Q

What angle is used to diagnose Genu Varum or Genu Valgum?

A

Q angle (quadraciep angle)

~10 to 14 degrees (Males) ~15-17 degrees (females)

Runs from patella to ASIS and from middle of patella to tibial tuberosity.

Similar to angle of inclination. Helps determine proper alignment between thigh and leg.

Q

What is the correct order of ossification of the cuniforms from earliest to latest?

A

Lateral cuniform, medial cuniform, intermediate cuniform

18
Q

What feature give us right and left on the Tibia? Also identify what Tibia it is Right or Left?

A

Medial articular facet(MAF) is larger and less circular than the LAF

Left Tibia

19
Q

What is the Dematome found along the medial malleolus of the Tibia?

A

L4

20
Q

What dermatome is found at the hallux toe?

A

L5

21
Q

The Navicular tubercle is located in what direction ?

A

Inferior Medial

22
Q

What dermtome would be found at the level of the patella ?

A

L3

23
Q

A Patient presents with pes cavus and medial rotation of the tibia, what will be the result?

A

In-toeing with a high arch foot

24
Q

How many surfaces of the tibia give orgins to muscles ?

A

Two

Lateral Surface(Tibialis anteior muscle and Extensor digitorum longus muscle(Lateral condyle))

Posterior Surface (Flexor digitorum longus and Soleus muscle) Inferior to Soleul line

25
Q

At week 8, the embryo’s feet are in what postion?

A

Plantar Flexed and supinated

26
Q

What is the dermatome of the lateral malleolus?

A

L5

27
Q

The skin ligaments attaches what two structures?

A

Dermis and Deep Fascia

28
Q

What muscle groups will be recruited at each joint during heel strike to offset the effect of ground reaction force and keep the body moving? Hip? Knee? Ankle?

A

At Hip: Hip extensors

At Knee: Knee extensors

At Ankle: Ankle dorsiflexors

29
Q

What muscle groups will be recruited at each joint during Toe-Off to offset the effects of ground reaction force and keep the body moving forward? Hip? Knee? Ankle?

A

Hip: Flexors

Knee: Extensors

Ankle: Planter Flexion

Apropulsive or Calcaneal gait

Weakness of the ankle planter flexors can result in insufficent propulsion.

There will be no toe-off, but the entire foot will leave the ground at once.

30
Q

Embroynoic dorsal surface muscles perform what?

A

Extension and Eversion

31
Q

What ligaments prevent hip extension?

A

Ischiofemoral and iliofemoral

32
Q

What Structure attaches at the anterior intercondylar area?

A

ACL

Remember APEX

Anterior to Posterior External

33
Q

What dermatone is found at the heel?

A

S1

34
Q

If a patient has lost the capability of ankle dorsiflexion, how will he/she compensate during the swing phase and in prepartion for heel stirke?

A

High Steppage Gait

  • Knee lifted high
  • Toe-Strike
  • Muscle atrophy
  • Sometimes toe of show is worn
35
Q

What type of joint is the distal Tibiofibular joint?

A

Syndesmosis

36
Q

What is the order of fusion of the secondary ossification centers of the femur?

A

Lesser Trochanter(18 years)

Greater Trochanter (18-19 years)

Head(18-20 years)

Condyles (20-22 years)

37
Q

How many Secondary Ossfication centers does the Tibia have ? When do they appear and when do they fuse with diaphysis?

A

2 sometimes 3(Tibial tuberosity)

Proximal: @birth (Fuse @ 13-19)

Distal: 8-10 Months After birth (Fuse @ 14-18 years)

38
Q

When do primary and secondary ossfication begin in the fibula?

A

Primary 8 weeks in utero

Secondary 12-18 years

39
Q

When does the fibula primary and secondary ossifications appear?

A

Primary: 8-9 weeks in utero

Secondary: Proxmial 3-5 years

Distal 9-22 months

They fuse with primary: Proximal 12-20 years old

Distal 12-20 years old. Can happen btw 12- 20 years

40
Q

If the patient is in-toeing what condition may they have? (in regards to the Tibia)

A

Medial/internal Tibial torsion

Medial malleoli are oriented posteriorly
