Objective:To evaluate the effect of the impaction of posterior wall on the prognosis following open reduction and internal fixation for fractures of acetabular posterior wall.Methods:A retrospective study was conducted to analyze the data from the 83 patients with fracture of acetabular posterior wall who had been consecutively treated by open reduction and internal fixation at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2017 to December 2020. The patients were divided into 2 groups based on involvement of posterior wall impaction. In the impaction group of 33 cases, there were 26 males and 7 females with an age of (47.4±11.6) years; in the non-impaction group of 50 cases, there were 43 males and 7 females with an age of (41.3±12.0) years. The quality of postoperative fracture reduction, the function of the affected hip at the last follow-up, and the complication rate during follow-up were compared between the 2 groups. Multifactorial binary logistic regression and age subgroups were used to analyze the effects of posterior wall impaction on functional outcomes.Results:The age, rate of associated injuries in other body parts, and rate of posterior wall comminution in the impaction group were significantly higher than those in the non-impaction group ( P<0.05), but there was no statistically significant difference in other general data of patients between the 2 groups ( P>0.05). All patients were followed up for (44.5±13.3) months after surgery. The rate of anatomical reduction in the non-impaction group (96.0%, 48/50) was significantly higher than that in the impaction group (57.6%, 19/33) ( P<0.05), and the good and excellent rate by the modified Merle d'Aubigné & Postel scale at the last follow-up in the non-impaction group (84.0%, 42/50) was significantly higher than that in the impaction group (51.5%, 17/33) ( P<0.05). There was no significant difference in the incidence of complications between the 2 groups ( P>0.05). After adjusting for age and gender, the difference in hip function was still significantly different between the 2 groups ( OR=0.23, 95% CI: 0.06 to 0.79, P=0.020). The effect of posterior wall impaction on functional outcomes was statistically significant in patients aged ≥50 years ( P=0.008), whereas the difference was not statistically significant in patients aged <50 years ( P=0.194). Conclusions:Compared with non-impaction ones, acetabular fractures of posterior wall impaction tend to lead to poorer quality of reduction, which in turn affects the postoperative recovery of hip joint function. The impact of impaction fractures on functional recovery is more significant in patients aged 50 years and above.

Objective:To investigate the effectiveness of the modified Bikini approach in the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate.Methods:A retrospective study was conducted to analyze the data of 54 patients with acetabular fracture who had been treated at Department of Trauma Orthopedics, Orthopedic Medical Center, The Third Hospital Affiliated to Southern Medical University from May 2017 to June 2021. The patients were divided into 2 groups based on different surgical approaches: an observation group [26 cases, 6 males, 20 females; aged 40.0 (29.8, 46.8) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the modified Bikini approach, and a control group [28 cases, 10 males, 18 females; aged 34.5 (24.0, 43.5) years] treated with fixation with an integrated wing-shaped anatomical locking plate through the lateral-rectus approach. The incision length, operation time, intraoperative bleeding, length of hospital stay, quality of postoperative fracture reduction, visual analog scale (VAS) for pain, hip function, Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS) were compared between the 2 groups.Results:The differences in the preoperative general data between the 2 groups were not statistically significant, indicating comparability ( P>0.05). There were no statistically significant differences between the 2 groups either in terms of incision length, operation time, intraoperative bleeding, or hospital stay ( P>0.05). The 2 groups were not significantly different in the excellent/good rate of fracture reduction [100.0% (26/26) versus 92.9% (26/28)], VAS at 1 month postoperation [2.0(1.0, 3.0) versus 2.0(1.0, 3.0)], or the modified Merle d'Aubigné and Postel hip score at 12 months postoperation [13.5(12.3, 14.8) versus. 14.0(13.0, 15.0)] ( P>0.05). However, the VSS [4.50(4.00, 6.00)] and POSAS (29.85±10.05) at 12 months postoperation in the observation group were significantly lower than those in the control group [6.50(5.00, 8.25) and 37.11±11.75] ( P<0.05). Conclusion:In the fixation of acetabular fracture with an integrated wing-shaped anatomical locking plate, the modified Bikini approach can not only achieve as fine early clinical efficacy as the lateral-rectus approach, but also demonstrate the aesthetic advantages of smaller incision scar and more hidden incision.

