Is Ultrasonography Comparable to MRI for the Detection of Morton Neuroma of the Foot?
Morton NeuromaPatients with Morton neuroma of the foot will undergo either ultrasonography or MRI. The results will be compared. In case of surgery, the pathology report will be compared with the ultrasonographic or MRI findings. Which is the most reliable and specific: ultrasonography or MRI?
Concentration and Activity of Lapatinib in Vestibular Schwannomas
Vestibular SchwannomaNF23 moreTumors can grow on the auditory nerves and can cause hearing loss. A common type of tumor that does this is a vestibular schwannoma (VS), or acoustic neuroma. These tumors are not cancerous. Most often, people have only one VS. Occasionally, people have more than one VS and may have a condition called neurofibromatosis type 2 (NF2). Because VS can cause hearing loss, many people with VS will have treatment to preserve their hearing. This treatment usually involves surgery or radiation therapy. There are risks to these procedures, and sometimes they do not work to prevent hearing loss. Because surgery and radiation have risks and are not able to help everyone with VS, other methods of treatment are being explored. One area of exploration is looking to see if there is a drug that can be taken that might prevent the VS from growing larger and causing hearing loss, and might possibly even cause the VS to shrink in size. This study is exploring whether a drug that is approved by the FDA and is currently used to treat breast cancer might also work to treat VS. This study will measure the amount of drug that travels from the bloodstream and arrives at the tumor. This drug is safe and has few side effects. If this drug is shown to reach the tumor, it might be used in the future to treat VS without needing surgery or radiation. This study is recruiting people who are having surgery for VS. If you are going to have surgery to treat a VS, you may be eligible to participate.
Feasibility of Specific Anesthesia of the Forefoot Preserving the Sensitivity of the Heel for Foot...
Hallux Valgus and Bunion (Disorder)Morton Neuroma4 moreFoot surgery is a painful surgery that is usually scheduled in outpatients. A good management of analgesia is the crucial point. Regional anesthesia (RA) is the gold standard, that provides good anesthesia and a long duration of analgesia. The sciatic nerve block (or its branches) is the most adapted analgesic technique. Limitation of proximal sciatic block is the motor block of the ankle and results in the impossibility, for the patient, to walk during the early post-operative period. Distal block of the sciatic nerve (tibial and fibular nerve blocks), at the level of the ankle, has been proposed to maintain the mobility of the ankle, to make deambulation with crutches easier. Nevertheless, the lack of sensibility of the heel remains a limitation for early walking, even with adapted shoes (ie : Barouk). A specific anesthesia of the distal part of the foot, respecting the heel, could be the best option to provide an early deambulation and a suitable analgesia. Ultrasound identification and specific anesthesia of the branches supplying the distal part of the foot (medial and lateral plantar nerves) could meet this dual objective : good anesthesia and suitable analgesia for early deambulation. This study is a feasibility study of a specific block of the plantar branches of the tibial nerve, to preserve the sensibility of the heel, in case of foot surgery. The safety of the procedure will be assessed according to the rate of postoperative dysesthesia.
Lidocaine and Neuroma Pain Related Modalities
Neuropathic PainBackground Subanesthetics concentrations of lidocaine are able to produce a differential block of the ectopic discharges, but not propagation of impulses, suppressing differentially the associated neuropathic pain symptoms. The aim of this study was to investigate the differences between the analgesic effects of lidocaine 0.5% and a control group of lidocaine 0.1% on several neuroma related pain modalities. Methods Sixteen patients with neuropathic pain due to painful neuromas caused by nerve injury participated in this randomized, double-blind experiment. The patterns of sensory changes were compared before and after injection of 1 ml lidocaine 0.5% and 0.1% close to the neuroma, the sessions being 1-2 weeks apart. Spontaneous and evoked pains were assessed using a visual analogue scale (VAS), quantitative and qualitative sensory testing.

