The anterior approach to the ankle for surgery can result in injury to the superficial peroneal nerve, resulting in a painful neuroma and significant patient morbidity. A paucity of data is available evaluating the role of the superficial peroneal nerve to deep peroneal nerve transfer as a method of treatment of neuromas in continuity after ankle arthrodesis. We describe 11 patients who underwent nerve transfer with nerve allograft and conduit repair to treat recalcitrant painful neuromas after ankle arthrodesis...

REVIEW
Ahad Sabab, Jaspreet Sandhu, Stephen Bacchi, Alistair Jukes, Andrew Zacest
Vestibular schwannoma (VS) is a brain tumour arising from Schwann cells that is typically closely associated with the vestibulocochlear nerve. Post-operative headaches (POH) are a potentially common complication of surgery for VS. Greatly differing rates of POH have previously been reported, particularly with different surgical approaches. The aim of this review is to identify and summarise the available peer-reviewed evidence on rates of POH following operative (or radiosurgery) treatment for VS, in addition to information about the treatment and prognosis of POH in these patients...

BACKGROUND:  Targeted muscle reinnervation (TMR) is a novel approach to postamputation neuroma pain; however, this has not been explicitly studied. The purpose of this study was to develop a TMR model in hind limb amputated rats. METHODS:  Ten hind limbs from 5 Sprague Dawley cadaver rats were used. Sciatic nerve, main branches of the sciatic nerve (common peroneal, tibial, sural), motor branches from the sciatic nerve to the biceps femoris and cauda femoris, gluteal nerve and its motor branches to the semimembranosus, and biceps femoris and femoral nerve were dissected to look for consistent nerve anatomy that can be used for TMR in the rat hind limb amputation model...

BACKGROUND: Located in the neck beneath the sternocleidomastoid muscle, the cervical plexus comprises a coalition of nerves originating from C1 through C4, which provide input to four cutaneous, seven motor, and three cranial nerves and the sympathetic trunk. Sporadic instances of injury to these superficial nerves have been reported. Nevertheless, this specific anatomical cause of neurogenic pain remains incompletely described and underrecognized. METHODS: Twelve patients presented with pain and were diagnosed with various combinations of injury to the lesser occipital, great auricular, transverse cervical, and supraclavicular nerves...

Voltage-gated sodium channels NaV 1.7, NaV 1.8 and NaV 1.9 have been the focus for pain studies because their mutations are associated with human pain disorders, but the role of NaV 1.6 in pain is less understood. In this study, we selectively knocked out NaV 1.6 in dorsal root ganglion (DRG) neurons, using NaV 1.8-Cre directed or adeno-associated virus (AAV)-Cre mediated approaches, and examined the specific contribution of NaV 1.6 to the tetrodotoxin-sensitive (TTX-S) current in these neurons and its role in neuropathic pain...

The rate of hearing preservation after vestibular schwannoma surgery is variable and is not as high as expected, possibly due to injuries to the posterior semicircular canal while exposing the tumor. The aim of this study was to estimate the risk of posterior semicircular canal injuries using temporal bone computed tomography (CT) scan findings. Temporal bone CT scans of 30 patients selected between 2013 and 2015 were studied. The median age of the patients was 40 years. Two planes were studied: (1) the axial plane that shows the common crus of the posterior semicircular canal and (2) the coronal plane that shows the two crura of the posterior semicircular canal...

BACKGROUND: Lengthening temporalis myoplasty is a faster and less invasive alternative to free muscle transfer for smile reconstruction. However, it requires a nasolabial fold incision, which leaves a midfacial scar. Based on esthetic considerations, a modified approach, involving an extended lazy-S (parotidectomy) incision instead of a nasolabial fold incision, was developed. METHODS: A cadaveric study involving 10 hemifaces was conducted. From February 2013 to March 2016, the modified lengthening temporalis myoplasty procedure was employed in 10 patients...

Morton's neuroma is a compressive neuropathy resulting in perineural fibrosis rather than a neuroma of the plantar digital nerve. Surgical treatment is indicated for patients with a clear diagnosis of Morton's neuroma and no improvement with nonsurgical treatment. The surgical options include isolated intermetatarsal ligament division, isolated interdigital nerve excision, and interdigital nerve excision with intermetatarsal ligament division, with or without submuscular transposition. This can be performed via dorsal or plantar approach...

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...

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...

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 authors report the case of a 52-year-old man who presented with rapid-onset lancinating facial pain consistent with trigeminal neuralgia. Magnetic resonance imaging revealed a nonenhancing small lesion on the right trigeminal nerve concerning for an atypical schwannoma or neuroma. The patient underwent resection of the mass via a right retrosigmoid approach. His facial pain completely resolved immediately postoperatively and had not recurred at 6 months after surgery. The mass was consistent with normal brain tissue (neurons and glial cells) without evidence of mitoses...

This study analyzes the simple ratio of anterior-to-posterior extension of large (>2.5 cm) acoustic neuromas relative to the internal auditory canal (ICA; anterior-posterior [A/P] index) as a tool for predicting risk of facial nerve (FN) injury. In total, 105 patients who underwent microsurgical resection for large acoustic neuromas were analyzed retrospectively. House-Brackmann (HB) scores were assessed immediately postoperatively, at 1 month, and at 1 year. Lateral-medial, inferior-superior, A/P, and maximum diameters were measured from preoperative magnetic resonance images...

Chronic sciatica is a major cause of disability worldwide, but accurate diagnosis of the offending pathology remains challenging. In this report, the feasibility of a fluorodeoxyglucose ((18)F-FDG) positron emission tomography/magnetic resonance imaging (PET/MRI) approach for improved diagnosis of chronic sciatica is presented. Methods:(18)F-FDG PET/MRI was performed on 9 chronic sciatica patients and 5 healthy volunteers. Region-of-interest analysis using maximum standardized uptake values (SUVmax) was performed, and (18)F-FDG uptake in lesions was compared with the corresponding areas in healthy controls...

Over the past 50 years, the focus of acoustic neuroma surgery has shifted from low mortality and tumor resection to retention of neurological function. Hearing preservation is another point in addition to facial nerve function preservation. Hearing preservation rates overall ranged from 2% to 93% in recent studies. Characteristics such as approach, pre-operative neurological function, tumor size, nerve of origin and fundal fluid of the internal auditory canal have been reported as possible influencing factors...

BACKGROUND: In the dorsal incisional approach for Morton's neuroma, it is required to transect the deep transverse metatarsal ligament (DTML) that lies in the interspace between the third and fourth metatarsal heads. The purpose of this study was to evaluate the relationship between transection of the DTML in the third intermetatarsal space and the metatarsal alignment. METHODS: Nine human cadaveric lower extremity limbs were used for this study. Each limb was mounted to the MTS 858 Mini Bionix biomechanical test system and loaded to 120% of the donor's documented body weight at a rate of 15 lbf/s, in order to simulate peak weightbearing ground reactive forces on the forefoot...
