Q

Which matrix is responsible for forming the nail plate and about 90% of total nail growth?

A

germinal matrix

17
Q

Which matrix forms the ventral nail and adds thickness?

A

sterile matrix

17
Q

What stage of Mozena classification of ingrown nail has nail fold 3 mm or higher?

A

stage IIb or 3

18
Q

What is the difference between nail avulsion and matrixectomy?

A

A nail avulsion removes part or all of the nail from the nail bed. The other is a permanent nail avulsion.

19
Q

Surgical procedure performed by an L-shaped wedge resection of tissue including the nail matrix and the offending tissue border.

A

Frost matrixectomy

20
Q

A surgical procedure which is an avulsion of the entire nail plate

A

Suppan matrixectomy

21
Q

A ___ procedure is used when you have an ingrown toenail with hypertrophied soft tissue border.

A

Winograd

22
Q

This matrixectomy is described as an H-shaped incision.

A

Zadik

23
Q

What is a surgical consideration before a matrixectomy is performed?

A

HIV/CD4 <200. Platelet< 50. Glucose <200

24
Q

**controls joint motion
**rigid/semi-rigid
**restricts forces acting on foot
**shell ends proximal to the met heads
**top cover optional

A

functional orthotic

25
Q

**No joint motion control
**Redistributive forces
**Usually softer materials
**Full length
**Top cover needed

A

accommodative orthotic

26
Q

What is Root Theory?

A

Structural deformities lead to altered foot function, which leads to compensation, which leads to pathology

27
Q

What is the general idea of the tissue stress theory?

A

It is based on the patient’s CC. It takes the pathology/structure into account in the beginning and then design the orthotic.

28
Q

In which position should the MTJ be in for a negative suspension plaster cast?

A

dorsiflexed and everted (locked)

29
Q

What marks do we want to transfer onto a plaster cast to help the lab make a good device?

A

skin lines, heel bisection

T1

31
Q

This time for MRI is good for evaluating pathology and water (inflammation)

A

T2

32
Q

A

MSK injuries

33
Q

When is contrast MRI helpful?

A

infection, tumors, vascular malformations

34
Q

Which imaging technique is most harmful to the patient?

A

CT

35
Q

What is angle B on this DP? What is normal?

A

1st intermetatarsal angle; 8-12 degrees

36
Q

What is angle A on this DP? What is normal?

A

hallux abductus angle (HAA), 1st MTP angle; 0-15 degrees

37
