Active clinical trials for "Hallux Rigidus"

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.

The hallux rigidus is the most frequent type of arthrosis at the age of 50 and beyond. For the moderate forms of the disease, the majority of the studies recommend the recourse to the viscosupplement because of its efficiency in the long term. On the other hand, no study was focused on the impact of the anatomical severity on the clinical result of the treatment by intra-articular injection of hyaluronic acid. The present research has for objective to study the influence of the radiological severity on the result of the viscosupplement, in the conditions of daily practice, in patients affected by Hallux rigidus. It is an open observational multicentrical prospective study realized by 20 investigators rheumatologists and liberal orthopedic surgeons. The recruitment is competitive and the study will be ended when 66 patients will have been included by taking into account a risk of trial exits or of lost of sight of 10 %.The main criterion is the influence of the radiological stage on the answer to the treatment. Duration of inclusion 6 months. Duration of follow-up 3 months. Total duration of the study 9 months.

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.

Foot silicone implants suffer from bad reputation on the market, due to poor results obtained with the first generations of implants. Allergies to silicone, infections due to silicone and implants breakage used to be common with previous generations of silicone implants. Publications relative to those implants showed that the survival rates after 5 years of follow-up were unsatisfactory. Since 1998, Tornier has been selling a new generation of silicone implants made of Ultrasil™. The use of this new material in its manufacturing process together with its innovative geometry, make the Primus™ FGT a much more resistant, anatomic and long lasting implant. The main objective of this study is to evaluate the clinical outcomes of the implantation of Primus™ FGT implant in great toe arthroplasty. The study will capture long term outcomes in terms of functional metrics from documented clinical data. Other objectives are to evaluate the outcomes in terms of radiological evaluation and of safety during all the follow-up.

Comparison between 3 groups: group I has hallux rigidus. Is fasicitis plantaris present? group II has fasicitis plantaris. Does the hallux have limited mobility? group III does not have hallux rigidus or fasicitis plantaris

randomized-controlled trial looking specifically at the effect of weight bearing on the outcomes of first MTP joint fusions

Foot disorders have been recognized as being linked to chronic low back pain

The aim was to investigate with a multi-segmental foot model the kinetic and kinematic in patients with a hallux rigidus, before and after different type of surgery.

This study will have implications for any healthcare professionals who routinely manage ingrown toenails. Although different conservative and surgical treatment have been suggested, the recurrent rate is still high ranging from 20% to 30%. The objective of this study was to investigate the association of ingrown toenail (IGTN) with flat foot, hallux abducto valgus (HAV) and hallux limitus (HL), and to provide directions for addressing biomechanical risk factors in the prevention of recurrent ingrown toenails. This was the first study to investigate the association of IGTN with flat foot, and the first study in Chinese community to investigate the association of IGTN with HAV or HL. Participants with ingrown toenails (IGTN) were recruited to this study and compared with control participants with no history of ingrown toenails. The inclusion criteria for the IGTN group were: (1) history of ingrown toenails on hallux within 1 year and (2) dorso-plantar standing view of foot x-ray taken or to be taken. The exclusion criteria for the IGTN group were: (1) paediatrics (Age<18), (2) pincer nails / fungal nails, (3) prior existence of osteoarticular surgery in the foot, (4) severe trauma that changes foot morphology, (5) uncontrolled systemic disease, (6) pre-existing neurological diseases and (7) lower limb paralysis or paresis. The inclusion criterion for the control group was dorso-plantar standing view of foot x-ray taken or to be taken. The exclusion criteria for the control group were: (1) all the exclusion criteria of IGTN group, (2) history of IGTN in his or her lifetime and (3) flatfoot / first metatarsophalangeal joint pathology as the chief complaint. The symptomatic foot (or the more symptomatic foot in the case of bilateral involvement) in the IGTN group was examined. The left or right foot of the control group was randomly selected such that the ratio of the left or the right foot in the IGTN and control group was the same. Their foot posture index-6 components, Staheli's index, radiological hallux valgus angle and active maximum dorsiflexion of the first metatarsophalangeal joint on weight-bearing were measured and compared. For dependent variables with significant correlation, a one-way multivariate analysis of variance (MANOVA) was carried out to determine if there was a significant difference on the combined dependent variables. For dependent variables without significant correlation, separate independent sample t-tests / welch t-tests were performed.

The purpose of this study is to examine variabel pressure gradients of the 1st toe, 2-5th toes and the metatarsal distal caput in patients who have had surgery with a partial proximal hemiarthroplasty in the 1st metatarsalphalangeal joint (MTP) between 2006-2014. Also, to examine these variables and compare them to the totalt range of motion and pain, to find out if the measured pedobar pressure can be used identify the well treated patient and the poorly treated patient. The pedobar pressure gradients will be compared with a control group with healthy feet.
