Objective To evaluate the effectiveness of bridging fixation with long locking plate for displaced midshaft clavicular fractures. Methods Between October 2010 and December 2011, 18 patients with displaced midshaft clavicular fracture were treated with reduction and bridging fixation with 9 or 10 holes locking plate. There were 17 males and 1 female with an average age of 47 years (range, 23-82 years). Fracture was caused by traffic accident in 6 cases, by falling in 10 cases, by crushing in 1 case, and by crashing object in 1 case. All fractures were closed and displaced or shortened (range, 2.1-3.4 cm; mean, 2.62 cm) with angulation deformity. According to Robinson classification criteria, 5 cases were rated as type 2B1 and 13 as type 2B2. The duration from injury to surgery was 5 hours to 19 days (mean, 5 days). The fracture healing time and complication were recorded; the effectiveness evaluation was performed with Constant-Murley score and satisfaction to appearance. Results No neurologic or vascular complication occurred with primary healing of incision. All patients were followed up 12-22 months (mean, 14.7 months). The fracture healing time was 9-14 weeks (mean, 11.4 weeks). During follow-up, no loosening or breakage of internal fixator was observed. The Constant-Murley score was 82-98 (mean, 92.4) at last follow-up; the satisfaction rate of appearance was 88.9% (16/18). Conclusion Bridging fixation with long locking plate is an effective method for treatment of displaced midshaft clavicular fractures. Preserved blood supply and stable angle are important to fracture healing.
Objective To analyse the procedure and effectiveness of internal fixation in treatment of displaced radial head fractures. Methods Between August 2005 and May 2009, 35 patients with displaced radial head fractures underwent open reduction and internal fixation with SmartNail® and/or AO mini-plates. There were 28 males and 7 females with an average age of 28.4 years (range, 17-48 years). The injury mechanism included traffic accident in 16 patients, falling in 13, and falling from height in 6. According to Mason classification, 21 fractures were rated as type II, 9 as type III, and 5 as type IV. All fracturs were closed fractures. Six cases complicated by radial neck fractures, 1 case by olecranon fracture, 3 by posterior dislocations of the elbow, 1 by posterior dislocation of the elbow and coronoid process fracture, and 3 by medial collateral ligament injuries. The time from injury to operation was 3 to 7 days. Results Except 1 patient whose incision healed by second intention, healing of incision by first intention was achieved in the other patients. All patients were followed up 12-25 months with an average of 17 months. The average fracture healing time was 10.2 weeks (range, 8-16 weeks). At last follow-up, the average flexion and extension of the elbow was 119° (range, 95-145°). The average arc of forearm rotation was 126° (range, 90-175°). According to elbow functional evaluation criteria by Broberg and Morrey, the results were excellent in 18 cases, good in 13, and fair in 4; the excellent and good rate was 88.6%. Conclusion In treatment of displaced radial head fractures, open reduction and internal fixation can be performed with SmartNail® and/or AO mini-plates based on different fracture types and the short-term effectiveness is satisfactory.
Objective To compare the effectiveness of internal fixation, hemiarthroplasty, and total hip arthroplasty in the treatment of displaced femoral neck fractures in elderly patients so as to provide the evidence for the selection of therapeutic methods. Methods Between May 2005 and April 2008, 108 elderly patients with displaced femoral neck fractures were treated by internal fixation with compression screw (IF group, n=31), hemiarthroplasty (HA group, n=37), and total hiparthroplasty (THA group, n=40). In IF group, there were 8 males and 23 females with an average age of 73 years (range, 65-80 years); fractures were caused by tumbl ing (25 cases) and traffic accident (6 cases), including 17 cases of Garden type III and 14 cases of Garden type IV; and the time from injury to operation ranged from 8 hours to 13 days with an average of 4.2 days. In HA group, there were 10 males and 27 females with an average age of 74 years (range, 65-80 years); fractures were caused by tumbl ing (29 cases) and traffic accident (8 cases), including 21 cases of Garden type III and 16 cases of Garden type IV; and the time from injury to operation ranged from 1 to 14 days with an average of 4.4 days. In THA group, there were 11 males and 29 females with an average age of 73 years (range, 66-80 years); fractures were caused by tumbl ing (32 cases) and traffic accident (8 cases), including 23 cases of Garden type III and 17 cases of Garden type IV; and the time from injury to operation ranged from 2 to 14 days with an average of 5.6 days. There was no significant difference in general data among 3 groups (P gt; 0.05). Results There were significant differences in operation time and blood loss among 3 groups (P lt; 0.05), and IF group was less than other 2 groups. All patients were followed up 1 year and 4 months to 2 years and 3 months with an average of 1 year and 8 months. In IF group, HA group, and THA group, the rates of early postoperative compl ications were 19.4% (6/31), 8.1% (3/37), and 7.5% (3/40), respectively; the rates of late postoperative compl ications were 29.0% (9/31), 13.5% (5/37), and 7.5% (3/40), respectively; and the reoperation rates were 29.0% (9/31), 10.8% (4/37), and 5.0% (2/40), respectively. The rates of the early postoperative compl ication, late postoperative compl ication, and reoperation rate were significantly higher in IF group than in HA group and THA group (P lt; 0.05), but there was no significant difference between HA group and THA group (P gt; 0.05). The mortal ity rates were 16.1% (5/31), 13.5% (5/37), and 15.0% (6/40) in IF group, HA group, and THA group, respectively; showing no significant difference (P gt; 0.05). According to Harris hip score, the excellent and good rates were 65.4% (17/26), 81.3% (26/32), and 85.3% (29/34) in IF group, HA group, and THA group, respectively; showing significant differences among 3 groups (P lt; 0.05). Conclusion According to patient’s age, l ife expectancy, and general conditions, THA is a reasonable choice for the patients aged 65-80 years with displaced femoral neck fracture.
