Hallux valgus can be defined as a progressive subluxation of the first metatarsophalangeal joint and lateral deviation of the hallux. This common foot condition is associated with altered gait patterns. Specifically reduced forward propulsion, leading to gait instability. Research has shown that foot problems and pain play a major role towards the contribution of falls in the adult population. There are currently two main interventions for the treatment of hallux valgus: surgery and orthotic prescription. There has not been a lot of research performed evaluating the effects of custom orthotic prescription on hallux valgus. Therefore, this study will investigate adults with moderate hallux valgus and the effects of orthotic intervention on the efficacy of forward propulsion during walking. It is hypothesized that implementation of an orthotic will lead to decreased foot pain, an increase in step length, an increase in the forward moment about the ankle and hallux, and a more medial center of pressure tracking through the great toe instead of the lesser metatarsals. This study will consist of 10 adults. The participant will go through three rounds of testing in the lab. The first session will consist of initial baseline testing in which each participant will be evaluated for severity of Hallux Valgus and range of motion of the first metatarsophalangeal joint. A foot casting will then be performed by a pedorthist and the participant will be set up with markers, so as to record motion while they perform 15 walking trials across a 10m runway with a force plate embedded in the middle whilst wearing standard footwear (no orthotic). The second lab session will consist of the standard footwear (no orthotic) walking as well as the addition of standard footwear with custom orthotic walking. The third session, after having worn the orthotic for two weeks, will repeat both conditions measured in the second lab session. Data about the center of pressure trajectories, step length, foot pain, and the moments about the ankle and first metatarsophalangeal joints will be collected and calculated.
This is a clinical trial that intend to determine if transcranial direct current stimulation (tDCS) is effective in the treatment of postoperative pain and in the anxiety level in the preoperative period of hallux valgus surgical treatment
Patients often seek advice from their treating doctor if they are able to drive with a foot orthosis after a first metatarsal osteotomy for symptomatic hallux valgus and/or after an additional forefoot surgery. This challenging question is of obvious importance for the patient and other road users. Previous studies already issued driving ability after different orthopedic procedures and with knee and ankle devices on the brake reaction time but missed to address the same for foot orthoses after hallux valgus or forefoot surgery. This missing evidence made us evaluate the influence of wearing a foot orthosis after a first metatarsal osteotomy or forefoot surgery on driving ability (brake response time; BRT). The overall time frame is about nine weeks; each appointment for BRT measurement takes about fifteen to twenty minutes. The first BRT measurement is one day before the foot surgery without a foot orthosis (normal shoe)and with the orthoses (control run) (1) at two days (2), two weeks (3), four weeks (4) and six weeks (5) after the operation with a HVS and a FRS and eight weeks postoperative without a foot orthoses (6).
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 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.
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 aim of the study is to evaluate if Magnesium added to ropivacaine can reduce onset time and can enhance offset time.
The aim of this study is to investigate the effect of continuous wound infiltration with ropivacaine in comparison to standard pain management after elective distal metatarsal osteotomy for postoperative pain control.
In practice ambulatory orthopedic surgery, one of the problems of most difficult solution is adequate control of postoperative analgesia. Pain is a frequent cause of consultation and unscheduled readmissions in this group of patients. The use of continuous peripheral nerve blocks are an effective tool in postoperative analgesia. In this connection, most of the studies of continuous infusions of local anesthetics by perineural catheters have been made with bupivacaine, levobupivacaine, and ropivacaine However, it has been found that lidocaine action lasts less, has lower cost and is less toxic than longer-acting agents. The investigators aim is to compare the effectiveness of lidocaine versus bupivacaine continuous popliteal sciatic blockade ambulatory elastomeric pump.
