However, the results varied greatly and few long term results were reported. Methods From 1998 to 2001, TRO had been done on 15 ONFH hips. The mean age of the patients was 42 years. All hips were associated with extensive lesions and in the early collapsed stage (ARCO staging system, IIIA less than 2 mm collapse in 10 hips and IIIB 2 to 4 mm collapse in 5 hips). Demographic data, Harris hip score, and radiological outcomes were reviewed. Results: Anterior rotational osteotomy was done in 11 hips and posterior rotational osteotomy was done in 4 hips. The index of necrosis was 39% in average (range, 12% to 68%). In the 15 hips with an average follow-up of 11 years, the Harris hip score improved from 39.1 to 76.2. Six hips were converted to total hip replacement in an average of 3.6 years. The overall survival rate for conversion to total hip replacement as the end point was 60%. The overall radiological success rate was 53.3% Conclusions: TRO is a worthy procedure to preserve extensive and collapsed hips with acceptable success rate. Technical difficulties while executing the surgery or converting to total hip replacement should be considered and discussed fully with the patients.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"8 1","pages":"169-175"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81722070","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}

Steinberg","doi":"10.6492/FJMD.20161201","DOIUrl":"https://doi.org/10.6492/FJMD.20161201","url":null,"abstract":"Background: To provide the best possible evaluation and treatment for patients with osteonecrosis of the femoral head (ONFH) it is necessary to determine the size of the necrotic lesion and extent of joint involvement as well as the stage. There has been a steady trend towards the use of comprehensive classifications, but there remains a difference of opinion as how best to determine lesion size. Purpose: To determine the accuracy and ease of use of various angular measurements and other techniques for measuring lesion size in ONFH. Methods: Eighteen hips with Stage I, II ONFH were evaluated using three-dimensional MRI measurements of lesion volume as the standard against which to compare simple visual estimates and area and angle measurements on plain radiographs and MRI. Results: The necrotic region occupied between 2.2% and 59% of the femoral head volume on MRI measurements. Many plain films in this specific series did not depict the lesion margins well, which made delineation, estimation and measurements of lesion size less accurate than in previous studies. There was a rough correlation between angle measurements and lesion size. This correlation was closer with the Index of Necrosis than with the Combined Necrotic Angle, which routinely overestimated size. The accuracy of the Index was improved when adjusted to reflect a femoral head angle of 250 degrees rather than 180 degrees. Numerical limits were derived with which angular measurements could be correlated for 70% of hips with Grades 〞A〞, 〞B〞 and 〞C〞 lesion size, as described in the University of Pennsylvania and ARCO classifications. Simple visual estimates from MRI studies were as accurate as angular measurements. Conclusions: For routine clinical use, visual estimates from good quality radiographs or MRI are generally satisfactory. Angular measurements do give an indication of prognosis and treatment, although they are estimates rather than true measurements of lesion size. 3-D MRI volume measurements are the most accurate method of measuring lesion size. They are now easier to use and should be considered for research and publications.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"54 1","pages":"153-160"},"PeriodicalIF":0.0,"publicationDate":"2016-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84712611","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}

Recently, new techniques have been developed in which the osteonecrotic lesion is drilled (core decompression) and/or more extensively debrided, and osteoprogenitor cells from the iliac crest are harvested, concentrated and delivered to the lesion to enhance bone healing. In the earlier stages of osteonecrosis of the hip and knee without collapse or arthritic changes in the involved joint, the intermediate term results for preserving (rather than replacing) the joint using these techniques have been very encouraging.

Fibrin and mesenchymal stem cells are used in promoting tissue repair and osteogenesis, respectively. Purposes: Tobramycin-loaded mesoporous bioactive glass (TMBG), fibrin and mesenchymal stem cells are used in this study to promote osteogenesis and against bacterial contamination in vitro. Methods: MBG was synthesized in a two-step acid-catalyzed self-assembly process with hydrothermal treatment. Tobramycin was loaded with MBG and fibrin to make a TMBG fibrin complex. The cell proliferation, osteogenic differentiation, Live/Dead staining and antibiotics inhibition zone test were evaluated for TMBG fibrin complex. Results: The experimental results showed a well-ordered hexagonally structured bioactive glass was synthesized. The TMBG fibrin complex cultivated with rabbit bone marrow mesenchymal stem cells (RBMSCs) showed good biocompatibility and increased expression of collagen type I, OPN, OCN and RUNX2 in cultivation period. The inhibition zone of TMBG fibrin complex increased while the concentration of tobramycin increased against Staphylococcus aureus and Pseudomonas aeruginosa. In addition, the TMBG fibrin complex (with 0.5% tobramycin) had the same antibacterial effect as 10 mg tobramycin.

Most tibial stress fractures occur at the posteromedial aspect of the middle third of the tibial shaft, and other less common sites of this fracture are the anterior cortex and medial malleolus. Here we report a 59-year-old man with a stress fracture located in an unusual region -- the tibial plateau, following a marathon race. The patient presented with anterior knee pain and had "negative" radiographs. Magnetic resonance imaging showed a stress fracture of the proximal tibia and partial tears of the anterior cruciate ligament, posterior cruciate ligament, and medial collateral ligament. He was treated conservatively considering the appropriate alignment of the fracture without any displacement. A long-leg splint was used, and no weight bearing was allowed on the affected leg for 9 weeks. Healing was monitored with a series of follow-up radiographs that showed sclerosis with endosteal change over the proximal tibia. The fracture eventually healed without any complications. Orthopedic surgeons should consider the possibility of a tibial plateau fracture in the context of non-traumatic knee pain after a marathon race or other high-loading activity, even if radiographs do not demonstrate a fracture. This will help in the early diagnosis and treatment of this stress fracture.","PeriodicalId":100551,"journal":{"name":"Formosan Journal of Musculoskeletal Disorders","volume":"50 1","pages":"99-103"},"PeriodicalIF":0.0,"publicationDate":"2016-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75819181","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}
