A comparison of ultrasonography and radiography in the management of infants with suspected developmental dysplasia of the hip.

The aim of this study was to determine the sensitivity and specificity of plain radiography in the detection of developmental dysplasia of the hip, using hip ultrasonography as a reference standard. A retrospective review was made in 44 infants ranging in age from 4 weeks to 50 weeks (mean age: 21.7 weeks). Both radiographic and ultrasonographic images were obtained for 86 hips. Radiography and ultrasonography were found to be significantly correlated in terms of classification of developmental dysplasia of the hip presence or absence (p < 0.0001, Fisher's exact test). With ultrasonography accepted as the standard for the diagnosis of developmental dysplasia of the hip, radiography had a sensitivity of 61% and a specificity of 87%. The results of this study suggest that the two imaging methods give similar overall results, but that low grade dysplasia detected on ultrasonography may go undetected on radiography.

Clinic and ultrasound findings related to pain in patients with knee osteoarthritis.

The aim of this study was to determine clinical and US factors associated with pain in patients with knee osteoarthritis (OA). The study included 143 patients. Patients were divided into two groups: group 1 consisted of 94 patients with unilateral or bilateral knee pain ≥3 cm during physical activity for at least 48 h prior to inclusion, measured by the visual analog scale from 0 to 10 cm. Group 2 consisted of 49 patients with knee OA without knee pain at least 1 month prior to inclusion. In both knees, range of motion was measured by goniometry and anteroposterior, and lateral knee radiographs were taken during weight-bearing. OA grading was performed in accordance with the Kellgren-Lawrence criteria by a specialist in radiology experienced in this field. A knee ultrasound (US) examination was performed in all patients by a blinded radiologist. Women were more often symptomatic than men (p < 0.005). Patients in group 1 tended to have a higher body mass index (BMI; p<0.001). Radiographic grades III (52.1%) and II (37.2%) were most frequently found in group 1, whereas I (30.6%), II (46.9%), and III (22.4%) were found in group 2. When radiographic grades in both groups were compared, group 1 had greater radiographic grades than group 2 (p<0.001). US findings in group 1 were effusion of the suprapatellar pouch (72.3%), Baker's cyst (42.6%), protrusion of the anterior horn of the medial meniscus associated with medial collateral ligament displacement (9.6%), and loose body (9.6%). In group 2, the only US finding was Baker's cyst (6.1%). Regression analysis revealed that BMI, degree of knee flexion, and thickness of the quadriceps tendon were factors that were related with pain in the knee. Increased BMI, decrease in the degree of knee flexion, and decreased quadriceps tendon thickness are factors that increase the risk of pain in knee OA.

[Phalanx-like osseous structure posterior to the cervical vertebrae: a hitherto unreported location for a rare anomaly]. / Servikal vertebra posteriorunda falanks benzeri ektopik kemik yapi: Nadir bir anomali için bildirilmemis bir yerlesim bölgesi.

Several types of abnormalities of the vertebral column have been reported. Pelvic rib or pelvic digit is a rare congenital anomaly of the spine. A 58-year-old male patient presented with a complaint of a firm mass in the neck. He had no history of trauma and had been aware of the mass for years. Physical examination showed a painless and immobile mass in the neck, measuring 4 x 1 cm. About 10 to 15 degrees of restriction was noted in neck movements, with slight pain. A plain radiograph of the cervical region showed two bony formations resembling a coccygeal segment or a phalanx, posterior to the spinous process of the C6 vertebra. They had well-defined cortices and medullae and pseudo-articulation between each other and with the spinous process. These findings were confirmed by three-dimensional computed tomography and magnetic resonance images. The patient did not accept surgery for the lesions were not associated with a significant discomfort. To our knowledge, such a digit has hitherto not been reported in the cervical region.

An extremely uncommon infection: Candida glabrata arthritis after total knee arthroplasty.

Prosthetic arthritis caused by Candida species is extremely rare. Of 30 such cases reported in the English literature, only 3 were due to Candida glabrata. We present herein a fourth case; to the best of our knowledge this is the first example of knee arthroplasty infection caused by C. glabrata.
