RESUMO
OBJECTIVE: Reimbursement for surgical procedures is determined by a computation of the relative value unit (RVU) associated with CPT codes. It is based on the amount of work required to provide a service, resources available, and level of expertise involved. Given the evolution of changes in the limb lengthening field, we wanted to evaluate whether the RVU values were comparable across different orthopaedic subspecialties. Consequently, this study compares the work relative value unit (wRVU) totals of 3 common pediatric orthopaedic surgeries-arthroscopic ACL reconstruction, spinal fusion for adolescent idiopathic scoliosis, and antegrade femoral intramedullary limb lengthening. METHODS: This was an IRB-approved, multicenter, retrospective chart review. Charts of subjects who had ACL reconstructions, including meniscal repairs; spinal fusion surgeries for adolescent idiopathic scoliosis (7 to 12 levels), including Ponte osteotomies, and femoral antegrade internal limb lengthening procedures, each completed by fellowship-trained orthopaedic surgeons were reviewed. Comparisons were carried out between several parameters, including mean duration per procedure, number of CPT codes billed per procedure, number of postoperative visits in the 90-day global period, and the wRVU for each procedure. RESULTS: Fifty charts (25 per center) per procedure were reviewed. The wRVU per hour was lowest in the antegrade femur lengthening group ( P < 0.0001). The number of postoperative visits in the 90-day global postsurgery period was significantly higher in the antegrade femur lengthening group ( P < 0.0001). Intramedullary limb lengthening also had the least number of CPT codes billed. CONCLUSIONS: RVUs per time are statistically lowest in the limb lengthening group and highest in the scoliosis group. The limb lengthening patient also requires significantly more visits and time in the postoperative period compared with the other groups. These extra visits during the global period do not add any RVU value to the lengthening surgeon and occupy clinic spots that could be filled with new patients. Based on these data, a review of the RVU values assigned to the limb lengthening codes may be necessary. LEVEL OF EVIDENCE: Level III-retrospective comparison study.

Aim: The aim of the study is to demonstrate the safety and efficacy of the use of magnetically controlled intramedullary nails in patient with programmable implantable devices. Background: Magnetically driven intramedullary limb lengthening devices have revolutionised the field of limb reconstruction. Because the system is powered by strong magnets, there are warnings to avoid the use of the device in patients with implanted programmable devices, such as cardiac pacemakers. Materials and methods: Four patients with three different types of programmable implanted devices presented to two centres for limb lengthening and limb reconstruction. Each patient had a limb length discrepancy and desired correction using an intramedullary lengthening device. After thorough counselling about the potential risks and benefits of the procedure as well as discussions with each patient's medical team, the decision to proceed with surgery was made. Results: All four patients underwent osteoplasty with insertion of a magnetically driven intramedullary lengthening nail. Goal length was achieved with successful consolidation and subsequent nail removal in all patients. There were no malfunctions of the implantable devices during the distraction phase in any of the patients. Conclusion: With proper precautions, intramedullary lengthening can be performed safely and successfully using a magnetically driven nail in patients with previously implanted programmable devices. Clinical significance: This initial experience suggests use of magnetically controlled intramedullary nails in patient with programmable implantable devices can be undertaken safely within constraints of precautions.

RESUMO
UPDATE: This article was updated on December 20, 2023, because of previous errors, which were discovered after the preliminary version of the article was posted online. Figure 4 has been replaced with a figure that presents different p values. Also, on page 1943, the text that had read: "Quantitative microCT confirmed that the total volume of the regenerate in the RD group was much smaller compared with the SF (p = 0.06) and DF (p = 0.007) groups, although it was significantly smaller only compared with the DF group (Fig. 4-A). The total volume of the intact bone (contralateral tibia) was significantly smaller in the RD group compared with the other groups, but the RD group had values closest to those for the intact tibia. Similarly, the RD group had less bone volume compared with the SF and DF groups, and this value was significantly different from the DF group (p = 0.034; Fig. 4-B). Of the 3 groups, the RD group had vBMD that was the closest to that of intact bone. It also had significantly higher vBMD compared with the SF and DF groups (p < 0.0001 for both; Fig. 4-C).The results of torsional testing (Fig. 4-D) confirmed that the regenerate bone formed under conditions of RD was significantly stronger than that formed under SF or DF (p < 0.001 versus SF group, and p = 0.0493 versus DF group)."now reads: "Quantitative microCT confirmed that the total volume of the regenerate in the RD group was significantly smaller compared with the SF and DF groups (p < 0.01 for both groups; Fig. 4-A).

