Titanium elastic nails for pediatric femur fractures: lessons from the learning curve

Traditionally, the treatment of choice in managing pediatric femur fractures has been traction and casting. Newer methods have focused on earlier mobility and shorter hospitalization. Use of retrograde titanium elastic nails (TENs) can quicken stabilization while allowing enough motion at the fracture site to generate excellent callus. Since TENs were first introduced in North America, our Level 1 Pediatric Trauma Center has prospectively followed all of its TEN patients. In this article, we present lessons from the learning curve of our first 50 cases--focusing on complications and their prevention. In the course of obtaining predominately excellent results, we have learned several important principles regarding TEN preoperative planning, operative technique, and aftercare. The most common problem encountered has been irritation at the nail insertion site (18% of cases). Very proximal fractures may be more challenging; unstable fractures and fractures in larger, older children are best managed with a short period of adjunctive immobilization.     

Elastic nailing of tibia shaft fractures in young children up to 10 years of age

IntroductionAlthough tibia shaft fractures in children usually have satisfactory results after closed reduction and casting, there are several surgical indications, including associated fractures and soft tissue injuries such as open fractures. Titanium elastic nails (TENs) are often used for pediatric tibia fractures, and have the advantage of preserving the open physis. However, complications such as delayed union or nonunion are not uncommon in older children or open fractures. In the present study, we evaluated children up to 10 years of age with closed or open tibial shaft fractures treated with elastic nailing technique.MethodsA total of 16 tibia shaft fractures treated by elastic nailing from 2001 to 2013 were reviewed. The mean patient age at operation was 7 years (range: 5–10 years). Thirteen of 16 cases were open fractures (grade I: 4, grade II: 6, grade IIIA: 3 cases); the other cases had associated fractures that necessitated operative treatments. Closed, antegrade intramedullary nailing was used to insert two nails through the proximal tibial metaphysis. All patients were followed up for at least one year after the injury. Outcomes were evaluated using modified Flynn's criteria, including union, alignment, leg length discrepancies, and complications.ResultsAll fractures achieved union a mean of 16.1 weeks after surgery (range: 11–26 weeks). No patient reported knee pain or experienced any loss of knee or ankle motion. There was a case of superficial infection in a patient with grade III open fracture. Three patients reported soft tissue discomfort due to prominent TEN tips at the proximal insertion site, which required cutting the tip before union or removing the nail after union. At the last follow-up, there were no angular or rotational deformities over 10° in either the sagittal or coronal planes. With the exception of one case with an overgrowth of 15 mm, no patient showed shortening or overgrowth exceeding 10 mm. Among final outcomes, 15 were excellent and 1 was satisfactory.SummaryEven with open fractures or soft tissue injuries, elastic nailing can achieve satisfactory results in young children, with minimal complications of delayed bone healing, or infection.     

The definition and treatment of pediatric subtrochanteric femur fractures with titanium elastic nails

PURPOSE: Titanium elastic nailing (TEN) has become more common in the treatment of pediatric femur fractures in many European centers and in North America over the past several years. Prior studies have shown that the use of TEN for midshaft femur fractures results in excellent outcomes with an earlier return to activity, earlier mobilization, and a shortened hospital stay. However, subtrochanteric femur fractures continue to remain a difficult subset of fractures to care for, with loss of reduction and nonunion being significant complications. Studies have differed regarding the definition of pediatric subtrochanteric femur fractures. The purpose of this study is to establish a reproducible method of defining pediatric subtrochanteric fractures and then apply that definition in a retrospective review of 13 patients who sustained subtrochanteric femur fractures treated with TEN at North Carolina Baptist Hospital using a modified technique that allows for improved fracture stability. METHODS: Charts and radiographs were retrospectively reviewed for all pediatric patients sustaining subtrochanteric femur fractures treated with TEN from the period of 2000 to 2004 at Wake Forest University. The TEN outcome measures scale was applied to determine their results. RESULTS: TEN allowed rapid mobilization with excellent or satisfactory clinical and radiographic results in all patients. CONCLUSIONS: Results suggest that the use of TEN for subtrochanteric femur fractures is a safe and effective method of fixation that benefits patients through early mobilization, shorter hospital stays, and fewer complications. SIGNIFICANCE: By applying the definition of subtrochanteric femur fractures described by the authors, results of future studies can be objectively compared and classified. TEN is a safe and effective alternative for treating most pediatric subtrochanteric fractures by decreasing the morbidity that occurs with other treatment modalities.

