The Study On The Evaluation Of Different External Fixation Posture Of Pronation Fracture Of Ankle

Objective:To evaluate the clinical efficacy of pronation fracture of ankle with two different external fixation posture, inversion dorsiflexion posture and neutralism dorsiflexion posture, to work out the better external fixation posture.Method:60cases of pronation fracture of ankle consistent with selection standards and followed up with periodical visits were chosen for the test.They were randomly assigned to two groups, with30cases in each group.One group treated by manipulative reduction was fixed by U plaster slab at the posture of inversion dorsiflexion, the other one treated by manipulative reduction was fixed by U plaster slab at the posture of neutralism dorsiflexion.Then the AOFAS score and the Curative Effect of Traditional Chinese Medicine Illness Diagnose Standardization score and the Liu Lateral Ankle Ligament Injury Evaluation Criterion score were retrospectively adopted and analysed to evaluate the short—terms clinical efficacy.Results:1.Each case was followed up with visits for6to18months.An average of10±3.42months.The two groups had no obvious variance in gender and age.2.The AOFAS Scoring:The Score of inversion dorsiflexion posture group were from82to100,91.50±5.81in average while the neutralism dorsiflexion posture group were from76to100,86.23±5.91in average.There were obvious variance between the two groups(P<0.05).3.the Curative Effect of Traditional Chinese Medicine Illness Diagnose Standardization: The inversion dorsiflexion posture group:Cure:25cases, Improvement:5cases, Unhealed:0cases., Recovery rate:83.33%; The neutralism dorsiflexion posture group:Cure:21cases, Improvement:9cases, Unhealed:0cases., Recovery rate:70.00%; There were obvious variance between the two groups(P<0.05).4.The Liu Lateral Ankle Ligament Injury Evaluation Criterion score:The inversion dorsiflexion posture group was85.31±5.34in average while the neutralism dorsiflexion posture group was79.49±4.54in average.There were obvious variance between the two groups(P<0.05).5.Postoperative complications:The inversion dorsiflexion posture group was0cases while the neutralism dorsiflexion posture group was2cases.There had no obvious variance between the two groups(P>0.05). Conclusion:The clinic efficacy of pronation fracture of ankle treated by manipulative reduction and fixed by U plaster slab at the posture of inversion dorsiflexion is better than the one at neutralism dorsiflexion.
