Active clinical trials for "Hallux Valgus"

The purpose of this double blind, randomized study is to evaluate which rate and duration of infusion can be recommended for continuous perisciatic infusion of ropivacaine 2 mg/ml for analgesia after ambulatory foot surgery.

Single center, open-label, single arm, pilot study designed to evaluate safety, tolerability and efficacy of CYCLAPLEX device, a minimal invasive enhanced suture and button implant and surgery tools for correction of inter-metatarsal angle in subjects suffering from mild to moderate Hallux Valgus deformity

Hallux surgery is known to be extremely painful. Standard pain therapy is treatment with NSAID and opioid painkillers. Patients are frequently not-satisfied with this. Some institutions use a nerve block (single shot or catheter technic) of the ischiadic nerve. But this procedure is invasive, has a potential risk of nerve lesion, and is not accepted by all surgeons. A single shot nerve block of the posterior tibial nerve is less invasive and could be superior compared to standard pain treatment. A great variability of nerve supply of the foot is well described. There are some hints that the posterior tibial nerve supplies the first metatarsal bone and the first metatarsal joint. A nerve block could reduce postoperative pain in hallux surgery. To assess the effectiveness of this investigated measure, the requested morphine dose of a PCA pump will be used to verify the effectiveness of the tibial nerve block.

60 patients ASA I-III, undergoing orthopedic surgery will be randomly assigned into one of three groups, namely group A (n=20), where dexmedetomidine will be used for sedation (initial bolus dose followed by continuous infusion), group B (n=20) where midazolam will be used for sedation (initial bolus dose followed by continuous infusion) and group C (n=20), where remifentanil will be used for sedation (initial bolus dose followed by continuous infusion). All patients will receive spinal anesthesia. Duration of postoperative analgesia, total dose of patient controlled IV morphine, sedation scores, nausea and vomiting, time of ambulation, sleep quality and patient satisfaction will be recorded for the first postoperative day. Additionally chronic pain on the site of surgery will be recorded in 3 and 6 months postoperatively.

Hallux valgus can be associated with hypermobility of 1st ray. Surgical decision for hallux valgus can be affected by hyper mobility of 1st ray so our clinical trial involved patients with bilateral hallux valgus were planned to underwent fusion of 1st ray and soft tissue correction plus bonionectomy for one foot and for other foot surgical treatment involves corrective osteotomy and soft tissue procedure plus bonionectomy without fusion of 1st tarsometatarsal joint.

Comparison between two techniques of osteotomy wich are more or less invasive : two criterias : clinical data and x-rays data. All patients operated for hallux valgus for 01/01/99 to 31/12/03 in the department of bone surgery CHU Limoges : Scarf or Jonhson (chevron) osteotomy Experienced surgeon : Pr ARNAUD, Pr MABIT or Pr CHARISSOUX.

The aim of this study is to assess the feasibility of conducting a study to compare the patient recorded and clinical outcomes for the surgical management of Hallux Valgus correction. A prospective trial will randomise the patients into two groups - Open Scarf/Akin osteotomy and Minimally Invasive Chevron/Akin osteotomy.

This study evaluates the demineralized bone matrix in "Hallux valgus".

The purpose of this study was to compare a minimally invasive scarf technique and the well-established open scarf technique for correction of hallux valgus deformity.

Hallux valgus is the most common deformity of forefoot and the patients would suffer pain and disable of walking and wearing normal shoes. Chevron osteotomy of the first metatarsal is widely used for the treatment of mild or medium hallux valgus. It is a "V" sharp osteotomy that can decrease the intermetatarsal degree of first-second metatarsal by pushing the distal side of osteotomy laterally.A 2.5mm or 3.0mm steel cannulated screw is usually used for the fixation of the osteotomy side to provide stability.However,there are some shortcomings of steel screws such as rejection of internal fixation or the financial cost of the second surgery of fixation taken-out. To obviate these shortcomings of steel screws, bioabsorbable screw fixation may be an alternative method for chevron osteotomy. This trial is a randomized, prospective, controlled, parallel experimental design, to compare the clinical and radiographic outcomes of bioabsorbable screw versus steel screw for the treatment of hallux valgus with chevron osteotomy. The patients will be randomized to two groups, one treated with bioabsorbable screws while the other treated with steel screws.Data collection for the outcomes measures will occur pre-op,immediate post-op and then 6 weeks, 12 weeks, and at 1 years post operation. The clinical outcomes measure are the VAS (visual analogue scale) score and AOFAS (American orthopedic foot and ankle society) forefoot score.The radiographic outcomes measures are the IMA (intermetatarsal angle) and the HVA (hallux valgus angle)
