High-resolution ultrasound of the posterior femoral cutaneous nerve: visualization and initial experience with patients

Abstract

We confirmed the reliable visualization of the PFCN using HRUS. This offers a new technique for the assessment of the PFCN, which could also be demonstrated with the case series presented.

A brief report on a technical description of ultrasound-guided lumbar sympathetic block

“…The frequent use of USG for regional anesthesia and pain procedures has familiarized its use among practitioners [1718]. US provides a reliable setup in localizing the anterior fascia of psoas muscle, as well as the relative position of the needle with respect to surrounding tissues.…”

Ultrasound Features of the Proximal Hamstring Muscle‐Tendon‐Bone Unit

“…Lateral to the hamstring muscle complex tendon, the sciatic nerve, a fascicular and flattened structure, can be easily shown: it descends between and deep to the long head of the biceps femoris and the semimembranosus tendon, superficial to the adductor magnus muscle . A smaller nerve departing from the sciatic nerve, the posterior femoral cutaneous nerve, may be sometimes depicted as well in healthy and slender patients, accompanied by the inferior gluteal artery (Figure ); it distally passes superficial to the long head of the biceps femoris and gradually surfaces up to the cutaneous layer …”

“…Hamstring syndrome may be associated with sciatic involvement. Pain with sitting may be also related to posterior femoral cutaneous nerve entrapment because of its closer proximity to the hamstring muscle complex proximal tendons, as this sensory nerve provides the innervation for the inferolateral gluteal region and posterior aspect of the thigh, the superomedial perineal region, and the skin at the popliteal fossa …”

Images from a 10-year-old boy who had sudden posterior pain while playing soccer.…”

Ultrasound‐Guided Posterior Femoral Cutaneous Nerve Block: A Cadaveric Study

“…Topçu and Aysel reported a single case of an ultrasound (US)‐guided PFCN block for a posterior thigh debridement and skin graft operation in 2014. In 2015, Meng et al reported that the PFCN was readily visualized and blocked with US guidance in the distal and mid thigh, but with some difficulty in the proximal thigh. However, a more proximal approach would be desirable for providing complete anesthesia to the posterior thigh.…”
