  • ELASTIC STABLE INTRAMEDULLARY NAILING FOR TREATMENT OF BENIGN LESIONS OF HUMERUS COMPLICATING BY PATHOLOGICAL FRACTURE IN CHILDREN

    Objective To exploere the effectiveness and advantages of elastic stable intramedullary nail (ESIN) combined with curettage and graft for the treatment of benign lesions of humerus complicating by pathological fracture in children. Methods ESIN internal fixation combined with curettage and graft was used to treat benign lesions of the humerus complicating by pathological fracture in 11 children patients between January 2007 and January 2011. Of 11 patients, 7 were boy and 4 were girl, aged from 5 to 14 years (mean, 9.4 years). The disease duration ranged from 2 to 14 days (mean, 6 days). All fractures were closed fracture, which locations were the proximal humerus in 6 cases, the humeral shaft in 4 cases, and the distal humerus in 1 case; benign lesions of the humerus included aneurysmal bone cyst in 1 case, simple bone cyst in 7 cases, and fibrous dysplasia in 3 cases. Based on imaging studies, preoperative diagnosis was almost clear. The time from hospitalization to operation was 3-5 days Results Healing of incision by first intention was obtained in all cases, with no infection. The mean follow-up was 25.6 months (range, 12-36 months). All patients achieved pain relief at 6 weeks postoperatively and fractures healed completely at 3 to 4 months after operation (mean, 3.3 months). No recurrence or re-fracture was observed during follow-up. The ESIN was removed at 10-14 months after operation (mean, 12.5 months). The lesion disappeared completely in 8 cases and partially in 3 cases. No pain of affected limb or motion limitation of shoulder and elbows was observed. One patient had limb shortening of 2 cm at last follow-up, but he had no function problem. According to Neer shoulder and Mayo elbow function scores, the results were excellent in 11 cases. Conclusion It is a good method to treat benign lesions of the humerus complicating by pathological fracture in children to use ESIN internal fixation combined with curettage and graft. After only a single operation intervention, it can provide early mechanical stability and rapid fracture healing and allow early rehabilitation exercise.

  • Lateral decubitus position assisted plate internal fixation through a lateral incision to assist reduction combined with intramedullary nail in treatment of complicated subtrochanteric femoral fracture

    Objective To investigate the effectiveness of lateral decubitus position assisted plate internal fixation through a lateral incision to assist reduction combined with intramedullary nail in the treatment of complicated subtrochanteric femoral fracture. Methods The clinical data of 16 patients with complicated subtrochanteric femoral fractures (Seinsheimer type Ⅲ-Ⅴ) treated with lateral decubitus position assisted plate internal fixation through a lateral incision to assist reduction combined with intramedullary nail between September 2017 and August 2020 were retrospectively analyzed. There were 13 males and 3 females with an average age of 47 years (range, 26-85 years). There were 12 cases of high-energy injury and 4 cases of low-energy injury. According to Seinsheimer classification, there were 3 cases of type ⅢA, 2 cases of type ⅢB, 7 cases of type Ⅳ, and 4 cases of type Ⅴ. The time from injury to operation ranged from 2 to 6 days, with an average of 4.7 days. The operation time, intraoperative blood loss, postoperative drainage volume, hospitalization stay, surgical complications, fracture healing time, and collodiaphyseal angle of the affected and healthy sides before and after operation were recorded. Hip fracture Harris score was used to evaluate hip function. Results The operation time was 90-180 minutes (mean, 135.9 minutes), the intraoperative blood loss was 200-400 mL (mean, 288.8 mL), the postoperative drainage volume was 120-220 mL (mean, 140.0 mL), and the hospitalization stay was 12-22 days (mean, 15.8 days). All the 16 patients were followed up 9-12 months (mean, 9.9 months). There was 1 case of incision superficial infection after operation, which healed after anti-infection treatment; no complication such as deep venous thrombosis of lower limbs, coxa vara deformity, re-fracture, or broken nails occurred. All the fractures healed successfully, the healing time ranged from 12 to 20 weeks, with an average of 17.5 weeks. At 6 months after operation, the Harris score was 87-96, with an average of 91.5; the results were excellent in 11 cases and good in 5 cases, with the excellent and good rate of 100%. The collodiaphyseal angle of the affected side was (124.0±5.7)°, while that of the healthy side was (132.0±2.1)°, showing significant difference between the two sides (t=–7.376, P=0.001). At last follow-up, the collodiaphyseal angle of the affected side was (129.0±3.2)°, which significantly improved when compared with that before operation (t=–6.175, P=0.002), and there was no significant difference between the affected side and the healthy side (t=–2.648, P=0.181). ConclusionLateral decubitus position assisted plate internal fixation through a lateral incision to assist reduction combined with intramedullary nail is a reliable internal fixation method for the treatment of complicated subtrochanteric femoral fractures. The use of plate reduction is conducive to maintaining the force line of the femoral trochanter. The enlargement of the incision is conducive to the accurate implantation of intramedullary nails without affecting fracture healing.

