Hip Joint
The hip joint forms the connection between the lower limb and the pelvic girdle

Blood Supply of the Hip Joint The medial and
lateral circumflex femoral arteries
The artery to the head of the femur
![Page 10: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/10.jpg)
Avascular Necrosis of head
More common >60 years
In female for osteoporosis
Supplied mainly by Medial circumflex femoral artery by its retinacular branches
Blood supplied through round ligament of femur(br. Of Obturator) is grossly inadequate.

bursitis is caused by friction between the skin and the patella.
This condition has been called housemaid's knee.

MOVEMENTS of the Ankle Joint 1. Dorsiflexion of the ankle 2. Plantarflexion of the ankle
The movements of inversion and eversion take place at the tarsal joints and not at the ankle joint.

Clinical Anatomy
![Page 40: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/40.jpg)
Pott fracture(dislocation of the ankle) Occurs when the foot
is forcibly everted. Trimalleolar fracture: The combined
fracture of the medial malleolus, lateral malleolus, and the posterior margin of the distal end of the tibia is known as a "trimalleolar fracture
![Page 41: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/41.jpg)
Arches of the Foot
The bones of the foot do not lie in a horizontal plane. Instead, they form longitudinal and transverse arches relative to the ground.
The arches distribute weight over the pedal platform (foot), acting not only as shock absorbers but also as springboards for propelling it during walking, running, and jumping.
![Page 42: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/42.jpg)
Longitudinal arch
The longitudinal arch of the foot is formed between the posterior end of the calcaneus and the heads of the metatarsals.
It is highest on the medial side where it forms the medial part of the longitudinal arch and lowest on the lateral side where it forms the lateral part.
![Page 43: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/43.jpg)
Arches of the foot.

Transverse arch
The transverse arch of the foot runs from side to side
It is formed by the cuboid, cuneiforms, and bases of the metatarsals. The medial and lateral parts of the longitudinal arch serve as pillars for the transverse arch.
![Page 46: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/46.jpg)

Major Ligaments of the Foot 1. Plantar calcaneonavicular ligament
(spring ligament): The spring ligament supports the head of the talus and plays important roles in the transfer of weight from the talus and in maintaining the longitudinal arch of the foot, of which it is the keystone (superior most element).
2. Long plantar ligament 3. Plantar calcaneocuboid ligament
(short plantar ligament).
![Page 49: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/49.jpg)
Support for arches of the foot
![Page 50: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/50.jpg)
Clinical Anatomy
1.Hallux Valgus: Hallux valgus is a
foot deformity caused by pressure from footwear and degenerative joint disease; it is characterized by lateral deviation of the great toe
![Page 51: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/51.jpg)
Flatfeet
Flatfeet can either be flexible (flat, lacking a medial arch, when weight bearing but normal in appearance when not bearing weight ) or rigid (flat even when not bearing weight).
![Page 52: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/52.jpg)
The Q- angleThe femur is diagonally placed within the
thigh, whereas the tibia is almost vertical within the leg, creating an angle at the knee between the long axes of the bones.
The angle formed between the two bones is called the Q- angle.
The Q- angle is assessed by drawing a line from the ASIS to the middle of the patella and extrapolating a second line passing through the middle of patella and tibial tuberosity.
It is wider in females than males.
![Page 53: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/53.jpg)
The Q-angle
![Page 54: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/54.jpg)
Genu varum
When the leg is medially angulated in relation to the thigh, the femur becomes abnormally vertical, making the Q- angle small.
The line of weight bearing falls medial to the center of the knee, excess pressure is placed on the medial aspect of the knee and the Medial meniscus becomes destroyed.
The fibular collateral ligament ( lateral Collateral ligament) is overstressed.
![Page 55: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/55.jpg)
Genu varum
It is also called bow-leggedness); a physical deformity marked by (outward bowing) of the leg in relation to the thigh, giving the appearance of an archer's bow.
![Page 56: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/56.jpg)
Genu Varum and Genu Valgum
![Page 57: HIP JOINT, KNEE JOINT and ANKLE JOINT Type Articulation Capsule Ligaments Movements](https://reader036.vdocument.in/reader036/viewer/2022062321/56649e0b5503460f94af3d9b/html5/thumbnails/57.jpg)
Genu Valgum
When the leg is laterally angulated in relation to the thigh, Genu Valgum results ( Knock- knee).
The weight- bearing line falls lateral to the center of the knee.
The Tibial collateral ligament ( Medial Collateral Ligament) subsequently becomes over stretched , lateral meniscus becomes overstressed.

Genu valgum
It is commonly called "knock-knees", is a condition where the knees touch one another when the legs are straightened.
