“…For femoral valgus osteotomy, the authors used step-cut osteotomy [19] fixed with a plate and screws in four cases of type I or IV osteogenesis imperfecta because of reasonable bone stock available to carry this implant. As found in a case of bicycle accident (Case 1-R3), this implant carries a high risk of peri-implant fracture.…”

Femoral neck fracture (FNF) is not common in osteogenesis imperfecta patients but may result in serious complications if not properly treated in due time. We present three types of FNF in osteogenesis imperfecta and their characteristics, treatment methods and outcomes. Cases of FNF followed for more than 2 years were selected from the osteogenesis imperfecta database. Medical records and radiographs were reviewed to obtain demographic information and to determine ambulatory status, mode of injury, location of the fracture line, presence of preexisting implants, treatment methods and complications. Outcomes were evaluated according to the radiographic results and ambulatory function. The study investigated 15 FNFs in 10 patients including 1 Sillence type I, 1 type III and 8 type IV. They were either community or household ambulators. The mean age at fracture was 11.7 years. The fractures were followed for an average of 6.3 years. Six fractures were attributed to accidental injuries and nine without noticeable trauma. The fracture pattern was categorized into undisplaced (n = 3), angulated-stable (n = 7) or displaced-unstable (n = 5) types. Five fractures were fixed in-situ using screws or Kirschner wires. Other five fractures were treated by closed reduction and screw fixation and the remaining five fractures were managed by femoral valgus osteotomy. Bony union was achieved, and prefracture ambulatory status was restored in all cases. A high index of suspicion is required in the diagnosis of undisplaced or angulatedstable fractures. Treatment is usually challenging, but a judicious approach considering the fracture pattern and patient characteristics result in successful outcomes. The angulated-stable pattern of fracture is unique in osteogenesis imperfecta patients and requires special attention.

“…2 patients had previous proximal femoral osteotomy. 7 2 patients had a surgical history: 1 triple Chiari osteotomy 8 and 1 screw treatment of hip osteochondritis. There was one intraoperative complication (partial sciatic motor palsy) in the patient with a screw treatment of hip osteochondritis in childhood.…”

“…• The mean WOMAC total score was moderate: 38.1 ± 12.1 /100 (range, 7.3-52.1)). The pain component was 8.6 ± 3.4 /20 (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13), and the physical function component 27.9 ± 8.9 /68 (6-37). Stiffness was more severe: 2.9 ± 1.3 /8 (1-5).…”

To determine the survival of slotted acetabular augmentation in adult dysplasia, we reviewed all cases operated on between 2002 and 2020 with clinical and radiological assessment and a 2.63 year minimum of follow-up. Twenty-three patients were included, with 91% of Crowe 1 hip dysplasia. Seven patients underwent THA at a mean 6.0 ± 3.5 years; 15 retained SAA without THA at a mean 9.5 years' follow-up; 1 was lost to follow-up. There was a significant improvement in PMA and HHS scores, with decreased pain. WOMAC and SF12 quality-of-life scores were moderate due to frequent pain. The patients with preoperative osteoarthritis showed little progression at seven years 'follow-up. We concluded SAA is a corrective treatment for residual hip dysplasia. Its goal is to normalize joint loading by increasing the contact area and improving the lever arm of the hip. Its postponed onset of osteoarthritis and reduced pain, thereby allowing to postpone THA.
