1/1/2024 0 Comments Spiral fracture fibula![]() The following are described as subsequent events that result in a Maisonneuve fracture: The Maisonneuve fracture generally follows a specific pattern of injury. Pathophysiology Fracture of the lateral malleolus seen on X-ray scan (left ankle) ![]() This leaves the ankle joint in a state of chronic pronation, characterised by a protrusion of the medial malleolus into the subcutaneous tissue. ![]() If a Maisonneuve fracture is left untreated, instability of the tibiotalar joint and deltoid ligament can cause a valgus deformity of the ankle. A long-term effect of this is painful ankle osteoarthritis due to the direct contact between the tibia and talus. Īs the syndesmotic ligaments are responsible for stabilising the ankle mortise and tibiotalar joint, disruption to this syndesmosis can cause a reduction of the space between the distal tibia, fibula, and talus. Damage to the deltoid ligament or interosseous membrane can cause haemorrhaging around the surrounding tissues, resulting in a localised oedema. Pain may also be felt around the medial and lateral aspects of the ankle, and more rarely around the superior (or proximal) tibiofibular joint. Additionally, there is a reduced range of motion of the foot and an inability to weight-bear due to ankle pain. More specifically, as a pronation-external rotation injury, pain during external rotation of the ankle joint is expected. Signs and symptoms Fracture of the medial malleolus seen on X-ray scan (left ankle)Ĭommon symptoms of a Maisonneuve fracture are pain, swelling, tenderness, and bruising around the ankle joint and inferior (or distal) tibiofibular joint. In some cases, motor vehicle accidents can also result in a Maisonneuve fracture. Engaging in high-intensity sports or falling over can increase the risk of tearing the deltoid ligament or cause an avulsion fracture of the medial malleolus from external rotation of the foot. Cause įorceful, external rotation of the ankle joint is the main cause of a Maisonneuve fracture. The fracture is named after the surgeon Jules Germain François Maisonneuve. The Maisonneuve fracture is similar to the Galeazzi fracture in the sense that there is an important ligamentous disruption in association with the fracture. It is also classified as a Type C ankle fracture according to the Danis-Weber classification system. Due to this, the Maisonneuve fracture is described as a pronation- external rotation injury according to the Lauge-Hansen classification system. The Maisonneuve fracture is typically a result of excessive, external rotative force being applied to the deltoid and syndesmotic ligaments. This type of injury can be difficult to detect. There is an associated fracture of the medial malleolus or rupture of the deep deltoid ligament of the ankle. The Maisonneuve fracture is a spiral fracture of the proximal third of the fibula associated with a tear of the distal tibiofibular syndesmosis and the interosseous membrane.

1/1/2024 0 Comments Comfrey medicinal uses![]() For the first time, also a fast-acting effect of the ointment (1 h) was witnessed. Both the AUC of the reported back pain at rest, the AUC of the pressure algometry in the trigger point as well as the global assessment of the efficacy by the patients and the investigators showed a clinically relevant effect in reducing acute back pain. Also, in all secondary parameters, the superiority of the verum treatment compared with placebo was significant (each p < 0.001). The pain intensity on active standardised movement decreased on average (median) approximately 95.2 % in the comfrey extract group (104.8–12.7 mm (mean VAS sum)) and 37.8 % in the placebo group (100.0–56.5 mm (mean VAS sum) p < 0.001). The results showed a significant treatment difference between comfrey root extract and placebo regarding the primary variables. Secondary objectives were back pain at rest, pressure algometry, global assessment of efficacy by the patient and the investigator, intake of analgesic medication and functional impairment measured using the Oswestry Disability Index. ![]() Patients performed standardised, muscle group-specific tests to assess the pain intensity on VAS. The primary efficacy variable was the area under the curve (AUC) of the visual analogue scale (VAS) on active standardised movement values at first to fourth visit. The trial included four visits and was performed at the Deutsche Sporthochschule in Cologne and three additional ambulatory centres for orthopaedics and sports medicine. They were treated three times a day, 4 g per application. Total 120 patients with acute upper or lower back pain used either a verum cream containing comfrey root fluid extract (1:2, 35.0 g, extraction solvent ethanol 60 % (v/v), less than 0.35 ppm of pyrrolizidine alkaloids) or a corresponding placebo. Comfrey root as a herbal ingredient can contribute in the same way, as it is also known for its anti-inflammatory properties.