Biomechanical Advantages of Novel Duet Screws Plus Bilateral Satellite Rods Fixation in the Correction Surgery for Adult Spinal Deformity

Orthopaedic Surgery, Volume 17, Issue 8, Page 2454-2466, August 2025.
Satellite rods with duet screws in a four‐rod construct significantly decrease rod stress at the L3 PSO and sacrum, reducing rod breakage without compromising spinal motion. Finite element and cadaveric tests confirm this biomechanical advantage for adult spinal deformity surgery with long fusion to the pelvis.

Neurological Evaluation of Severe Congenital Kyphosis With Compressive Myelopathy in 39 Patients With a Minimum 1‐Year Follow‐Up

Orthopaedic Surgery, Volume 17, Issue 7, Page 2004-2014, July 2025.
We suggested that the duration of symptoms and the severity of spinal cord compression were two major contributors to the neurological prognosis in patients with CK. MRI indicators of poor prognosis included the presence of T1WI hypointensity, T2WI hyperintensity, and greater MCC, MSCC, and MTAC.

Selecting the Substantially Touched Vertebra as the Lowest Instrumented Vertebra in Spinal Surgeries for B3GALT6 ‐Related Disorders: Clinical Experience and Literature Review

Orthopaedic Surgery, Volume 17, Issue 7, Page 2025-2037, July 2025.
Selecting the STV as the LIV is recommended in spinal surgeries for patients with B3GALT6‐related disorders, considering the characteristic joint hypermobility associated with the condition. Additionally, preoperative Halo‐pelvic traction may also be safe and effective.

Pedicle Subtraction Osteotomy Construct Optimization: A Cadaveric Study of Various Multirod and Interbody Configurations

, 2022
STUDY DESIGN: Fourteen cadaveric specimens were separated into 2 groups: L3 pedicle subtraction osteotomy (PSO) with TLIF or (2) LLIF. A 2-rod configuration (2R) was compared with 2 supplemental rod configurations: 4-rod (4R) with accessory rods (ARs ...

Late‐Onset Spinal Cord Dysfunction in Rigid Posttraumatic Thoracolumbar Kyphosis: Radiographic Analysis of Neurological Compromise

Orthopaedic Surgery, Volume 17, Issue 7, Page 2048-2056, July 2025.
Three main causes of late‐onset spinal cord dysfunction in rigid posttraumatic thoracolumbar kyphosis: Type I. Compression at the apex (59.0%). Type II. Degenerative thoracic stenosis above the apex (25.6%). Type III. Coexistence of both (15.4%). T10/11 was the most involved site.

Treatment of L5–S1 Spondyloptosis via Posterior‐Only L5 Partial Spondylectomy and Reduction of L4 Onto S1: Surgical Technique and Case Series

Orthopaedic Surgery, Volume 17, Issue 7, Page 2193-2200, July 2025.
Spondyloptosis (Grade‐V spondylolisthesis) is the most severe form of spondylolisthesis and presents significant surgical challenges due to its rarity and complexity. A modified posterior‐only approach technique is reported. Posterior‐only L5 partial spondylectomy with L4–S1 reduction is a feasible and effective treatment for lumbar spondyloptosis ...
