Effect of Total Hip Arthroplasty with Ceramic Acetabular Component on Clinical, Radiographic and Functional Parameters in Older Patients with Hip Osteoarthritis: Two-Year Follow-Up.

Background: Total hip arthroplasty (THA) is a widely used surgical procedure to reduce pain and improve function and quality of life in patients with hip disorders. The most common condition that leads to THA is osteoarthritis, with most surgeries being performed to treat severe osteoarthritis with pain and functional limitations. Despite the evident success of THA, the search for its improvement and better results, especially in the long term, continues, especially in older patients, for which there is still little scientific evidence. Objective: To evaluate the clinical, radiological, and functional aspects preoperatively and two years after THA with a ceramic acetabular component device in older patients with hip osteoarthritis. Methods: A retrospective cohort study was conducted to evaluate 65 older individuals who underwent THA of the hip with an acetabular component (MD® ceramic head with a ceramic acetabular insert) associated with the MD6® Phenom® femoral rod type, in Hospital of the Luz, São Paulo/SP, between 2018 and 2019. Anthropometric and clinical information about the operative procedure and two years follow-up were collected from the patients' medical records. For the clinical-functional evaluation, the Harris Hip Score (HHS) questionnaire and hip movement goniometry were applied. For the radiographic parameters, the following were evaluated: the positioning of the acetabular component, the Zone of DeLee and the offset of the femoroacetabular component. Results: There was a higher prevalence of performing THA in males (53.8%). Preoperative and two-year postoperative radiographic parameters of surgical treatment for THA showed maintenance of the acetabular (p = 0.083) and femoral (p = 0.102) positioning angles and increased functionality (p < 0.001) and joint mobility of the hip (p = 0.001) with reduced pain after two years of THA. Complications related to dislocation, loosening, infection, and inadequate positioning of the implant were low, ranging from 1.5 to 3%. Conclusion: Older people who underwent cementless THA with an ceramic acetabular component device, in a two-year follow-up, showed effectiveness in improved clinical, radiological, and functional aspects.

Effect of progression of adolescent idiopathic scoliosis on gait parameters / Efeito da progressão da escoliose idiopática do adolescente sobre os parâmetros da marcha / Efecto de la progresión de la escoliosis idiopática del adolescente sobre los parámetros de la marcha

ABSTRACT Objectives: To evaluate the influence of the degree of severity of adolescent idiopathic scoliosis (AIS) on the distribution of plantar load on the feet during gait. Material and Methods: 40 patients with AIS were evaluated and divided into severity groups: 13 with mild AIS; 13 with moderate AIS; and 14 with severe AIS. Cobb angles (degrees) were evaluated by radiography. Gait was assessed using the pressure platform at a frequency of 100 Hz. The adolescents walked on a 20-meter track, with their feet resting on the platform, totaling an average of 12 steps. The following were evaluated: contact area, peak pressure, and maximum force on the 4 regions of the feet: hindfoot (medial and lateral), midfoot, and forefoot. Results: Adolescents with moderate and severe AIS showed an increase in peak pressure and maximum force on the medial (p=0.014; p=0.045, respectively) and lateral (p=0.035; p=0.039, respectively) hindfoot and a reduction on the midfoot (p=0.024) when compared to mild AIS. The contact area showed no differences between groups. Conclusion: The moderate and severe degree of AIS severity promoted increased plantar load on the medial and lateral hindfoot (heel) during gait compared to adolescents with a mild degree of scoliotic curvature. In this way, gait training in the milder stages of disease severity can minimize the overload and the increase in force vectors on the spine, preventing the progression of severe scoliotic curvature. Level of Evidence II; Cross-sectional study.

