Artificial ankle joint replacement surgery is an important treatment for patients with ankle osteoarthritis (OA). Estimation of the pre-deformed ankle bones shapes are a key factor in artificial joint replacement surgery, and the surgeon can achieve highly satisfactory outcomes for patients such as less pain and sufficient function with an alternative ankle joint. However, the relationship between the bone shape deformation process and stage of the disease remains unclear. In this study, we inve...
A Novel Approach to Post-Traumatic Foot and Ankle Pains using Percutaneous Ultrasound Guided Cryoneurolysis: A Case Report
David H Sherwood, DO, Jason-Flor V Sisante, PhD and Neil A Segal, MD, MS
Article Type: Case Report | First Published: September 20, 2019
Cryoneurolysis is a minimally invasive, low side effect profile, evidence-supported intervention currently with FDA approval to produce lesions in peripheral nervous tissue, including for relief of pain associated with knee osteoarthritis. The mechanism of action on a peripheral nerve is temporary axonal signal disruption via Wallerian degeneration. While the axon and myelin sheath degenerate, the endoneurium, perineurium and epineurium are unaffected. Schwann cells and macrophages clear debris,...
Extreme Thrombocytosis Resulting from Minimally Invasive Foot Surgery with Forefoot Necrosis: A Rare Case Report
Cuervas-Mons Manuel, Alvarez Baena Lucia, Garcia Ruano Angela and Arnal Burro Javier
Article Type: Case Report | First Published: September 19, 2019
Essential thrombocythemia is a chronic myeloproliferative syndrome characterised by excessive proliferation of platelets and megakaryocytes, with a relatively favourable course. We present a case of extreme thrombocytosis resulting from minimally invasive foot surgery with forefoot necrosis. A 72-year-old female patient presented with hallux valgus and metatarsalgia. A platelet count of 560,000/ µL was detected as an unexpected finding. Minimally invasive surgery was performed, and in the first...
Plantar Fasciitis Rupture - Who is the Culprit?
Article Type: Case Report | First Published: August 26, 2019
The plantar fascia is an important structure in the foot, which helps, stabilizes the arch of the foot during motion and provides shock absorption when the foot hits the ground. Inflammation of the plantar fascia has been high in incidence, with multiple factors attributed to it. However, occurrence of the plantar fascia rupturing is not common. Corticosteroid injection to the plantar fascia has long been advocated as the major cause of this. Nonetheless, in recent literatures, corticosteroid in...
Freiberg's Infraction in a Geriatric Patient - A Case Report
Daniel Pollack, DPM, FACFAS
Article Type: Case Report | First Published: August 17, 2019
Foot pain is debilitating and common, especially in the geriatric population. It causes difficulty, or an inability, to ambulate which may lead to further issues such as weight gain, reliance on others for assistance, and imbalance which can lead to falls. It is important to consider Freiberg's infraction as a cause of foot pain in the elderly, even if it normally occurs in younger patients. Freiberg's infraction (also known as Freiberg's disease) is premature bone death, or osteonecrosis, of mo...
Surgical Repair of an Unstable Third Metatarsophalangeal Joint Dislocation via Direct Plantar Plate Repair: A Simple and Effective Technique
Christopher W Kinter, MD, Kevin J Kinter, MS and Christopher W Hodgkins, MD
Article Type: Case Report | First Published: August 12, 2019
Traumatic dislocation of a lesser metatarsophalangeal (MTP) joint is a rare case for a foot and ankle surgeon to encounter. These dislocations can be difficult to reduce due to the surrounding connective tissues that may be interposed in the joint space. These include the plantar plate, deep transverse metatarsal ligament, flexor tendons, and lumbricals. When the clinician is unable to reduce the phalanx, surgery is required to prevent sequelae such as further swelling, ecchymosis, joint damage,...
Z-Calcaneal Osteotomy: Radiographic Assessment of Correction in the Valgus Hindfoot
Daniel Dawson, A Walls and J Wong
Article Type: Original Article | First Published: June 24, 2019
Elective reconstruction in the valgus hindfoot is a complex and varied field of orthopaedic surgery. Often multiple procedures, both bony and soft tissue are required. The surgical aims are to create a plantigrade foot, restore hindfoot alignment and re-create the medial longitudinal arch in an attempt to allow more normal biomechanical function. Invariably a calcaneal osteotomy is required to correct hindfoot alignment. There are various methods of performing a calcaneal osteotomy....
Changes in Dynamic Plantar Pressure for Children with Tarsal Coalition as Compared to Normal Children
Brian Curtin, DO, Xue-Cheng Liu, MD, PhD, Roger Lyon, MD and Scott Van Valin, MD
Article Type: Research Article | First Published: May 10, 2019
One of effective therapeutic treatment involves the use of inserts to alter the foot biomechanical alignment and reduce the pain. It is essential to select an appropriate insert based upon foot functions by dynamic plantar pressure measurements. The goal of this study was to evaluate children's kinetic abnormalities in feet with tarsal coalition using plantar pressure measurements. The design of this study was a prospective cohort with normal control, which is considered as Level 3 Evidence....
Extracorporeal Shock Wave Therapy (ESWT) for Refractory Fractures at the Fifth Metatarsal Base

Article Type: ORIGINAL ARTICLE | First Published: March 22, 2019
A fifth metatarsal base fracture is common in athletes and is often difficult to treat. Refractory cases are often managed surgically with screw fixation or bone grafts, but such procedures are extremely invasive. Recently, positive results have been reported from the use of extracorporeal shock wave therapy (ESWT) for stress fractures or delayed fracture union. We report on our experience with ESWT used in five cases of refractory fifth metatarsal base fracture where bone union had not been ach...

Diffusion Weighted Magnetic Resonance Imaging of the Achilles tendon and Related Pathology: Qualitative & Quantitative Investigation
Muna Al Mulla, PhD, Allison McGee, MSc, Prof. Stephen Eustace, and Louise Rainford, PhD
Article Type: RESEARCH ARTICLE | First Published: February 28, 2019
Diffusion-weighted imaging (DWI) is an MRI technique that has shown to be a very promising in facilitating the differentiation of subtle pathological changes within different tissue. However, to date, a conclusive physical basis for the signal contrast on DWI of the Achilles tendon (AT) is yet to be available in literature. The purpose of this work is to evaluate the diagnostic impact of echo planar DWI in distinguishing normal and abnormal AT using ADC mapping as a qualitative and quantitative ...

Article Type: ORIGINAL ARTICLE | First Published: February 18, 2019
Hallux valgus (HV) is a common deformity of the forefoot in which a deviation of the first metatarsophalangeal joint arises. HV has been described to be characterized by a number of structural factors including radiographic angles, metatarsal length, metatarsal head shape, sesamoid position, first metatarsocuneiform joint flexibility and pes planus. The etiology is not fully resolved. However, HV is associated with gender, age and family history. Moreover, it is limited to shoe-wearing cultures ...

Jun Zhang, Dapeng Hao, Chuanyu Zhang and Shaohua Wang
Article Type: Case Report | First Published: February 13, 2019
The accessory soleus muscle is a rare anatomical variant that usually occurs in adolescents or young adults. And it may manifest as an exertional ankle pain and swelling or as an asymptomatic posteromedial mass. However sometimes it may be mistaken as a soft tissue tumor at the ankle. The purpose of this study is to heighten awareness about the existence of accessory soleus muscle in a swelling at the posteromedial aspect of the ankle and to reduce the failure to recognize this muscle in MRI....
