Abstract
Pediatric femur fractures in children aged 5 to 11 years are typically classified as length-stable versus length-unstable. For length-stable fracture patterns, there is frequent consensus among pediatric orthopaedic specialists regarding the appropriateness of flexible intramedullary nails, submuscular plates (SMP), or lateral-entry rigid intramedullary nails (LE-RIMN). With length-unstable fracture patterns, however, the decision is more complex. Age, weight, fracture pattern, fracture location, surgical technique, surgeon experience, several implant-specific details, and additional factors are all important when choosing between flexible intramedullary nail, SMP, and LE-RIMN. These familiar methods of fixation may all be supported by conflicting and sometimes heterogeneous data. When planning to treat length-unstable fractures in young children, surgeons should understand evidence-based details associated with each implant and how each patient-specific scenario affects perioperative decisions.

Abstract
BACKGROUND Though the importance of level 1 pediatric trauma has repeatedly been shown to lessen both morbidity and mortality in critically injured children, these same tertiary referral centers also receive numerous transfers of patients with less severe injuries. This not only leads to increased costs and use of limited facility resources but, oftentimes, frustration and unnecessary expense to those families for whom transfer was avoidable. Prior work has demonstrated that half of all inappropriate pediatric interfacility transfers are due to orthopedic injuries. This study aims to evaluate the incidence of inappropriate transfers of pediatric patients with isolated orthopedic injuries to a pediatric level 1 trauma center and identify factors associated with such transfers. METHODS All patients transferred to a large metropolitan level 1 pediatric trauma center for isolated orthopedic injuries over a 6-year period were retrospectively evaluated. Medical records were reviewed for demographic and injury data, including age, gender, race, social deprivation index, insurance status, location of transferring institution, timing of transfer, and availability of orthopedic on-call coverage at transferring institution. The transfer was deemed to be appropriate if the patient required a sedated reduction, was admitted to the hospital, or was taken to the operating room within 24 hours of transfer. Regression analysis was reviewed for each of the demographic, patient, and transfer characteristics in an attempt to isolate those associated with inappropriate transfer. RESULTS In all, 437 transfers occurred during the study period. Of these, 112 (26%) were deemed inappropriate. 4% of patients transferred for orthopedic injuries did not receive an orthopedic consult following the transfer. Non-white patients were more likely than white patients to be transferred inappropriately (34.01% vs. 21.58%, P=0.009 ). No other demographic characteristic was predictive of inappropriate transfer. There was no difference in the rate of appropriate transfer between patients with private insurance versus government-funded, self-paying, or uninsured patients. The timing of transfer (night vs. day and weekday vs. weekend) did not affect the appropriateness of transfer. Facilities with orthopaedic on-call coverage were more likely to inappropriately transfer patients than those without (26.6% vs. 23.4%, P<0.001 ). CONCLUSION A quarter of patients transferred for isolated orthopaedic injuries were inappropriately transferred. Unlike studies published in adult literature, the timing of transfer (overnight and weekend) and the insurance status of the patient did not appear to play a role in the appropriateness of transfer. Inappropriate and unnecessary trauma transfers create a significant burden on tertiary referral centers. Raising awareness of the high incidence of unnecessary transfers coupled with enhanced education of outside emergency medicine providers may result in better stewardship of health care resources, limit delays in patient care, and reduce strain on both the health care delivery system and the families of injured children.

Abstract
BACKGROUND As the incidence of childhood obesity continues to rise, so too does the number of obese children who undergo foot surgery. As the childhood obesity epidemic rolls on, pediatric orthopaedic surgeons will encounter obese patients with even greater frequency. Therefore, a comprehensive understanding of the risks associated with obesity is valuable to maximize patient safety. The purpose of this study is to retrospectively evaluate the relationship between obesity and postoperative outcomes in patients undergoing pediatric foot surgery across multiple institutions using a large national database. METHODS Pediatric patients who had undergone foot surgery were retrospectively identified using the American College of Surgeons 2012-2017 Pediatric National Surgical Quality Improvement (ACS-NSQIP-Pediatric) database by cross-referencing reconstructive foot-specific CPT codes with ICD-9/ICD-10 diagnosis codes. Center for Disease Control BMI-to-age growth charts were used to stratify patients into normal-weight and obese cohorts. Univariate and multivariate analyses were performed to describe and assess outcomes in obese compared with normal-weight patients. RESULTS Of the 3924 patients identified, 1063 (27.1%) were obese. Compared with normal-weight patients, obese patients were more often male (64.7% vs. 58.7%; P =0.001) and taller (56.3 vs. 51.3 inches; P <0.001). Obese patients had significantly higher rates of overall postoperative complications (3.01% vs. 1.32%; P =0.001) and wound dehiscence (1.41% vs. 0.59%; P =0.039). Multivariate analysis found that obesity was an independent predictor of both wound dehiscence [adjusted odds ratio (OR)=2.16; 95% CI=1.05-4.50; P =0.037] and surgical site infection (adjusted OR=3.03; 95% CI=1.39-6.61; P =0.005). Subgroup analysis of patients undergoing clubfoot capsular release procedures identified that obese patients had a higher rate of wound dehiscence (3.39% vs. 0.51%; P =0.039) compared with normal-weight patients. In multivariate analysis, obesity was an independent predictor of dehiscence (adjusted OR=5.71; 95% CI=1.46-22.31; P =0.012) in this procedure group. There were no differences in complication rates between obese and normal-weight patients in a subgroup analysis of tarsal coalition procedures or clubfoot tibialis anterior tendon transfer procedures. CONCLUSION Obese children undergoing foot surgery had higher overall complication rates, wound complications, and surgical site infections compared with children of normal weight. As the incidence of childhood obesity continues to rise, this information may be useful in assessing and discussing surgical risks with patients and their families. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Triplane fractures are rare enough that large homogeneous series to support management decisions are lacking. During initial evaluation, the addition of computed tomography (CT) to conventional X-rays (XR) does not always alter the patient's clinical course. Therefore, routine use of CT is controversial. This study aims to: (1) clarify quantitative relationships between articular displacement measured on XR versus CT and (2) identify whether metaphyseal displacement on the lateral XR predicts clinically relevant articular displacement on a CT scan. METHODS A 10-year retrospective review of consecutive triplane fractures was performed at a level 1 pediatric trauma center. Maximum articular and metaphyseal displacement were recorded from XR and CT. Quantitative relationships between XR and CT measurements were compared among imaging modalities and radiographically operative versus nonoperative fractures. RESULTS Eighty-seven patients met the inclusion criteria. XR underestimated articular displacement by 229% in the sagittal plane (1 mm on XR vs 3.3 mm on CT; P < 0.05) and 17% in the coronal plane (2.3 mm on XR vs 2.7 mm on CT; P < 0.05). XR underestimated articular step-off by 184% in the coronal plane and 177% in the sagittal plane ( P < 0.05). CT measurements more often differentiated patients who did or did not undergo surgery at our institution. Metaphyseal displacement was significantly higher in patients with traditionally operative articular displacement (≥2.5 mm on CT) versus those with articular displacement below traditionally operative thresholds (2.4 vs 0.9 mm, P = 0.001). Sixty patients had metaphyseal displacement >1 mm on the lateral XR, of whom 56 had surgical-magnitude articular displacement (≥2.5 mm) on CT (positive predictive value = 94%). CONCLUSIONS Conventional radiographs underestimate the true articular displacement of triplane fractures. Surgical-magnitude articular step-off is rare, and the largest articular gap is usually visualized on the axial CT image. Metaphyseal displacement >1 mm, which is easily measured on a lateral XR, is strongly predictive of clinically relevant articular displacement on CT. This radiographic finding should prompt advanced imaging before proceeding with nonoperative management. LEVEL OF EVIDENCE Level III.

Abstract
Pediatric medial malleolus fractures are commonly Salter-Harris (SH) type III or IV fractures of the distal tibia and are associated with a risk of physeal bar formation and subsequent growth disturbance. The purpose of this study was to determine the incidence of physeal bar formation following pediatric medial malleolus fracture and evaluate for patient and fracture characteristics predictive of physeal bar formation. Seventy-eight consecutive pediatric patients during a 6-year period who had either an isolated medial malleolar or a bimalleolar ankle fracture were retrospectively reviewed. Forty-one of 78 patients had greater than 3 months of radiographic follow-up and comprised the study population. Medical records were reviewed for demographic information, mechanism of injury, treatment, and need for further surgery. Radiographs were reviewed to assess for initial fracture displacement, adequacy of fracture reduction, SH type, percentage of the physeal disruption from the fracture, and physeal bar formation. Twenty-two of 41 patients (53.7%) developed a physeal bar. The mean time to diagnosis of physeal bar was 4.9 months (range, 1.6-11.8 months). Twenty-seven percent (6 of 22) of bars were diagnosed at greater than 6 months from injury. Adequacy of reduction was predictive of physeal bar formation, although all patients were reduced to within 2 mm. The mean residual displacement of patients with a bar was 1.2 mm compared with 0.8 mm for those without a bar (P=.03). Because the bar formation rate is greater than 50% on radiographs, routine radiographic assessment of all pediatric medial malleolar fractures should continue for at least 12 months after injury.

Abstract
Even under ideal circumstances, recurrence of infantile clubfoot deformity following the Ponseti method of treatment is to be expected to occur in as many as 20% of patients. When encountered early in childhood, these recurrences are usually amenable to further casting and limited surgery. Creation of a plantigrade foot, however, becomes much more challenging when recurrences present during adolescence and early adulthood. Because of the stiffer nature of these deformities in older patients, the fact that they are often more severe because of varying lengths of neglect, and the often deleterious effects of prior intra-articular surgeries on joint health, a principled approach is recommended for both the assessment of these feet and development of an appropriate treatment plan. In doing so, the surgeon can select the combination of nonsurgical and surgical interventions that allows for as little surgery as possible to create a plantigrade foot while maintaining any motion that is present before treatment. Although no single algorithmic approach can be applied to the variety of deformities and potentially complicating factors that are encountered in treating such patients, an understanding of the utility of preoperative casting, gradual and acute corrective techniques, and the importance of identifying and mitigating deforming forces and tendon imbalance can greatly optimize outcomes.

Abstract
Tibialis anterior tendon (TAT) transfer to the lateral cuneiform is commonly utilized to treat dynamic supination for relapsed clubfoot deformity. Traditional suture button fixation (SBF) may lead to skin necrosis at the button/skin interface. While interference screw fixation (ISF) would mitigate this concern, this fixation method has not been investigated in clubfoot patients. This study aims to investigate the performance of ISF versus SBF for TAT transfer in a cadaveric model. Ten matched pairs of cadaveric feet were obtained. One of each matched specimen underwent TAT transfer to the lateral cuneiform using ISF and the other underwent TAT transfer using SBF. For each ISF specimen, the tension of the transferred TAT required to bring the ankle to neutral was measured. This tension was then applied to both matched specimens using an MTS machine. Tension dissipation was measured after a 20-minute interval. In specimens with SBF, a load cell was positioned between the plantar skin and suture button to determine plantar skin pressure at the time of initial tension application. Average tension necessary to achieve neutral dorsiflexion was 49.4 N. Average tension dissipation after 20 min was significantly less in the IFS group (20 N versus 23.6 N, P = 0.02). No fixation failures occurred in either group. Average plantar foot skin pressure was 196.5 mmHg at initial tension application, exceeding thresholds for tissue ischemia. ISF allows for tendon tensioning at forces beyond those expected to result in skin necrosis with SBF with less dissipation of tension over time.

Abstract
BACKGROUND Because of the rarity of dysplasia epiphysealis hemimelica (DEH), little is known about the relationship between disease classification and clinical symptoms or patient outcomes. This studies therefore aims to characterize DEH of the lower extremity and correlate radiographic classification to presenting symptomatology and need for surgical intervention. METHODS A multi-center, retrospective review of all patients with DEH of the lower extremity over a 47-year period was conducted. Demographic data, presenting complaints, treatments, and symptoms at final follow-up were recorded. Radiographs were reviewed to classify lesions using the Universal Classification System for Osteochondromas (UCSO) and document the presence of solitary or multiple lesions within the involved joint. Correlative statistics were used to determine whether presenting complaints, lesion location or radiographic classification predicted the need for surgery or a pain-free outcome. RESULTS Twenty-eight patients met inclusion criteria with an average age at presentation of 7.8 years. The ankle was the most commonly affected joint with 20/28 patients (71%) having lesions of the talus, distal tibia, or distal fibula. Patients with chief complaints of pain were more likely to undergo surgery than those with complaints of a mass or deformity ( P =0.03). Ankle lesions were more likely to be managed operatively than those of the hip or knee ( P =0.018) and all 12 patients with talar lesions underwent surgery. Neither the number of lesions nor lesion classification was predictive of surgical intervention or a pain-free outcome after surgery. Patients presenting with pain were more likely to have a pain-free outcome (11/14 patients) after surgery ( P =0.023) whereas all patients presenting with deformity who underwent surgery had pain at final follow-up. CONCLUSIONS Although no single radiographic characteristic of DEH was predictive of surgical intervention or outcome, painful lesions of the ankle, and lesions of the talus were more likely to be managed operatively. Although surgery does not always result in a pain-free outcome, the operative management of painful lesions was more likely to provide a pain-free outcome than surgery for deformity or a mass.

Abstract
BACKGROUND There is no uniform classification system for traumatic upper cervical spine injuries in children. This study assesses the reliability and reproducibility of the AO Upper Cervical Spine Classification System (UCCS), which was developed and validated in adults, to children. METHODS Twenty-six patients under 18 years old with operative and nonoperative upper cervical injuries, defined as from the occipital condyle to the C2-C3 joint, were identified from 2000 to 2018. Inclusion criteria included the availability of computed tomography and magnetic resonance imaging at the time of injury. Patients with significant comorbidities were excluded. Each case was reviewed by a single senior surgeon to determine eligibility. Educational videos, schematics describing the UCCS, and imaging from 26 cases were sent to 9 pediatric orthopaedic surgeons. The surgeons classified each case into 3 categories: A, B, and C. Inter-rater reliability was assessed for the initial reading across all 9 raters by Fleiss's kappa coefficient (kF) along with 95% confidence intervals. One month later, the surgeons repeated the classification, and intra-rater reliability was calculated. All images were de-identified and randomized for each read independently. Intra-rater reproducibility across both reads was assessed using Fleiss's kappa. Interpretations for reliability estimates were based on Landis and Koch (1977): 0 to 0.2, slight; 0.2 to 0.4, fair; 0.4 to 0.6, moderate; 0.6 to 0.8, substantial; and >0.8, almost perfect agreement. RESULTS Twenty-six cases were read by 9 raters twice. Sub-classification agreement was moderate to substantial with α κ estimates from 0.55 for the first read and 0.70 for the second read. Inter-rater agreement was moderate (kF 0.56 to 0.58) with respect to fracture location and fair (kF 0.24 to 0.3) with respect to primary classification (A, B, and C). Krippendorff's alpha for intra-rater reliability overall sub-classifications ranged from 0.41 to 0.88, with 0.75 overall raters. CONCLUSION Traumatic upper cervical injuries are rare in the pediatric population. A uniform classification system can be vital to guide diagnosis and treatment. This study is the first to evaluate the use of the UCCS in the pediatric population. While moderate to substantial agreement was found, limitations to applying the UCCS to the pediatric population exist, and thus the UCCS can be considered a starting point for developing a pediatric classification.

Abstract
BACKGROUND Though flatness of the talar dome (TD) is a potential consequence of operative and nonoperative clubfoot management, the functional impact of this deformity is not well understood. This study analyzes the relationship between TD morphology and ankle function at skeletal maturity in patients treated for idiopathic clubfoot during infancy. METHODS 33 skeletally mature patients (average age 17.9 years) with 48 idiopathic clubfeet were identified. Weightbearing radiographs, gait analysis, and patient-reported outcomes using the Pediatric Orthopaedic Data Collection Instrument (PODCI) were obtained. Radius of curvature (ROC) of the TD and tibial plafond were measured along with other parameters of talar and calcaneal morphology. All measurements were correlated to PODCI scores and gait analysis data. RESULTS Patients demonstrated marked variability in ROC of the TD (mean 30.8 mm, SD 13.6 mm), TD radius to talar length (R/L) ratio (mean 0.56, SD 0.28), opening angle of the TD (alpha angle) (mean 89.6°, SD 28.4°), and tibiotalar incongruity index (mean 0.18, SD 0.16). Increased tibiotalar incongruity index correlated with decreased maximum plantar flexion (r = ‒0.325, P = .02). A less acute alpha angle of the talar dome correlated with increased maximum ankle power generation (r = 0.321, P = .03) as did increased length of the talar neck (r = 0.358, P = .013). Increased tibiotalar incongruity index correlated negatively with PODCI global function domain scores (r = ‒0.490, P = .04; r = ‒0.381, P = .03, respectively), whereas length of the talar body correlated with higher global function scores (r = 0.376, P = .03) and lower pain scores (r = 0.350, P = .046). CONCLUSION At skeletal maturity, flattening of the talar dome and tibiotalar incongruity on plain radiographs correlate modestly with gait changes, whereas tibiotalar incongruity and length of the talar body, not flatness of the talar dome, correlate with decreased patient-reported outcome scores.

BACKGROUND While the transfer of the tibialis anterior tendon (TAT) to the lateral cuneiform (LC) following serial casting has been used for nearly 60 years to treat relapsed clubfoot deformity, modern methods of tendon fixation remain largely unstudied. Interference screw fixation represents an alternative strategy that obviates concerns of plantar foot skin pressure-induced necrosis and proper tendon tensioning associated with button suspensory fixation. A better understanding of LC morphology in young children is a necessary first step in assessing the viability of this fixation technique. Therefore, the purpose of this investigation is to define LC morphology and TAT width in children aged 3 to 6 years. METHODS A retrospective radiographic review of 40 healthy pediatric feet aged 3 to 6 years who had either magnetic resonance imaging or computed tomography scans was performed at a single pediatric hospital. The length, width, and height of only the ossified portion of the LC were measured digitally using sagittal, coronal, and axial imaging. In addition, the maximal cross-sectional diameter of the TAT was measured at the level of the tibiotalar joint. RESULTS The average ossified LC width ranged from 8.5 mm in the 3-year-old cohort to 10.3 mm in 6-year-old children. Analysis of variance testing revealed no statistically significant difference in width between age groups. Average ossified LC length ranged from 13.5 mm in the 3-year-old cohort to 18.3 mm in 6-year-old children with statistically significant increases in age groups separated by 2 or more years. Significant differences in LC height, volume, and TAT diameter were demonstrated after analysis of variance testing. The TAT to ossified LC width ratio ranged from 44% to 53% across age groups. CONCLUSIONS The dimensions of the LC ossification center are large enough to allow interference screw fixation in children 3 to 6 years of age. Further studies are needed to investigate interference screw fixation performance in the pediatric clubfoot population. LEVEL OF EVIDENCE Level IV.

Abstract
This study aims to identify characteristics associated with poor appointment adherence after surgical stabilization of supracondylar humerus fractures (SCHFX) in children. A retrospective review of 560 consecutive, surgically managed patients with SCHFX from 2010 to 2015 was performed. One missed follow-up appointment was classified as 'low adherence', whereas missing two or more appointments was classified as 'very low adherence'. Demographics, insurance status, estimated family income and distance from clinic were analyzed to identify differences in variables between adherent and low-adherent groups. Of 560, 121 (21.8%) missed one follow-up visit and 39/560 (7.1%) missed more than two visits. Age, gender, distance traveled, insurance status and primary language were nonpredictive. Estimated income <$50 000 was associated with a >200% increase in low adherence vs patients with estimated income >$50 000 (9.3 vs 3.8%; P = 0.012). African American patients had significantly lower adherence vs patients of other races (47.5 vs 19.6%; P < 0.0001). Ethnicity remained the only significant factor correlated to adherence after multivariate analysis. African Americans were three times more likely demonstrate low adherence (P = 0.0014). Ethnicity and estimated income <$50 000 were predictors of missing two or more visits. African American patients were four times more likely to miss two or more visits [odds ratio (OR), 4.17; P = 0.0026] than others; estimated income <$50 000 was associated with a two-fold increase in missing two or more visits (OR, 2.33; P = 0.035). By identifying at-risk patient populations, healthcare systems can adopt strategies to remove barriers of accessing follow-up care.

Abstract
BACKGROUND Although the negative effects of diabetes mellitus (DM) on operative outcomes in orthopaedic surgery is a well-studied topic in adults, little is known about the impact of this disease in children undergoing orthopaedic procedures. This study aims to describe the postoperative complications in pediatric orthopaedic surgery patients with DM. METHODS Pediatric patients with insulin-dependent diabetes mellitus (IDDM) and non-insulin-dependent diabetes mellitus (NIDDM) were retrospectively identified while selecting for elective orthopaedic surgery cases from the American College of Surgeons National Surgical Quality Improvement Program Pediatric (ACS-NSQIP-Pediatric) database from 2012 to 2015. Univariate and multivariate analyses were performed to describe and assess outcomes when compared with nondiabetic patients undergoing similar procedures. RESULTS Of the 17,647 patients identified, 105 (0.60%) had DM. Of those 105 patients, 68 had IDDM and 37 had NIDDM. The median age of DM patients was 13.8 years (11.9 to 15.5 y) and 37.1% of all DM patients were male. Comparing DM to non-DM patients, no significant differences were noted in the overall complications (1.4% vs. 1.9%, P>0.05) or reoperation rates (1.2% vs. 1.9%, P>0.05); however, DM patients did have a higher occurrence of unplanned readmissions (4.8% vs. 1.7%; P=0.037). Diabetic patients were statistically more likely to have an unplanned readmission with 30 days (adjusted odds ratio=3.34; 95% confidence interval=1.21-9.24, P=0.021). when comparing IDDM to NIDDM, there was no significant difference in outcomes. Comparing NIDDM to non-DM patients, there was an increased incidence of nerve injury (5.6% vs. 0.18%; P=0.023), readmission rate (11.1% vs. 1.8%; P=0.043), and reoperation rate (11.1% vs. 1%; P=0.013) in nonspinal procedures and an increased incidence of pulmonary embolism (10% vs. 0%; P=0.002) in spinal arthrodesis procedures. NIDDM predicted longer hospital stays (adjusted odds ratio=1.49; 95% confidence interval=1.04, 2.14; P=0.028) compared with nondiabetic patients in extremity deformity procedures. CONCLUSIONS The 30-day complication, reoperation, and readmission rates for NIDDM patients were higher than that of non-DM patients. Furthermore, NIDDM is a predictor of longer hospital stays while DM is a predictor of unplanned readmissions. No statistical differences were noted when comparing outcomes of NIDDM to IDDM patients.

Abstract
Despite the widespread use of the Ponseti method for treatment of clubfeet, there continue to be a significant number of patients who present with a severe, stiff clubfoot as a result of extensive intra-articular soft tissue release or lack of access to care. In such patients, circular external fixators can be utilized for deformity correction with distraction across soft tissues, joints, and osteotomies. Ilizarov or hexapod circular fixators may be utilized according to surgeon preference. Indications for soft tissue release and osteotomies to aid in correction of clubfoot deformity with Ilizarov and hexapod fixators are not standardized and are guided by patient age, joint congruity, soft tissue suppleness, and osseous deformity. Correction time varies according to clubfoot deformity severity. Following deformity correction, external fixators are left in place for several weeks to stabilize the soft tissues and allow for osteotomy healing. Complications range from relatively minor pin tract infections that resolve with oral antibiotics to tarsal tunnel syndrome, osteomyelitis, or disabling arthritis requiring revision procedures. At Scottish Rite Hospital for Children, we prefer to correct severe residual clubfoot deformity with a hexapod external fixator. Acute correction and gradual correction via distraction are considered for each segmental deformity and utilized to efficiently correct deformity while minimizing soft tissue trauma. The purpose of this article is to summarize the relevant literature related to circular external fixator treatment of recurrent clubfoot deformity and outline our approach to the segmental deformities of the foot and ankle in this patient population.

Abstract
Background Although many pediatric Monteggia fractures can be treated nonoperatively, the presence of any residual radiocapitellar subluxation following ulnar reduction mandates a more aggressive approach to restore and maintain ulnar length. In younger children, restoration and maintenance of ulna length may be achieved through intramedullary fixation of the ulnar shaft. Description A Steinmann pin or flexible intramedullary nail is introduced percutaneously through the olecranon apophysis and advanced within the medullary canal to the ulnar fracture site. If necessary, the ulnar length and alignment are then restored by either a closed reduction or open reduction. The pin or nail is advanced across the fracture site into the distal fracture fragment and then advanced to a point just proximal to the distal ulnar physis. Once restoration of normal radiocapitellar alignment is verified fluoroscopically, the pin is bent and cut outside of the skin and a cast or splint is applied. Alternatives Closed reduction and cast immobilization is a well-accepted form of treatment for a Monteggia fracture. If ulnar length and alignment along with an anatomic reduction of the radiocapitellar joint can be achieved in this fashion, surgery can be avoided, but close radiographic follow-up is recommended to assess for loss of alignment with subsequent radial-head subluxation. Open reduction and internal fixation with use of a plate-and-screw construct can achieve similar results to intramedullary fixation and should be considered for length-unstable fractures and those in which an appropriately sized intramedullary implant fails to maintain adequate ulnar alignment. If plastic deformation of the ulna is present with residual radiocapitellar subluxation following reduction of the ulnar diaphysis, consideration should be given to elongating the ulna through the fracture site with use of plate fixation in order to allow reduction of the radial head. Rationale Intramedullary fixation provides several benefits over open reduction and plate fixation for these injuries. In general, treatment can be rendered with a shorter anesthetic time, less scarring, and without the concern for symptomatic retained hardware associated with plating along the subcutaneous boarder of the ulna shaft. Expected Outcomes Compared with nonoperative treatment, intramedullary fixation of length-stable Monteggia fractures has lower rates of recurrent radial-head subluxation and loss of ulnar alignment requiring subsequent operative treatment1. If healing is achieved without residual radiocapitellar instability, good elbow function can be expected. Important Tips The entry point for the intramedullary implant should be slightly radial to the tip of the olecranon apophysis to compensate for the anatomic varus bow of the proximal aspect of the ulna.Intramedullary fixation is ideal for length-stable ulnar fractures. If a comminuted or long oblique fracture is present, an intramedullary device may not maintain ulnar length, leading to residual or recurrent radiocapitellar instability. For length-unstable fractures, therefore, a plate-and-screw construct should be considered.No more than 3 attempts should be made to pass the intramedullary implant into the distal ulnar segment by closed means in order to limit the risk of iatrogenic compartment syndrome.If anatomic alignment of the radiocapitellar joint is not achieved following an apparent anatomic reduction of the ulna, assess for plastic deformation of the ulna and consider open elongation of the ulna through the fracture site with use of plate fixation.Following fixation and radial-head reduction, immobilize the forearm in the position of maximal radiocapitellar stability (typically in supination).

Abstract
BACKGROUND Although lengthening of the lateral column through a calcaneal neck osteotomy is an integral component of flatfoot reconstruction in younger patients with flexible planovalgus deformities, concern exists as to the effect of this intra-articular osteotomy on subtalar motion. The purpose of this study was to quantify the alterations in subtalar motion following lateral column lengthening (LCL). METHODS The subtalar motion of 14 fresh-frozen cadaveric feet was assessed using a 3-dimensional motion capture system and materials testing system (MTS). Following potting of the tibia and calcaneus, optic markers were placed into the tibia, calcaneus, and talus. The MTS was used to apply a rotational force across the subtalar joint to a torque of 5 Nm. Abduction/adduction, supination/pronation, and plantarflexion/dorsiflexion about the talus were recorded. Specimens then underwent LCL via a calcaneal neck osteotomy, which was maintained with a 12-mm porous titanium wedge. Repeat subtalar motion analysis was performed and compared to pre-LCL motion using a paired t test. RESULTS No statistically significant differences in subtalar abduction/adduction (10.9 vs 11.8 degrees, P = .48), supination/pronation (3.5 vs 2.7 degrees, P = .31), or plantarflexion/dorsiflexion (1.6 vs 1.0 degrees, P = .10) were identified following LCL. CONCLUSION No significant changes in subtalar motion were observed following lateral column lengthening in this biomechanical cadaveric study. CLINICAL RELEVANCE Although these findings do not obviate concerns of clinical subtalar stiffness following lateral column lengthening for planovalgus deformity correction, they suggest that diminished postoperative subtalar motion, when it occurs, may be due to soft tissue scarring rather than alterations of joint anatomy.

Abstract
PURPOSE This article prospectively examines the functional outcome measures following management of vascular insult secondary to paediatric supracondylar humerus fractures (SCHFX) using validated outcome measures. METHODS The three-year, prospective, IRB-approved study consecutively enrolled operative SCHFX patients. Clinical data included presence and symmetry of the radial pulse in injured and uninjured extremities, Doppler examination of non-palpable (NP) pulses and perfusion status of the hand. Pediatric Outcomes Data Collection Instruments (PODCI) and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) Measures were used to assess functional outcome at final follow-up. Multiple regression analysis was used to determine the relationship between the presence of a vascular abnormality and functional outcome while controlling for other injury parameters. RESULTS A total of 146/752 enrolled patients (mean age 6.8 years; range 2 years to 13 years) completed functional outcome measures at final follow-up. Of these, 20 (14%) patients had abnormal vascular exams at presentation: nine (6%) with palpable asymmetric pulse and 11 (7.5%) with NP pulse. Of those with NP pulses, nine/11 (6%) were Dopplerable and two (1.5%) lacked identifiable Doppler signal. Patients with a symmetric, palpable pulse demonstrated better PODCI pain and comfort scores (95.2 versus 85.2) (p < 0.0001), and QuickDASH scores (10.9 versus 21.6) (p < 0.007) compared to those with any abnormal vascular examination. Patients with palpable pulses, regardless of symmetry, demonstrated significantly higher PODCI pain and comfort scores (94.6 versus 84.7) (p < 0.003) than NP pulses. CONCLUSIONS In children with operative SCHFX, an abnormal vascular examination at presentation is predictive of poorer outcomes in pain and upper extremity function. A palpable pulse, versus NP, is predictive of better pain and comfort at final follow-up. LEVEL OF EVIDENCE II.

Abstract
The epiphyseal tubercle, a posterosuperior projection of the epiphysis into the metaphysis, serves as the axis of rotation in slipped capital femoral epiphysis (SCFE) and a source of physeal stability. We hypothesized that in a biomechanical model of single screw fixation of stable SCFE, a screw passing through the epiphyseal tubercle (the axis of rotation) would confer less rotational stability than a centrally placed screw. Three femurs were selected from a sample population of 8- to 15-year-old healthy hips to represent three stages of maturation: a "young" femur with a prominent epiphyseal tubercle and decreased epiphyseal cupping around the metaphysis, a "median" femur with a subsiding tubercle, and a "mature" femur with a subsided epiphyseal tubercle and increased peripheral epiphyseal cupping. Specimens were three-dimensional printed with one of two screw trajectories: passing centrally in the epiphysis or directly through the epiphyseal tubercle. Resistance to rotational displacement was measured through stiffness and maximum torque over 30° degrees of displacement. In the "young" model, epiphyseal tubercle screw position conferred less rotational stiffness and required less maximum torque during rotational displacement when compared to a centrally placed screw (P < .001). In the "median" and "mature" models where the tubercle has subsided and is replaced by peripheral epiphyseal cupping, screw position through the tubercle was associated with equal or greater rotational stiffness and maximum torque during displacement as a centrally placed screw.

Abstract
BACKGROUND Although drill use is fundamental to orthopaedic surgery, the risk of plunging past the far cortex and potentially damaging the surrounding soft tissues remains unavoidable with conventional drilling methods. A dual motor drill may decrease that risk by providing controlled drill-bit advancement and real-time monitoring of depth and energy expenditure. We hypothesized that using the dual motor drill would decrease plunge depth regardless of the user's level of experience. METHODS Sixty-six subjects of varying operative experience (20 attending orthopaedic surgeons, 20 orthopaedic surgery residents, and 26 senior medical students) drilled 3 holes with a conventional drill and 3 holes with a dual motor drill in a bicortical Sawbones block set in ballistic gel. The depth of drill penetration into the ballistic gel was measured for each hole using a digital caliper. RESULTS Overall, subjects plunged less with the dual motor drill (0.9 mm) than with the conventional drill (4.2 mm) (p < 0.001). This finding was consistent within each group: attending surgeons (0.9 compared with 3.2 mm; p = 0.02), residents (1.0 compared with 3.0 mm; p < 0.001), and students (0.7 compared with 6.0 mm; p < 0.001). Plunge depths were also stratified into 3 categories: 0 to <2 mm, 2 to 5 mm, and >5 mm. Using the dual motor drill, subjects were more likely to plunge <2 mm (97% plunged, on average, 0 to <2 mm and 3% plunged, on average, 2 to 5 mm), whereas subjects were more likely to plunge deeper with the conventional drill (27% plunged, on average, 0 to <2 mm, 45% plunged, on average, 2 to 5 mm, and 27% plunged, on average, >5 mm). Notably, no subject plunged ≥2 mm on the third attempt with the dual motor drill. Attending surgeons (p = 0.02) and residents (p = 0.01) plunged less than students with the conventional drill. There was no significant difference between attending surgeons and residents with the conventional drill (p = 0.96). There was no significant difference in plunge depth between groups using the dual motor drill. CONCLUSIONS The dual motor drill significantly decreased plunge depth for both surgically experienced and inexperienced subjects. Although inexperienced subjects performed worse with the conventional drill than those with experience, there was no difference in their performance with the dual motor drill. CLINICAL RELEVANCE Use of a controlled advancement drill may decrease the chance of plunge-related neurovascular injury during in vivo drilling.

Abstract
BACKGROUND Neurovascular injury in pediatric supracondylar fractures (SCHFx) has been associated with fracture classification but not with soft tissue injury. The purpose of this study is to correlate clinical soft tissue damage to neurovascular injuries in SCHFx. METHODS This is an institutional review board approved prospective study from January 2010 through December 2013 of 748 operatively treated pediatric SCHFx. Prospective data were gathered both preoperatively and intraoperatively regarding detailed neurovascular examination as well as soft tissue status, with qualitative descriptives for swelling (mild/moderate/severe), ecchymosis, abrasions, skin tenting, and skin puckering. RESULTS A total of 7.8% of patients (41/526) had a nonpalpable radial pulse preoperatively. Compared with those with a palpable pulse, a nonpalpable pulse was associated with severe elbow swelling (P<0.0001), tenting (P=0.0085), puckering (P=0.0011), ecchymoses (P<0.0001), and open fracture (P=0.044). Ten patients had a loss of a palpable pulse from initial orthopaedic consult to time of surgery, and when compared with the patients who did not have a loss of pulse, this was associated with swelling severity (P=0.0001) and ecchymosis (P=0.053). A total of 14% of patients (71/526) had a neurological injury preoperatively, and this was associated with severe elbow swelling (P<0.0001), tenting (P=0.0008), puckering (P=0.0077), and ecchymoses (P<0.0001) when compared with patients who did not have a neurological injury. In total, 17 patients had a decline in their neurological examination from the time of initial orthopaedic consult to the time of surgery, and this was associated with severe elbow swelling (P=0.0054) and ecchymoses (P=0.011). After multivariate logistic regression analysis, severe swelling and ecchymoses were significantly associated with a nonpalpable pulse as well as neurological injury (P<0.05). No patient had compartment syndrome. CONCLUSIONS Soft tissue injury, as measured by swelling, ecchymosis, puckering, and tenting, had a clinically significant association with neurovascular compromise in pediatric SCHFx, and assessment of soft tissue injury is as important as the radiographic appearance when examining these patients. The physical examination signs of soft tissue injury may play a factor in determining urgency of surgical treatment in these fractures. LEVEL OF EVIDENCE Level II-therapeutic.

Abstract
The management of pediatric fractures has evolved over the past several decades, and many injuries that were previously being managed nonoperatively are now being treated surgically. The American Academy of Orthopaedic Surgeons has developed clinical guidelines to help guide decision making and streamline patient care for certain injuries, but many topics remain controversial. This article analyzes the evidence regarding management of 5 of the most common and controversial injuries in pediatric orthopedics today.

Abstract
BACKGROUND Toe walking (TW) in children is often idiopathic in origin. Our purpose was to determine the incidence of a neurological etiology for TW in patients seen in the neurology clinic after referral from pediatric orthopaedic surgeons. METHODS We performed an Institutional Review Board approved retrospective review of 174 patients referred to the neurology clinic from orthopaedic surgeons at an academic pediatric tertiary care center between January 2010 and September 2015. Medical records were reviewed and data recorded including pertinent family history, birth history, age of initial ambulation, physical examination findings, and workup results including neuroimaging, neurophysiological studies, and findings of genetic testing and tissue biopsy. RESULTS Sixty-two percent (108/174) of patients were found to have a neurological etiology for TW. Final pathologic diagnoses were: 37% (40/108) previously undiagnosed cerebral palsy (CP), 16.7% (18/108) peripheral neuropathy, 15.7% (17/108) autism spectrum disorder, 13.9% (15/108) hereditary spastic paraparesis, 8.3% (9/108) attention deficit hyperactivity disorder, 5.6% (6/108) syndromic diagnosis, and 2.8% (3/108) spinal cord abnormality. Ankle equinus contractures were noted in idiopathic and neurological patients and did not indicate a pathologic origin. Seventy-one percent of unilateral toe walkers and 32% of bilateral but asymmetric toe walkers were diagnosed with CP (P<0.001). Twenty-six percent of 145 brain magnetic resonance imaging studies diagnosed CP. Of the 125 (72%) with spinal imaging, 3 had spinal pathology to account for TW. Fourteen percent of 87 subjects with an electromyography/nerve conduction study had abnormal results indicating a peripheral polyneuropathy. CONCLUSIONS An underlying pathologic diagnosis was found in 62% of patients referred to neurology for TW. A concerning birth history, delayed initial ambulation, unilateral TW, upper or lower motor neuron signs on examination, or behavioral features may suggest a pathologic diagnosis. Ankle contracture is not predictive of an abnormal diagnosis and can be found in idiopathic patients. CP, peripheral neuropathy, autism spectrum disorder, and hereditary spastic paraparesis are the most common pathologic diagnoses identified in our population.

Abstract
BACKGROUND Few studies have prospectively assessed functional outcomes after the surgical management of supracondylar humerus fractures (SCHFXs) and the relationship between fracture pattern and ultimate patient outcome has never been prospectively evaluated. The purpose of this study was to prospectively evaluate fracture classification and functional outcome in children with extension SCHFXs using validated outcome measures. METHODS An Institutional Review Board-approved prospective enrollment of consecutive patients with operative SCHFX was performed over a 3-year period. Fractures were classified by the treating surgeon using the modified Gartland classification. Functional outcome was assessed at final follow-up using the Pediatric Outcomes Data Collection Instruments (PODCI) and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) outcome measure. Patients with flexion-type fractures, multidirectionally unstable fractures and those with <10 weeks follow-up were excluded from analysis. Statistical analysis was used to determine the relationship between fracture classification/pattern and functional outcome. RESULTS Seven hundred fifty-two patients were enrolled during the study period. One hundred thirty-two patients with extension-type injuries (average age 6.7 y) completed functional outcome measures at an average follow-up of 12.4 weeks. Forty-five (34%) were type II fractures and 87 (66%) were type III fractures. Forty-five (34%) of the fractures were posteromedially displaced, 43 (33%) were posterolaterally displaced, and 44 (33%) were posteriorly displaced without coronal plane deformity. The average PODCI global functioning scale score and QuickDASH scores for the entire cohort were 93.6 and 11.4, respectively, indicating excellent function. No differences in outcome scores were noted between patients with type II and III fractures. No difference in outcome was identified based upon direction of fracture displacement. CONCLUSIONS This is the first study to prospectively analyze fracture classification and functional outcome using validated outcome measures following the operative treatment of pediatric extension-type SCHFX. Children generally have excellent functional outcomes following the operative treatment of SCHFX. Garland classification and direction of displacement do not influence functional outcomes.

Abstract
BACKGROUND CONTEXT Lateral distraction injuries represent a very rare pattern of injury with only five cases reported in the literature. Such injuries are a result of high-energy trauma and have a high association with severe concomitant injuries. All previous reports of this injury are in skeletally mature individuals, and this has not been previously described in young children. PURPOSE To report a case of a lateral distraction injury in a young child secondary to improper seat belt use. STUDY DESIGN Case report and review of the literature. PATIENT SAMPLE Case report of an 8-year-old girl involved in a highway speed head-on collision. METHODS We report here on an 8-year-old girl who was lying supine in the backseat of a motor vehicle while wearing a lap belt when the vehicle was involved in a high-speed motor vehicle crash. She presented with focal back pain, abdominal pain, and a seat belt sign. Imaging demonstrated focal coronal plane deformity with unilateral ligamentous disruption. The patient was diagnosed with a ligamentous lateral distraction injury of the lumbar spine. This injury was treated with open reduction and posterior spinal fusion with pedicle screw fixation. RESULTS The patient tolerated the procedure well and had an uneventful postoperative course. CONCLUSIONS In this case, we describe a lateral distraction injury in a young child secondary to improper seat belt use. This represents the first description of such an injury in this age group, and this case highlights the spectrum of injury caused by improper seat belt use in the pediatric population.

Abstract
Flexion-distraction injuries represent an uncommon pattern of injury in the pediatric population. Although this is a well-studied topic in adults, the literature on such injuries in children and adolescents is relatively sparse, with only low levels of evidence available to guide treatment. These injuries carry a high rate of concomitant injuries and a high morbidity and mortality in this population. Proper understanding of these complex injuries is important to ensure proper management and avoid complications.

Abstract
Abstract
BACKGROUND:
Lumbar interbody fusion has been extensively studied in the civilian population; however, data regarding its efficacy in the military are lacking.
OBJECTIVE:
To identify the rate of return to unrestricted active military duty after single-level lumbar interbody fusion surgery.
METHODS:
The surgical database at a single tertiary care military treatment facility was queried for active-duty patients who underwent a single-level lumbar interbody fusion over a 5-year period. A retrospective chart review was performed with backward stepwise logistic regression analysis, and Fisher exact and Wilcoxon rank sum tests were used for statistical analysis.
RESULTS:
A total of 102 patients met the inclusion criteria. Mean age at surgery was 34.0 years (range, 19–51 years). Most surgeries (59%) were performed for discogenic pain secondary to degenerative disc disease; the remaining patients underwent surgery for spondylolisthesis (39%) or spinal stenosis (2%). Thirty-nine patients (38%) were treated via an anterior approach (anterior lumbar interbody fusion), whereas 63 patients (62%) underwent fusion via a posterior approach (transforaminal or posterior lumbar interbody fusion). Fifty-six patients (55%) were able to return to unrestricted full active duty, and the remaining 46 patients (45%) were separated from the military. The return to active duty rate was significantly higher in older patients and those ranking E7 (Chief Petty Officer) and above (84.8%).
CONCLUSION:
Fifty-five percent of the service members who underwent a single-level lumbar interbody fusion returned to unrestricted full duty. Older age and higher rank were statistically significant positive predictors of a successful return to active duty.

Abstract
BACKGROUND The constrained working area in minimally invasive exposures of the spine may limit the capacity to effectively close the lumbar fascia, especially in patients with elevated body mass indexes. The working channel in these cases may have a diameter as narrow as 14 mm and a length up to 9 cm. Under these circumstances, the use of a conventional needle driver and a curved needle becomes suboptimal for closures of the fascia. OBJECTIVE To demonstrate the utility of an arthroscopic suture passer for closure of the lumbar fascia in such approaches. METHODS A flexible suture passer, typically used in arthroscopic rotator cuff repair surgery, was used through a minimally invasive portal for fascial closure after minimally invasive lumbar spine procedures. RESULTS The use of an arthroscopic suture passer precludes the need for rotation of a curved needle in a constrained working area. Deploying a nitinol needle through an arc delivers the suture through the fascia, thereby facilitating closure. Satisfactory lumbar fascia closures were achieved in 18 patients with elevated body mass indexes. CONCLUSION Application of existing technology in other surgical specialties may address the shortcomings of current techniques in minimally invasive approaches to the spine. The use of a flexible arthroscopic suture passer is one example in which current technology in one discipline may be applied to minimally invasive approaches. Increasing the awareness of techniques and instruments in other surgical disciplines may expand the armamentarium of the minimally invasive spine surgeon.

Abstract
Turret exostosis is a benign osteocartilagenous lesion believed to arise from reactive perisoteum following relatively mild trauma. This article presents an unusual case of a turret exostosis of the talar neck in a 12-year-old child. A healthy adolescent presented with a 5-month history of a firm, painless mass about the anteromedial aspect of the right ankle 1 month after suffering a mild twisting injury to the ankle. Radiographs demonstrated a benign-appearing bony mass within the soft tissues anterior to the right ankle overlying the talar neck. An excisional biopsy of the mass was performed and pathology was consistent with turret exostosis, demonstrating a central area of mature trabecular bone maturing via enchondral ossification with a thin hypocellular peripheral rim of cartilage. The absence of a periosteal layer, abundant "blue bone," bizarre metaplastic cartilage, or marked cytologic atypia confirmed the diagnosis. The patient remains pain free with full ankle motion. Reactive periosteal lesions are well-described entities, tending to occur with the greatest frequency in the small bones of the hand. Few cases of bizarre parosteal osteochondromatous proliferation in the metatarsals and phalanges of the toes have been reported. The current case represents the first account of a turret exostosis of the hindfoot, and the youngest patient with a histologically confirmed diagnosis. It further illustrates the manner in which this case exists along a continuous spectrum of reactive periosteal lesions. The clinical, radiographic, and histologic characteristics of reactive periosteal lesions are reviewed.

Abstract
UNLABELLED Acetabular retroversion (AR) alters load distribution across the hip and is more prevalent in pathologic conditions involving the hip. We hypothesized the abnormal orientation and mechanical changes may predispose certain individuals to stress injuries of the femoral neck. We retrospectively reviewed the anteroposterior (AP) pelvic radiographs of 54 patients (108 hips) treated for a femoral neck stress fracture (FNSF) and compared these radiographs with those for a control group of patients with normal pelvic radiographs. We determined presence of a crossover sign (COS), femoral neck abnormalities, and neck shaft angle. The prevalence of a positive COS was greater in patients with stress fractures than in the control subjects (31 of 54 [57%] versus 17 of 54 [31%], respectively) and higher than for control subjects reported in the literature. Thirteen patients had radiographic changes of the femoral neck consistent with femoroacetabular impingement (FAI). These radiographic abnormalities were seen more commonly in retroverted hips. A greater incidence of AR was noted in patients with FNSF. Potential implications include more aggressive screening of military recruits with AR and the new onset of hip pain. Finally, we present an algorithm we use to diagnose and treat these relatively rare FNSFs. LEVEL OF EVIDENCE Level II, prognostic study.

Abstract
BACKGROUND Skimboarding is a beachside water sport that is enjoying increasing popularity among both dedicated enthusiasts and casual beachgoers. Although many consider this sport to be similar to its "sister" sport, surfing, the technique, the environment in which it is performed, and the skills required differ dramatically from that of surfing. Moreover, the pattern of injuries seen in skimboarders differs substantially from those sustained while surfing. HYPOTHESIS A better understanding of the injuries encountered in this sport will allow improved participant education and facilitate the implementation of preventative measures. STUDY DESIGN Descriptive epidemiology study. METHODS A case series was generated by performing a single retrospective chart review of skimboarding injuries referred for orthopaedic evaluation over a 2-year period at 2 medical treatment facilities, one on the East Coast and one on the West Coast of the United States; demographic data, injury type, and treatments rendered were documented. RESULTS Sixty-one patients were identified and analyzed. Average patient age was 19.1 years. Fractures represented 93.4% of all acute injuries. The most common sites of injury were the ankle (41%) and wrist (36%). Rotation about a planted lower extremity was the most common mechanism of injury (30/61, 49%), followed by falls onto an outstretched hand (26/61, 43%). CONCLUSION Fractures of the ankle and wrist comprise a high proportion of skimboarding injuries. Knowledge of potential hazards associated with this sport should be made available to participants. To decrease the risk of orthopaedic injury, the use of protective equipment or instruction in proper techniques of the activity may be warranted.

Abstract
Breast, prostate, renal, thyroid, and lung carcinomas commonly metastasize to bone. Managing skeletal metastatic disease can be complex. Pain is the most common presenting symptom and requires thorough radiographic and laboratory evaluation. If plain-film radiography is not sufficient for diagnosis, a bone scan may detect occult lesions. Patients with lytic skeletal metastases may be at risk for impending fracture. Destructive lesions in the proximal femur and hip area are particularly worrisome. High-risk patients require immediate referral to an orthopedic surgeon. Patients who are not at risk for impending fracture can be treated with a combination of radiotherapy and adjuvant drug therapy. Bisphosphonates diminish pain and prolong the time to significant skeletal complications.

Abstract
BACKGROUND Patients with congenital osseous anomalies of the spine are known to have a high prevalence of abnormalities in the renal system and of the spinal cord. Today, the screening tools of choice to detect these abnormalities include ultrasonography of the kidneys and collecting system and magnetic resonance imaging of the spine. A single screening tool that can identify both renal and intraspinal anomalies would be ideal. METHODS Imaging studies of all patients with a congenital osseous anomaly of the spine seen at our institution during a ten-year period were retrospectively reviewed. Only patients who had had both a sonogram of the renal system and a magnetic resonance imaging study of the entire spine were included in the investigation. All studies were reviewed blindly by a pediatric radiologist for this study. RESULTS One hundred and fifty-three patients met the criteria for inclusion in the study. Forty-one patients (27%) had a total of forty-seven renal abnormalities noted on both the sonogram and the magnetic resonance imaging scan. In no instance was a renal anomaly seen on one study and not on the other. CONCLUSIONS When properly performed, screening magnetic resonance imaging scans of the spine can show renal abnormalities, thus obviating the need for a separate screening renal ultrasound study.

Abstract
To assess the role of stainless steel flexible intramedullary fixation in unstable pediatric femur fractures, we compared a group of 41 stable (transverse or oblique) fractures with a group of 40 unstable (spiral and/or comminuted) fractures treated with stainless steel (Ender) nails placed through a single lateral insertion. The fractures were followed up until clinical and radiographic union was evident with an average follow-up period of 13 months. All fractures were healed at an average of 1.4 months. No infections or refractures occurred. Although minor radiographic angular deformities and shortening were present in both groups, no patient had a clinically detectable angular deformity. Two patients with stable fracture patterns had 10 to 20 degrees of asymmetry in foot progression angles, and 1 patient with an unstable fracture pattern (Winquist grade IV comminution) had a 3-cm limb length difference at final follow-up. Stainless steel flexible intramedullary fixation is effective for unstable pediatric femur fractures if cortical abutment is present.