Resumo: Objetivos: Avaliar a influência do grau de severidade da escoliose idiopática do adolescente (EIA) sobre a distribuição da carga plantar dos pés durante a marcha. Material e Métodos: 40 pacientes com EIA foram avaliados e divididos em grupos de severidade: 13 com EIA leve; 13 com EIA moderada; e 14 com EIA grave. Os ângulos de Cobb (graus) foram avaliados pela radiografia. A marcha foi avaliada pela plataforma de pressão, a uma frequência de 100 Hz. Os adolescentes caminhavam sobre uma pista de 20 metros, com o registo do apoio dos pés sobre a plataforma, totalizando em média 12 passos. Foram avaliadas área de contato, pico de pressão e força máxima sobre as 4 regiões dos pés - retropé (medial e lateral), mediopé e antepé. Resultados: Os adolescentes com EIA moderada e grave mostraram um aumento do pico de pressão e força máxima sobre o retropé medial (p=0,014; p=0,045, respectivamente) e lateral (p=0,035; p=0,039, respectivamente) e uma redução sobre o mediopé (p=0,024) quando comparados a EIA leve. Não houve diferenças quanto a área de contato entre os grupos. Conclusão: O grau de severidade moderada e grave da EIA promoveu um aumento da carga plantar sobre retropé medial e lateral (calcanhar) durante a marcha em comparação aos adolescentes com grau leve da curvatura escoliótica. Desta forma, o treino de marcha nos estágios mais leve de severidade da doença pode minimizar a sobrecarga e o aumento dos vetores de força sobre a coluna, evitando a progressão da curvatura escoliótica grave. Nível de evidência II; Estudo transversal.

Correlation between cyphose and lordose with the foot support of adolescents with idiopathic scoliosis / Correlação entre cifose e lordose com o apoio dos pés de adolescentes com escoliose idiopática / Correlación entre cifosis y lordosis con el soporte de los pies de adolescentes con escoliosis idiopática

ABSTRACT: Objective: To verify the correlation between the thoracic and lumbar Cobb angle and the type of foot, and the parameters of plantar support during gait in adolescents with idiopathic scoliosis. Material and Methods: Sixty adolescents with idiopathic scoliosis (AIS) were divided into three groups: normal foot (n=20), cavus foot (n=20), and flat foot (n=20). The Cobb angles of thoracic kyphosis and lumbar lordosis were evaluated by radiographic examination. The plantar arch was recorded the podoscope and calculated by the ratio between the midfoot and the total foot area. The adolescents performed the march on a 20-meter track, with their feet resting on the pressure platform, totaling an average of 12 steps of the foot (right and left). The variables evaluated were: contact area, peak pressure, and maximum force on the four regions of the feet: hindfoot (medial and lateral), midfoot, and forefoot. Results: There was a positive correlation between the Cobb angle of lumbar lordosis and the arch plantar cavus (r=0.40; p=0.048) and flat (0.25; p=0.004), with no significant correlations for the Cobb angle thoracic (p>0.005). The pressure peak strongly correlated with the cavus plantar arch (r=0.92, p=0.001) in the lateral hindfoot and forefoot region, while the flat foot with the midfoot region. Conclusion: The Cobb lumbar lordosis angle positively correlates with the plantar arch height and the plantar support pattern during gait in adolescents with idiopathic scoliosis.

L5 Radiculopathy After Formal Reduction of High-Grade SDSG Type 5 and 6 L5-S1 Isthmic Spondylolisthesis with 2-Year Follow-Up.

BACKGROUND: Surgery is the main treatment for patients with high-grade L5-S1 isthmic spondylolisthesis, which can result in neurologic complications, but little is known about its clinical course. The present study evaluated the presence of L5 radiculopathy in high-grade L5-S1 spondylolisthesis in adults in pre- and postoperative periods and after a 2-year follow-up. METHODS: A series of 16 patients who underwent reduction and instrumented fusion for high-grade 5 and 6 spondylolisthesis between 2018 and 2019 were retrospectively evaluated in the pre- and postoperative periods as well as after 6 weeks, 3 months, 6 months, and 1 and 2 years of follow-up. Clinical and surgical data on possible neurological complications of L5 radiculopathy were prospectively collected. RESULTS: The age was 20.1 ± 12.0 years, and preoperative L5-S1 slip was 89.0%. Five patients presented motor deficit in the preoperative period. In the immediate postoperative period, 9 patients (56%) experienced motor deficits or worsening of the preoperative condition. At the 6-week follow-up, only 1 patient showed resolution of the motor deficit. Three patients presented healed motor deficits after 3 months, and 1 patient demonstrated a healed L5 motor radiculopathy after 6 months. At the 1-year follow-up, only 1 patient exhibited an L5 radiculopathy motor deficit, and at the 2-year follow-up, none of the patients exhibited an L5 radiculopathy motor deficit. CONCLUSION: L5 radiculopathy was frequent in the preoperative period and increased after reduction and instrumented fusion of high-grade L5-S1 spondylolisthesis in the postoperative period and in the 6-week follow-up. Three and 6 months after the surgery, there were consecutive motor improvements. After 2 years of follow-up, no patients showed neurological deficit of L5 radiculopathy. LEVEL OF EVIDENCE: 2. CLINICAL RELEVANCE: This is the first study reporting a reduction in complications of L5 neurological motor deficit over a 2-year follow-up in high-grade L5-S1 spondylolisthesis in young adults.

