Objective The aim of this study was to analyze the survivorship and clinical outcome of Cementless Spotorno (CLS) stem in young patients. Methods A total of 99 consecutive hip arthroplasties using CLS stem were performed on 84 patients younger than 50 years of age between 1993 and 2001. 63 patients were available for final follow-up (mean age: 39 ± 7.8 (range: 22–50)). Patients' Harris Hip Scores (HHS) and survivorship estimates were calculated. Radiographs were analyzed for acetabular implant status, canal fill index (CFI), stem alignment, osteolysis, and stress shielding. Results Mean follow-up time was 18 years (13–3), and mean HHS was 88.7 (58–100). Patients with femoral neck fracture had a more favorable functional outcome (p = 0.027), while those with stems in varus had lower scores (p = 0.017). 31 stems (49%) were undersized and 30 hips (47%) had perifemoral osteolysis. Acetabular impairment was strongly associated with osteolysis in Gruen zones 1 and 7 (p < 0.01). Seventeen of the osteolytic lesions occurred in Gruen zone 1, 4 lesions in zone 2, 9 in zone 6 and 22 in zone 7. Forty nine stems were well aligned, 10 were in varus and 5 in valgus. Six patients presented with grade 1 stress shielding, 42 with grade 2, 9 with grade 3 and 7 with grade 4. Pedestal formation was evident in 13 cases. Kaplan-Meier survivorship estimates at 18 years with revision for any reason as the end point and with septic revisions excluded were 91.2% (95% CI: 83.7%–98.7%) and 95.1% (95% CI: 89.5%–100%), respectively. There was no difference between survival estimates of patients with different etiologies. Conclusion CLS stems in young patients have high survival estimates in the long term with good-excellent results. Spotorno stems perform equally well in all etiologies with no difference in terms of survivorship. Level of Evidence Level IV Therapeutic study. ER -

Distal radius fractures are the most common type of all extremity fractures. It is generally accepted that fractures with more than 2 mm step-off in the radiocarpal joint and greater than 10 degrees dorsal tilt should be treated surgically. However, the ideal technique for surgical management is still a point of debate. We performed cross-sectional data analysis to compare the results of three treatments methods - volar locking plate (VLP), external fixation (EF), Kirschner wire (K-wire) - in patients with distal radius fractures, and compared the clinical, functional, and radiological results Forty-four patients with distal radius fractures who underwent fixation with VLP, K-wire or EF between 2011 and 2013 were included in the study. All fractures were classified according to the Müller’s Arbeitsgemeinschaft für Osteosynthesefragen (AO) and Frykman's classifications. Routine radiographs were taken at the postoperative three weeks, six weeks, and three months. Radial inclination, volar tilt, radial length and ulnar variance were assessed on the follow-up visits and additionally at the follow -up for the study. The patient-based Disabilities of the Arm, Shoulder and Hand (DASH) score system and the physician-based MAYO scale were used to evaluate functional outcomes. Radiological and functional outcomes between three surgical modalities were compared and statistically analyzed. The average age at the time of surgery was 52 years (range = 35-69 years). Of a total of 44 patients, 28 were operated with VLP, 11 were with K-wire and five with EF. Satisfactory reduction was achieved in all fractures, and all of the fractures healed. DASH and MAYO scores were similar in all groups. Regarding radiographic parameters, there was no significant difference in radial inclination, volar tilt, radial length and ulnar variance between the treatment modality groups. When evaluated based on fracture geometry, the DASH score was significantly higher in the patients with AO23A type fracture compared to the patients with AO23B and AO23C type fractures. As for MAYO score, all AO23 groups had similar outcomes. Surgical treatment options VLP, EF, and K-wire provide adequate fixation, satisfactory radiological, and functional results for the management of distal radius fractures of various severities. The optimal treatment approach depends on individual features, and the choice for an internal fixation or closed reduction method for the restoration of wrist function should be evaluated thoroughly by the operating surgeon considering the patient-related variations.

The prevalence of musculoskeletal complications in diabetes mellitus (DM) increases with the duration of disease and with poor glycemic control. Our aim was to evaluate lower extremity musculoskeletal complications in patients with DM using the Glasgow Ultrasound Enthesitis Scoring System, and to reveal the relationship between clinical and sono-graphic findings. A total of 67 patients (25 men, 42 women) with DM were included in the study. All the diabetic patients were selected if they did not have any symptom of muscu-loskeletal system in the lower extremities. They were divided into four groups. Ultrasonographic assessment was performed according to the Glasgow Ultrasound Enthesitis Scoring System with an Esaote MyLab 5 device equipped with a 5-13 MHz linear transducer. Correlation between diabetes duration and lower extremity enthesopathy scores were evaluated. There was a significant correlation between duration of DM and total Glasgow Ultrasound Enthesitis Scoring System scores (p < 0.001). In addition, duration of DM was significantly correlated with enthesophyte scores and erosion scores (both p < 0.001). There was a significant difference among Groups 1 -4 for the mean enthesophyte score and mean erosion score (both, p < 0.001). Musculoskeletal ultrasonography is an effective, inexpensive, and useful tool without radiation for evaluating diabetic patients for the early diagnosis of musculoskeletal complications.

Objective The aim of this study was to compare the radiological and functional results of posterior cruciate ligament (PCL) – retaining and posterior-stabilized total knee arthroplasties in patients with severe varus gonarthrosis. Methods Medical records of 112 knees of 96 patients who underwent total knee arthroplasty for severe varus (?15°) were reviewed. PCL-retaining and PCL-stabilizing groups consisted of 58 and 54 knees, respectively. Mean follow-up time was 56.6 months (range: 24–112 months). Knee Society (KS) clinical rating system was used in clinical evaluation. Range of motion, degree of flexion contracture, postoperative alignment, and complication rates were compared between the groups. Results Mean preoperative mechanical tibiofemoral angle was 20.1° in varus alignment, and was restored to 4.6° in valgus postoperatively. No statistically significant differences were found between PCL-stabilizing and PCL-retaining groups when KS knee scores, function scores, and flexion arc were evaluated. Two patients in PCL-retaining group underwent revision surgery due to aseptic loosening of tibial component. One patient in PCL-stabilizing group needed arthrotomy due to patellar clunk syndrome. Conclusion There were no notable differences between the 2 groups and PCL-retaining design had outcomes as good as PCL-stabilizing total knee implant in osteoarthritic knees with severe varus deformity.
