BACKGROUND: The Effect of Surgery and Compression on Healing and Recurrence (ESCHAR) trial previously reported that patients with venous leg ulcers treated with saphenous stripping experienced a significantly reduced incidence of ulcer recurrence compared with patients treated with compression therapy. Most patients with leg ulcers and saphenous insufficiency are currently treated with endovenous thermal ablation (EVTA), but little information is available on the long-term results after EVTA in Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) clinical class 5 (C5) and class 6 (C6) patients...

The study was carried out on 50 human lower legs obtained during autopsies (KBET: 122.6120.315.2016). The anatomy of the joint was studied using classical anatomical description methods. Based also on literature we have reviewed the current knowledge on the inferior tibiofibular joint blood supply considering the important clinically aspect - vascular density. Authors of this paper postulate relatively low vascular density of the region described and potential worse condition for healing in case of injury or after surgical procedures performed...

Kaissar Yammine, Mirela Erić
Being considered an exclusive human structure for a long time, fibularis tertius (FT) is believed to have a secondary function of foot dorsiflexion and eversion. This study is an attempt to approach the issue from an anatomical perspective. A systematic literature search identified 35 studies (7601 legs) which met the inclusion criteria. The weighted results of FT presence were as follows: an "adult cadaveric" frequency of 93.2% and a clinical frequency of 80%. The most common FT origin and insertion sites were the distal half of fibula and the base of the 5th metatarsal, respectively...

Humans are unable to survive low temperature environments without custom designed clothing and support systems. In contrast, certain penguin species inhabit extremely cold climates without losing substantial energy to self-heating (emperor penguins ambient temperature plummets to as low as -45°C). Penguins accomplish this task by relying on distinct anatomical, physiological and behavioral adaptations. One such adaptation is a blood vessel heat exchanger called the 'Rete Tibiotarsale' - an intermingled network of arteries and veins found in penguins' legs...

The skin is the most requested product of ratite slaughter and 'first-rate' ratite's skin has a high economic market. Ostrich hide is tanned in South Africa and sold all over the world. Besides, the ostrich meat is considered a niche production in the marketplace, thus allowing for another pro t for the ostrich breeding. Theorical analysis of skinning process has been carried out, and an automatic measurement system has been designed to record the drawing-force on the animal's body during skinning tests. The aim of this study was to indentify the best animal position and provide values of drawing-force in order to design a speci c machine for ostrich skinning...

We present the case of a 46-year-old commercial pilot with a history of unilateral leg swelling following a flight to Geneva. Although initial clinical examination suggested a deep vein thrombosis, the swelling only partially resolved with anticoagulation and further imaging suggested the presence of adventitial cystic disease (ACD). The patient underwent initial anticoagulation to allow any thrombus to be lysed, followed by excision of the ACD from the venous wall and venous reconstruction. Following the excision of the ACD, providing the patient remains asymptomatic and further imaging finds normal venous anatomy, we hope the patient will discontinue anticoagulation and return to flying...

Chronic venous disease is a common disorder associated with a variety of symptoms in later disease stages but also with complications such as venous leg ulcer. This, in turn, has substantial socioeconomic effects and significantly impacts patients' quality of life. While there are a number of diagnostic procedures available, color-flow duplex ultrasound has become the gold standard. As regards therapeutic options, major advances have been made in recent decades. Today, there are alternatives to saphenofemoral ligation and stripping of the great saphenous vein, including endovenous thermal ablation techniques...

The large size of some retroperitoneal tumors and the complex anatomy of the retroperitoneal structures often require en bloc resection of contiguous organs and, sometimes, resection of critical vascular structures. Vascular reconstructive techniques allow reconstruction of major vascular structures, and autologous vein grafting is the preferred option. Although great saphenous vein can be used in select cases, other options must be explored in cases of caliber mismatch between saphenous vein and native vessel...

BACKGROUND: There is an increasing interest in the operative treatment of deltoid ligament disruption in the setting of chronic ankle instability. Understanding the vascular anatomy of the deltoid complex is beneficial when considering operative procedures on the medial ankle and may provide insight into factors that lead to chronic deltoid insufficiency and ankle instability. METHODS: Thirty-two pairs of cadaveric specimens (64 total legs) were amputated below the knee, and the tibialis anterior, tibialis posterior, and peroneal arteries were injected with India ink and Ward's blue latex...

