Orthopedic complications of solid-organ transplantation.
ABSTRACT Organ transplantation has undeniably increased the longevity and quality of life of patients with end-stage organ failure. Its has, however, introduced the skeletal complications of (1) fragility fractures and decreased bone density due to pretransplant bone loss and immunosuppressive therapy, and (2) avascular necrosis leading to subchondral fracture and secondary osteoarthritis. This article reviews these two skeletal complications of solid-organ transplantation that lead to structural failure of bone and result in significant morbidity and reduced quality of life.

ABSTRACT: As the survival rate of the intestinal and multi-visceral transplant recipients continues to improve, an increasing number of these patients present for either elective or emergency surgery related or unrelated to transplantation. The aim of this review is to focus on clinical issues related to the anesthetic and perioperative management of the intestinal or multi-visceral transplant recipient for nontransplant surgery. Specific issues concerning perioperative assessment and medications, choice of anesthetic drugs and techniques, and postoperative care management are reviewed.Transplant International 06/2008; 21(5):415-27.

ABSTRACT: Despite the increasing success of transplantation, graft recipients experience a high burden of musculoskeletal symptoms that may hinder quality of life. Post-transplant musculoskeletal problems may result from sequelae of the organ dysfunction that indicated the transplant or from the subsequent anti-rejection therapy. Rheumatology consultants need to be familiar with the spectrum of musculoskeletal syndromes presenting in these unique patients and their appropriate treatment in the context of complex drug regimens and immunosuppression.Best practice & research.

ABSTRACT: In Australia, benefits for antifracture therapies have been available for patients with osteoporosis and a prior fracture. No benefits were available to those with no prior fracture. We aimed to define, in women with no prior fracture, age-related thresholds of bone mineral density (BMD) associated with fracture risk equivalent to that of women with prior fracture and osteoporosis. A case-control study of women (> or =50 yr) was conducted, including 291 fracture cases and 823 controls. BMD was measured at the proximal femur and posterior anterior (PA) spine. A fracture risk score (FRS) for the group with no prior fracture was calculated with discriminant analysis. The thresholds for equivalent fracture risk between those with no prior fracture and those with prior fracture were assessed using logistic regression. Increasing the FRS to +0.98 in women with no prior fracture resulted in equivalent odds of sustaining a fracture to those with prior fracture and osteoporosis. The corresponding T-score thresholds at the spine were -4.6 at 50 yr, -3.9 at 60 yr, -3.1 at 70 yr, and -2.4 at 80 yr. The femoral neck T-score thresholds were lower by 0.5 standard deviation. The high-risk individuals defined by this study should be considered for primary fracture prevention therapy.Journal of Clinical Densitometry 07/2008; 11(4):494-7.
