24
Q

Etiology of Haglund’s deformity

A
  • compensated RF varus
  • compensated FF valgus
  • Rigid plantarflexed 1st ray
25
Q

Conservative options for Haglund’s deformity

A

-open back shoes, heel lift, orthotics, NSAIDs, steroid injections

26
Q

Surgical options for Haglund’s deformity

A
  • Extracorporeal shock wave therapy with eccentric loading
  • Achilles lengthening
  • Remove bursa, resection of bony prominence
  • Keck and Kelly osteotomy
27
Q

Describe Keck and Kelly procedure

A
  • remove sagittal wedge in calcaneus

- Useful for structural cavus and high CIA

28
Q

Anatomy of the Achilles tendon

A
  • strongest and thickest tendon in the body
  • Tendon rotates 90 degrees as it courses distally to insert on calcaneus. Soleus inserts medially to gastroc.
  • Achilles does not have synovial sheath but instead a paratenon to allow for gliding activity
  • Sural nerve crosses tendon 11cm proximal to insertion
29
Q

Describe paratenon

A

similar to tendon sheath, majority of blood supply, preserve during surgery

30
Q

Describe mesotenon

A

tissue connection tendon to fibrous sheath

31
Q

describe the epitenon

A

outer covering of tendon within sheath

32
Q

describe the endotenon

A

tissue carrying blood vessels surrounding small collagen bundles

33
Q

Stages of tendon healing (4)

A

1) Inflammatory: neutrophil/macrophage infiltration, increased vascularity (first week)
2) Proliferative: synthesis of type 3 collagen (second week)
3) Remodeling phase: decrease in collagen, alignment of collagen fibers in direction of stress (6-10weeks)
4) Maturation phase: fibrous (10weeks-1 year)

34
Q

Major areas of blood supply for Achilles tendon

A
  • Myotendinous junction
  • Paratenon
  • At the insertion of calcaneus
35
Q

Etiology of achilles tendonitis /tendonosis

A

-mechanical overload due to :

—biomechanics- cavus foot, hyperpronation, equinus

—lifestyle- improper footwear, aging, systemic conditions

36
Q

Clinical presentation for achilles tendinitis

A
  • Noninsertional: noticeable posterior bump, thickened Achilles tendon at watershed area
  • Insertional: fist step achy pain, pain worse going up a hill/stairs, shoe irritation
37
Q

Conservative treatment options for Achilles tendinitis

A
  • activity modifications
  • Meds: NSAIDS, steroids, topical antiinflammatory
  • Orthotics: CAM walker, Heel lift
  • Stretching: eccentric and concentric
38
Q

Surgical treatment options for Achilles tendinitis

A
  • Tendoscopy
  • Release of adhesions
  • Debridement of pathologic tissue
  • Exostectomy
  • Remove retrocalcaneal bursa
  • FHL tendon transfer
39
Q

Where do Achilles tendon ruptures tend to occur

A
  • In the watershed area approximately 2-6 cm proximal to insertion of calcaneus
40
Q

Etiology of Achilles tendon rupture

A
  • Same as those causing AITC
  • Trauma
  • System: hyperlipidemia, gout, RA, CKD
41
Q

Exam findings to diagnose Achilles tendon ruptures

A
  • Mattle’s test: pt prone with knee bent
  • Simmond’s test: pt prone
  • Thompson squeeze test: patient prone, knee bent and squeeze calf
  • Hatchet strike defect
  • Palpable dell
  • Unable to PF
42
Q

Radiographic findings for Achilles tendon ruptures

A

Toygar’s angle: should be less than 150
Arner’s sign: insertion of achilles curves away from calcaneus
-Kager’s triangle will be ill defined

43
Q

What classification system is used for Achilles tendon tears

A

Kuwada classification system

  • 1: Partial tear (most common)
  • 2: Complete tear <3cm: Krackow, Bunnel, Kessler stitch
  • 3: Tear is 3-6cm displaced : Autograft, graft jacket
  • 4: Tear >6cm displaced: V-Y gastroc recession, Strayer
44
Q

What protocal claims that conservative treatment does the job

A

Willits protocol states that accelerated functional rehab and nonoperative treatment just as effective as surgical

45
Q

What are the surgical suture patterns for Achilles repair

A
  • Krackow: giftbox suture (suture tied away from rupture site
  • Bunnel: criss cross stitch to prevent shearing of suture through tendon
  • Kessler
