The pertinent literature widely describes ultrasound-guided procedures targeting the retrocalcaneal bursa and the tendon tissue to manage insertional Achilles tendinopathy. Synovial bursae and cutaneous nerves of the superficial retrocalcaneal pad are often overlooked pain generators and are poorly considered by clinicians and surgeons. A layer-by-layer dissection of the superficial soft tissues in the retrocalcaneal region of two fresh frozen cadavers was matched with historical anatomical tables of the textbook Traite d'Anatomie Topographique Avec Applications Médico-Chirurgicales (1909 by Testut and Jacob). An accurate and detailed description of the superficial retrocalcaneal pad with its synovial bursae and cutaneous nerves was provided. Cadaveric dissections confirmed the compartmentalized architecture of the superficial retrocalcaneal fat pad and its histological continuum with the superficial lamina of the crural fascia. Superficial synovial tissue islands have been demonstrated on the posterior aspect of the Achilles tendon in one cadaver and on the posterolateral surface of the tendon in the other one. Digitalization of the original anatomical tables of the textbook Traite d'Anatomie Topographique Avec Applications Médico-Chirurgicales (1909 by Testut and Jacob) showed five potential locations of the superficial calcaneal bursa and a superficial retrocalcaneal nerve plexus within the Achilles tendon-fat pad interface. In clinical practice, in addition to the previously described interventions regarding the retrocalcaneal bursa and the tendon tissue, ultrasound-guided procedures targeting the synovial and neural tissues of the superficial retrocalcaneal pad should be considered to optimize the management of insertional Achilles tendinopathy.

INTRODUCTION: No comprehensive treatise on the early history of fractures of posterior malleolus (PM) has yet been published, and many substantial discoveries have fallen into oblivion-particularly if not having been published in English originally. MATERIALS AND METHODS: Literature search was performed in original publications and historical sources. RESULTS: Early history of PM fractures from their first description up to the beginnings of their operative treatment may be divided into three basic periods, covering the era between 1828 and 1940. In the pre-radiological period (1828-1895), description of PM injuries was based merely on the autopsy findings in deceased patients. The first mentions of this injury were published by the British authors. In the radiologic period (1899-1916), the x-ray examination started a revolution also in diagnostics of ankle fractures, with the first radiographs performed as early as in 1899. Radiographic examination had subsequently become an integral part of the diagnostics of these injuries and initiated a number of significant studies of PM fractures. The first detailed mention of a PM injury may be found in the French and German literature. The period of early operative treatment (1918-1940), i.e., open reduction and internal fixation of PM, was started by the younger post-WWI generation, primarily the French surgeons, represented by Gaston Picot. His operative technique and the first six cases treated operatively between 1918 and 1921 were described in 1921 by Edouard Huc. Picot himself published his technique in great detail in 1923. CONCLUSION: The early history of diagnostics and treatment of PM fractures witnesses the remarkable body of knowledge gathered about that topic by numerous visionary surgeons predominantly French and German surgeons immediately before and after World War I. They substantially contributed to the radiological examination and operative treatment of this injury.

Trigger finger (TF), also known as stenosing flexor tenosynovitis, is a common pathology of the fingers causing functional deficit of the hand. In recent years, new therapeutic approaches such as extracorporeal shock wave therapy (ESWT) and ultrasound-guided (USG) procedures have joined the most traditional conservative treatments as the adaptation of daily activities involving the affected hand and the orthosis. Likewise, the ultrasound (US) examination of the affected finger using modern high-frequency probes has progressively become part of the comprehensive assessment of patients with TF coupled with the medical history, the physical examination, and the functional scales. In this sense, considering the technological advances in both diagnostic and therapeutic fields, the non-surgical strategies have progressively grown defining a rehabilitation panel more complex than in the past. The present manuscript aims to provide an updated practical guide for clinicians and surgeons reviewing the state-of-art of both the assessment and the treatments of patients with TF to plan tailored rehabilitation management taking advantage of the matching of traditional and novel techniques.

OBJECTIVE: The aim of the present study was to illustrate the (potential) diagnostic role of high resolution US images in assessing the elementary lesions of dactylitis. METHODS: Using high-frequency US machines/probes, we matched the micro-anatomical cadaveric architecture of the digit with multiple sonographic findings of dactylitis. High-sensitive color/power Doppler assessments have also been performed to evaluate the digital microvasculature. DISCUSSION: Modern US equipment/features guarantee prompt and in-depth B-mode and color/power Doppler imaging of tiny anatomical structures of the digit which are usually not properly visible with standard US machines. More specifically, hypervascularization of the digital subcutaneous tissue, fibrous pulleys of flexor tendons, dorsal synovial pads as well as pathological changes of the distal entheseal anchorage network can be accurately detected. CONCLUSION: In clinical practice, high-end US equipment can be used to accurately assess the digits in patients with dactylitis. This way, simple and convenient sonographic diagnosis of different elementary lesions can be timely established.
AIM: To propose a standardized, high-resolution ultrasound (US) protocol to assess the patellar tendon-Hoffa fat pad interface (PTHFPI) in patients with (proximal) patellar tendinopathy (PPT). METHODS: Using a high-frequency transducer and a high-level machine, we matched the cadaveric and histological microarchitecture of the PTHFPI with multiple sonographic patterns of patients with PPT. Likewise, high-sensitive color/power Doppler assessments were also performed to evaluate the microcirculation of the soft tissues beneath the patellar tendon. RESULTS: Modern US equipment allows for detailed assessment of the potential pain generators located inside the PTHFPI in patients with PPT. They include anterosuperior portion of the Hoffa body and the loose connective tissue of the deep paratenon with its microvascular plexus. CONCLUSIONS: In patients with PPT, accurate sonographic assessment of the PTHFPI can be performed using adequate technological equipment. Accordingly, tailored ultrasound-guided interventions can also be planned if/when clinically indicated.

