Middle cluneal nerve entrapment sites in the surgical field.

Introduction: Middle cluneal nerve (MCN) entrapment around the sacroiliac joint elicits low back pain (LBP). For surgical decompression to be successful, the course of the MCN must be known. We retrospectively studied the MCN course in 15 patients who had undergone MCN neurolysis.

Long-term outcome after surgery for middle cluneal nerve entrapment neuropathy.

Purpose: Entrapment of the middle cluneal nerve (MCN-E) can elicit low back pain (LBP). Patients whose LBP responds only transiently to the analgesic effects of MCN blockage may be candidates for surgery. This study addresses its long-term efficacy.

Patient Satisfaction with Surgery for Tarsal- and Carpal- Tunnel Syndrome - Comparative Study.

We compared the treatment satisfaction of patients who had undergone surgery for tarsal tunnel syndrome (TTS) and carpal tunnel syndrome (CTS). We enrolled 44 patients in this study; 23 were operated for CTS and 21 for TTS. All patients had received surgery under a microscope and under local anesthesia.

Magnetic Resonance Imaging Findings in Patients with Tarsal Tunnel Syndrome.

Tarsal tunnel syndrome (TTS) is a common entrapment syndrome whose diagnosis can be difficult. We compared preoperative magnetic resonance imaging (MRI) and operative findings in 23 consecutive TTS patients (28 sides) whose mean age was 74.5 years.

Patient satisfaction with cluneal nerve entrapment surgery.

Introduction: Low back pain (LBP) from superior or middle cluneal nerve entrapment has been addressed surgically. We recorded patient satisfaction with this treatment.

Methods: We included 22 consecutive patients who had undergone surgery for unilateral cluneal nerve entrapment (superior: n = 17, middle: n = 5).

Current Trends in the Surgical Management of Intramedullary Tumors: A Multicenter Study of 1,033 Patients by the Neurospinal Society of Japan.

Objective: We performed a retrospective observational study to demonstrate the surgical risks and long-term prognoses of intramedullary tumors in Japan using a multicenter registry authorized by the Neurospinal Society of Japan.

Methods: Data from 1,033 consecutive patients with intramedullary tumors, treated between 2009 and 2020, were collected from 58 centers. Patients with spinal lipomas or myxopapillary ependymomas were excluded.

Perioperative Complications and Adverse Events after Surgery for Peripheral Nerve- and Para-lumbar Spine Diseases.

Peripheral nerve diseases are common. Para-lumbar spine diseases (PLSDs) include peripheral neuropathy around the lumbar spine, e.g.

Less Invasive Combined Micro- and Endoscopic Neurolysis of Superficial Peroneal Nerve Entrapment: Technical Note.

As superficial peroneal nerve (S-PN) entrapment neuropathy is relatively rare, it may be an elusive clinical entity. For decompression surgery addressing idiopathic S-PN entrapment, narrow-area decompression may be insufficient and long-area decompression along the S-PN from the peroneus longus muscle (PLM) to the peroneal nerve exit site may be required. To render it is less invasive, we performed S-PN neurolysis in a combined microscope/endoscope procedure.

Therapeutic Effect of Mirogabalin on Peripheral Neuropathic Pain due to Lumbar Spine Disease.

Study Design: Retrospective study.

Purpose: This study aims to evaluate the effectiveness of mirogabalin in treatment of peripheral neuropathic pain due to lumbar spine disease.

Overview Of Literature: Mirogabalin is a novel selective ligand for the α2δ subunit of voltage-gated Ca channels.

Treatment of Coexisting Paralumbar Spine Diseases in Patients with Lumbar Disc Herniation.

Lumbar disc herniation (LDH) elicits low back pain (LBP) and lower-limb symptoms. Paralumbar spine disease (PLSD), for example, superior cluneal nerve/middle cluneal nerve entrapment (SCN-EN, MCN-EN) and sacroiliac joint pain (SIJ), may be attributable to LDH whose treatment may not ameliorate their symptoms. We treated LDH patients and addressed their coexisting PLSDs.

Is the Vertebral Posterior Line a Safety Landmark for Cervical Posterior Screw Insertion? - Radiological Study of the Vertebral Artery in the Cervical Spine.

At posterior cervical fixation, iatrogenic injury of the vertebral artery (VA) must be avoided. As the VA is usually located in front of the posterior line of the vertebral body, intraoperative lateral fluoroscopy is used to identify the line. We investigated in how many of 105 patients (210 VAs) this line is a safe marker.

Complication rate, cure rate, and long-term outcomes of microsurgery for intracranial dural arteriovenous fistulae: a multicenter series and systematic review.

