Robot-Assisted Screw Fixation Combined With Endoscopic Bone Graft in the Minimally Invasive Treatment of Lumbar Spondylolysis: A Single-Center Retrospective Study. [PDF]

Orthop Surg
This study introduces a minimally invasive technique for lumbar spondylolysis, combining robot‐assisted percutaneous screw fixation with endoscopic bone graft. The approach aims to enhance postoperative recovery and patient compliance, offering a valuable alternative to conventional open surgery with potential benefits in terms of precision and reduced

Spondylolysis

Orthopedic Reviews, 2022
Spondylolysis is a bony defect of the pars interarticularis and most often results from repetitive stress. Although spondylolysis is usually asymptomatic, symptomatic spondylolysis is the most common cause of identifiable back pain in children and adolescent athletes.

Deep-Learning-Aided Evaluation of Spondylolysis Imaged with Ultrashort Echo Time Magnetic Resonance Imaging

Italian National Conference on Sensors, 2023
Isthmic spondylolysis results in fracture of pars interarticularis of the lumbar spine, found in as many as half of adolescent athletes with persistent low back pain. While computed tomography (CT) is the gold standard for the diagnosis of spondylolysis,

L5 spondylolysis: Anatomical study comparing healed and unhealed lesions

Clinical anatomy (New York, N.Y. Print), 2023
The anatomy and pathogenesis of spondylolysis has been widely studied; however, the microanatomy of spondylolysis of the lumbar vertebra has not been well described. Therefore, we aim to better elucidate this anatomy.
