Overview
Spine at a glance
Spine practice spans degenerative disease, deformity, trauma, infection and tumour. The subspecialty has moved decisively toward tissue-sparing access, navigation and objective patient-reported outcome tracking.
This hub collects operative decision-making, technique detail, device evolution and peer research contributed by the OrthoNexus community.
Common conditions
Presentations that dominate the clinic and emergency workload in this subspecialty.
Lumbar disc herniation
Radicular pain with dermatomal deficit; most resolve non-operatively within 8–12 weeks.
Lumbar canal stenosis
Neurogenic claudication in the older adult, often with degenerative spondylolisthesis.
Cervical myelopathy
Progressive cord compression presenting with gait and fine-motor decline.
Adolescent idiopathic scoliosis
Curve progression assessed against skeletal maturity and Cobb angle.
Osteoporotic vertebral fracture
Fragility fracture requiring bone-health workup alongside pain control.
Procedures
Core operative procedures, from day-care work to complex reconstruction.
Microdiscectomy
Tubular or open microscope-assisted removal of the offending disc fragment.
Laminectomy and decompression
Central and lateral recess decompression, with or without fusion.
TLIF / PLIF
Interbody fusion for instability, deformity or recurrent stenosis.
Anterior cervical discectomy and fusion
Workhorse for one- and two-level cervical radiculopathy.
Posterior deformity correction
Pedicle-screw constructs with osteotomies for rigid curves.
Surgical techniques
Technical detail and decision points discussed by faculty in this hub.
Tubular retractor access
Sequential dilation preserving the multifidus attachment and reducing blood loss.
Freehand vs navigated pedicle screws
Anatomic landmarks compared against 3D navigation and robotic guidance.
Ponte and pedicle subtraction osteotomy
Correction power matched to the rigidity and apex of the deformity.
Neuromonitoring discipline
MEP/SSEP checkpoints and a rehearsed response protocol for signal loss.
Latest innovations
Devices, workflows and technology changing how this subspecialty is practised.
Augmented-reality screw guidance
Head-mounted overlays reducing fluoroscopy exposure in percutaneous fixation.
Expandable interbody cages
In-situ height restoration with smaller annulotomy footprints.
Endoscopic uniportal decompression
Day-care spinal decompression with early ambulation pathways.
Research
Community research threads currently active in this specialty.
PROM registry for lumbar fusion
Two-year ODI and VAS trajectories across a multi-centre demo cohort.
Erector spinae plane block
Opioid-sparing effect after posterior instrumentation.
Sagittal balance predictors
Pelvic incidence–lumbar lordosis mismatch and revision risk.
Thesis
Postgraduate thesis work shared with the community.
Endoscopic vs microscopic discectomy
Comparative outcomes and learning-curve analysis in a residency setting.
Vitamin D status in fragility spine fractures
Prospective observational thesis across an urban–rural catchment.
