Dupuytren's disease is characterized by fibrotic nodules and bands in the palmar aponeurosis, leading to flexion deformities in the fingers. The etiology is unclear, with higher incidence in Europe. Clinical presentation varies, with treatment options including collagenase injections, needle aponeur

Knee is the largest joint of the human body, it is a hinge joint which allows flexion and extension and also slight internal and external rotation. It connects our thigh to our lower leg. Similar to all other joints, the knees are part of our skeletal system. The knee helps to support our weight. It

Understanding pathological gait variations related to hip joint differences is crucial in gait analysis. Excessive sagittal, coronal, and transverse plane motions impact stance and swing phases, leading to deviations in gait patterns. Excess flexion, limited flexion, past retraction, excess adductio

Joint motion involves osteokinematic movements, which are under voluntary control and include flexion, extension, and more. End-feel sensations like bony, capsular, and springy block indicate different joint conditions. Arthrokinematic motion refers to how joint surfaces move during osteokinematic m