Although microsurgery is an established treatment modality for intracranial dural arteriovenous fistula (dAVF), data regarding the perioperative complication rate, cure rate, and long-term outcomes remain scarce. The aims of this study were to describe our original experience with microsurgery, including the surgical complications and pitfalls, and conduct a systematic review of the relevant literature. A multicenter cohort of patients with dAVF treated by microsurgery was retrospectively assessed.

A Case of Juvenile Stroke due to Carotid Artery Dissection from an Elongated Styloid Process-Revisiting Conservative Management.

Carotid artery dissection is a significant etiology of juvenile stroke. Blunt trauma from an elongated styloid process can rarely cause carotid artery dissection, which is one of well-known clinical presentations of Eagle's syndrome as known as stylocarotid syndrome. Growing number of publications contributed improved awareness and diagnostic modalities for this clinical entity, thus the carotid artery dissection from an elongated styloid process is often diagnosed appropriately.

Deep Decompression of the Lateral Femoral Cutaneous Nerve Under Local Anesthesia.

Objective: Meralgia paresthetica is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) caused by compression around the inguinal ligament. We report a surgical alternative for the treatment of meralgia paresthetica under local anesthesia and its outcomes.

Methods: We operated on 12 patients with unilateral meralgia paresthetica whose age at surgery ranged from 62 to 75 years.

Surgical treatment of middle cluneal nerve entrapment neuropathy: technical note.

OBJECTIVE The etiology of low-back pain (LBP) is heterogeneous and is unknown in some patients with chronic pain. Superior cluneal nerve entrapment has been proposed as a causative factor, and some patients suffer severe symptoms. The middle cluneal nerve (MCN) is also implicated in the elicitation of LBP, and its clinical course and etiology remain unclear.

Low back pain due to superior cluneal nerve entrapment: A clinicopathologic study.

Introduction: We studied the clinical and nerve pathologic features in 6 patients whose low back pain (LBP) was relieved by superior cluneal nerve (SCN) neurectomy to determine whether nerve compression was the mechanism underlying this type of LBP.

Methods: All 6 patients (7 nerves) underwent SCN neurectomy for intractable LBP. Their clinical outcomes and the pathologic features of 7 nerves were reviewed.

Low back pain due to middle cluneal nerve entrapment neuropathy.

Purpose: The etiology of low back pain (LBP) is complicated and the diagnosis can be difficult. Superior cluneal nerve entrapment neuropathy (SCN-EN) is a known cause of LBP, although the middle cluneal nerve (MCN) can be implicated in the elicitation of LBP.

Methods: A 76-year-old woman with a 4-year history of severe LBP was admitted to our department in a wheelchair.

Noninfectious prevertebral soft-tissue inflammation and hematoma eliciting swelling after anterior cervical discectomy and fusion.

OBJECTIVE Anterior cervical discectomy and fusion (ACDF) procedures are performed to treat patients with cervical myelopathy or radiculopathy. Dysphagia is a post-ACDF complication. When it coincides with prevertebral space enlargement and inflammation, surgical site infection and pharyngoesophageal perforation must be considered.

Superior Cluneal Nerve Entrapment Neuropathy and Gluteus Medius Muscle Pain: Their Effect on Very Old Patients with Low Back Pain.

Objective: In the very elderly, their general condition and poor compliance with drug regimens can render the treatment of low back pain (LBP) difficult. We report the effectiveness of a less-invasive treatment for intractable LBP from superior cluneal nerve entrapment neuropathy (SCN-EN) and gluteus medius muscle (GMeM) pain.

Patients And Methods: Between April 2013 and March 2015, we treated 17 consecutive elders with LBP, buttock pain, and leg pain.

Long-term Outcome of Surgical Treatment for Superior Cluneal Nerve Entrapment Neuropathy.

Study Design: Prospective observational cohort study.

Objective: The objective of this study was to present the long-term surgical outcomes of operative treatment for superior cluneal nerve (SCN) entrapment neuropathy (SCNEN) and to analyze the causes of poor results and further treatment required.

Summary Of Background Data: There are a few reports of the outcomes of surgical treatment for SCNEN, and most studies describe results for operations conducted under general anesthesia with short follow-up periods.

Repetitive Plantar Flexion (Provocation) Test for the Diagnosis of Intermittent Claudication due to Peroneal Nerve Entrapment Neuropathy: Case Report.

The diagnosis of peroneal nerve (PN) entrapment neuropathy (PNEN) is based on clinical symptoms and nerve conduction studies. However, these studies do not always detect PNEN. Our 64-year-old patient suffered persistent left L5 numbness after two lumbar surgeries.

[Clinical feathers and treatment of peroneal nerve entrapment neuropathy].

Objective: Peroneal nerve entrapment neuropathy (PEN) is generally known as a drop foot with sensory disturbance. However, some patients experience numbness and pain in the affected area without severe paresis due to PEN. We report the clinical features and our surgical results of PEN cases.
