Surgeon Preferences in Scoliosis Treatment Explored

Preference for implant type was not related to surgical outcomes

FRIDAY, Dec. 7 (HealthDay News) -- Orthopedic surgeons report greater satisfaction with Universal Spine System implants for surgical correction of scoliosis, despite the fact that patient outcomes do not differ between that system and the Moss Miami system, researchers report in the December issue of the Journal of Bone & Joint Surgery.

James G. Wright, M.D., of the Hospital for Sick Children in Toronto, Canada, and colleagues randomized 129 adolescents with idiopathic scoliosis to undergo posterior instrumentation and arthrodesis with or without anterior release using either the Moss Miami system or the Universal Spine System by surgeons familiar with both methods. The researchers assessed patient-reported quality of life using two scales.

Two years postoperatively, quality of life did not differ between the two groups. In addition, thoracic and lumbar curve correction was similar between the two groups. However, surgeons reported greater satisfaction with the Universal Spine System.

"In conclusion, patients' quality of life and the objective outcomes of surgery did not differ between systems, but surgeon preferences did. It is unclear why surgeon preferences differ, but these data suggest that surgeon preference may be an unreliable means of selecting implants from the perspective of patient outcomes," the authors write.

The authors report receiving funding from DePuy AcroMed-Johnson and Johnson Medical Products (manufacturer of the Moss Miami system), and Synthes, Canada (manufacturer of the Universal Spine System).
