Background:

Recurrent painful locking of the lower back (RPLB) is characterized by sudden, brief episodes of spinal pain without exertion.
This condition presents with episodes resolving within minutes, recurring over weeks or months.

Observation:

A retrospective study analyzed 20 outpatients diagnosed with RPLB between 1978 and 1992.
Patients had a history of lumbago (low back pain) for 10-30 years, with RPLB onset at a mean age of 56.
Female patients constituted 70% of the study group.

Findings:

RPLB onset occurred significantly later than lumbago, indicating more advanced lumbar spine damage.
A potential cause is a mobile flap at the posterior anulus fibrosus.
The majority of patients experienced symptom resolution within six months.

Implications:

RPLB may signify a distinct, later-stage spinal pathology compared to general lumbago.
Understanding the pathophysiology can inform targeted treatment strategies for recurrent low back pain.
Further research into the mobile flap hypothesis could clarify the etiology of RPLB.
