An analysis of orthopaedic theses in Turkey: Evidence levels and publication rates.

BACKGROUND: The aim of this study was to present characteristics and publication patterns of studies arise from orthopedic theses obtained from National Thesis Center; database in terms of publication years, study types, topics, level of evidence between 1974 and 2014. METHODS: Firstly, National Thesis Center database was searched for orthopedics and Traumatology theses. The theses, which their summary or full text were available were included in the study. The topics, study types and quality of study designs were reviewed. Then theses were searched in the PubMed database. Journals of published theses were classified according to category, scope and impact factors of the year 2014. RESULTS: 1508 theses were included into the study. Clinical studies comprised 71,7% of the theses, while 25,6% of the theses were non-clinical experimental and 2,7% of the theses were observational studies. Clinical studies were Level I in 8,6% (n = 93) and Level II in 5,8% of the theses (n = 63). A total of 224 theses (14,9%) were published in the journals indexed in PubMed database from 1974 to 2012. Fifty-two (23,2%) were published in SCI; 136 theses (60,7%) were published in SCI-E journals and 36 theses (16%) were published in other Journals indexed in PubMed. CONCLUSION: The quantity and quality of published theses need to be improved and effective measures should be taken to promote quality of theses. Theses from universities and Training hospitals which did not allow open access, and; incomplete records of the National Thesis Center database were major limitations of this study.

The Current Perspectives of Stem Cell Therapy in Orthopedic Surgery.

CONTEXT: Musculoskeletal injuries may be painful, troublesome, life limiting and also one of the global health problems. There has been considerable amount of interest during the past two decades to stem cells and tissue engineering techniques in orthopedic surgery, especially to manage special and compulsive injuries within the musculoskeletal system. EVIDENCE ACQUISITION: The aim of this study was to present a literature review regarding the most recent progress in stem cell procedures and current indications in orthopedics clinical care practice. The Medline and PubMed library databases were searched for the articles related with stem cell procedures in the field of orthopedic surgery and additionally the reference list of each article was also included to provide a comprehensive evaluation. RESULTS: Various sources of stem cells have been studied for orthopedics clinical care practice. Stem cell therapy has successfully used for major orthopedic procedures in terms of bone-joint injuries (fractures-bone defects, nonunion, and spinal injuries), osteoarthritis-cartilage defects, ligament-tendon injuries, femoral head osteonecrosis and osteogenesis imperfecta. Stem cells have also used in bone tissue engineering in combining with the scaffolds and provided faster and better healing of tissues. CONCLUSIONS: Large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells.

Spinal Tuberculosis.

Spinal tuberculosis (TB) is a significant form of TB, causing spinal deformity and paralysis. Early diagnosis and treatment are crucial for avoiding multivertebral destruction and are critical for improving outcomes in spinal TB. We believe that appropriate treatment method should be implemented at the early stage of this disease and that the Gulhane Askeri Tip Akademisi classification system can be considered a practical guide for spinal TB treatment planning in all countries.

Comparison of four different reduction methods for anterior dislocation of the shoulder.

BACKGROUND: Shoulder dislocations account for almost 50% of all major joint dislocations and are mainly anterior. OBJECTIVE: The aim is a comparative retrospective study of different reduction maneuvers without anesthesia to reduce the dislocated shoulder. METHODS: Patients were treated with different reduction maneuvers, including various forms of traction and external rotation, in the emergency departments of four training hospitals between 2009 and 2012. Each of the four hospitals had different treatment protocols for reduction and applying one of four maneuvers: Spaso, Chair, Kocher, and Matsen methods. Thirty-nine patients were treated by the Spaso method, 47 by the Chair reduction method, 40 by the Kocher method, and 27 patients by Matsen's traction-countertraction method. All patients' demographic data were recorded. Dislocation number, reduction time, time interval between dislocation and reduction, and associated complications, pre- and post-reduction period, were recorded prospectively. No anesthetic method was used for the reduction. RESULTS: All of the methods used included traction and some external rotation. The Chair method had the shortest reduction time. All surgeons involved in the study agreed that the Kocher and Matsen methods needed more force for the reduction. Patients could contract their muscles because of the pain in these two methods. The Spaso method includes flexion of the shoulder and blocks muscle contraction somewhat. The Chair method was found to be the easiest because the patients could not contract their muscles while sitting on a chair with the affected arm at their side. CONCLUSIONS: We suggest that the Chair method is an effective and fast reduction maneuver that may be an alternative for the treatment of anterior shoulder dislocations. Further prospective studies with larger sample size are needed to compare safety of different reduction techniques.

