For a volumetric measurement technique to be applicable, it should be easy, rapid, and inexpensive and should carry a high interobserver reliability. We aimed to assess the interobserver reliability of a volumetric measurement technique using the Cavalier’s principle of stereological methods.Materials and methods:The computerized tomography (CT) of 15 patients with a histopathologically confirmed diagnosis of enchondroma with variant tumor sizes and localizations was retrospectively reviewed for interobserver reliability evaluation of the volumetric stereological measurement with the Cavalier’s principle, V = t × [((SU) × d) /SL]2 × Σ P.Results:The volumes of the 15 tumors collected by the observers are demonstrated in Table 1. There was no statistical significance between the first and second observers ( p = 0.000 and intraclass correlation coefficient = 0.970) an...

This study was designed to assess the N-CC length changes related to the aging process. Materials and Methods: Femur anteroposterior (AP) radiograms of 204 patients older than 20 years were reamed virtually to be 13-mm, 14-mm, and 15-mm diameter artificial medullary cavities. Patients were divided into two major groups (males and females). Each group was subdivided into four subgroups - 20-39 years, 40-59 years, above 60 years, and above 70 years. The N-CC lengths of the femur diaphysis were measured in all groups and changes were compared between the groups. Results: For the 13-mm diameter artificial medullar cavity in female groups, the mean N-CC length value in the 20-39 years age group was 13.8 ± 4 cm, mean N-CC length value in the 40-59 years group was 11.6 ± 4.3 cm, mean N-CC length value in the above 60 years group was 9.4 ± 5.3 cm, and...

We aimed to record the impact of delayed tract closure on the post-operative sub-acute and chronic anterior knee pain. Design: Ultrasonography was used to evaluate the healing pattern of portal-site tracts. Setting and Participants: 104 operated patients, followed up for one year. Puncture wounds were divided into two groups, (1) anteromedial group and (2) anterolateral group. Each group contains 104 portal-site tract. Main Outcome Measures: VAS was used to measure pain related to delayed tract healing and its association with the post-operative sub-acute and chronic knee pain. Results: Anteromedial and anterolateral tracts average total healing time was (47 days, 28 days) respectively. The median VAS of anteromedial tract after 2 weeks, one month, three months, six months and one year was (8.2, 6.3, 4, 1.9, 0.6) respectively, and for the anterolateral tract was (7.4, 5.5, 2.8, 1.2, 0.2...

We formed six groups each consisting of 10 proximal locking screws. On metal cylinder representing lesser trochanter level, we performed 3-point bending tests with compression screw and with compression tube. We determined the yield points of the screws in 3-point bending tests using an axial compression testing machine. We determined the yield point of 5 mm screws as 1963±53 N (mean±SD) with compression screw, and as 2929±140 N with compression tubes. We found 51% more locking screw bending resistance with compression tube than with compression screw (p=0,000). Therefore compression tubes instead of compression screw must be preferred at femur compression nails.

In this report, we present an unusual case of PE following knee arthroscopy. Methods: A 57-year-old woman normally active patient presented to the orthopaedic clinic has been suffering a right knee pain responseless to the medical treatment for a year. Hystory was unremarkable with the exception of hypertension and cervical biopsy. Results: An arthroscopic meniscectomy was received under spinal anesthesia after the application of an Esmarch and pneumatic tourniquet. Post-operatively first day, she was discharged. While transporting, she developed dyspnea, weakness and low-right breast pain. An immediate pulmonary angiography and cardiac echograpy demonsrated the obstruction in the right common pulmonary artery and subsegmentary occlutions in the left side. Conclusion: After a 24-hour streptokinase therapy(ST), coumadine was started. Near the end of ST, she complained a severe knee...
Nucleotide binding and oligomerization domains/caspase recruitment domain-containing protein 15 (... more Nucleotide binding and oligomerization domains/caspase recruitment domain-containing protein 15 (NOD2/CARD15) is a cytoplasmic molecule controlling apoptosis and inflammatory processes by recognizing some microbial components. We aimed to identify the frequencies of NOD2/CARD15 gene mutations in patients with gouty arthritis and to determine their possible correlation with the disease phenotype. The study included 93 patients with gouty arthritis and 51 healthy controls matched for age, gender, and ethnicity. The NOD2/CARD15 R702W and G908R gene mutations were explored by the polymerase chain reaction restriction fragment length polymorphism method while the 3020insC mutation was analyzed by DNA sequencing. The mean patient age was 54.2 ± 14.2 years and mean duration of the disease was 3.1 ± 2.9 years. The first metatarsophalangeal and finger joint involvements were detected in 72 (77.4%) and 18 (19.5%) patients, respectively. Ankle arthritis and knee arthritis were detected in 43 (...

It rarely affects patients older than 65 years old.The purpose of this study is to compare and evaluate the demographic, clinical and laboratory features of elderly-onset psoriatic arthritis (EOPsA) and young-onset (YOPsA) patients.A total of 180 patients diagnosed with PsA according to CASPAR criteria and followed-up in single center were included in this study. The patients with initial symptoms started after age 65 were accepted as EOPsA. Demographic, clinic, and laboratory data and the medications which the patients received were recorded and retrospectively evaluated.Nineteen (10.5%) of 180 patients were diagnosed as EOPsA, and 161 (89.5%) patients were evaluated as YOPsA. The mean patient age was 42.1years for the YOPsA group and 68.3 years for the elderly onset group. Mean duration of disease was 5.6 years for the early onset group and 1.3 years for the elder...

We reduced the dislocated femoral heads immediately under general anesthesia followed by passive and active exercises and early full-weight bearing mobilization. After 5 years, the result was excellent.