The effect of direct vertebral rotation on the spine parameters (coronal and sagittal) in adolescent idiopathic scoliosis.

BACKGROUND: Idiopathic scoliosis is accompanied by postural alterations, instability of gait, and functional disabilities. The objective was to verify radiographic parameters (coronal and sagittal) of adolescents with idiopathic scoliosis (AIS) pre- and post-surgery with direct vertebral rotation (DVR), associated with type 1 osteotomies in all segments (except the most proximal) and type 2 in the periapical vertebrae of the curves. METHODS: A prospective study design was employed in which 41 AIS were evaluated and compared pre- and post-surgery. Scoliosis was confirmed by a spine X-ray exam (Cobb angle). Eight radiographic parameters were measured: Cobb angles (thoracic proximal and distal), segmental kyphosis, total kyphosis, lumbar lordosis, pelvic incidence, sacral slope, and pelvic tilt. RESULTS: The Cobb angle averaged 51.3∘± 14.9∘. Post-surgery, there were significant reductions for the following spine measurement parameters: Cobb angle thoracic proximal (p= 0.003); Cobb angle thoracic distal (p= 0.001); Cobb angle lumbar (p= 0.001); kyphosis (T5-T12, p= 0.012); and kyphosis (T1-T12, p= 0.002). These reductions showed the effectiveness of surgical correction to reduce Cobb angles and improve thoracic kyphosis. The values obtained for lumbar lordosis, pelvic incidence, sacral slope, and pelvic tilt were not significantly different pre- and post-surgery. CONCLUSION: The surgical technique of DVR in AIS proved to be effective in the coronal and sagittal parameters directed at Cobb angles and thoracic kyphosis in order to favor the rehabilitation process.

Treatment of two-part fractures of the surgical neck of the humerus using a locked metaphyseal intramedullary nail proximally with angular stability.

OBJECTIVES: To evaluate the functional results from patients with surgical neck fractures treated with a locked metaphyseal intramedullary nail and angular stability. METHODS: Twenty-two patients between the ages of 21 and 69 years were evaluated prospectively between January 2010 and January 2011. Their time taken for consolidation, age, sex, complications and functional results were correlated using the modified protocol of the University of California at Los Angeles (UCLA). RESULTS: The mean time taken for consolidation was 9.26 weeks ± confidence interval (CI) of 0.40 weeks. One case (4.5%) did not become consolidated. There were no cases of infection. There was one case (4.5%) of adhesive capsulitis with good evolution through clinical treatment. Five patients (22.7%) presented occasional mild pain and one case (4.5%) reported medium-intensity pain associated with the subacromial impact of the implant. The mean score on the modified UCLA scale was 30.4 ± CI 1.6 points, obtained at the end of 12 weeks of evaluation: 18 cases (81.8%) with "excellent" and "good" scores, three cases (13.6%) with "fair" scores and one case (4.5%) with a "poor" score. CONCLUSION: In the group of patients evaluated, treatment of two-part surgical neck fractures by means of a locked metaphyseal intramedullary nail and angular stability demonstrated satisfactory functional results and a low complication rate, similar to what is seen in the literature.

Interlocking screws placed with freehand technique and uni-planar image intensification: the "dip-stick" technique.

OBJECTIVE: To report our experience with a novel alternative method of freehand interlocking of intramedullary nails. This method requires the use of only anterior-posterior image intensification and an intramedullary guide wire to verify screw placement. Our results are compared with historical results in the literature. METHODS: A total of 815 patients were treated using this technique from January 2008 to December 2012; 603 patients had fractures of the tibia and 212 had fractures of the femur. RESULTS: The mean duration of surgery for tibial shaft fractures was 55.6 minutes (range 42-60 minutes) and that for fractures of the femur was 78 minutes (range 50-90 minutes). The mean time for each distal locking was 3.8 minutes (2.5-5.1 minutes), with 7.65 seconds of exposure to radiation during each block. CONCLUSIONS: The surgical technique is simple, easy and reproducible. Mean time of surgery and radiation exposure was less than that in the literature. A comparative study should be performed.
