Abstract

OBJECTIVE
Posterior apophyseal ring fracture (PARF) is a common disorder that may be accompanied by herniated lumbar disc (HLD) in patients in their early twenties. However, there are very few reports on PARF in this clinical context. The objective of this study was to identify the incidence and characteristics of PARF with HLD in this age group.
METHODS
We surveyed patients who visited Armed Forces Busan Hospital between May 2017 and October 2017 and included those aged between 19 and 25 years who had HLD accompanied by PARF. We retrospectively collected their demographic characteristics, clinical manifestations, and radiological findings on computed tomography (CT) scans. We categorized the PARF lesions according to Takata's classification.
RESULTS
Of 140 HLD patients, 43 (30.7%) had PARF lesions with HLD. We found that the presence of a PARF lesion was significantly related to a severe pain score on the visual analogue scale for lower back pain and/or lower leg radiating pain (p=0.001). The most common level and location of PARF were L5/S1 (n=25, 56.8%) and the superior endplate of the S1 vertebra, respectively. Type 1, according to Takata's classification, was the most common type of PARF in the patients (n=34, 77.2%).
CONCLUSION
We recommend that spinal surgeons perform CT scans to check for PARF lesions in all young patients in their 20s who present with severe radiating and lower back pain.
