Spontaneous Reduction in the Intermetatarsal Angle in Distal First Metatarsal Osteotomies with No Lateral Head Displacement in Hallux Valgus.

Background: The outcomes of first metatarsal (M1) distal osteotomies in hallux valgus (HV) can be improved, especially for intermetatarsal angle (IMA) correction, which is mainly based on lateral displacement of the M1 head (i.e., translation) through the osteotomy.

Recurrence Rates With Longer-Term Follow-up After Hallux Valgus Surgical Treatment With Distal Metatarsal Osteotomies: A Systematic Review and Meta-analysis.

Background: Recurrence of hallux valgus (HV) following corrective surgery is a frequent concern. A recent systematic review estimated recurrence of HV in only 4.9%, which may be an underestimation, as most included studies had short- to mid-term follow-up.

Impact of First Metatarsal Hyperpronation on First Ray Alignment: A Study in Cadavers.

Background: There is increased evidence of first metatarsal hyperpronation in patients with hallux valgus, but its impact on the stability of the first metatarsophalangeal and metatarsosesamoid joints is unknown. A previous biomechanical study showed that an increase in hallucal pronation might lead to medial soft tissue failure of the first metatarsophalangeal joint. Conversely, dynamic studies on hallux valgus have shown that the first tarsometatarsal joint moves in supination during weightbearing, and supination was associated with an increase in the intermetatarsal angle (IMA) and hallux valgus angle (HVA).

Open-Label Pilot Study of a Single Intra-Articular Injection of Mannitol-Modified Cross-Linked Hyaluronic Acid (HANOX-M-XL) for the Treatment of the First Metatarsophalangeal Osteoarthritis (Hallux Rigidus): The REPAR Trial.

Purpose: The purpose of this study was to obtain information on safety and short-term efficiency of a single intra-articular injection of mannitol-modified cross-linked hyaluronic acid (HANOX-M-XL) in patients with painful first metatarsophalangeal joint osteoarthritis (1stMTPJ-OA).

Methods: The study involved an observational, single-arm, prospective multicentre trial, with a 3-month follow-up. Inclusion criteria were patients with symptomatic 1st MTPJ-OA not relieved by analgesics and / or non-steroidal-anti-inflammatory drugs and / or foot orthotic.

Tarsal Tunnel Syndrome: Outcome According to Etiology.

Surgical results in tarsal tunnel syndrome are variable, and etiology seems to be a factor. Three possible etiologies can be distinguished. The aim of the present study was to compare surgical results according to etiology.

Predictive factors of effective tibial nerve release in tarsal tunnel syndrome.

Background: Factors that may affect surgical decompression results in tarsal tunnel syndrome are not known.

Methods: A retrospective single-center study included patients who had undergone surgical tibial nerve release. The effectiveness of decompression was evaluated according to whether the patient would or would not be willing to undergo another surgical procedure in similar preoperative circumstances.

Distal Metatarsal Minimally Invasive Osteotomy (DMMO): Surgical technique, variants, indications, and treatment decision-tree.

Background: Metatarsal osteotomy is a major means of treating mechanical metatarsalgia. Open techniques are widely used, and notably that described by Weil. They have, however, certain drawbacks, and new types of osteotomy have been developed.

Incidence and outcomes of revision surgery after first metatarsophalangeal joint arthrodesis: Multicenter study of 158 cases.

Introduction: First metatarsophalangeal (MTP1) joint arthrodesis, described as a safe and effective procedure, has complications that may require surgical revision. These complications are rarely studied. The aim of this study was to determine the incidence and outcomes of revision surgery after MT1 arthrodesis.

Stabilization of proximal interphalangeal joint in lesser toe deformities with an angulated intramedullary implant.

Background: Hammertoe and claw toe are among the most common foot deformities. Proximal interphalangeal (PIP) joint realignment can be performed using specifically designed intramedullary implants. The aim of this study was to assess the clinical outcome of patients with lesser toes deformities undergoing PIP joint realignment using an intramedullary implant.
