Q

Yates 2015

A

6 meta-analyses of Jones Fx fixation: IM pinning vs Conservative

  • lower rate non-union in sx tx (0-11%) (vs 11-50% in conservative)
  • faster return to sports and normal activity in sx
  • complications: more complications in non-op group (re-fx, delayed union, malunion) (31 to 8.5%)
  • no diff in satisfaction b/w groups

Q

Yu 2002 pre-dislocation syndrome

A
  • positive vertical stress test result present with dorsal translocation of prox phalanx 2 MM above met head
  • progressive subluxation/dislocation of lesser digit with pain during ambulation, better with rest
  • feel like “stone bruise” or “lump” on bottom of foot with swelling at base of toe, more impressive plantarly
  • excruciating pain just distal and plantar to met head that is disproportionate to any other objective clinical findings

Q

Arntz 1988

A

development of post-traumatic arthritis s/p ORIF of lisfranc injuries all of whom had intra-articular or peri-articular fxs w/ anatomical or nearly anatomical reduction achieved intra-op …. was directly related to the DAMAGE TO THE ARTICULAR SURFACES OR TO INADEQUATE REDUCTION, OR BOTH

Q

Coetzee 2006

A

compare ORIF and primary arthrodesis in primarily ligamentous Lisfranc injuries –> primary stable arthrodesis of the medial and central columns had better short and medium term outcomes (2 year f/u) than ORI
- arthrodesis - back to 92% of preinjury level vs ORIF only 65%

Q

Astion 1997

A
  • arthrodesis of TNJ severely limited the motion of the STJ and CCJ to about 2 deg (STJ: 8% of pre-op value), and limits PTT to 25% of original value
  • arthrodesis of the CCJ had little effect on the ROM of the STJ, and it reduced the ROM of the TNJ to a mean of 67% of preop value
  • arthrodesis of the STJ reduced motion at the TNJ to 26% and CCJ to 56%

Q

Manoli and Weber 1990

A
  • added “9th calcaneal” compartment for foot compartments:
  • medial, lateral, superficial, adductor, 4 x interossei, calcaneal (contains QP and communicates with the deep posterior leg compartment through the retinaculum behind medial mal, following NVS and tendons

Q

Wukich 2008 - Management of Ankle Fxs in Pts with DM

A
  • prolonged NWB and subsequent Protected WB are recommended following both op and non-op tx of ankle fxs in pts with DM
20
Q

Kuwada 1995

A

Types I-IV AT rupture and suggested treatments

* average return to pre-injury activity level was 5.1 months (following classification and corresponding treatment)

21
Q

Cronin 2003

A
  • pts with wide pre-op IMA –> 1st MTPJ changed preop IM to postop IM by 8.22 deg
  • pts with severe HAV and 1st MTPJ degeneration – arthrodesis can significantly correct IMA w/o addition of basal osteotomy
22
Q

Dickhaut 1984

A

minimum levels of albumin and TLC to heal?

  • albumin: 3 g/dl
  • TLC: 1500
23
Q

Who studied the relationship between ABI and healing and what did he/them find?

A

Wagner

ABI >/= 0.45 for DM

24
Q

Wyss, Harrington & Burgess, JBJS, 1988

A

minimum TcPO2 needed for healing = 30 mmHg

25
Q

Myerson 1999 Charcot

A
  • in acute phase of skin necrosis from pressure of dislocated bone or if other skin problems = likely to occur in casting –> sx indicated, also for marked dislocation that likely to cause later problems –> can fixate if
26
Q

Simon 2000 Charcot

A

primary arthrodesis in pts with early stage 1 charcot = good results – = alternative to conservative non-op management in these pts

27
Q

History of Charcot in the literature

A
  • Musgrave = 1st to report neuropathic OA due to venereal disease
  • Jean Marie Charcot = French neurologist - described the neuropathic component and linked it to syphilis
  • Jordan linked condition to DM
  • Volkman, Virchow, and “German School” = neurotraumatic theory
  • Edmonds - NV theory
28
Q

Armstrong support for TTC for Charcot

A

reduced stride length and cadence decreases possibility of developing charcot in other foot

29
Q

Bibbo 2014 Calc Fx

A
  • suggest that either through direct injury or 2/2 thrombosis following DIACF –> large portion of blood supply to anterolateral flap in LEA may be disrupted
    • may want to doppler LCA prior to sx ( if patent, normal LEA, if not – may want to consider alt approach, e.g., sinus tarsi)
30
Q

Sanders 1993 Calc Fx

A

Type 4 – results usually poor – may want to consider primary arthrodesis STJ

31
Q

Reudi and Allgower 1969

A

4 key principles of pylon fx reduction:

  1. restoration of length of fibula
  2. reconstruction of articular surface of distal tibia
  3. filling in the defect from impaction using cancellous autografts
  4. support of the medial side of the tibia by plating to prevent a late varus deformity
32
Q

Ramsey and Hamilton 1976

A

with 1 mm of lateral talar displacement, there was 42% decrease in tibiotalar contact
- majority of decrease in contact occured in 1st 1mm of deformity

33
Q

Yablon 1977

A
  • lateral malleolus is the key to the anatomical reduction of the bimalleolar fx, b/c the displacement of the talus faithfully follows the lateral mall
34
Q

Schaffer and Manoli 1987 for antiglide plate

A
  • antiglide plate advantages over lateral plate: decreased ST dissection, no chance for screws to enter joint, antiglide plate had a much higher torque/load to failure than traditional lateral plate! (stronger)
35
Q

Hoiness 2004 Syndesmosis Fixation

A
  • no significant differences b/w 2 x 3.5 tricortical and 1 x 4.5 quadricortical in terms of functional score, pain, and DF after 1 year
  • 4.5 screws were routinely removed after 2 mo, 3.5 only if symptomatic
36
Q

McLaughlin : Posterior Mal Fx

A

fixate posterior mal fx when >25% artic surface involved

37
Q

Swanson Study 1992 Talar Neck Fx Fixation

A

2 cancellous screws Postero–>Anterior dxn = strongest

but also riskier b/c harder to visualize

38
Q

Raikin

A
  • OCD lesions - most common location is central (80%), medial 62%, lateral 34% – so mediocentral then laterocentral
39
Q

McDonald 1977

A

Described 25% rule for posterior mal fxs

40
Q

Q

1st person to describe triple arthrodesis

A

ryerson

42
Q

1st person to describe charcot in diabetics

A

jordan

43
Q

44
Q

takagi

A

first described arthroscopy

45
Q

heller and vogel

A

1st to describe arthroscopy in podiatry
