Background: Congenital absence of the lumbosacral facet joint is extremely rare, with only 26 cases reported in the literature. Here, we present a patient with the unilateral absence of the left fifth lumbar inferior articular process and reviewed the relevant literature. Case Description: A 32-year-old gentleman, who had undergone right L4-5 lumbar microdiscectomy 3 months ago now presented with acute low back and left leg pain following a fall. He is now presented with acute low back and left leg pain following a fall. Plain radiographs of the L-S spine revealed an absent left L5–S1 zygapoph

<strong>Abstract</strong> This case report describes a rare congenital absence of the L5-S1 lumbosacral articular facet joint and S1 superior articular facet on the left side in a 17-year-old male presenting with lower back pain. Despite being asymptomatic in most cases, this anomaly was diagnosed through a CT scan, highlighting the importance of advanced imaging for accurate diagnosis. Awareness of such rare congenital defects is crucial for proper management of unexplained lower back pain.

Abstract:

A congenital absence of the lumbar facet joint is a rare reported condition. This is the case of a 32-year-old male patient presenting with severe low back pain radiating to his right lower limb. Physical examination revealed no motor deficits, but right lower limb numbness was reported over dorsum aspect of the right foot. No other sensory or motor disturbances were reported or found on exam. Imaging studies, consisting of a spine MRI and spine CT scan with 3D reconstruction, revealed the absence of the right L5-S1 zygapophyseal joint. The patient was treated conservatively with resolution of

Intra-articular fluoroscopically-guided facet joint (FJ) blocks are performed with diagnostic-therapeutic aims, whereas the main focus of ultrasound guided peri-facet joint blocks (USG-PFJB) is pain relief. USG-PFJB will therefore typically utilize higher injection volumes to potentially offer injection spread to other pain-generating structures. This study explores the potential role of USG-PFJBs in the outpatient management of chronic low back pain with our without leg symptoms in patients with MRI-confirmed mild to severe lower lumbar FJ arthrosis.

The aim of this paper is to develop, calibrate, and validate a novel passive hybrid FE-MB open-access simulation model of a ligamentous LSS using ArtiSynth.
