1, 56.9>67.9; G2, 54.3>73.6). The mean common extensor tendon depth (CETD) on ultrasonography in group 2 increased more than groups 1 and 3 at 6 and 12 weeks (6 weeks: G1, 0.385>0.386; G2, 0.332>0.392; G3, 0.334>0.357; 12 weeks: G1, 0.385>0.409; G2, 0.332>0.438; G3, 0.334>0.405 [cm]). Conclusions: PDRN injections combined with EX exhibited a greater improvement in mean MEPS and mean CETD compared to EX only or EX combined with ESWT for LE within the 12 weeks follow-up.
RESUMEN
OBJECTIVE: To illustrate the technique of single-stage posterior subtotal corpectomy and circumferential reconstruction for the treatment of unstable thoracolumbar burst fractures and to evaluate the radiographical and clinical outcomes of patients treated using this technique. METHODS: 16 consecutive patients with unstable thoracolumbar burst fractures were treated with single-stage posterior subtotal corpectomy and circumferential reconstruction. The mean patient age was 54.8 years. The mean follower up period was 25 months. Five patients suffered from T12 fractures, 10 from L1, 1 from L2. The segmental kyphosis, neurologic status, visual analogue scale for back pain was evaluated before surgery and at follow up. RESULTS: The segmental kyphotic angle improved from 18.5 degrees before surgery to -9.2 degrees at the last follow up. The mean correction angle was 28.9 degrees. The mean surgical time was 255 minutes, and a mean intraoperative blood loss was 1073 mL. Intraoperative complications included two dural tears, and a superficial wound infection. There were no other severe complications. The mean visual analog scale of back pain decreased from a mean value of 6.6 to 2 at the last follow up. CONCLUSION: The single-stage posterior subtotal corpectomy and circumferential reconstruction achieved satisfactory kyphosis correction with direct visualization of the circumferentially decompressed spinal cord, as well as good fusion with less blood loss and complications. It is a safe and reliable surgical treatment option for unstable thoracolumbar burst fractures.

PURPOSE: During the recent decades, the age at menarche continued to decline in Korea and worldwide. Prior studies have suggested that early menarche may increase the risk of various social, psychological, and physical health problems in young adolescent girls, but little is known about the determinants associated with early menarche. The purpose of this study is to evaluate independent determinants of early menarche among 5th~6th female graders in South Korea. METHODS: Our analysis was conducted in 95 menarcheal girls and 95 age-matched pre-menarcheal girls residing in Daegu, South Korea. Demographic and lifestyle characteristics were collected using survey questionnaires for children and parents. Dietary information was assessed by 2 day~24 hour food records and survey questionnaires, which were completed by both children and their parents. Anthropometric data were obtained from the student health check-ups at the school. RESULTS: A multiple logistic regression analysis using a conditional likelihood method was performed for simultaneous evaluation of several risk factors. There were significant differences in that higher proportion of obesity (OR, odds ratio = 5.60, 95% CI, confidence interval = 1.34~23.42), shorter sleep duration (OR = 0.45, 95% CI = 0.23~0.87), and younger mother's age at menarche (OR = 0.64, 95% CI = 0.44~0.93) were observed in the menarcheal group compared to the premenarcheal group. CONCLUSION: These findings indicate a possible association of sleep duration, mother's menarcheal age, and obesity with age at menarche. A well-planned, prospective cohort study is warranted to examine causal relationship.