Objective:To investigate the surgical outcomes of acetabular posterior wall fractures in patients aged 50 and above.Methods:A retrospective study was conducted to analyze the clinical data of 67 patients with acetabular posterior wall fracture who had been treated through the Kocher-Langenbeck approach and fully followed up from August 2003 to November 2021. There were 54 males and 13 females, aged 59.0 (54.0, 63.0) years. The time from injury to surgery was 8.0 (5.0, 13.0) days. Open reduction and internal fixation was performed for 63 cases and hip arthroplasty for 4 cases by one stage. The operation time, intraoperative bleeding, quality of postoperative fracture reduction, recovery of hip function at the last follow-up, and incidence of complications during the follow-up period were recorded.Results:The operation time for the 67 patients was 90.0 (67.5, 101.3) min, and the intraoperative bleeding 350.0 (300.0, 450.0) mL. According to the Matta criteria, 63 patients with internal fixation achieved anatomical reduction. All the 67 patients were followed up for (112.8±62.4) months. According to the modified Merle d'Aubigné & Postel scoring system, the function of the affected hip was assessed at the last follow-up in the 63 patients with internal fixation as excellent in 56 cases, as good in 3 cases, as fair in 2 cases, and as poor in 2 cases, giving an excellent and good rate of 93.6% (59/63). The prostheses survived in all the 4 patients who underwent one-stage hip replacement, with hip Harris scores of 94, 92, 91, and 93, respectively. Complications included 15 cases (23.8%, 15/63) of heterotopic ossification and 1 case (1.6%, 1/63) of transient sciatic nerve palsy. Femoral head ischemic necrosis and traumatic arthritis occurred in 2 patients (3.2%, 2/63) who had to receive total hip arthroplasty 3 years after surgery.Conclusion:Open reduction and internal fixation is still the main treatment method for acetabular posterior wall fractures in patients aged 50 and above, because it can achieve good clinical outcomes and help the patients recover joint function and quality of life at an early stage.

Objective:To compare the parameters for infra-acetabular screw placement between men and women using a digital Chinese anatomical model of the pelvis and acetabulum.Methods:The normal pelvic CT data were collected from the 163 adult patients who had been admitted to the Traditional Chinese Medicine Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2021. There were 61 males and 102 females with an age of 53.0 (45.0, 60.0) years. Mimics 21.0 software was used to reconstruct the three dimensional pelvis which was then imported into Autodesk maya 2022 software before the model was flattened. Polygonal modeling tools were used to create a cylinder to simulate an infra-acetabular screw for length and angle measurements of the screw. The diameters of the infra-acetabular screws were measured by axial fluoroscopy in Mimics 21.0 software. The maximum diameters and maximum lengths of the infra-acetabular bone channel were compared between males and females, and the angles between the axis of the infra-acetabular screw and the anterior pelvic plane and the median sagittal plane were also compared between genders.Results:The maximum diameters of the left and right infra-acetabular corridors were 5.24 (4.26, 6.38) mm and 5.04 (4.50, 6.57) mm in males, and 3.99 (3.81, 4.51) mm and 3.89 (3.65, 4.90) mm in females; the maximum lengths of the left and right infra-acetabular corridors were (98.43±4.42) mm and (98.01±5.08) mm in males and 87.73 (84.22, 90.98) mm and 87.51 (84.59, 90.15) mm in females. The left and right angles between the infra-acetabular screw axis and the median sagittal plane were -0.98°±4.79° and -1.08°±4.91° in men, and 6.20° (3.34°, 11.16°) and 6.44° (3.77°, 11.85°) in women. The differences in the above data between men and women were statistically significant ( P<0.05). There was no statistically significant difference between men and women in the angle between the infra-acetabular screw axis and the anterior pelvic plane ( P>0.05). Conclusions:The length and diameter of the infra-acetabular corridor in males are greater than those in females, the angle between the infra-acetabular corridor and the sagittal plane in males is smaller than that in females, and the infra-acetabular corridor in males is more parallel to the sagittal plane. Therefore, the fluoroscopy angle should be adjusted for males to reduce the difficulty in screw placement when an infra-acetabular screw is placed during surgery.

