Origin: (proximal attachments) a.Anterior surface of lateral sacrum. TheÂ proximalÂ femoral head articulates with the acetabulum of the pelvis, forming a “ball-and-socket” joint. The muscles that form the quadriceps femoris unite proximal to the knee and attach to the patella via the quadriceps tendon. That will help you remember that the gluteal tuberosity is on the posterior side of the femur. The shaft is almost a cylindrical structure wide superiorly and inferiorly and narrowest in the middle. Vastus intermedius muscle arises from front and lateral surface of the femur. Femur: The femur is classed as a long bone, only bone in the thigh, and the longest bone in the body. Muscle Attachments. Case Discussion. It is composed of an upper end, a lower end and a shaft. The lateral surface is crossed by an oblique ridge directed downwards and forwards. Some biarticular muscles â which cross two joints, like the gastrocnemius and plantaris muscles â also originate from the femur. The gluteus medius and minimus, gemellus superior and inferior, obturator internus, and piriformis are some muscles that insert on the greater trochanter. Adductor magnus is inserted into the medial margin of the gluteal tuberosity, the linea aspera, the medial supracondylar line, and the adductor tubercle.

The apex is the inturned posterior part of the posterior border. ligaments. A femoral stress fracture is a situation described by an incomplete crack in the femur. It contains two facets for attachment of internal knee ligaments. The Origin And Insertion Of Muscles Corewalking Hello, What's up guys? The two condyles are partially covered by a large articular surface. Distally, theÂ femoral condylesÂ of the femur articulate with the condyles of the tibia, making the tibiofemoral joint. The shaft possesses 3 surfaces as well – anterior, medial and lateral. It marks the junction of the posterior surface of the neck with the shaft of the femur. The three vasti attach to the top of the femur. Medial and lateral intermuscular septa are attached to the lips of the linea aspera and to the supracondylar line. It is convex forwards and is directed obliquely downwards and medially. The anterior surface is rough in its lateral part. Quadratus femoris muscle Insert into the intertrochanteric crest of the femur. The distal fragment is pulled upwards and rotated laterally. Muscles which arise from the femur will cross the knee joint to insert on the proximal tibia â¦ The upper border, concave and horizontal, meets the shaft at the greater trochanter. The gastrocnemius, one of the calf muscles, attaches here, as do all of the glute muscles. The anterior surface of the femoral neck is entirely intracapsular.

The iliopsoas muscle inserts on the lesser trochanter. So, watch this fun lecture and maximize your learning! Posteriorly, they are separated by a deep gap, termed the intercondylar fossa or intercondylar notch, and project backwards much beyond the plane of the popliteal surface. Its length varies from one-fourth to one-third of that of the body; The main function of the femur is to transmit forces from the tibia to the hip joint. It is not intracapsular in its lower lateral part. Muscles that originate from the pelvis and insert on the anterior or posterior surface of the femur to facilitate flexion and extension around the hips. Adductor brevis is inserted into a line extending from the lesser trochanter to the upper part of the linea aspera, behind the pectineus and the upper part of the adductor longus. The intercondylar line provides attachment to the capsular ligament and laterally to the oblique popliteal ligament. The upper border of the trochanter lies at the level of the center of the head. All of the hip flexor muscles attach from the pelvis or spine to the femur or tibia, which is how they influence hip flexion. The nutrient foramen (or foramina) is located on the medial side on the linea aspera and is directed upwards. Gross anatomy It is composed of the upper extremity, body and lower extremity and provides several muscular origins and insertions. Thus a cold abscess is not accompanied by the classical […], Congenital pseudarthrosis of tibia is an uncommon disease with clinical presentations ranging from simple anterolateral tibial angulation to complete non-union with extensive bone defects. Anteversion is the angle formed between the transverse axis of the upper and lower ends of the femur. The rounded elevation, a little above its middle is called the quadrate tubercle. The femur is the only bone in the thigh and the longest bone in the body. The upper end of the femur includes the head, the neck, the greater trochanter, the lesser trochanter, the intertrochanteric line, and the intertrochanteric crest.