OBJECTIVE: To present the incidence and management of dural tears and cerebrospinal fluid leakage during corrective osteotomy [Pedicle Subtraction Osteotomy (PSO) or Smith-Petersen Osteotomy (SPO)] for ankylosing spondylitis with kyphotic deformity. METHODS: A retrospective study was performed for ankylosing spondylitis patients with fixed sagittal imbalance, who had undergone corrective osteotomy (PSO or SPO) at lumbar level. 87 patients were included in this study. 55 patients underwent PSO, 32 patients underwent SPO. The mean age of the patients at the time of surgery was 41.7 years (21-70 years). Of the 87 patients, 15 patients had intraoperative dural tears. RESULTS: The overall incidence of dural tears was 17.2%. The incidence of dural tears during PSO was 20.0%, SPO was 12.5%. There was significant difference in the incidence of dural tears based on surgical procedures (PSO vs. SPO) (p<0.05). The dural tears ranged in size from 12 to 221 mm2. A nine of 15 patients had the relatively small dural tears, underwent direct repair via watertight closure. The remaining 6 patients had the large dural tears, consequently direct repair was impossible. The large dural tears were repaired with an on-lay graft of muscle, fascia or fat harvested from the adjacent operation site. All patients had a successful repair with no patient requiring reoperation for the cerebrospinal fluid leak. CONCLUSION: The overall incidence of dural tears during PSO or SPO for ankylosing spondylitis with kyphotic deformity was 17.2%. The risk factor of dural tears was complexity of surgery. All dural tears were repaired primarily using direct suture, muscle, fascia or fat graft.

Charcot spine is a progressive and destructive process that affects the vertebral bodies, intervertebral discs, and posterior facets. It is the result from repetitive microtrauma in patients who have decreased joint protective mechanisms due to loss of deep pain and proprioceptive sensation, typically because of spinal cord injury. The objective of the study is to report an unusual case of Charcot spine, as a late complication of traumatic spinal cord injury, treated by a circumferential arthrodesis performed with a single staged posterolateral costotransversectomy approach.

Multiple rice body formation is a complication of chronic bursitis frequently associated with seronegative rheumatoid arthritis or tuberculosis. It resembles synovial chondromatosis on imaging and clinically. We report on a pathologically diagnosed multiple rice body formation in subacromial and subdeltoid bursitis in a 44-year-old man who was treated by surgical removal and bursectomy. At 16 months after the removal, range of motion of affected shoulder was normal. No evidence of recurrence of rice body in plain X-ray and ultrasonography. Multiple rice body formed in chronic subacromial and subdeltoid bursitis could be treated with surgical removal and bursectomy successfully.

OBJECTIVE: To present the accuracy and safety of cervical pedicle screw insertion using the technique with direct exposure of the pedicle by laminoforaminotomy. METHODS: We retrospectively reviewed 12 consecutive patients. A total of 104 subaxial cervical pedicle screws in 12 patients had been inserted. We also assessed the clinical and radiological outcomes and analyzed the direction and grade of pedicle perforation (grade 0: no perforation, 1: 50% of screw diameter) on the postoperative vascular-enhanced computed tomography scans. Grade 2 and 3 were considered as incorrect position. RESULTS: The correct position was found in 95 screws (91.3%); grade 0-75 screws, grade 1-20 screws and the incorrect position in 9 screws (8.7%); grade 2-6 screws, grade 3-3 screws. There was no neurovascular complication related with cervical pedicle screw insertion. CONCLUSION: This technique (technique with direct exposure of the pedicle by laminoforaminotomy) could be considered relatively safe and easy method to insert cervical pedicle screw.

BACKGROUND: To report the results of an arthroscopic percutaneous repair technique for partial-thickness tears of the anterosuperior cuff combined with a biceps lesion. METHODS: The inclusion criteria were evidence of the upper subscapularis tendon tear and an articular side partial-thickness tear of the supraspinatus tendon, degeneration of the biceps long head or degenerative superior labrum anterior-posterior, above lesions treated by arthroscopic percutaneous repair, and follow-up duration > 24 months after the operation. American Shoulder and Elbow Surgeons (ASES) score, constant score, the pain level on a visual analogue scale, ranges of motion and strength were assessed. RESULTS: The mean (+/- standard deviation) age of the 20 enrolled patients was 56.0 +/- 7.7 years. The forward flexion strength increased from 26.3 +/- 6.7 Nm preoperatively to 38.9 +/- 5.1 Nm at final follow-up. External and internal rotation strength was also significantly increased (14.2 +/- 1.7 to 19.1 +/- 3.03 Nm, 12.3 +/- 3.2 to 18.1 +/- 2.8 Nm, respectively). Significant improvement was observed in ASES and constant scores at 3 months, 1 year and the time of final follow-up when compared with preoperative scores (p < 0.001). The mean subjective shoulder value was 86% (range, 78% to 97%). CONCLUSIONS: The implementation of complete rotator cuff repair with concomitant tenodesis of the biceps long head using arthroscopic percutaneous repair achieved full recovery of normal rotator cuff function, maximum therapeutic efficacy, and patient satisfaction.

