Monteggia-like lesions encompass a wide spectrum of fractures of the forearm and elbow associated with dislocations, subluxations and ligamentous lesions.Many attempts have been made to classify these injuries, not only to understand their pathology but also to develop optimal treatments.Unfortunately, although some of these classifications are complete, they are either complex, not immediately usable, or not exhaustive. An orthopedic surgeon who aims to rapidly treat this kind of injury needs a visual classification, and knowledge of the best surgical approach.Monteggia like lesions do not allow for mistakes during surgery, as even a minor error could be prove detrimental to performing and completing all surgical steps.In this paper, based on our extensive experience in treating these rare lesions, we suggest a practical guide to the best surgical approach for various types of Monteggia like lesions.Some technical tips and pitfalls are also described.
This procedure is easy, effective, economic and safe. It allows the harvesting of a significant number of ASCs that are ready for one-step bony regenerative surgical procedures.
The inverse relationship between proximal femoral fracture incidence and hip osteoarthritis remains controversial. However, femoral neck fractures rarely occur in patients with hip osteoarthritis, suggesting a protective effect of osteoarthritis. We sought to determine if the severity of osteoarthritis influenced fracture type. We examined the radiographs of 190 consecutive patients treated at our institution after hip trauma. They were divided into three groups according to the outcome of the trauma: femoral neck fracture; trochanteric fracture; and no fracture. We then analysed the severity of osteoarthritis within these groups.
No relationship between the grade of hip osteoarthritis and the presence of a proximal femoral fracture was found. However, the grade of osteoarthritis was related both to the outcome of the trauma (p<0.0001) and to the location of the fracture (p<0.0001). Patients with osteoarthritis of the hip had a three-fold increased likelihood of trochanteric fracture compared to femoral neck fracture. Osteoarthritis does not protect against proximal femoral fractures, but strongly affects the location of the fracture in the proximal femur, increasing the possibility of a trochanteric location.
In irreparable radial head fractures, especially if primary stabilizers of the elbow are damaged, the prosthetic replacement prevents instability and stiffness. Concerns have arisen over the use of bipolar press-fit prostheses due to the frequent finding of osteolysis and the risk of instability if compared to monopolar implants. Our aim was to assess midterm clinical and radiological outcomes of bipolar implants and the influence of osteolysis on proximal pain. Seventeen patients with irreparable fractures of the radial head, treated in acute with the same prosthetic model (rHEAD recon SBI/Stryker) between January 2015 and December 2018, were enrolled. Clinical assessment was performed using MEPS and DASH scores; a radiographic study was done to identify heterotopic ossifications and periprosthetic osteolysis. Outcomes at the last follow-up, according to MEPS, were excellent in 10 cases, good in 5 and fair in 2; none of the patients had severe pain or instability. In 3 cases, it was necessary to remove the implant, mainly because of early loosening. Radiological findings of osteolysis were detected in 9 cases, but no statistical correlation was found with MEPS and proximal pain. The use of bipolar implants is reliable if an accurate repair of ligament tears is performed and provides a good stability. Nevertheless, the risk of early aseptic loosening in uncemented implants is not negligible, and the follow-up of the patient must be strict. Late osteolysis does not seem to have clinical relevance, but further prospective studies are necessary to clarify this topic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
