Developmental Dysplasia of the Hip - Part 1.

Developmental dysplasia of the hip (DDH) is a condition characterized by changes in joint formation within the last months of intrauterine life or the first months after birth. Developmental dysplasia of the hip presentation ranges from femoroacetabular instability to several stages of dysplasia up to complete dislocation. Early diagnosis is essential for successful treatment. Clinical screening, including appropriate maneuvers, is critical in newborns and subsequent examinations during the growth of the child. Infants with suspected DDH must undergo an ultrasound screening, especially those with a breech presentation at delivery or a family history of the condition. A hip ultrasound within the first months, followed by pelvic radiograph at 4 or 6 months, determines the diagnosis and helps follow-up. Treatment consists of concentric reduction and hip maintenance and stabilization with joint remodeling. The initial choices are flexion/abduction orthoses; older children may require a spica cast after closed reduction, with or without tenotomy. An open reduction also can be indicated. After 18 months, the choices include pelvic osteotomies with capsuloplasty and, eventually, acetabular and femoral osteotomies. The follow-up of treated children must continue throughout their growth due to the potential risk of late dysplasia.

TREATMENT OF OSTEOGENESIS IMPERFECTA USING THE FASSIER-DUVAL TELESCOPIC ROD.

Objectives: This study aimed to assess the treatment of patients with Osteogenesis Imperfecta (OI) operated on with a telescopic Fassier-Duval (FD) rod in a querterenario hospital from 2010 to 2020. Methods: We analyzed indication for surgical treatment, causes of reoperation, complications and the effectiveness of telescoping rod. Results: The results were compared with the literature and with the same parameters from a previous study which a different telescopic rod developed by the same authors. This was a retrospective study based on the analysis of digital and radiographic clinical records. Fifteen patients with 21 FD rods were evaluated, most were used on the femur (18 rods or 85.7%), eight patients were female (53.3%), with a mean age of 10.47 (3.92 to 16.44) years, most of whom had type III Sillence (46.7%), with a mean follow-up of 5.22 (1.43 to 7.02) years. Seven rods (33.3%) had complications. The main indication was for fracture (57.1%). Regarding the ability to telescope, we observed that 15 rods (71.4%) followed the child's growth. Conclusion: We had good results using FD rods, similar to the data found in the literature and the data obtained with our rod. Level of Evidence III,Retrospective comparative study .

Resumo O termo displasia do desenvolvimento quadril (DDQ) refere-se à condição na qual a articulação sofre alterações na sua formação durante os últimos meses da vida intrauterina ou nos primeiros meses após o nascimento. No espectro de apresentação, varia desde a instabilidade femuroacetabular, passando por estádios de displasia até a completa luxação. O diagnóstico precoce é fundamental para o sucesso do tratamento. A triagem através do exame clínico incluindo manobras apropriadas é imprescindível nos recém-nascidos e nas avaliações subsequentes durante o crescimento da criança. O rastreamento ultrassonográfico é indicado nos bebês sob suspeita clínica e muito mais recomendável naqueles que tiveram apresentação pélvica para o parto ou que tenham antecedentes familiares. A ultrassonografia do quadril nos primeiros meses seguida da radiografia da bacia após o 4° ou 6° mês de vida são os exames que determinam o diagnóstico e auxiliam o seguimento. O tratamento está baseado na obtenção de uma redução concêntrica e na manutenção e estabilização do quadril, propiciando a remodelação articular. Inicialmente, as órteses de flexão/abdução são a escolha; em crianças maiores pode ser necessário o uso de gesso após redução incruenta com ou sem tenotomia; redução aberta pode ser indicada e após os 18 meses as osteotomias pélvicas associadas a capsuloplastia e eventuais osteotomias acetabular e femoral. Crianças tratadas devem ser acompanhadas durante todo o seu crescimento pelo eventual risco de displasias tardias.

Percutaneous hemiepiphysiodesis using transphyseal screws for adolescent tibia vara.