Objective:To investigate the efficacy and safety of nerve decompression surgery through the lateral-rectus approach for sacral plexus nerve injury after sacral fracture fixation.Methods:A retrospective study was conducted to analyze the 10 patients with combined sacral plexus nerve injury after sacral fracture fixation who had been admitted to Department of Orthopedics, Xiangya Hospital between May 2022 and May 2023. There were 2 males and 8 females with an age of 16.5 (15.0, 26.3) years. At the time of injury, the patients had been clearly diagnosed as sacral fracture combined with sacral plexus nerve injury. By the Denis classification of sacral fractures: 7 cases of type Ⅱ and 3 cases of type Ⅲ; sacral plexus nerve injury sites: 1 case of L 4, 8 cases of L 5, 7 cases of S 1, and 2 cases of S 2. All of them were treated with reduction and internal fixation via the posterior approach within 2 weeks after injury, but after surgery their manifestations of sacral plexus nerve injury still persisted which were confirmed by CT, magnetic resonance imaging and neuromuscular electromyography. Therefore, at (4.0±2.3) months after internal fixation, all patients were treated with nerve decompression surgery through the lateral-rectus approach. The operative time, intraoperative bleeding, length of hospitalization, Gibbons nerve damage score and neurological recovery at the last follow-up were recorded. Results:In the 10 patients, the operative time was (112.0±21.5) min, intraoperative bleeding (215.0±91.3) mL, and length of hospitalization 7.0 (6.0, 8.5) d. Intraoperatively, sacral plexus nerve compression was found in 9 cases (6 cases of nerve compression and pulling due to fracture displacement, 3 cases of nerve entrapment due to soft tissue scar adhesion), and 1 case of nerve root avulsion injury. No other intraoperative complications occurred. The 10 patients were followed up for (9.2±2.3) months after surgery. At the last follow-up, the Gibbons score for the 10 patients improved from preoperative 3.0 (3.0, 3.3) points to 1.0 (1.0, 2.0) point, and their British Medical Research Council (BMRC) nerve injury grading was improved from the preoperative grade 0.0 (0.0, 1.3) to grade 3.5 (2.8, 4.0) (1 case of M5, 4 cases of M4, 4 cases of M3, and 1 case of M2).Conclusion:The lateral-rectus approach is effective and safe for exploration and decompression of the sacral plexus nerve in patients combined with sacral plexus nerve injury despite sacral fracture fixation.

Objective:To explore the clinical efficacy of operative treatment of geriatric pelvic fractures.Methods:A retrospective study was conducted to analyze the clinical data of 55 geriatric patients with pelvic fracture who had been operatively treated at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from January 2020 to October 2023. There were 13 males and 42 females with an age of 72.0 (68.0, 83.3) years. By the AO/OTA classification, there were 47 cases of type B and 8 cases of type C; by the classification for fragility fractures of pelvis, there were 5 cases of type Ⅱ, 44 cases of type Ⅲ, and 6 cases of type Ⅳ. The patients received operative treatment 4.0 (3.0, 6.3) days after injury. Of the 10 patients treated by open reduction and closed reduction, the posterior ring was fixated by a plate in 7 and by screws in 3, and the anterior ring was fixated by either a plate, an external fixator or a minimally invasive anterior pelvic ring internal fixator except in the 2 cases receiving no fixation. Of the other 45 patients treated by closed reduction and fixation, the posterior ring was all fixated by screws except in the 2 cases receiving no fixation, and the anterior ring was fixated by either screws, an external fixator or a minimally invasive anterior pelvic ring internal fixator except in the 10 cases receiving no fixation. The major peri-operative complications, quality of fracture reduction, mortality, and functional recovery of the pelvis at the last follow-up were recorded.Results:There were no major peri-operative complications. According to the Matta criteria, the quality of fracture reduction was excellent in 31, good in 14, fair in 8 and poor in 2 cases, giving a good to excellent rate of 81.8% (45/55). Fifty-four cases were followed up for (15.4±9.1) months and 1 case was lost to the follow-up. Four cases died within 1 year after operation, giving a mortality of 7.4% (4/54). The modified Majeed score at the last follow-up was 69 (54, 76) for the 46 cases who had been followed up for longer than 4 months; the functional recovery of the pelvis at the last follow-up was rated as excellent in 27 cases, as good in 8 cases and as fair in 11 cases, giving a good to excellent rate of 76.1% (35/46) according to the criteria proposed by the faculty of the writers. The internal fixation failed in 3 cases during the follow-up.Conclusion:For the geriatric pelvic fractures, operative treatment can lead to satisfactory clinical outcomes.

Objective:To investigate the clinical efficacy of three-connections and four-screwings technique in the treatment of high double column acetabular fractures through a single ilioinguinal approach.Methods:A retrospective study was conducted to analyze the data of 42 patients who had been treated for high double column acetabular fractures from June 2017 to June 2020 at Trauma Ward 2, Department of Orthopedics and Traumatology, The First Hospital of Traditional Chinese Medicine of Changde. There were 19 males and 23 females with an age of (42.7±25.6) years. 29 injuries were due to a traffic accident, 12 ones to fall from a height, and one to fall. The time from injury to operation was (4.5±2.1) days. All the patients were treated by the three-connections and four-screwings technique through a single ilioinguinal approach. Briefly, the anterior column was connected and secured to the main bone using 3 routes, and the posterior column was attached and fixated to the anterior column reset using 2 or 3 of the 4 screwings. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, hip function at the last follow-up and complications during the follow-up were recorded.Results:For this cohort, the operation time was (150.0±30.5) min, and intraoperative blood loss (300.0±50.0) mL. According to the Matta scale for postoperative acetabular fracture reduction, 34 cases were excellent, 6 cases good, and 2 cases acceptable, with an excellent and good rate of 95.2% (40/42). After operation one patient had fat liquefaction and wound exudation which responded to drainage and dressing change. The 42 patients were followed up for (15.0±3.4) months. All fractures healed after (11.0±2.0) months. By the modified Merle d'Aubigné & Postel scoring system, the hip function was evaluated at the last follow-up as excellent in 33 cases, as good in 6 cases, and as fair in 3 cases, yielding an excellent and good rate of 92.9% (39/42).Conclusions:In the treatment of high double column acetabular fractures, the three-connections and four-screwings technique through a single ilioinguinal approach can lead to fine reduction and rigid fixation by lag screw compression and neutralization plate protection. Consequently, early functional exercises can be performed to secure good therapeutic outcomes for the patients.