Obturator externus muscle Insert into the trochanteric fossa. After epiphyseal fusion, the lateral epiphyseal arteries anastomose freely with the metaphyseal arteries. The â¦ The neck is about is about 3-3.5 cms long and connects head with the shaft. The femur (plural: femora) is the longest, most voluminous and strongest bone in the human body. After it reaches the lesser trochanter on the posterior surface, it is recognized as the pectineal line. It can be divided into three areas; proximal end, shaft and the distal end. When the knee is flexed, the tendon of this muscle lies in the shallow posterior part of the grove. It has a glossy surface with a depression on the medial position; for the attachment of the ligament of head of the femur. These arterial twigs enter the acetabular notch and then pass along the round ligament to reach the head. The head is directed medially. As the name suggests, it allows for the attachment of the gluteus maximus, which is your butt muscle. Its superior surface bears a circular articular facet directed upward, forward, and medialward, for articulation with a corresponding surface on the lateral condyle of the tibia.On the lateral side is a thick and rough prominence continued behind into a pointed eminence, the apâ¦ Greater trochanterÂ âÂ A projection of bone that starts from the anterior aspect, just parallel to the neck. Gluteus maximus muscle Insert into the gluteal tuberosity. The five flexor tendon zones apply only to the index through small fingers as separate zones exist for the thumb flexor tendon. It teams up with tibia and bones of the foot to help you fight against gravity, enabling you to stand and perform movements of your lower limb. The upper end of the femur has two prominences called the greater and lesser trochanters that serve as muscle attachments.

The femur is also called the thigh bone and is the longest and strongest bone of the body. There are also two bony ridges connecting the two trochanters. The Proximal end consists of a head, neck, and two trochanters. Anteriorly, the condyles articulate with patella and this articulation extends more on the lateral condyle than on the medial. The primary centre appears in the midshaft. They are the area of attachment of some muscles and the collateral ligaments of the knee joint. Biceps Femoris: A similar muscle to the biceps brachii in the upper arm, also double-headed. The extracapsular part of the neck is supplied by the ascending branch of the medial circumflex femoral artery. It has two large condyles – medial and lateral. Start studying Muscle Attachments of the Hip and Thigh. Plantaris muscle arises from over the lateral condyle of the femur. In the adult it is about 1 cm lower than the head. Secondary centres. The lateral condyle is flat laterally, less prominent than medial condyle and stouter than it. In all, 23 individual muscles either originate from or insert onto the femur. The neck has two borders and two surfaces. Anterior cruciate ligament – posterior part of the medial surface of the lateral condyle. The primary center for the shaft appears in the 7 weeks of intrauterine life. The angle facilitates movements of the hip joint. As mentioned above, the psoas major muscle starts from the lower vertebral column and then travels down through the pelvis and attaches to the femur. What muscle is attached to bones? HeadÂ âÂ Connects with the acetabulum of the pelvis to make the hip joint. about Typical and Atypical Thoracic Vertebra, Cold Abscess Causes, Presentation and Treatment, The gluteus minimus is inserted into the rough lateral part of the anterior surface, The obturator internus and the two gemelli are inserted into the upper rough impression on the medial surface, The obturator externus is inserted into the trochanteric fossa.

Muscle attachments of the lower end â Gastrocnemius: The medial head originates from the popliteal surface just above the medial condyle. As the femur is the only bone in the thigh, it serves as an attachment point for all the muscles that exert their force over the hip and knee joints. Linea aspera is an important landmark in orthopedics surgeries involving reduction of femoral fractures. Articularis genu – just below the vastus intermedius. Two faint grooves separate the patellar articulation surface from tibial surfaces. Piriformis muscle Insert into the superior boundary of the greater trochanter. The greater trochanter is located at the junction between the neck and the shaft of the femur bone. These septae separate the extensor muscles from the adductor medially, and from the flexors laterally. Arun Pal Singh is an orthopedic and trauma surgeon, founder and chief editor of this website. The upper apophyses (lesser trochanter, greater trochanter and head, in that order) fuse with the shaft at about 18 years. The muscular impression near the lateral epicondyle gives origin to the lateral head of the gastrocnemius. Vastus intermedius – upper three-fourths of the anterior and lateral surfaces. The lower epiphysis fuses by the 20th year. Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female. Iliacus muscle Insert into the lesser trochanter of the femur. Knee bursas or bursae are of two types. The lower border, straight and oblique, meets the shaft near the lesser trochanter. Iliacus muscle Insert into the lesser trochanter of the femur. This brings the knees closer to the bodyâs center of gravity, increasing stability. The epiphyseal line for the lower end of the femur passes through it. Scaled femoral muscle attachment centroids Femoral muscle attachments (mm) Mean This study SD Brand et al. All of the femoral ossification centresÂ fuseÂ between the ages of 14 and 18 years. A lot of the large thigh muscles arise from and insert on the various parts of the femur. The trochanteric bursa of the gluteus medius lies in front of the ridge, and the trochanteric bursa of the gluteus maximus lies behind the ridge. On the posterior surface of the femoral shaft, a roughened ridges of bone, these are also described as the linea aspera. Pectineus: The pectineus muscle is a large flat muscle found in the thigh. From the case: Femur - muscle attachments (Gray's illustration) Diagram. Facet for attachment of the posterior cruciate ligamentÂ âÂ Found on the medial wall of the intercondylar fossa, it is a large rounded flat face, where the posterior cruciate ligament of the knee attaches. It is a clinical label for the patient’s condition with many differentials in the offering. There is a rounded tubercle on its superior half, this is designated the quadrate tubercle, where the quadratus femoris attaches. Articular cartilage covers the ends of bones. Gluteus minimus muscle Insert into the forefront of the greater trochanter. Greater Trochanter. Gluteus medius muscle Insert into the lateral surface of the greater trochanter of the femur. Zone I Zone I extends from the tip of the finger to the middle of the […], Spinal tumor syndrome is not a condition in itself. The upper and bears a rounded head, whereas the lower end is widely expanded to from two large condyles. Three of the four quadriceps muscles attach to various points on the femur as well. It is a rare disease, with an estimated frequency of 1/150,000 births. The distal end is marked by the presence ofÂ the medial and lateral condyles, which join with the tibia and patella, forming the knee joint. In turn, the patella is attached to the tibia by the patella ligament. Movement at the tibiofemoral joint happens in two planes: internal and external rotation in the horizontal plane, knee flexion, and extension in the sagittal plane. It marks the junction of the neck with the femur. The cylindrical shaft is convex forwards. When the surface of the cartilage is […], Parsonage Turner syndrome or brachial neuritis is a rare disorder which affects lower motor neurons of brachial plexus and/or nerves and their branches and is manifested by acute shoulder pain followed by weakness of the muscles of the shoulder. It is angled superiorly and posteriorly and can be found on both the anterior and posterior sides of the femur. It is a traction â¦ This set constitutes the main supply and damage to it results in necrosis of the head of the following fractures of the neck of the femur. If the lesion is all the way through the cartilage, it is called full-thickness lesion, otherwise, it is a partial thickness lesion. Through flexion and extension of theÂ knee joint, the articular surfaces of the patella and femur offer a sliding movement. Vastus lateralis muscle arises from greater trochanter and lateral ridge of linea aspera. Proximally, the medial border of the linea aspera fits the pectineal line. The femur is an integral component of ambulation. Thus this part of the shaft has four borders (medial, lateral, supracondylar line and lateral supracondylar line) 4 surfaces (anterior, medial, lateral and popliteal). It is the site of several muscle attachments. Those […], There are five flexor tendon zones in hand. Vastus medialis muscle arises from the distal part of an intertrochanteric line and medial ridge of linea aspera of the femur. ( 135 degrees), Coxa vara is a condition where the neck-shaft angle is less than normal (120 degrees). The Linea aspera has distinct medial and lateral lips. TheÂ patellofemoralÂ joint is made by the articulation of the patella with the intercondylar groove of the femur. This formation allows for three planes movement at the hip joint: abduction and adduction in the frontal plane, flexion, and extension in the sagittal plane and internal and external rotation in the horizontal plane. It is capable of leaving residual disability in 10-20% patients. The lesser trochanter is also called the minor trochanter, the inner trochanter, and the medial process of the femur. Distally, the linea aspera increases and forms the floor of the popliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines. Similarly, the two lips of the Linea aspera diverge in lower one third and enclose an additional, popliteal surface. Flexor tendon zones influence prognosis following flexor tendon repair. The prefix cold indicates that the abscess is not hot because that is the usual case. In this article, we shall look at the anatomy of the femur â its attachments, bony landmarks, and clinical correlations. The smaller, medial part of the head, near the fovea, is supplied by medial epiphyseal arteries derived from the posterior division of the obturator artery and from the ascending branch of the medial circumflex femoral artery. Patellofemoral pain syndrome is a well-known sports-related injury that manifests as pain around or behind the patella. Tibial collateral ligament of the knee – medial epicondyle, Hamstring part of the adductor magnus – adductor tubercle. 3. The infrapatellar synovial fold is attached to the anterior border of the intercondylar fossa. Vastus medialis – Lower part of the intertrochanteric line, the spiral line, the medial lip of the linea aspera, and the upper one –fourth of the medial supracondylar line. To understand spinal tumor syndrome one must first know about the typical presentation […], Articular cartilage injury is common and the lesions appear as tears or potholes in the surface of the cartilage. It is a smooth rounded ridge which begins above at the posterior superior angle of the greater trochanter and ends at the lesser trochanter. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. *.
