C1-2 Fixation Approach for Patients With Vascular Irregularities: A Case Report

Geriatric Orthopaedic Surgery & Rehabilitation, 2017
In posterior spinal fusion (PSF), the vertebral artery is most vulnerable to injury at C1-2. C2 pedicle screws are often placed into the dorsomedial isthmus of C2. Alternative techniques include C2 laminar screws and wiring techniques. A 67-year-old male

Intraoperative electromyographic monitoring to optimize safe lumbar pedicle screw placement – a retrospective analysis

BMC Musculoskeletal Disorders, 2017
Background The foremost concern of a surgeon during pedicle screw fixation is safety. Assistive modalities, especially intraoperative electromyographic monitoring (EMG) can function as an essential tool to recognize screw malposition that compromise ...

Mini‐Open Versus Open Transforaminal Lumbar Interbody Fusion in Patients Aged ≥ 75 Years: Perioperative Surgical Burden and Clinical Outcomes

Orthopaedic Surgery, Volume 18, Issue 10, Page 2090-2100, October 2026.
In 172 patients aged ≥ 75 years undergoing TLIF, mini‐open TLIF (MO‐TLIF) reduced perioperative burden (shorter operative time, less blood loss, lower POD3 CK) and enabled faster early pain/function recovery versus open TLIF, while 3–6 month PROMs and 12‐month fusion and satisfaction were comparable.

Rate of pedicle screws misplacement in fluoroscopy-guided thoracolumbar surgeries

Al-Azhar Assiut Medical Journal
Background and aim Pedicle screw misplacement rate ranged from 5 to 41% in the lumbar spine and from 3 to 55% in the thoracic spine. The study aimed to estimate the rate of pedicle screw misplacement and compare it with the rate of others.

Headless Compression Screw Fixation Alone for Lunate Coronal Fractures in Kienböck Disease

Orthopaedic Surgery, Volume 18, Issue 10, Page 2224-2229, October 2026.
The optimal management of Kienböck disease with lunate coronal fractures remains controversial. Previous studies advocated excision of the fractured lunate followed by scaphotrapeziotrapezoidal (STT) fusion or proximal row carpectomy. In this study, headless compression screw alone achieved fracture healing and satisfactory clinical outcomes in ...

Global Alignment and Proportion (GAP) Score in Predicting Mechanical Complications After Long‐Segment Fixation for Chinese Geriatric Patients With Adult Degenerative Scoliosis: A Mid‐Term Comparative Study

Orthopaedic Surgery, Volume 18, Issue 10, Page 2195-2204, October 2026.
In our study, we found that the GAP score could effectively predict the risk of mechanical complications after long‐segment fixation surgery in geriatric ADS patients. ABSTRACT Objectives The predictive value of the global alignment and proportion (GAP) score in the Chinese geriatric population, which has unique demographic and degenerative ...

Dorsal C1–2 Spinal Cord Compression After Reduction of Atlantoaxial Posterior Dislocation Associated With Os Odontoideum: A Case Report and Literature Review

Orthopaedic Surgery, Volume 18, Issue 10, Page 2269-2275, October 2026.
Successful reduction of os odontoideum‐associated atlantoaxial posterior dislocation may not always guarantee adequate C1–2 canal space. In patients with congenital atlas hypoplasia or posterior arch osteophytes, postreduction dorsal cord compression should be anticipated, and C1 posterior arch decompression may be required to prevent neurological ...