The concept of reverse dynamization involves modifying the mechanical environment surrounding a fracture to influence the healing response. Initially, less rigid stabilization is performed to allow micromotion, encouraging cartilaginous callus formation. This is followed by a conversion to more rigid fixation to prevent the disruption of neovascularization, thereby accelerating bone healing and remodeling. The effect of reverse dynamization in distraction osteogenesis has not been studied, to our knowledge. The aim of this study was to determine whether reverse dynamization can accelerate the formation and maturation of regenerate bone in a goat distraction osteogenesis model. Midshaft tibial osteotomies were created in 18 goats and stabilized using circular external fixation. After a 5-day latency period, 4 weeks of limb distraction began to obtain a 2-cm gap; this was followed by 8 weeks of regenerate consolidation. The goats were divided into 3 groups: static (rigid) fixation (SF, n = 6); dynamic fixation (DF, n = 6), consisting of continuous micromotion using dynamizers; and reverse dynamization (RD, n = 6), consisting of initial micromotion during the distraction period using dynamizers followed by rigid fixation during the consolidation period. Healing was assessed using radiographs, micro-computed tomography, histological analysis, and mechanical testing. Radiographic evaluation showed earlier regenerate formation in the DF and RD groups compared with the SF group. After the distraction and consolidation periods were completed, the regenerate formed under the conditions of RD had less trabeculation, higher bone mineral density, and smaller total and bone volumes, and were stronger in torsion compared with the SF and DF groups. This appearance is characteristic of advanced remodeling, returning closest to the values of intact bone. The DF group also had evidence of an interzone (radiolucent fibrous zone) at the end of the consolidation period. Application of the reverse dynamization regimen during distraction osteogenesis accelerated formation, maturation, and remodeling of regenerate bone. The findings of this study have important implications in the clinical setting, as reverse dynamization may lead to shorter treatment times and potentially lower prevalence of complications for patients needing distraction osteogenesis.

BACKGROUND AND PURPOSE: Intramedullary bone-lengthening nails have become increasingly popular. The 2 most used and successful nails are the FITBONE and the PRECICE nails. Uniform reporting is lacking on complications of intramedullary bone-lengthening nails. The purpose was therefore to assess and categorize the complications of lower limb bone-lengthening nails and investigate risk factors. PATIENTS AND METHODS: We performed a retrospective review of patients operated on with intramedullary lengthening nails at 2 hospitals. We included only lower limb lengthening with FITBONE and PRECICE nails. Recorded patient data was patient demographics, nail information, and any complication. Complications were graded according to severity and origin classification. Complication risk factors were assessed with modified Poisson regression. RESULTS: 314 segments in 257 patients were included. The FITBONE nail was predominantly used (75%), and most of the lengthenings were performed in the femur (80%). 53% of the patients had complications. 269 complications were identified in 175 segments (144 patients). Device-related complications were most frequent (0.3 complications/segment), followed by joint complications (0.2 complications/segment). An increased relative risk was found for complications in the tibia compared with the femur and for age groups above 30 years compared with the 10-19 years group. CONCLUSION: Complications with intramedullary bone lengthening nails were more frequent than has previously been reported, with 53% of patients sustaining a complication. Future studies need to document the complications meticulously so that the true risk can be established.

