Review
Acute patellar dislocation (PD) is usually a problem of adolescents and young adults. In most cases, it is a sports-related injury. It is the result of an indirect force on the knee joint, which leads to valgus and external rotation of the tibia relative to the femur. PD is unlikely to occur on a knee with normal patellofemoral joint (PFJ) anatomy. Acute PD consists of an acute injury of the ligamentous medial patellar stabilizers in the background of factors predisposing to patellar instability. These factors are classified into three groups. The first group refers to the integrity of the ligamentous medial patellar restraints, particularly, the medial patellofemoral ligament (MPFL). The second group refers to an abnormal PFJ anatomy, which renders the patella inherently unstable inside the trochlea. The third group refers to the overall axial and torsional profile of the lower limb and to systemic factors, such as ligament laxity and neuromuscular coordination of movement. PD at a younger age is associated with an increased number and severity of patellar instability predisposing factors and lower stress to dislocate the patella. Acute primary PD is usually treated conservatively, while surgical treatment is reserved for recurrent PD. The aim of treatment is to restore the stability and function of the PFJ and to reduce the risk of patellar redislocation. Surgical procedures to treat patellar instability are classified into non-anatomic and anatomic procedures. Non-anatomic procedures are extensor mechanism realignment techniques that aim to center the patella into the trochlear groove. Anatomic procedures aim to restore the PFJ anatomy (ruptured ligaments, osteochondral fractures), which has been severed after the first incident of PD. Anatomic procedures, especially MPFL reconstruction, are more effective in preventing recurrent PD, compared with non-anatomic techniques. Theoretically, all factors that affect PFJ stability should be evaluated and, if possible, addressed. This is practically impossible. Considering that the MPFL ruptures in almost all PDs, MPFL reconstruction is the primary procedure, which is currently selected by most surgeons as a first-line treatment for patients with recurrent PD. Restoration of the axial and torsional alignment of the lower limbs is also increasingly implemented by surgeons. Non-anatomic surgical techniques, such as tibial-tuberosity osteotomy, are used as an adjunct to anatomic procedures. In the presence of multiple PFJ instability factors, acute MPFL reconstruction may be the treatment of choice for acute primary PD as well. Skeletal immaturity of the patient precludes osseous procedures to avoid premature physis closure and subsequent limb deformity. Unfortunately, restoration of the patient's previous activity level or participation in more strenuous sports is questionable and not easy to predict. In the case of competitive athletes, PD may prevent participation in elite levels of sports.

Review
Normal bone remodeling depends of a balance between bone forming cells, osteoblasts and bone resorbing cells, the osteoclasts. In chronic arthritides and some inflammatory and autoimmune diseases such as rheumatoid arthritis, there is a great constellation of cytokines produced by pannus that impair bone formation and stimulate bone resorption by inducing osteoclast differentiation and inhibiting osteoblast maturation. Patients with chronic inflammation have multiple causes that lead to low bone mineral density, osteoporosis and a high risk of fracture including circulating cytokines, impaired mobility, chronic administration of glucocorticoids, low vitamin D levels and post-menopausal status in women, among others. Biologic agents and other therapeutic measures to reach prompt remission might ameliorate these deleterious effects. In many cases, bone acting agents need to be added to conventional treatment to reduce the risk of fractures and to preserve articular integrity and independency for daily living activities. A limited number of studies related to fractures in chronic arthritides were published, and future investigation is needed to determine the risk of fractures and the protective effects of different treatments to reduce this risk.

Review
OBJECTIVE
Denosumab, an antiresorptive agent, has shown results in improving bone mineral density and reducing fractures in postmenopausal women. While bisphosphonates are commonly used as initial therapy for osteoporosis, some studies suggest that denosumab could be an alternative initial treatment for high-risk patients, particularly the elderly population. This narrative literature review aimed to assess the use of denosumab in elderly individuals with osteoporosis, excluding its oncology applications.
METHOD
Multiple online databases including Scopus, PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), and PEDro were searched for relevant English-language trials.
RESULTS
Between about hundred identified, the review selected 21 articles full-meeting the inclusion criteria. These papers all reporting that Denosumab demonstrated significant efficacy in reducing vertebral and nonvertebral fractures in postmenopausal and senile osteoporosis.
CONCLUSION
Even if limited evidence exists regarding its long-term effectiveness in elderly patients, nevertheless denosumab may be considered a first-line treatment for high-risk elderly patients with senile osteoporosis, particularly for those unable to take bisphosphonates. It has shown superior outcomes in improving bone density and reducing fracture risk, even in frail elderly individuals. Long-term use of denosumab has been reported as safe and effective, enhancing treatment compliance and outcomes.

Non-traumatic fractures due to seizures are an overlooked diagnostic group. It is well known that patients with generalized tonic-clonic seizures have an increased trauma risk. However, the cause of fracture is rarely due to the violent forces of muscle contractions. Usually, the primary patient examination focuses on the aetiology of the seizure, which sometimes delays the diagnosis of fractures. This is a case report of a 19-year-old woman who sustained three compression fractures of the thoracic spine due to a generalized tonic-clonic seizure, and a discussion of the diagnostic challenges in such a rare case.
