REVIEW
Markus Walther
BACKGROUND: The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. DIAGNOSTICS: Loaded x‑rays of the foot in three planes as well as the hindfoot alignment view enable evaluation of the axis of the foot under static loading conditions. The posterior tibial tendon can be imaged with ultrasound and magnetic resonance imaging (MRI)...

A 50-year-old lady presented with a right foot mass and pain for 1year. Magnetic resonance imaging showed a 3.9×3.2×5cm mass on plantar side of the forefoot deep to the major flexor tendons and plantar aponeurosis and inferior to 1st-4th metatarsals. The mass extended dorsally through the intermetatarsal space to the foot dorsum. Ultrasound guided biopsy was performed, which confirmed it was a fibroma. This case was further complicated by pathological fracture of the 3rd metatarsal. It was resected through a dorsal incision and surgical dislocation of the 2nd and 3rd tarsometatarsal joints...

Plantar fibromatosis is a rare benign but often locally aggressive tumor of the plantar aponeurosis. Nonsurgical treatment is the first line of treatment for symptomatic lesions. Because of the high recurrence rate associated with surgical treatment, operation is indicated only when the lesions are highly symptomatic and conservative measures fail or the diagnosis is in question. The purpose of this technical note is to report the details of endoscopic subtotal fasciectomy. This may reduce the risks of skin necrosis and dehiscence, infection, and formation of painful hypertrophic scars...

BACKGROUND: Radiofrequency (RF) treatment is a minimally invasive procedure that has been used for more than 3 decades in treating various chronic pain syndromes. Conventional (continuous) RF treatment occasionally results in worsening or even initiating a new type of pain. The use of pulsed radiofrequency (PRF), which has a non- or minimally neurodestructive neuromodulatory effect, serves as an alternative to conventional RF therapy in many medical situations. OBJECTIVES: To evaluate the effect of applying PRF for 6 minutes vs...

OBJECTIVES: Part of the psoriasis patients with musculoskeletal complaints will have inflammation of the entheses. Entheseal inflammation is difficult to assess by clinical examination only. Therefore, we aimed to determine the frequency of clinically relevant ultrasound inflammation at the most commonly assessed entheses (MASEI; Madrid Sonographic Enthesis Index) in primary care psoriasis patients with one or more tender entheses. METHODS: Adult primary care psoriasis patients with musculoskeletal complaints (tender enthesis or arthritis at physical examination) had an ultrasound examination of seven entheses according to the MASEI...

The differential diagnosis for a midfoot or forefoot mass or mass-like abnormality includes several common benign and malignant pathologies. Evaluation with imaging can often provide a diagnosis, or at least several likely etiologies, and guide management. Determining if a mass is cystic or solid with ultrasound or MRI can limit the differential diagnosis. Identifying the abnormality at a specific anatomical site, such as a bursa, peripheral nerve, plantar aponeurosis, or tendon, can often suggest a correct diagnosis...

BACKGROUND: Detailed investigation of the vasculature of the lateral aspect of the foot has rarely been presented. However, harvesting the flap in this area to cover defects of the foot and hand is highly important. Repair of soft-tissue defects at the forefoot remains a challenge in reconstructive surgery. This study explores the characteristics of the distal-based lateral dorsal cutaneous neuro-lateral plantar venofasciocutaneous flap pedicled with the lateral plantar artery perforator of the fifth metatarsal bone to establish a repair procedure for ulcers or defects in the forefoot region...

REVIEW
L Döderlein, C Dussa
BACKGROUND: The apophysis of the calcaneal bone forms an insertional region for the strong plantarflexors with the Achillis tendon and serves as an origin for the plantar aponeurosis and the short intrinsic foot muscles. Both components create a tendinous sling whithin which the apophysis acts as a pivot, which functions when it runs a straight course and its tension is adequate. This mechanism results in combined tractional and compressional forces which work together with the ground reaction forces during gait as molding elements of the calcaneous bone...