BACKGROUND: In surgical specialties like orthopaedics, documenting the surgery performed involves applying the appropriate current procedural terminology (CPT) code(s). For limb reconstruction surgeons, the wide-ranging types of surgeries and rapid evolution of the field create a variety of factors making it difficult to code the procedures. We sought to (1) assess whether appropriate limb reconstruction codes currently exist and (2) determine whether there is agreement among experienced pediatric orthopaedic surgeons when applying these codes to similar cases. METHODS: A REDCAP survey comprised of 10 common pediatric limb reconstruction cases was sent to experienced pediatric limb reconstruction surgeons in the United States. Based on the description of each case, the surgeons were asked to code the cases as they usually would in their practice. There were no limitations regarding the number or the types of codes each surgeon could choose to apply to the case. Nine additional demographic and general coding questions were asked to gauge the responding surgeon's coding experience. RESULTS: Survey participants used various codes for each case, ranging from only 1 code to a maximum of 9 codes to describe a single case. The average number of codes per case ranged from 1.2 to 3.6, with an average of 2.5 among all 10 cases. The total number of unique codes provided by the respondents for each case ranged from 5 to 20. Only 3 of the 10 cases had an agreement >75% for any single code, and only 2 of the 10 cases had >50% agreement on any combination of 2 codes. CONCLUSIONS: There are dramatic variations in coding methods among pediatric orthopaedic limb reconstruction surgeons. This information highlights the need to improve the current CPT coding landscape. Possible solutions include developing new codes that better represent the work done, developing standardized guidelines with the existing codes to decrease variation, and improving CPT coding education by developing limb reconstruction coding "champions." LEVEL OF EVIDENCE: Level V.

INTRODUCTION: Postoperative pneumonia increases the risk of postsurgical mortality, making it a serious healthcare-associated complication. Children with preoperative neuromuscular impairments have a higher risk of postoperative pneumonia. Obesity is also a risk factor for postoperative pulmonary complications, including pneumonia. Moreover, obesity is increasingly prevalent among children living with a neurological diagnosis. Whether obesity increases the risk of postoperative pneumonia among children with neurologic diseases remains largely unknown. Therefore, we assessed the risk of postoperative pneumonia among children with neurologic diagnoses based on their obesity status. METHODS: We analyzed a retrospective cohort of children ≤18 years from the National Surgical Quality Improvement Program (2012-2019) database who underwent inpatient orthopedic surgery. We used Cox proportional regression model to estimate the hazard ratio for the association between neurologic disorders and postoperative pneumonia. In addition, we included an interaction term between body mass index and neurologic disorders to evaluate the moderating effect of obesity status and then performed stratified analyses to compare the magnitude of hazard ratios across body mass index subgroups. RESULTS: A total of 60 745 children underwent inpatient orthopedic surgery during the study period, of whom 43.6% were healthy weight and 30.8% overweight/obese. The median age was 13 years (Interquartile range: 8-15). The incidence of postoperative pneumonia was higher among healthy weight patients with neurologic disorders than healthy weight patients without any neurologic disorders [Hazard ratio: 3.55 vs. 0.34]. Furthermore, the association between neurologic disorders and postoperative pneumonia was strongest among overweight patients than healthy weight or obese patients [Hazard ratio:11.88 vs. 9.45 vs. 4.40]. This observation was consistent across the various neurologic disorders analyzed. CONCLUSION: Childhood obesity buffered the association between neurologic disorders and postoperative pneumonia, consistent with an 'obesity paradox'. Further research exploring the underlying mechanisms for the obesity paradox in children with neurologic disorders is warranted.

