Talipes Equinus Deformity Caused by Fibrous Gastrocnemius Muscle Contracture After Direct Contusion in Football Players: Report of Two Cases.

J Foot Ankle Surg 2020 Jul - Aug;59(4):816-820

Professor, Department of Orthopaedic Surgery, Fukushima Medical University School of Medicine, Fukushima, Japan.

Two main causes of gastrocnemius contracture have been considered: 1) congenital deformities in pediatric patients, such as limb-length discrepancy, cerebral palsy, flatfoot, and clubfoot; and 2) secondary conditions such as immobilization for trauma or a nonfunctional limb. Talipes equinus deformity caused by fibrous gastrocnemius contracture after a direct muscle contusion is extremely rare. We describe 2 cases of talipes equinus deformity caused by fibrous gastrocnemius muscle contracture after a direct contusion in football players. Read More

The symptomatic adult flatfoot: Is there a relationship between severity and degree of pre-existing arthritis in the foot and ankle?

Foot (Edinb) 2020 Jun 28;43:101664. Epub 2020 Jan 28.

Department of Orthopaedic Surgery, Southmead Hospital, Bristol, United Kingdom.

Background: The acquired adult flatfoot deformity (AFFD) is a potentially debilitating foot condition with a prevalence thought to be between 3 %-10 %. To the authors' best knowledge, no association has been described between severity of AFFD and degree of pre-existing ankle or foot arthritis. The degree and pattern of preexisting ipsilateral arthritis of the foot and ankle was investigated in those with symptomatic AFFD presenting to hospital. Read More

Excision Arthroplasty With Interpositional Achilles Tendon Autograft: A Novel Approach to Talonavicular Joint Osteoarthritis Associated With Ankle Arthrodesis.

J Foot Ankle Surg 2020 Mar - Apr;59(2):440-444

Professor, Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, Tokyo, Japan.

Talonavicular joint arthritis is a great concern after ankle fusion. Although arthrodesis is the gold standard treatment for this complication, it could initiate a vicious cycle of further adjacent joint arthritis. An alternative that may delay or eliminate the need for arthrodesis is excision arthroplasty; however, there are only a few reports on its application on a talonavicular joint. Read More

Pediatric Flatfeet-A Disease Entity That Demands Greater Attention and Treatment.

Front Pediatr 2020 11;8:19. Epub 2020 Feb 11.

Hospital de Niños Victor J. Vilela, Rosario, Argentina.

Pediatric flatfoot is a common deformity. Unfortunately, the common opinion has been that most children with this faulty foot structure will simply out-grow it, despite no radiographic evidence to support this claim. Every step on a deformed foot leads to excessive tissue strain and further joint damage. Read More

Stiffness of the human foot and evolution of the transverse arch.

Nature 2020 03 26;579(7797):97-100. Epub 2020 Feb 26.

Mathematics Institute, University of Warwick, Coventry, UK.

The stiff human foot enables an efficient push-off when walking or running, and was critical for the evolution of bipedalism. The uniquely arched morphology of the human midfoot is thought to stiffen it, whereas other primates have flat feet that bend severely in the midfoot. However, the relationship between midfoot geometry and stiffness remains debated in foot biomechanics, podiatry and palaeontology. Read More

Weight-bearing CT Scans in Foot and Ankle Surgery.

J Am Acad Orthop Surg 2020 Feb 21. Epub 2020 Feb 21.

From the Foot and Ankle Service, Department of Orthopedic Surgery, Hospital for Special Surgery, New York, NY.

Weight-bearing CT (WBCT) scans of the foot and ankle have improved the understanding of deformities that are not easily identified on radiographs and are increasingly being used by orthopaedic surgeons for diagnostic and preoperative planning purposes. In contrast to standard CT scans, WBCT scans better demonstrate the true orientation of the bones and joints during loading. They have been especially useful in investigating the alignment of complex pathologies such as adult-acquired flatfoot deformity in which patients have been found to have a more valgus subtalar joint alignment than in a normal cohort and high rates of subfibular impingement.

Obesity and falls in older women: Mediating effects of muscle quality, foot loads and postural control.

Gait Posture 2020 03 1;77:138-143. Epub 2020 Feb 1.

Faculty of Physical Education, University of Brasilia, Brazil.

Background: Obesity is associated with an increased risk of falls in older women. However, it is not certain whether factors commonly associated with obesity and falls mediate this risk.

Research Question: Do lower-limb muscle quality, foot loads and postural control mediate the relationship between obesity and falls in women aged 60 years and older?

Methods: At baseline, 246 female participants underwent obesity screening (BMI≥30 kg/m²), and measurements of muscle quality (isokinetic dynamometer and dual-energy X-ray absorptiometry), foot loads (pressure platform) and postural balance (force platform). Read More
