Bio-mechanics of the hip joint
The document discusses the biomechanics of the hip joint, including its structure, motions, stability mechanisms, and common injuries. The hip is a ball-and-socket joint between the pelvis and femur that allows for flexion/extension, abduction/adduction, and internal/external rotation. Stability is provided by bony configuration, cartilage, ligaments like the iliofemoral and ischiofemoral, and large muscles like the gluteals. Common injuries include fractures from direct impacts or degenerative joint disease from repeated stresses.
Biomechanics of knee
The document provides an overview of the biomechanics of the knee joint. It discusses the tibiofemoral and patellofemoral joints, including the articulating surfaces, menisci, ligaments, muscles, and movements. It describes problems that can occur in each joint like meniscus injuries, ACL tears, patella alta, and condromalacia patellae. Key concepts covered are the screw home mechanism of knee locking in extension, the Q-angle of the patella, and how joint reaction forces increase with flexion angle during stance and swing phases of gait.
Knee biomechanics
The knee is a complex joint composed of the tibiofemoral and patellofemoral joints. It functions to provide mobility and support body weight during both static and dynamic activities. The knee joint contains menisci that increase joint congruence and distribute weight forces. It also contains cruciate and collateral ligaments that restrict motion and provide stability. During flexion and extension, the tibia glides and rotates on the femur through rolling and sliding motions controlled by the ligaments and menisci.

Biomechanics of Lumbar spine
The lumbar region consists of vertebrae adapted to support great compressive loads from the upper body. Lumbar vertebrae have massive wedge-shaped bodies and processes for muscle attachment. Intervertebral discs are the largest in the body and concave posteriorly to resist bending forces. The L5 vertebra articulates with the sacrum at the lumbosacral joint. Strong ligaments including the iliolumbar ligament stabilize the region. The lumbar spine functions through flexion, extension, and lateral movements while transmitting weight and resisting shear forces with compression distributed between interbody and facet joints.
BIOMECHANICS OF HIP JOINT BY Dr. VIKRAM
The hip joint is a ball-and-socket joint that allows flexion, extension, abduction, adduction, and rotation. It is formed by the acetabulum of the pelvis articulating with the femoral head. The primary function is to support the weight of the upper body. Key biomechanical aspects include the angles of inclination and torsion of the femur, congruence of the joint surfaces, and forces transmitted during weight bearing that are balanced by the joint capsule and trabecular bone structure. Motion occurs through tilting and rotation of the pelvis on a fixed femur. Surrounding muscles provide dynamic stability and control movement.
Biomechanics of HIP
This document summarizes the biomechanics of the hip joint. It describes the bony anatomy including the femoral head, acetabulum, and labrum. It also discusses the capsule, ligaments including the iliofemoral, pubofemoral, and ischiofemoral ligaments. Muscles that act on the hip joint and the ranges of motion are outlined. Factors affecting hip joint stability and weight transmission through the joint are summarized. Pathomechanics related to variations in the neck shaft angle and angle of torsion are covered.
Hip joint biomecanics
The hip joint connects the femur to the pelvis and supports the weight of the upper body. It has a ball and socket structure, with the femoral head forming the ball and the acetabulum forming the socket. Several ligaments stabilize the hip joint, including the iliofemoral ligament which resembles an inverted Y shape. The hip joint allows flexion, extension, abduction, adduction, and rotation. Femoroacetabular impingement can occur if the femoral head or acetabulum have abnormal shapes that cause them to impinge upon each other.
BIOMECHANICS OF ELBOW COMPLEX
The elbow complex is designed to provide mobility and stability for the hand. It consists of three joints - the humeroulnar joint between the humerus and ulna, the humeroradial joint between the humerus and radius, and the superior and inferior radioulnar joints. These joints allow for flexion-extension, pronation, and supination movements. The elbow is stabilized by ligaments and muscles like the biceps brachi, triceps, and pronators. Common problems affecting the elbow include tennis elbow, golfer's elbow, nursemaid's elbow, and cubital tunnel syndrome.

Pelvic tilt
The document discusses pelvic tilt, which is an anteroposterior motion of the pelvis around an imaginary axis in the frontal plane. There are three main types of pelvic tilt: anterior, posterior, and lateral. Anterior pelvic tilt involves the ASIS moving anteroinferiorly, dropping the front of the pelvis and raising the back. Posterior pelvic tilt is the opposite, with the ASIS moving posteriorly, raising the front of the pelvis and dropping the back. Lateral pelvic tilt describes tilting to either side and can occur with conditions like scoliosis. The document also discusses measuring the angle of pelvic tilt and using exercises to improve postural control of the pel

