Low back pain injuries enhanced by psychological and social stress

Underlining injuries associated with low back pain are often enhanced by psychological and social stressors, write the authors of a perspective published online by the Medical Journal of Australia.

Leigh Atkinson, from Wesley Pain and Spine Centre in Brisbane, Australia, and Andrew Zacest from Royal Adelaide Hospital (Adelaide, Australia) write that patients often have high expectations from modern medicine, and expect a surgical solution to their back pain.

They explained the high incidence of low back pain in developed countries is best understood in terms of a biopsychosocial framework, in which pain from an injury is compounded by issues such as work dissatisfaction, family stress, depression and, at times, secondary gain.

Often compensation system and third party insurance prolongs rehabilitation and extends recovery. However, a study of patients receiving workers’ compensation in New South Wales, Australia, found surgery outcomes were so poor that the benefits were marginal.

“The incidence of persistent post-operative pain syndrome was as high as 40% and…there was a 50% success rate, at best, from the first operation, 30% from the second and 15% from the third,” the authors explain.

The authors noted a growing tendency for spinal surgeons “to have all patients assessed independently and, at times, for them to attend an interdisciplinary pain program to clarify issues of psychological and social origin”.

They also observed that the increasingly sedentary lifestyles of Australia’s ageing population have further compounded the problem.

“While the spinal fusion procedure remains controversial, it would be valuable for spinal surgeons to undertake a national audit of patient-centred outcomes for the procedure, similar to the excellent audit carried out for hip and knee arthroplasties by the Australian orthopaedic surgeons,” they conclude.
