Purpose: We are proposing a new method of assessing elbow deformity via the its rotational axis, calculated from data obtained by the motion analysis system, in order to provide orthopedic surgeons a better understanding of the elbow deformities before or during surgical corrections. Methods: Osteotomy was performed at the supracondylar region of humerus on a fresh-frozen cadaver, and the bone fragments were adjusted with a set of external skeletal fixator (ESF). Cycles of elbow flexion and extension were then performed passively, and the coordinates of the markers on both humerus and ulna were recorded by an ultrasonic motion analysis system. Mathematical algorithm was developed and the elbow rotation axis was determined by the normal vector of the best fitting plane calculated through random sample consensus (RANSAC) method. Five different elbow conditions in varus/valgus deformities as well as internal/ external rotations were created by adjusting the ESF, and three sets of data were collected for each condition. Results: The best fitting plane method was able to reduce the shifting of the marker positions from 11 mm to less than 4 mm, and the deformities calculated from each elbow rotation axis were found to be within 50 of the expected value.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"350 1","pages":"97-106"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76570088","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many studies have reported that UKA is a suitable procedure with reliable results in Caucasians, few studies have reported the clinical outcomes in Asians. This study reports our experience of the use of imported knee prostheses in a Chinese population. Methods: Forty-five patients with medial compartmental osteoarthritis who had undergone UKA 6 to 10 years previously were retrospectively followed up. All of the cases received Zimmer high flex system UKA. Pain score of Knee Society Score (KSS), KSS functional score and anatomic tibiofemoral angle, was recorded pre-operatively and post-operatively. The satisfaction rate and radiolucent line beneath the tibial component were also recorded at last follow-up. Results: The average KSS pain score was 13.7 pre-operatively and 43.4 post-operatively. The average KSS functional score was 45.7 pre-operatively and 78.3 post-operatively. The average anatomic tibiofemoral angle was 0° pre-operatively, 3° immediately postoperatively, and 4.6° at last follow-up. Radiolucent lines beneath the tibial component were observed in 40% of the cases and not correlated with poor functional outcomes or pain scores. Only one patient felt unsatisfied with the surgery. Conclusions: The patients who received UKA had good pain relief and acceptable functional performance in this study. The imported knee prostheses provided satisfactory results in this Chinese population, however not as good as those reported in Caucasians. Strict patient selection and good knee alignment are the crucial factors for UKA.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"6 1","pages":"68-75"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89784375","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is well suited for direct debridement, reconstruction of the anterior column, correcting the kyphotic deformity, and posterior decompression of the spinal cord. The spine, however, may be unstable between stages. Sequentially staged operations require a long overall operating time and chest tube placement because of thoracotomy for the thoracic spine, thereby increasing the risk of complications. Purposes: To evaluate the clinical outcome and infection control of spondylodiscitis after debridement of the thoracic spine by the modified costotransversectomy Methods: Between November 2009 and October 2012, a total of 11 patients (7 male, 4 female) with pyogenic and mycobacterial thoracic spondylodiscitis underwent one-stage modified costotransversectomy for disc and endplate debridement, disc space reconstruction, and posterior instrumentation. Results: Each patient displayed clinical and laboratory improvement after the surgical intervention. The average preoperative C-reactive protein (CRP) level and peripheral white blood cell count (WBC) were compared with the levels 7 days postoperatively: CRP (166.2 ± 31.4 vs. 77.5 ± 13.9; p = 0.002) and WBC (13.7 ± 1.1 vs. 10.7 ± 0.5; p = 0.009). Clinical functional results measured by the Oswestry Disability Index preoperatively and at discharge were 69% and 53%, respectively, indicating more than 10% improvement (p ＜ 0.001). The average kyphosis angle postoperatively was 14.7° ± 2.1° vs. 23.1° ± 2.6° preoperatively (p ＜ 0.001). Conclusions: The modified costotransversectomy approach for treating thoracic spine infection is a safe, effect alternative treatment with fewer complications than with traditional surgery and encouraging clinical outcomes.