Ī double-blind, placebo-controlled, multi-centre, randomised clinical trial with parallel group design was conducted over a period of 5 days. This approach has been intensively used and has proved to be efficacious in the management of symptoms, thus reducing pain, facilitating rehabilitation and achieving earlier recovery. The treatment strategy has recently also adopted a direct anti-inflammatory topical approach, mostly with chemical non-steroidal anti-inflammatory drugs (NSAIDs). ESCOP states that comfrey root has also been used for tendinitis syndrome, knee joint injuries, non-active gonarthrosis, insect bites, mastitis, fractures and skin inflammation, although published scientific evidence does not yet adequately support these indications.īack pain, especially of the upper and lower back, is a widespread condition impairing quality of life and functional movement in a large number of individuals. The monograph mentions strains, contusions and distortions, osteoarthritis (OA), epicondylitis, tendovaginitis and periarthritis as therapeutic indications substantiated by clinical trials. positively for the external use in bruises, strains and sprains and acknowledged its actions as anti-inflammatory, antimitotic and promotion of callus formation.įurther, a European Scientific Cooperative on Phytotherapy Monograph (ESCOP) is available for comfrey root. ![]() The German Commission E has assessed Symphyti radix (comfrey root) deriving from Symphytum officinale L. Allantoin and rosmarinic acid are probably of central importance for its pharmacodynamic effects. The key activity-determining constituents of comfrey root extracts and its molecular mechanisms of action have not been completely elucidated. A recent text book chapter gives detailed information on botanical aspects and harvesting of the plant. Native Americans recognised the healing powers and included comfrey root in their therapeutic armamentarium. It also naturalised in Northern America, where it rapidly spread. Native in Europe, the plant has an impressive record of medicinal use. Comfrey root has been used as a traditional medicinal plant for the treatment of painful muscle and joint complaints for centuries. ![]() The increased use of these programs is a byproduct of a continued tension between plan benefit design, the expansion of manufacturer copay program support, and the growth of spending. Though these programs employ different approaches, both forms of copay adjustment programs seek to exhaust manufacturer copay assistance while preventing these dollars from counting toward a commercially insured patient’s deductible and maximum out-of-pocket limit as they otherwise would have. To learn how Avalere can help your organization respond to-or shape-the evolving copay adjustment program landscape, connect with us.In recent years, payers and pharmacy benefit managers (PBMs) have increasingly used copay adjustment programs (i.e., copay accumulator and maximizer programs) to limit plan sponsor exposure to specialty drug costs. With hands-on policy experience from the payer, manufacturer, and third-party vendor perspectives, Avalere helps clients understand the evolving landscape of patient support and affordability, model the impacts of these policy changes, and identify solutions accounting for financial exposure while maximizing appropriate patient access. As stakeholders react to the developments of this court ruling, manufacturers, foundations, payers, and advocacy groups must also consider the role that other policy changes-such as Medicare Part D benefit redesign-play in patient support strategies. This ruling is the latest market and policy update in the evolving landscape of patient access and affordability support initiatives. To date, 19 states, the District of Columbia, and Puerto Rico have enacted copay accumulator bans, and Congress is currently considering the HELP Copays Act, which would prohibit copay accumulator use in individual, small group, and employer-sponsored health plans. This ruling could also ramp up state and federal legislation to restrict the use of copay accumulators. ![]() However, if plans respond with modified benefit structures, manufacturers may see an influx of additional patients seeking financial assistance.Īdditionally, questions remain as to how HHS will respond to this ruling, including whether they provide further interpretation of the definition of cost-sharing via future rulemaking (e.g., the 2025 proposed NBPP) or if they will file an appeal or motion to stay within 60 days.
