Active clinical trials for "Bunion"

The primary objective of this study is to investigate the effectiveness of mold making silicone toe separator on reducing the hallux valgus angle. In addition, this study aims to determine the compliance of mold making silicone toe separator, the change in pain level and, including, the satisfaction of the participants after using mold making silicone toe separator.

The FASTFORWARDTM Bunion Correction system has been cleared by the United States Food and Drug Administration for sale. This study is to investigate the clinical outcome of MedShape FASTFORWARDTM Bunion Correction system in treating hallux valgus patients at CMUH. Criteria-There will be 12 subjects with a painful bunion and hallux valgus between 20 and 65 years of age and an adequate range of movement. Patients with rheumatoid arthritis, failed previous hallux valgus surgery and symptomatic and/or radiological arthritis of the MTP joint will be excluded. Protocol-The PI and SC explain the detail and purpose of the project to the patient to the language to the patient is comfortable with. The explanation has to be at least 1 hour. Be sure the patients understand the full detail before the surgery. Computer tomography scan, gait analysis and blood biochemical analysis will be taken in 1-2 weeks after patient is enrolled in the subject. Before surgery, the titration bone tether plate designed to match patent's second metatarsal contour will be manufactured using 3D printing technology. Printed titanium plate and PEEK screws used to secure tethering suture tape in the first metatarsal will be sterilized prior implantation. The surgery time, recovery period and effectiveness after implantation will be recorded. To observing the recovery situation, patients will back to out-patient clinic at 1st, 2nd, 3rd, 4th, 6th, 12th, 24th weeks. During these period, physical examination, wound dressing, VAS, X-ray scan will be arranged. The detail arrangements below: 1.1st week: physical examination, wound dressing, VAS 2.2nd week: physical examination, wound dressing, VAS 3.3rd week: physical examination, wound dressing, VAS, X-ray scan, remove stiches 4.4th week: physical examination, VAS 5.6th week: physical examination, VAS, X-ray scan 6.12th week: physical examination, VAS, X-ray scan 7.24th week: physical examination, VAS, X-ray scan, CT scan, gait analysis

Exparel is an FDA-approved local anesthetic (bupivacaine), in a long-release formulation. In this study the investigators plan to determine the ability of Exparel to control post-operative pain in common first metatarsophalangeal (MTP) joint procedures (bunion surgery, 1st MTP fusion, and cheilectomy).

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.

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.

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)
