1Muscles that Abduct the Femur at the Acetabulofemoral (Hip) Joint
2Gluteus Medius Gluteus Minimus Tensor Fascia Latae Primary Hip AbductorsGluteus MediusGluteus MinimusTensor Fascia Latae
3Primary Hip Abductors The hip abductors prevent adduction of the hip The hip abductors prevent the pelvis from falling when standing on the same legIf the hip abductors were too weak they would allow the opposite side of the pelvis to drop
4Gluteus MediusOriginExternal surface of Ilium between anterior and posterior gluteal lineInsertionGreater Trochanter of FemurActionAbduction of Femur (entire muscle) (frontal plane and transverse plane)Medially/Internal Rotation of Femur (anterior fibers)Lateral Rotation of Femur (posterior fibers)Depression of Pelvis
5Gluteus Medius Depression of the pelvis is its most important action. When one foot is lifted off the floor (walking and running) The gluteus medius contracts to stabilize the pelvis and prevent sagging on the unsupported limb.When the left muscles are contracted, the right side is prevented from sagging as the right limb is raised during walking.
6Gluteus MediusStand and rock your weight back and forth from one foot to the other while palpating both gluteus musclesThe gluteus medius on the support side (the side that you are bearing your weight on) will be felt as it contracts
7Gluteus Minimus Origin External Surface of Ilium between anterior and inferior gluteal linesInsertionGreater Trochanter of FemurActionAbduction of FemurMedial/Internal Rotation of FemurDepression of Pelvis
8Gluteus Minimus Gluteus minimus is deep to gluteus medius As with gluteus medius, pelvic depression is its most important action
9Gluteus Medius and Minimus Integrated Function:Assists in eccentric deceleration of hip adductionAssists in eccentric deceleration of hip lateral rotationAssists in dynamic stabilization of the lumbo-pelvic hip complex
10Tensor Fascia LataeThe name tells us that this muscle “tenses” the fascia that lies over the muscles of the thighOriginAnterior Superior Iliac Spine and Anterior Part of Iliac CrestInsertionIliotibial Band which attaches to the Lateral Condyle of Tibia
11Tensor Fascia Latae Action Abduction of Femur Medial Rotation of Femur Flexion of FemurAnterior Tilt of PelvisDepression of Pelvis
12Tensor Fascia Latae Integrated Function: Assists in eccentric deceleration of hip adductionAssists in eccentric deceleration of hip extensionAssists in eccentric deceleration of hip lateral rotationAssists in dynamic stabilization of the lumbo-pelvic-hip complex and the tibio-femoral joint
13Tensor Fascia LataeThere are two muscles that attach into the iliotibial band, the tensor fascia latae and gluteus maximusTensor Fascia Latae stabilizes the knee laterally. It prevents collapse of extended knee in ambulation.
14Iliotibial Band Syndrome (ITBS) The main problem occurs when the tensor fasciae latae muscle and iliotibial band become tight.This causes the tendon to pull the knee joint out of alignment and rub against the outside of the knee, which results in inflammation and pain.
15Iliotibial Band Syndrome (ITBS) Is the most common cause of lateral knee pain among athletesIn the US: ITBS is the most common cause of lateral knee pain in runners with some studies citing an incidence as high as 12% of all running-related injuriesDevelops as a result of inflammation of the bursa surrounding the iliotibial band.Generally affects athletes who are involved in sports that require continuous running or repetitive knee flexion and extension such as long-distance running or cycling.May be observed in athletes participating in volleyball, tennis, soccer, skiing, weight lifting, and aerobics.
16Causation of ITBS Overload: Exercising on hard surfaces, like concrete, or uneven groundBeginning an exercise program after a long lay-off periodIncreasing exercise intensity or duration too quicklyExercising in worn out or ill fitting shoesExcessive uphill or downhill runningBiomechanical errors:Leg length differencesTight, stiff muscles in the legMuscle imbalancesFoot structure problems such as flat feetGait, or running style problems such as pronation
17Treatment of ITBS Short Term: Decrease mileage Ice knee after activity. Massage.Alternate running direction on a pitched surfaceLateral sole wedge (orthotics) to lessen pressure on the kneeStretching glutes and TFL MusclesLong Term:Stretching, especially before working out, to make the band more flexible and less susceptible to injury.In extreme cases, surgery to relieve tightness in the band
20Side Plank with Hip Abduction Maintain neutral spineActivate the core by drawing inStart in a side plank positionStraighten the top leg into triple extension (at hip, knee, and ankle).Perform side bridge and HOLD, then move top leg slowly into abduction and adduction.Watch for external rotation in the top leg and for flexion of the hips… if noticed may need more stretching or more cueing
21Standing Abductor Straight Leg Stretch Benefits :Increased function and ROM of the lateral hipPreparation :Stand as pictured with stretching leg crossed in behind.Movement :Laterally flex away from stretching leg until stretch is felt, hold for seconds, repeat 2-3 times.
22Supine Abductor Stretch Straight Leg with Rope Benefits :Increased function and ROM of the hip abductorsPreparation :Position rope/band around the forefoot.Movement :Use rope to adduct leg until stretch is felt, hold for 20-30 seconds, relax and repeat 2-3 reps.
23Assisted Supine Abductor Stretch Straight Leg Benefits :Increased function and ROM of the lateral hip musculature.Movement :Instruct person to actively adduct the leg as far as can be controlled, once at the endpoint, gently assist a few degrees further, hold for sec seconds, relax, and repeat for 2-3 reps.
24Abductor Rollup Lay on your side with a NEUTRAL SPINE. This means hips stacked, shoulders stacked, and something under the head to keep cervical neutral.Maintaining neutral spine, and legs straight, EXTERNALLY ROTATE the entire top leg.Generate ALL motion from the HIP allowing no compensation/movement anywhere else in the body.Hold at end range briefly, return to starting position and repeat.1 set of 5-10 reps.
