Purpose The purpose of our study was to investigate the safety and efficacy of elastic stable intramedullary nailing for unstable
pediatric tibial shaft fractures using titanium elastic nails (TENs). To our knowledge, this is the largest series reported
in the literature of this specific fixation technique.
Methods We reviewed all children with tibial shaft fractures treated operatively at our tertiary care children's hospital to find
those patients who underwent fixation with TENs. Between 1998 and 2005, we identified 19 consecutive patients who satisfied
inclusion criteria. The average age of the patients in our series was 12.2 years (range 7.2–16 years), and mean follow-up
was 15.7 months (range 6–28 months). Patient charts and radiographs were retrospectively reviewed to gather the clinical data.
Outcomes were classified as excellent, satisfactory, or poor according to the Flynn classification for flexible nail fixation.
Results All patients achieved complete healing at a mean of 11.0 weeks (range 6–18 weeks). At final follow-up, mean angulation was
2° (range 0°–6°) in the sagittal plane and 3° in the coronal plane (range 0°–9°). Five patients (26%) complained of irritation
at the nail entry site; there were no leg length discrepancies or physeal arrests as a result of treatment. Two patients required
remanipulation after the index procedure to maintain adequate alignment. According to the Flynn classification, we had 12
excellent, six satisfactory, and one poor result.
Conclusion Although the indications for operative fixation of pediatric tibial shaft fractures are rare, occasionally surgical treatment
is warranted. Based on our results, elastic stable intramedullary nailing with titanium elastic nails is an effective surgical
technique which allows rapid healing of tibial shaft fractures with an acceptable rate of complications.

Introduction
This retrospective study was designed to define the technical details for the treatment for distal tibial fractures with intramedullary nails and blocking screws, and to assess the effectiveness of the method based on our clinical practice.Materials and methods
Twenty-one patients in whom adequate reduction could not be achieved with distal tibial intramedullary nailing, blocking screws were inserted under fluoroscopy. Blocking screws were inserted from the medial side in eighteen patients, in the medial and anterior side in one patient, and in the posterior side in two patients. Patients were followed up clinically and radiologically. Fracture alignment and union were monitored by X-ray, and complications were noted.Results
Neutral alignment with union in both coronal and sagittal plane was achieved in all patients. None of the patients experienced infection. The only complication of the blocking screws was fissure in one patient in the location of the screw during surgery. In another patient, nonunion was developed with 8° flexion angle. Union was achieved in this patient at 9?months with auto grafting.Conclusion
Blocking screws helped to achieve better reduction and alignment with intramedullary nailing of distal tibial fractures by decreasing the effective diameter of the medullary canal. The use of blocking screws enabled to use the intramedullary nailing as an alternative while treating distal tibial fractures. 相似文献3.

Introduction
A tibial nail with fixed-angle locking screws intends to combine the advantages of angular stability and intramedullary stabilization in extraarticular proximal tibial fractures. The goal of this study is to analyze if the angle stable tibial nail (ASN) is biomechanically more stable than an established conventional standard nail (CN). 相似文献4.

Fractures of the femoral shaft are generally considered to affect young patients, but we have reviewed 24 cases in patients over 60 years who have been treated by locked nailing, usually by closed methods. Most were women with low-velocity injuries, but despite this, 14 fractures were significantly comminuted. The complication rate was 54% with a peri-operative mortality of 17%. Most complications were the general ones of operating on elderly patients. Specific complications included: fractures below an abnormal hip, proximal fracture related to the nail and poor purchase in the distal femur. In all survivors, the femoral shaft fractures united satisfactorily, and the fixation allowed early mobilisation. The locking nail appears to be an effective method of managing femoral shaft fractures in the elderly patient. 相似文献

Unreamed nailing with solid tibial nails is an accepted method of treatment for open tibial shaft fractures up to grade III and of closed tibial fractures with severe soft tissue damage. However, fatigue failure of the distal locking bolts is a frequent complication. We report a mechanical study investigating the fatigue limit of six different types of locking bolts used in solid tibila nails (Biorigid Tibial nail/aap, UTN/ace, STN/Howmedica, TLN/Howmedica, delta R & T Tibial nail/Smith & Nephew, AO/ASIF UTN/Synthes). Our results prove a direct correlation between the bolt's diameter and mechanical properties. Further more we found that bolts with a continuing thread were weaker than bolts of the same diameter with only a short thread and an increased diameter at the nail's aperture. Our results suggest that mobilization with half of the average body weight (350N) allows osseous consolidation without fatique failure of any of the tested locking bolts. Some of the tested locking bolts may even withstand full wieght-bearing in a physiological walking cycle, but will not withstand the stress of a running cycle. 相似文献