  • EFFECT OF BLOCKING SCREWS ON BREAKAGE OF INTERLOCKING INTRAMEDULLARY NAILS

    Objective To explore the effect of blocking screws on the breakage of interlocking intramedullary nails. Methods From January 2003to August 2005, 56 patients with fresh and close fracture of long shafts were treated by interlocking intramedullary nails. Among them, there were 32 males and 24 females, including 26 femoral fracture and 30 tibial fracture. Fracture of femoral and tibialshaft was fixed with interlocking intramedullary nails normally in group Ⅰ(n=32). And long oblique, spiral, proximal or distal fracture of bone shaft was fixed with interlocking intramedullary nails and blocking screws in group Ⅱ(n=24). Results All cases were followed up 12 to 21 months(16 months on average). In group Ⅰ, fracture healing failed and the intramedullary nails broke in 3 cases, breakage site was the middle femoral fracture area in 1 case and the first distal interlocking nail hole in 2 cases of distal 1/3 tibial fracture. Fractures healed 6 to 12 months after operations in the other cases, but more bony callus occurred in fracture area. In group Ⅱ, fractures healing and good alignment were achieved, and no breakage was found in all 24cases. Conclusion The use of blocking screws added to interlocking intramedullary nails could improve the stability of fracture areas distinctively, and hence reduce the breakage of intramedullary nails.

    ObjectiveTo explore the effectiveness difference between titanium elastic intramedullary nail internal fixation and bone plate internal fixation in the treatment of adult Galeazzi fracture.MethodsNinety-seven patients of Galeazzi fracture according with the selection criteria were divided into 2 groups by prospective cohort study, who were admitted between January 2012 and November 2015. In the patients, 59 were treated with open reduction and bone plate internal fixation (plate group), and 38 with titanium elastic intramedullary nail internal fixation (minimally invasive group). There was no significant difference in the gender, age, cause of injury, fracture site, type of fracture, and time from injury to operation between 2 groups (P>0.05). The operation time, intraoperative blood loss, fracture healing time, and complications were recorded and compared between 2 groups, and the forearm function was evaluated by Anderson score.ResultsAll the patients were followed up 12-23 months (mean, 17 months). The operation time, intraoperative blood loss, fracture healing time of minimally invasive group were significantly less than those in plate group (P<0.05). There were 1 case of fracture nonunion, 1 case of wound infection in plate group, and 1 case of nail tail slight infection in minimally invasive group, which were all cured after the corresponding treatment. The remaining patients had good fracture healing, and no vascular injury, internal fixation failure, deep infection, or other complications occurred. According to Anderson score at 12 months after operation, the forearm function results were excellent in 46 cases, good in 12 cases, and poor in 1 case, with an excellent and good rate of 98.3% in plate group; and the results were excellent in 26 cases, good in 11 cases, and poor in 1 case, with an excellent and good rate of 97.4% in minimally invasive group; showing no significant difference (χ2=0.10, P=0.75).ConclusionMinimally invasive fixation with titanium elastic nail has such advantages as small damage, quick recovery, no skin scarring, etc. As long as the correct indication is selected, minimally invasive titanium intramedullary nail internal fixation of Galeazzi fractures can also get good effectiveness.

    Objective To compare the effectiveness of locking plate and intramedullary nail in treatment of Neer two- and three-part fractures of the proximal humerus in the elderly. Methods A retrospective analysis was conducted on 86 elderly patients with Neer two- and three-part fractures of the proximal humerus met the selection criteria between January 2015 and December 2018. Forty-six patients were treated with locking plate fixation (locking plate group), and 40 patients with intramedullary nail fixation (intramedullary nail group). There was no significant difference in gender, age, cause of injury, fracture side and type, time from injury to operation, and comorbidities between the two groups (P>0.05). Visual analogue scale (VAS) score, American Shoulder and Elbow Surgery (ASES) score, Constant-Murley score, and shoulder range of motion (forward flexion, abduction, and external rotation) were compared between the two groups. X-ray films were taken to assess the fracture healing, and the neck-shaft angle was measured at 2 days after operation and at last follow-up, and the difference between the two time points was calculated. Results Patients in both groups were followed up 18-40 months, with an average of 30.4 months. There was no significant difference in follow-up time between the two groups (t=−0.986, P=0.327). X-ray films reexamination showed that the fractures of two groups healed, and the healing time was (11.3±2.1) weeks in locking plate group and (10.3±2.0) weeks in intramedullary nail group, which had significant difference between the two groups (t=2.250, P=0.027). The difference of neck-shaft angle was (7.63±7.01)° in locking plate group and (2.85±2.82)° in intramedullary nail group, which had significant difference between the two groups (t=4.032, P<0.001). There was no significant difference in Constant-Murley score, ASES score, VAS score, and shoulder range of motion between the two groups at last follow-up (P>0.05). Complications occurred in 13 cases (28.3%) of locking plate group and in 4 cases (10.0%) of intramedullary nail group, and the difference between the two groups was significant (χ2=4.498, P=0.034). Conclusion Both locking plates and intramedullary nails can be used for the treatment of Neer two- and three-part fractures of the proximal humerus in the elderly. The intramedullary nail fixation surgery is more minimally invasive, which has fewer postoperative complications and faster fracture healing.

