Case Follow-Up: Severe Sagittal Malalignment Corrected with Pedicle Subtraction Osteotomy
Follow-up on a case of severe lumbar sagittal malalignment treated with T12-pelvis posterior fusion, TLIF at L5-S1, and pedicle subtraction osteotomy at L5. The patient regained the ability to stand upright for the first time in decades.
Cervical Epidural Abscess
An update on a cervical epidural abscess case: Successful partial C4 corpectomy led to significant neurological recovery. The abscess was more phlegmon than liquid. A fibular allograft was used for anterior column reconstruction and stability. Key takeaways: About Dr. Zeeshan SardarDr. Sardar, MD, MSc, F.R.C.S.C, is Co-Chief of Spinal Deformity Surgery at NewYork-Presbyterian / ColumbiaContinue reading “Cervical Epidural Abscess”
How good is AI in Spine?
Is AI good at deciphering spinal intricacies? Take a look at this AI-generated spine image. While it mimics the spine from a distance, the details are off in ways that matter clinically — proportions, anatomical relationships, and structural specifics that a trained eye catches immediately. This reflects a broader truth about AI in medicine: itContinue reading “How good is AI in Spine?”
Spondylolisthesis, stenosis, and lumbar kyphosis
Patients with spondylolisthesis, stenosis, and lumbar kyphosis can have major difficulties with standing upright and with day-to-day function. Realignment and stabilization of the spine can lead to a dramatic improvement in quality of life. The patient shown below was extremely happy postoperatively — she was able to stand upright for the first time in manyContinue reading “Spondylolisthesis, stenosis, and lumbar kyphosis”
Individualized Surgical Planning using the #MEANS concepts
Matching thoracic kyphosis, lumbar lordosis, and pelvic incidence in the sagittal plane is central to optimal alignment in adult spinal deformity surgery. The same principle applies in the coronal plane: the fractional lumbosacral curve, lumbar scoliosis, and thoracic scoliosis must be balanced against each other in the surgical plan. The case below illustrates individualized surgicalContinue reading “Individualized Surgical Planning using the #MEANS concepts”
Spinal alignment varies with an individual’s race !
A Multi-Ethnic Alignment Normative Study (MEANS) Spinal alignment is determined by more than just the PI or SS.We compared individuals from three main races: Asian (A), Arabo-Bèrbère (B), and Caucasian (C). Key points:-Pelvic morphology including pelvic incidence (A: 51.0, B: 52.0, C: 52.5, p = 0.37), pelvic tilt (A: 11.9, B: 12.3, C: 12.9, pContinue reading “Spinal alignment varies with an individual’s race !”
Guidelines for Assessment and Management of Osteoporosis in Adult Patients Undergoing Elective Spinal Reconstruction
Following our work on bone health in adults undergoing spine surgery, here are the best practice guidelines we published for evaluation and treatment of patients with osteoporosis ahead of elective spinal reconstruction. Full citation: Sardar ZM, Coury JR, Cerpa M, DeWald CJ, Ames CP, et al. Best Practice Guidelines for Assessment and Management of OsteoporosisContinue reading “Guidelines for Assessment and Management of Osteoporosis in Adult Patients Undergoing Elective Spinal Reconstruction”
Bone Health treatment before spine surgery
Alignment may be #1 but Bone Health is a close #2 in preventing mechanical failure in patients undergoing adult spinal deformity surgery This study published by us in JBJS shows the significance of medical treatment of osteoporosis prior to adult spinal deformity surgery. Next step is to identify the osteopenic patients who will benefit fromContinue reading “Bone Health treatment before spine surgery”
What is Normal Lumbar Spine Alignment and segmental lordosis ?
A Multi-Ethnic Alignment Normative Study (MEANS) Here is what we learnt for Lumbar segmental alignment and distribution from the MEANS population. Key Points: Equation for predicting L1-L4 lordosis which I use:L1-L4 = -0.4(PI) + 2.2 Equations for predicting L1-S1 lordosis were given in the earlier post. L4-S1 lordosis can be calculated as a difference betweenContinue reading “What is Normal Lumbar Spine Alignment and segmental lordosis ?”