Closed reduction percutaneous screw fixation offers significant biological and biomechanical advantages and can be employed independently for the surgical treatment of pelvic acetabular fractures, as well as serving as a complementary method to open reduction internal fixation. The osseous fixation pathway (OFP) constitutes the anatomical foundation for the minimally invasive approach to pelvic and acetabular fracture management. The pelvis's OFP can be categorized into anterior, middle, and posterior parts. The anterior OFP encompasses both the superior pubic/anterior column and inferior pubic OFPs. The former is primarily utilized for addressing transverse and T-shaped acetabular fractures, as well as anterior column and superior pubic fractures. The latter is predominantly applied to inferior pubic fractures. The middle OFP includes the anterior inferior iliac spine to the posterior iliac crest (LC-II) OFP, the gluteus medius column OFP, and the iliac crest OFP. The LC-II OFP is primarily designated for pelvic crescent, iliac wing, and select high anterior column acetabular fractures. The gluteus medius column OFP is used for the treatment of some iliac fractures or acetabular fractures. And the iliac crest OFP is used for the treatment of simple iliac wing fractures or acetabular fractures involving the iliac crest. The posterior OFP includes the posterior column of the acetabulum OFP, sacroiliac OFP, and sacral OFP. The posterior column of the acetabulum OFP is used for the treatment of acetabular fractures involving the posterior column; the sacroiliac OFP is mainly utilized for a range of pelvic injuries, including pelvic rotational or vertical unstable pelvic injury, sacroiliac dislocation or fracture dislocation; open injury of the posterior ring of the pelvis with relatively mild contamination; elderly sacral (incomplete) fractures; residual gap at the end of sacral fracture after pubic symphysis and plate internal fixation; certain traumatic spinopelvic dissociation ; in combination with lumbopelvic fixation for the treatment of pelvic fractures with lumbosacral junction injury. Sacral OFP is advised for treating bilateral sacroiliac dislocation and certain crescent-like pelvic fractures; bilateral sacral fractures; sacral fractures involving Denis III zone, osteoporotic sacral incomplete fractures. The pursuit of minimally invasive treatment modalities for pelvic and acetabular fractures comes with challenges. A comprehensive understanding of OFP morphology and intraoperative imaging, coupled with a commitment to enhancing fracture reduction quality and surgical proficiency, is imperative for the precise management of such injuries.

ABSTRACT Open fractures are highly incident injuries closely related to the modern life, in which accidents caused by motor vehicles or other machines impart high energy to bone tissue. Individual morbidity is represented by the functional impairment resultant of infection, nonunion, or vicious healing. In terms of public health, there are huge costs involved with the treatment of these fractures, particularly with their complications. One of the critical issues in managing open fractures is the use of antibiotics (ATB), including decisions about which specific agents to administer, duration of use, and ideal timing of the first prophylactic dose. Although recent guidelines have recommended starting antibiotic prophylaxis as soon as possible, such a recommendation appears to stem from insufficient evidence. In light of this, we conducted a systematic review, including studies that addressed the impact of the time to first antibiotic and the risk of infectious outcomes. Fourteen studies were selected, of which only four found that the early initiation of treatment with antibiotics is able to prevent infection. All studies had important risks of bias. The results indicate that this question remains open, and further prospective and methodologically sound studies are necessary in order to guide practices and health policies related to this matter. Level of Evidence II; Therapeutic Studies Investigating the Results Level of Treatment.
RESUMO As fraturas expostas são lesões altamente incidentes, intimamente relacionadas à vida moderna, na qual os acidentes causados por veículos automotores ou outros aparatos transmitem alta energia ao tecido ósseo. A morbidade individual é representada pelo comprometimento funcional resultante de infecção, não-união ou cicatrização viciosa. Há enormes custos envolvidos no tratamento dessas fraturas em termos de saúde pública, principalmente quanto as complicações. Uma das questões críticas no tratamento de fraturas expostas é o uso de antibióticos, incluindo as decisões sobre quais agentes específicos devem ser administrados, a duração e o momento ideal para a primeira dose profilática. Embora as diretrizes recentes tenham recomendado o início da profilaxia antibiótica o mais rápido possível, essa recomendação parece se basear em evidências insuficientes. Em vista disso, realizamos uma revisão sistemática, incluindo estudos que abordaram o impacto do tempo até o primeiro antibiótico e o risco de resultados infecciosos. Foram selecionados 14 estudos, dos quais apenas quatro concluíram que o início precoce do tratamento com antibióticos é capaz de prevenir infecções. Todos os estudos tinham riscos importantes de viés. Os resultados indicam que essa questão permanece em aberto, sendo necessários mais estudos prospectivos e metodologicamente sólidos para orientar as práticas e políticas de saúde relacionadas a esse assunto.

