Active clinical trials for "Hallux Valgus"

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)

We hypothesize that the Akin screw fixation osteotomy technique provides better postoperative mobility of the metatarsophalangeal hallux joint compared to the non-fixation technique.

The investigators sought to determine whether bioabsorbable cannulated screws could perform as well as titanium cannulated screws in the Lapidus procedure and MTP1-joint arthorodesis in anatomical models and clinical series of the foot.

This study is developed to determine if the local anaesthetic dose can be reduced by the use of intermittent bolus technique compared to continuous infusion when the nerve catheter is placed underneath the paraneurium by ultrasound guidance in the popliteal fossa. Our primary outcome is local anesthetic use the first 48 hours after connecting the peripheral nerve catheter. Our hypothesis is that with an intermittent bolus less local anaesthetic is necessary the first postoperative 48 hours after surgery for adequate postoperative analgesia. As secondary outcomes the investigators study pain scores, motor block, sensory block, feeling of numbness, patient satisfaction, sleep quality and rescue analgesia during the nerve block and afterwards.

Hallux valgus surgery is known as a painful surgery. Qualitative pain management is the key to successful early recovery and rehabilitation. Popliteal sciatic nerve block is widely used despite the risk of falling due to prolonged motor blockade. Plantar block combined with distal peroneal block may be a better analgesic option in order to provide fast track rehabilitation. The purpose of this study is to describe the analgesic effect of the plantar compartment block following hallux valgus surgery.

The great toe is vital for normal, pain free ambulation. Decreased function associated with osteoarthritis of the first matatarsal phalangeal joint (MTP I) often called Hallux Rigidis or Hallux Limitus leading to a painful great toe. Patients experience pain during ambulation especially during the push-off phase of gait. When surgery is indicated four techniques are used for hallux rigidis; cheilectomie, resection arthroplasty, arthrodesis and implant surgery (1). Endoprostetic implants are relatively new. Silicone Implants like the arthroplasty developed by Swanson (2) resulted in foreign body reactions and periarticular bone loss. Subsequent implants, in particular the metallic hemi arthroplasty with or without polyethylene articulations, have been more successful (3). Still, implants are prone to wear of the material and show higher rates of loosening and infection compared to other techniques (4;5). In the last decades several new implants are described using two non cemented pressfit components, of titanium alloy or ceramic (6-9). Between 2001 and 2004 the investigators developed a new concept with instrumentation for exact alignment to prevent for wear with loosening of the implant on the long term. The implant has bone-conserving characteristics to enable arthrodesis as a salvage procedure. It is a completely modular two-component press fit titanium alloy implant with polyethylene insert that can be used as either for hemi-, total- or revision arthroplasty. The purpose of this study is to have an overview of clinical status of the patient implanted with the METIS® prosthesis at short term (2 years of follow-up). The objective of this study is to evaluate the safety and efficacy of the Metatarso-Phalangeal prosthesis METIS® at short term follow up.

The purpose of this study was to investigate the preemptive effect of ultrasound guided popliteal scistic nerve block on postoperative acute pain in patients with bilateral hallux valgus. After induction of general anesthesia, the leg to be operated first is decided randomly. After the operation of one leg is completed, PSNB is performed on both legs with 0.2% Ropivacaine and surgery is started on the remaining legs. When the surgery is over, check to see which foot pain begins first, how strong the pain is, and whether there are any side effects.

The goal of the study is to gather sufficient patient data to assess real world postoperative function after a first metatarsophalangeal (MTP) joint arthrodesis done in conjunction with first tarsometatarsal arthrodesis (TMT) (double fusion). Many studies have demonstrated the success of a first MTP joint arthrodesis in eliminating pain and reducing the intermetatarsal angle. Very little research has been published to assess the outcomes of double arthrodesis. Limited research has specifically assessed patients' everyday function and gait following MTP arthrodesis and no studies are available to assess real world function following double arthrodesis. More data that includes patient reported function during activities of daily living is needed to understand the benefits and draw backs of combined first MTP/TMT joint arthrodesis used to treat and correct first ray deformity.

This study was designed to demonstrate the prevalence of onychomycosis in hallux valgus patients. Additionally, all the prevalence of tinea pedis, the pattern of clinical manifestations, risk factors and coexistence foot deformities with hallux valgus were observed and recorded.

To investigate relationship between HV deformity and position of rearfoot joints, and its effects on the quality of life, pain, and related functional status in women with bilateral hallux valgus (HV).
