Background:Anterior cruciate ligament (ACL) reconstruction with ST autograft is sometimes unsuccessful because of harvested thin graft. Magnetic resonance imaging (MRI) can be a useful tool to evaluate the thickness of the graft. This study is performed to evaluate whether there is any correlation between diameters and cross-sectional area (CSA) of the semitendinosus tendon (ST) on the preoperative magnetic MRI and the diameter of the 4-stranded ST autograft in ACL reconstruction.Materials and Methods:Seventy patients who underwent single-bundle ACL reconstruction with 4-stranded ST for full-thickness ACL ruptures were included in this study. Anteroposterior (AP) and mediolateral (ML) diameters of ST at the levels of the joint line (JL) and femoral physeal line (PL), and also CSA at these levels were measured on T2-weighted fat-suppressed MRI examinations. The data obtained were compared with intraoperatively measured diameters of 4-stranded ST autograft. Correlations between variables were evaluated using Spearman's rho. Receiver operating characteristic and area under the curve statistics were used to evaluate the cut-off value for the correlation between 4-stranded ST graft diameter of 8 mm and CSA (mm2) on MRI.Results:On MRI measurements, no correlation was found between AP diameters at the level of the JL and 4-stranded ST diameter (P = 0.180). However, correlations were found between diameter of 4-stranded ST and ML diameter at the level of JL (P = 0.003) and PL (P = 0.002), AP diameter at the level of the PL (P = 0.009), CSA at the level of the JL (P < 0.001) and at the level of PL (P < 0.001). Correlation between the diameter of 4-stranded ST and CSA at both levels was more significant than that between AP-ML diameters of ST and diameter of autograft. The cut-off value for the 8 mm diameter CSA of 4-stranded ST was 5.9 mm2 at the JL and 8.99 mm2 at the PL.Conclusion:Preoperative MRI evaluation of CSA at the JL of the ST is a reliable parameter to predict graft size. Other graft alternatives should better be considered if the CSA of ST is <5.9 mm2 at the level of the JL.
Background. The purpose of our study is to compare the results of supine and lateral decubitus positions for total hip arthroplasty (THA) with the direct lateral (DL) approach in overweight and obese patients. Methods. Patients who had a THA with the DL approach using the lateral decubitus position (LD group) (n=54) or supine position (S group) (n=45) were retrospectively investigated. Demographic characteristics, age, and body mass indexes were calculated. Blood loss of patients, amount of transfusion, Harris Hip Scores (HHSs) (preop, 6 weeks, 3 months, 6 months, and 12 months), incision size, surgery time, postoperative acetabular cup inclination angle, femoral stem alignment, follow-up period, hospital stay, preoperative-postoperative leg length inequality, and complication rates (infection, wound site problems, and dislocation rates) were compared. Results. Both groups did not differ from each other by means of age, gender, BMI, and affected side (p=0.814, p=0.723, p=0.582, and p=0.833, respectively). The incision length (p<0.001), blood loss (p=0.010), and amount of blood transfused (p=0.002) were significantly higher in the S group than in the LD group. The surgical time was significantly longer in the S group (p<0.001). There were no statistically significant differences between the LD and S groups in terms of pre- and postoperative height, cup inclination, stem alignment, duration of hospital stay, and follow-up period. The change between pre- and postoperative HHS in the LD and S groups was statistically significant. Post hoc binary comparison analysis was conducted to investigate the difference between the groups. The values of HHS were significantly increased from the preoperative period to the final follow-up. Conclusions. The LD and S groups had comparable functional outcomes one year postoperatively. However, the S group was associated with worse intraoperative outcomes than the LD group.
Rosai-Dorfman disease is a rare proliferative histiocytic disorder of unknown etiology. It is a unique disorder of the lymph nodes but extranodal sites such as bone, skin, central nervous system, upper respiratory tract and soft tissue may be affected. Rosai-Dorfman disease is presented with massive, symmetrical cervical lymphadenopathy, fever, leucocytosis, elevated sedimantation rate and hipergamaglobulinemia. Soft tissue presentation can masquerading as a sarcoma. 61 year old women referred with painless left thigh mass to our hospital. After a excisional biopsy histopathologic results showed sheets of histiocytes with emperipolesis admixed in a mixture of inflammatuary cells including plasma cells and lymphocytes. Additionally, we observed pseudovascular spaces and asteroid bodies in large histiocytes. After surgery the patient has been followed up for 1 year postoperatively, without any sign of reccurence. We herein report a case of soft tissue Rosai-Dorfman disease wich presented with unusual features such as pseudovascular spaces and asteroid bodies in histiocytes.
