RESUMO

OBJECTIVES: To describe the surgical treatment of fractures that involves the hallux interphalangeal joint, current indications and management options. METHODS: we performed a literature review of relevant clinical studies in multiple databases, including PubMed, MedLine and Scopus, from January 1989 to October 2020. RESULTS: There is consensus for surgical treatment of intra-articular fractures with a deviation greater than 2 mm, metadiaphyseal fractures with malrotation and/or malangulation, open fractures and unstable fractures. CONCLUSION: The use of more rigid implants allow alignment maintenance during healing process and lower risk of reduction loss. Valgus deformity and interphalangeal joint osteoarthritis are possible complications that must be avoided. Level of Evidence III, Systematic review of Level III studies.

RESUMO

Rotator cuff tears (RCT) is a multifactorial disease with genetic factors contributing for the disease etiology. We hypothesized that genetic variants in genes involved in extracellular matrix (ECM) homeostasis may alter susceptibility to RCT. We evaluated 20 polymorphisms of genes involved in ECM homeostasis in 211 cases of full-thickness tears of the supraspinatus (Nfemales = 130; Nmales = 81) and 567 age-matched controls (Nfemales = 317; Nmales = 250). Multivariate logistic regressions were carried out with age, gender, genetic ancestry (based on the analysis of 61 biallelic short insertion/deletion polymorphisms), and common co-morbidities (diabetes, dyslipidemia, and smoking habits) as covariates. We observed that carriers of the rare allele of both studied variants of TGFB1, as well as their G/A (rs1800470/rs1800469) haplotype, were less susceptible to RCT (p < 0.05). In contrast, carriers of the G allele of MMP9 rs17576 (p = 0.014) or G/G haplotype (rs17576/rs17577; p < 0.001) had an increased risk for tendon tears. The presence of the T allele of MMP2 rs2285053 (p = 0.033), the T allele of MMP3 rs679620 (p = 0.024), and the TT-genotype of TIMP2 rs2277698 (p = 0.01) was associated with susceptibility to tears, especially in females. In males, the A allele of COL5A1 rs3196378 (p = 0.032) and the G allele of TGFBR1 rs1590 (p = 0.039) were independent risk factors for RCT. The C/T COL5A1 (rs3196378/rs11103544) haplotype was associated with a reduced risk of tears in males (p = 0.03). In conclusion, we identified the genetic variants associated with RCT susceptibility, thereby reinforcing the role of genes involved in the structure and homeostasis of the ECM of tendons in disease development. © 2019 Orthopaedic Research Society.

RESUMO

OBJECTIVE: To use magnetic resonance imaging to assess the prevalence of foot and ankle ligament injuries and fractures associated with ankle sprain and not diagnosed by x-ray. METHODS: We included 180 consecutive patients with a history of ankle sprain, assessed at a primary care service in a 12-month period. Magnetic resonance imaging findings were recorded and described. RESULTS: Approximately 92% of patients had some type of injury shown on the magnetic resonance imaging. We found 379 ligament injuries, 9 osteochondral injuries, 19 tendinous injuries and 51 fractures. Only 14 magnetic resonance imaging tests (7.8%) did not show any sort of injury. We observed a positive relation between injuries of the lateral complex, syndesmosis and medial ligaments. However, there was a negative correlation between ankle ligament injuries and midfoot injuries. CONCLUSION: There was a high rate of injuries secondary to ankle sprains. We found correlation between lateral ligament injuries and syndesmosis and deltoid injuries. We did not observe a relation between deltoid and syndesmosis injuries or between lateral ligamentous and subtalar injuries. Similarly, no relation was found between ankle and midfoot injuries.

RESUMO Objetivo Avaliar na ressonância magnética a prevalência das diferentes lesões ligamentares do tornozelo e do pé, bem como de fraturas não diagnosticáveis radiograficamente, em pacientes com queixa de entorse do tornozelo. Métodos Foram incluídos no estudo 180 pacientes consecutivos, com história de entorse do tornozelo, atendidos em um serviço de Atenção Primária no período de 12 meses. Os achados dos exames de ressonância magnética foram catalogados e descritos. Resultados Aproximadamente 92% dos pacientes apresentaram algum tipo de lesão na ressonância. Dentre as injúrias observadas, estavam 379 lesões ligamentares, 9 lesões osteocondrais, 19 lesões tendíneas e 51 fraturas. Apenas 14 ressonâncias magnéticas (7,8%) não mostraram qualquer tipo de lesão. Observamos relação positiva entre lesões do complexo lateral, sindesmose e medial. No entanto, houve correlação negativa entre lesões ligamentares do tornozelo e aquelas do mediopé. Conclusão Foi alta a ocorrência de lesões secundárias à entorse. Apontamos correlação entre as lesões ligamentares laterais com as sindesmodais e do deltoide. Não notamos relação entre as lesões do deltoide e da sindesmose, e nem entre as ligamentares laterais e a subtlalar. Também não foram observadas relações entre as lesões do tornozelo e as do mediopé.

RESUMO

OBJECTIVE: To compare analgesia and opioid consumption for patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. METHODS: The medical records of patients undergoing unilateral total hip arthroplasty between January 1st, 2017 and March 31, 2018 were reviewed, and 238 patients were included in the study. The primary outcome was postoperative opioid consumption in the first 24 postoperative hours. Secondary outcomes were intraoperative, post anesthesia care unit, and 48-hour opioid consumption, postoperative pain Visual Analog Scale scores, and post-anesthesia care unit length of stay. Primary and secondary endpoint data were compared between patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. RESULTS: For the patients who received quadratus lumborum block, the 24-hour total oral morphine equivalent (milligram) requirements were lower (53.82mg±37.41), compared to the patients who did not receive quadratus lumborum block (77.59mL±58.42), with p=0.0011. Opioid requirements were consistently lower for the patients who received quadratus lumborum block at each additional assessment time point up to 48 hours. Pain Visual Analog Scale scores were lower up to 12 hours after surgery for the patients who received a posterior quadratus lumborum block, and the post-anesthesia care unit length of stay was shorter for the patients who received quadratus lumborum block. CONCLUSION: Preoperative posterior quadratus lumborum block for primary total hip arthroplasty is associated with decreased opioid requirements up to 48 hours, decreased Visual Analog Scale pain scores up to 12 hours, and shorter post-anesthesia care unit length of stay. Level of evidence: III.