Temporizing Management of Pediatric Femur Fractures Using J-splints

This article describes a novel splinting technique for the temporizing management of pediatric femur fractures. The J-splint is a reliable, simple, and rapidly applied splint that prevents many of the complications and pitfalls of other described temporizing measures, such as skeletal traction, skin traction, traction splinting, and posterior splinting. This technique of J-splinting femur fractures has low morbidity and provides many advantages in the temporizing management of pediatric femur fractures.     

Titanium elastic nails for pediatric tibial shaft fractures

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.

Use of a stockinette in closed reduction of distal extra-articular tibia fractures

Tibia fractures are common orthopaedic injuries. One of the most difficult tibia fractures that physicians encounter is the extra-articular distal third fracture. Operative fixation has certain risks depending on the procedure. Intramedullary nails fail to obtain adequate distal locking, and plate fixation increases the risk of soft tissue complications. Therefore, when indicated, closed reduction should be attempted. We have devised a method of applying in-line traction while performing closed reduction and casting with the use of a stockinette. This method avoids many of the problems encountered with other techniques such as calcaneal traction pins and hair splints. With the use of in-line traction through the stockinette, we are able to apply traction throughout casting without assistance, and the procedure is noninvasive.

Surgical treatment of traumatic pediatric humeral diaphyseal fractures with titanium elastic nails

Background  Nearly all pediatric humeral shaft fractures can be successfully treated with closed methods. Some patients, however, require internal fixation either because of an inability to maintain an adequate reduction, significant soft tissue injury, or concomitant fractures. Methods  This is a retrospective review of all traumatic humeral shaft fractures treated at our hospitals between 1999 and 2006. Thirteen pediatric patients ranging in age from 4.8 to 16.7 years (mean age 12.0 years) were treated surgically with titanium elastic nails (TENs). Relative surgical indications included open fractures, inability to maintain an acceptable reduction, the presence of ipsilateral forearm fractures (floating elbow), concomitant lower extremity fractures, and closed head injury. Two patients had associated radial nerve injury at presentation. Results  The patients were followed for a mean of 29 months. All fractures healed in good alignment. There were no intraoperative complications, including neurologic or vascular injury, and no patient developed an infection postoperatively. Two patients had nail migration, one of whom developed nail protrusion through the skin. One patient with preoperative radial nerve injury ultimately underwent tendon transfer to restore wrist extension. Of the 13 patients, 12 reported a full return to sports and other activities with no limitations or discomfort. Conclusions  When surgical stabilization of pediatric humeral shaft fractures is indicated, TEN fixation is effective and has a high rate of union and a low rate of complications. This technique is familiar to most orthopaedic surgeons treating pediatric fractures. Level of evidence  Level of evidence: IV (case series) This study was conducted at Washington University School of Medicine, St. Louis Shriners Hospital for Children, and St. Louis Children’s Hospital, St. Louis, Missouri, USA.     

Internal fixation versus traction and casting of adolescent femoral shaft fractures

We compared the results of traction plus subsequent casting with rigid internal fixation in a large series of adolescent femoral shaft fractures. Of 90 patients with 96 femoral shaft fractures, 49 (52 fractures) underwent rigid internal fixation, whereas 41 (44 fractures) underwent traction and subsequent casting until healing occurred. The traction and casting group had a mean hospital stay of 26 days. The operative group had a mean hospital stay of 9 days and had fewer complications than the nonoperative group. Adolescent femoral shaft fractures can be operatively treated with excellent results and a decreased complication rate. Operation results in shorter hospitalization, which has psychological, social, educational, and economic advantages over conservative treatment.     

