Hallux Valgus

Hallux valgus is the most common forefoot deformity and primarily affects women. Surgical treatment involves an osteotomy of the first metatarsal to reduce the M1-M2 angle. Often, an osteotomy of the first phalanx of the big toe is performed in conjunction to reduce the M1-P1 angle. Once the deformity has been corrected, the second objective is to restore the foot's function, particularly mobility and plantar flexion strength. To achieve this, rehabilitation is prescribed, but inconsistently due to the lack of clear guidelines and limited patient participation, especially outside of the physiotherapist's scheduled appointments. Continuous passive range of motion exercises can accelerate the return to standard footwear and normal joint mobility. This study is based on the hypothesis that an application connected with rehabilitation exercises to be done outside of sessions with a physiotherapist reproduces this mechanism of continuous passive mobility. In this context, it is hoped that patients benefiting from self-rehabilitation of the foot via the connected application, in addition to traditional care with a physiotherapist, will achieve better postoperative mobility of the metatarsophalangeal joint of the hallux compared to traditional care with a physiotherapist in patients undergoing hallux valgus surgery, with an isolated procedure on the first ray. The main objective is to compare the mobility of the metatarsophalangeal joint of the hallux 6 months after an operation for isolated hallux valgus by osteotomy in patients benefiting from optimized rehabilitation with a physiotherapist using a connected application compared to patients receiving standard care with a physiotherapist.

The purpose of this study is to assess the surgeon experience and surgery outcomes in participants undergoing index Lapidus procedure for the correction of hallux valgus (a foot deformity where the big toe angles outward towards the other toes, causing a painful bony bump at the base of the big toe joint) using the VIRTUGUIDE System and compatible DePuy Synthes Lapidus implants.

Prospective, single-center, randomized interventional clinical trial of tourniquet use in hallux valgus surgery. Patients will be their own controls.

Patients who have undergone arthrodesis of the first metatarsophalangeal joint due to hallux valgus or hallux rigidus are invited to participate in this study, which aims to investigate how the foot functions after this operation. Patients between 18 and 60 years of age at the time of surgery are eligible to participate. Questionnaires will be distributed to assess current sports function compared with function prior to surgery. Particular focus will be placed on function during cross-country skiing.

This is a Phase 2, randomized, double-blind, active-controlled, dose-escalation study evaluating the safety, pharmacokinetics, efficacy, and pharmacodynamics of ALX006, an extended-release bupivacaine formulation, administered as a single-dose sciatic nerve block in the popliteal fossa in adult subjects undergoing primary unilateral bunionectomy. Approximately 60 subjects will be enrolled across 3 sequential dose cohorts (100 mg, 150 mg, 200 mg ALX006), with each cohort comparing ALX006 against MARCAINE 0.25% (bupivacaine HCl 50 mg) as the active comparator at a 3:1 randomization ratio. Dose escalation between cohorts is governed by an Independent Data Monitoring Committee.

This is a pilot study with a randomized controlled design.

The HYALEX SLALOM MTP Hemiarthroplasty System consists of a synthetic implant designed to replace the distal metatarsal surface of the great toe for treatment of arthritis . The system is composed of the HYALEX MTP Implant and instrumentation. The implant consists of the HYALEX Cartilage material bonded to a titanium backing.

The goal of this clinical trial is to compare the treatment of Hallux Valgus using the conventional method (metal screw) with the new method (human allogeneic cortical bone screw (Shark Screw®) in adult patients with confirmed Hallux Valgus. The main questions it aims to answer are: Can the new method obtain comparable results as the conventional method in regard to union rate and time to union? Are the number of complications lower with the new method? Participants will be operated either with the metal screw or with the Shark Screw®. The assignment to the groups is randomized.

Peripheral nerve blocks are essential in ensuring effective regional anesthesia and postoperative analgesia in forefoot surgery for hallux valgus repair, with or without minor concomitant toe procedures. Many factors influence the onset and duration of peripheral nerve blocks. In the advent of ultrasound-guided nerve blocks, the accuracy in administering LA has significantly improved, potentially reducing the required dosage, which is also associated with less risk for toxicity. However, the effect of the concentration of LA on the onset time and duration of ultrasound-guided ankle blocks for forefoot surgery has not yet been studied. This poses a clinically relevant dilemma regarding the necessity of administering lower or higher concentrations of ropivacaine to achieve a clinically relevant faster onset time and longer duration of an ankle block.

The study in question is a post market clinical follow up (PMCF) study to evaluate the safety and performance of bioabsorbable headless compression screw Inion CompressOn in selected fracture, osteotomy and arthrodeses operations of the foot and ankle. The study recruits 125 adult patients who meet the acceptance criteria. The follow-up time for each study patient is 4 years. The study is a single center single group study which is conducted in Tampere University Hospital (TAYS) in Finland. The main focus of the study in terms of performance is to evaluate the bone healing/ossification of operated areas. The main focus of the study in terms of safety is to evaluate the occurrence of adverse events and required revision surgeries that are or might be related to the study device.

