Bracing Adolescent Idiopathic Scoliosis (BASIS) study - night-time versus full-time bracing in adolescent idiopathic scoliosis: study protocol for a multicentre, randomized controlled trial.

Aims: Scoliosis is a lateral curvature of the spine with associated rotation, often causing distress due to appearance. For some curves, there is good evidence to support the use of a spinal brace, worn for 20 to 24 hours a day to minimize the curve, making it as straight as possible during growth, preventing progression. Compliance can be poor due to appearance and comfort.

Cauda equina syndrome.

Aims: Patients with cauda equina syndrome (CES) require emergency imaging and surgical decompression. The severity and type of symptoms may influence the timing of imaging and surgery, and help predict the patient's prognosis. Categories of CES attempt to group patients for management and prognostication purposes.

Presentation, management, and outcomes of cauda equina syndrome up to one year after surgery, using clinician and participant reporting: A multi-centre prospective cohort study.

Background: Cauda equina syndrome (CES) results from nerve root compression in the lumbosacral spine, usually due to a prolapsed intervertebral disc. Evidence for management of CES is limited by its infrequent occurrence and lack of standardised clinical definitions and outcome measures.

Methods: This is a prospective multi-centre observational cohort study of adults with CES in the UK.

Study protocol for a randomised controlled trial of consenting processes and their effects on patient decision-making when undergoing spinal injections: the Risks In Spinal Consenting for Surgery (RISCS) trial.

Introduction: There are major differences between legal and medical approaches to informed consent. Medically, consent is obtained prospectively for an intended procedure, to inform the patient of choices, risks and benefits, and to manage expectations. Legally, consent is reviewed retrospectively, usually following unmet expectations and/or the occurrence of complications.

Caution: laparoscopic biopsy of a large pelvic mass may result in disaster.

Anterior sacral meningocele is a rare cause of a pelvic mass. Herein the authors describe the case of a young patient presenting with chronic pelvic pain undergoing diagnostic laparoscopy. She was found to have a retrorectal mass confirmed as an anterior sacral meningocele on subsequent MRI.

Avulsion of the perforating branch of the peroneal artery secondary to an ankle sprain: a cause of acute compartment syndrome in the leg.

In this report, we describe the case of an adult male who developed an acute compartment syndrome localized to the anterior compartment of the leg following an ankle sprain. Compartment syndrome in association with ankle sprain is unusual, and has been previously described in association with avulsion of the perforating peroneal artery. Because of the potential for severe morbidity, we feel that it is important to make foot and ankle surgeons aware of this unusual injury.

The use of physical biomodelling in complex spinal surgery.

Prior studies have suggested that biomodels enhance patient education, preoperative planning and intra-operative stereotaxy; however, the usefulness of biomodels compared to regular imaging modalities such as X-ray, CT and MR has not been quantified. Our objective was to quantify the surgeon's perceptions on the usefulness of biomodels compared to standard visualisation modalities for preoperative planning and intra-operative anatomical reference. Physical biomodels were manufactured for a series of 26 consecutive patients with complex spinal pathologies using a stereolithographic technique based on CT data.

In vivo temperature profile of intervertebral discs and vertebral endplates during vertebroplasty: an experimental study in sheep.

Study Design: Experimental study of temperature profiles during vertebroplasty.

Objectives: To define accurate temperature profiles during vertebroplasty in an in vivo animal model.

Summary Of Background Data: Controversy still exists whether vertebroplasty achieves its analgesic effect by stabilizing fracture fragments or due to thermal damage of sensory nerves inside the vertebral body.

Racing prognosis of horses following surgically repaired olecranon fractures.

Olecranon fracture is a common orthopedic problem in juvenile horses. Prognosis for complete fracture healing when various methods of internal fixation are used is good; however, the impact of olecranon fracture stabilization on the likelihood that foals will start on a racecourse is unknown. Medical records of foals undergoing internal fixation for an olecranon fracture were reviewed.

A lag-screw technique for bridging of the medial aspect of the distal tibial physis in horses.

A lag-screw technique for transphyseal bridging of the medial aspect of the distal tibial physis in foals with tarsal valgus deformities and results of the technique in 11 foals (6 with bilateral tarsal valgus deformities and 5 with unilateral tarsal valgus deformities) are described. Briefly, horses were anesthetized, and a single stab incision was made through the skin to the underlying bone over the most distal aspect of the medial malleolus. A 20-gauge needle was placed in the incision to guide screw placement, and a lag screw was inserted parallel to the medial cortex of the tibia under radiographic guidance.
