Abstract：

Objective To investigate the clinical effects of Gamma nails in treatment of intertroehanteric fractures.Methods From October 2000 to December 2006,we used Gamma nails to treat 367 patients with intertrochanteric fractures.They were 135 males and 232 females,aged from 20 to 103years(average,73.1 years).Low-impact injury was found in 309 patients and high-velocity injury in 58patients.By AO classification,there were 117 cases of type A1,208 cases of type A2 and 42 cases of type A3.The period from injury to operation was 4.7 days on average,ranging from 1 to 17 days.The postoperative hip radiographs and the patient's satisfaction were evaluated.The Harris hip score(HHS)self-report was used to compare hip functions before fracture and at the last follow-up. Results Of all the patients,331were followed up for 4 to106 months(mean,16.1 months).On average,99.7%of the fractures(330 cases)healed in 14.2 weeks(range,12 to 24 weeks).Postoperative complications occurred in 28 cases.The average HHS before fracture was 84.6±10.0 points(range,31 to 90),which significantly decreased at the finial follow-up to 75.8±12.8 points(range,19 to 90)(t=6.510,P=0.000).63.7%(135/212)of the patients rated the treatment outcome as excellent,31.6%(67/212)as good,2.8%(6/212)as fair,and 1.9%(4/212)as poor.51.4%(109/212)of the patients felt more or less pain in the hip. Conclusions Gamma nails are effective in treatment of intertroehanteric fractures.However,as the postoperative local pain is evident and the postoperative hip function decreases obviously,this operation needs to be improved.     

股骨干骨折合并同侧股骨颈骨折手术方法的选择及疗效分析

Objective To investigate clinical features,operative treatments and outcomes of ipsilateral fractures of femoral shaft and neck. Methods Forty-two cases of ipsilateral fractures of femoral neck and shaft were treated from November,2004 to November,2009 in our institution.They were 37 males and 5 females.Their ages ranged from 21 to 84 years,with an average of 59.2 years.The fracture involved 18upper shafts,17 middle shafts and 7 lower shafts.By Garden classification,there were 5 cases of type Ⅰ,10cases of type Ⅱ,21 cases of type Ⅲ,and 6 cases of type Ⅳ neck fractures.All cases were diagnosed in 3days after admission;there were no misdiagnosis or missed diagnosis.Twenty patients were treated by artificialjoint replacement(replacement group),while 22 patients by fixation with cannulated nails,intramedullary nails,or plate(fixation group).Outcomes were compared between the 2 groups. Results All cases were followed up for 1 to 3 years,with an average of 2 years.Femoral neck fractures united between 12 to 20weeks,with an average of 16 weeks;femoral shaft fractures united between 14 to 24 weeks,with an average of 18 weeks.There were significant differences between the 2 groups in average length of hospital stay,ambulation time,blood loss,postoperative activities and good to excellent rate of postoperative joint function(P<0.05).There were no significant differences between the 2 groups in the Merchan scores 1,2,and 3 years after operation for complication-free patients(P>0.05). Conclusion Surgical treatment of ipsilateral fractures of femoral neck and shaft depends on position of the shaft fracture,displacement of the neck fracture,physical constitution and age of the patient to be treated.     

Comparative study of anterolateral approach versus posterior approach for total hip replacement in the treatment of femoral neck fractures in elderly patients

