Terminal branches of the superficial fibular nerve are at risk of iatrogenic damage during foot surgery, including hallux valgus rigidus correction, bunionectomy, cheilectomy, and extensor hallucis longus tendon transfer. One terminal branch, the dorsomedial cutaneous nerve of the hallux, is particularly at risk of injury at its intersection with the extensor hallucis longus tendon. Iatrogenic injuries of the dorsomedial cutaneous nerve of the hallux can result in sensory loss, neuroma formation, and/or debilitating causalgia...

INTRODUCTION: Hypervascularization of nerves has been shown to be a pathological sign in some peripheral nerve disorders, but has not been investigated in nerve trauma. METHODS: An observational cohort study was performed of the intraneural blood flow of 30 patients (34 nerves) with penetrating nerve injuries, before or after nerve reconstruction. All patients underwent electrophysiological assessment, and B-mode and color Doppler ultrasonography. RESULTS: Intraneural hypervascularization proximal to the site of injury was found in all nerves, which was typically marked and had a longitudinal extension of several centimeters...

BACKGROUND: Open reduction and internal fixation of Lisfranc injuries has typically used multiple longitudinal incisions or a single transverse incision to approach the tarso-metatarsal joint (TMTJ). The incidence of wound-related complications is considerable. We describe a novel single-incision approach that utilizes subcutaneous windows to the medial TMTJ. METHODS: A retrospective review identified 150 patients who underwent open reduction and internal fixation for Lisfranc injuries, via the modified dorsal approach, at our center between January 2011 and June 2016...

We report the first case of distal posterior tibial nerve injury after arthroscopic calcaneoplasty. A 59-year-old male had undergone right arthroscopic calcaneoplasty to treat retrocalcaneal bursitis secondary to a Haglund's deformity. The patient complained of numbness in his right foot immediately after the procedure. Two years later and after numerous assessments and investigations, a lateral plantar nerve and medial calcaneal nerve lesion was diagnosed. In the operating room, the presence of an iatrogenic lesion to the distal right lateral plantar nerve (neuroma incontinuity involving 20% of the nerve) and the medial calcaneal nerve (complete avulsion) was confirmed...

A painful neuroma is a common complication of a peripheral nerve injury or amputation, and it can cause tremendous pain that is resistant to most analgesics. Furthermore, painful neuromas have a high postoperative recurrence rate. Painful neuromas are often accompanied by functional disorders, drastically reducing the patient's quality of life. Several pathophysiological mechanisms have been proposed to explain this type of neuropathic pain, including peripheral and central sensitisation and the involvement of nerve growth factor, α-smooth muscle actin, the cannabinoid CB2 receptor and structural changes in neuroma fibres...

Traumatic proximal sciatic nerve rupture poses surgical repair dilemmas. Disruption often causes a large nerve gap after proximal neuroma and distal scar removal. Also, autologous graft material to bridge the segmental defect may be insufficient, given the sciatic nerve diameter. The authors utilized knee flexion to allow single neurorrhaphy repair of a large sciatic nerve defect, bringing healthy proximal stump to healthy distal segment. To avoid aberrant regeneration, the authors split the sciatic nerve into common peroneal and tibial divisions...

The purpose of this study was to methodically illustrate and highlight the crucial steps of stromal vascular fraction (SVF)-enriched fat grafting as a novel treatment of symptomatic end-neuromata of peripheral sensory nerves, and in this study, specifically of the superficial branch of the radial nerve (SBRN). Despite a multitude of existing treatments, persistent postoperative pain and common pain relapse are still very common, independent of the procedure assessed. The neuroma is microsurgically excised accordingly to standardized protocol...

BACKGROUND: Amputation neuromas (ANs) are reactive hyperplasia of nerve tissues that occur after a trauma or surgery involving the peripheral nerves. Only two previous reports of ANs occurring around the stomach and post gastrectomy have been reported. We report the case of a patient with AN near the remnant stomach who underwent distal gastrectomy for gastric cancer. CASE PRESENTATION: A 76-year-old man underwent distal gastrectomy, D1+ lymphadenectomy, and Billroth-I reconstruction for early gastric cancer in another hospital at 63 years of age...

BACKGROUND: Recently, the transcanal approach for the removal of acoustic neuromas has been introduced. Facial nerve (FN) preservation is one of the main challenges of this kind of surgery. OBJECTIVE: To describe our experience in the surgical treatment of acoustic neuromas, focusing on the functional results of FN preservation after a transcanal approach. METHODS: A retrospective chart review was carried out on clinical data and videos from operations on 49 patients who underwent surgery with a totally transcanal exclusive endoscopic approach for Koos stage I-II lesions, or an enlarged transcanal transpromontorial approach for Koos stage II-III tumors, between March 2012 and February 2017...

The directional trajectory of growing peripheral nerve axons in the adult impacts their successful regeneration to denervated target tissues. Misdirected axons in neuromas, injured nerve trunks, or nerves with attempted repair diminish the success of regeneration. The behavior of adult rodent peripheral sensory neurons in vitro, in turn, is helpful in predicting axonal behavior in vivo. Here, we describe the adaptation of embryonic neuron growth cone turning assays, an important technique in developmental neurobiology, to adult rat sensory neurons...

The acute vestibular syndrome is common and usually has a benign cause. Sometimes, however, even experienced neurologists can find it difficult to determine the cause clinically. Furthermore, neuroimaging is known to be insensitive.We describe two cases of acute vestibular syndrome where conflicting clinical findings contributed to a delay in making the correct diagnosis. The first patient with symptomatic vertigo had signs consistent with horizontal benign paroxysmal positional vertigo but also had an abnormal horizontal head impulse test, superficially suggesting acute vestibular neuritis but later accounted for by the finding of a vestibular schwannoma (acoustic neuroma)...

The rarity of oral soft tissue spindle cell tumors combined with overlapping microscopic patterns can make challenges in their diagnosis and treatment. Oral cavity palisaded encapsulated neuroma is an uncommon lesion which occurs often on the hard palate. It is essential for oral pathologists to be familiar with its histopathology of this lesion is essential since many lesions are probably diagnosed microscopically as neurofibroma or schwannoma. Here, we report a case of oral palisaded encapsulated (solitary circumscribed) neuroma in an unusual site...

Background: Morton's neuroma is a common cause of metatarsalgia and many treatments had been described in literature. However, there have been only a few reports that treat the neuroma with an osteotomy on the proximal, not distal portion of the metatarsal bone using a plate. This study describes the clinical outcome of sliding osteotomy on the proximal metatarsal bone for the treatment of Morton's neuroma. Materials and Methods: Sixty five consecutive patients (85 feet) who underwent surgery for Morton's neuroma between November 2010 and February 2013 were identified from hospital records to include in this retrospective study...
