Mixed manufacturer dual mobility bearing and the Exeter V40 Stem: is it safe? Short-term results in primary and revision hip replacement.

The aim is to review clinical and radiological outcomes for all cases of primary and revision THA, combining a cemented stem (Exeter V40) with a dual mobility component from a different manufacturer (SERF Novae), to evaluate whether concerns regarding mixing components from different manufacturers are justified. We identified 72 hip replacements performed between May 2010 and December 2015 using the SERF Novae dual mobility cup with an Exeter V40 stem, the majority of which were cemented (90%) and revisions (58%). Patients were evaluated clinically and radiologically at a minimum of two years.

Dual-mobility bearings in complex revision hip arthroplasty.

Background: Revision total hip arthroplasty (rTHA) is associated with an increased dislocation risk. Dual-mobility (DM) bearings have been used to address this issue. Such constructs offer increased range of motion and enhanced stability whilst avoiding some issues associated with fully-constrained devices.

Combined fluoroscopic and ultrasound guided cervical nerve root injections.

Purpose: To assess the technical feasibility, safety and initial clinical efficacy of a combined ultrasound and fluoroscopy imaging approach to cervical nerve root blocks. Fluoroscopic guided cervical transforaminal and selective nerve root injections are often used in the investigation or treatment of radicular symptoms, although rare but serious complications including death have been reported. We report a combined technique developed to increase safety of selective nerve root injections, including the safety and early efficacy of this novel technique in our initial patient cohort.

Judet osteoperiosteal decortication for treatment of non-union: the Cornwall experience.

Background: The treatment of non union can be challenging with a variety of surgical options available to achieve bone consolidation. Robert Judet first described a method of osteo-periosteal decortication in 1963. He stated that by elevating cortical chips that remain attached to the periosteum and overlying soft tissues surrounding the site of non-union, combined with mechanical support, the bone consolidated.

Hip resurfacing arthroplasty in patients with varus deformity of the femoral neck-shaft angle.

Hip resurfacing arthroplasty (HRA) in patients with a varus deformity of the femoral neck-shaft angle (NSA) is associated with poorer outcomes. Our experience has not reflected this. We examined the Oxford Hip Scores (OHS), Harris Hip Scores (HHS) and outcomes of patients with varus hips against a normal cohort to ascertain any significant difference.