ABSTRACT Objective To describe and analyze the aspects regarding the cost and length of stay for elderly patients with bone fractures in a tertiary reference hospital. Methods A cross-sectional retrospective study using data obtained from medical records between January and December 2020. For statistical analysis, exploratory analyses, Shapiro-Wilk test, χ2 test, and Spearman correlation were used. Results During the study period, 156 elderly patients (62.2% women) with bone fractures were treated. The main trauma mechanism was a fall from a standing height (76.9%). The most common type of fracture in this sample was a transtrochanteric fracture of the femur, accounting for 40.4% of cases. The mean length of stay was 5.25 days. The total cost varied between R$2,006.53 and R$106,912.74 (average of R$15,695.76) (updated values). The mean daily cost of hospitalization was R$4,478.64. A positive correlation was found between the length of stay and total cost. No significant difference in cost was observed between the two main types of treated fractures. Conclusion Fractures in the elderly are frequent, resulting in significant costs. The longer the hospital stay for treatment, the higher the total cost. No correlation was found between total cost and number of comorbidities, number of medications used, and the comparison between the treatment of transtrochanteric and femoral neck fractures.

ABSTRACT Introduction: The Judet and Letournel classification is the most widely used classification system for acetabular fractures. Some complex fractures couldn't be classified according to this classification. The main purpose of this study was to evaluate the reliability of the Letournel and Judet classification system for acetabular fractures. Material and methods: 10 acetabular fractures were analyzed among 17 orthopedic surgeons. The surgeons were asked to classify the fractures according to the Judet and Letournel classification. Their experience, the number of surgeries, and the incision type that the surgeon uses for the anterior part of the acetabulum were recorded. Results: The overall interobserver agreement for the Letournel classification was found to be poor, with a Kappa value of 0.287. The Kappa value for interobserver agreement was 0.224 for plain radiographs, 0.293 for 2D-CT, and 0.321 for 3D-CT scans. There was no significant difference between the incision types used by the surgeons. The highest reliability was determined among the surgeons who operate on 10-20 acetabular fractures per year, with a Kappa value of 0.309. Conclusion: This results revealed that the Judet and Letournel Judet classification is not sufficient to classify acetabular fractures because of unclassified fractures and the complex algorithm of the system. Level of Evidence III; Comparative Retrospective Study.
RESUMO Introdução: A classificação de Judet e Letournel é o sistema de classificação mais amplamente utilizado para fraturas acetabulares. Algumas fraturas complexas, porém, não puderam ser classificadas de acordo com esta classificação. O principal objetivo deste estudo foi avaliar a confiabilidade do sistema de classificação de Judet e Letournel para fraturas acetabulares. Material e métodos: Foram selecionadas aleatoriamente 10 fraturas acetabulares de um banco de dados. Participaram do estudo 17 cirurgiões ortopédicos. Foi solicitado aos cirurgiões que classificassem as fraturas de acordo com a classificação de Judet e Letournel. Suas experiências, o número de cirurgias e o tipo de incisão que o cirurgião utiliza para a parte anterior do acetábulo foram registrados. Resultados: A concordância interobservadores geral para a classificação de Judet e Letournel foi considerada fraca, com um valor de Kappa de 0,287. O valor de Kappa para a concordância interobservadores foi de 0,224 para radiografias simples, 0,293 para tomografias computadorizadas em 2D e 0,321 para tomografias computadorizadas em 3D. Não houve diferença significativa entre os tipos de incisão utilizados pelos cirurgiões. A maior confiabilidade foi determinada entre os cirurgiões que operam de 10 a 20 fraturas acetabulares por ano, com um valor de Kappa de 0,309. Conclusão: Os resultados revelaram que a classificação de Judet e Letournel não é suficiente para classificar fraturas acetabulares devido a fraturas não classificadas e ao algoritmo complexo do sistema.