  • Development and clinical application of a new type of intramedullary nail tail cap

    Objective To develop a new type of tail cap for closing the tail of the central hole of the interlocking intramedullary nail so as to reduce difficulty in implantation of the tail cap into intramedullary nail, and ensure the accuracy of implantation, as well as reduce unnecessary operation time. Methods In 2014, the new type of intramedullary nail tail cap (" new tail cap” for short) was successfully developed, and has been granted national utility model patent. A randomized controlled clinical trial was conducted in 34 patients with non pathological femoral shaft fractures treated between August 2014 and March 2016. The patients were randomly divided into groups A and B, 17 patients each group. There was no significant difference in gender, age, side, body mass index, cause of injury, injury to operation time, and fracture AO classification between groups (P>0.05), with comparability. All patients underwent fixation with interlocking intramedullary nail, and the new tail cap and original tail cap were used in groups A and B respectively. The blood loss and operation time during tail cap implantation, fracture healing time, and complications were recorded and compared between 2 groups; the limb function was evaluated by Klemm function evaluation standard. Results The blood loss and operation time during tail cap implantation of group A [(3.5±0.8) mL and (10.57±3.15) s] were significantly less than those of group B [(5.5±1.7) mL and (21.99±6.90) s] (t=–8.281,P=0.010;t=–10.743,P=0.009). All new tail caps were successfully implanted by one-time in group A, and the one-time success rate was 100%; the original tail cap exfoliation occurred in 3 cases of group B, and the one-time success rate was 82.4%. All the patients were followed up 6-16 months (mean, 9.7 months); there was no deep infection, loosening or breakage of internal fixation, and other serious complications. The time of fracture healing was (16.4±3.2) weeks in group A and (15.8±3.5) weeks in group B, showing no significant difference (t=0.514,P=0.611). At last follow-up, according to the Klemm function evaluation standard, the results were excellent in 14 cases and good in 3 cases in group A, and were excellent in 11 cases and good in 6 cases in group B, showing no significant difference between 2 groups (χ2=0.142,P=0.707). Conclusion The new type of femoral intramedullary nail tail cap can simplify operation, shorten operation time, and reduce blood loss, and it has satisfactory effectiveness.

    Objective To analyze and compare the effectiveness of the closed reduction with elastic intramedullary nail ing and open reduction with Kirschner wire fixations in the treatment of O’Brien type III radial neck fractures in children. Methods Between November 2007 and November 2010, 31 children with O’Brien type III radial neck fractures were treated by the closed reduction with elastic intramedullary nailing fixation (closed reduction group, n=18) and by the open reduction with Kirschner wire fixation (open reduction group, n=13). There was no significant difference in age, gender, disease duration, and fracture classification between 2 groups (P gt; 0.05). Results The incisions of 2 groups healed primarily. Allthe patients were followed up 1-2 years (mean, 1.5 years). Limitation of the elbow extension occurred in 2 cases of the closed reduction group, l imitations of the elbow extension, flexion, and forearm pronation in 6 cases of the open reduction group. There was no significant difference in elbow flexion, extension, pronation, and supination between affected side and normal side in the closed reduction group (P gt; 0.05). Except in supination (P gt; 0.05), there were significant differences in flexion, extension, and pronation between affected side and normal side in the open reduction group (P lt; 0.05). According to Metaizeau’s grading criterion, excellent results were achieved in 16 cases and good in 2 cases in the closed reduction group; excellent results were achieved in 4 cases, good in 4 cases, fair in 3 cases, and poor in 2 case in the open reduction group; and there was significant difference between 2 groups (Z=3.435, P=0.001). The X-ray films showed anatomical reduction in 2 groups before removal of internal fixation; redisplacement occurred in 4 cases after removal of internal fixation in the open reduction group, no redisplacement occurred in the closed reduction group. There was no avascular necrosis of radial head and epi physes during follow-up. Conclusion Comparison with the open reduction with Kirschner wire fixation, the closed reduction with elastic intramedullary nailing fixation is a rel iable and good treatment for O’Brien type III radial neck fractures in children, because it has the advantages of minimal invasion, easy operation, stable fixation, early mobilization, and less complication.

  • COMPARISON OF TWO DIFFERENT OPERATIONS ON COMMINUTED INTERCONDYLAR FRACTURE

    Objective To compare the effect of two different operations on treating severely comminuted intercondylar fracture. Methods From December 2001 to October 2003, 20 cases of severely comminuted intercondylar fracture were operated. Of the 20 cases, 7(group 1) were treated with closed reduction and retrograde intramedullary nailing through arthroscope, 13(group2) were treated with open reduction and retrograde intramedullary nailing without arthroscope. Follow-ups were conducted after operation. Results All cases of fracture were recovered. Swelling in group 1 was alleviated more obviously than that in group 2. In group 1, all knees could flex to 120° during 6th to 9th weeks after the operation. In group 2, only 4 could flex 110°.Conclusion Retrograde intramedullary nailing through arthroscope proves to be less invasive and more effective in treating heavily comminuted intercondylar fracture.