Hemiepiphysiodesis around the knee is becoming the mainstay procedure in adolescents for a wide range of aetiological deformities, when considering adolescent tibia vara (ATV), the published series have variable results. The purpose of this study was to review our experience with the percutaneous transphyseal screw (PETS) in these patients followed until bone maturity. We analysed the charts from 13 patients (20 knees) that underwent lateral tibial hemiepiphysiodesis using PETS. The radiographs were accessed before surgery, at implant removal, when occurred, and at the final follow-up. The clinical evaluation noted if there were complaints regarding pain or range of motion, and the radiographic assessment included: the femorotibial angle, the mechanical axis zone, the anatomic lateral distal femoral angle, and medial mechanical proximal tibial angle. There was one overcorrection, and after the screw removal (14 knees), rebound was observed in two knees modifying the result from excellent to good in all three knees. No bone bars and no implant breakage were observed. At the last appointment, all patients had normal knee range of motion, and two patients had unilateral alignment complaints, one of whom referred to occasional pain. Overall, the surgery was excellent in 12 knees (60%), good in six knees (30%), and poor in two knees (10%). This technique is indicated to be well tolerated and effective for treating ATV. When a complete correction cannot be obtained, in our opinion, it is advantageous to at least stabilise the deformity and postpone osteotomies until after skeletal maturity. Level of Evidence: Level IV - Case Series, Therapeutic Study.

THE EPIDEMIOLOGY OF DEVELOPMENTAL DYSPLASIA OF THE HIP IN MALES.

Developmental Dysplasia of the Hip (DDH) is one of the most common orthopedic hip diseases of the pediatric population. There is a predominance in females and patients with known risk factors. OBJECTIVE: To evaluate the characteristics of DDH in a reference center and compare them with the literature. METHODS: This is a cross-sectional observational study based on the review of medical records and radiographs from which epidemiological data such as laterality, age at diagnosis, acetabular index, radiographic classification and others were collected. RESULTS: A total of 297 medical records were found between May 1974 and June 2009. Of those, 147 patients (216 affected hips) were eligible for the survey. Most of the patients came from the state of São Paulo (91.1%), were born in autumn/winter (66.7%), reported as Caucasians (76.9%), with bilateral involvement (46.9%) and mean age at diagnosis of 22.8 months. CONCLUSION: The most frequent type of DDH was high dislocation (28.7%), and the acetabular index progressively increased with the age. The International Hip Dysplasia Institute classification was found to be more reproducible than Tönnis classification. Delayed diagnosis was associated with the absence of risk factors and with bilaterality. Level of Evidence III, Retrospective comparative study.

Medial hip arthroscopy portals: a novel approach for hip pathologies. Is it feasible?

PURPOSE: To report 3 patients operated on using medial hip arthroscopic portals, describe the surgical technique and clinical outcomes. METHODS: Three medial portals were made, the first one at the posterior edge of the adductor longus muscle (posterior medial portal), the second one at the anterior (anterior medial portal) and the third at the posterior border of the adductor longus, 5 cm distal to the inguinal crease (distal posterior medial portal). The first case was an 8-year-old boy with a lytic lesion at the posteromedial region of the femoral neck suggestive of sub-acute osteomyelitis. The second patient was a 21-year-old male with a posteromedial femoral neck nidus. The third patient was a 42-year-old male with a posteromedial femoral neck cystic lesion. CONCLUSIONS: The described portals allowed successful access to posteromedial femoral neck. There were no neurovascular lesions, infection, femoral head osteonecrosis, skin retraction or functional limitation related to the portals.

Pelvic injury in childhood: what is its current importance?