There are few reported cases of flexor pollicis longus tendon (FPL) rupture complicating a closed distal radius fracture. We report a case of FPL tendon rupture complicating a closed distal radius fracture. A 24-year-old male presented with a severe right wrist pain. He had a closed distal radius fracture that was treated by closed manual reduction. Three days later, he complained forearm pain and limitation of thumb motion. The physical examination revealed loss of active interphalangeal joint flexion of thumb. He was taken to the operating room. Intraoperatively, the FPL was found to be discontinuous at the level of the radius fracture site. The FPL was repaired by a modified Kessler technique, and the fracture was repaired with a volar plate. Clinicians must be cautious in possibility of tendon injury complicating a closed distal radius fracture and assessing patients with distal radius fracture following closed reduction.

RESUMEN
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.

The present study demonstrates the effect of fibrates, agonists of PPARalpha on cytokines-induced proliferation in primary cultured astrocytes. Alone or combination treatment with cytokines, such as IL-1beta (10 ng/ml), IFNgamma (10 ng/ml), and TNF-alpha (10 ng/ml) cause a significant increase of cell proliferation in a time-dependent manner. Treatment of astrocytes with bezafibrate and fenofibrate (0, 5, and 10 micrometer) reduced the IFNgamma and IL-1beta-induced cell proliferation in a dose-dependent manner. To address the involvement of IL-6 on the IFNgamma and IL-1beta-induced cell proliferation, released IL-6 level was measured. IFNgamma and IL-1beta cause an increase of released IL-6 protein level in a time-dependent manner. Furthermore, pretreatment with IL-6 antibody (0, 0.1, 1, 2.5, and 5 ng/ml) dose-dependently inhibited the IFNgamma and IL-1beta-induced cell proliferation. However, bezafibrate and fenofibrate did not affect increased mRNA and protein levels of IL-6 in IFNgamma and IL-1beta-stimulated astrocytes. Taken together, these results clearly suggest that activation of PPARalpha attenuates the IFNgamma and IL-1beta-induced cell proliferation through IL-6 independent pathway.

PURPOSE: To report the loss of correction of a sagittal imbalance and the clinical outcomes after a corrective osteotomy for lumbar degenerative kyphosis. MATERIALS AND METHODS: This study analyzed the radiological parameters, surgical techniques, and clinical outcomes of 23 patients, who underwent corrective osteotomy for lumbar degenerative kyphosis. The patients were divided into groups I (>5 cm loss of correction of sagittal imblance, 12 patients) and II (3.5 out of 5, 11 patients) was compared with group B (low satisfaction score group <3.5 out of 5, 12 patients). RESULTS: The sagittal imbalance was corrected by performing a Smith-Petersen osteotomy (SPO) in 11 cases and Pedicle subtraction osteotomy (PSO) in 12. The mean preoperative sagittal imbalance was improved from 26.4 cm to 4.05 cm, postoperatively, and 11.2 cm at the last follow up. The mean loss of correction was 11.2 cm in group I and 2.3 cm in group II. The mean satisfaction score was 4.56 in group A and 2.18 in group B. The presence of an old compression fracture was found to be related to the loss of correction, and the preoperative symptomatic spinal stenosis was related to poor clinical outcomes. CONCLUSION: After mean 45 month follow up, the mean loss of sagittal correction was 38.3%, which mainly occurred at the proximal unfused segment. The clinical success rate was 45.5%, regardless of the loss of sagittal balance correction.

