OBJECTIVES: The aim of the present study was to propose a methodologically innovative sonographic approach for optimal evaluation of synovial tissues (starting from histopathology). METHODS: Using high-frequency ultrasound probes and high-level ultrasound machines, we matched the histological microarchitecture of synovial tissues with multiple sonographic patterns in physiological and pathological conditions. Likewise, high-sensitive color/power Doppler assessments have also been performed to evaluate the microcirculation. RESULTS: Modern equipment allows for a macroscopic classification of synovial pathologies recognizing different morphological patterns; however, intimal and subintimal layers of the synovium cannot be distinguished from each other on ultrasound. High-sensitive Doppler imaging clearly defines the microvascular pattern, especially in patients with hypertrophic synovial pathologies. CONCLUSIONS: In clinical practice, using adequate technological equipment i.e. high-frequency B-mode and high-sensitive Doppler imaging, detailed sonographic assessment of synovial tissues can be performed - defining the main sono-histological patterns.
We describe and discuss autopsy findings of synovial membrane hemorrhage and bloody discoloration of synovial fluid ("inner knee sign") within a study population comprising 36 cases of fatal hypothermia and 300 control cases. Synovial membrane hemorrhage and bloody discoloration of synovial fluid of the knees were seen in 27 cases of fatal hypothermia (75%). Though we are not dealing here with an obligatory autopsy finding in fatal hypothermia, the detection of the inner knee sign might be used as another corroborative sign of vital hypothermia after considering all differential diagnostic aspects. However, the absence of this finding does not exclude death due to hypothermia.

PURPOSE: The aim of the study was to describe the retinacula of Weitbrecht in the adult hip. MATERIALS AND METHODS: Specimens were obtained from 30 adult hips, average age was 77 years (age range 43-91 years), 8 specimens were fixed by formalin solution and 22 were not fixed. RESULTS: Anterior retinaculum was found in 40% of examined specimens. The anterior retinaculum was in 83% of cases formed by a flat plate and in 17% by two to three parallel bands. Medial retinaculum was present constantly, extending from the attachment of the articular capsule at the base of the lesser trochanter towards the fovea capitis femoris as far as the edge of the articular cartilage. Typically, the retinaculum had the form of an inverted "T". Of the three retinacula, the medial one was the strongest. Lateral retinaculum was also present constantly. In 89% of cases, it had the form of a quadrilateral plate adjacent to the upper surface of the femoral neck. This plate arises from the insertion of the articular capsule on the upper part of the femoral neck at the base of the greater trochanter close to the trochanteric fossa. The plate extended along the upper edge of the femoral neck as far as the edge of the articular cartilage. Microscopic examination revealed fine blood vessels running through the retinacula. CONCLUSION: Lateral retinaculum and medial retinaculum are constant synovial plicae in terms of both occurrence and localization. Nutritive arteries run through both the plicae to supply the femoral head.