OBJECTIVE: The purpose of this study was to assess the importance of pelvic fractures in childhood by analyzing epidemiological characteristics and associated injuries. METHODS: This is a retrospective study performed between 2002 and 2012 at two trauma referral centers in São Paulo. We identified 25 patients aged 16 years old or younger with pelvic fracture. RESULTS: The main mechanism of trauma was traffic accident (80%), followed by fall from height (16%). At hospital admission, 92% had traumatic brain injury and 40% had hemodynamic instability. Besides pelvic fractures, 56% of the children had other associated injuries (genitourinary, abdominal, vascular, chest and neurological), and 79% of them required operative treatment. According to the Torode and Zieg classification, the majority of cases were types III and IV. Seventy-two percent of all pelvic fractures were treated by surgery; 52% involved external fixation and 20% involved open reduction and internal fixation. CONCLUSIONS: The pelvic fractures in childhood can be considered a marker for injury severity, because the associated injuries usually are severe, needing operative treatment and leading to a high mortality rate (12%). Level of Evidence IV, Case Series

Roentgenographic Evaluation of the Spine in Patients With Osteogenesis Imperfecta.

Osteogenesis imperfecta (OI) is a hereditary connective tissue disorder that leads to bone weakness and deformities, especially in the spine, which can lead to poor outcomes.The aim of this study was to find patterns and risk factors in spinal deformities in patients with OI.In a retrospective study, 70 patients with OI were selected. Radiographs of the spine were evaluated. We observed the presence or absence of the following changes: biconcave vertebrae, chest and vertebral deformities, unilateral rib, and thoracolumbar kyphosis. The greater curve was considered the primary one, and the secondary curve considered compensatory.In the study sample, we observed that the patients' ages ranged between 7 and 50 years, with a mean equal to 13 years, and 76% had scoliosis. In 68% of cases the main curve in the thoracic region was observed with the convexity to the right.The following was found in patients with OI: scoliosis, biconcave vertebrae, vertebral and chest deformity, unilateral rib, and thoracolumbar kyphosis. The thoracolumbar kyphosis is highly associated with thoracic hypokyphosis in patients with OI.

Chronic slipped capital femoral epiphysis: a radiographic evaluation of the Southwick osteotomy.

The aim of this study was to evaluate the radiographic correction and the complications in Southwick osteotomy for slipped capital femoral epiphysis (SCFE) on the basis of radiographic evaluation. We retrospectively analyzed the charts of 37 patients with chronic, unilateral, moderate, or severe SCFE, who underwent the procedure, verifying Southwick angles, articulotrochanteric distance, and the articular narrowing on preoperative, postoperative periods, and in the last follow-up evaluation, using the contralateral, healthy hip, for comparison. Southwick's angle changed from 117.8 to 147.3° on average (front) and from 56.9 to 19.1° (Lauenstein view). Articulotrochanteric distance changed from 11.3 to 24.1 mm (normal distance 22.1 mm). Joint space changed from 4.3 mm preoperatively to 3.84 mm. Chondrolysis was diagnosed in five cases before and eight cases after surgery. There was no case of avascular necrosis. Southwick osteotomy effectively corrected SCFE deformity. There was a tendency toward excessive valgism.

Accidents due to falls from roof slabs.

CONTEXT AND OBJECTIVE Falls from the roof slabs of houses are accidents of high potential severity that occur in large Brazilian cities and often affect children and adolescents. The aims of this study were to characterize the factors that predispose towards this type of fall involving children and adolescents, quantify the severity of associated lesions and suggest preventive measures. DESIGN AND SETTING Descriptive observational prospective longitudinal study in two hospitals in the metropolitan region of São Paulo. METHODS Data were collected from 29 cases of falls from roof slabs involving children and adolescents between October 2008 and October 2009. RESULTS Cases involving males were more prevalent, accounting for 84%. The predominant age group was schoolchildren (7 to 12 years old; 44%). Leisure activities were most frequently being practiced on the roof slab at the time of the fall (86%), and flying a kite was the most prevalent game (37.9%). In 72% of the cases, the children were unaccompanied by an adult responsible for them. Severe conditions such as multiple trauma and traumatic brain injuries resulted from 79% of the accidents. CONCLUSION Falls from roof slabs are accidents of high potential severity, and preventive measures aimed towards informing parents and guardians about the dangers and risk factors associated with this type of accident are needed, along with physical protective measures, such as low walls around the slab and gates with locks to restrict free access to these places.

Flexible intramedullary nails with traction versus plaster cast for treating femoral shaft fractures in children: comparative retrospective study.

