Proximal junctional kyphosis and rates of fusion following posterior instrumentation and spinal fusion for adolescent idiopathic scoliosis.

Background: Proximal junctional kyphosis (PJK) can cause significant functional impairment and neural compression. Varying rates of PJK and pseudoarthrosis following posterior instrumentation and fusion for adolescent idiopathic scoliosis (AIS) are described with multiple biologic and biomechanical correlations attributed. This retrospective study aims to determine our rate of pseudoarthrosis and PJK in posterior spinal fusion for AIS, along with analysing the influence of autograft and allograft bone volume.

Functional outcome of matrix-associated autologous chondrocyte implantation in the ankle.

Background: The technique of Matrix-associated autologous chondrocyte implantation (MACI) is well established with satisfactory outcomes up to 5 years in the knee. Fewer series describe the outcomes of this technique in the ankle. We present the functional outcomes of the technique for a single surgeon series in a general hospital setting.

Comparison of two intraoperative assessment methods for injuries to the ankle syndesmosis. A cadaveric study.

Background: Intraoperative stress testing is required for the detection of syndesmosis instability following an ankle fracture. The present study compared two stress tests for the detection of syndesmotic injury.

Methods: A true mortise radiograph of the ankle was made for fourteen cadaver joints.