Preservative solution for skeletal muscle biopsy samples.

CONTEXT: Muscle biopsy samples must be frozen with liquid nitrogen immediately after excision and maintained at -80°C until analysis. Because of this requirement for tissue processing, patients with neuromuscular diseases often have to travel to centers with on-site muscle pathology laboratories for muscle biopsy sample excision to ensure that samples are properly preserved. AIM: Here, we developed a preservative solution and examined its protectiveness on striated muscle tissues for a minimum of the length of time that would be required to reach a specific muscle pathology laboratory. MATERIALS AND METHODS: A preservative solution called Kurt-Ozcan (KO) solution was prepared. Eight healthy Sprague-Dawley rats were sacrificed; striated muscle tissue samples were collected and divided into six different groups. Muscle tissue samples were separated into groups for morphological, enzyme histochemical, molecular, and biochemical analysis. STATISTICAL METHOD USED: Chi-square and Kruskal Wallis tests. RESULTS: Samples kept in the KO and University of Wisconsin (UW) solutions exhibited very good morphological scores at 3, 6, and 18 hours, but artificial changes were observed at 24 hours. Similar findings were observed for the evaluated enzyme activities. There were no differences between the control group and the samples kept in the KO or UW solution at 3, 6, and 18 hours for morphological, enzyme histochemical, and biochemical features. The messenger ribonucleic acid (mRNA) of ß-actin gene was protected up to 6 hours in the KO and UW solutions. CONCLUSION: The KO solution protects the morphological, enzyme histochemical, and biochemical features of striated muscle tissue of healthy rats for 18 hours and preserves the mRNA for 6 hours.

Prevalence and distribution of musculoskeletal disorders causing unfitness for military service among young adult men: An epidemiologic study.

OBJECTIVES: The aim of this cross-sectional epidemiologic study was to investigate the prevalence and distribution of musculoskeletal disorders causing unfitness to Turkish Military Service. METHODS: This study has been carried out by examining the medical reports of 1.777.500 people who applied to the Turkish Armed Forces for military service between 2009-2011. Age and geographic region of individuals were compiled and organized in groups. Musculoskeletal disorders were classified mainly as fracture sequel, spine disorders, absence of phalanges, extremity amputation, aggressive or multiple benign tumors of bones and pes planus. RESULTS: Unfitness to military service caused by musculoskeletal disorders was found to be 6.53‰ in 2009, 7.10‰ in 2010 and 7.28‰ in 2011. The prevalence of musculoskeletal diseases has increased by years. The prevalence of fracture squeal by years was found to be 2.83‰ in 2009, 3.10‰ in 2010 and 3.03‰ in 2011. In this study, the most common musculoskeletal disorders were: limitation of joint mobility (0.89‰), degeneration of joint surface (0.69‰), lower and upper limb discrepancies (0.60‰), posterior fusion surgery (0.59‰) and the absence of the phalanges in hand (0.51‰). We found an increase in both the prevalence of posterior fusion surgery and the absence of the phalanges in study group. CONCLUSION: These results has given information about severe musculoskeletal disorders among young adult male in Turkey. New studies including young adult female will add important information to our knowledge about musculuskelatal problems in our community.