BACKGROUND: In recent years, an increasing number of runners prefer jogging barefoot or in minimalistic shoes. The aim of this study was to compare the distribution of plantar pressure during jogging barefoot, in minimalistic shoes, or in shoes with cushioned soles, as these forces modulate the risk of injury. METHODS: The study included nine men aged between 24 and 25 years, who engaged in long-distance running. The plantar pressure of three foot zones (forefoot, midfoot, and hindfoot) was examined with WIN-POD electronic podometer during running barefoot, in minimalistic shoes, or in shoes with cushioned soles...

During locomotion, the lower limb tendons undergo stretch and recoil, functioning like springs that recycle energy with each step. Cadaveric testing has demonstrated that the arch of the foot operates in this capacity during simple loading, yet it remains unclear whether this function exists during locomotion. In this study, one of the arch׳s passive elastic tissues (the plantar aponeurosis; PA) was investigated to glean insights about it and the entire arch of the foot during running. Subject specific computer models of the foot were driven using the kinematics of eight subjects running at 3...

BACKGROUND: It is believed that the anti-inflammatory activity of medicines is closely related to their antioxidant activity. However, in clinical practice rigorous evidence-based medicine approach fails to reveal important effects of antioxidants on patient important outcomes in inflammatory disorders, as has been shown by a number of Cochrane reviews [1-3]. OBJECTIVE: To evaluate anti-inflammatory and antioxidant effects of newly developed pharmacological agents: dimephosphone and its structural analogues ephorane and mephoprane, and xymedon, in comparison with prednisolone and etidronate in experimental animal model of adjuvant arthritis...

Abductor hallucis (AH) is an intrinsic muscle of sole of the foot. It is commonly used in the coverage of ankle and heel defects and chronic nonhealing ulcers of the foot; its use is reported to have a favorable long-term outcome. The muscle's apt bulk and size, its simple surgical isolation, absence of donor-site defect, unvaried anatomy, and long neurovascular pedicle are some of the advantages that make it a promising muscle flap. During routine cadaver dissection in the Department of Anatomy of Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry, India, we identified an anatomical variation in AH in both feet of a 45-year-old embalmed male Indian cadaver...

Mechanical loading of the Achilles tendon during isolated eccentric contractions could induce immediate and region-dependent changes in mechanical properties. Three-dimensional ultrasound was used to examine the immediate effect of isolated eccentric exercise on the mechanical properties of the distal (free tendon) and proximal (gastrocnemii) regions of the Achilles tendon. Participants (n = 14) underwent two testing sessions in which tendon measurements were made at rest and during a 30% and 70% isometric plantar flexion contractions immediately before and after either: (a) 3 × 15 eccentric heel drops or (b) 10-min rest...

Using a cross-sectional design, the purpose of this study was to determine how pennate gastrocnemius medialis (GM) muscle geometry changes as a function of adolescent age. Sixteen healthy adolescent males (aged 10-19 years) participated in this study. GM muscle geometry was measured within the mid-longitudinal plane obtained from a 3D voxel-array composed of transverse ultrasound images. Images were taken at footplate angles corresponding to standardised externally applied footplate moments (between 4 Nm plantar flexion and 6 Nm dorsal flexion)...

Tendinous and subcutaneous xanthomas are most commonly associated with primary hyperlipidemia. Xanthomatosis caused by cholesterol deposition can be a high risk marker for cardiovascular disease related to premature atherosclerosis; thus, early recognition of this diagnosis may reduce mortality and morbidity. Achilles tendon involvement is most common, followed by the extensor tendons of the hand and elbow. We present an exceptional case of tendinous and tuberous xanthomas, with intraoperative and histologic correlation, in a 34-year-old female manifesting with xanthomatous deposits of nearly all ankle tendons, plantar aponeurosis, extensor tendons of the hands, and various locations within the integumentum...
