A comparison of outcome scores in os calcis fractures
1Adelaide and Meath Hospital, Tallaght, Dublin.
Background:
Of over 20 different scoring systems to evaluate outcome following calcaneal fracture, the Maryland Foot Score has broad current acceptance. A general health survey, the Short Form 36 (SF 36) has also been used.
Aims:
The study compared two scoring systems for assessing the outcome of open reduction and internal fixation of displaced intra-articular calcaneal fractures.
Methods:
Over a four-year period, 31 displaced intra-articular calcaneal fractures were categorised by the Sanders classification and treated by open reduction and internal fixation. Outcome was assessed by the Maryland Foot Score and by the Short Form 36 (SF 36) general health questionnaire.
Results:
Thirty-five per cent of fractures were Sanders class 2, 57% were class 3 and 8% were class 4. The average follow-up was 2.5 years (range 1-4 years). Using the Maryland Foot Score, seven fractures had an excellent result, 13 had a good result, six had a fair result and one was a failure. There was a correlation between pain (coefficient = 0.780, p < 0.001) and physical function (coefficient = 0.638, p < 0.001) with the appropriate sections of the SF 36.
Conclusion:
The Maryland Foot Score measures what it attempts to measure and therefore it has content validity for pain and physical function.