To our knowledge, there are no reported cases of rectal fistula complicating spondylodiscitis. We report the first case of a rectal fistula communicating with the site of postoperative recurrent spondylodiscitis. A-59-year-old female had recurrent spondylodiscitis after an open discectomy for L5-S1 eight years earlier. She underwent three operations including two anterior lumbar interbody fusion procedures after an open discectomy. Radiographic studies revealed severe bony destruction with abscess collection within the L5-S1 intervertebral disc space with fistula formation into the rectum. The fistula was confirmed by a Barium enema colon study and sigmoidscopy. The patient underwent a staged operation consisting of a rectosigmoid colon resection, anterior interbody fusion and posterior instrumented fusion. Rectum related complications were suspected in this case of recurrent spondylodiscitis.

STUDY DESIGN: A prospective study OBJECTIVES: We wanted to assess the clinical outcomes of posterior dynamic stabilization with selective wide decompression for treating multilevel lumbar stenosis in old age. SUMMARY OF THE LITERATURE REVIEW: Deciding on the segments to be operated on is challenging problem for old age patients with multilevel lumbar stenosis. There have been no reports on posterior dynamic stabilization with selective wide decompression for treating multilevel lumbar stenosis. MATERIALS AND METHODS: We evaluated 18 patients who underwent posterior dynamic stabilization with selective decompression for multilevel disc degeneration and spinal stenosis. The mean age was 70.2 years and mean follow-up was 15.1 months. We evaluated the segmental angle, the range of motion (ROM) and pedicle screw loosening. The clinical results were evaluated according to the operative time, blood loss, the visual analogue scale (VAS) for the back pain and leg pain and and the Oswestry disability index (ODI). RESULTS: The mean number of operated segments was 2.16. The lordosis of the lumbar and operated segments showed no significant difference. However, the ROM of the total lumbar spine and the operation segment was significantly decreased from 36.8 to 24.3 and 22.9 to 13.1, respectively. The ROM for the adjacent segment did not show a significant difference. A radiolucent line around the pedicle screw appeared at 22 screws (19.3%) out of a total 114 screws. The VAS for back and leg pain were improved from 7.5 and 8.6 to 2.3 and 2.1, respectively. The ODI was improved from 41.5 to 13.4. CONCLUSIONS: The initial clinical outcomes were favorable after posterior dynamic stabilization with selective decompression. This procedure could be considered to be a useful option for treating multilevel stenosis in old age patients.

PURPOSE: Anterior cervical fusion with a tricortical iliac bone graft is a well established procedure for treating degenerative cervical spine disease. An interbody cage has been used to prevent donor site morbidity but there are few reports on the clinical and radiological outcome. MATERIALS AND METHODS: Thirty eight patients, who underwent single level ACDF with PEEK interbody Solis(R)cage (Stryker spine, South Allendale, NJ, USA), were enrolled in this study. This study evaluated Odom's criteria and visual analogue scale (VAS) for the neck, arm and donor site pain, and the radiological findings, including the disk height, cage subsidence, and sagittal alignment of cervical spine. RESULTS: The mean disk height loss was 1.1 mm during the follow up period. Case subsidence >2 mm developed in 17 cases (44.7%). The mean subsidence of this group was 3.09 mm. The bone union rate was 95% at 12 weeks. There was no significant change in the sagittal alignment of the cervical spine. The VAS for neck, arm, and donor site pain improved all cases. Only 9 patients complained of mild discomfort at the donor site CONCLUSION: Single-level ACDF using PEEK interbody cage has a lack of donor site morbidity, excellent clinical outcomes and bone union. However, more study of the factors related to postoperative cage subsidence will be needed.

