Range of Flexion Improvement in Degenerative Stages of the First Metatarsophalangeal Joint () with Cross-Linked Hyaluronic Acid: A Cadaveric Study.

Background: Viscosupplementation consists of intraarticular hyaluronic acid injections applied to treat pain and improve joint mobility. The objective of the study was to analyze the improvement of the range of mobility of the first metatarsophalangeal joint with a single dose of cross-linked hyaluronic acid.

Methods: Ten fresh frozen specimens of feet sectioned below the knee were selected.

Good Short- and Mid-term Outcome After Cross-Linked Hyaluronic Acid Infiltration for Hallux Rigidus: A Case Report.

We report a first case of hallux rigidus successfully treated in an elderly patient by intra-articular infiltration of cross-linked hyaluronic acid (HA) 21 mg/mL with mannitol (Desirial Plus) and review the previous literature on the different compositions of HA infiltrative treatment applied to hallux rigidus. A 77-year-old female patient with moderate unilateral pain of 6 months of evolution and stiffness of the movement of the first metatarsophalangeal joint of the left foot, corresponding to grade 2 of the classification proposed by Coughlin and Shurnas. The objective of the study was to perform a pilot test to (a) evaluate the correct technique of intra-articular infiltration as well as (b) the use of a commercial cross-linked HA 21 mg/mL with mannitol, to a voluntary patient diagnosed with hallux rigidus.

Assessment and indicators of hallux limitus related with quality of life and foot health in school children.

Background: Functional Hallux Limitus (FHL) is a dynamic foot dysfunction characterized by a limitation of hallux dorsiflexion when the first metatarsal head is under load. FHL plays a role in the development of osteoarthrosis in the first metatarsophalangeal joint (IMTPJ). Forefoot disorders can significantly impact an individual's quality of life, leading to dysfunction and pain.

Hallux Limitus Influence on Plantar Pressure Variations during the Gait Cycle: A Case-Control Study.

Background: Hallux limitus is a common foot disorder whose incidence has increased in the school-age population. Hallux limitus is characterized by musculoskeletal alteration that involves the metatarsophalangeal joint causing structural disorders in different anatomical areas of the locomotor system, affecting gait patterns. The aim of this study was to analyze dynamic plantar pressures in a school-aged population both with functional hallux and without.

Analysis of Static Plantar Pressures in School-Age Children with and without Functional Hallux Limitus: A Case-Control Study.

Background: The presence of hallux limitus in adulthood is frequently encountered in clinical practice, generating other biomechanical, structural, and functional compensations in dynamics secondary to blockage of the main pivot in the sagittal plane, the first metatarsophalangeal joint. In addition, the presence of functional hallux limitus (FHL) in school-age children is also increasing. Currently, there is a lack of scientific literature about this condition in the pediatric population, and early diagnosis is necessary to reduce future biomechanical disorders and avoid the development of foot arthritis.

Subungual Exostosis .

Background: The coexistence of deformity of the nail bed and subungual exostosis (SE) is a frequent finding in podiatric practice in the fourth and fifth decades of life. However, it has been described by other specialists as being an uncommon osteocartilaginous tumor most prevalent during the second and third decades of life. This study attempts to determine the causes of this discrepancy.
