Posterior interosseous nerve of the elbow: normal appearances simulating entrapment.
OBJECTIVE In our clinical practice, we have noted a caliber change of the posterior interosseous nerve (PIN) at the elbow as seen in the long axis on sonography simulating nerve entrapment. The objective of this study was to characterize the PIN using sonography in asymptomatic individuals. METHODS Our study retrospectively characterized the PIN in 50 elbows of 47 asymptomatic patients with s...

متن کاملDistance of the Posterior Interosseous Nerve from the Radial Head during Elbow Arthroscopy: An Anatomical Study
Purpose The aims of this study were to measure the distance of the posterior interosseous nerve (PIN) from the radial head (RH) and its variations with forearm movements. Methods Five fresh frozen cadaver specimens were dissected under arthroscopy. An anterior capsulectomy extended to the entire lateral compartment was performed. The need of soft tissue dissection to isolate the nerve in the ...
متن کاملIntraneural neurofibromas involving the posterior interosseous nerve.
Two patients presented with a posterior interosseous nerve palsy with supinator weakness. In each case an intraneural neurofibroma was found proximal to the supinator tunnel with no other stigmata of von Recklinghausen's disease. Both tumours showed a whorl-like histological pattern that has been previously confused with onion-bulb structures in hypertrophic polyneuropathy. Electron-microscopy ...
متن کاملUltrasonographic findings of posterior interosseous nerve syndrome
PURPOSE The purpose of this study was to evaluate the ultrasonographic findings associated with posterior interosseous nerve (PIN) syndrome. METHODS Approval from the Institutional Review Board was obtained. A retrospective review of 908 patients' sonographic images of the upper extremity from January 2001 to October 2010 revealed 10 patients suspicious for a PIN abnormality (7 male and 3 fem...
