Objective@#To investigate the clinical efficacy of tight suturing for shortening healing scar tissues in repair of Myerson type III old rupture of Achilles tendon.@*Methods@#A retrospective case series study was performed to analyze the clinical data of 16 patients with Myerson III type chronic Achilles tendon ruptures admitted to Sports Hospital Affiliated to Chengdu Sport University from January 2015 to December 2017. All of the patients were males with sports injuries, aged 19-71 years (mean, 40.6 years). The Achilles tendon defect was 5-7 centimeter (mean, 5.2 centimeter). The patients received tight suturing and shortening healing scar tissue for the repair. The operation time and surgical wound size were recorded. The clinical efficacy was evaluated by Amer-Lindholm standard and American 0rthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. Meanwhile, the complications such as wound infection, Achilles tendon re-rupture, heel lifting weakness, muscle strength decline, ankle dysfunction, lameness and symptoms of sural nerve injury were recorded.@*Results@#All patients were followed up for 11-41 months, with an average of 26 months. The operation time ranged from 25-51 minutes, with an average of 37 minutes. The incision was 4-12 cm, averaging 7 cm. According to the Amer-Lindholm standard, 14 patients were graded as excellent and two were graded as good, with the excellent and good rate of 100%. AOFAS ankle-hindfoot score increased from (42.7±6.8)points before operation to (95.1±4.9)points at the last follow-up (P<0.05). During the follow-up, there were no complications such as infection, Achilles tendon rupture, heel lifting weakness, muscle strength decline, ankle joint dysfunction, lameness and gastrocnemial nerve injury.@*Conclusion@#For Myerson type III old rupture of Achilles tendon, tight suturing for shortening healing scar tissue can increase the postoperative function scores without wound infection or complications.

Objective To investigate the clinical effect of posterior short-segment pedicle screw reduction and fixation without fusion in treatment of thoracolumbar mono-segmental compression fractures.Methods Thirty cases of thoracolumbar mono-segmental compression fractures admitted from January 2009 to February 2010 were assigned to single posterior pedicle screw fixation (screw group,n =15) and posterior pedicle screw fixation with posterolateral fusion (fusion group,n =15) according to random number table.Clinical results in the two groups were assessed based on Cobb' s angle,anterior vertebral body height ratio (％) and Oswestry disability index (ODI) before operation,after operation,prior to the removal of implant and at the latest follow-up.Results All the cases were followed up for average 24 months.Both operation time and blood loss were less in screw group than in fusion group [(76.58 ±12.67) min vs (116.29 ± 17.45) min,P ＜ 0.01 ; (287.54 ± 30.76) ml vs (480.34 ± 100.54) ml,P ＜0.01],whereas there were no statistical differences between the two groups in aspects of Cobb' s angle and anterior vertebral body height ratio before and after operation,prior to the removal of implant as well as at the latest follow-up.Moreover,no statistical difference of ODI was noted between the two groups prior to the removal of implant and at the latest follow-up.Conclusion Posterior pedicle screw fixation without bone grafting achieves similar effects with pedicle screw fixation with bone grafting.
