The effect of surgical approach on the histologyof the femoral head following resurfacing of the hip: Analysis of retrieval specimens.

Objectives: We aimed to determine the effect of surgical approach on the histology of the femoral head following resurfacing of the hip.

Methods: We performed a histological assessment of the bone under the femoral component taken from retrieval specimens of patients having revision surgery following resurfacing of the hip. We compared the number of empty lacunae in specimens from patients who had originally had a posterior surgical approach with the number in patients having alternative surgical approaches.

Scintigraphic assessment of bone status at one year following hip resurfacing: Comparison of two surgical approaches using SPECT-CT scan.

Objectives: To study the vascularity and bone metabolism of the femoral head/neck following hip resurfacing arthroplasty, and to use these results to compare the posterior and the trochanteric-flip approaches.

Methods: In our previous work, we reported changes to intra-operative blood flow during hip resurfacing arthroplasty comparing two surgical approaches. In this study, we report the vascularity and the metabolic bone function in the proximal femur in these same patients at one year after the surgery.

SPECT/CT bone imaging after hip resurfacing arthroplasty: is it feasible to use CT attenuation correction in the presence of metal implants?

Background: In hip resurfacing arthroplasty a metal implant (prosthesis) is used to resurface the patient's native femoral head. The assessment of bone function around the implant is important in evaluating any subsequent complications. The use of bone single photon emission computed tomography/computed tomography (SPECT/CT) imaging may enhance this evaluation.

The blood flow to the femoral head/neck junction during resurfacing arthroplasty: a comparison of two approaches using Laser Doppler flowmetry.

We used Laser Doppler flowmetry to measure the effect on the blood flow to the femoral head/neck junction of two surgical approaches during resurfacing arthroplasty. We studied 24 hips undergoing resurfacing arthroplasty for osteoarthritis. Of these, 12 had a posterior approach and 12 a trochanteric flip approach.

A case of eosinophilic meningitis.

A case of eosinophilic meningitis is reported, a condition not previously reported from Sri Lanka. We propose Angiostrongylus cantonesis to be the most likely causative agent in this patient.