Intramedullary locking nails have proved to be of considerable advantage when treating complex, comminuted or segmental femoral shaft fractures. We have reviewed 117 patients with 120 femoral shaft fractures treated with the Strasbourg device. These included 20 compound fractures, 13 pathological fractures and two non-unions. Rehabilitation and union rates have been very satisfactory and there have been no serious infections in the series. Comminution of the proximal femur has occurred in six patients and there have been three femoral neck fractures, but all of these have healed without further complications. 相似文献

Background
Intramedullary fixation is the treatment of choice for diaphyseal fractures of the femur and tibia. Locking the implant can sometimes be cumbersome and time consuming. In our institution, fractures with axial and rotational stability are treated with intramedullary nailing without interlocking.Methods
All consecutive patients presented in the University Medical Center Utrecht from October 2003 to August 2009 with acute traumatic diaphyseal fractures of the tibia or femur that were considered axial and rotational stable were included. They underwent internal fixation using intramedullary nails without interlocking. Patient records were evaluated for duration of surgery, perioperative complications, consolidation time and re-operations.Results
Twenty-nine long bone fractures were treated in 27 patients: 20 men and 7 women, with an average age of 28.9 years (range 15.6–54.4). There were 12 femoral fractures and 17 tibial fractures. Sixteen fractures were closed and 13 were open (10 Gustilo 1, 3 Gustilo 2). The mean operating time was 43 min (range 18–68 min) for tibial fractures and 55 min (range 47–150 min) for femoral fractures. Postoperative complications occurred in six patients. Two patients (three fractures) were lost to follow-up. Healing occurred in 25 of the 26 remaining fractures (96 %) without additional interventions. One tibia was secondarily converted to a standard locked nail because of axial and rotational instability. All patients returned to their pre-injury level of activity.Conclusion
The use of intramedullary nailing without interlocking is associated with minimal complications in selected fractures. The advantages include a short operating time and the simplicity of its application. 相似文献12.

Authors analyzed consecutive series of 56 tibial shaft fractures (43 men and 13 women) treated by intramedullary locking nails in years 1993-2004. Age of patients ranged from 17 to 83 years (mean 38 years). The final result was analyzed in 51 patients (91%). The bone union was observed in 50 patients. Fractures united within 6 months in 45 patients (88%), between 8 and 15 months in 5 patients. Operative treatment of non-union was necessary in one patient. The fractures united in anatomical axis in 45 cases, small (less than 10 degrees) valgus deviation was noticed in four patients, whereas five patients with fractures localized in distal part of the tibia had 11-30 degrees valgus deviation. The limb length inequality more than 1 cm was noticed in one case. There was neither infection nor compartment syndrome. One patient died because of fatal pulmonary embolism. 相似文献

The use of Ender nails in fractures of the tibial shaft 总被引:1,自引:0,他引:1
L Mayer T Werbie J P Schwab R P Johnson 《The Journal of bone and joint surgery. American volume》1985,67(3):446-455
Between November 1979 and January 1983, we treated fifty-one severe fractures of the tibial shaft with multiple intramedullary Ender nails. Thirty-six fractures were treated within two weeks after injury. Forty-one fractures united in less than four months and eight, in four to eight months. Only two were not united after eight months. An anatomical reduction was maintained in all but three of the fractures, in which the tibia shortened. Two tibiae united with an angulation of 7 degrees and one with 6 degrees, as measured in two planes. There were two infections, both after an open fracture. It has been our experience that Ender nails provide excellent rotational stability, allow early full weight-bearing, and markedly decrease the duration of need for immobilization. Ender nailing was of value both for the acute management of complicated high-energy fractures of the tibial shaft with extensive soft-tissue damage and as a salvage procedure to maintain reduction of a fracture when other techniques had failed. 相似文献

