Juxta-articular Myxoma of the Hip: A Rare Pediatric Tumor.

Juxta-articular myxoma (JAM) is a very rare myxoid tumor in pediatric age. JAM is frequently located at large joints, particularly in the knee, and most lesions present as palpable swelling sometimes associated with pain or tenderness. Only three cases of pediatric JAM have been reported in the literature to date.

Surgical management of chronic proximal hamstring tendinopathy in athletes: a 2 to 11 years of follow-up.

Background: Proximal hamstring tendinopathy typically afflicts athletes. The poor knowledge of this pathology can lead to late diagnosis and late treatment, which in chronic cases could be challenging. Surgical treatment could resolve the symptoms and could permit the return to full sport activity also in chronic cases.

Triple pelvic osteotomy for the treatment of residual hip dysplasia. Analysis of complications.

The aim of the paper was to present the results achieved with triple pelvic osteotomy in the treatment of residual hip dysplasia, with special interest in identifying recurrences and complications and how to avoid them. 60 patients (76 hips) with developmental dysplasia of the hip (DDH), treated by the triple pelvic osteotomy according to Tönnis and modified by Vladimirov, were included in the study. Hips were evaluated radiologically with the center-edge (CE) angle, break of the Shenton-Menard arch and index of acetabular depth by Heyman-Herndon, and functionally using the Harris Hip Score (HHS).

Expression profiling of genes involved in collagen turnover in tendons from cerebral palsy patients.

Cerebral palsy (CP) is a nonprogressive central nervous system lesion clinically characterized by impairment of voluntary movement related to spasticity, time of activation, and strength of skeletal muscle. Altered muscular control may act on tendon structure and influence extracellular matrix homeostasis, in particular, collagen. The effect of spasticity on collagen turnover in CP patients' tendons has not been described previously.
