Chronic Osteomyelitis of Foot

• Foot : unique environment for development of infections

• The foot’s environment is modified by footwear, trauma,

systemic illness, and poor soft tissue coverage

• Each of these factors : susceptibility of foot to infection

• Most Common cause in Foot : Diabetic ulcer

• Non diabetic foot infection : open fracture, after internal

fixation, puncture wound

Purpose

To evaluate the clinical characteristics

of COM involving the foot & ankle

To analyze the treatment outcomes following

debridement, dead space control, and

arthrodesis based on invasion of adjacent joint

MATERIALS

• Sep. 2004 - Mar. 2007

• 15 patients treated for COM in Foot & ankle

- F/U > 24m, M : F = 10 : 5

- Exclusion : immune compromised, DM

- No vascular problem

• Age : Mean 46.7yrs (25 – 72yrs)

• All pts. referred from other hospital

• Period of Tx. for COM : Mean 3.07yrs (6 -13yr)

Preoperative evaluation • ESR/CRP : 53.56 (2-120) / 2.86 (0.1-11.86) at OPD visit

• MRI for accurate extent, invasion of adjacent joint

forefoot : 1

Midfoot : 1

Distal tibia : 6

Ankle : 3

Calcaneus : 4

Surgical Technique ① 1st stage : Extensive margianl excision - until normal tissue, synovectomy & joint debridement - Dead space control : antibiotic-loaded cemet spacer ② 2nd stage : Arthrodesis with BG

Antibiotics mixed cement : 8 cases Bone graft : 10 cases curettage only : 2 cases (TBc of distal tibia, cuboid) cementing only : 1case (distal tibia) partial calcanectomy : 1case

Arthrodesis : 5cases - ankle fusion : 2cases - subtalar fusion : 1case - ankle & subtalar fusion: 1 - TMT fusion : 1case

Results

Cause Pathogen Fracture : 10 - open fx. : 5 - post. OR/IF : 5 Post. Arthroscopy : 1 Post. Flap surgery :1 Punctuating wound : 1 Recurred AOM : 1 Hematogeous : 1(TBc)

MRSA : 4

Pseudomonas : 4

MSSA, Enterobactor,

M. tuberculosis : 1

Burkholderia, anaerobe : 1

No growth : 1

Results

• Average of 2 surgeries (1- 3)

• Hospitalized for a mean period: 39.1 day(14-116)

• Keep cement spacer : mean 27day(14-67)

• 14/15pts : no recurrence

• 1 pt : iatrogenic septic arthritis : BKA

• Mean ESR/CRP : 14.7/0.13 at final F/U

CASE I M/41 9yrs ago TA

distal tibia open fx.

>10times I&D , Flap

ESR/CRP : 18/0.44

Culture : pseudomonas

CASE II M/56 3month ago

ankle open Fx. – D/L

>10 times debridement

pus discharge, medial

soft tissue defect

AVN of talus

ESR/CRP : 120/3.61

Culture : MRSA

SUMMARY

• M/C cause : fractures

• Extrinsic cause > intrinsic cause

• M/C pathogen: MRSA, pseudomonas

• Good result after staged operation

(wide debridement + dead space control)

• Check the involvement of adjacent Joint

selective joint arthrodesis

Chracteristics Of COM involving foot & ankle

CONCLUSION

Wide debridement

Dead space control

Selective Joint Arthrodesis

For successful Treatment Of COM

involving foot & ankle
