Defining length stability in paediatric femoral shaft fractures treated with titanium elastic nails

IntroductionOptimal paediatric femoral shaft fracture patterns or lengths amenable to titanium elastic nail stabilization have not been well defined. The purpose of this study is to identify radiographic parameters predictive of treatment failure with flexible intramedullary nails based upon fracture morphology.MethodsA retrospective review was performed of all femoral shaft fractures treated with flexible intramedullary nails over a five-year period. All patients with at least six weeks of postoperative radiographic imaging were included. Fracture characteristics included location, pattern, length, obliquity, angulation, translation and shortening. Postoperative radiographs were reviewed to determine shortening and angulation.ResultsThere were 58 patients with 60 femoral shaft fractures stabilized with titanium nails, with 46 healing within acceptable parameters and 14 considered malunions. Six of the 14 malunions developed complications requiring early unplanned intervention. No patients in the treatment success group had a complication. Between the treatment success and failure groups, fracture pattern, location, length, obliquity, angulation, translation or shortening were not statistically different. Mean nail canal fill was significantly lower in the failure group (0.72 versus 0.81; p = 0.0146), with a receiver operating characteristic curve identifying canal fill 76% as the optimal threshold.ConclusionThis is the first study to measure the length and obliquity of paediatric femoral shaft fractures and to determine their relationship to radiographic alignment after healing. None of the preoperative fracture characteristics were predictive of malalignment or shortening. We recommend the use of larger nail sizes in the treatment of paediatric femoral shaft fractures, especially if there is concern for residual instability.Level of evidenceIV     

Clinical outcomes of midclavicular fractures treated with titanium elastic nails

Background

Midclavicular fractures are common clinically, accounting for about 76% of all clavicular fractures. Recent studies have revealed a previously unrecognized incidence of nonunion and malunion after conservative treatment of more severe midclavicular fractures. Our aim was to evaluate the clinical outcomes of midclavicular fractures treated with titanium elastic nails.

Methods

From February 2005 to February 2007, 41 patients with displaced midclavicular fractures received open reduction and internal fixation with a titanium elastic nail inserted through the sternal end of the clavicle. We evaluated the visual analogue scale (VAS), the Constant score and the Disabilities of the Arm, Shoulder and Hand (DASH) scale to determine outcomes.

Results

A mean follow-up of 14.5 months (range 7–24 mo) revealed radiographic fracture union in all patients with an average clinical healing time of 2.2 months. Mean subjective pain 3 days after surgery was significantly lower than the day before surgery (p < 0.001). The mean range of motion 3 days after surgery was significantly improved compared with the day before surgery (p < 0.001). The nails were removed in all patients a mean of 7.2 months (range 5.4–9.5 mo) after surgery, and no fractures recurred. The mean postoperative DASH score was 2.5 (range 0.5–8.0) and the mean postoperative Constant score was 95.2 (range 86.5–97.0).

Conclusion

Limited open reduction and internal fixation with titanium elastic nails is a safe and minimally invasive surgical procedure for the treatment of displaced midclavicular fractures in adults and achieves good functional results and high patient satisfaction.

Closed/open reduction and titanium elastic nails for severely displaced proximal humeral fractures in children

Purpose

The aim of the study was to evaluate the clinical outcome of closed/open reduction and titanium elastic nails (TENs) in children with severely displaced proximal humeral fractures.

Methods

A retrospective study was performed on 37 children suffering from proximal humeral fracture between April 2009 and July 2012. All these patients were treated by closed or open reduction with TEN fixation. The healing process was assessed by radiographic and clinical follow-up for up to 36 months. Radiographic assessment was performed on the scheduled follow-ups to examine fracture healing, remodelling, bone growth and residual deformity. The clinical outcomes were evaluated using the Neer shoulder score and patients’ satisfaction report at the final follow-up. Complications related to the treatment were also recorded.

Results

All patients had a mean follow-up period of 24 months (12–36) after surgery. All fractures were healed, radiologically, at a median time of eight weeks (seven to ten weeks). There were no major complications related to the treatment. Two patients complained about skin irritation around the sides of the prominent distal ends of the nails. Implant removal took place at an average of 5.8 months post-operatively as an outpatient procedure. There were no observed complications in association with the removal of the hardware. At the final follow-up, the mean Neer shoulder score was 96.65 (range 83–100). Thirty patients were very satisfied with their surgical outcomes and the remaining seven were satisfied. Function of the affected arm returned to normal at the end of the follow-up period in all cases.

Conclusions

Combining closed or open reduction with TEN fixation is recommended for treating severely displaced proximal humeral fractures in children. Our data showed evidence of satisfactory outcomes with a low complication rate and a fast return to normal mobility of the affected arms.     

Computational comparison of tibial diaphyseal fractures fixed with various degrees of prebending of titanium elastic nails and with and without end caps

IntroductionElastic stable intramedullary nailing (ESIN) is a treatment strategy for the management of diaphyseal long-bone fractures in adolescents and children, but few studies have investigated the mechanical stability of tibial diaphyseal fractures treated with various degrees of prebending of the elastic nails. Therefore, the aim of this study was to compare the mechanical stability, including the gap deformation and nail dropping, of a tibia fracture with various fracture sites and fixed with various degrees of prebending of the elastic nails by the finite element method. Furthermore, the contribution of end caps to stability was taken into consideration in the simulation.MethodsA tibia model was developed with a transverse fracture at the proximal, middle and distal parts of the diaphysis, and fixed with three degrees of prebending of elastic nails, including those equal to, two times and three times the diameter of the intramedullary canal. The outer diameter of the nail used in the computation was 3.5 mm, and the fractured tibia was fixed with two elastic double C-type nails. Furthermore, the proximal end of each nail was set to free or being tied to the surrounding bone by a constraint equation to simulate with or without using end caps.ResultsThe results indicated that using end caps can prevent the fracture gap from collapsing by stopping the ends of the nails from dropping back in all prebending conditions and fracture patterns, and increasing the prebending of the nails to a degree three times the diameter of the canal reduced the gap shortening and the dropping distance of the nail end in those without using end caps under axial compression and bending. Insufficient prebending of the nails and not using end caps caused the gap to collapse and the nail to drop back at the entry point under loading.ConclusionsUsing end caps or increasing the prebending of the nails to three times the diameter of the canal is suggested to stop the nail from dropping back and thus produce a more stable structure, with less gap deformation, in the management of a simulated tibial diapyhseal fracture by using titanium elastic nails with a double C-shape.