Abstract Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment. In the upper limbs, this is very evident in the systematization of the reduction and percutaneous fixation of supracondylar fractures of the humerus and fractures of the forearm bones. In the lower limbs, the same occurs with diaphyseal fractures of the femur and tibia. However, there are gaps in the literature. The available published studies show low scientific evidence. Thus, it can be inferred that, even though the surgical approach is more present, the treatment of pediatric fractures should always be individualized and conducted according to the knowledge and experience of the professional physician, taking into account the presence of technological resources available for the care of the small patient. All possibilities, non-surgical and/or surgical, should be included, always instituting actions based on science and in agreement with the family's wishes.
Resumo Historicamente, as cirurgias no esqueleto imaturo eram reservadas às fraturas expostas ou articulares. Nos últimos anos, a melhora na qualidade e segurança das anestesias, novos equipamentos de imagem, implantes desenhados especialmente para fraturas pediátricas, associados à possibilidade de menor tempo de hospitalização e rápido retorno ao convívio social vêm demonstrando uma nova tendência de avaliar e tratar fraturas na criança. O objetivo deste artigo de atualização é responder às seguintes questões: (1) estamos realmente ficando mais cirúrgicos na abordagem das fraturas em crianças? (2) Caso isto seja verdadeiro, esta conduta cirúrgica está baseada em evidências científicas? De fato, nas últimas décadas, a literatura médica demonstra artigos que suportam melhor evolução das fraturas na criança com o tratamento cirúrgico. Nos membros superiores, isto fica muito evidente na sistematização da redução e fixação percutânea das fraturas supracondilianas do úmero e das fraturas de ossos do antebraço. Nos membros inferiores, o mesmo ocorre com fraturas diafisárias do fêmur e tíbia. No entanto, há lacunas na literatura. Os estudos publicados são geralmente com baixa evidência científica. Assim, pode-se deduzir que, mesmo sendo a abordagem cirúrgica mais presente, o tratamento de fraturas pediátricas deve ser sempre individualizado e conduzido de acordo com o conhecimento e experiência do médico profissional, levando em conta a presença de recursos tecnológicos disponíveis para o atendimento do pequeno paciente. Deve-se incluir todas as possibilidades, não cirúrgicas e/ou cirúrgicas, sempre instituindo ações baseadas na ciência e em concordância com os anseios da família.

Abstract Objective This study assessed differences between fully- and partially-threaded screws in the initial interfragmentary compression strength. Our hypothesis was that there would be an increased loss in initial compression strength with the partially-threaded screw. Methods A 45-degree oblique fracture line was created in artificial bone samples. The first group (FULL, n = 6) was fixed using a 3.5-mm fully-threaded lag screw, while the second group (PARTIAL, n = 6) used a 3.5-mm partially-threaded lag screw. Torsional stiffness for both rotational directions were evaluated. The groups were compared based on biomechanical parameters: angle-moment-stiffness, time-moment-stiffness, maximal torsional moment (failure load), and calibrated compression force based on pressure sensor measurement. Results After loss of one PARTIAL sample, no statistically significant differences in calibrated compression force measurement were observed between both groups: [median (interquartile range)] FULL: 112.6 (10.5) N versus PARTIAL: 106.9 (7.1) N, Mann-Whitney U-test: p = 0.8). In addition, after exclusion of 3 samples for mechanical testing (FULL n = 5, PARTIAL n = 4), no statistically significant differences were observed between FULL and PARTIAL constructs in angle-moment-stiffness, time-moment-stiffness, nor maximum torsional moment (failure load). Conclusion There is no apparent difference in the initial compression strength (compression force or construct stiffness or failure load) achieved using either fully-or partially-threaded screws in this biomechanical model in high-density artificial bone. Fully-threaded screws could, therefore, be more useful in diaphyseal fracture treatment. Further research on the impact in softer osteoporotic, or metaphyseal bone models, and to evaluate the clinical significance is required.
Resumo Objetivo Este estudo avaliou diferenças entre parafusos com rosca total ou parcial na resistência à compressão interfragmentar inicial. Nossa hipótese era de que haveria maior perda de resistência à compressão inicial com o parafuso de rosca parcial. Métodos Uma linha de fratura oblíqua de 45 graus foi criada em amostras de osso artificial. O primeiro grupo (TOTAL, n = 6) foi fixado com um parafuso de 3,5 mm de rosca total, enquanto o segundo grupo (PARCIAL, n = 6) usou um parafuso de 3,5 mm de rosca parcial. Avaliamos a rigidez à torção em ambas as direções de rotação. Os grupos foram comparados com base nos seguintes parâmetros biomecânicos: momento de rigidez-ângulo, momento de rigidez-tempo, momento de torção máxima (carga de falha) e força de compressão calibrada com base na medida do sensor de pressão. Resultados Depois da perda de uma amostra PARCIAL, não foram observadas diferenças estatisticamente significativas na força de compressão calibrada entre os 2 grupos [mediana (intervalo interquartil)]: TOTAL: 112,6 (10,5) N e PARCIAL: 106,9 (7,1) N, com p = 0,8 segundo o teste U de Mann-Whitney). Além disso, após a exclusão de 3 amostras para testes mecânicos (TOTAL, n = 5, PARCIAL, n = 4), não foram observadas diferenças estatisticamente significativas entre os construtos TOTAL e PARCIAL quanto ao momento de rigidez-ângulo, momento de rigidez-tempo ou momento de torção máxima (carga de falha). Conclusão Não há diferença aparente na força de compressão inicial (força de compressão ou rigidez do construto ou carga de falha) com o uso de parafusos de rosca total ou parcial neste modelo biomecânico em osso artificial de alta densidade. Parafusos de rosca total podem, portanto, ser mais úteis no tratamento de fraturas diafisárias. Mais pesquisas são necessárias sobre o impacto em modelos ósseos osteoporóticos ou metafisários de menor densidade e avaliação do significado clínico.

