Q

Extracapsular ligaments that reinforce the hip joint

A
  • iliofemoral ligament
    -pubofemoral ligament
    -ischiofemoral ligament
17
Q

The ligaments that convert the geater and lesser sciatic notches into foramina

A
  • sarcospinous ligament
  • sacrotuberous ligament
18
Q

The sacrotuberous ligament

A
  • fan shaped
  • extends from the PSIS/ dorsolateral sacrum & coccyx to the ischial tuberosity
19
Q

The sacrospinous ligament

A
  • smaller
  • attached from the ischial spine to the lateral sacrum & coccyx
20
Q

Fascia Lata

A

deep fascia of the thigh

21
Q

Crural Fascia

A

deep fascia of the leg

22
The fascia lata is thick laterally forming the
Iliotibial tract
23
Common cause of lateral knee pain
iliotibial tract (band) syndrome (ITBS) - friction of the IT tract against the lateral epicondyle of the femur with flexion/extension
24
Sacral Plexus
L4-S4, innervates the gluteal region and entire lower limb
25
Femoral and Obturator nerves arise from
the lumbar plexus (L2-L4)
26
The lumbosacral plexus nerves exit through
the greater sciatic foramen
27
Gluteus Maximum OIAI
O: thoracolumbar fascia, gluteal fossa of the iliac wing, sacrotuberous ligament, posterior/inferior sacrum & coccyx I: gluteal tuberosity of the femur, ITB A: external rotation, extension, abduction of the thigh at the hip I: inferior gluteal nerve
28
Gluteus maximum & tensor fasciae latae form a
large muscular complex with the Iliotibial tract
29
Tensor Fascia Latae OIAI
O: ASIS I: iliotibial tract A: flexes, internally rotates, abducts the thigh at the hip I: superior gluteal nerve
30
Gluteus Medius OIAI
O: gluteal fossa of the iliac wing I: greater trochanter of the femur A: abduction, internal rotation (anterior fibres), external rotation (posterior fibres) of the thigh at the hip I: superior gluteal nerve
31
Gluteus Minimus OIAI
O: gluteal fossa of the iliac wing I: greater trochanter of the femur A: internal rotation, abduction of the thigh at the hip I: Superior gluteal nerve
32
Piriformis OIAI
O: anterior surface of the sacrum I: greater trochanter of the femur A: external rotation, abduction of the thigh at the hip I: branches of the sacral plexus
33
Piriformis clinical function
close to superior/inferior gluteal nerve and the pudendal nerve which are detrimental to sexual function
34
Superior Gemellus OIAI
O: spine of the ischium I: greater trochanter of the femur A: external rotation, abduction of the thigh at the hip I: branches of the sacral plexus
35
Inferior Gemellus OIAI
O: tuberosity of the ischium I: greater trochanter of the femur A: external rotation, abduction of the thigh at the hip I: branches of the sacral plexus
36
Obturator Internus OIAI
O: obturator membrane I: greater trochanter of the femur, trochanteric fossa A: external rotation of the thigh at the hip I: branches of the sacral plexus
37
Quadratus Femoris OIAI
O: tuberosity of the ischium I: intertrochanteric crest of the femur A: external rotation, adduction of the thigh at the hip
38
Biceps Femoris long head OIAI
O: tuberosity of the ischium I: head of the fibula, lateral condyle of the tibia A: extension of the thigh at the hip, flexes leg at the knee, laterally rotates a fixed leg I: tibial nerve
39
Biceps Femoris short head OIAI
O: linea aspera I: head of the fibula, lateral condyle of the tibia A: flexes the leg at the knee, laterally rotates a fixed leg I: common peroneal nerve
40
Semitendinosus OIAI
O: tuberosity of the ischium, sacrotuberous ligament I: pes anserinus A: extends the thigh at the hip, flexes/internally rotates the leg at the knee I: tibial nerve
41
Semimebranosus OIAI
O: tuberosity of the ischium I: medial condyle of the tibia A: extends the thigh at the hip, flexes/internally rotates the leg at the knee I: tibial nerve
42
Lateral femoral intermuscular septum seperates
the anterior and posterior compaterments of the thigh
43
Posteromedial femoral intermuscular septum seperates
the medial and posterior compartment of the thigh
44
anteromedial femoral intermuscular septum seperates
the medial and anterior compartments of the thigh
