Physeal closure after slipped capital femoral epiphysis fixation can be difficult to assess on two-dimensional conventional radiographs. Radiostereometric analysis offers improved motion detection over conventional radiography, whereas the EOS biplanar imager provides a means for low radiation weight-bearing images. This phantom study assessed the reliability of measuring motion using radiostereometric analysis in the EOS using a slipped capital femoral epiphysis model. The accuracy and precision were better than 0...

All patients with hypertonic cerebral palsy undergoing Bernese periacetabular osteotomy (PAO) between 2005 and 2014 were reviewed. Clinical and radiographic parameters, including the cerebral palsy hip classification and anterior and posterior wall indices were collected to assess acetabular reorientation. Twenty (83%) of 24 procedures involved the correction of posterolateral acetabular insufficiency and were 'anteverting PAOs'. All 20 experienced improvements in radiographic indices. Eleven (58%) of 19 PAOs in ambulatory patients were performed in the setting of other multilevel orthopedic surgery...

The aim of this study was to establish the torsional and toe-walking profiles of children with autism spectrum disorder (ASD), and to analyze the correlations between torsion, toe-walking, autism severity score, and age. In total, 79 consecutive children with autism were examined to determine their hip rotations, thigh-foot angle, degree of toe-walking, and autism severity. Femoral and tibial torsion values, of the preschool patients, were compared statistically with age-matched controls. The hip rotation profile of the patients was similar to the normal group...

The relationship between curve correction and spinal length gain in adolescent idiopathic scoliosis was examined. A total of 102 patients who underwent posterior spinal correction and fusion alone or in combination with anterior spinal correction and fusion (ASF) were studied. The Cobb angle correction, increase in the main thoracic length, T1-L5 spinal length gain, and T1-L5 spinal length gain/Cobb angle correction were reported. The length gain/Cobb angle correction value was not significantly associated with sex, fusion approach, and the number of fused levels...

Treatment of unicameral bone cysts (UBC) in the humerus with drainage screws is scarcely reported in the literature. The aim of this retrospective study was to compare drainage screws and alternative treatment methods with respect to the number of required surgical procedures to achieve sufficient UBC healing, postoperative fractures/recurrences/complications, and radiological outcome. Medical archives of two tertiary orthopedic referral centers were screened for all patients who were treated surgically for humeral UBC in the period 1991-2015 with a histologically/cytologically confirmed diagnosis...

A total of 28 068 infants were studied to investigate whether universal ultrasound screening for developmental dysplasia of the hip results in fewer delayed presentations than selective screening, and whether the screening protocol affects subsequent treatment. The rate of delayed presentation was not lower with selective screening compared with universal screening but all cases of delayed presentation in this cohort were administrative errors. There were no sonographic errors (false-negatives). The treatment rate was significantly higher with universal screening but infants were treated earlier and were significantly less likely to require any surgical intervention...

In our study, we aimed to demonstrate whether a complex iatrogenic clubfoot really exists; identify the causative mechanisms; and determine the outcome if properly treated. We observed 54 clubfeet previously treated unsuccessfully by manipulation and casting elsewhere. All the feet had been classified at diagnosis as typical clubfeet. In 26 cases, the cast had slipped down, entrapping the foot in a plantar-flexed position. Nine clubfeet out of those 26 cases presented the clinical features of a complex iatrogenic deformity...

This research focuses on femoral head wedge resection for the treatment of avascular necrosis (AVN) of the femoral head. A 9-year-old girl presented to the emergency room complaining of right hip pain that occurred after a pedestrian car accident. After 8 months of internal fixation using cannulated screws for Delbet-type 2 fracture of the femoral neck, AVN of the femoral head developed in the patient. Even though valgus-derotation-extension intertrochanteric osteotomy was performed for the treatment of AVN, it progressed further and femoral head wedge resection was performed to recover the femoral head sphericity...

Because of the known tendency for early redislocation following open reduction, we developed surgical methods for shortening the ligamentum teres to improve immediate postoperative stability when performing medial approach open reduction (MAOR) for the management of developmental dysplasia of the hip. Between 2004 and 2014, 32 patients with dysplasia of the hip were managed by MAOR with partial excision and plication of ligamentum teres. The patients were followed up for an average of 6.9 years. At the final follow-up, clinical outcomes achieved were categorized as excellent and good in 39 (39/40; 97...

Generalized joint hypermobility (GJH) is a risk factor for developing adolescent idiopathic scoliosis (AIS); however, it is not known whether joint hypermobility influences the risk of progression to surgery. Beighton joint hypermobility scores were assessed in 570 female AIS patients. Multivariate analysis was carried out to determine whether Beighton hypermobility scores were predictors of surgical intervention. In this female AIS cohort, 24.7% (141/570) had GJH (Beighton score ≥4). Multivariate analysis showed that GJH did not influence the risk of surgery, although having no joint hypermobility (Beighton score=0) increased risk (odds ratio: 1...

