Lateral Elbow Tendinopathy

Background: In a study from our institution, ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon for recalcitrant lateral elbow tendinopathy showed excellent safety profiles, high tolerability, efficiency, sustained pain relief, functional improvement, and sonographic evidence of tissue healing in 20 patients at 3 years’ follow-up. Purpose: To explore the long-term clinical and sonographic results of ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon. Study Design: Case series; Level of evidence, 4. Methods: The same cohort of 20 patients was recalled after 7 years, and visual analog scale (VAS) for pain and Disabilities of the Arm, Shoulder and Hand (DASH) scores, need for secondary intervention, and overall satisfaction were assessed. They were also reassessed using ultrasound imaging of the brevis and the common extensor tendon to evaluate tendon hypervascularity, tendon thickness, and the progress or the recurrence of the hypoechoic scar tissue. Results: We successfully scored 19 patients and performed ultrasound on 16 patients with a median follow-up of 90 months (range, 86-102 months). There were no adverse outcomes and satisfaction remained at 100% (6 patients, satisfied; 13 patients, very satisfied). No patient developed a recurrence of symptoms and signs of lateral elbow tendinopathy, and therefore no secondary intervention was required. The improvement from baseline and early term scores was sustained ( P < .001 for all). At 90 months, there was a significant improvement in VAS scores and DASH–Compulsory scores compared with preprocedure scores and all follow-up times until 3 months. There was no difference in VAS scores and DASH–Compulsory scores at 90 months compared with 6 and 36 months. For DASH–Work scores, there was a significant improvement at 90 months compared with preprocedure scores, but there was no difference between DASH–Work scores at 90 months and scores at all other points of follow-up. At 90 months, hypervascularity remained resolved in 79% of patients, while all patients had reduced tendon swelling and sustained resolution or reduction of the hypoechoic lesion. Conclusion: At the long-term follow-up of 90 months, ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon, previously shown to enhance recovery of lateral elbow tendinopathy, demonstrated good durability of pain relief and functional recovery that was previously achieved. This was accompanied by sustained sonographic tissue healing with no significant deterioration.

Protein misfolding has been an area of intense research and is implicated in a number of neurodegenerative diseases. Key proteins in the brain lose their native ability to fold and instead assume abnormal conformations. Misfolded proteins cluster to form pathologic aggregates, which cause cellular dysfunction, neuronal death, and neurodegeneration. The prionopathies are best known among the neurodegenerative diseases for their ability to misfold, self-propagate, and infect other organisms. There is increasing evidence of a rationale for a prionlike mechanism of spread of other neurodegenerative diseases through a similar seeding mechanism. In this review, we detail the role of a key protein aberration known to the various prion diseases, including sporadic, variant, and iatrogenic Creutzfeldt-Jakob disease; variably protease-sensitive prionopathy; Gerstmann-Straussler-Scheinker disease; fatal familial insomnia; and kuru. We also discuss the clinical presentation, the available, and emerging imaging options for these diseases. In the second part of this review, we delineate how a prionlike seeding process may be driving the progression of other neurodegenerative diseases, including Parkinson disease, Alzheimer disease, and Huntington disease. A discussion of clinical presentation and imaging features of these example diseases follows to make a case for a common approach to developing imaging biomarkers and therapies of these diseases.Learning Objective: Upon completion of this article, one should be able to describe the various types of prion diseases, recognize and identify the common the neuro-imaging findings in prion diseases, describe seeding mechanism of prion disease, list the common amyloid PET tracers used for Alzheimer’s disease, and list common imaging biomarkers in neurodegenerative diseases.