The goal of this clinical trial is to comparatively investigate the immediate effects of rigid taping and kinesiological taping applications on foot biomechanics in patients with hallux valgus (HV). The main questions it aims to answer are: Which taping approach (rigid or kinesiology) produces the most effective and fastest treatment response in the management of hallux valgus? Researchers will compare two taping methods to investigate which method offers a more effective and faster treatment response in terms of foot biomechanics. Participants will: 1. Individuals aged 18-65 years 2. Individuals with mild to moderate HV in one or both feet 3. HV patients who do not require/are not suitable for surgery or who refuse surgery and are referred/apply for conservative treatment 4. Individuals who have not engaged in any strenuous exercise or activity (such as running, walking, weight or resistance training, yoga, pilates, aerobics, step, etc.) in the last 2 days before evaluation.

Hallux valgus, commonly known as a bunion, is a condition where the big toe deviates toward the other toes, often causing pain, difficulty with footwear, and decreased quality of life. Surgery can correct the alignment of the big toe, but during recovery the toes must be supported in the correct position so that the improvement is maintained. After this surgery, a spacer is usually placed between the big toe and the second toe for several weeks while the soft tissues heal. Standard spacers made of folded gauze are not custom-shaped to each patient's foot, which may lead to discomfort, skin irritation, or misalignment of the other toes. To address these limitations, a new custom-made spacer has been developed using 3D printing technology. This spacer is individually designed to match each patient's foot shape, with the goal of improving comfort and maintaining proper toe alignment throughout the healing phase. This clinical study will evaluate whether the custom-made 3D-printed spacer is better tolerated by patients than the traditional folded-gauze spacer and whether it helps maintain the corrected position of the big toe after surgery. The study will include 40 adults undergoing bunion surgery. Participants will be randomly assigned, like drawing lots, to receive either the 3D-printed spacer or the standard gauze spacer. Both spacers are applied externally during surgery and are worn continuously for five weeks as part of routine postoperative care. Participants will attend follow-up visits at 1 week, 3 weeks, and 5 weeks after surgery. At each visit, comfort, pain, and any skin irritation caused by the spacer will be evaluated. At the final visit, toe alignment will be assessed using routine weight-bearing X-rays and clinical examination. No additional medical procedures or radiation will be required beyond standard care. The hypothesis of this study is that the custom 3D-printed spacer will be well tolerated and will help maintain better toe alignment compared with the standard folded-gauze spacer. If successful, this personalized approach may improve recovery and patient satisfaction after bunion surgery.

Hallux valgus is a progressive foot deformity characterized by lateral deviation of the great toe and medial displacement of the first metatarsal head. While pain is a common symptom among individuals with HV, alterations in plantar pressure distribution and impaired balance are also frequently observed. These symptoms and biomechanical changes can negatively impact posture and gait mechanics. The aim of this study is to investigate the acute effects of prolonged walking on pain, balance, posture, and gait in individuals with hallux valgus deformity.

This is a two-arm randomized controlled trial with the aim to evaluate the effectiveness and safety of post-operative management after a modified Lapidus arthrodesis with/without an Akin or a Weil/Hohmann surgery fusion with immediate complete weight-bearing compared with partial weight-bearing (10 - 15kg) for 6 weeks as a novel approach for rehabilitation after a foot surgery.

The aim of this study is to examine the immediate effects of mobilization and manipulation versus sham manipulation on plantar pressure, quality of life, and pain in patients with hallux valgus. Participants will be assessed using a sociodemographic data form, the Manchester-Oxford Foot Questionnaire (MOXFQ), the Manchester Scale, goniometric measurements, the Multidimensional Nil Hallux Valgus Scale, the SF-36 Health Survey, the Numeric Pain Rating Scale (NPRS), and plantar pressure analysis via a pedobarographic device. The study will be conducted on a total of 60 feet, with 30 feet assigned to the manipulation group and 30 feet to the sham manipulation group.

Prospective, multicenter, unblinded study to evaluate outcomes of the Adductoplasty™ Procedure in combination with the Lapiplasty® Procedure for patients in need of metatarsus adductus and hallux valgus correction. Up to 80 subjects will be treated in this study at up to 13 clinical sites. Patients 14 years of age or older with symptomatic metatarsus adductus and hallux valgus will be eligible to participate based on the inclusion and exclusion criteria defined in the study protocol.

A total of 150 patients aged 60-80 years with existing foot radiographs will be included in the study. Radiographic evaluations will include measurements of the hallux valgus angle, first intermetatarsal angle, and the metatarsal and phalanx lengths of the first and second toes. The ratio of the second toe phalanx length to the first toe phalanx length will be calculated and recorded. The relationship between the hallux valgus angle, toe lengths, and their ratios will be analyzed using statistical methods.

The aim of this study is to investigate the point or nonsense of treating cartilage lesions at the level of the first metatarsophalane joint. To date, no clear guidelines have been found in the literature with regard to the treatment of cartilage lesions at the MTP I joint during corrective surgery for hallux valgus, nor has it been investigated whether this can have an effect on the clinical outcome.
