ABSTRACT
Objective To investigate the risk factors for postoperative deep wound infection after open reduction and internal fixation for closed calcaneal fractures.Methods From January 2014 to January 2017,190 patients with closed calcaneal fracture were treated at Department of Traumatic Orthopaedics,Taihe Hospital.They were 118 males and 72 females with an average of 39.8 years (range,from 18 to 73 years).They were divided into a deep infection group and a non deep infection group according to the presence or absence of deep wound infection in the follow-up period.The 2 groups were compared in the general clinical data.In statistical analysis,the related risk factors were first screened by single factor analysis and followed by multivariate logistic regression analysis to identify the independent risk factors associated with the postoperative deep wound infection in patients with closed calcaneal fracture.Results The 190 patients were followed up for an average of 21.3 months(range,from 13 to 31 months).Postoperative deep wound infection occurred in 11 patients,giving an overall incidence of 5.7％ (11 / 190).The single factor analysis showed that the deep infection group incurred significantly longer time for tourniquet and used significantly more conventional extensile lateral approach than the non deep infection group (P ＜ 0.05).There were no significant differences between the 2 groups in general data,injury cause,fracture type,drainage,or incision closure technique (P ＞ 0.05).The multivariate logistic regression analysis revealed that tourniquet time ＞ 80 min (OR=5.949,95％ CI:1.216～ 29.108,P=0.028) and conventional extensile lateral approach (OR =5.414,95％ CI:1.507 ～ 19.452,P =0.01) were independent risk factors fo r the postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Conclusions Tourniquet time and conventional extensile lateral approach may be the independent risk factors for postoperative deep wound infection in patients with closed calcaneal fracture after open reduction and internal fixation.Therefore,it is important to adopt the sinus tarsi approach and control tourniquet time within 80 minutes for prevention of deep wound infection as long as the surgical quality is ensured.
ABSTRACT
Objective To study the technique, clinical effect and safety of endoscopic calcaneoplasty for Haglund disease. Methods Clinical data of 12 patients with Haglund disease having underwent endoscopic calcaneoplasty were collected and retrospectively reviewed. All the patients experienced conservative treatment for 3 to 6 months which was failed and then turned to endoscopic calcaneoplasty. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score before and after operation, patient′s satisfaction and complication were recorded. Postoperative complications were also observed. Results All the patients underwent the operation successfully within 70 min, with 42 min on average, and no complications occurred. All the patients were followed up for 12.4 (8-16) months, the AOFAS ankle-hindfoot score after operation was significantly higher than before operation:94.6 (86-100) scores vs. 58.6 (32-72) scores, and there was statistical difference (P<0.05). After operation, 10 cases were excellent, and 2 cases were good. All patients were satisfied with the surgery, and no recurrence occurred during the follow-up period. Conclusions Endoscopic calcaneoplasty appears to be a safe, minimal invasive and effective surgical procedure for the treatment of Haglund disease.
ABSTRACT
Objective To evaluate the diagnostic value of Achilles tendon rupture by using X-ray plain films and MR images. Methods The plain films and MRI findings in 21 patients with operation proved acute Achilles tendon rupture were analyzed, and every manifestation on MR and operation were compared.Results The Achilles tendon rupture was diagnosed on MRI in all 21 cases. Complete rupture of Achilles tendon was showed in 7 and partial rupture in 14. MRI appearance of the rupture represented as thickening of Achilles tendon, hyperintensity in the tendon, and completely or partly discontinuance of the fibrous bundle. X-ray showed Achilles tendon rupture in 5, suspicious rupture in 12, and normal in 4. Operation showed Achilles tendon complete rupture in 9 and partial rupture in 12.Conclusion MRI can accurately show the degree and location of acute Achilles tendon rupture, which is very helpful for treatment. X-ray is the adminicular method in detecting Achilles tendon rupture and the diagnosis should be depended on MRI to confirm the the acute Achilles tendon rupture.
