7 Αυγ 2023 · Spondylolysis is a unilateral or bilateral defect in the region of the pars interarticularis, (isthmus or bone bridge between the inferior and superior articular surfaces of a single vertebra) is most commonly the result of repetitive trauma to the growing immature skeleton of a genetically susceptible individual.
7 Αυγ 2023 · Identify the different types of spondylolisthesis, differentiating the patholological features that distinguish each variety. Outline the components of a proper evaluation and assessment of a patient presenting with lumbar spondylolysis/spondylolisthesis, including any indicated imaging studies.
Radiographic studies and other more detailed imaging modalities assist in the diagnosis of spondylolysis. Several imaging modalities may play a role in the identification of a symptomatic pars lesion. The radiographic visualisation of a pars lesion is essential in establishing the diagnosis of symptomatic spondylolysis 17.
Lumbar pars interarticularis (PI) injury or spondylolysis occurs only in humans. This represents a stress fracture of the PI. Excessive loading in repetitive hyperextension is a significant risk factor and occurs most commonly at L5 followed by L4.
Methods: We conducted a narrative review of the literature on the clinical presentation, diagnosis, prognosis and management of spondylolysis and isthmic spondylolisthesis. Results: A comprehensive physical exam and subsequent imaging including radiographs, CT and MRI play a role in the diagnosis of this disease process.
22 Ιουν 2024 · The chapter delves into a comprehensive examination of both diagnosis and treatment strategies for spondylolysis and spondylolisthesis. Spondylolysis, a condition characterized by defects or fractures in the pars interarticularis, presents a significant concern in...
The biomechanics and pathophysiology of spondylolysis are complex and debated. Imaging is utilized to detect spondylolysis, distinguish acute and active lesions from chronic inactive non-union, help establish prognosis, guide treatment, and to assess bony healing.