Background. Lower extremity injuries in the pediatric population that are associated with Gustillo 3B/3C fractures require special consideration. Limb salvage should be attempted in the pediatric patient if at all possible, and oftentimes the soft tissue defect that is present over the bony fracture is substantial. The traditional algorithm used in the management of Gustillo 3B/3C fractures in plastic surgery, referred to as the reconstructive ladder, would recommend flap reconstruction with free tissue transfer in most cases because regional options are often unavailable or do not provide adequate coverage. Free tissue transfer procedures are extensive and necessitate a donor site; they often require multiple procedures and subsequent revisions. Furthermore, when concomitant injuries or medical conditions are present, a patient may not be an appropriate candidate for a free flap. Another option, however, does exist for the pediatric patient with a significant lower extremity injury that is often overlooked by the plastic surgeon. Several articles in the orthopedic literature describe the utility of temporary limb deformation to allow for soft tissue closure, with gradual correction of the bony deformity over time. Although the healing process for these procedures take several months, there is no need for extensive soft tissue reconstruction and the ultimate result is a leg that is functional with adequate coverage. This article reports a case where this type of bone and soft tissue reconstruction was performed in a patient with an excellent overall outcome. This technique could be useful in select cases as an option in pediatric lower extremity reconstruction.
RESUMO
Introduction: Limb lengthening is increasingly accomplished by internal lengthening nails. Previous versions of the magnetic lengthening nails made from titanium alloy allowed limited weight-bearing. In contrast, the newer nails made of stainless steel allow increased weight-bearing. An objective comparison of the rate of healing of the regenerate bone based on the weight-bearing capabilities of these two types of lengthening nails has not been evaluated. The hypothesis for the study is that earlier commencement of full weight-bearing in patients treated with the stainless steel STRYDE® nail will lead to faster healing of the regenerate bone during intramedullary limb lengthening compared with those treated with the titanium PRECICE® nail. Materials and methods: Thirty patients, divided into two groups of 15 each, underwent antegrade intramedullary lengthening of the femur using a magnetic lengthening nail between May 2017 and November 2020. The pixel value ratio (PVR) obtained from serial digital radiographs was used to quantitatively determine the regenerate bone's mineralisation rate. We compared the rate of healing of the regenerate bone in both groups of patients using the PVR. Results: Patients treated with the STRYDE® nail achieved unassisted full weight-bearing significantly earlier than patients treated with the PRECICE® nail (12 weeks vs 17 weeks for STRYDE® and PRECICE® nail-lengthened patients, respectively, p = 0.003). There was no difference in the PVR between both groups of patients at the time of full weight-bearing (p = 0.0857). However, patients treated with the STRYDE® nail attained a PVR of 1 significantly earlier than those treated with the PRECICE® nail (0.0317). Conclusion: The STRYDE® nail provides an earlier return of function and full weight-bearing compared with the PRECICE® lengthening nail. Earlier commencement of weight-bearing ambulation leads to more rapid mineralisation of the regenerate bone in patients undergoing intramedullary limb lengthening.

RESUMO
BACKGROUND: Intramedullary lengthening nails have shown excellent short-term results. The FITBONE and the PRECICE nail are the two most commonly used intramedullary lengthening nails. The manufacturer of each nail recommends the removal of the implant after the completion of the treatment. Despite the need for removal of each nail, the authors are not aware of any prior publications documenting the results of standard intramedullary lengthening nail removal. Therefore, the aim of this study was to examine the intraoperative and postoperative complications of elective intramedullary lengthening nail removals. MATERIALS AND METHODS: We performed a retrospective chart review of patients operated with intramedullary lengthening nails at two limb reconstruction centres (one in the United States, and the second in Denmark). Data retrieved from the patient charts included patient demographics, nail information and any complications occurring at or after nail removal. Only lower limb lengthening with FITBONE and PRECICE or STRYDE nails that had an elective nail removal was included. RESULT: A total of 271 elective nail removals were included in the study. Complications occurred during 3% of the nail removals and in 13% after nail removal. There were 18 reported cases with postoperative knee pain. All these patients had nail removal through the knee joint, representing 8% of the retrograde femur nail removals and 7% of the tibia nail removals. Four postoperative fractures occurred, of which two needed surgery. Eleven percent of femur removals and 26% of tibial removals sustained a complication. CONCLUSION AND CLINICAL SIGNIFICANCE: This study emphasises the importance of adequate follow-up of the bone lengthening patient even after the nail has been removed. It also shows that the recommended removal of the intramedullary nail (IMN) lengthening nails must be included in studies reporting on the overall risks of complications using bone lengthening nails.

