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

Orthopaedic Surgery
Objective Spondylolysis, often progressing to spondylolisthesis, commonly defies conservative treatment in refractory cases, indicating a need for surgery.

Biomechanical Effects of a Novel Pedicle Screw W-Type Rod Fixation for Lumbar Spondylolysis: A Finite Element Analysis [PDF]

Bioengineering, 2023
Lumbar spondylolysis involves anatomical defects of the pars interarticularis, which causes instability during motion. The instability can be addressed through instrumentation with posterolateral fusion (PLF).

Factors associated with non-fusion after direct pars repair of lumbar spondylolysis with pedicle screw and lamina hook: a clinical and CT-assessed study [PDF]

BMC Musculoskeletal Disorders
Background Pedicle screw and lamina hook (PSLH) technique is an effective and popular method for direct pars repair of lumbar spondylolysis. There is a lack of studies to explore factors that may influence the healing of spondylolysis after direct pars ...

Characteristics of lumbar spondylolysis: L5 versus non-L5 [PDF]

BMC Musculoskeletal Disorders
Background Fifth lumbar vertebra (L5) spondylolysis has a lower bone union rate than non-L5 spondylolysis, but the reason for this is unknown. This study aimed to evaluate the differences in patient and lesion characteristics between L5 and non-L5 ...

Bilateral Spondylolysis of Lumbar Vertebra Secondary to Long Spinal Fusion for Idiopathic Scoliosis: A Case Report and Review of Literature

Orthopaedic Surgery
Background Lumbar spondylolysis is a common cause of low back pain in adolescents. A lot of adolescent idiopathic scoliosis with concomitant spondylolysis has been reported before, but only two cases with acquired spondylolysis following long fusion for ...

Treatment of lumbar spondylolysis in young adults using modified intravertebral screw-rod fixation system for single vertebral body combined with autologous cancellous bone graft: a technical note and preliminary report [PDF]

Journal of Orthopaedic Surgery and Research
Background There is currently no consensus on the surgical treatment of lumbar spondylolysis in young adults, and the nonunion rate remains relatively high even after surgery.

Biomechanical Analysis and Injury Prediction in Pilots With Lumbar Spondylolysis Under Different Seat Inclination Angles. [PDF]

JOR Spine
The biomechanical responses of three lumbar models under both seat angles remain below injury thresholds. However, the occurrence of spondylolysis at a 22° angle poses a higher risk. ABSTRACT Background This study aims to quantify the biomechanical effects of different seat inclinations on the normal and spondylolysis lumbar of pilots under typical ...
