Purpose: To evaluate the characteristics and the risk factors of early onset subsequent vertebral compression fractures after percutaneous vertebroplasty. Materials and Methods: A total of 44 patients, who had a new subsequent vertebral fracture after percutaneous vertebroplasty for an osteoporotic vertebral compression fracture between January 2013 and December 2015, were recruited. The patients were divided into two groups according to the onset period of subsequent fracture. The number of patients who had a fracture within 3 months following vertebroplasty were 22 cases (Group A); after 3 months were 22 cases (Group B). Variables, including age, sex, bone mineral density (BMD), body mass index (BMI), preexisting vertebral compression fracture, location of the initial fracture, intradiscal cement leakage, injected cement volume, restoration of vertebral body height, and correction of kyphosis, in the two groups were analyzed and compared retrospectively. Results: The age, sex, BMD, BMI, preexisting vertebral compression fracture, location of the initial fracture, intradiscal cement leakage, and correction of kyphosis were similar in the two groups. Both a greater volume of bone cement injected and a greater degree of vertebral height restoration contributed significantly to the risk of fracture within 3 months. Conclusion: The cement volume and degree of height restoration are risk factors for early onset fracture at the adjacent vertebrae after percutaneous vertebroplasty and close attention is needed during the follow-up period.

Lumbar disc herniation in the adolescent is rare. The clinical features of adolescent lumbar disc herniation are typically different from those of adults. Many adolescent with that disease may be misdiagnosed as minor trauma, muscle sprain, tight hamstrings or scoliosis. Published series reiterate that adolescents, as opposed to adults, do not respond well to conservative treatment. In adolescent lumbar disc herniation with hamstring tightness, the neurologic defects are improved shortly after, discectomy, but the hamstring tightness continue and remain even after 1 year. Earlier discectomy and adjunct postsurgical conservative measures can provide a greater opportunity for correction and stabilization of scoliotic posture. We here report on a case of adolescent lumbar disc herniation that was misdiagnosed by knee injury during 2 years. After posterior partial discectomy, the hamstring tightness and scoliosis was disappeared without complication.

Purpose: We conducted this study to examine the clinical results of the proximal metatarsal wedge osteotomy using a single screw fixation and the distal soft tissue procedure in patients with moderate to severe hallux valgus deformity. Materials and Methods: Between February 2002 and February 2004, we performed these procedures on 12 patients (15 cases). The 6 cases of all patients had mild to moderate instability in the first MTC (metatarsocuneiform) joint. We estimated the clinical outcomes, the radiological findings and complications. Results: AOFAS score was improved from preoperative 41.5 points to 87.7 points lastly on average. The mean correction angle of HVA and IMA was $23.8^{\circ}$ and $6.6^{\circ}$, respectively. The mean position of tibial sesamoid was 2.67 before surgery and 0.87 after surgery. The mean shortening of the first metatarsal bone was 3.07 mm after surgery. There was no pain and complications on the first MTC joint except the breakage of screw in one case and instability of the first MTC joint was improved postoperatively. Conclusion: We obtained good clinical and radiographic outcomes in our series. So, proximal metatarsal wedge osteotomy using a single screw fixation and distal soft tissue procedure seems one of the good surgical treatments for moderate hallux valgus deformity.

Purpose: The purpose of this study was to analyze the clinical results after Steindler flexoplasty. Materials and Methods: We analyzed 6 cases who had nearly normal finger and wrist joint flexion function, but could not flex elbow joint actively because of upper arm type brachial plexus injury. We performed operation during the period from February 1997 to July 2003. There were 5 males and 1 female with mean age of 28 years (range: $19{\sim}51$ years) when Steindler flexoplasty was done. The average follow-up period was 3 years 11 months (range: 12 months${\sim}$7 years 4 months). We assessed active range of motion of elbow joint, muscle power and elbow function by Mayer & Green grade scale at last follow-up. We assessed how much they were favorable for Steindler flexoplasty and had improvement of upper extremity function and correction of deformity. Results: Postoperative, flexion range of elbow joint improved to average $111.7^{\circ}$ (range: $90{\sim}130^{\circ}$). $25.8^{\circ}$ (range: $15{\sim}45^{\circ}$) in flexion contracture and $16.6^{\circ}$ (range: $10{\sim}35^{\circ}$) in pronation contracture were remained. Range of motion of elbow joint improved to average $85.3^{\circ}$ (range: $45{\sim}105^{\circ}$). Flexion power of elbow joint improved to Grade 5 in all cases. Postoperatively on Mayer & Green grade scale, there were excellent in 3 cases(50%), good in 2 cases(33.3%), fair in 1 case(16.7%). On patient's own assessment of functional improvement, there were excellent in 4 cases(66.6%), good in 1 case(16.7%) and fair in 1 case(l6.7%). Conclusion: Steindler flexoplasty can reserve good clinical results with being improved to active flexion of elbow joint in cases who have functional hand and wrist, but paralysis upper arm muscle in brachial plexus injury.

