Objective To compare the effectiveness between locking compression plate (LCP) and locked intramedullary nail (IMN) for humeral shaft fractures of types B and C. Methods Between January 2010 and January 2012, 46 patients with humeral shaft fractures of types B and C were treated, and the clinical data were retrospectively analyzed. LCP was used for internal fixation in 22 cases (LCP group), and IMN in 24 cases (IMN group). There was no significant difference in gender, age, injury causes, the side of fracture, the site of fracture, the type of fracture, associated injury, and time from injury to operation between 2 groups (P gt; 0.05). The regular clinical examination and evaluation of radiography were done. Shoulder function was evaluated by Neer grading system and elbow function was evaluated by Mayo elbow performance score after operation. Results The operation time and intraoperative blood loss in IMN group were significantly lower than those in LCP group (P lt; 0.05). There was no significant difference in hospitalization time between 2 groups (t=0.344, P=0.733). All patients were followed up 16.8 months on average (range, 12-24 months). At 6 months after operation, bone nonunion occurred in 1 patient of LCP group and in 2 patients of IMN group; the bone healing rate was 95.5% (21/22) in LCP group and 91.7% (22/24) in IMN group, showing no significant difference (χ2=0.000, P=1.000). Except for nonunion patients, the bone healing time was (11.77 ± 0.75) weeks in LCP group and (11.38 ± 0.82) weeks in IMN group, showing no significant difference (t=1.705, P=0.095). Between LCP and IMN groups, significant differences were found in radial nerve injury (4 cases vs. 0 case) and impingement of shoulder (0 case vs. 6 cases) (P lt; 0.05), but no significant difference in superficial infection (1 case vs. 0 case) and iatrogenic fracture (1 case vs. 2 cases) (P gt; 0.05). There was no significant difference in shoulder function and elbow function at 1 year after operation between 2 groups (P gt; 0.05). Conclusion LCP fixation and IMN fixation for humeral shaft fractures of types B and C can achieved satisfactory results. More attention should be paid to avoiding radial nerve injury by fixation of LCP; nail tail should be buried deeply into the cortex of the greater tuberosity and rotator cuff should be protected to decrease the rate of impingement of shoulder by fixation of IMN.
Objective To compare the effectiveness of titanium elastic nail (TEN) and locking compression plate fixation in treating femoral subtrochanteric fracture in older children. Methods Between April 2015 and September 2016, 35 older children (aged 7-13 years) with femoral subtrochanteric fractures were treated, the clinical data were retrospectively reviewed. TEN fixation was used in 19 cases (group A) and locking compression plate fixation in 16 cases (group B). There was no significant difference in age, gender, sides, fracture causes, type of fracture, and time from injury to operation between 2 groups (P>0.05). The fluoroscopy times, operation time, intraoperative blood loss, fracture healing time were recorded and compared between 2 groups. The limb function was evaluated according to the Sanders scores and Flynnet al. outcome score. Results All the patients were followed up 6-24 months (mean, 11.46 months). The operation time, intraoperative blood loss, and fracture healing time of group A were significantly less than those of group B, but the fluoroscopy times of group A was significantly more than that of group B (P<0.05). All the fractures were healed, no breakage of screw, infection of deep tissue, nerve injury, osteonecrosis of the femoral head, or other complication occurred. At last follow-up, according to the Sanders scores, the results were excellent in 14 cases, good in 4 cases, and fair in 1 case in group A with an excellent and good rate of 94.74%; the results were excellent in 12 cases, good in 3 cases, and fair in 1 case in group B with an excellent and good rate of 93.75%; showing no significant difference between 2 groups (χ2=0.400, P=0.980). According to the Flynn et al. outcome score, the results were excellent in 13 cases, good in 5 cases, and fair in 1 case in group A with an excellent and good rate of 94.74%; the results were excellent in 11 cases, good in 3 cases, and fair in 2 cases in group B with an excellent and good rate of 87.50%; showing no significant difference between 2 groups (χ2=0.748, P=0.688). Conclusion Both TEN and locking compression plate have satisfactory outcomes for treating pediatric femoral subtrochanteric fractures. TEN method has minimally trauma, security, and faster fracture healing when compared with locking compression plate.
