Objective To explore the classification and surgical treatment of scapular neck frac-tures. Methods A retrospective analysis was done based on the clinical data of 18 patients (including 12 males and 6 females) who accepted operation in Tianjin Hospital from January 2000 to December 2007. The average age of the patients was 41 years (17-62 years). All patients accepted CT examina-tion. According to Hardegger classification, there were 10 patients with anatomical neck fractures and eight with surgical neck fractures. According to Miller system, there were five patients with type II A fractures, six with type II B fractures, six with type II C fractures and one with type II B + IIC fracture. Of all, 15 patients had associated injury. The operative approach included posterolateral approach in nine patients, modified Judet approach in six and anteroposterior conjoint approach in three. Reconstruction plates and lag screws were applied to fix the fractures. Results All patients were followed up consecu-tively with an average period of 25. 5 months (6-70 months). The mean Constant-Murley score was 73 points (35-95 points, meadian 75.5 points) after treatment. There were two patients with malreduction,one with shoulder instability and three with traumatic arthritis postoperatively. Conclusions The indi-cations for early operation include: (1) angular deformity in horizontal or coronal planes of fractures, ie,glenopolar angle (GPA) <20°(2) fracture displacement =10 mm;(3) associated with floating shoul-der injury or superior suspensory shoulder complex injury. The major factors influencing prognosis are as-sociated injuries, quality of fractures reduction, fixation stability, injury of rotator cuff and postoperative rehabilitation.

Objectve The purpose of the study was to evaluate the surgical treatment method and outcomes of capitellar fractures. Methods From December 2004 to December 2006, sixteen patients with a capitellar fracture were included in the study. There were eight males and eight females. According to Bryan and Morrey classification, there were eight type Ⅰ fractures, one type Ⅲ fracture and seven type Ⅳ fractures. In three of type Ⅳ, a separate trochlear fracture fragment with impaction was seen. Distal lateral column posteroinferior metaphyseal comminutiou and/or impaction was observed in association with three fractures including two type Ⅳ fractures and one type Ⅲ fracture. One Mason type Ⅰ radial head fracture occurred in association with an ipsilateral type Ⅳ capiteilum fracture. The patients ranged from sixteen to sixty-five years old, with an average age of 44.9 years. An extensile lateral exposure and articular fixation with cannu-lated compression screws were performed within five days of injury. Clinical, radiographic, and functional el-bow index rating scale of Broberg-Money were evaluated retrospectively. Results The follow-up time ranged from 24 to 36 months,with the mean of 29 months. All fractures healed at an average of 7.9 (range, 6 to 11) weeks without radiographic evidence of osteonecrosis of the fracture fragment. Average arc of motion was 125.8°±16.8° in flexion-extension and 163.1°±10.62° in pronation-supination. The mean Broberg-Mor-rey was 92.0 points, with eight excellent results, seven good results, and one poor result. There were one pa-tient with a minimum of grade 1 radio-capitellar arthrosis.Fifteen of the sixteen adults were able to continue their former professional activities. The patient had persistent postoperative stiffness with a flexion contrac-ture at the last postoperative visit. Conclusion Prompt treatment with anatomic reduction and internal fixa-tion with lag screws followed by early rehabilitation can lead to functional arc and satisfactory outcome.

Objective To investigate surgical outcomes of anterolateral plus posteromedial approaches for treatment of complex tibial plateau fractures.Methods We reviewed 68 patients with tibial plateau fractures of Schatzker types Ⅴ and Ⅵ who had been treated from January 2008 to December 2011 and fully followed up in our department.They were 42 men and 26 women,22 to 64 years of age (average,42.3 years).Fractures occurred at the left side in 24 cases and at the right side in 44 cases.Intervals between injury and operation ranged from 3 to 15 days,7.4 days on average.All of them were operated on through anterolateral plus posteromedial approaches.T-or L-shaped steel plates were used laterally while reconstruction plates or T-shaped plates for distal radius were used medially.Results In this cohort the operation time averaged 3.13 hours,intraoperative blood loss 562.7 mL and hospital stay 20.4 days.All cases were followed up for an average of 18.8 months (range,12 to 38 months).Fractures healed from 4 to 8 months,6.7 months on average.The average tibial plateau angle,posterior slope angle and femorotibial angle immediately postoperation were respectively 87.3°± 1.5°,12.0°± 2.5° and 170.0°± 2.5°,not significantly different from those at one year postoperation (86.8° ± 1.2°,13.0° ± 1.8° and 171.0° ± 1.7°) (P ＞ 0.05).According to The Hospital for Special Surgery Score,the outcomes were excellent in 36 cases,good in 24 cases,fair in 6 cases and poor in 2 cases,with a good to excellent rate of 88.2％.No neural or vascular injury,deep infection,or implant failure was found in this group.Conclusion Anterolateral plus posteromedial approaches are effective for complex tibial plateau fractures,leading to anatomic reduction,stable fixation and early functional rehabilitation.