Purpose: We analyzed the clinical features, management and outcome of small bowel intussusception in children compared with ileocolic intussusception. Methods: We retrospectively reviewed the records of 210 children with documented intussusception, in whom intussusception was initially diagnosed by ultrasonography during the four-year period of 2002 to 2005. Results: A total of 191 children were diagnosed with ileocolic intussusception and 19 were diagnosed with small bowel intussusception. Children with small bowel intussusception were older than children with ileocolic intussusception (P<0.05). In comparison to patients with ileocolic intussusception the characteristic presenting symptoms-such as currant jelly stool and palpable mass-were rarely observed in patients with small bowel intussusception. In ileocolic intussusception, air reduction (92.2%), or surgical reduction (7.3%) was performed; however, in small bowel intussusception, spontaneous reduction (78.9%) was observed and no surgical reduction was required in our study. Conclusion: Conservative management with close observation and follow-up sonographic evaluation rather than an immediate operation is recommended for children with small bowel intussusception.

Crossed renal ectopia is a congenital malformation in which both kidneys lie on the same side of the spine, usually side by side longitudinally. More often on the right side. Fusion of the two renal units is eight times more common than nonfusion. Although crossed renal ectopia is uncommon, this unusual entity must be considered in an infant when cystic mass in the abdomen or pelvis paticularly if no kidney can be found on the opposite side. In many cases of crossed fused ectopia with multicystic dysplastic kidney(MCDK), the diagnosis can be strongly suspected from the sonogram, and no other studies may be necessary. However, both intravenous urography and isotope renography is useful to assess the function of the crossed kidney. Crossed renal ectopia and MCDKs are associated with a greater incidence of ureteropelvic junction obstruction and reflux. So, screening voiding cystourethrography should be performed. Very few studies of MCDK in the setting of crossed fused ectopia have been reported. We have experienced a 3-year-old boy with crossed fused renal ectopia with multicystic dysplasia.

PURPOSE: Transcatheter closure of patent foramen ovale (PFO), atrial septal defect (ASD) and patent ductus arteriosus (PDA) is a new and less traumatic technique than open heart surgery. One of the more popular occluding devices is the Amplatzer(R) septal occluder which is made of nitinol. The present study was undertaken to evaluate the safety and release of nickel after implantation of Amplatzer(R) occluder in patients with PFO, ASD and PDA. METHODS: Random blood samples were obtained from 25 patients with Amplatzer(R) PFO, ASD, PDA occluder during 4-year and 7-month post closure period. The nickel content in the specimens was determined using atomic absorption spectrometer. RESULTS: All patients showed satisfactory clinical improvements and there was no echocardiographic evidence of complications. During the post closure, concentrations of nickel in serum were within normal range with values 0.2 ug/dL. CONCLUSION: Nickel seems to be released from Amplatzer(R) occluder. The dissolusion of nickel from Amplatzer(R) occluder is minimal and systemic rise in serum levels of nickel are within normal range. However, further studies are needed to evaluate biological effects in patients with nickel hypersensitivity.

The dystrophic type of neurofibromatosis is a well-known bizarre deformity of the spine. There has been little literature about spontaneous vertebral column dislocation in the thoracic spine with progressive neurological symptoms. The authors present a case of thoracic spine dislocation vertically and transversely with intact posterior elements. A 35-year-old woman had stooping and back pain for five years. She developed motor weakness of both lower extremities three months ago. Plain X-ray and three-dimensional CT scans showed dislocation between T5 and T6 vertebrae, that were which was translated transversely and vertically with severe resorption of vertebral pedicles of T5 and T6. After skeletal traction, motor weakness was improved. And we performed two-staged anterior and posterior fusion to stabilize severe kyphoscoliosis. The patient was improved neurologically with free ambulation state at 24-month follow-up. Combined anterior and posterior fusion was an effective method for the treatment spontaneous vertebral column dislocation in the thoracic spine with progressive neurological symptoms.