ObjectiveTo compare the effectiveness of locking compression plate and elastic intramedullary nail for the treatment of benign long bone pathological fractures in children, so as to provide the evidence for clinical treatment. MethodsSeventy-two children with long bone pathological fractures who accorded with the inclusion criteria between January 2005 and July 2013 were randomly divided into 2 groups. Fracture was fixed with elastic intramedullary nail in 33 cases (group A) and with locking compression plate in 39 cases (group B). There was no significant difference in sex, age, body mass index, primary lesion, location of fracture, side of fracture, and interval between injury and operation between 2 groups (P>0.05). ResultsGroup A had shorter operation time, less intraoperative blood loss, and less overall costs than group B, showing significant differences (P<0.05). Primary healing of incision was obtained. All the patients were followed up 1-7 years (mean, 3.4 years). Tumor lesions disappeared and the pathological fracture healed after operation by X-ray film observation, and group A had faster fracture healing time than group B (P<0.05). There was no loosening and displacement of internal fixation, bone resorption, and bone defect nonunion in 2 groups. Recurrence was found in 2 cases (6.1%) of group A and 3 cases (7.7%) of group B, showing no significant difference (χ2=0.074, P=0.580). Re-fracture was found in 1 patient with tibial bone cyst of group B after 3 months of operation, and healed after 1 year of open reduction and internal fixation. According to X-ray film and comprehensive function evaluation of shoulder, elbow, hip, knee, and ankle, the results were all excellent in 2 groups at last follow-up. ConclusionElastic intramedullary nail fixation should be the first choice, and locking compression plate should be the second choice for children with benign long bone pathological fractures.
Objective To introduce a method for fixation in periprosthetic fracture with locking compression plate (LCP). Methods Duringthe surgery, a long 12-hole LCP was placed to the lateral side of the femur. Six holes of the plate were placed proximal to the main fracture line to make sure that there could be enough cortex units for rigid fixation of proximal fragments. Locking screws used except for the most proximal hole where a 4.5 mm screw was used instead. Results The patient was pain free at the fracture site one week after the surgery,and was able to walk with a cane 3 months after the surgery. Bone union was evident radiographically 3 months after the surgery. There was no loose signs around the stem. Six months after the surgery, the patient recovered full function without pain. Conclusion In our experience from this case, LCP in treating periprosthetic fracture was easy and less time consuming, more over, extensive periosteal stripping could be avoided. LCP is a good choice in treating some periprosthetic fractures.
Objective To summarize the cl inical appl ication of minimally invasive percutaneous locking compression plate (LCP) internal fixation in the treatment of tibial fractures and to evaluate its cl inical effects. Methods From September 2005 to September 2007, 13 patients with tibial fractures were treated with indirect reduction and minimally invasive percutaneous LCP internal fixation, 8 males and 5 females, aged 18-35 years old (27 on average). Among them, the fractures were caused by traffic accidents in 3 cases, by fall ing in 5 cases, by fall ing from height in 4 cases and by bruise in 1 case. The fractures were located at 1/3 upper tibia in 2 cases, at 1/3 medium tibia in 6 cases and at 1/3 lower tibia in 5 cases. All fracture were closed ones. According to the AO classification, 4 cases were type A, 7 type B and 2 type C. The time between fractures and operation was from 3 hours to 5 days (2.5 days on average). Results All incisions obtained heal ing by first intention. All patients were followed up for 10-18 months (13 months on average). All fractures reached cl inical heal ing, and the heal ing time was 12-20 weeks (16 weeks on average). There was no delayed fracture heal ing, nonunion, infection and internal fixation failure. No compl ications such as rotation, crispatura deformity and internal fixation loosening were found. According to the HSS scoring, the function of the knee joint was graded 85-95 (90 on average), and the range of motion was 100-130° (120° on average). According to the AOFAS Ankie Hindfoot Scoring, the function of the ankle joint was graded 80-95 (92.4 on average). Nine cases were excellent, 4 good, and the choiceness rate was 100%. Conclusion Minimally invasive percutaneous LCP internal fixation is in accord with biological set principles and beneficial for tibial fracture heal ing and reconstruction of soft tissues.
