The Study On The Evaluation Of Two Kinds Of External Fxation Position Of Pronation-Extorsion Fracture Of Ankle

ObjectiveTo probe into abetter fixed position, comparisons with two manual reductionsof II-IV type pronation-external rotation Fracture of Ankle, fixed in Varus Position of90Degrees Dorsiflexion and Neutral Position of90DegreesDorsiflexion through plaster, and evaluations of their clinical curative effects.MethodSixty patients who have been diagnosed Pronation-external Rotation Fracture of Ankle are randomly divided into two groups of30cases in our experiment. They are also included and excluded in the criteria with regular follow-ups. One group is treated with manual reductions fixed in Varus Position of90Degrees Dorsiflexion through U-plaster, while the other one isfixed in Neutral Position of90Degrees Dorsiflexion. The two groups are used the same conventional adjuvant therapy after entire complex.We will analyze and score the results, referring to AOFAS Ankle-Hindfoot Scale, Standards for Diagnosis and Curative Effects of Chinese Medical Symptoms and Liu, Evaluation Criterion for Collateral Ligament Injury in Lateral Ankle. Through comparati ve statistics and detailed analysis of complications, we will study and evaluate recent curati ve effects of two fixed post ns.Results:1. We do regular follow-ups from6to12months, which averages8±4.42months. There i s no remarkabl e di fference i n gender and age from two groups.2. AOFAS scores:Varus Dora flexion90(?) group scores from83to100points with an average of91.50±6.45points; Neutral Dorsiflexion90(?)group scores from75to100points, with an average of86.87±6.42points Scores between two groups are significantly different (P<0.05).3. Rating from Standards for Diagnosis and Curative Effects of Chinese Medical Symptoms:Varus Dorsiflexion90(?) Group are cured in28cases and improved in2cases. The cure rate reaches93.33%. Neutral Dorsiflexion90(?) Group are cured i n21cases and i mproved in9cases. The cure rate reaches70.00%. Two groups differ significantly in cure rates (P <0.05).4. Liu, Evaluation Criterion for Collateral Ligament Injury in Lateral Ankle. The varus position of90degrees dorsiflexion group gets scores with85.17±7.25points, while the neutral position of90degrees dorsiflexion group scores79.17±7.44points. There are obvious variances between two groups (P<0.05).5. Postoperative complications:Varus Dorsiflexion group with one patient and Neutral Dorsiflexion group with2cases. Comparisons with postoperative complication rates between two groups are not statistically significant (P>0.05).Conclusion1. For II-IV type pronation-external rotation Fracture of Ankle the manipulative reduction can achieve satisfactory clinical effect.2. Complications of two fixed positions in this study recently were smaller, higher security.3. The clinical cure rate of Varus Doraflexion90(?) Group is higher than Neutral Dorsiflexion90(?) Group.4. For comparison ankle functional recovery, The position of Varus Dorsiflexion90(?) is better than the position of Neutral Dorsiflexion90(?).In conclusion, The overall effect of the patients of II (?)-IV(?) of Rronation-extorsion Fracture of Ankle treated with plaster external fixation in Varus Dorsiflexion90(?) Group is better than in Neutral Dorsiflexion90(?) Group. The position of Vans Dorsiflexion90(?) can increase the cure rate in patients with clinical, promote the recovery of ankle function, improve the quality of life of patients, and high safety, and is worthy of clinical application.