PURPOSE: Discrepancy between the morphology of the acetabular margin and the design of hemispheric acetabular cups used in total hip arthroplasty may produce postoperative hip pain due to an iliopsoas impingement at the iliopsoas notch. This study aimed to determine the anatomical features of the iliopsoas notch in the Central European sample, and to test whether the morphology of the proximal femur affects the size of the iliopsoas notch. METHODS: The sample was composed of 40 matched pairs of dry hip bones and corresponding femora. The depth and length of the iliopsoas notch were measured and correlated with the available demographic data. The anthropometric parameters of the proximal femur were calculated using image-analysis software, and their association with the measurements of the iliopsoas notch was tested. RESULTS: The iliopsoas notch was present in all specimens and featured four morphological configurations: curved (61.3%), angular (16.2%), irregular (16.2%), and straight (6.3%). Its size was found to be larger in males (P = 0.014 for depth, P < 0.001 for length). No significant difference existed between the sides. The height and age of the specimens did not correlate with the size of the iliopsoas notch. Furthermore, neither the femoral neck version, the lesser trochanteric version, nor the angle between the neck of the femur and the lesser trochanter influenced the dimensions of the iliopsoas notch. CONCLUSION: The iliopsoas notch is a consistent landmark of the acetabulum, although its anatomical appearance is widely variable. The iliopsoas notch arrangement cannot be predicted perioperatively based on the morphology of the proximal femur. The various shapes and sex-related differences detected in this study could be used for designing new hip implants or could be utilized during cup positioning in total hip arthroplasty.

INTRODUCTION: German-speaking surgeons have left a deep imprint on the history of diagnostics and treatment of proximal femur fractures. Some of the studies published in German have fell into oblivion, others are cited until today, although sometimes quite inaccurately. The cause of such inaccuracies are citations from secondary sources due to unavailability of the original or inability to read it because of a language barrier. In the current literature, globally predominated by English articles, the "German history" of treatment of proximal femur fractures remains undervalued. The aim of the present article is to point out its contribution. MATERIALS AND METHODS: Literature search was performed in original publications and historical sources. RESULTS: The German-speaking surgeons have considerably contributed to the development of the treatment of proximal femur fractures. The analyzed period between 1847 and 1970 may be divided into three basic periods. In the first period (1847-1896), the German-speaking surgeons (Langenbeck, Trendelenburg, König, Heine, Dolinger) were the first worldwide to start treating the fractures of proximal femur operatively. In the second period (1897-1935), mainly in the 1930s, the initiative in Europe was taken over by surgeons publishing studies in France and in Belgium. Overseas, American surgeons were coming to the forefront. In Germany, only Pauwels developed the first biomechanical classification of femoral neck fractures. In the third period (1936-1970), mainly in the 1940s and 1950s, implants were designed (Pohl, Künstcher), based on close collaboration between German engineers and surgeons, that served as a model for a dynamic hip screw and a proximal femoral nail, which are currently the implants of choice in the treatment of trochanteric fractures. CONCLUSION: The historical contribution of German-speaking surgeons to understanding the issue of proximal femur fractures and their operative treatment is far more significant than presented in the historical studies published in English.
The Achilles tendon (AT) is the strongest tendon of the human body. The knowledge of AT anatomy is a basic prerequisite for the successful treatment of acute and chronic lesions. The structure of the AT results from a complicated fusion of three parts: the tendons of the medial and lateral gastrocnemius and the soleus muscles. From proximal to distal, the tendon fibers twist in a long spiral into a roughly 90° internal rotation. The tendon is narrowest approximately 5-7 cm above its calcaneal insertion and from there it expands again. The topography of the footprints of the individual AT components reflects the tendon origins. The anterior (deep) AT fibers insert into the middle third of the posterior aspect of the calcaneal tuberosity, the posterior (superficial) fibers pass over the calcaneal tuberosity and fuse with the plantar aponeurosis. A deep calcaneal bursa is interposed between the calcaneal tuberosity and the AT anterior surface. The AT has no synovial sheath but is covered along its entire length with a sliding connective tissue, the paratenon which is, however, absent on its anterior surface. The AT is supplied by the posterior tibial artery (PTA) and the peroneal artery (PA). Motor innervation of the triceps surae muscle is provided by fibers of the tibial nerve which also gives off sensitive fibers for the AT. Sensitive innervation is also provided via the sural nerve. The sural nerve crosses the AT approximately 11 cm proximal to the calcaneal tuberosity. The forces acting on the AT during exercise may be up to 12 times the body weight. Physiological stretching of AT collagen fibers ranges between 2% and 4% of its length. Stretching of the tendon over 4% results in microscopic failure and stretching beyond 8% in macroscopic failure.

Insertional Achilles tendinopathy is an umbrella medical term referring to pain and swelling on the posterior aspect of the calcaneus. High-resolution ultrasound imaging is commonly used in daily practice to assess the pathological changes of the Achilles tendon, cortical bone of the calcaneus, and soft tissues located inside the retrocalcaneal space to optimize the management of relevant patients. To the best of our knowledge, a standardized ultrasound protocol to evaluate the retrocalcaneal bursal complex is lacking in the pertinent literature. In this sense, our step-by-step sonographic approach is intended to be an easy and ready-to-use guide for sonographers/physicians in daily practice to assess this anatomical complex in patients with Achilles tendinopathy. Needless to say, the peculiar histological features of this V-shaped synovial/fibrocartilaginous bursa surrounding the posteroinferior wedge of the Kager's fat pad and the retrocalcaneal space make the examination challenging.