RESUMO
AIMS: Limb-lengthening nails have largely replaced external fixation in limb-lengthening and reconstructive surgery. However, the adverse events and high prevalence of radiological changes recently noted with the STRYDE lengthening nail have raised concerns about the use of internal lengthening nails. The aim of this study was to compare the prevalence of radiological bone abnormalities between STRYDE, PRECICE, and FITBONE nails prior to nail removal. METHODS: This was a retrospective case series from three centres. Patients were included if they had either of the three limb-lengthening nails (STYDE, PRECICE, or FITBONE) removed. Standard orthogonal radiographs immediately prior to nail removal were examined for bone abnormalities at the junction of the telescoping nail parts. RESULTS: In total, 306 patients (168 male, 138 female) had 366 limb-lengthening nails removed. The mean time from nail insertion to radiological evaluation was 434 days (36 to 3,015). Overall, 77% of STRYDE nails (20/26) had bone abnormalities at the interface compared with only 2% of FITBONE (4/242) and 1% of PRECICE nails (1/98; p < 0.001). Focal osteolysis in conjunction with periosteal reaction at the telescoping interface was only observed in STRYDE nails. CONCLUSION: Bone abnormalities at the interface of telescoping nail parts were seen in the majority of STRYDE nails, but only very rarely with FITBONE or PRECICE nails. We conclude that the low prevalence of radiological changes at the junctional interface of 242 FITBONE and 98 PRECICE nails at the time of nail removal does not warrant clinical concerns.

BACKGROUND: Lengthening of long bones by distraction osteogenesis is now possible using intramedullary lengthening nails. Constraints of bone size, medullary canal obstruction, and the presence of an open physis are contraindications in skeletally immature patients. We present a technique describing the "off-label" use of a magnetic lengthening nail placed extramedullary and in retrograde manner, for lengthening of the femur in skeletally immature patients. METHODS: A retrospective review of 5 skeletally immature patients with significant length discrepancy of the femur are presented along with a description of the surgical technique. Data collected included age, sex, date of surgery, diagnosis, presence of associated deformities, the magnitude of length discrepancy, the amount of length gained, the amount of time to achieve full weight-bearing, the time to hardware removal, and any complications. RESULTS: There were 5 patients (3 females). The mean age was 7.2±2.7 years (4 to 10 y). The mean limb length discrepancy was 6.5±3.7 cm (3.5 to 11 cm). A mean length of 3.46±0.4 cm (3.1 to 4 cm) was achieved which represents 12.9±1.8% (10.32 to 13.47%) of the bone length. The time taken to achieve full weight-bearing ambulation was 89.2±19.3 days (60 to 109 d) or 12.7 weeks. All hardware was removed 247.6±215.6 days (99 to 628 d) after surgery. Patients were followed up for a mean duration of 19.2 months (11 to 30 mo). No supplemental fixation was required and no complications were noted. Acute deformity correction was also performed at the time of surgery in 2 patients who had distal femur valgus deformity. CONCLUSIONS: Retrograde extramedullary lengthening of the femur is an option that should be considered for limb length equalization in skeletally immature patients. It avoids the inconvenience of external fixation and can be used to simultaneously correct deformities of the distal femur. Although the total amount of length gained is modest, we believe it is a promising limb lengthening technique that merits further investigation. LEVEL OF EVIDENCE: Level III.

BACKGROUND: The Gait Outcomes Assessment List for children with Lower Limb Difference (GOAL-LD) is a patient and parent-reported outcome measure that incorporates the framework of the International Classification of Functioning, Disability, and Health. This prospective multicenter cohort study evaluates the validity and reliability of the GOAL-LD and the differences between parent and adolescent report. METHOD: One hundred thirty-seven pediatric patients aged over 5 years attending limb reconstruction clinics at the participating sites were assessed at baseline, and a self-selected cohort also completed an assessment 2 to 6 weeks later. Construct and criterion validity were assessed by comparing GOAL-LD scores with a measure of limb deformity complexity (LLRS-AIM) and the Pediatric Outcomes Data Collection Instrument, using Spearman correlation coefficients. Face and content validity were determined through ratings of item importance. Test-retest reliability was reported as an intraclass correlation coefficient and internal consistency using Cronbach α. Adolescent reports were compared with their parents using paired t tests. RESULTS: The GOAL-LD demonstrated a moderate negative correlation with the LLRS-AIM (r=-0.40, P<0.001) and was able to discriminate between deformity complexity groups as defined by the LLRS-AIM (χ2=11.43, P=0.022). Internal consistency was high across all domains (α≥0.68 to 0.97). Like domains of the Pediatric Outcomes Data Collection Instrument and the GOAL-LD were well correlated. Parents reported a lower total GOAL-LD score when compared with adolescents (mean difference 3.04; SE 1.06; 95% confidence interval, 0.92-5.16; P<0.01); however this difference was only significant for body image and self-esteem (Domain F) and gait appearance (Domain D). Test-retest reliability remained high over the study period (intraclass correlation coefficient 0.85; SE 0.03; 95% confidence interval, 0.77-0.91). CONCLUSIONS: The GOAL-LD is a valid and reliable self and parent-reported outcome measure for children with lower limb difference. Parents report a lower level of function and attribute a higher importance to items when compared with their children. The GOAL-LD helps to communicate parent and child perspectives on their function and priorities and therefore has the capacity to facilitate family centered treatment planning and care. LEVEL OF EVIDENCE: Level II-diagnostic. Prospective cross-sectional and a longitudinal cohort design.
RESUMO
BACKGROUND: Lower limb deformities include conditions such as leg length discrepancy, lower limb deficiency and associated angular and rotational deformities of the hips, knees, ankles and feet. Children with lower limb deformities often have physical limitations due to gait irregularities and pain. The differences in the appearance and function of their lower limbs can discourage participation in social, recreational and leisure activities, which may result in behavioural, emotional, psychological and social adjustment problems. The health-related quality of life (HRQL) of these children is often impacted due to the factors discussed above, as well as by the complex surgical procedures. Surgical treatment options for limb deformities in children vary from limb lengthening and reconstruction to amputation. The lack of evidence demonstrating superiority of either treatment options and their effect on HRQL limits the ability of healthcare providers to counsel families on the best evidence-based treatment option for them. This manuscript describes the international qualitative study which guided the development of a new patient-reported outcome measure (PROM). Individual semi-structured face-to-face interviews with children with lower limb deformities and their parents were conducted at five sites: Canada (2 sites), Ethiopia, India and the USA. RESULTS: Seventy-nine interviews were conducted at five international sites. Five main themes emerged from the qualitative interviews and formed the basis of the conceptual framework. These themes were: 1) appearance, 2) physical health, 3) psychological health 4) school and 5) social health. CONCLUSIONS: Lower limb deformities have a substantial impact on the HRQL of children. The concepts of interest identified in our study were similar across children from all countries. The conceptual framework guided the development of outcome scales specific to these patients. The information about the impact of various treatment options on the HRQL of children with lower limb deformities, collected using this new PROM, could be used to inform parents and children about outcomes (physical, social, psychological) associated with specific treatment options. This information could supplement other objective outcome information (e.g., complication rates, how the leg will look, etc.) to help families to come to a more informed decision on a child's course of treatment.
RESUMO
CASE: We present a case of an 18-month-old child with early-onset scoliosis in the setting of spinal muscular atrophy (SMA) type 1 whose rapidly progressive scoliosis is successfully managed with magnetic growing rods, the youngest age of implantation in a patient with SMA we are currently aware of. Technical challenges, complications, and outcome are described in this case presentation. CONCLUSION: Patients with SMA type 1 and early-onset scoliosis can be managed with growing-rod constructs given dramatic improvements in medical care that have expanded life expectancy.