RESUMO

Frozen shoulder is a condition of loss of active and passive motion as result of inflammatory contracture and fibrosis of the joint capsule. We hypothesize that genetic variants in genes involved in these processes such as genes that play a role in extracellular matrix homeostasis (collagens, glycoproteins, genes involved in TGFß signaling, and metalloproteinases and its inhibitors) may contribute to the susceptibility to frozen shoulder. We evaluated eighteen SNPs of genes involved in extracellular matrix homeostasis in 186 cases (Nfemales = 114; Nmales = 72) of frozen shoulder and 600 age-matched controls (Nfemales = 308; Nmales = 292). Multivariate logistic regressions were carried out with age, gender, genetic ancestry, and common comorbidities as covariates. Carriers of the C allele of MMP13 rs2252070 and G/G MMP9 (rs17576 A>G/rs17577 G>A) haplotype may have an increased risk of frozen shoulder (p = 0.002, OR = 1.64, 95%CI = 1.20-2.26, and p = 0.046, OR = 1.40, 95%CI = 1.01-1.95, respectively), especially in females (p = 0.005, OR = 1.91, 95%CI = 1.22-2.99, and p = 0.046, OR = 1.59, 95%CI = 1.01-2.51, respectively). In females, the G allele of MMP9 rs17576 tended to contribute to the susceptibility to the studied disease (p = 0.05, OR = 1.51, 95%CI = 0.97-2.33). In contrast, the presence of the C allele of TGFB1 rs1800470 seems to be associated with a reduced risk (p = 0.04, OR = 0.47, 95%CI = 0.23-0.96) while the GG-genotype of TGFBR1 rs1590 was associated with increased risk (p = 0.027, OR = 4.11, 95%CI = 1.17-14.38) to frozen shoulder development in males. Thus, we identified genetic variants that were independent risk factors that can aid in the risk assessment of frozen shoulder reinforcing the involvement of MMP and TGFß signaling in disease development. © 2019 Orthopaedic Research Society.

RESUMO

INTRODUCTION: Calf augmentation is a procedure to enhance leg contour, therefore, providing better aesthetic aspect. Patient satisfaction is extremely high, and reported complications following this procedure are rare. CASE REPORT: The aim of this study is to report an as yet described complication related to calf implants: Prosthesis disruption in a 60-year-old female patient who fell downstairs and presented a closed bicondylar tibial plateau fracture on the right knee (Schatzker V). CONCLUSION: We believe this case report can alert orthopaedic surgeons to carefully evaluate leg images in traumatized extremities and look for calf augmentation implants, especially in unconscious patients.

RESUMO Objetivo Comparar a analgesia e o uso de opioides em pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e pacientes que não receberam o bloqueio do quadrado lombar. Métodos Revisamos os prontuários de pacientes submetidos à artroplastia total do quadril unilateral entre 1º de janeiro de 2017 e 31 de março de 2018, e 238 pacientes foram incluídos no estudo. O desfecho primário foi o consumo de opioides no pós-operatório nas primeiras 24 horas. Os desfechos secundários foram consumo de opioide no intraoperatório, na sala de recuperação pós-anestésica e nas primeiras 48 horas, escores de Escala Visual Analógica de dor pós-operatória, e tempo de permanência na recuperação pós-anestésica. Os desfechos primário e secundários foram comparados entre os pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e aqueles que não receberam o bloqueio do quadrado lombar. Resultados Para o grupo que recebeu o bloqueio, as doses totais de morfina por via oral em 24 horas foram menores (53,82mg±37,41) em comparação ao grupo sem bloqueio (77,59mg±58,42), com p=0,0011. A utilização de opioides foi consistentemente menor para o grupo que recebeu o bloqueio em cada tempo adicional de avaliação até 48 horas. Os escores da Escala Visual Analógica até 12 horas após a cirurgia para os pacientes que receberam o bloqueio do quadrado lombar posterior e o tempo de permanência na sala de recuperação pós-anestésica foram menores para o grupo que recebeu o bloqueio. Conclusão O bloqueio anestésico do quadrado lombar posterior para artroplastia total do quadril primária está associado à diminuição do uso de opioides nas primeiras 48 horas, diminuição do escore de dor da Escala Visual Analógica em até 12 horas, e menor tempo de permanência na sala de recuperação pós-anestésica.

RESUMO

Surgical management of lower extremity malunions and acute fractures in the setting of lower extremity deformities presents a unique challenge for orthopaedic surgeons. The objective of this study was to evaluate the outcomes of using the clamshell osteotomy in patients with acute fractures involving a malunion or deformity. A retrospective review of the cases performed by various orthopaedic traumatologists at 4 different trauma centers was performed to identify cases using the clamshell osteotomy from January 2012 to January 2016. Nine clamshell osteotomy cases were identified, 4 presenting fractures in the setting of previous malunions. All osteotomies healed within 15 months (average 6.8 ± 4.4 SD). In this multicenter case series, we demonstrate that using clamshell osteotomies can result in excellent outcomes for permitting intramedullary nailing of acute fractures in patients with lower extremity deformity.