Complications and conversions of pediatric videosurgery

Background: The aim of this study was to evaluate the incidence and management of complications of videosurgical procedures that occurred during a 4-year period in eight Italian pediatric surgery centers. Methods: Between 1996 and 1999, 2305 videosurgical procedures were performed in 11 centers of pediatric surgery. The data from 3 centers, for a total of 616 procedures, were largely incomplete and were thus excluded from the study. We analyzed the data from 8 centers only, for a total of 1689 laparoscopic or thoracoscopic operations on patients aged between 15 days and 16 years. The type of operations performed ranged from basic videosurgical interventions, such as varicocelectomy and cryptorchidism, to advanced laparoscopic procedures, such as splenectomy, total colectomy, and esophageal achalasia. Each patient's file was examined for any complications that may have occurred during the surgical procedure and for a record of how these were managed. Results: We recorded 79 complications (4.6%) in our series. In 57 cases (72.2%) the problem was solved by videosurgery. Twenty-two cases (27.8%) required conversion to open surgery. There was no mortality in our series. At a maximum follow-up of 4 years, all children were alive and had no problems related to the videosurgical complications. Conclusions: We believe that the routine use of open laparoscopy in pediatric patients is a key factor to avoiding complications related to the Veress needle and blind introduction of the first trocar. Moreover, the surgeon's laparoscopic experience, the correct indications for laparoscopic surgery, and the verification of the laparoscopic equipment before surgery are also important rules to follow to reduce the incidence of complications. In the beginning, it is preferable to have the assistance of an expert laparoscopic surgeon to decrease the complications related to the learning curve period.     

Stabilization of pediatric diaphyseal femur fractures with flexible intramedullary nails (a technique paper).

The indications for surgical stabilization of a pediatric diaphyseal femur fracture are expanding. Children with multiple system injuries, a head injury, and/or multiple fractures have fewer local and distant complications if the femur fracture is treated operatively. Other indications include a pathological fracture in osteoporotic bone, a fracture in a child with a preexisting condition that prevents the application of a spica cast, a child older than 10 years of age, or a child less than 10 years of age who cannot be kept adequately aligned using conventional (traction/casting) methods of fracture management. Here we describe a technique of stabilizing pediatric diaphyseal femur fractures using flexible intramedullary nails (Ender). This technique can be used in children of all ages and with all patterns of diaphyseal fractures.     

Complications of pediatric urological laparoscopy: mistakes and risks

PURPOSE: We evaluate the results and complications of laparoscopic urological procedures in children. MATERIALS AND METHODS: In a 3-year period 4,350 laparoscopic procedures were performed at 8 Italian centers of pediatric surgery. We analyzed only the data of urological procedures for a total of 701 laparoscopic operations on patients 1 month to 14 years old. The indications for surgery were cryptorchidism in 414 cases, varicoceles in 159, ambiguous genitalia in 37, total nephrectomy in 34, partial nephrectomy in 4, adrenalectomy in 3 and other diagnostic procedures in 50. We adopted a retroperitoneoscopic approach in 72 cases (10.3%) and a laparoscopic approach in 629 (89.7%). Patient records were analyzed to search for any complication that may have occurred during the laparoscopic procedure and assess how they were managed. RESULTS: We recorded 19 complications (2.7%) in our series, of which 6 required conversion to open surgery and 13 did not. There was no mortality. At a maximum followup of 4 years all children were alive and had no problems related to the laparoscopic complications. CONCLUSIONS: Our study shows that pediatric laparoscopic urological surgery has an acceptable rate of complications with no mortality. We believe that routine use of open laparoscopy in pediatric patients is a key factor to help avoid complications. Most complications can be avoided with surgeon and team experience, together with proper compliance with the indications for surgery.     

Elastic stable intramedullary nailing of tibial shaft fractures in children

Most pediatric tibia shaft fractures are amenable to nonoperative treatment with satisfying results, yet surgical stabilization is necessary in certain cases. The purpose of our study was to determine the effectiveness and the complications associated with elastic stable intramedullary nailing in severe pediatric tibial fractures. We retrospectively reviewed 24 tibia shaft fractures in 24 patients that were treated operatively by elastic stable intramedullary nailing between 1997 and 2005 at our institution. Extensive review of all charts and radiographic data was completed at Cincinnati Children's Hospital Medical Center. There were 8 closed and 16 open fractures. The average union time for all tibia fractures was 20.4 weeks. The average union time for closed and open fractures was 21.5 and 20.2 weeks, respectively. Complications include 2 (8%) neurovascular, 2 (8%) infections, 2 (8%) malunions, and 1 (4%) leg-length discrepancy. Although complications do exist, elastic stable intramedullary nailing of pediatric tibia shaft fractures using Nancy nails is an effective treatment option.     

