The hidden asymmetry: facet joint tropism as a clue to spinal malalignment and muscle degeneration in adult spinal deformity.

Objectives: The role of facet joint tropism (FJT) in degenerative spinal disorders such as disc herniation, spondylolisthesis, and lumbar canal stenosis is well-established. However, its association with adult spinal deformity (ASD) remains underexplored. Hence, we aim to study the correlation of FJT with spinopelvic parameters and lumbar paraspinal muscle morphology in ASD patients.

A magnetic resonance imaging-based morphometric analysis of bilateral L1-L5 oblique lumbar interbody fusion corridor: feasibility of safe surgical approach and influencing factors.

Study Design: Retrospective cross-sectional study.

Purpose: To investigate the size and local anatomy of the right and the left-sided oblique corridors between L1-L5 levels and identify the potential impact of increasing age and sex on corridor size.

Overview Of Literature: The oblique lumbar interbody fusion (OLIF) was introduced by Silvestre and his colleagues as a solution to the approach-related complications associated with anterior lumbar interbody fusion and lateral lumbar interbody fusion.

Accelerometer-based, hand-held navigation for improved knee alignment in total knee arthroplasty: An observational study.

Background: Malalignment in total knee arthroplasty has been associated with poor implant longevity and clinical outcomes. The aim of this study was to investigate the accuracy of accelerometer-based navigation in restoring the mechanical axis.

Methods: 106 primary total knee arthroplasties performed during February 2016 to September 2017 at a tertiary care centre in India were enrolled in this observational study.

Variations in the Number of Thoracic and Lumbar Vertebrae in Patients With Adolescent Idiopathic Scoliosis: A Retrospective, Observational Study.

Background: Abnormal anatomy is a contributory factor to wrong-level surgery. Variations in the number of vertebrae in populations from different races and geographical regions have been described. A ∼10% prevalence of variations in number of thoracic and lumbar vertebrae in adolescent idiopathic scoliosis (AIS) patients has been previously reported.

Result of delayed repair of quadriceps muscle following a sharp cut injury.

We herewith report a case of a 22-year-old man who suffered from a transverse laceration of the quadriceps muscle. The patient presented to us after 3 months of the injury with an inability to extend the knee. We undertook a surgical repair of the muscle tear using the modified Mason-Allen technique and a polypropylene mesh augmentation.

Oncogenic osteomalacia due to phosphaturic mesenchymal tumour in the upper thoracic spine.

Oncogenic osteomalacia (OO) is an uncommon paraneoplastic syndrome occurring due to the presence of a tumour that oversecretes fibroblast growth factor-23, which impairs renal phosphate handling. In most cases, the tumour is a morphologically distinct entity called 'phosphaturic mesenchymal tumour' (PMT). Spinal tumours causing OO are exceedingly rare.
