AgreementModerate agreement

Most discussions acknowledge the importance and validity of the new classification, with some expressing surprise or appreciation.

InterestModerate interest

Participants show moderate interest, noting the focus on variations in spinal alignment and the identification of a new type.

EngagementModerate engagement

Posts reflect thoughtful engagement through technical discussions, such as analyzing pelvic incidence and lumbar parameters, and referencing the significance of the new findings.

ImpactModerate impact

The discourse indicates recognition of the study's potential influence on understanding sagittal spine anatomy and clinical approaches, though not universally transformative.

Abstract in brief

  • The study explores how the Roussouly classification of spinal alignment applies to 296 healthy, asymptomatic adults, focusing on variations in pelvic and lumbar parameters, including the concept of anteverted pelvis, which hadn't been studied in this group before.
  • Findings show that although these adults maintained overall balance, their spinal and pelvic features varied significantly across the five Roussouly types; notably, a new type (Type 3 AP) was identified, characterized by low or negative pelvic incidence and hyperlordosis.
  • Most participants had their C7 plumb line behind the hip axis, but a notable portion had it positioned in front, revealing diversity in sagittal alignment even among symptom-free individuals.

Roussouly classificationの再考 何度読んでも混乱します. Type3 Anteverted は,臼不全による二次性股OAの方でうまく代償できている?人によくみられる気がしますが,良いのか,悪いのか.. 動的姿勢を解釈するためにも静的姿勢のポイントは把握したいものです. https://t.co/Ts5f7r8z2R
