ANINNOVATIVE BIOMECHANIC TECHNIQUE OF TOTAL HIP ARTHROPLASTY IN SICKLE CELL DISEASED HIP PATIENTS WITH FEMORAL CANAL STENOSIS

Abstract
Improved life expectancy in patients with sickle cell haemoglobinopathies and the improved outcomes of surgical intervention have led to increase in number of patients with osteonecrosis requiring total hip arthroplasties. Both medical and surgical complications of hip arthroplasties provide serious challenges which require optimization of patients to minimise the complications.
As a surgeon operating mainly in West Africa especially with a high number of young patients from (13 years to 56years – average 34 years), femoral canal ‘pencil size’ stenosis has proven to be the greatest challenge to a successful implantation of the smallest implants successfully. Excessive reaming of the femoral canals is associated with bone necrosis and severe femoral bone loss leading to failure of the arthroplasty.
A resolution of this problem requires either the manufacture of smaller implants which risk implant fracture or a novel bio-mechanic osteotomy approach for fixation of a standard smallest cementless implants successfully aimed at achieving satisfactory outcomes for the past 14years.The approach involve longitudinal osteotomy over pre-measured and multiple drilling of the anterior part of the femoral cortex supported by a 3 point stabilization of the femoral with or without cabling. Results to date match that of arthroplasty in non-sicklers which is indeed encouraging
