The medial gastrocnemius is the most commonly injured muscle in the calf, and while traumatic lesions of the medial gastrocnemius are frequently described in the medical literature and clinical and sonographic diagnoses are easy, those of the soleus are less easily recognisable clinically or by sonography. We present a case of traumatic lesions of the medial gastrocnemius, diagnosed clinically and with ultrasound, while MRI also detected two lesions of the soleus. The case presented and the review of the literature highlight how clinical and ultrasound examinations can lead to misunderstandings about traumatic injury to the soleus.

Knee joint position influences ankle torque, but it is unclear whether the soleus compensates to counteract the reductions in gastrocnemius output during knee-flexed versus knee-extended plantarflexions. Therefore, the purpose of this study was to determine the effects of knee joint position and plantarflexion contraction velocity on ankle plantarflexion torque and electromyography activity of the medial gastrocnemius and soleus in healthy young adults. Healthy male participants (n=30) performed concentric plantar flexions in a custom-built dynamometer from 15° dorsiflexion to 30° plantarflexion at gradually increasing velocities during each contraction at 30, 60, 120, 180, and 210° s-1 in a supine position with the knee fully extended and while kneeling with the knee fixed in 90° flexion.

Background: Emerging research underscores the significance of midlife obesity, defined by a BMI of 30 kg/m or higher in persons age 40-60 years, as a risk factor for Alzheimer's disease (AD) in later life. Due to the various properties of each body component, it is important to characterize the neurodegenerative effects of fat within the muscle, known as a predictor of metabolic health and cognition. We investigated the relationships between thigh total fat-to-muscle ratio (FMR) and brain cortical thickness in cognitively normal midlife individuals.

Plantar fasciitis (PF), a common cause of heel pain, primarily results from inflammation of the plantar fascia due to excessive strain. Its complex pathophysiology, influenced by various biomechanical factors, has led to the development of diverse surgical techniques. Most of these techniques, when used in isolation, have shown benefits in treating refractory PF.

The use of the gastrocnemius muscle flap has become an excellent choice for coverage of Knee Defects. However, the surgical management of gastrocnemius muscle flap in the injuries of the popliteal artery remains a challenging therapeutic problem. The purpose of this manuscript is to present a case of a successful knee gastrocnemius flap in a patient with popliteal artery injuries.

sarcoma is rare and its clinical features remain unclear. Given the similarity in presentation, it is possible that previously reported cases of Ewing-like adamantinoma may have been sarcoma. The present case report describes a tumor in a 55-year-old man that was originally thought to be a Ewing-like adamantinoma, but was recently found to be an sarcoma following direct sequencing.
