Ultrasound-Guided Proximal Superior Cluneal Nerve Block for Superior Cluneal Nerve Entrapment (PRO-SCN)
Clinical Outcomes of Ultrasound-Guided Proximal Superior Cluneal Nerve Block in Patients With Superior Cluneal Nerve Entrapment
Superior cluneal nerve entrapment (SCNE) is an underrecognized cause of chronic low back pain and gluteal pain that may mimic lumbar spine disorders. Ultrasound-guided proximal superior cluneal nerve block has increasingly been used in routine clinical practice .Diagnostic superior cluneal nerve block is commonly used to confirm the diagnosis, whereas ultrasound-guided proximal superior cluneal nerve block has emerged as a therapeutic option.
This prospective observational cohort study aims to evaluate the clinical outcomes of ultrasound-guided proximal superior cluneal nerve block in patients with clinically diagnosed superior cluneal nerve entrapment who undergo the procedure as part of routine clinical care. Pain intensity, disability, and neuropathic pain characteristics will be assessed at baseline and during follow-up to evaluate treatment outcomes.

Detaillierte Beschreibung
Superior cluneal nerve entrapment (SCNE) is an increasingly recognized cause of chronic low back pain that may be overlooked or misdiagnosed as lumbar radiculopathy or other degenerative lumbar disorders. Accurate diagnosis is essential because patients with SCNE may benefit from targeted peripheral nerve interventions rather than treatments directed at the lumbar spine.
Ultrasound-guided proximal superior cluneal nerve block has emerged as a practical technique for both diagnostic confirmation and therapeutic management of SCNE. Compared with landmark-based approaches, ultrasound guidance enables real-time visualization of relevant anatomical structures and standardized needle placement. Despite increasing clinical use, prospective evidence evaluating the clinical outcomes of this technique remains limited.
This prospective observational cohort study will enroll patients with clinically diagnosed superior cluneal nerve entrapment who undergo ultrasound-guided proximal superior cluneal nerve block as part of routine clinical care. Pain intensity, disability, and neuropathic pain characteristics will be evaluated at baseline and at 1- and 3-month follow-up visits using validated clinical outcome measures.
The primary objective is to evaluate changes in pain intensity following ultrasound-guided proximal superior cluneal nerve block. Secondary objectives include evaluating changes in disability and neuropathic pain characteristics after treatment and documenting the clinical outcomes of this intervention during routine practice.

Patients With Superior Cluneal Nerve Entrapment Undergoing Ultrasound-Guided Proximal Superior Clune
Adults with clinically diagnosed superior cluneal nerve entrapment undergoing ultrasound-guided proximal superior cluneal nerve block as part of routine clinical care.
Participants will undergo baseline clinical assessment followed by follow-up evaluations at 1 and 3 months.
|
Ultrasound-guided proximal superior cluneal nerve block will be performed as part of routine clinical care in patients with clinically diagnosed superior cluneal nerve entrapment.
The proximal superior cluneal nerve will be targeted using a standardized ultrasound-guided interfascial technique.
A standardized injectate will be administered according to the study protocol.
All procedures will be performed by an experienced pain physician using the same technique for all participants.
