AI Article Synopsis

  • A case report presented a successful series of spinal osteotomies on a patient with severe kyphotic deformity due to ankylosing spondylitis.
  • The 48-year-old male patient had a significant "chin-on-pubis" deformity and underwent multiple surgical interventions, including hip arthroplasties and spinal osteotomies in various regions of the spine.
  • Results showed significant improvement in spinal alignment and daily living activities, achieving remarkable correction angles without complications, marking a pioneering approach in this type of surgery.

Article Abstract

Study Design: A case report.

Objective: To report the successful consecutive spinal osteotomies of multiple segments performed on a patient with extremely severe kyphotic deformity.

Summary Of Background Data: There have been no reports on the experience and surgical strategy of spinal osteotomy on multiple segments for severe global spine deformity.

Methods: A 48-year-old man, a patient with ankylosing spondylitis with "chin-on-pubis" deformity, underwent consecutive spinal osteotomies to correct the severe, fixed global kyphosis. The axial skeletons from the skull, all vertebrae, and both sacroiliac joints and hip joint were fused into a single bone. After both hip resectional arthroplasties for the first step, staged, sequential spinal osteotomies, including pedicle subtraction osteotomy (PSO) on C6, posterior vertebral column resection on T11-T12, and PSO on L3, were performed. Finally, both total hip arthoroplasties were performed.

Results: The chin-brow vertical angle improved from 140° to 15°. Correction angles of 45°, 70°, and 30° in the cervical, thoracic, and lumbar spines, respectively, were achieved without complication. At the last follow-up, excellent improvement in activities of daily living and horizontal gaze were achieved.

Conclusion: This is the first report on C6 PSO and spinal osteotomies in whole spine segments. For patients with a severe global kyphotic deformity, it is important to place the patient in a stable prone position so that corrective surgery can be performed on the thoracolumbar spine. To accomplish this, initially correcting the deformities in the hip joints and the cervical spine can yield excellent clinical results.

Background: Kyphotic spinal deformity is a complication of ankylosing spondylitis (AS). In rare cases, particularly in obese patients, the deformity might extend to the cervicothoracic spine, resulting in a severe "chin-on-abdomen" deformity. This condition severely impairs quality of life by affecting gaze, swallowing, and causing chronic pain.

A posterior trans-intervertebral osteotomy with anterior support for kyphosis deformity secondary to ankylosing spondylitis: a technical note.

BMC Musculoskelet Disord

Department of Orthopedic Surgery, Beijing Chao-Yang Hospital, Capital Medical University, GongTiNanLu 8#, Chaoyang District, Beijing, 100020, China.

Background: This study aimed to assess the efficacy of a novel spinal osteotomy technique, the posterior trans-intervertebral osteotomy with anterior support, in individuals diagnosed with ankylosing spondylitis. This study utilized computer software to simulate the osteotomy procedure, predict orthopedic outcomes, and assist in preoperative planning.

Methods: Four patients with ankylosing spondylitis underwent posterior trans-intervertebral osteotomy with anterior support that post-operative follow-up of more than 1 year.

Study Design: Retrospective cohort study OBJECTIVES: The purpose of this study was to compare the 2-year radiological outcome and revision rates in patients with ASD treated with either PSO or PLIF, when PLIF was used to improve sagittal balance.

Methods: In 2016, PLIF was introduced at our institution as an alternative method when restoring lumbar lordosis. We analyzed two cohorts of patients with ASD undergoing either: PSO in 2010-2015 or PLIF in 2016-2020, retrospectively.

Objective: The objective of this study was to compare a multiple pelvic screw fixation strategy (dual bilateral 4 pelvic screw fixation [4PvS]) with the use of single bilateral 2 pelvic screw fixation (2PvS), with the aim of addressing lumbosacral junction stability.

Methods: This analysis is a single-center, retrospective review of ASD patients treated between 2015 and 2021. All patients had a minimum 2-year follow-up and spinal fusion to the sacrum without sacroiliac fusion and met at least one radiographic and procedural criterion: pelvic incidence-lumbar lordosis ≥ 20°, T1 pelvic angle ≥ 20°, sagittal vertical axis ≥ 7.
