An experimental piglet model induces avascular necrosis (AVN)
and deformation of the femoral head but its secondary effects on
the developing acetabulum have not been studied. The aim of this
study was to assess the development of secondary acetabular deformation
following femoral head ischemia. Intracapsular circumferential ligation at the base of the femoral
neck and sectioning of the ligamentum teres were performed in three
week old piglets. MRI was then used for qualitative and quantitative
studies of the acetabula in operated and non-operated hips in eight
piglets from 48 hours to eight weeks post-surgery. Specimen photographs and
histological sections of the acetabula were done at the end of the
study. Objectives
Methods
To review the systemic impact of smoking on bone healing as evidenced
within the orthopaedic literature. A protocol was established and studies were sourced from five
electronic databases. Screening, data abstraction and quality assessment
was conducted by two review authors. Prospective and retrospective
clinical studies were included. The primary outcome measures were
based on clinical and/or radiological indicators of bone healing.
This review specifically focused on non-spinal orthopaedic studies.Objectives
