This document discusses several causes of intoeing, including femoral anteversion, internal tibial torsion, metatarsus adductus, and congenital talipes equinovarus (CTEV). It compares normal foot positioning to conditions like metatarsus adductus and CTEV that can cause the foot to turn inward. Additionally, it examines how increased femoral anteversion can cause the greater trochanter to move posteriorly, requiring intoeing to compensate, and how internal tibial torsion works to counteract femoral anteversion by allowing increased internal hip rotation.
Anatomy of The hip joint & femoral Head
The hip joint is a ball and socket joint between the femoral head and acetabulum. It provides stability for weight bearing while allowing some mobility. The acetabulum cups the femoral head, and various ligaments like the iliofemoral ligament stabilize the joint. The femoral head has an epiphyseal blood supply from lateral and medial vessels, while the neck and shaft receive blood from an extracapsular arterial ring. The hip joint allows flexion, extension, abduction, adduction, and rotation.
Anatomy of the foot
The document provides details on the anatomy of the foot, including:
- The sensory nerve supply to the skin of the dorsum comes from the superficial peroneal, deep peroneal, saphenous, and sural nerves.
- The dorsalis pedis artery originates from the anterior tibial artery and runs along the dorsum of the foot, giving off branches.
- The sole of the foot contains 4 layers of muscles and its skin has sensory innervation from the medial and lateral plantar nerves.
- The medial and lateral plantar arteries originate from the posterior tibial artery and supply structures in the sole.
Anterior compartment of thigh copy
The anterior compartment of the thigh is divided into three sections by intermuscular septa. It contains the sartorius muscle and quadriceps femoris muscles which act to flex and extend the leg. The femoral artery and nerve pass through the femoral triangle and adductor canal, branching to supply the thigh muscles. The deep fascia of the thigh forms the iliotibial band and encloses the femoral sheath around the vessels in the upper thigh.
Habitual dislocation patella
The document summarizes the surgical treatment of congenital and habitual dislocation of the patella. These conditions are caused by contracture of the quadriceps mechanism, which is more severe in congenital dislocation. The surgical treatment involves an extensive lateral release, medial plication to realign the patella, and transfer or lengthening of surrounding tendons like the semitendinosus and rectus femoris tendons to further optimize quadriceps alignment and prevent recurrent dislocation. The case study describes the successful surgical stabilization of a 10-year old girl's bilaterally habitually dislocating patellas using various soft tissue procedures like lateral release, medial plication, and advancement of the vastus medialis

Knee locking & Unlocking
"Knee locking" is quite literally when your knee locks up momentarily, inhibiting your ability to move in any direction. This can also be described as "catching" where it feels as if your knee gets caught during extension or flexion, the knee
"giving out," or as a popping sensation with knee movement. Unfortunately, there is no "key" or secret trick to unlock your knee joint, though various treatments exist to help with knee locking symptoms.
Ankle joint and joints of foot
The document provides details about the ankle joint and joints of the foot. It discusses the tibiofibular articulation including the superior, interosseous, and inferior tibiofibular joints. It then describes the ankle (talocrural) joint, including its range of motion, articulating surfaces, joint capsule, ligaments, synovial membrane, vascular supply, innervation, and factors maintaining stability. Finally, it summarizes the small joints of the foot including the talocalcaneal, talocalcaneonavicular, calcaneocuboid, naviculocuneiform, and intercuneiform joints.
Anatomy of ankle joint
The ankle is a complex joint made up of the ankle joint proper, subtalar joint, and inferior tibiofibular joint. The ankle joint itself involves the tibia and fibula meeting with the talus bone. It allows for dorsiflexion and plantar flexion. The subtalar joint connects the talus to the calcaneus bone and permits side to side foot motion. Strong ligaments including the deltoid and lateral ligaments provide stability to the ankle joints. The talus bone transmits body weight and articulates with the tibia, fibula, navicular, and calcaneus. Blood supply comes from surrounding arteries and the ankle joints are innervated by nearby nerves.
Complete knee joint anatomy
The knee joint is composed of three joints: the medial and lateral tibiofemoral joints and the patellofemoral joint. It is supported by numerous ligaments including the anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, menisci, and synovial membrane. The patella glides within the femoral groove during knee flexion and extension to enhance the leverage of the quadriceps muscle. The medial and lateral menisci act as shock absorbers between the femur and tibia.
Hip joint anatomy
The hip joint is a ball and socket synovial joint that allows flexion, extension, abduction, adduction, and rotation. It has a high degree of stability provided by the depth of the acetabulum, strong ligaments like the iliofemoral ligament, and surrounding muscles. The femoral head articulates with the acetabulum and is supported by ligaments including the fibrous capsule, acetabular labrum, and transverse acetabular ligament. Flexion is produced by the psoas major and iliacus while abduction is performed by the gluteus medius and minimus.
Habitual dislocation of patella
This case report describes a 21-year old female patient with a 10-year history of habitual left patellar dislocation. Examination found lateral subluxation of the patella in flexion and reduced range of motion. X-rays showed patella baja on the left side and lateral dislocation of the patella. The patient underwent a proximal and distal soft tissue realignment procedure involving lateral release, medial reinforcement, and partial medialization of the patellar tendon. Post-operatively, the patella was centrally located with improved range of motion and stability. Habitual patellar dislocation is rare in adults and can be treated with soft tissue realignment surgery to reinforce the medial structures and release tight

The gluteal region is located between the trunk and lower extremity. It includes the buttocks and hip region. The gluteal region contains important muscles like the gluteus maximus, medius, and minimus. It is innervated by the superior and inferior gluteal nerves. The piriformis muscle passes through the greater sciatic foramen. Other muscles in the region include the obturator internus, quadratus femoris, and hamstring muscles. Major blood vessels and nerves like the sciatic nerve also pass through the gluteal region.
Muscles of thigh
The document describes the muscles of the thigh and gluteal region. It discusses:
1. The thigh region is divided into four compartments - anterior, medial, posterior, and lateral. The anterior compartment contains muscles that flex the hip and extend the knee. The medial compartment contains adductor muscles. The posterior compartment contains hamstring muscles that extend the hip and flex the knee.
2. The gluteal region contains the gluteal muscles - gluteus maximus, medius, and minimus. It also contains smaller lateral rotator muscles.
3. Several important structures pass through openings in the pelvis. The sciatic nerve passes through the greater and lesser sciatic foramina.
hipjointanatomy
The hip joint is a ball-and-socket joint between the femur and acetabulum. It is made up of bones, cartilage, ligaments, synovial membrane, muscles and nerves. The acetabulum forms the socket of the joint and is reinforced by the acetabular labrum. The femoral head forms the ball and articulates with the acetabulum. Strong ligaments including the iliofemoral, ischiofemoral and pubofemoral ligaments reinforce the joint capsule. The hip joint is supplied by branches of the femoral, sciatic and obturator nerves and has an extensive blood supply. Bursae around the hip joint help with movement.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.TEST BANK For An Introduction to Brain and Behavior, 7th Edition by Bryan Kol...