Comparison of Alcohol and Steroid Injection for Treating Morton's Neuroma
Morton's NeuromaInterdigital neuroma is a painful forefoot disorder characterized by plantar pain and toe paresthesias thought to result from entrapment of the interdigital nerve by the overlying transverse metatarsal ligament. Multiple treatments have been recommended for this condition and range from modification of shoe wear to surgical excision of the painful nerve. Serial ethanol injection therapy has been reported to be an effective alternative to surgical excision. However, despite wide adoption of this treatment, no randomized, double blinded, placebo-controlled study exists to verify the efficacy of this treatment in comparison to longer standing similar therapies, such as corticosteroid injection. 120 patients from one Orthopaedic group's foot and ankle offices with single foot neuromas and no previous history of neuroma or foot disorder treatment will be selected for the study. These patients will be randomized to three treatments, specifically lidocaine injection, corticosteroid injection, or ethanol injection. Outcomes will be assessed at 3, 6 and 12 month time points using validated questionnaires as well as a non-validated disease specific questionnaire. Primary endpoint will be graded change in the physical function portion of the SF-36 form. Secondary endpoints will be the graded change in the McGill Short Form for Pain and ultimate satisfaction with treatment as assessed by a non-validated questionnaire designed for Morton's neuroma symptoms.
Blind and Ultrasound Guided Injection in Morton Neuroma
Morton NeuromaThe aim of this work trial is to compare the effectiveness of blind and ultrasound guided injection for Morton neuroma in order to determine which is more appropriate as the initial procedure in conservative treatment
Morton's Neuroma: Manipulation Versus Steroid Injection
NeuromaHuman ForefootThe aim of this study is to establish which of two treatment options is the preferred intervention in the treatment of Morton's Neuroma. A randomised controlled trial shall be performed. Steroid injection is the current gold standard conservative treatment for this condition. Therefore, manipulation shall be compared to a control group receiving a steroid injection in an equality randomised controlled trial. Outcomes will be compared using visual analogue pain scales (VAS), The Manchester-Oxford Foot Questionnaire (MOXFQ), The Foot and Ankle Ability Measure (FAAM), the SF-36 quality of life questionnaire and algometric pressure threshold testing. An improvement in either groups' VAS of 20mm above the other group shall be considered as the minimum worthwhile change as this has been identified as the minimum clinically important difference in pain between treatment groups in visual analogue pain scales. There is limited research evidence to support the management of Morton's neuroma with steroid injection although its efficacy has only been demonstrated in the short term.
Focused Ultrasound Treatment of Stump Neuromas for the Relief of Chronic Post-Amputation Neuropathic...
Phantom Limb PainResidual Limbs1 moreAIM: To provide initial information on the efficacy (pain reduction) and safety of focused ultrasound surgery for the ablation of stump neuromas in amputees with chronic neuropathic pain. PARTICIPANTS: The study will include 10 amputees (men/women age >18 years old) with chronic (>3 months) phantom/residual limb pain (NPS ≥ 4). DESIGN: Patients potentially qualifying for the study will be offered an Informed Consent to sign prior to further evaluation. Those who accept will sign the informed consent, complete study questionnaires and be evaluated in terms of inclusion/exclusion criteria. Specifically, a complete medical history will be obtained to determine the patient's general health status, current symptoms, frequency and dosage of their current analgesic intake etc. Baseline pain scores will be established. If not performed within six months prior to the evaluation, a contrast MRI of the stump will be performed. Patients not meeting the study criteria will be exited from the study as screen failures and not be included in analyses. All qualifying patients will complete a baseline MRI exam on treatment day. Any patient not meeting study criteria at Imaging will be exited as screen failures. After completion of the MRI exam, qualifying patients will proceed to the ExAblate treatment. These patients will then be followed for 6-months post-ExAblate treatment; the patients will complete study follow-up questionnaires at 1, 3 days, 1 and 2 weeks, and 1, 3 and 6 months after treatments. Follow-up visits will take place 1 week and 1, 3 and 6 months after treatment to assess their pain status, their quality of life and safety. Data regarding dosage and frequency of analgesic intake for the management of post amputation NP will be collected. Relevant cost data will be collected in order to enable an assessment of the total cost of the procedure.
Neuromas as the Cause of Pain
Neuropathic PainNeuromaNeuromas are frequent after trauma and surgery, including amputation and can be identified by high-resolution ultrasound. The role of neuromas as the cause of neuropathic pain is uncertain. The investigators therefore wish to explore if spontaneous and evoked pain will be relieved by injection of local anesthetics near painful neuromas in subjects with peripheral nerve injury.