[Objective]To analysis the factors influencing the results and complications of displaced intra-articular calcaneal fractures treated with open reduction and internal fixation or sledging.[Method]Twenty-seven cases,29 displaced intra-articular calcaneal fractures treated with open reduction and internal fixation or sledging were reviewed and followed with 7～60 months.The postoperative results were evaluated with AOFAS.[Result]The scores were between 53 and 100 with average 87.2,with good results.The functional results of Sanders Ⅲ and Ⅳ fractures were worse than type Ⅱ fracures.[Conclusion]The patients with displaced intra-articular calcaneal fractures should be treated with operation.With less invasive manipulation,extensive lateral L incision hasn't more relation to infection.The degree of initial injury and the operative quality are important factors influencing prognosis.

[Objective]To observe the clinical effects and the comments of the circular external fixator on the treatment of spiral and oblique fractures of distal one-third of tibia-fibular.[Method]Fifteen patients(11 males,4 females),with a mean age of 38.5 years(range 21 to 57)with spiral and oblique fractures of distal 1/3 of tibia-fibular were treated with circular external fixator from August 2005 to October 2008.The aetiologies of the fractures were as follows:8 cases,motor vehicle accident;5 cases,falls;2 cases,crush.All the fractures were closed.Nine cases had skin and soft tissue contusion on the distal leg and ankle.[Result]All patients were followed up and acquired the bony union.The mean follow-up time was 10.5 months(range 6～30 months).The mean framing time was 4.5 months(range 2.5～9 months).None of the patients had soft tissues infection and osteomyelitis.None of the patients suffered from the complications such as shortness,angulation,rotation deformity.None of the patients suffered from refracture after removal of the frame.Three patients had pin tract infection and were treated by oral antibiotics.Four patients had loss of range of motion in the ankle after the removal of the frame.These 4 patients had loss of mean 5-degree dorsiflexion and mean 10-degree plantar-flexion.All the patients had full knee function.[Conclusion]The circular external fixator may be used as an alternative method in the treatment of spiral and oblique fractures of distal 1/3 of tibia-fibular and the patients can avoid suffering from the removal of internal fixators.

[Objective]To investigate the clinical effects of Ilizarov external fixator combined pedicle flaps transfer on the treatment of infective fracture nonunion with soft tissue defects in legs.[Method]Fiftecn patients aged 20-58 years(mean age 40 years) were treated with Ilizarov external fixator combined pedicle flaps transfer from July 2005 to September 2008.The areas of flaps were 6 cm?5 cm-15 cm?10 cm.[Result]All patients were followed up.The mean follow-up time was 13 months(range 8-33 months).Fourteen patients achieved fracture union.One patient had partial flap necrosis and recurrent infection and healed aafter a repeat operation.The average tibia fracture healing time was 6.5 months.The mean framing time was 7.0 months.[Conclusion]Ilizarov external fixator combined pedicle flaps transfer can effectively treat infective fractures nonunion with soft tissue defects in legs.In order to achieve the desired results,proper surgery timing and surgical indications are important.

[Objective]To analize the complications in the treatment of the fractures around the knee joint with less invasive stabilization system(LISS).[Method]From July 2005 to October 2007,89 patients with 91 fractures around knee joint were treated with the LISS,including 45 fractures of distal femur and 46 fractures of proximal tibia.[Result]All patients were followed up for 13 to 29 months.The average time to union was 16 weeks(ranged,11-25 weeks).The functional outcome: 45 had an excellent result,35 had a good result and 11 had a fair result,with 87.9% excellent to good results.There were 10 patients(11%) with symptomatic hardware irritation,2 of them had soft-tissue disruption.Seven cases(8%) had malalignment,2(2%) loss of reduction,1(1%) delayed union,1(1%) failed fixation,1 superficial peroneal nerve injury and 1 profound peroneal nerve injury.Cold-welding occurred in 9 cases(10%) which resulted in difficult removal.[Conclusion]LISS is one of the reliable and effective methods in fixation of the fractures around the knee joint.However,its operation indications and operating instructions should be strictly followed.
