ABSTRACT
Objective:To explore whether the deep deltoid ligament (DL) rupture affects the mid-term clinical efficacy of pronation-external rotation (PER) ankle fracture or not.Methods:A ret-rospective study was conducted to analyze the clinical data of 50 patients with ankle fracture of PER type Ⅲ or Ⅳ who had been treated at Department of Orthopedic Trauma, Beijing Jishuitan Hospital from January 2013 to December 2014.They were 37 males and 13 females with an average age of 30.2 years(from 16 to 68 years). According to their type of medial ankle injury, the patients were divided into 2 groups.The experimental group, consisting of 28 patients with deep DL rupture but no medial ankle fracture, did not undergo DL repair operation; the control group, consisting of 22 patients with supracollicular medial malleolar (SMM) fracture but no deep DL rupture, underwent open reduction and internal fixation (ORIF) for SMM.Both groups were treated with ORIF of fibular fracture in addition to syndesmosis screw fixation.The 2 groups were compared in terms of the medial malleolus space and distal tibiofibular space on the imaging exams at more than 6 months, and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analog scale (VAS) pain scores at the mid-term follow-ups.Results:The differences between the 2 groups in gender, age and mode of concomitant subluxation or dislocation were statistically significant ( P<0.05), but there were no sig-nificant differences between the 2 groups in injury violence, height of fibular fracture line, presence of total dis-location, rate of posterior malleolus fracture, rate of posterior malleolus fixation, implant removal, or operation time ( P>0.05).Imaging exams were conducted for 38 patients at 6 or more months after surgery.The medial malleolus space was 3.7 mm and the distal tibiofibular space 4.5 mm for the 21 cases in the experimental group; the medial malleolus space was 3.4 mm and the distal tibiofibular space 4.4 mm for the 17 cases in the control group.The 3-year follow-up AOFAS scores of the experimental group and the control group were 98.3 and 94.6 respectively; VAS scores were 0.4 and 1.5; the 5-year follow-up AOFAS scores of the experimental group and the control group were 97.1 and 93.6 respectively,and VAS scores were 0.5 and 1.2 respectively.Logistic regression analysis of ordered multi-classification showed that the AOFAS and VAS scores at 3-year and 5-year follow-ups had no significant correlation with the deep DL rupture for the patients<45 years old( P>0.05).Patient age was correlated with the 5-year follow-up AOFAS scores ( P=0.021). Conclusion:In ankle fracture of PER type Ⅲ or Ⅳ treated with lateral malleolar and syndesmosis screw fixation, nonoperative treatment of the deep DL rupture may not influence the mid-term clinical efficacy for the patients less than 45 years old.
ABSTRACT
OBJECTIVE@#To analysis clinical effects of open reduction and internal fixation in treating Gustilo type I and II patients with open distal humeral fracture.@*METHODS@#From 2013 May to 2017 June, 24 patient with Gustilo grade I and II open distal humeral fractures were treated with open reduction and internal fixation, including 20 males and 4 females, aged from 14 to 65 years old with an average of (41.3±13.1) years old. According to Gustilo classification, 16 patients were type I, 8 patients were typeII. Range of motion, complications and secondary surgery were recorded; elbow function were evaluated with VAS (visual analogue scale), MEPS (Mayo elbow performance score) and QuickDASH (quick disabilities of the arm, shoulder, and hand) at 12 months after operation.@*RESULTS@#All patients were followed up from 15 to 60 years with an average of (34.1±11.9) months. VAS score was 0(0, 2); flexion and extension ranged from 50 °to 145° with an average of (115.2±26.1)°; the range of rotation ranged from 100° to 160° with an average of (147.7±17.0)°. MEPS score was for 75 to 90 (90.0±9.1), and 14 patients got excellent result, 10 patients moderate. Quick DASH score was 4.6(0, 14.8). There were 22 patients occurred complications, such as ulnar nerve symptom and internal fixation irritation, and 10 patients accepted the second operation.@*CONCLUSIONS@#Open reduction and internal fixation is a safe and efficient method in treating Gustilo type I and II patients with open distal humeral fractures, which has an advantages of good range of movement and function score.

<p><b>Background</b>In treatment of ankle fracture, intraoperative stress tests are used to assess the syndesmotic injury and instability. However, the optimized timing of the strees test should be applied whether in pre- or post-bony fixation during operation is seldom be reported in previous studies. The different strategies on stress test timing would exhibit opposite results within a type of pronation-external rotation (PER) fractures with supracollicular medial malleolar (SMM) fractures. This study was designed to assess the 3-year functional outcomes of the special PER fractures with or without a syndesmotic transfixation based on the results of two different intraoperative stress test strategies.</p><p><b>Methods</b>This retrospective cohort study included 61 PER injury-Weber C ankle fractures combined with SMM fractures who were treated in Beijing Jishuitan Hospital between 2013 and 2014 and followed up for 3 years. Stress test was performed twice intraoperatively. A positive intraoperative stress test before bony fixation and a negative intraoperative stress test after bony fixation were found in these included patients. Twenty-nine patients (Group 1) were treated without a supplemental syndesmotic screw fixation, according to the negative intraoperative stress test after bony fixation, while 32 patients (Group 2) were treated with an additional syndesmotic screw fixation based on the positive intraoperative stress test before bony fixation. The American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and Visual Analog Scale (VAS) for pain scores were the main measurements of outcome. The statistical index of demographic data, fracture morphologic data, time interval of follow-up, AOFAS and VAS were recorded and assessed by SPSS 21.0 software through Fisher exact tests and one-way analysis of variance. The associations between the main outcomes and influential factors were evaluated by linear regression models.</p><p><b>Results</b>We observed no difference in the distribution of age, sex, presence of associated posterior malleolus (PM), fracture dislocation, and fixation of associated PM between two treatment groups. With the numbers available, no statistically significant association could be detected with regard to the AOFAS (Group 1 vs. Group 2, 96.72 ± 6.20 vs. 94.63 ± 8.26, F = 1.24, P = 0.27) and VAS (Group 1 vs. Group 2, 1.47 ± 2.14 vs. 0.72 ± 1.49, F = 2.44, P = 0.12) in association with two strategies.</p><p><b>Conclusions</b>The present study indicates no difference to the use of the syndesmotic screw in terms of the functional outcome between syndesmosis transfixation and no-fixation patients among PER-Weber C ankle fracture patients with SMM fracture after 3-year follow-up. More attention should be paid to pre- and post-bony-fixation intraoperative stress tests and the morphology of medial malleoli fractures in ankle fractures.</p>