CONTEXT AND OBJECTIVE Femoral fractures are common in children between 2 and 12 years of age, and 75% of the lesions affect the femoral shaft. Traction followed by a plaster cast is universally accepted as conservative treatment. However, in some situations, a surgical approach is recommended. The objective here was to compare treatments for femoral shaft fractures using intramedullary nails (titanium elastic nails, TEN) versus traction and plaster casts in children. The hypothesis was that TEN might provide better treatment, with good clinical results in comparison with plaster casts. DESIGN AND SETTING This retrospective comparative study was conducted in a public university hospital. METHODS Sixty children with femoral fractures were evaluated; 30 of them underwent surgical treatment with TEN and 30 were treated conservatively using plaster casts. The patients' ages ranged from 5 to 13 years (mean of 9 years). RESULTS The mean duration of hospitalization was nine days for the surgical group and 20 days for the conservative group. The incidence of overgrowth in the patients treated with TEN was 60.0% and, for those treated conservatively, 13.3%. Partial weight-bearing was allowed after 3.5 weeks in the surgical group and after 9.6 weeks in the conservative group. New hospitalization was required for 90.0% in the surgical group and 16.7% in the conservative group. Patients treated with plaster casts presented higher incidence of complications, such as loss of reduction. CONCLUSIONS The surgical method presented better results for children.

Fraturas femorais são comuns em crianças entre 2 e 12 anos de idade, e 75% das lesões acometem a diáfise. Tração seguida de aparelho gessado (“gesso”) é universalmente aceita como tratamento conservador. Entretanto, em algumas situações o tratamento cirúrgico é recomendado. O objetivo foi comparar o tratamento de fraturas diafisárias do fêmur com hastes intramedulares (titanium elastic nails, TEN) com tração e gesso em crianças. A hipótese era de que TEN pode ser melhor tratamento, com bons resultados clínicos em comparação com o gesso.

Este estudo retrospectivo e comparativo foi conduzido num hospital público universitário.

Sessenta crianças com fraturas de fêmur foram avaliadas, 30 delas foram submetidas a tratamento cirúrgico com TEN e 30 foram tratadas de forma conservadora usando gesso. A idade dos pacientes variou de 5 a 13 anos (média de 9 anos).

O tempo médio de internação foi de 9 dias para o grupo cirúrgico e 20 dias para o grupo conservador. A incidência de crescimento excessivo nos pacientes tratados com TEN foi de 60,0% e, para aqueles tratados de forma conservadora, 13,3%. Sustentação parcial de peso foi permitida após 3,5 semanas no grupo cirúrgico e após 9,6 semanas no grupo conservador. Houve 90,0% de novas internações no grupo cirúrgico e 16,7% no grupo conservador. Pacientes tratados com gesso apresentaram maior incidência de complicações, tais como perda de redução.

Hastes intramedulares flexíveis: uma alternativa de tratamento para cisto ósseo simples no colo do fêmur / Flexible intramedullary nails: an alternative treatment for simple femoral neck cyst "

O cisto ósseo simples é uma lesão osteolítica geralmente diagnosticada na primeira e 2ª década de vida, frequentemente assintomática e comum no úmero e no fêmur proximal. O tratamento clássico desta lesão inclui abertura do cisto com curetagem e enxerto ósseo e injeção percutânea com acetato de metilprednisolona. Entretanto, essas técnicas apresentam um alto índice de recorrência e associação com complicações. Nós descrevemos o caso de uma criança de oito anos, sexo feminino, que procurou nosso serviço com queixa de dor no quadril direito e claudicação há 15 dias. Nos exames radiográficos foi evidenciando uma imagem lítica de bordos bem definidos no colo do fêmur, com afinamento da cortical medial e apresentando risco iminente de fratura. A paciente foi submetida à intervenção cirúrgica de fixação retrógrada com duas hastes intramedulares flexíveis, aspiração e infiltração do cisto com acetato de metilprednisolona. Apesar de não ter ocorrido à consolidação completa aos 12 meses de acompanhamento, houve benefícios para a paciente com a mobilização e retorno as atividades precocemente.