Objective To compare the therapeutic effect of cannulated screws fixation at different time points through different reduction methods on the heal ing of displaced femoral neck fractures. Methods From January 1997 to September 2007, 240 patients with displaced femoral neck fracture were treated, including 121 males and 119 females aged 22-79 years old (average 56 years old). All cases were fresh and close fractures. According to the fractured part, there were 133cases of subcapital fracture, 64 of transcervical fracture and 43 of basal fracture. According to Garden classification, there were 105 cases of type III and 135 of type IV. Cannulated screws fixation was performed on all the patients, and the time from injury to operation was 6 hours to 7 days. Fifty-five cases received closed reduction and 59 cases received l imited open reduction as emergency treatment, while 65 cases received closed reduction and 61 cases received l imited open reduction as selective operation. Different groups were compared in terms of the heal ing rate of fracture, the excellent and good rate of reduction as well as the excellent and good rate of fixation. Results There was no significant difference between the closed reduction and the l imited open reduction in terms of operation time and bleeding volume (P gt; 0.05). Postoperatively, all wounds healed by first intention, no infection was observed, avascular necrosis of femoral head occurred in 44 cases, and the rate of avascular necrosis of femoral head in the l imited open reduction at emergency group was less than that of other 3 groups (P lt; 0.01). All the patients were followed up for 12-72 months (average 38 months), 193 cases got fracture heal ing at 10-23 months after operation (average 14 months). For the closed reduction as emergency operation group, the l imited open reduction as emergency operation group, the closed reduction as selective operation group, and the l imited open reduction as selective operation group, the heal ing rate of fracture was 74.55%, 91.53%, 69.23% and 86.89%, respectively; the excellent and good rate of reduction was 73.73%, 94.92%,70.77% and 91.80%, respectively; the excellent and good rate of fixation was 76.36%, 93.22%, 73.85% and 88.52%, respectively. The heal ing rate of fracture, the excellent and good rate of reduction as well as the excellent and good rate of fixation in the l imited open groups were higher than that of the closed reduction groups (Plt; 0.01), and there was no significant difference between the emergency operation groups and the selective operational groups (Pgt; 0.05). Conclusion The reduction methods have significant influences on the heal ing of fractures after cannulated screws fixation of the displaced femoral neck fracture, and the operation time has no obvious effect on fracture heal ing.
Objective To compare the effects of operative versus nonoperative treatment for displaced intra-articular calcaneal fractures. Methods All randomized controlled trials (RCTs) of operative versus nonoperative treatment for displaced intra-articular calcaneal fractures were identified. Quality assessment and data extraction were performed by two reviewers independently. Results Four published trials involving 530 patients were included. All studies compared operative with nonoperative treatment. It was clear that operative treatment was superior to nonoperative treatment in terms of helping patients back to work, reducing problems wearing shoes, expanding the range of motion of subtalar joint, and improving the recovery of Bohler’s angle. As for foot pain, there was no difference between the two methods. Because the outcome measures varied across the trials, a meta-analysis could not be performed. Conclusions Both operative and nonoperative treatments produce comparable long-term outcomes in the treatment of displaced intra-articular calcaneal fractures. Because of the poor reporting of outcomes, it is not possible to determine if there is any significant difference in outcome measures apart from those listed above. More trials with high methodological quality are needed.