Biomechanics of hip complex 3
This document discusses forces on the hip joint during bilateral and unilateral stance. In bilateral stance, each hip experiences approximately one-third of body weight compression from gravity. Additional compression may come from hip muscles. In unilateral stance, the supporting hip experiences compression of approximately five-sixths of body weight from gravity. Additional compression comes from hip abductor muscle contraction needed to counter the adduction torque from the weight of the body. Together these forces can result in a total hip joint compression of around 2-3 times body weight in unilateral stance.
Joint lubrication by dr debasis mukherjee
The document discusses lubrication of synovial joints. It states that synovial fluid and articular cartilage are much slipperier than ice or lubricated metals. It then describes the various lubrication processes for articular cartilage - boundary lubrication, fluid-film lubrication, hydrodynamic lubrication, and squeeze-film lubrication. Boundary lubrication occurs with an adsorbed layer preventing surface contact while the others involve fluid films. The lubrication type depends on factors like loading and movement. Mixed lubrication involving different areas is common. Elastohydrodynamic lubrication also occurs as cartilage deforms under pressure. In summary, the key lubrication modes work together dynamically based on joint loading and motion.
Hip biomechanics
This document discusses the biomechanics of the hip joint. It begins by defining biomechanics and describing the mobility and stability of the hip. It then discusses forces acting on the hip like body weight, abductor muscles, and joint reaction forces. It explains how these forces are balanced in different positions like two-leg stance, single-leg stance, and with the use of a cane. The document concludes by discussing implications for conditions like coxa valga and coxa vara, and principles of total hip replacement surgery.
Pelvic tilt
This document defines and describes different types of pelvic tilts, including anterior, posterior, lateral, and rotational tilts. Anterior and posterior tilts occur in the sagittal plane and can be measured using the lumbosacral angle or pelvic inclinometer. Anterior tilt is caused by hip flexor and spinal extensor contraction, while posterior tilt is caused by hip extensor and spinal flexor contraction. Lateral tilts and drops occur in the frontal plane, with examples being hip hiking caused by contralateral muscles and pelvic dropping caused by weak hip abductors. Pelvic rotation occurs in the transverse plane during walking.
Biomechanics of hip complex 4
This document discusses strategies to reduce force on the hip joint for individuals with hip osteoarthritis or weak hip abductor muscles. It analyzes using a lateral lean, cane on the same side, or cane on the opposite side. A lateral lean reduces gravitational torque but increases energy expenditure. A cane on the same side provides some relief but a cane on the opposite side may offset gravity's torque, reducing the need for abductor muscle force and joint compression to just body weight. However, the full distance between hand and hip may overestimate the cane's effectiveness.

Biomechanics of shoulder
The shoulder complex is composed of four joints that link the upper extremity to the thorax. It includes the sternoclavicular joint, acromioclavicular joint, scapulothoracic joint, and glenohumeral joint. The shoulder complex provides a large range of motion but has more laxity than other joints, making it prone to instability and injury without the dynamic stabilization of muscles and ligaments. The glenohumeral joint in particular is a ball-and-socket synovial joint surrounded by a large capsule that relies on reinforcement from ligaments and the rotator cuff muscles.
Bones of upper limbs & amp; radiographic terminology
The human skeleton consists of around 300 bones at birth that decreases to 206 bones in adults. The skeleton can be divided into the axial skeleton, which includes the bones of the skull and thorax, and the appendicular skeleton, which includes the bones of the upper and lower limbs and connects to the axial skeleton via girdles. The appendicular skeleton consists of long bones in the upper and lower limbs that allow for movement, as well as short bones in the hands, wrists, feet, and ankles. The document further describes the bones and movements of the upper limb.
Shoulder anatomy
The shoulder joint is comprised of three bones and three joints: the scapula, clavicle, and humerus. It allows for flexion, extension, abduction, adduction, external rotation, and internal rotation. Stability is provided by ligaments like the glenohumeral ligament and muscles like the rotator cuff. Common injuries include dislocations, rotator cuff tears, and tendonitis which can cause pain and limited mobility.
Elbow dislocation
1) Elbow dislocations are most commonly posterior dislocations, which occur due to a combination of hyperextension, valgus stress, arm abduction, and forearm supination.
2) Treatment depends on whether the dislocation is simple or complex, with associated fractures or ligament injuries requiring operative management like open reduction and repair of soft tissues.
3) The terrible triad of elbow injuries involves a dislocation with fractures of the radial head and coronoid process, requiring restoration of stability through fixation of the fractures and repair of collateral ligaments.

The document summarizes the biomechanics of the ankle joint complex. It describes the anatomy and function of the talocrural joint (ankle joint), subtalar joint, and transverse tarsal joint. The ankle-foot complex consists of 28 bones and 25 joints that allow the foot to meet stability and mobility demands through dorsiflexion, plantarflexion, pronation, and supination movements. Key bones include the talus, tibia, and fibula. Ligaments such as the deltoid and tibiofibular ligaments provide stability to the ankle mortise.
Applied Biomechanics of Cervical Spine
The document provides information on the biomechanics of the cervical spine. It discusses the vertebrae, ligaments, joints, motions, forces, and muscles involved. Key points include that the atlantoaxial joint allows rotation, the atlantooccipital joint allows flexion and extension, and lateral flexion is coupled with rotation. Degenerative changes from aging can cause conditions like cervical spondylosis or radiculopathy by reducing the disc space and increasing pressure on nerves. Maintaining healthy discs is important for protecting spinal structures.
Shoulder biomechanics- Acromioclavicular joint

Sectional dentures for microstomia patients.pptx
Microstomia, characterized by an abnormally small oral aperture, presents significant challenges in prosthodontic treatment, including limited access for examination, difficulties in impression making, and challenges with prosthesis insertion and removal. To manage these issues, customized impression techniques using sectional trays and elastomeric materials are employed. Prostheses may be designed in segments or with flexible materials to facilitate handling. Minimally invasive procedures and the use of digital technologies can enhance patient comfort. Education and training for patients on prosthesis care and maintenance are crucial for compliance. Regular follow-up and a multidisciplinary approach, involving collaboration with other specialists, ensure comprehensive care and improved quality of life for microstomia patients.
