Osteogenesis imperfecta
Osteogenesis imperfecta, also known as brittle bone disease, is a genetic disorder characterized by frequent fractures occurring with minor trauma or no apparent cause. Patients may experience anywhere from a few to hundreds of fractures throughout their lives.
View detailsOsteoporosis
Osteoporosis is a systemic skeletal disease characterized by thinning, brittleness, and porous, sponge-like bones, which increases the risk of fractures. It is commonly observed in individuals over 60 years of age, with a higher prevalence in postmenopausal women.
View detailsMuscle contracture
Muscle contracture refers to a clinical syndrome characterized by specific gaits and signs due to degeneration and contracture of muscle and fascial fibers in the affected area, leading to restricted joint function. The main symptoms include postural deformity in the contracted area, severe pain around the joint, skin depressions, and restricted abduction and adduction of limb joints.
Peripheral nerve injury
Peripheral nerve injury refers to a condition where nerves outside the central nervous system are damaged due to various reasons, leading to symptoms such as sensory disturbances, motor impairment, and nutritional deficiencies in the areas they innervate.
View detailsMuscle atrophy
Muscle atrophy refers to a condition where muscle fibers become thinner and muscle volume decreases due to various causes, leading to reduced muscle strength. It can be classified into neurogenic muscle atrophy, myogenic muscle atrophy, disuse muscle atrophy, and other types of muscle atrophy. Neurogenic and myogenic types are more common. Patients primarily present with reduced muscle volume, muscle weakness, and weight loss. Reduced muscle volume For example, thinning of the limbs; square shoulders due to deltoid atrophy; and thinning and flattening of the palms with prominent bone contours due to hand muscle atrophy. Decreased muscle strength Calf muscle atrophy mainly manifests as difficulty squatting and standing; if it is atrophy of small muscles, it first presents as impaired fine motor skills, such as difficulty writing due to interosseous muscle atrophy in the hand. Craniofacial muscle atrophy mainly presents as difficulty chewing, choking during swallowing, and difficulty extending the tongue; atrophy of the neck and proximal limb muscles mainly presents as difficulty lifting the head, prominent scapulae, and difficulty lifting the limbs. Weight loss When muscle volume significantly decreases, noticeable weight loss will occur.

Peripheral neuropathy is divided into two main categories: neuralgia and neuropathy. Common peripheral neuropathies include trigeminal neuralgia, idiopathic facial paralysis, multiple neuritis (peripheral neuritis), acute infectious polyradiculoneuritis, brachial plexus injury, ulnar nerve injury, radial nerve injury, median nerve injury, tibial nerve injury, common peroneal nerve injury, lateral femoral cutaneous neuritis, sciatica, intercostal neuralgia, etc.

Low back pain refers to pain occurring in the lower back, lumbosacral, or sacroiliac regions, primarily on one or both sides of the waist, which may radiate to the legs. The most common cause of low back pain is mechanical injury due to various factors, such as lumbar sprains. In addition, localized lumbar spine lesions caused by chronic strain are also common among clinical patients. Some patients may also experience low back pain due to other systemic diseases affecting the lumbar region.
View detailsSciatica
Sciatica is not a specific disease but a symptom, referring to a pain syndrome that occurs along the course of the sciatic nerve due to various causes, specifically pain in the lower back, buttocks, posterior thigh, posterolateral calf, and lateral foot.
View detailsBursitis
A bursa is a small, fluid-filled sac, and there are over 150 of them in the human body. They are located between bones, tendons, joints, and muscles, acting as cushions to prevent friction between these structures. Bursitis is the inflammation of a bursa due caused by friction, traumatic injury, or bacterial infection. It is primarily characterized by localized swelling, pain, and restricted movement.
