Developmental dysplasia of the hip (DDH) is a relatively common malady that has profound consequences in the infant if left untreated. Effective and early treatment of DDH has been praised as one of the most successful ventures of modern pediatric orthopedics. Yet, before the modern management of DDH came into existence, there were extensive technological developments in the field of harnesses, casts, and traction methods. This paper aims to identify the centuries-old history of advancement in DDH treatment and the many important people involved...

Medial femoral torsion (MFT) is a common pathologic gait in cerebral palsy (CP) children that can be corrected by femoral derotational osteotomy (FDO). It is not clearly known as to how much various gait parameters change after FDO. The aim of this study was to quantify changes in gait parameters after FDO. The study group included 19 young CP patients (28 limbs, age<20 years, average age: 13.2 years) with symptomatic MFT, treated with distal FDO. The study group was divided into two groups: the unilateral FDO group (UG) and the bilateral FDO group (BG)...

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...

Secondary limb lengthening after intercalary bone resection in pediatric patients is still challenging. After the resection, a free fibula autograft can be used to reconstruct the osseous gap. However, in particular in young pediatric patients, insufficient growth of the epiphyseal plate after transplantation may lead to a significant limb-length discrepancy (LLD). In this case, the autograft was used for limb lengthening. We report on the lengthening of a humerus regenerate after fibula autograft transplantation into a humeral defect in a pediatric/young adolescent patient...

When using elastic stable intramedullary nailing in children's distal radius shaft fractures, the surgical approach can either be lateral or dorsal. The aim of this article was to carry out a systematic review of the literature comparing the two types of approaches in terms of complications. An electronic search of databases was performed. Titles of articles were screened, and abstracts and full text were read. Data were extracted in terms of demographics and complications. The dorsal approach had a 2.6% rate of extensor pollicis longus tendon rupture, whereas the lateral approach had a 2...

The aim of this study was to determine whether persistent idiopathic toe walking leads to compensatory skeletal changes in the pediatric foot and ankle. Foot radiographs of children diagnosed with idiopathic toe walking and sex-matched and age-matched controls were retrospectively reviewed. Five blinded providers assessed the foot radiographs for skeletal changes to the ankle. The relationship between each measure and toe-walking status was examined. Providers observed radiographic evidence of skeletal changes of the talus in idiopathic toe walkers compared with controls, suggesting that persistent toe walking impacts the skeletal development of the talus...

The effect of a continuous intrathecal infusion of baclofen (CITB) was retrospectively studied in 19 ambulatory children with cerebral palsy (aged 12.4±4.9 years at CITB initiation). The mean clinical follow-up was 5.1±2.4 years and the mean follow-up gait analysis was 2.8±1.9 years. Spastic cerebral palsy diagnosis [14 (74%)] was most frequent. Most patients [11 (58%)] were Gross Motor Function Classification System level III. CITB significantly improved muscle tone and knee flexion at initial contact (P<0...

The aim of this study was to assess the impact of different sports on hip joint anatomic parameters in athletes. This was a cross-sectional study of eight male trampolinists, eight male weightlifters, and eight male volunteers enrolled in July 2014. Hip joint anatomic parameters were measured from plain radiographs taken at the level of the lesser trochanter center. Data were compared between groups using the χ-test or one-way analysis of variance with the Bonferroni post-hoc test. There were no significant differences among groups in age, height, or weight...

Vitamin D is an important component in musculoskeletal development and function in children. The aim of our study was to investigate vitamin D levels and tibiofemoral joint orientation angles in children. We performed a retrospective review on a consecutive series of children presenting with lower limb complaints. The children underwent an assessment of serum vitamin D level and full-length standing lower limb anteroposterior radiographs, and were divided into normal and deficient vitamin D groups. Tibiofemoral angles (TFAs) [lateral distal femoral angle (LDFA); medial proximal tibial angle (MPTA)] were measured by three independent observers and compared between the groups...

Thirty years after its description by Masquelet in 1986, this is the first systematic review aiming to critically evaluate the 'induced membrane technique' effectiveness in achieving bone union in children. Only six papers fulfilled our inclusion criteria (54 patients). The relatively small number of reported cases did not allow a formal meta-analysis. The tibia was the most involved bone. Most frequent aetiologies were congenital pseudoarthrosis and tumour resections. Although effective in achieving bone healing in ∼91% of the patients (bone defects ≤24 cm long), the induced membrane technique was associated with a high rate of complications (54% of patients)...

The aim of this paper is to report the outcomes and any complications with arthroscopic bioabsorbable nail fixation of tibial eminence fractures in skeletally immature patients. We retrospectively reviewed all surgically treated tibial eminence fractures treated by a single surgeon and seven patients were identified with a minimum 2-year follow-up. Mean deficits of flexion and extension were minimal. Satisfactory Tegner levels, Lysholm knee scores, and International Knee Documentation Committee subjective scores were reported...

Bilateral avascular necrosis (AVN) following postictal bilateral fracture neck of the femur is a rare occurrence. Here, we report a case of bilateral AVN of the femoral head following an asynchronous bilateral postictal fracture neck of the femur. A 16-year-old autistic boy presented with left hip pain following an episode of seizures and radiographs showed Delbet type II fracture neck of the left femur. This was treated by closed reduction and cancellous screw fixation and skeletal traction for 6 weeks. At 3 months, follow-up radiograph showed union of the fracture, but he had developed segmental AVN with collapse of the head...

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...

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)...

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...

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...

Radial head dislocation in multiple osteochondroma leads to functional impairment and cosmetic problems, and surgical intervention has not been successful to date, with high rates of redislocation. Simple correction of the longitudinal axis and distraction oste8ogenesis of the ulna without corrective osteotomy of the radius were performed within 1 year of radial head dislocation. The mean age of the patients was 7.2 years and the postoperative follow-up duration was 63.6 months. In all cases, the dislocated radial head was repositioned without surgical invention involving the radius...

Achieving adequate dorsiflexion in neglected clubfoot cases remains challenging. On a close observation of the Ponseti method, we have now made certain modifications from the standard Ponseti protocol. This has helped us improve functional results, as well as reduce the number of casts in this walking-age group. From March 2011 onward, we managed 62 neglected clubfeet in 41 patients with the modified protocol. All these patients were treated with serial weekly above-knee casts. The feet were assessed by Dimeglio and Pirani scorings, which were done every week...

Considering different surgical techniques for the fixation of osteochondral intra-articular fracture, the present study aimed to compare the efficacy of autologous fibrin glue and Kirschner wire (KW) on an osteochondral fracture in the left lateral condyle of Dutch rabbits with a control group. After 6 weeks, macroscopic and microscopic evaluation showed that autologous fibrin glue is easier and faster with a higher number of bone trabecula (P<0.05), whereas the healing rate and cellularity of the healing site were not different between the two groups (KW and glue)...

Proximal femoral osteotomy has been used in cerebral palsy, Perthes disease, hip dysplasia, idiopathic femoral anteversion, and various hip diseases in children and adolescents. Conventionally, a blade plate (BP) has been used. However, the pediatric locking compression plate (LCP) has recently been applied widely. We compared the hardware-related complications of the BP and the LCP as well as the factors influencing these complications in patients who have undergone a proximal femoral osteotomy in children and adolescents...