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"4 1","pages":"59-67"},"PeriodicalIF":0.0,"publicationDate":"2014-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88858800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding their demographic characteristics and their hospital baseline outcomes, including length of stay (LOS) and medical costs, is important to optimizing pre-operative planning. Objectives: Compare the demographic characteristics, LOS and medical costs of INFH and OA patients from Taiwan who underwent THA. This study used Taiwan's National Health Insurance Research Database (NHIRD). Methods: Using the claim data for in-hospital medical resource utilization of one million patients from January 1, 1996 to December 31, 2010, we identified 1,019 INFH and 1,169 OA diagnosis with THA procedure data. We compared these patients in terms of sex, age, Charlson Comorbidity Index (CCI) score, hospital level, hospital location, surgeon's age and hospital medical fees. The variables related to LOS were statistically analyzed by linear regression and multiple linear regression to identify correlations between the two groups. Results: There were statistically significant differences in age, sex, CCI score, hospital level, hospital location, surgeon's age, laboratory fees, and anesthesia fees between the INFH and OA patients. The mean age of the INFH THA patients, who were predominantly male (INFH, 79.6%; OA, 38.8%) was younger (47 years) than that of the OA THA patients (64 years). However, there was no significant difference in the average LOS and total medical expenses between the two groups. Regardless of disease entity, the THA patients' LOS was found to be shorter in female patient, lower CCI score, medical center, order surgeon's age and hospital location of northern area. Conclusions: INFH and OA patients undergoing THA have unique demographic characteristics. The variables related to LOS, include patient's sex, CCI score, hospital level, hospital location, and surgeon's age, will help surgeons to more accurately inform patients during the THA preoperative planning stage.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"54 1","pages":"9-17"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86082658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We collected 132 consecutive patients (36 patients for ACF group and 96 patients for EOLP group) at our institution from 2005 to 2011. Preoperative data of both groups were compared. Functional recovery rates, radiographic changes, and complications of the two groups were analyzed. Results: There were no significant difference over age, Japanese orthopedic association (JOA) score, existence of myelomalacia, and cervical range of motion (ROM) between ACF and EOLP groups (p ＞ 0.05). Preoperative Pavlov ratio, axial and sagittal compressive ratios were significant smaller in EOLP and preoperative cervical curvature was less lordotic with more neck pain cases in ACF group (p ＜ 0.05). In ACF group, 1 year functional recovery rate is 83.71 ± 15.61 and Nurick score also significantly improved. Neck pain visual analogue scale (VAS) decreased at postoperative 2 weeks and 3 months. Cervical lordotic angle increased and cervical ROM decreased at postoperative 12 months. Complications include 1 temporary odynophagia, 1 temporary dysphonia, 1 screw loosening, 1 allograft malposition, 1 fusion collapse and 1 pseudarthrosis cases. In EOLP group, 1 year functional recovery rate is 70.22 ± 21.25% and Nurick score also greatly improved. Neck pain VAS increased at postoperative 2 weeks and then decreased at 3 months. Cervical lordotic angle decreased at postoperative 12 months. Cervical ROM decreased at postoperative 3 months and then restored to preoperative degrees at postoperative 12 months. Complications include 5 aggravated neck pain and 3 reversible C5 nerve palsy cases. Conclusion: EOLP had good effect on more stenotic type and ACF benefited painful and kyphotic type MCSM.

It is one of the most common causes of death from a single infectious agent worldwide. All of current diagnostic methods, including Mantoux test, acid-fast bacilli (AFB) smear and culture, AFB staining, and nucleic acid amplification, have their own shortcoming and are difficult to perform in low-income countries where TB patients are most common. Therefore, the purpose of our study was to determine the optimal complementary oligonucleotide sequence to hybridize to the target fragment of IS6110 (a target sequence extracted from TB patients) and optimal the condition, in order to provide a more rapid, cost-effective, convenient, and reliable diagnostic tool for tuberculosis via the colorimetric gold nanoparticles (AuNPs) and microfluidic paper-based analytical devices (μPAD) device to detect Mycobacterium tuberculosis. Methods: To determine the optimal condition for ssDNA oligonucleotide sequence for hybridization, same combination of oligonucleotide sequences under identical annealing temperature and duration, with 1:1 ratio of ssDNA and dsDNA, were tested under different denaturation temperatures and durations. Seven different oligonucleotide sequences were then compared to determine the ideal sequence for hybridization. The band intensity on gel electrophoresis was analyzed by UV-light transilluminator. Results: The gel electrophoresis results revealed that oligonucleotide sequence 5'-CTC GTC CAG CGC CGC-3' and 5'-TAG GCG TCG GTG ACA-3' yielded the highest hybridization rate with the 123 bp target sequence of IS6110. Conclusion: The colorimetric sensing method of gold nanoparticles possesses the potential of being a highly accurate, user-friendly, rapid, and equipment-free diagnostic tool for detecting Mycobacterium tuberculosis.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"61 1","pages":"25-34"},"PeriodicalIF":0.0,"publicationDate":"2014-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82299726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