Abstract Objective To compare the use of cannulated screws and smooth Kirschner wires in terms of reducing the presence of exuberant callus and complications in pediatric displaced fractures of the lateral humeral condyle. Methods An analytical cross-sectional study of consecutive cases was conducted from May to October 2021 with 30 children with displaced external humeral condyle fractures. The functional results regarding pain and range of motion were stratified using the Dhillon grading system. Results A total of 19 patients underwent Kirschner wire fixation, and 11 underwent cannulated screw fixation. Closed fixation was performed in 14 cases (47%), and open fixation, in 16 (53%). Of the cases included, there was no loss to follow-up. Te sample was composed of 21 (70%) male patients, and the age ranged from 5 to 15 years, with a mean of 6.96 years. The most frequent cause of fracture was fall from height (50%), which was related to greater displacement on baseline radiographs. Complications that were not related to the reduction approach or the implant used were observed in 12 (40%) cases. Conclusion The present study shows no benefits in relation to the use of smooth pins or cannulated screws to reduce the presence of exuberant callus in the consolidation of the fracture. We see that the complications that arise are related to the severity of the injury, and benefits cannot be identified in the choice of one implant over another. We could see that the Weiss classification helps to define the behavior in favor of open or closed reduction without interfering in kindness of the smooth pin or the cannulated screw for fracture fixation.
Resumo Objetivo Comparar o uso de parafusos canulados e de fios de Kirschner lisos em termos da redução da presença de calo exuberante e de complicações em fraturas pediátricas deslocadas do côndilo lateral do úmero. Métodos Um estudo analítico transversal de casos consecutivos foi realizado de maio a outubro de 2021 com 30 crianças com fraturas deslocadas de côndilo umeral externo. Os resultados funcionais para dor e amplitude de movimento foram estratificados utilizando o sistema de classificação Dhillon. Resultados Ao todo, 19 pacientes foram submetidos à fixação de fio Kirschner, e 11 à fixação de parafusos canulados. A fixação realizada foi fechada em 14 casos (47%) e aberta em 16 (53%). Dos casos incluídos, não houve perda no acompanhamento. A amostra continha 21 (70%) pacientes do sexo masculino, e a idade variou de 5 a 15 anos, com média de 6,96 anos. A causa mais frequente de fratura foi queda de altura (50%), e esteve relacionada ao maior deslocamento nas radiografias da linha de base. Complicações que não estavam relacionadas à abordagem de redução ou ao implante utilizado foram observadas em 12 (40%) casos. Conclusão Este estudo não mostra benefícios em relação ao uso de pinos lisos ou de parafusos canulados para reduzir a presença de calo exuberante na consolidação da fratura. Vemos que as complicações que surgem estão relacionadas à gravidade da lesão, e não é possível identificar benefícios na escolha de um implante ou outro. Pudemos ver que a classificação de Weiss ajuda a definir o comportamento em favor da redução aberta ou fechada sem dar preferência ao pino liso ou ao parafuso canulado para a fixação da fratura.

