Biomechanical evaluation of a second generation headless compression screw for ankle arthrodesis in a cadaver model.

Background: Many types of screws, plates, and strut grafts have been utilized for ankle arthrodesis. Biomechanical testing has shown that these constructs can have variable stiffness. More recently, headless compression screws have emerged as an evolving method of achieving compression in various applications but there is limited literature regarding ankle arthrodesis.

Dislocated Posterior Tibial Tendon Treated With Plate Buttress Fixation in a Collegiate Gymnast: A Case Report and Review of the Literature.

Unlabelled: Dislocation of the posterior tibial tendon (PTT) is a rare pathological process that occurs most often as a result of acute trauma. The injury involves forced dorsiflexion and eversion of the foot against a contracted posterior tibialis. Diagnosis of the injury is often difficult secondary to the rarity of the injury and its similarity with other benign injuries of the medial ankle.

Application of biologics in the treatment of the rotator cuff, meniscus, cartilage, and osteoarthritis.

Advances in our knowledge of cell signaling and biology have led to the development of products that may guide the healing/regenerative process. Therapies are emerging that involve growth factors, blood-derived products, marrow-derived products, and stem cells. Animal studies suggest that genetic modification of stem cells will be necessary; studies of cartilage and meniscus regeneration indicate that immature cells are effective and that scaffolds are not always necessary.

Diagnostic cervical lymphadenectomy in children: a case for multidisciplinary assessment and formal management guidelines.

A retrospective review was carried out of all children under 16 years of age that underwent cervical lymphadenectomy in our department within a 7-year period. The pathway of their referral from the community to hospital care was noted. The circumstances surrounding the decision for surgery, including clinical features of lymph nodes and investigation results were also recorded.

Anatomic landmarks for locating parotid lesions in relation to the facial nerve: cross-sectional radiologic study.

Objectives: To determine the accuracy of using surrogate anatomic structures radiologically to predict the relation of parotid lesions to the intraparotid facial nerve.

Setting: Tertiary centre.

Design: Retrospective.