Whether tree canopy habitats played a sustained role in the ecology of ancestral bipedal hominins is unresolved. Some argue that arboreal bipedalism was prohibitively risky for hominins whose increasingly modern anatomy prevented them from gripping branches with their feet. Balancing on two legs is indeed challenging for humans under optimal conditions let alone in forest canopy, which is physically and visually highly dynamic. Here we quantify the impact of forest canopy characteristics on postural stability in humans...

The body temperature of cattle varies regularly with both the reproductive cycle and disease status. Establishing an automatic method for monitoring body temperature may facilitate better management of reproduction and disease control in cattle. Here, we developed an Automatic Measurement System for Cattle's Surface Temperature (AMSCST) to measure the temperature of metatarsus by attaching a special shell designed to fit the anatomy of cattle's hind leg. Using AMSCST, the surface temperature (ST) on the metatarsus of the hind leg was successively measured during 24 hours a day with an interval of one hour in three tested seasons...

Animals' adaptations to cave habitats generally include elaboration of extraoptic senses, and in insects the receptor structures located on the legs are supposed to become more prominent in response to constant darkness. The receptors for detecting substrate vibrations are often highly sensitive scolopidial sensilla localized within the legs or the body. For troglobitic insects the evolutionary changes in vibroreceptor organs have not been studied. Since rock is an extremely unfavorable medium for vibration transmission, selection on vibration receptors may be weakened in caves, and these sensory organs may undergo regressive evolution...

INTRODUCTION: Modern total hip arthroplasty is largely dependent on the successful preservation of hip geometry. Thus, a successful implementation of the preoperative planning is of great importance. The present study evaluates the accuracy of anatomic hip reconstruction predicted by 2D digital planning using a calcar-guided short stem of the newest generation. METHODS: A calcar-guided short stem was implanted in 109 patients in combination with a cementless cup using the modified anterolateral approach...

AIMS: Modular or custom-made femoral components have been preferred for total hip arthroplasty (THA) in patients with a history of Perthes' disease because of the distortion in the anatomy of the proximal femur. However, it has not been established whether a monobloc cementless stem will fit the distorted proximal femur or whether the results of the procedure are satisfactory in this group of patients. PATIENTS AND METHODS: We reviewed 68 consecutive patients who had undergone THA for childhood Perthes' disease between June 2003 and December 2008...

We present the case of a 15-year-old teenager who sustained an ankle inversion injury while playing American football, which yielded only minimal pain, but also foot numbness and a lateral leg bulge. Magnetic resonance imaging evaluation revealed a proximal peroneal tear. These rare injuries are often associated with compartment syndrome, a surgical emergency, which was ultimately excluded clinically in this patient. Relevant anatomy, mechanism of injury, and clinical manifestations are discussed.

Coarctation of the aorta (CoA) is a well-known congenital heart disease (CHD), which is often associated with several other cardiac and vascular anomalies, such as bicuspid aortic valve (BAV), ventricular septal defect, patent ductus arteriosus and aortic arch hypoplasia. Despite echocardiographic screening, prenatal diagnosis of CoA remains difficult. Most patients with CoA present in infancy with absent, delayed or reduced femoral pulses, a supine arm-leg blood pressure gradient (>20 mm Hg), or a murmur due to rapid blood flow across the CoA or associated lesions (BAV)...

BACKGROUND: Isolated gastrocnemius contracture (IGC) is associated with various foot and ankle pathologies. To address the problem of IGC, a number of gastrocnemius lengthening procedures have been described. Although proximal medial gastrocnemius recession (PMGR) has shown to be an effective operative treatment for IGC, it poses risks to various anatomic structures around the knee joint and requires the patient to be positioned prone. As an alternative, we proposed to release the medial gastrocnemius at the division between the proximal one-third and distal two-thirds of the gastrocnemius muscle to correct equinus contracture, while minimizing risk to other structures...

We propose an automated pipeline for vessel centerline extraction in 3-D computed tomography angiography (CTA) scans with arbitrary fields of view. The principal steps of the pipeline are body part detection, candidate seed selection, segment tracking, which includes centerline extraction, and vessel tree growing. The final tree-growing step can be instantiated in either a semi- or fully automated fashion. The fully automated initialization is carried out using a vessel position regression algorithm. Both semi-and fully automated methods were evaluated on 30 CTA scans comprising neck, abdominal, and leg arteries in multiple fields of view...

PROBLEM AND HYPOTHESIS: Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain. PATIENTS AND METHODS: Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.3) that had healed were included. Foreign patients and those with an associated spinal or acetabular fracture or nonunion were excluded...
