Operative treatment of complex fractures of midshaft clavicle using a locking plate: a comparison be-tween mini-invasive plate osteosynthesis ( MIPO ) and conventional open reduction / 中华创伤骨科杂志

Objective To compare the clinical outcomes of mini-invasive plate osteosynthesis ( MIPO ) and conventional open plating for complex fractures of midshaft clavicle. Methods The authors retrospec-tively reviewed the data of complex fractures of midshaft clavicle ( AO/OTA types 15-B2 and 15-B3 ) which had been treated with MIPO or conventional open plating between January 2010 to February 2016. Forty-one patients were treated with MIPO and 43 with conventional open plating. The 2 groups were compared in terms of incision length, hospital stay, bone union time, postoperative Constant score and Disabilities of the Arm, Shoulder and Hand ( DASH ) score, patients'satisfaction and complications. Results The average follow-up was 21. 2 ± 9. 2 months for MIPO group and 23. 1 ± 11. 8 months for conventional open plating group. The incision length ( 4. 3 ± 0. 5 cm ) , hospital stay ( 7. 7 ± 1. 9 d ) and union time ( 10. 6 ± 3. 2 w ) in the MIPO group were signifi-cantly shorter than those in the conventional open plating group ( 8. 4 ± 1. 3 cm, 9. 6 ± 3. 1 d and 12. 3 ± 3. 9 w, respectively ) ( P <0. 05 ) . The MIPO group had significantly lower incidences of hypertrophic scarring and dysesthesia in the area of incision but significantly higher patients'satisfaction than the conventional open plating group ( P <0. 05 ) . There were no significant differences in the Constant score or DASH score at 3 months, 6 months and the final follow-up ( P > 0. 05 ) . Conclusion In the treatment of complex fractures of midshaft clavicle, although both MIPO and conventional open plating can lead to similar functional outcomes, MIPO may be advantageous over conventional open plating in smaller surgical incision, more rapid fracture union, shorter hospital stay and higher patients'satisfaction.

Treatment of acetabular fractures through the combination approach / 中华创伤骨科杂志

Objective To investigate the combination appr oach used to treat the complex acetab ular fractures.Methods Form January 1998to August 2001,31c ases of acetabular fractures were tr eated through combination of Kocher-Langenbeck a nd ilioinguinal approaches.26case s of them resulted from traffic injur ies,and 5from fall injuries.The average interval from injure to operation wa s 17.6days.The average blood loss wa s1890ml.The average operative duration was 252minutes.According to the classification of Letournel and Jud et,associated fracture types accounte d for 27cases,and simple type 4cases.They were fixed by the reconstructi ve plates and /or plates +lag screws.Results The average follow-up was 20.2month s.According to criteria of Matta,of the 20cases who underwent a natomic reduction,10were satisfac tory while 1unsatisfactory.21case s had excellent and good clinic results,8fair,2poor.Conclusion Because of the advantages of excelle nt ex-posure,convenient reduction,rigid fixation and lower heterotopic ossification,the combination approach is good to treat the complex acetabular fractu res involved the two columns.[

Operative management of type Ⅱ fracture of the distal clavicle / 中华创伤骨科杂志

Objective To introduce an operative method for the treatment of type Ⅱ fracture of distal clavicle. Methods The clavicle and coracoid proc ess were compressively fixed with screw in, and the coracoclavicular ligament wa s repaired in 24 cases of type Ⅱ fracture of the distal clavicle. Results The fractures healed in all the cases with good function of joint, and without screw loosening or traumatic arthritis. Conclusion The operative method is an ideal m anagement for the treatment of adult type Ⅱ fracture of distal clavicle, due t o its easy handling, reliable fixation, exact curative effects and less complica tions.

Treatment of displaced humeral surg ical neck fractures with closed reduction and percutaneous pin fixation / 中华创伤骨科杂志

Objective To summarize the methods and results of treatment of displaced humeral su rgical neck fractures with closed reductio n and percutaneous pin fixation.Methods We reviewed 46patients who had been diagnosed as the displaced hume ral surgical neck fractures and trea ted with closed reduction and percut aneous pin fixation using?2.5mm Kirschner wire with terminal t hread from January 2001to December 2002in our hospital.Results34patients received a complete follow-up.The mean follow-up time was 22months(10to 34months).Evaluation was done with Constant-M urley rating system.The mean absolu te Constant-Murley score was 92(76～100).86%(29/34)of the cases were excellent or good,14%(5/34)were fair,and none were poor.All the fractures united 6to 8weeks after operation,a nd no fixation failure or humeral hea d necrosis was found.Conclusion Treatment of displaced humeral surg ical neck fractures with closed reduction and percutaneous pin fixation can shorten operation time,lead to minimal soft tissue lesion and reliable fixation,and allow early functional exercis e after op-eration and easy removal of the wire.
