Filter by:The optimal treatment of ankle fractures with involvement of the posterior malleolus remains a subject of debate. Despite a large amount of literature on the role of the posterior malleolus in a so-called trimalleolar fracture, there are no clear guidelines for its treatment. Its size is the leading indication whether fixation of the fragment is necessary or not. Most orthopedic surgeons consider a posterior malleolar fracture fragment larger than 25% to 33% an indication for fixation. Interestingly, after careful evaluation of the available literature, there does not seem to be hard evidence for these numbers. It is generally accepted that restoration of a normal anatomic mortise and normal tibiotalar contact area are key elements for a good functional outcome. Inadequate reduction of the posterior fragment may alter the tibiotalar contact area and the joint biomechanics with altered stresses in parts of the joint, leading to the development of osteoarthritis and worse functional outcome. Traditionally, reduction of these larger fragments is indirectly, followed by percutaneous screw fixation in anterior-posterior direction. Disadvantages are that it is hard to achieve an anatomical reduction, and that fixation of smaller fragments is very difficult. Recently, a direct exposure of the posterior tibia via a posterolateral approach in prone position, followed by open reduction and fixation with screws in posterior-anterior direction or antiglide plate is advocated by several authors. This approach allows perfect visualization of the fracture, articular anatomical reduction, and strong fixation. Another advantage is that even small posterior fragments can be addressed. Several case series are published, which describe minimal major wound complications, good functional outcomes, and minimal need for reoperation. