الوصف: Author(s): Goldin, Amanda N; Muzykewicz, David A; Mubarak, Scott J | Abstract: BackgroundNonossifying fibroma (NOF) is the most common benign osseous lesion in children; however, our understanding of which lesions progress to a fracture remains unclear. In this study, we seek to formulate a classification system for NOFs to assess for fracture risk and determine what this classification system tells us regarding fracture risk of the distal tibia and distal femur NOFs.MethodsCharts were retrospectively reviewed for patients with NOFs. A 4-point criteria was created and used to calculate fracture risk for distal tibia and distal femur NOFs. The analysis included incidence, specificity, and sensitivity.ResultsOne point was given for each of the following findings on computed tomography (CT) scan: (1) g50% width on coronal view; (2) g50% width on sagittal view; (3) any cortical breach; (4) lack of a neocortex. In total, 34 patients with NOFs of the distal tibia had CT scans, of which 14 fractured. Zero with a 0- or 1-point score fractured, 2 with a 2-point score fractured (20%), 4 with a 3-point score fractured (44%), and 8 with a 4-point score fractured (100%). Sensitivities of 1-, 2-, 3-, and 4-point scores were 100%, 100%, 85.7%, and 57.1%, respectively, and specificities were 71.4%, 71.4%, 80%, and 100%, respectively. A total of 41 patients with NOFs of the distal femur had CT scans, of which 5 fractured. Zero with a 0-point score fractured, 1 with a 1-point score fractured (4%), 0 with a 2-point score fractured, 1 with a 3-point score fractured (20%), and 3 with a 4-point score fractured (100%). Sensitivities of 1-, 2-, 3-, and 4-point scores were 100%, 80%, 80%, and 60%, respectively; and specificities were 60%, 87.8%, 90%, and 100%, respectively.ConclusionsOur 4-point CT criteria is easy to apply and identifies patients at high risk of fracture, helping surgeons make decisions regarding treatment.Level of evidenceLevel IV-prognostic study.

الوصف: Purpose There is significant variability in brace treatment indications for infantile acetabular dysplasia in the absence of hip dislocation or subluxation. This study’s purpose was to evaluate characteristics of treated and untreated patients in our practice. Methods A retrospective chart review was performed of patients aged 0-12 months who were referred to orthopedics with concern for DDH. Demographic and clinical information, as well as provider and radiographic information were recorded for analysis. Five surgeons were independently asked to review de-identified radiographs and note which subjects warranted treatment. A consensus diagnosis of “dysplasia”, “no dysplasia”, or a lack of consensus were considered as independent variables. Univariate and Classification and Regression Tree (CART) analysis was performed to determine predictors of treatment. Results Mean acetabular inclination (30.6o vs. 28.2o; p=0.006) and the incidence of abnormal abduction (p=0.002) were higher for the group that was treated for dysplasia. CART analysis showed that patients with a consensus diagnosis of radiographic dysplasia were more likely to receive treatment than those without consensus, or a consensus of no dysplasia (p

الوصف: Purpose Asymmetric skin folds (ASFs) have been linked to developmental dysplasia of the hip (DDH) in select studies, leading to their inclusion in paediatric practice guidelines regarding orthopaedic referral for hip evaluation. The purpose of this study was to investigate the utility of isolated ASFs as a screening tool for DDH in a series of patient referrals evaluated at a single institution. Methods We performed a retrospective review of consecutive patients between 0 and 12 months of age referred to orthopaedic clinics for isolated ASFs. We recorded radiographic findings (acetabular inclination or alpha angle), diagnosis rendered and treatment administered. Results A total of 66 patients were included (mean age 6.4 months; 2.47 to 10.76). All patients received pelvic radiographs or ultrasound. In all, 36 patients (55%) were considered normal by their treating physician and 25 (38%) were considered dysplastic and underwent brace treatment. One hip with an isolated ASF was found to have a dislocated hip on radiograph prior to their initial orthopaedic visit. None of the patients in this study have required surgery to date. Conclusion Using ASFs as a reason for referral led to increased diagnosis of mild dysplasia resulting in orthotic treatment. Thus, in our particular clinical environment, isolated ASFs can be an indicator of mild dysplasia and warrant further workup or referral. Because treatment philosophies regarding recognition and treatment of mild dysplasia vary amongst centres, the value of screening with ASFs likewise depends on the treating orthopaedic surgeon's threshold for treatment of mild dysplasia.

الوصف: BACKGROUND: The ligamentum teres (LT) is believed to have a number of functions, including a role in hip stability, nociception, proprioception, vascular supply to the femoral head, and synovial fluid circulation. The LT is often excised in the process of performing a medial open reduction (MOR) of the hip. We sought to conduct a retrospective review of hips undergoing a MOR for dislocated infantile developmental dysplasia of the hip (DDH) to compare clinical and radiographic outcomes for patients with and without LT reconstruction. METHODS: We performed a retrospective review of 38 hips treated with MOR with or without LT reconstruction with minimum two-year follow-up. Radiographic outcomes were determined using the Severin score. Information regarding avascular necrosis (AVN), concomitant surgical procedures, repeat dislocation, subsequent surgery, limp, pain, and range of motion symmetry was recorded. RESULTS: Eighteen hips that underwent MOR with LT reconstruction were compared to 20 hips that underwent MOR without LT reconstruction. Mean follow up for this cohort was 70.1 months (median: 61.8; Range: 24.2 to 182.2 months). The group with LT reconstruction had an 11% rate of AVN, the group without LT reconstruction had a 15% rate of AVN (p=1.0) No hips in either group re-dislocated or had pain at final follow up. Two hips (5%) had a limp at most recent follow up, all were in the group that did not receive a LT reconstruction (p=0.488). Three hips (17%) in the LT reconstruction group and one hip (5%) in the other group had asymmetrical hip range of motion at final follow up (p=0.328). CONCLUSION: This study offers preliminary data to suggest that ligamentum teres reconstruction is a safe procedure that can minimize the risk for subluxation or re-dislocation that can occur within the post reduction hip spica cast. Although in this study, the patients who did not have LT reconstruction had a similar re-dislocation rate, we believe that ligamentum teres preservation is a useful adjunct to medial open reduction, especially in centers that may only treat occasional cases or have less experience in applying an excellent hip spica cast.

المؤلفون: Raghav Badrinath, Scott J. Mubarak, Vidyadhar V. Upasani, James D. Bomar, Dennis R. Wenger

المصدر: Journal of Children's Orthopaedics

الوصف: Purpose Patients with developmental dysplasia of the hip (DDH) may require a pelvic osteotomy to treat acetabular dysplasia. The Pemberton osteotomy and modified San Diego acetabuloplasty are two options available when surgically treating DDH. The purpose of this study was to compare outcomes following the Pemberton and modified San Diego when treating patients with acetabular dysplasia in typical DDH. Methods We included 45 hips in the modified San Diego group and 38 hips in the Pemberton group. Hips with less than two years follow-up and patients with a neuromuscular diagnosis were excluded. Clinical outcomes were rated using the modified McKay criteria with radiographic outcomes graded using the Severin score. Avascular necrosis (AVN) was assessed using the Kalamchi and MacEwen criteria. Results Mean follow-up was 4.9 years (2.1 to 11.2). Both procedures produced similar decreases in the acetabular index (modified San Diego: 17.0° versus Pemberton: 15.2°; p = 0.846). Most hips had good/excellent results using the modified McKay criteria (modified San Diego: 78%, Pemberton: 94%; p = 0.055). Most hips were rated as good/excellent on the Severin scale (modified San Diego: 100%, Pemberton: 97%, p = 0.485). The proportion of hips with AVN grade 2 or higher were similar between groups (modified San Diego: 0%, Pemberton: 3%; p = 0.458). Conclusion The modified San Diego acetabuloplasty is a safe and effective alternative to treat acetabular dysplasia in patients with typical DDH. By maintaining an intact medial cortex, acetabular reshaping can be customized to address each patient's specific acetabular deficiency Level of evidence Level III retrospective comparison