Objective:To analyze the compliance with enhanced recovery after surgery (ERAS) protocol in geriatric patients with fresh fracture.Methods:A retrospective study was conducted on the data of the patients with fresh extremity fracture which had been included in the ERAS perioperative protocol database during May 2019 and January 2022 at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital. The patients ≥65 years were selected as a study group which was matched by a control group of the patients < 65 years in sex, fracture type and date frame of hospitalization at a ratio of 1∶1. The 2 groups were compared in the compliance with the 14 ERAS core perioperative elements.Results:The study group and the control group each included 66 patients who were matched in sex and fracture type. 62.1% (41/66) of the patients in the study group had combined diseases, significantly more than that [16.7% (11/66)] in the control group( P<0.001). Altogether, the compliance with the 14 ERAS core perioperative elements was 78.6 (71.4, 85.7) % in both groups, showing no significant difference between them ( P>0.05). Respectively, the compliance with the postoperative oral intake in the study group (80.3%, 53/66) was significantly lower than that in the control group (92.4%, 61/66) ( P<0.05); the compliance with the other 13 elements showed no statistically significant difference between the 2 groups ( P>0.05). Conclusion:The ERAS perioperative protocol can be carried out smoothly in geriatric patients with fresh fracture whose compliance may be comparable to that of the none-elderly patients.

Objective:To develop a deep learning model which can automatically and accurately detect osteoporotic vertebral compression fractures (OVCF) based on artificial intelligence.Methods:MRI images of 500 patients diagnosed with OVCF at The First People＇s Hospital of Guangzhou from January 2019 to October 2021 were collected retrospectively. There were 396 males and 204 females, with an age of (74.5±6.0) years. The T value of bone mineral density was -2.9±0.8. The fracture segments were L1 in 128 cases, L2 in 113 cases, L3 in 109 cases, L4 in 115 cases, and L5 in 108 cases. The multimodal layered converged network was used to train, test, and verify the robustness and generalization ability of a deep learning model based on MRI images of OVCF. The grad-cam was applied to visualize the results. The diagnostic value of the model for OVCF was assessed by comparing the diagnoses between the artificial intelligence model and 2 senior spinal surgeons on the MRI images of 30 OVCF patients randomized from the 500 ones.Results:Of the precise auxiliary diagnosis model for OVCF based on MRI images, the diagnostic accuracy was 96.7%, the sensitivity 93.5%, the specificity 88.9%, the positive predictive value 100.0%, and the negative predictive value 86.6%, all significantly higher than those of the 2 senior spinal surgeons (70.0%, 72.7%, 28.6%, 82.1%, and 28.6%) ( P<0.05). Conclusion:The present study has successfully established a deep learning model which can automatically and accurately diagnose OVCF based on MRI images, showing a high diagnostic efficiency than human spinal surgeons.

Objective:To evaluate the efficacy of arthroscopic minimally invasive reduction in the treatment of talus posterior process fractures.Methods:The clinical data were retrospectively studied of the 42 patients with talus posterior process fracture who had been admitted to Department of Orthopedics, The Fourth Hospital of Wuhan from January 2010 to June 2021. There were 25 males and 17 females, aged from 21 to 60 years (average, 40.5 years). They were assigned into 2 groups according to their different treatments. In the arthroscopic group of 15 cases, arthroscopic reduction and internal fixation (ARIF) were conducted via the posteromedial and posterolateral approaches; in the open reduction group of 27 cases, open reduction and internal fixation (ORIF) were conducted via the posteromedial para-Achilles approach. The 2 groups were compared in terms of operation time, blood loss, hospital stay, fracture clinical healing time, postoperative complications, and the American Society for Foot and Ankle Surgery (AOFAS) ankle-hindfoot score at one year postoperation.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P> 0.05). The arthroscopic group incurred significantly less blood loss [(32.0±11.5) mL], hospital stay [(5.3±1.8) d], and fracture clinical healing time [(4.6±1.0) months], and a significantly lower incidence of postoperative complications [20.0% (3/15)] than the open reduction group did [(80.0±15.2) mL, (8.4±2.4) d, (6.3±2.2) months, and 29.6% (8/27)], but significantly longer operation time [(74.0±8.9) min] than the open reduction group [(62.9±5.1) min] ( P<0.05). The AOFAS ankle-hindfoot scores at one year postoperation in both groups were higher than those before operation. The AOFAS ankle-hindfoot scores in the arthroscopic group [(83.0±13.0) points] were significantly higher than those in the open reduction group [(72.3±16.0) points] ( P<0.05). Conclusion:ARIF is a preferred minimally invasive treatment for talus posterior process fractures, because it leads to a smaller incision, less blood loss, shorter hospital stay, quicker clinical healing, a lower incidence of postoperative complications, and better functional improvement of the ankle and hindfoot than ORIF.

Adult atlantoaxial complex fractures, an acute injury which is rare in clinic, may lead to neurological damage or even death. Their current treatments can be conservative or surgical. The conservative treatment may involve collar bracket, Halo bracket, and sterno-occipital mandibular immobilizer (SOMI) while the surgical treatment mainly involves anterior cervical fixation and posterior cervical fixation. This review expounds on the current literature concerning the treatment of adult atlantoaxial complex fractures so as to provide reference for correct choice of treatment methods for this kind of fractures.