ObjectiveTo discuss the effectiveness of Poking reduction with shoulder arthroscopy-assisted surgery for displaced scapular neck fracture. MethodsBetween January 2009 and January 2012,9 cases of displaced scapular neck fracture underwent shoulder arthroscopy-assisted surgery for Poking reduction treatment.Of 9 cases,6 were men,and 3 were women,aged 21-54 years (mean,39 years).The causes were traffic accident injury in 7 cases,falling injury from height in 1 case,and hurt injury in 1 case.The shoulder abduction,flexion,and external rotation were obviously limited.X-ray films showed all cases had obvious displaced scapular neck fracture.Three-dimensional reconstruction of CT showed a grossly displaced of fracture.The time of injury to surgery was 4-27 days (mean,11 days). ResultsPatients obtained healing of incision by first intension,without infection,neurovascular injury,or other surgery-related complications.All patients were followed up 19-31 months (mean,23 months).X-ray films showed scapular neck fractures healed from 7 to 11 weeks (mean,8 weeks).At last follow-up,the shoulder abduction,flexion,and external rotation activity were improved significantly when compared with ones at preoperation (P<0.05);the shoulder Constant score,American Shoulder and Elbow Surgenos (ASES) score,and Rowe score were significantly better than preoperative scores (P<0.05). ConclusionThe reduction of displaced scapular neck fracture is necessary,and arthroscopic Poking reduction and fixation for displaced scapular neck fracture can reconstruct the shoulder stability and reduce complications
ObjectiveTo compare the effectiveness of percutaneous compression plate (PCCP) and hollow compression screw in the treatment of displaced femoral neck fractures. MethodsBetween January 2010 and June 2014, 70 patients with displaced femoral neck fractures were randomly divided into 2 groups. After reduction, fracture was fixed with PCCP in 35 cases (group A) and with hollow compression screw in 35 cases (group B). There was no significant difference in the gender, age, cause, side and type of fractures, time from injury to operation, associated disease, pre-operative Harris score and visual analogue scale (VAS) score between 2 groups (P > 0.05). The operation time, intra-operative blood loss, fracture healing time, fracture reduction quality, time of rehabilitation and weightloading; complication, post-operative Harris score and post-operative VAS score were compared between 2 groups. ResultsThe incisions healed by first intention. All patients were followed up 13-34 months (mean, 23.7 months). There were significant differences in operation time, intra-operative blood loss, and fracture healing time between 2 groups (P < 0.05). There was no significant in the fracture reduction quality between 2 groups (P > 0.05). Avascular necrosis of the femoral head occurred in 2 cases of group A after operation (fracture reduction quality: grade IV); and avascular necrosis of the femoral head occurred in 4 cases of group B after operation (fracture reduction quality: grade I in 2 cases, grade Ⅱ in 1 case, grade Ⅲ in 1 case, and grade IV in 1 case), nonunion in 1 case, and screw loosening in 3 cases; and there was significant difference in the incidence of bone nonunion and avascular necrosis of the femoral head between 2 groups (χ2=-3.997, P=0.046). Difference was significant in fracture reduction quality in the patients with avascular necrosis of the femoral head and nonunion between 2 groups (χ2=1.991, P=0.047). The time of rehabilitation and weight-loading of group A was significantly earlier than that of group B (P < 0.05); the Harris and VAS scores of group A were significantly better than those of group B at 12 months after operation (P < 0.05). ConclusionPCCP for treatment of displaced femoral neck fractures has better static stability and better sliding dynamic pressure effect than hollow compression screw, and it can provide earlier rehabilitation and weight-loading postoperatively and obviously decrease the incidence of bone nonunion and avascular necrosis of the femoral head, but avascular necrosis of the femoral head still occur in patients with poor reduction or comminuted fracture.
Objective To compare the short-term clinical outcomes of secondary total hip arthroplasty (THA) after failure of internal fixation with primary THA in elderly patients with displaced femoral neck fractures, and explore the best treatment for displaced femoral neck fractures in the elderly. Methods A total of 300 elderly patients with displaced femoral neck fractures from January 2011 to January 2015 were retrospectively enrolled in this study, of whom 150 underwent primary THA and 150 underwent secondary THA after failure of internal fixation. The operation time, intraoperative bleeding volume, postoperative drainage volume, postoperative ambulation time, length of postoperative hospitalization, incidence of postoperative complications, and score of postoperative hip joint function were compared between the two groups. Results Compared with those in the secondary THA group, in the primary THA group, the operation time was shorter [(54.7±15.3) vs. (70.1±23.4) minutes], the intraoperative bleeding volume was less [(116.9±35.0) vs. (131.7±44.5) mL], the postoperative ambulation was earlier [(1.0±0.3) vs. (1.8±0.6) days], the length of postoperative hospitalization was shorter [(12.0±2.9) vs. (15.2±3.1) days], and the differences were all statistically significant (P<0.05); but there was no statistically significant difference in the incidence of postoperative complications or the Harris scores at 3, 6, 12, and 24 months after operation (P>0.05). Conclusion The secondary THA for femoral neck fracture is more difficult, with longer stay in hospital, but the short-term clinical efficacy is similar to that of the primary THA.
