Successful Closed Reduction of Atlantoaxial Rotatory Fixation in Children—A Retrospective Study of 30 Patients

Abstract

Study Design: Retrospective cohort study. Objectives: To review our treatment experience and to investigate the process of this disease. Methods: Clinical data of AARF patients, who received closed reduction, was retrospectively reviewed. Patients were divided into 2 groups according to the length of delay (Group I: 1 month ≤ delayed time < 3 months), Group II (delayed time < 1 months). The correlation between the length of delayed time and clinical recovery (CR), radiological recovery (RR), and total recovery time were measured. The atlantodental interval (ADI), lateral mass-dens interval (LDI) and lateral joint space (LJS) were compared at admission and final follow-up. Results: 30 children (12 girls and 18 boys) with AARF had received conservative treatment. The mean age at initial treatment was 8.13-year-old, ranging from 5 to 14. The mean follow-up time was 26.93 months (range, 6-87 months). The average length of delayed time was 28.53 days (range, 2-80 days). When the LDI, LJS, and ADI differences are compared at admission and the final visit, the differences are reduced significantly on LDI and LJS. A positive correlation is observed between the length of the delay and CR time and total recovery time (r = 0.63, p = 0.00 and r = 0.47, p = 0.01) respectively. Conclusions: Pediatric AARF patients who have a delay time < 3 months can be treated with closed reduction successfully. The longer the delayed time, the longer the traction time, but the cervical collar time is almost the same. The LDI and LJS on the anteroposterior of X-rays are convenient to estimate the progress of this condition during the treatment.

Non-Surgical Treatment in Acute and Chronic Grisel’s Syndrome: Two Case Reports and Literature Review

“…The treatment of Grisel's syndrome consists of non-surger-ies, including halter traction, cervical brace and skull traction and surgeries (C1-2 arthrodesis). Patients, who present within 1 month from the onset of symptoms, are routinely treated by non-surgeries like analgesics, cervical collar for comfort 18) . However chronic Grisel's syndrome has been treated with surgery.…”
