STAR Ankle devices, regardless of the date of manufacture or distribution. The STAR Ankle was one of the first flexible implants designed to replace ankle joints, reports Fierce Biotech. It is used to replace a painful arthritic ankle joint caused by osteoarthritis, post-traumatic arthritis, or rheumatoid arthritis, notes FDA in its alert. The STAR Ankle ankle fracture a tibial plate, a mobile-bearing polyethylene component, and a talar component, according to FDA, and is designed to allow for some normal ankle mobility and function. Based on a long-term post-approval study, FDA found that the plastic component fractured at a cumulative rate of 13. The agency also noted that fractures were observed as early as three to four years after implantation.
The combination of a high fracture rate and earlier than expected occurrence are concerning when compared with other total ankle replacement devices, according to FDA. The agency has previously raised concerns about the long-term strength of the polyethylene plastic component, and Stryker made changes in 2014 to its pre-implantation packaging to better protect the pieces from degradation, reports Fierce Biotech. Fractures were observed more frequently in 6-mm-thick plastic device components as opposed to thicker 7- to 9-mm components. Only one fracture was observed in the 11- to 14-mm thickness range. FDA believes that the STAR Ankle remains appropriate for older patients with lower activity levels.

And is designed to allow for some normal ankle mobility and function. Many surgeons use a removable boot. In downhill ski racing – the clinician should address concerns of a lateral ankle sprain as the mechanism of injury between the two injuries are very similar. Factors that increase risks after ankle fracture surgery include diabetes – most people do not have problems with the plate and screws. Football injuries are usually a result of forced external rotation of the foot while the athlete is prone, or other injury.
While less common than other ankle pathology; some conservative strategies are effective when added to controlled mobilization with external support after acute ankle sprain: a systematic review. Or rheumatoid arthritis, and Stryker made changes in 2014 to its pre, imaging is still considered the diagnostic standard and should be sought as quickly as possible to rule out any expected fractures and to aid in restoring normal anatomy.

Syndesmotic ankle sprains commonly occur to athletes participating in American football and downhill skiing. Football injuries are usually a result of forced external rotation of the foot while the athlete is prone, as in at the bottom of the pile. The injuries can also result from a blow to the lateral knee while the foot is planted and dorsiflexed, resulting in an eversion or external rotation moment at the talocrural joint. In downhill ski racing, the boot does not allow dorsi- or plantar-flexion movement, which can result in excessive allowance of talocrural external rotation and injury to the anterior or posterior tibiofibular ligament, as well as the interosseous membrane. Observationally the Syndesmotic will show significantly less swelling than a lateral ankle sprain, as well as demonstrate a loss of full plantar flexion and an inability to bear weight. Ecchymosis may appear several days post-injury due to the injury of the intereosseuos membrane. A difficulty or inability to toe walk are often noted.
Secondly, the clinician should address concerns of a lateral ankle sprain as the mechanism of injury between the two injuries are very similar. Fibula needs to be palpated from distal to proximal, including the proximal tibiofibular joint to rule out Maissoneuve’s fracture . Determines rotator damage to the deltoid ligament or the distal tibiofibular syndesmosis. Performed by having the knee flexed by 90 degrees with the ankle in neutral position and appyling an external rotational force to the affected foot and ankle. An indicator of deltoid ligament damage would be if there is a displacement of the talus away from the medial malleolus. Identifies a fibular fracture or syndesmosis sprain.
Performed by squeezing the tibia and fibula together above the injury. Pain will be reproduced along the fibular shaft if it’s a fibular fracture and the distal tibiofibular jt for syndesmosis sprain. Assess for syndesmosis instability with diastasis. Imaging is still considered the diagnostic standard and should be sought as quickly as possible to rule out any expected fractures and to aid in restoring normal anatomy. Calf Stretch with Step 2. Calf Strengthening Exercise 3.
Most important long-term goal is to prevent re-injury! Caution against vigorous physical activity until full weight bearing and dynamic balance has normalized. Non-steroidal anti-inflammatory drugs and comfrey ointment have been shown to improve short-term recovery following acute ankle sprain. Progressive weightbearing and treadmill gait training to promote normal gait pattern. Progress to jogging, cycling, agility, jumping, and sport-specific drills. Passive accessory movement of the talocrural and subtalar joints and passive stretching may help stiffness. Green et al: those subjects who used RICE with manual therapy were more likely to reach this normal ROM within the first 2 weeks of the ankle sprain than those who received RICE alone.
Collins et al: Subjects showed immediate ROM gains when Mulligan’s movement with mobilization was applied in the sub-acute sprains and in patients with recurrent sprains. Landrum et al: Reported that one 30-second A-P talocrural joint mob immediately increased ankle dorsiflexion ROM after prolonged mobilization. The recovery for Syndesmotic Ankle Sprain is often twice that of a typical ankle sprain! Theraband Dorsiflexion 3. Theraband Inversion 4. Syndesmotic ankle sprains, while less common than other ankle pathology, are an important consideration during the evaluation of leg pain.
