Case: A 6-year-old boy with a Renshaw type 4 sacral agenesis presented paraplegia and rigid, "Buddha-like" lower-limb contractures, including severe knee pterygia, which made crawling and sitting difficult. Staged surgical treatment involved bilateral knee disarticulation, soft tissue surgery, and bifocal femoral osteotomies for lower-limb reorientation. At 18 months postoperatively and after prosthetic fitting, the patient can stand and take steps with assistance. Conclusion:This effective surgical strategy achieves standing in a troublesome orthopaedic congenital condition. The intervention should be tailored to specific orthopaedic disorders and the wishes of patients and families, aiming to improve function. Sacral agenesis (SA) is a rare congenital malformation of the sacrococcygeal bone 1 that encompasses a wide spectrum of malformations of the caudal region of the spine. When associated with gastrointestinal or urogenital malformations it is referred to as caudal regression syndrome (CRS) 2 . Common orthopaedic abnormalities associated with SA are kyphoscoliosis, spinopelvic instability, and, in more severe cases, lower-extremity paraplegia with rigid flexion-abduction hip contractures, knee pterygia, and foot deformities 3 . This rigid, "Buddha-like" lower-limb position causes great functional impairment that not only prevents walking and standing but also inhibits comfortable sitting. If left untreated, as the child grows, wider chairs would be needed to accommodate the position and over time this would impede access through doorways and mobility even at home.The estimated incidence of SA is between 1 and 5 cases per 100,000 births 1 . The main risk factor found is maternal diabetes, which increases the risk of SA 20-fold 1 . Other related risk factors are folic acid deficit 4 , multiple pregnancies, smoking 1 , and retinoic acid intake 5 .

Introduction: Hip fractures affecting older people are at a higher risk of complications during the SARS-CoV-2 pandemic. The aim of this study is to provide data about proximal femoral fractures management and early outcomes during COVID-19 pandemic compared to the same period in 2019. Material and Methods: Retrospective and comparative study performed in two different periods were analyzed: from March 15, 2020, to April 30, 2020 (the first six weeks of Spain´s current confinement) and the same period in 2019. Data regarding demographics (age and sex, housing), type of fracture, surgical performance, early outcomes (at 30 days), and at 1-year follow-up were collected. A total of 146 patients were evaluated, 89 in 2019 and 57 in 2020. Results: Despite the drop ∼35.6% in hip fractures during SARS-CoV-2 period, distribution (age ( P = 0.985), sex ( P = 0.43), housing ( P = 0.61), type of fracture ( P = 0.41)) and Charlson comorbidity index ( P = 0.12) were similar to a 2019 period. Surgical performance did not worsen in spite of the tough situation and the use of personal protective equipment, improving in some radiological variables (tip-to-apex and calcar reduction). In terms of postoperative outcomes, although there is a tendency to a short-term mortality increase (from 3.4% to 5.2%, P = 0.22), there were no differences at 1-year follow-up (20.2% in 2019 and 20.4% in 2020, P=0.587). In the same line, although in both groups the patients lost functionality at 1 year, there were no significant differences ( P = 0.42). Conclusion: Even in challenging times, protocols and adequate organization ensure proper outcomes, reaching satisfying clinical and surgical outcomes during the COVID-19 pandemic, despite an increasing trend in short term mortality not seen at 1-year follow-up.
