Prospective comparison of magnetic resonance imaging and computed tomography in diagnosing occult scaphoid fractures.

Background: Suspected scaphoid fracture (SF) after a fall on an outstretched hand is a common presentation in the emergency department. Magnetic resonance imaging (MRI) or computed tomography (CT) has been suggested to assist in the diagnosis or exclusion of SF.

Purpose: To compare MRI and CT at diagnosing occult SFs.

Spontaneous thigh compartment syndrome.

A young man presented with a painful and swollen thigh, without any history of trauma, illness, coagulopathic medication or recent exertional exercise. Preliminary imaging delineated a haematoma in the anterior thigh, without any fractures or muscle trauma. Emergent fasciotomies were performed.

Use of the Liverpool Elbow Score as a postal questionnaire for the assessment of outcome after total elbow arthroplasty.

The Liverpool Elbow Score (LES) is a newly developed, validated elbow-specific score. It consists of a patient-answered questionnaire (PAQ) and a clinical assessment. The purpose of this study was to determine whether the PAQ portion of the LES could be used independently as a postal questionnaire for the assessment of outcome after total elbow arthroplasty and to correlate the LES and the Mayo Elbow Performance Score (MEPS).

A comparison of the reliability and validity of bone stock loss classification systems used for revision hip surgery.

Three femoral (Paprosky, American Academy of Orthopaedic Surgeons [AAOS], and Endo-Klinik) and 2 acetabular (Paprosky, AAOS) bone stock loss classification systems were evaluated for reliability. Four observers (2 consultants, 2 registrars) graded the bone loss in 25 patients using preoperative radiographs. Grading was repeated after a minimum of 2 weeks.

An in-vitro investigation of the CPS-Plus femoral stem: influence of the proximal centraliser on cement pressurisation during stem insertion.

The CPS-Plus stem is designed for use with a proximal and distal stem centraliser. This in-vitro study examined the cement pressurisation achieved during insertion of the CPS-Plus femoral stem into a model femur. Cement pressures were measured at proximal, mid and distal stem levels.
