ABSTRACT
Objective To explore the clinical efficacy of secondary unreamed intramedullary nailing following primary external fixation for open tibial shaft fractures.Methods From March 2011 to June 2014,we treated 28 open tibial shaft fractures.They were 17 men and 11 women,aged from 21 to 62 years (average,38.2 years).After thorough debridement,the tibia was stabilized temporarily with external fixation.The wounds were handled with primary closure or secondary repair with skin grafts or tissue flaps.After the wounds healed,the external fixation was replaced by unreamed intramedullary nailing.Fracture union and complications were documented.The clinical efficacy was evaluated at the final follow-ups according to the Johner-Wruhs scoring system.Results All the 28 patients were followed up for 12 to 18 months (average,13.5 months).Bony union was achieved in all after 4 to 15 months (average,4.9 months).Delayed union was observed in 4 cases which were healed after dynamic fixation.There was no deep infection,nail breakage,malunion or limb shortening in any one.Mild knee pain was reported by 5 cases after surgery.According to the Johner-Wruhs criteria,18 cases were excellent,7 good,and 3 moderate,giving an excellent to good rate of 89.3％.Conclusion Primary external fixation and secondary unreamed intramedullary nailing can result in good fracture union with satisfactory biomechanical stability and favorable early rehabilitation in the treatmeut of open tibial shaft fractures.
ABSTRACT
Objective To evaluate the therapeutic efficacy of hook plate and fascia lata graft in management of chronic acromioclavicular joint dislocation.Methods From May 2012 to March 2014,a total of 16 cases of chronic acromioclavicular joint dislocation (Rockwood type Ⅲ) were treated with hook plate and fascia lata graft.They were 10 men and 6 women,from 19 to 57 years of age (mean,34.7 years).Seven cases were at the left side and 9 at the right side.All injuries resulted from direct violence.The time from injury to surgery ranged from 8 to 54 weeks (mean,12.4 weeks).At the final follow-ups,the shoulder function was assessed using the Quick Version of the Disabilities of the Arm,Shoulder and Hand Score (DASH) and visual analogue scale (VAS),and the efficacy using Karlsson's evaluation system.Results All surgical wounds primarily healed.The dislocation of acromioclavicular joint was corrected,without any vascular or neural damage.The patients were followed up for an average of 12 months (from 6 to 18 months).No plate breakage,screw loosening or redislocation was observed.The DASH and VAS scores of the shoulder at the final follow-ups (25.42 ± 8.34 and 2.22 ± 1.70,respectively) were significantly improved,compared with the preoperative ones (43.72 ± 12.35 and 6.33 ± 1.37,respectively) (P ＜ 0.05).According to the Karlsson's criteria,10 cases were excellent,4 good and 2 moderate.Conclusion In management of Rockwood type Ⅲ chronic acromioclavicular joint dislocation,hook plate and fascia lata graft can restore dynamic balance and stability of the acromioclavicular joint,resulting in solid fixation,early joint motion and limited complications.
