Introduction: Hip and knee osteoarthritis (OA) and low back pain (LBP) are prevalent diseases that can negatively impact daily activities. The concurrent existence of lumbar spine disorders with hip or knee issues forms two syndromes: hip-spine syndrome (HSS) and knee-spine syndrome (KSS). The primary objective of this study is to evaluate the relationship between hip and knee OA and LBP, as well as the changes to LBP after total hip arthroplasty (THA) and total knee arthroplasty (TKA).

Article Synopsis
  • The article analyzes how growth impacts spinal and rib cage deformities, particularly focusing on adolescent idiopathic scoliosis (AIS) and the role of the rib cage in this condition.
  • It discusses the genetics and epigenetics associated with AIS, and a novel field of research exploring how nighttime sleep affects the progression of scoliosis.
  • The author argues that changes in vertebral growth during the development of idiopathic scoliosis are secondary effects of uneven loads on the spine, rather than primary issues within the vertebral bodies themselves.

The aim of this report is to evaluate the segmental rib index (RI) from the T1 to T12 spinal levels in mild and moderate idiopathic scoliosis (IS) curves of thoracic, thoracolumbar and lumbar type by gender. The relationship of segmental RI to the frontal plane radiological deformity presented as the Cobb angle and to the posterior truncal surface deformity presented as the scoliometric readings of Angle of Trunk Rotation (ATR) in these patients is also assessed. Any statistically significant relationship between these parameters would be very important for biomechanical relations in rib cage (RC) deformity presented as rib hump deformity (RHD) and deformity in the spine, and would thus provide valuable information about scoliogeny.

Article Synopsis
  • - The report reviews literature on the postoperative correction of rib hump (RH) following spinal surgery for adolescent idiopathic scoliosis (AIS), emphasizing the importance of clinical monitoring over initial radiographic results in younger children with rib asymmetry, even if they are not scoliotic.
  • - It stresses the significance of using the rib index (RI) derived from spinal radiographs to select the optimal rib level for costoplasty, which is the surgical approach to correct RH, reflecting the necessity for better planning in surgeries.
  • - Findings indicate that while spinal surgery improves curvature, RH correction is often insufficient and may worsen over time, particularly in younger patients, due to the primary cause of RH being rib asymmetry rather than spinal rotation; thus

A sexual dimorphism (SD) of the "vertebra prominens" was found, namely the 7th cervical vertebra (C7) spinous process (SP) is more frequently longer in men and the 1st thoracic (T1) SP in women.[1] We assume that the cause of this SD is the different anatomy of the anterior upper thoracic region (AUTR) between men and women, due to the presence of the breast. One-hundred forty-two women aged 48.

Article Synopsis
  • Patients with osteoarthritis (OA) of the hip and knee show significant changes in spinal and pelvic morphology compared to a control group, with indicators of increased imbalance and curvature.
  • The study included 34 hip OA patients, 45 knee OA patients, and 25 control subjects, highlighting the need for further research on the structural impacts of OA.
  • Results indicate that OA affects patients' postures, leading to a greater forward lean of the spine and increased scoliosis, which could have clinical implications for treatment and patient management.

The fractures of the first cervical spine vertebrae (atlas) represent 7% of all the overall cervical spine fractures. Hypoplasia of the vertebral artery is also rare (10% of the general population), but even rarer is the combination of those both conditions. This combination should always be identified and treated because sometimes it can be extremely dangerous for the patient.