Study Design: A case study. Purpose: To assess the chronological changes of the disease-related kyphosis after chemotherapy alone, secondly to clarify the role of growth cartilage in the healed lesion on kyphosis change, and to define the accurate prediction time in assessing residual kyphosis. Overview of Literature: None of the previous papers up to now dealt with the residual kyphosis, stability and remodeling processes of the affected segments. Methods: One hundred and one spinal tuberculosis children with various stages of disease processes, age 2 to 15 years, were the subject materials, between 1971 to 2010. They were treated with two different chemotherapy formula: before 1975, 18 months of triple chemotherapy (isoniazid [INH], para-aminosalicylic acid, streptomycin); and since 1976, 12 months triple chemotherapy (INH, rifampicin, ethambutol, or pyrazinamide). The first assessment at post-chemotherapy one year and at the final discharge time from the follow-up (36 months at minimum and 20 years at maximum) were analyzed by utilizing the images effect of the remaining growth plate cartilage on chronological changes of kyphosis after initiation of chemotherapy. Results: Complete disc destruction at the initial examination were observed in two (5.0%) out of 40 cervical spine, eight (26.7%) out of 30 dorsal spine, and six (19.4%) out of 31 lumbosacral spine. In all those cases residual kyphosis developed inevitably. In the remainders the discs were partially preserved or remained intact. Among 101 children kyphosis was maintained without change in 20 (19.8%), while kyphosis decreased in 14 children (13.7%), and increased in 67 children (66.3%) with non-recoverably damaged growth plate, respectively. Conclusions: It could tentatively be possible to predict the deformity progress or non-progress and spontaneous correction at the time of initial treatment, but it predictive accuracy was low. Therefore, assessment of the trend of kyphotic change is recommended at the end of chemotherapy. In children with progressive curve change, the deformity assessment should be continued till the maturity.

Background: Patients with rotator cuff tears are usually afflicted with shoulder pain and disability. However, it is unclear which factors are related to shoulder pain in patients with rotator cuff tears. This study was therefore undertaken to determine the factors correlated with shoulder pain in patients with painful rotator cuff tears, but without any history of trauma. Methods: We evaluated a cohort of 745 patients with painful rotator cuff tears having no trauma history, and analyzed the relationship between pain and multiple factors including demographic data, tear characteristics, and passive range of motion. Pain was analyzed with a questionnaire concerning the visual analogue scale (VAS) for pain. Tear characteristics were determined by evaluating tear size, muscle atrophy, number of torn tendons, and presence of arthritis. Multivariate linear regression analysis and chi-squared test were applied to evaluate the relationship between the VAS for pain and variable factors. Results: Shoulder pain was associated with young age (p=0.01), male sex (p=0.01) and the presence of diabetes mellitus (p<0.001). Measurements of rotator cuff tear characteristics including tear size (p=0.53), muscle atrophy (p=0.16) and the number of torn tendons (p=0.34) did not correlate with shoulder pain. Symptom duration (p=0.60) and range of motion (p>0.05) also showed no correlation with VAS for pain. Conclusions: Young age, male sex and the presence of diabetes mellitus correlated positively with preoperative shoulder pain in patients with painful rotator cuff tears without a trauma history. Combined treatment of pain management and risk factor correction could be helpful to control preoperative shoulder pain.

Purpose: The purpose of this study was to evaluate the effect and short-term results of the modified Mau osteotomy designed by the author. Materials and Methods: Seventeen feet treated with newly designed osteotomy from 2003 to 2004 were included. We performed metatarsal osteotomy and distal soft tissue procedure on 17 feet (12 patients) and additional Akin osteotomy on 6 feet (4 patients). An oblique osteotomy was made from the neck in the dorsum, aiming proximal to the base of the first metatarsal with vertical short arm on the base. We performed long arm of osteotomy parellel to the acrylic plate which was supposed as ground plane. Preoperative radiographs and follow up radiographs at three month were used for radiologic evaluation. Results: Mean hallux valgus angle was $43.6^{\circ}$ and mean intermetatarsal angle was $20.4^{\circ}$ on preoperative weight bearing radiograph. Mean amount of correction of the hallux valgus angle was $37.5^{\circ}$ and intermetatarsal angle was $14.2^{\circ}$ at three months after operation. There was no fixation loss or malunion, and the clinical result was subjectively exellent. Conclusion: More proximal rotational axis can achieve sufficient intermetatarsal angle correction, and vertical arm can provide more stable contact. So this newly modified Mau osteotomy was considered as a good alternative procedure in the treatment of severe hallux valgus.

Background: This study was conducted to investigate the effect of leg lift difference on the serratus anterior muscle and the upper trapezius muscle when a subject with winged scapula performs a scapula protraction exercise in a four-leg crawling posture. Method: Twenty normal adults and 20 subjects with winged scapula participated in the experiment. Surface EMG recordings were collected from serratus anterior muscle and back trapezius muscle during scapula protraction exercises. Scapular winging is measured with the lifting distance of scapula retraction to the back using an electronic digital caliper. In two groups of four-leg crawling posture, the two legs support, the dominant leg lifting, and the non-dominant leg lifting, including the scapula protraction, were performed. To examine the difference between groups in the variance analysis, the Bonferroni correction was used (significance level ${\alpha}=.017$). Statistical significance level ${\alpha}$ was .05. Results: There was a significant difference in serratus anterior muscle and upper trapezius muscle during push-up plus exercise in leg lifting in four-leg crawling posture, but there were no significant differences in muscle activity between serratus anterior muscle and upper trapezius muscle, and there was no significant difference according to the presence or absence of scapular winging. Conclusion: For the shoulder stability of the ipsilateral side with the serratus anterior muscle, the leg-lifting posture is effective in the four-leg crawling, and also when a subject with winged scapula chooses an exercise, lifting the ipsilateral side of leg with scapula protraction exercises at the same time may have a positive effect on scapula dysfunction.
