AI Article Synopsis
- The study involved 60 patients with confirmed discogenic pain who were randomly assigned to either BAK anterior interbody fusion or SB Charité artificial disc replacement, focusing on degenerative disc disease.
- The average age of participants was 40.3 years, with most cases located at L4-L5 and L5-S1, and both surgical procedures took an average of about 88.4 minutes.
- Results showed significant improvement in the Oswestry Disability Index scores for those receiving the SB Charité disc replacement, indicating comparable effectiveness to traditional lumbar fusion methods.
Article Abstract
Sixty patients with one-level discogenic pain confirmed by plain radiography, magnetic resonance imaging, and provocative discography for degenerative disc disease were randomized: one-third BAK anterior interbody fusion and two-thirds anterior SB Charité artificial disc replacement. The mean age was 40.3 years (range 21-56 years). Nineteen cases were at L4-L5 and 41 cases were at L5-S1. Nineteen cases had BAK anterior interbody fusion and 41 cases were randomized as SB Charité disc replacement. The length of surgery was mean 88.4 minutes (range 54-137 minutes) for both groups. The estimated blood loss was mean 289.5 mL (range 50-1800 mL). The length of hospital stay was a mean of 3.03 days (range 2-6 days). Oswestry Disability Index scores for the SB Charité disc (aggregate study group) were 50.0 +/- 14.3 preoperatively and 25.0 +/- 20.1 at 1-3 years' follow-up (P < 0.001). This is the first study that shows improvement of functional outcome measures in a prospective randomized design with disc arthroplasty treating primarily mechanical back pain and achieving comparable successful results to lumbar fusion-interbody fusion cage and BMP or interbody autograft and pedicle screw instrumentation.

Anterior cervical discectomy and fusion with self-locking standalone cage for the treatment of cervical degenerative disc disease in patients over 80 years.
J Orthop Traumatol

Department of Orthopaedic Surgery, Zhongshan Hospital, Fudan University, 180 Fenglin Road, Shanghai, 200032, China.
Background: The need for anterior cervical discectomy and fusion (ACDF) for cervical degenerative disc disease (CDDD) will probably grow dramatically in the geriatric population. However, ACDF with self-locking standalone cages in patients over 80 years has not yet been investigated. This study aimed to assess the clinical and radiographic results in patients over 80 years treated by ACDF with self-locking standalone cages.

Purpose: To evaluate the efficacy and complications of simplified graded inferior oblique anterior transposition (IOAT) in treating at least 10 PD vertical deviation in the primary position and inferior oblique muscle overaction (IOOA).
Methods: This retrospective study reviewed the medical records of 65 patients treated with simplified graded IOAT procedures for both vertical deviation and IOOA. Patients were grouped according to vertical deviation in the primary position.

Low back pain is common in women, especially during pregnancy and puerperium. Septic sacroiliitis, a rare cause of back pain in the postpartum period can mimic other common causes of low back pain like muscle strain, urinary tract infection, pelvic inflammatory disease, endometritis and intervertebral disc prolapse. The proximity of the sacroiliac joint to the sacral nerve plexus results in septic sacroiliitis frequently presenting with symptoms mimicking intervertebral disc prolapse.