الوصف: BACKGROUND The role of femoral aspiration (FA) in the treatment of septic arthritis of the hip is controversial. The purpose of this study was to determine if FA conducted concomitantly with irrigation and debridement (I&D) of the septic hip aids in microorganism and osteomyelitis identification and alters the treatment plan, or if the risks of the procedure outweigh its potential benefit. We also compare preoperative magnetic resonance imaging (MRI) with FA for diagnosis of osteomyelitis cooccurring with septic arthritis. METHODS Retrospective review was performed of all patients treated at a single institution between January 2003 and June 2014 for suspected septic hip arthritis. Eighty-three patients were identified with suspected or confirmed septic arthritis and 28 patients (33%) had cooccurring osteomyelitis. Demographic and clinical data were recorded for each patient. The sensitivity and specificity of FA and MRI for diagnosing osteomyelitis were determined. RESULTS Among the 83 patients with confirmed or suspected septic arthritis, 31 patients (37%) had a FA performed at the time of the hip I&D, resulting in positive cultures in 17 patients. All of these patients had other positive cultures (blood and/or joint fluid) that grew the same organism. 54 patients (65%) had a preoperative MRI. The MRI was falsely negative in 10 patients, 6 of whom had a positive FA resulting in appropriate management of osteomyelitis. Missed or delayed diagnosis of osteomyelitis resulted in significant morbidity in 3 patients (avascular necrosis and femoral neck fracture, extensive lower extremity osteomyelitis, and subtrochanteric fracture with malunion). No complications associated with FA were identified. FA and MRI were found to have sensitivity/specificity for osteomyelitis of 100%/100% and 38%/95%, respectively. CONCLUSIONS Although FA did not improve microorganism identification, it did aid in the diagnosis of cooccurring osteomyelitis when treating children with septic arthritis, especially in patients with false negative MRI findings for osteomyelitis. We recommend FA at the time of septic hip I&D as its benefits appear to far outweigh its risks. LEVEL OF EVIDENCE Level III-diagnostic study.

Ankle Ganglion Associated with Tarsal Coalition: A Case Report with a 5-Year Follow-up

المؤلفون: Vanna Rocchi, Scott J. Mubarak

المصدر: JBJS case connector. 10(3)

الوصف: Case Talocalcaneal coalition (TCC) is a common type of coalition, often neglected. This case is of a 10-year-old girl with a painful ankle mass, diagnosed with TCC and a ganglion cyst. Examination revealed stiff subtalar motion, a submalleolar prominence, and well-circumscribed, tender mass at the posteromedial ankle. Treatment options include short period of casting/observation, excision vs. aspiration of the cyst, resection of the TC coalition, or a combination of the above. She underwent TCC resection with cyst aspiration. Conclusion At the 5-year follow-up, the patient's examination and imaging revealed normal motion without cyst recurrence, indicating resolution of the cyst with coalition resection.

الوصف: Case We describe the first reported case of scurvy developing secondary to behavioral traits of Jacobsen syndrome. The diagnosis of scurvy was significantly delayed because bleeding symptoms were initially attributed to baseline thrombocytopenia and platelet dysfunction associated with Jacobsen syndrome and patient's medication. Following vitamin C supplementation, signs and symptoms of the patient's disease quickly resolved. Conclusions We aim to reinforce the need to consider nutritional deficiencies in patients with complex medical histories and behavioral issues, especially when presenting with new complaints.

Unsuspected tarsal coalitions in equinus and varus foot deformities

المؤلفون: Scott J. Mubarak, Noelle L Van Rysselberghe, Christopher D. Souder

المصدر: Journal of pediatric orthopedics. Part B. 29(4)

الوصف: Tarsal coalitions have been reported in the setting of equinovarus foot deformities, but only as rare isolated findings. Failure to recognize this diagnosis may inhibit successful equinovarus correction. Here, we review a series of tarsal coalitions seen in congenital and neuropathic equinovarus deformity at two institutions, to report the breakdown of types of coalitions encountered, and to suggest methodology to facilitate earlier diagnosis. The records of all patients treated by two of the authors for bilateral equinovarus deformities and found to have either a unilateral or bilateral tarsal coalition between 2006 and 2016 were reviewed. Nine feet with tarsal coalition (calcaneonavicular n = 7 and talocalcaneal n = 2) were reviewed. Five of these cases occurred in patients with idiopathic equinovarus and four cases in patients with equinovarus related to a neurologic disease. All patients were definitively diagnosed by computed tomography scans with 3D reconstruction. In 56% of cases, the patient had previously undergone at least one open procedure before the coalition was recognized. The mean age at diagnosis of the coalition was 11.4 years. Our experience suggests that tarsal coalitions, particularly calcaneonavicular coalitions, may occur more frequently in equinovarus deformities than previously reported. Upon recognition and removal of these coalitions, we were able to achieve improved correction of the equinovarus deformities and improved range of motion. We recommend that surgeons maintain an awareness of this potential concomitant problem in all equinovarus foot deformities and consider advanced imaging in cases which fail to respond to traditional treatment.