Although there are many factors that are likely to influence the need for open reduction and percutaneous pinning (ORPF) in the treatment of pediatric supracondylar humerus fractures (SCHFs), the role of surgeon's experience (as represented by the total number of surgically treated SCHFs) on the need for ORPF has seldom been investigated. We reviewed the data on all completely displaced, pediatric SCHFs that were treated surgically by a single, fellowship-trained, pediatric orthopedic surgeon over the first 10 years of the surgeon's clinical practice...

There is an increased incidence of scoliosis in patients with congenital malformations of the upper extremity even in the absence of overt vertebral abnormalities. In this case series, we summarize the curve characteristics of four patients presenting to two spine surgery clinics with unilateral amelia or phocomelia and a progressive scoliotic curve with the apex on the side of deficiency. All patients required orthopedic intervention for their curves. Amelia and phocomelia are severe congenital malformations of the upper limb affecting trunk balance and, conceivably, causing scoliosis with the absence of counterbalancing weight on the affected side...

The surgical approach for open reduction and internal fixation of lateral condyle fractures in children is controversial. Some authors recommend the lateral approach to the elbow over the posterior approach because of theoretical concern for injury to the vascular supply of the distal humerus and potential avascular necrosis (AVN). The purpose of this retrospective case series study is to report the outcomes of open reduction and internal fixation of displaced lateral condyle fractures of the humerus by the posterior approach...

The main aim of this study was to retrospectively evaluate the clinical, functional, and radiographic outcome of displaced intercondylar fractures of the humerus in children and adolescents, and evaluate upper-extremity function with the short version of the Disabilities of the Arm, Shoulder and Hand outcome questionnaire (Quick DASH), the hypothesis being that intercondylar fractures have poorer functional outcome than do other upper-limb fractures. The mean age at the time of injury was 11.9±2.5 years (range: 7...

Does scoliosis severity increase scoliosis risk or severity in relatives? In a cohort of 1257 severe idiopathic scoliosis patients, the percentage with at least one affected relative was compared across the categories of patient sex, major curve severity (Cobb angle), and treatment method. In total, 138 (11%) of 1257 patients had at least one affected first-degree relative and 59 (5%) had at least one affected second-degree relative. As expected, males were more likely to have affected first-degree relatives than females (18 vs...

Distal humeral extension-type malunions may occur as a complication following improper reduction of supracondylar humerus fractures. We evaluated results after distal humeral flexion osteotomies for sagittal realignment of the humeral condyle in children. Medical records and radiographs of all patients younger than 18 years of age, who underwent this procedure because of a clinically relevant lack of elbow flexion, were evaluated. In a cohort of 18 children with a mean age of 8 years at the time of surgery and a mean follow-up duration of 1 year, elbow flexion increased significantly from a mean of 101° preoperatively to 126° at the final follow-up; established radiographic parameters (e...

To determine the prevalence of thoracic scoliosis in patients 10-20 years old using radiographs as a screening tool, we studied 783 patients who obtained chest radiographs for nonspinal reasons. We measured thoracic curvature in coronal and sagittal planes; we determined whether age, sex, and sagittal curvature predicted the coronal curvature. The prevalence of scoliosis was 9.3%: 7.0% had curvatures 10°-20°; 1.0% had curvatures 20°-30°; and 1.3% had curvatures of at least 30°. Females (13%) presented larger prevalence of scoliosis than males (4...

Although most pediatric proximal humeral fractures can be successfully treated conservatively with satisfactory results, many operative techniques have been described for the treatment of displaced proximal humeral fractures. The aim of this study is to evaluate the efficacy of percutaneous fixation using a modified palm tree technique for proximal humerus fractures in children. Between March 2011 and May 2013, the modified palm tree technique was used for the management of 30 children (20 boys and 10 girls) with displaced proximal humeral fractures...

Almost half of growing rod (GR) patients that undergo final fusion (FF) have an extension of instrumented levels. The purpose of this study was to review sagittal plane radiographic parameters of patients with distal extension of instrumented levels at FF to those whose levels remained the same. Radiographs were assessed preoperatively, after GR insertion/first lengthening, following GR treatment before FFs, and after FF. Measurements included sagittal balance, lumbar lordosis, thoracic kyphosis, and distal junction angle (DJA)...

This study explored the radiological, functional, and cosmetic results of treatment of supracondylar humeral fractures with open reduction and percutaneous pinning, comparing posterior triceps V-splitting (group I, n=22) and lateral (group II, n=25) approaches. The time to union, the functional and cosmetic results, and the flexor and extensor muscle strengths were measured and compared with the contralateral extremities. There were no statistical differences between the groups. The V-splitting posterior approach is as safe and effective as the lateral approach in the surgical treatment of pediatric supracondylar humeral fractures...
