ObjectiveTo evaluate the effectiveness of titanium elastic nails for severe displaced proximal humeral fractures in older children. MethodsBetween April 2009 and July 2012, 31 cases of severe displaced proximal humeral fractures were treated with closed or open reduction and fixation with 2 titanium elastic nails, and the clinical data were retrospectively analyzed. There were 23 boys and 8 girls, aged from 10 to 15 years (mean, 12.8 years). The causes of injury were sports injury (16 cases), traffic accident (11 cases), and falling from height (4 cases). The interval from injury to operation was 6 hours to 7 days (mean, 72 hours). According to Neer-Horwitz classification, 17 cases were rated as type III fracture and 14 cases as type IV fracture. There were 21 cases of metaphyseal fractures and 10 cases of epiphyseal fractures. ResultsSatisfactory reduction of fracture and stable fixation were obtained in all patients (closed reduction in 23 cases and open reduction in 8 cases). Primary healing was achieved in all incisions; no infection and neurovascular injury occurred. All patients were followed up 12-36 months with an average of 20 months. X-ray films showed that all fractures healed at 7-10 weeks (mean, 8 weeks). During follow-up, no disturbance of development or angulation deformity caused by premature physeal closure or bone bridge formation was observed. At last follow-up, the average Neer score of the shoulder was 95.7 (range, 83-100). The appearance and motion of the shoulder were normal. There was no significant difference in the upper extremity length between affected side and contralateral side[(67.68±2.56) cm vs. (67.61±2.54) cm; t=-1.867,P=0.072]. ConclusionTitanium elastic nails for severe displaced humeral fractures in older children is a safe and effective method with a low complication incidence.
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 investigate the effectiveness of closed reduction and internal fixation with elastic nails in treatment of Mason type Ⅱ radial head fracture in adults.MethodsA clinical data of 28 patients with Mason type Ⅱ radial head fractures between May 2013 and March 2017 was retrospectively analyzed. Thirteen patients were treated with closed reduction and internal fixation with elastic nails (trial group); 15 patients were treated with open reduction and internal fixation with Herbert screws (control group). There was no significant difference in gender, age, cause of injury, side of fracture, and the time from injury to operation between the two groups (P>0.05). The operation time, blood loss, and fluoroscopy times in the two groups were recorded and compared. Postoperative X-ray films were used to evaluate the bone healing, heterotopic ossification, and necrosis of radial head. The effectiveness was evaluated according to Mayo score criteria of the elbow at last follow-up. ResultsAll patients were followed up 12-30 months (mean, 21.9 months). The operation time and blood loss were significantly less in the trial group than in the control group (P<0.05), while the fluoroscopy times significantly increased in the trial group than in the control group (P<0.05). X-ray films showed that all fractures healed with the bone healing time of (2.85±0.69) months in the trial group and (3.35±0.88) months in the control group. There was no significant difference in bone healing time between the two groups (t=1.654, P=0.110). Heterotopic ossification occurred in 2 cases in the control group. At last follow-up, there was no significant difference in the Mayo scores between the trial group (90.6±5.3) and the control group (86.4±7.1) (t=1.750, P=0.092).ConclusionClosed reduction and internal fixation with elastic nails, as a minimally invasive technique, has advantages of short operation time and less bleeding in the treatment of Mason type Ⅱ radial head fracture.
Objective To investigate the surgical technique and effectiveness of titanium elastic nail (TEN) assisted retrograde channel screw implantation of superior pubic branch. Methods The clinical data of 31 patients with pelvic or acetabular fractures treated with retrograde channel screw implantation in superior pubic branch between January 2021 and April 2022 were retrospectively analyzed. Among them, 16 cases were implanted with assistance of TEN (study group) and 15 cases were implanted under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification of pelvic fracture, Judet-Letournal classification of acetabular fracture, and time from injury to operation between the two groups (P>0.05). The operation time, fluoroscopy times, and intraoperative blood loss of each superior pubic branch retrograde channel screw were recorded during operation. X-ray films and three-dimensional CT were reexamined after operation, the quality of fracture reduction was evaluated by Matta score standard, and the position of channel screw was evaluated by screw position classification standard. The fracture healing time was recorded during the follow-up, and the postoperative functional recovery was evaluated by Merle D’Aubigne Postel score system at last follow-up. Results Nineteen and 20 retrograde channel screws of superior pubic branch were implanted in the study group and the control group, respectively. The operation time, fluoroscopy times, and intraoperative blood loss of each screw in the study group were significantly less than those in the control group (P<0.05). According to the postoperative X-ray films and three-dimensional CT, none of the 19 screws in the study group penetrated out of the cortical bone or into the joint, and the excellent and good rate was 100% (19/19); in the control group, there were 4 screws of cortical bone penetration, and the excellent and good rate was 80% (16/20); the difference between the two groups was significant (P<0.05). Matta score standard was used to evaluate the quality of fracture reduction, there was no patient in the two groups with poor reduction results, and the difference was not significant between the two groups (P>0.05). The incisions of the two groups healed by first intention, and there was no complication such as incision infection, skin margin necrosis, and deep infection. All patients were followed up 8-22 months, with an average of 14.7 months. There was no significant difference in healing time between the two groups (P>0.05). At last follow-up, the difference in functional recovery evaluated by the Merle D’Aubigne Postel scoring system between the two groups was not significant (P>0.05). Conclusion TEN assisted implantation technique can significantly shorten the operation time of retrograde channel screw implantation of superior pubic branch, reduce the times of fluoroscopy, and have less intraoperative blood loss and accurate screw implantation, which provides a new safe and reliable method for minimally invasive treatment of pelvic and acetabular fractures.