Objective： To compare the clinical outcome of anterolateral minimally invasive approach versus conventional posterior approach for total hip replacement against femoral neck fractures in elderly patients.
Methods： The retrospective study was carried out on 42 patients who suffered from displaced femoral neck fractures （19 cases of Garden type Ⅲ, 23 cases of Garden type Ⅳ） treated by total hip replacement via anterolateral minimally invasive approach or conventional posterior approach by the same experienced surgeon. The average age of the patients was 78.1 years （range： 65-89 years）. They were divided into anterolateral mini-invasive group （22 cases） and posterior group （20 cases）. The mean time of follow-up was 13 months （range： 6-36 months）. The anterolateral approach described by Hardinge goes through between anterior 1/3 and posterior 2/3 of the gluteus medius muscle, reaching the femoral neck from anterior capsule. The traditional posterior approach described by Moore （Southern incision） goes through the insertions of short external rotation muscles, reaching the femoral neck from posterior capsule. The related variables under observation were length of incision, operation time, postoperative limp, length of hospital stay and bed stay and dislolcation rate.
Results： The length of the skin incision varied between 7 cm and 12 cm with the anterolateral minimally invasive technique, compared to 15-22 cm in the conventional procedure. It took less time （average 15 minutes） to complete the anterolateral minimally invasive approach （72 15 min）, compared with the conventional approach （87 min ±10 min）. The average Harris hip score was 91.23±10.20 in anterolateral approach, 90.03±11.05 in the posterior approach. The average length of hospital stay for patients with the anterolateral approach was （6.4±2.2） days （range： 4-9 days）, while that in posterior approach was （9.2 ±3.1） days （range： 6-13 days）. The average length of bed stay was （3.4±1.1） days （range： 2-5 days） in anterolateral group and （6.2±2.8） days （range： 3-10 days） in posterior group. No patients in anterolateral group experienced dislocation. One （5%） hip in posterior approach had dislocation. Conclusions： Anterolateral mini-invasive approach can decrease trauma, operation time, length of hospital stay and bed stay and rehabilitation time. The stability and minimal muscular damage permit the acceleration of postoperative rehabilitation, which can subsequently reduce the perioperative risk in the treatment of femoral neck fractures in the elderly undergoing total hip replacement.     

儿童胫骨结节骨骺骨折

Objective To discuss the characteristics, treatment method and prognosis of tibial tuberosity avulsion fracture in children. Methods From January 1995 to December 2007, there were 25 cases (23 boys and 2 girls). The age at injury ranged from 12 to 16 years(average 13.5 years). All cases were unilateral involved (10 of left, 15 of right). All of the injuries resulted from participation in athletic activities, 10 in basketball, 7 while jumping, and 8 in football game. According to the classification of Ogden, there were 1 type 1A, 4 type 1B, 5 type 2A, 7 type 2B, 4 type 3A, and 4 type 3B fractures. One type 1A fracture was treated nonoperatively with east immobilization, and other 24 fractures with open reduction and internal fixation. Results All of 25 cases were followed from 14 months to 7 years (average 43 months). The range of motion of knee joint was 0°-140° 3 months after operation, and all of them recovered to pre-injury levels of activity by 6 months after operation. According to Mosier clinical assessment system, the final outcome was evaluated as excellent in all. Wound healed primary, no compartment syndrome was found. The time of bony union ranged from 2 to 5 months, with the mean time of 3 months. No complications of infection, ex-tremities deformity and inner fixation failure were found. Conclusion The tuberosity avulsion fracture in children is an uncommon and special type of epiphyseal injury. These fractures occur in the narrow range of 13 to 16 years of age. The majority of patients are males, and most of them are unilateral involved. This in-jury has an excellent outcome without deformity or functional loss, once adequate reduction and fixation of fracture fragments have been achieved.

肱骨远端解剖型锁定接骨板的初步应用

Objective To investigate surgical techniques and effects of AO distal humeral plate used as a treatment alternative for distal humerus fractures. Methods From April 2008 to July 2009, 22 cases of distal humerus fracture were treated with open reduction and internal fixation with AO distal humeral plate (DHP). They were 10 males and 12 females. Their ages ranged from 14 to 65 years (average, 40 years). According to AO classification, one case was Type A, 6 were Type B and 15 were Type C. Their elbows were not immobilized postoperatively. The mean follow-up was 15 months. Functional results were evaluated according to the Mayo elbow performance score (MEPS). Results Fractures healed in all cases. There was no hardware failure or loss of reduction. No patient complained of pain. They had an average elbow flexion of 108° (range, 60° to 130°) and an average full extension to 25° (range 0 to 80°) . The average ulnohumeral motion was 79° (range, 10° to 130°). The average MEPS was 91 points (range, 60 to 100 points). Fifteen cases scored excellent, 5 good and 2 fair. Conclusions DHP has advantages of an anatomically preshaped locking plate which may enhance anchorage in fractures difficult to manage, such as metaphyseal comminuted supra-intercondylar fractures, lower fractures with relatively small distal fragments and osteoporotic fractures, and allow early postoperative rehabilitation. However, in order to achieve an optimal result,precise location and pre-bending of the plate should be ensured.