OBJECTIVES: To describe the technique and results of using blocking screws and intramedullary nails to treat patients with fractures of the proximal third of the tibial shaft. DESIGN: Prospective. SETTING: Level I trauma centers. PATIENTS: Twelve consecutive patients treated with intramedullary nailing and blocking screws for fractures of the proximal third of the tibial shaft. INTERVENTION: Patients were treated with intramedullary nails and blocking screws. MAIN OUTCOME MEASURE: The alignment of fractures was determined using standard anteroposterior and lateral radiographs after surgery and at each follow-up examination. One patient was lost to follow-up. All other patients were followed at regular intervals until union or establishment of a nonunion. Changes in alignment and complications were noted. RESULTS: Postoperatively, all patients had less than 5 degrees of angular deformity in the planes in which blocking screws were used to control alignment. One patient had postoperative malalignment (6 degrees of valgus), but a lateral blocking screw to control valgus deformity was not used in this patient. One patient was lost to follow-up. Eleven patients were followed up to union (n = 10) or establishment of a nonunion (n = 1). Ten of eleven patients maintained their postoperative fracture alignment at their last follow-up examination (average follow-up of thirty-three weeks). One patient progressed from 6 degrees of valgus immediately after surgery to 10 degrees of valgus at union. This patient did not have a blocking screw to control valgus angulation. CONCLUSIONS: Blocking screws are effective to help obtain and maintain alignment of fractures of the proximal third of the tibial shaft treated with intramedullary nails. 相似文献

In a series of 104 femoral and 50 tibioendomedullary nailings using Grosse-Kempf (G-F) locking nails, 24% of femoral fractures and 12% of tibial fractures were comminuted; 48% of the patients had multiple injuries. The nail was locked at proximal and distal levels in 54% of the cases for the femur. Dynamization of the nail was carried out at an average of 12 weeks. Nonweight-bearing was imposed for both series from three weeks to three months. Bone healing was achieved before six months in 100% of tibial fractures. Following Thoressen criteria, the results of femoral cases were all excellent and good; the percentage reached 96% for tibial cases. The G-F nail is suitable for high-energy, comminuted fractures. 相似文献

Intramedullary nailing of metaphyseal fractures may be associated with deformity as a result of instability after fixation. Our aim was to evaluate the clinical use of Poller screws (blocking screws) as a supplement to stability after fixation with statically locked intramedullary nails of small diameter. We studied, prospectively, 21 tibial fractures, 10 in the proximal third and 11 in the distal third in 20 patients after the insertion of Poller screws over a mean period of 18.5 months (12 to 29). All fractures had united. Healing was evident radiologically at a mean of 5.4+/-2.1 months (3 to 12) with a mean varus-valgus alignment of -1.0 degree (-5 to 3) and mean antecurvatum-recurvatum alignment of 1.6 degrees (-6 to 11). The mean loss of reduction between placement of the initial Poller screw and follow-up was 0.5 degrees in the frontal plane and 0.4 degrees in the sagittal plane. There were no complications related to the Poller screw. The clinical outcome, according to the Karstr?m-Olerud score, was not influenced by previous or concomitant injuries in 18 patients and was judged as excellent in three (17%), good in seven (39%), satisfactory in six (33%), fair in one (6%), and poor in one (6%). 相似文献

IntroductionThe purpose of this study was to determine the radiographic parameters associated with symptomatic locking screw removal after intramedullary tibial nail insertion. Our hypothesis was that locking screws located closer to joints and those extending longer than the width of the bone result in more symptomatic implant removal.MethodsWe conducted a retrospective cohort study at our Level I trauma center. Seventy-five patients underwent surgical removal of symptomatic locking screws from 2007 to 2014 and were compared with a control group of 122 patients from the same time period who did not undergo symptomatic locking screw removal. Our main outcome measures were radiographic and demographic factors associated with implant removal.ResultsMultivariable regression indicated that a proximal locking screw that started anterolateral and was directed posteromedial was the strongest radiographic predictor of symptomatic removal (odds ratio [OR], 2.83; p = 0.03). An Injury Severity Score <11 (OR, 3.10; p < 0.001) and a body mass index <25 kg/m2 (OR, 2.15; p = 0.02) were also associated with locking screw removal. The final prediction model discriminated patients requiring symptomatic locking screw removal with moderate accuracy (area under the receiver operating characteristic curve = 0.73).ConclusionsThe strongest radiographic predictor for symptomatic locking screw removal after tibial nail insertion was the direction of the most proximal locking screw. In contrast to previous research on retrograde femoral nails, tibial locking screws that were closer to the joints were not associated with an increased likelihood of symptomatic screw removal. Clinicians can use these data to help counsel patients regarding the likelihood of symptomatic screws and perhaps to help guide screw placement in cases with multiple options. 相似文献

Distal third tibial fractures are prone to non-union following tibial nail insertion. The purpose of this study was to assess the union of distal third tibial fractures in patients who have undergone intra-medullary (IM) tibial nailing with one versus two distal locking screws. Sixty-five patients who had intramedullary tibial nail fixation were retrospectively analysed. Our results showed that 80% of non-unions in distal third fractures had only one distal locking screw compared to 20% who had two distal locking screws. This is statistically significant (p<0.01). We therefore conclude that two distal locking screws are essential for distal third fractures. 相似文献
