To investigate whether depression symptomatology is associated with low back pain (LBP) in twins aged 70+ and whether this effect depends on a person's physical activity (PA) status. ⋯ High depression symptomatology predicted incident LBP. This effect is supposedly not attributable to genetic or shared environmental factors. Physical activity did not moderate the effect of depression symptomatology on LBP.

Multiple myeloma (MM) and solitary plasmacytoma of bone (SPB) are two independent subtypes of plasma cell dyscrasias which often occur in spine. However, little is known about the surgical treatment of patients with spinal instability or neurological impairment caused by spinal lesions as the first clinical manifestation. The present study aimed to investigate the surgical outcome of these patients. ⋯ Surgery may be beneficial to patients with spinal instability or neurological impairment caused by spinal lesions as the first clinical manifestation, in which MM patients with postoperative ambulatory ability display better prognosis.

A number of anterior reconstruction options are available in patients managed for symptomatic metastatic spinal column disease. Polymethylmethacrylate (PMMA) has been traditionally used as a reconstruction option in patients with limited life expectancy as an anterior fusion is not expected. In this article, we present the outcome of a 13-year follow-up of a long anterior reconstruction using PMMA of the upper thoracic spine in a myelopathic female secondary to a compressive breast metastasis affecting the upper 4 thoracic vertebrae. We discuss the use of PMMA in spinal oncological surgery and review the evidence pertinent to its use.

To clarify the relationship between the laminoplasty opening size (LOS), the laminoplasty opening angle (LOA) and the increase in sagittal canal diameter (SCD) and to predict the amount of canal enlargement during open-door cervical laminoplasty (ODCL). ⋯ Formula accurately showed the relationship between the LOS and the increase in SCD achieved by ODCL. The amount of canal enlargement following ODCL could be predicted by the formula. LOS of 10-12 mm at C3-C7 might be optimal during ODCL.

To clarify the relationship between laminoplasty opening angle (LOA) and the increase in sagittal canal diameter (SCD) in double-door cervical laminoplasty (DDCL) and to predict the increase in SCD using the resulting formula. ⋯ The formula accurately showed the relationship between LOA and the increase in SCD in DDCL. Based on the LOA, increases in SCD following C3-C7 laminoplasty can be accurately predicted using this formula. This enables DDCL based on accurate individual LOAs, which prevents inadequate or excessive opening.
