Coalitions of the Tarsal Bones.

Tarsal coalitions are the result of impaired mesenchymal separation of the tarsal bones. The most common types include calcaneonavicular or talocalcaneal coalitions. Subtalar stiffness results in pathologic kinematics with increased risk of ankle sprains, planovalgus foot deformity, and progressive joint degeneration.

Preserving the lower extremity after severe devolving injuries to meet the patient's demand in two cases: (Limb salvage after degloving injury).

Background: Severe injuries of the foot are a life-changing event. They often lead to some form of disability, and are therefore very challenging to manage. Injuries of the extremity, especially the foot and ankle, are distinct predictors of poor outcome in polytrauma patients.

Ten Years' Follow-Up on Combined Palmar and Dorsal Internal Fixation of Complex Distal Radius Fractures.

Complex distal intra-articular radial fractures (AO Type C3) are rare, but are life-changing injuries. They are usually related to high-velocity trauma mechanisms in a working male population.We surveyed a cohort of these fractures treated in our institution to assess the functional long-term outcome.

Use of peripheral blocks and tourniquets in foot surgery: A survey of Australian orthopaedic foot and ankle surgeons.

Background: The most common reasons for unplanned admission to the hospital from outpatient surgery have the potential to be minimised or eliminated by peripheral nerve blocks (PNB). Tourniquets are commonly used in elective extremity surgery but it's use is mostly guided by personal preferences and does no correlate with the existing literature. Our aim was to explore the current practice of PNB and tourniquet use by foot and ankle surgeons in Australia.

Surgical management of hallux valgus and hallux rigidus: an email survey among Swiss orthopaedic surgeons regarding their current practice.

Background: Various clinical and radiological criteria have been suggested to choose one of the numerous techniques in surgical treatment of hallux valgus and rigidus. We hypothesized that the surgeons' professional background will influence that choice depending on specialization, age, type and institution of training as well as his orthopaedic cultural orientation. Since Switzerland is characterized by regional languages (the most important being German and French), we were interested to learn if the linguistic differences had an influence on the orientation of the surgeons towards e.

Generation and characterization of osteochondral grafts with human nasal chondrocytes.

We investigated whether nasal chondrocytes (NC) can be used to generate composite constructs with properties necessary for the repair of osteochondral (OC) lesions, namely maturation, integration and capacity to recover from inflammatory burst. OC grafts were fabricated by combining engineered cartilage tissues (generated by culturing NC or articular chondrocytes - AC - onto Chondro-Gide® matrices) with devitalized spongiosa cylinders (Tutobone®). OC tissues were then exposed to IL-1β for three days and cultured for additional 2 weeks in the absence of IL-1β.

The triceps reflecting approach (Bryan-Morrey) for distal humerus fracture osteosynthesis.

Background: "Chevron"-Olecranon osteotomies are commonly used for the approach to intraarticular distal humerus fractures but are often associated with procedure related complications. We studied the triceps reflecting approach (TRA) with preservation of the extensor apparatus as a safe alternative giving a sufficient exposure to the elbow joint and helping to achieve anatomical fracture reduction with the intact olecranon as a template.

Methods: We performed a retrospective review at two trauma centres and identified 31 skeletally mature distal humerus fractures treated with a TRA.

Associated lesions in posterior wall acetabular fractures: not a valid predictor of failure.

Background: The general outcome of posterior wall acetabular fractures is still the source of discussion. Posterior wall fractures are recognized throughout the literature as being difficult to treat. The aim of the present study was to analyze in our own patients the relevance of the classical prognostic criteria for the outcome of isolated posterior wall fractures and those with associated lesions.