Advantages of submuscular bridge plating for complex pediatric femur fractures

Conventional treatments of pediatric femoral shaft fractures may result in an unacceptable rate of complications, especially in complex fractures. These fractures include high-energy injuries resulting in unstable fracture patterns, fractures in the proximal or distal third, and fractures occurring in large or multiply injured children. Our goal was to evaluate whether a minimally invasive submuscular bridge plating technique provides stability for early functional treatment (without protective casting or bracing) and predictable healing. Fifty-one patients with an average age of 10 years were studied. Sixty-seven percent had high-energy injuries and 55% had unstable fracture patterns. With an average followup of 14.2 months, all fractures united with excellent clinical results. Two (4%) significant complications occurred: fracture of one 3.5-mm LC-DCP Ti plate, and refracture of a pathologic fracture after early plate removal. Four patients (8%) had a leg-length discrepancy ranging from 23-mm short to 10-mm long. The average operative time was 106 minutes, with average fluoroscopy time of 84 seconds. Procedures were done by 15 surgeons in five university medical centers. This technique offers the advantage of adequate stability for early functional treatment and predictable healing with maintenance of length and alignment for all pediatric femoral shaft fractures.     

Diaphyseal femoral fractures below the age of six years: Results of plaster application and long term followup

Background:

In children less than 6 years, the treatment of femoral shaft fracture is often non surgical, using closed reduction and casting. The literature reports many experience about this type of trauma but none of these has a long term followup. We present a retrospective study on a group of femoral diaphyseal fractures treated nonsurgically in children up to 6 years of age, with a minimum of 10 year followup.

Materials and Methods:

48 cases (36 males/12 females) with femoral diaphyseal fractures treated between January 1988 and December 1998 were reviewed. Patients with fractures due to obstetrical trauma and pathologic fractures were excluded. The mean age of the patients was 3.3 ± 1.1 years (range 5 months-6 years). Right side was involved in 21 cases (44%), and left side in 27 cases (56%). In 34 cases (71%), closed reduction was performed and hip spica was applied with the hip and knee flexed to 45°. In 8 cases (17%), skeletal traction was applied to perform fracture reduction and the traction pin was embedded in plaster while in the remaining 6 cases (12%), the Delitala pressure apparatus was applied after casting.

Results:

All fractures healed in our study. There were no complications (infection or vascular nervous issues, axial deviations, consolidation delays, or pseudoarthrosis). In 13 cases (27%), followup examinations showed mean lengthening of 1.3 ± 0.75 (range 0.5-2.5 cm) of the fractured lower limb. All these patients were treated with skin traction before treatment and presented with 2.08 ± 0.28 cm mean initial femoral shortening. In 1 case (2%) with 2.5 cm lengthening, epiphysiodesis of the ipsilateral knee was performed. No patients showed prolonged difficulty with gait disorders.

Conclusion:

On the basis of our results conservative treatment of femoral shaft fractures in children can be considered less invasive and safe procedure.     

Outcomes of orthotopic liver transplantation in Chile

Our liver transplant program was started in 1993 in a private clinic and a public hospital. Thereafter, a rapid increase in adults and pediatric candidates for this therapeutic option lead to this analysis of results in 165 orthotopic liver transplants (OLT) in 143 patients between November 1993 and December 2002. Seventy-four OLT were performed in 66 adult patients and 91 in the pediatric group. Liver grafts came from cadaveric donors in 145 cases (74 adults and 71 children). The technique of living-related donor was utilized in 20 pediatric cases. Main indications for OLT in the adult group were HCV cirrhosis, primary biliary cirrhosis; biliary atresia and acute liver failure were the indications in pediatric patients. Retransplantation was needed for 23 patients, including 9 adults and 14 children. The most frequent causes of death were sepsis, graft primary nonfunction, and vascular complications. Actuarial survivals at 1 and 5 years were 80.7% and 72.6% for the adult group and 82% and 74.8% for the pediatric group, respectively. Our results are comparable to those published by large, experienced, international centers, with much better financial support.
