iliac spine • Posterior superior iliac spine • Anterior inferior iliac spine • Ischium –Ischial tuberosity –Hamstring or bursa problems –Should sit on this area of pelvis • Pubis –Pubic symphysis • Acetabulum • Femur –Head –Neck –Greater trochanter –Lesser trochanter –Shaft –Medial condyle –Lateral condyle Ligaments - Major source of strength –Ligamentum teres-head of femur –Iliofemoral ligament • Y ligament • Strongest in the body • Prevents hyperextension, external rotation, abduction • Pubofemoral ligament –Prevents abduction • Ischiofemoral ligament –Prevents medial rotation Bursa • 18 in hip • Ischial bursa • Greater trochanteric bursa –Found at attachment of gluteus maximus and IT band • Iliopsoas Muscles • Flexors –Iliopsoas –Rectus femoris (quad) –Sartorius • Anterior thigh (quads)

–Gluteus minimus –Tensor fascia latae (Iliotibial band) • Adductors –Adductor magnus –Adductor brevis –Adductor longus –Pectineus –Gracilis • External Rotators –Oburator externus –Obturator internus –Quadratus femoris –Piriformis – sciatic nerve goes through it. –Gamellus superior –Gamellus inferior –Gluteus maximus • Internal Rotators –Gluteus minimus –Tensor fascia Latae –Gluteus medius Assessment of the Thigh • History –Onset (sudden or slow?) –Previous history? –Mechanism of injury? –Pain description, intensity, quality, duration, type and location? • Observation – Postural symmetry? – Size, deformity, swelling, discoloration? – Skin color and texture? – Is athlete in obvious pain? – Is the athlete willing to move the thigh? • Palpation –Soft tissue of the thigh (anterior, posterior, medial, lateral) should be palpated for pain and tenderness –Bony palpation should also be performed to locate areas of pain/discomfort –Utilize palpation to assess body symmetry • Special Tests –Thomas test • Test for hip contractures –Straight Leg Raise • Test for hip extensor Thomas Test tightness • Can also be used to assess low back or SI joint dysfunction • Trendelenburg Test –Gluteus medius • Ober’s/Noble Test –IT Band • Fulcrum Prevention of Thigh Injuries • Thigh must have maximum strength, endurance, and extensibility to withstand strain • Dynamic stretching programs may aid in muscle preparation for activity • Strengthen programs can also help in preventing injuries Thigh Injuries • Quadriceps Contusions –Cause of Injury • Constantly exposed to traumatic blows –Signs of Injury • Pain, transitory loss of function, immediate bleeding of affected muscles • Early detection and avoidance of internal bleeding are vital – increases recovery rate and prevents muscle scarring Quad Contusion • Care – RICE and NSAID’s – Crutches for more severe cases – Isometric quadriceps contractions should begin as soon as tolerated – Heat, massage and ultrasound to prevent myositis ossificans – Padding may be worn for additional protection upon return to play • Myositis Ossificans Traumatica –Cause of Injury • Formation of ectopic bone following repeated blunt

    Corporate Medical Policy Surgery for Groin Pain in Athletes File Name: surgery_for_groin_pain_in_athletes Origination: 8/2014 Last CAP Review: 6/2020 Next CAP Review: 6/2021 Last Review: 6/2020 Description of Procedure or Service Sports-related groin pain, commonly known as athletic pubalgia or sports hernia, is characterized by disabling activity-dependent lower abdominal and groin pain that is not attributable to any other cause. Athletic pubalgia is most frequently diagnosed in high-performance male athletes, particularly those who participate in sports that involve rapid twisting and turning such as soccer, hockey, and football. Alternative names include Gilmore’s groin, osteitis pubis, pubic inguinal pain syndrome, inguinal disruption, slap shot gut, sportsmen’s groin, footballers groin injury complex, hockey groin syndrome, athletic hernia, sports hernia and core muscle injury. For patients who fail conservative therapy, surgical repair of any defects identified in the muscles, tendons or nerves has been proposed. Groin pain in athletes is a poorly defined condition, for which there is not a consensus regarding the cause and/or treatment. Some believe the groin pain is an occult hernia process, a prehernia condition, or an incipient hernia, with the major abnormality being a defect in the transversalis fascia, which forms the posterior wall of the inguinal canal. Another theory is that injury to soft tissues that attach to or cross the pubic symphysis is the primary abnormality. The most common of these injuries is thought to be at the insertion of the rectus abdominis onto the pubis, with either primary or secondary pain arising from the adductor insertion sites onto the pubis.

  • Sportsmans Groin: the Inguinal Ligament and the Lloyd Technique
    Rennie, WJ and Lloyd, DM. Sportsmans Groin: The Inguinal Ligament and the Lloyd Technique. Journal of the Belgian Society of Radiology. 2017; 101(S2): 16, pp. 1–4. DOI: https://doi.org/10.5334/jbr-btr.1404 OPINION ARTICLE Sportsmans Groin: The Inguinal Ligament and the Lloyd Technique WJ Rennie and DM Lloyd Groin pain is a catch all phrase used to define a common set of symptoms that affect many individuals. It is a common condition affecting sportsmen and women (1, 2) and is often referred to as the sportsman groin (SG). Multiple surgical operations have been developed to treat these symptoms yet no definitive imaging modalities exist to diagnose or predict prognosis. This article aims to discuss the anatomy of the groin, suggest a biomechanical pathophysiology and outline a logical surgical solution to treat the underlying pathology. A systematic clinical and imaging approach with inguinal ligament and pubic specific MRI assessment, can result in accurate selection for intervention. Close correlation with clinical examination and imaging in series is recommended to avoid misinterpretation of chronic changes in athletes.

  • What Are the Differences Between the Skeletons of a Human and a Bird?
    What are the differences between the skeletons of a human and a bird? The avian (bird) skeleton has many features that resemble the human skeleton, and the majority of the bones are the same, they are only shaped different. The arm bones of the human consist of the humerus, the radius and the ulna. These bones are also found in the bird. The leg consists of a long femur which attaches to the pelvis and then two bones of the lower leg. In the bird, these two bones: the tibia and fibula are fused together. The head of both birds and humans is protected by a large cranium. The upper jaw of the human, and the upper beak of the bird is composed of a bone called the maxilla. The lower jaw, and lower beak is composed of a bone called the mandible. The main difference between the human and bird skeleton is that the bird's skeleton is adapted for flight. The bones of a bird are hollow which makes the skeleton lighter. The other differences between the bird and human skeleton are very apparent in the pectoral girdle, which is the place where the forelimbs attach to the spine. The bird's forelimbs are wings and must have a strong support system. The collarbone of the bird is fused to form the furculum, or wishbone. The "shoulderblade" of the human is actually a bone called the scapula, birds have a scapula and they also have an additional shoulder blade bone called the corocoid. Another obvious difference between the human and bird skeleton is the shape and size of the sternum.
