Tail docking of pigs is commonly performed to reduce the incidence of unwanted tail-biting behaviour. Two docking methods are commonly used: blunt trauma cutting (i.e. using side clippers), or cutting and concurrent cauterisation using a hot cautery iron. A potential consequence of tail amputation is the development of neuromas at the docking site. Neuromas have been linked to neuropathic pain, which can influence the longer-term welfare of affected individuals. To determine whether method of tail docking influences the extent of neuroma formation, 75 pigs were allocated to one of three treatments at birth: tail docked using clippers; tail docked using cautery iron; tail left intact...

Multiple endocrine neoplasia type IIb (MEN IIb) is an endocrine disorder which can manifest with tumors such as pheochromocytomas and neuromas. We present the case of a patient with MEN IIb, after bilateral adrenalectomies, on maintenance steroid replacement, who underwent a neuroma resection and developed severe hypotension. There is persistent controversy regarding the general administration of perioperative "stress dose" steroids for patients with adrenal insufficiency. While the most recent literature suggests that stress dose steroids are unnecessary for secondary adrenal insufficiency, the rarer form of primary adrenal insufficiency always requires supplemental steroids, specifically hydrocortisone, when undergoing surgical procedures...

Patients suffering from nerve injury with sensory disturbances or orofacial pain have greatly reduced quality of life, and it is a big cost for the society. Abnormal sensations caused by trigeminal nerve injury often become chronic, severely debilitating, and extremely difficult to treat. In general, non-invasive treatment such as drug treatment has been insufficient, and there are currently few available effective treatments. Surgical interventions such as end-to-end connection or nerve grafting have disadvantages such as donor site morbidity or formation of neuroma...

Traumatic neuroma results from regeneration attempts of the proximal end of an injured or severed nerve, resulting in a non-neoplastic nodular lesion. The lower extremity after amputation is the most common site, followed by the head and neck. Traumatic neuromas occurring in the abdomen, however, are rare. In the abdominal region, traumatic neuromas occur in the cystic duct stump and the common bile ducts as well as around the celiac trunk. This study reports a case of a 59-year-old man who presented with a traumatic neuroma arising at the stump of the inferior mesenteric artery after rectal cancer surgery...

Glomus tumours are rare benign vascular neoplasms commonly found in the hand particularly in subungual region. Though, its aetiology remains largely unknown, several hypotheses have been made to explain the etiopathogenesis and cause of pain. These tumours usually present as a bluish or pinkish red discolouration of the nail plate with classical triad of localised tenderness, severe pain, and cold sensitivity. Nevertheless, differential diagnosis of other painful tumours, such as leiomyoma, eccrine spiradenoma, haemangioma, neuroma, osteochondroma, or mucous cyst should always be kept in mind while evaluating a patient with severe pain in the tip of the finger...

BACKGROUND: The aim of this research was to investigate the association of various structural measurements of the forefoot with Morton's neuroma (MN). METHODS: Weightbearing anteroposterior and lateral foot radiographs of subjects attending the University of Western Australia (UWA) Podiatry Clinic and the first author's private practice were included in this study. A single assessor measured the following angles: lateral intermetatarsal angle (LIMA), intermetatarsal angle (IMA), hallux valgus angle (HVA), digital divergence between the second and third digits (DD23), digital divergence between the third and fourth digits (DD34) and relative metatarsal lengths of the first to fifth metatarsals (Met1-5), and the effect of MN size as measured by ultrasonograph on digital divergence...

A 56-year-old man developed a 2 × 2 mm, yellow-orange painless, smooth-surfaced nodule in the middle third of his left upper eyelid. Microscopic evaluation disclosed a spindle cell tumor that was well circumscribed by a perineurium. The tumor cells manifested wavy, bland nuclei displaying comma-shaped and pointed ends. These cells were uniformly S100 positive. Immunohistochemical analysis further revealed an even dispersion of numerous dot-like neurofilaments diagnostic of an isolated intraneural neuroma...

Neuroma pain can be severe, persistent, and treatment resistant. We present a case of a 37-year-old female amputee who suffered from severe neuroma pain, which had proved resistant to pharmacologic treatment, glycerol injections, spinal cord stimulation, radiofrequency thermocoagulation, and repeated surgical removals. After treatment with peripheral nerve stimulation, using a St. Jude Medical Octrode lead implanted percutaneously under ultrasound guidance close to her painful neuroma, her ongoing pain dramatically decreased from 8 to 3 on a numeric rating scale (0-10)...

Targeted muscle reinnervation (TMR) is a revolutionary surgical technique that, together with advances in upper extremity prostheses and advanced neuromuscular pattern recognition, allows intuitive and coordinated control in multiple planes of motion for shoulder disarticulation and transhumeral amputees. TMR also may provide improvement in neuroma-related pain and may represent an opportunity for sensory reinnervation as advances in prostheses and haptic feedback progress. Although most commonly utilized following shoulder disarticulation and transhumeral amputations, TMR techniques also represent an exciting opportunity for improvement in integrated prosthesis control and neuroma-related pain improvement in patients with transradial amputations...

BACKGROUND: Despite the general success of total knee arthroplasty (TKA), up to 20% of patients report dissatisfaction following surgery. One potential cause of this dissatisfaction is residual pain secondary to neuroma formation in the sensory nerve branches that innervate the knee. We found, after performing a retrospective review, that up to 9.7% of patients following primary TKA and up to 21% of revision cases exhibited persistent knee pain attributable to neuroma formation. Despite the high incidence of this pathology, little is known about the effective diagnosis or treatment of neuroma formation following TKA...

REVIEW
Man-Kyo Chung, James N Campbell
Capsaicin is the pungent ingredient of chili peppers and is approved as a topical treatment of neuropathic pain. The analgesia lasts for several months after a single treatment. Capsaicin selectively activates TRPV1, a Ca(2+)-permeable cationic ion channel that is enriched in the terminals of certain nociceptors. Activation is followed by a prolonged decreased response to noxious stimuli. Interest also exists in the use of injectable capsaicin as a treatment for focal pain conditions, such as arthritis and other musculoskeletal conditions...

Epithelial sheath neuroma is a rarely recognized but established entity in the medical literature. First described in 2000 by Requena et al, there have only been 7 published cases to date, mostly in female patients and presenting as symptomatic solitary lesions on the back without a known history of trauma. In 2006, Beer et al described and reviewed a dozen cases in which epithelial sheath neuroma-like features were seen in the advent of a surgical procedure, which was termed "re-excision perineural invasion" and attributed to possible eccrine duct implantation during surgery...

INTRODUCTION: None of the existing treatments in the management of painful end-neuromas of the superficial branch of the radial nerve (SBRN) has been proven superior due to high levels of pain relapse. Fat grafts enriched with the stromal vascular fraction (SVF) could act as a mechanic barrier with biological effects decreasing the resorption rate and boosting the graft's regenerative potential. This study describes the novel surgical treatment technique of SVF-enriched fat grafting. PATIENTS AND METHODS: In this clinical study, five consecutive patients treated for painful end-neuromas of the SBRN between 2012 and 2013 were analyzed retrospectively...

A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

Background: The repair of a segmental peripheral nerve injury is a clinical challenge. Several studies have been performed to determine superior methods for overcoming nerve gaps. The purpose of this study was to investigate if the inside-out slided epineurium of the distal segment of an injured nerve can serve as a conduit to bridge a short nerve defect (10 mm). Methods: Nineteen sciatic nerves in Sprague-Dawley rats were transected, and a 10-mm gap was left between the ends. A section of distal epineurium was pulled inside out to bridge the gap...
