Introduction:
This study investigates the outcomes of treating neglected unstable Hangman's fractures through a single-stage Anterior Cervical Discectomy and Fusion (ACDF) procedure with tricortical iliac crest bone grafts.
Methods:
Five patients with neglected unstable Hangman's fractures, treated at our institution between March 2012 and March 2017, underwent C2-C3 ACDF. Functional outcomes were assessed using the Visual Analog Scale (VAS) score and Neck Disability Index (NDI), and neurological evaluation was done using the American Spinal Injury Association (ASIA) grading system. The radiological assessment included serial plain radiographs and a computed tomography scan at a 12-month follow-up.
Results:
Postoperatively, C2-C3 angulation improved significantly, decreasing from 15° to 4.4°, and sagittal translation improved from 4.2 mm to 2 mm. The VAS score improved from 6.4 to 1.4 at 24 months postsurgery. Concurrently, NDI decreased from 70.4% to 14.8%. Fusion occurred in an average of 5.6 months. Neurologically, one patient improved from ASIA grade D to grade E, while the other four retained their grade E status.
Conclusions:
A single-stage ACDF with autologous iliac crest bone grafts is an effective surgical option for neglected type II/IIA Hangman's fractures, yielding satisfactory functional and radiological outcomes. This technique significantly corrects anterior translation and angulation, even in neglected cases, with the aid of intraoperative skull traction and plate reduction.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
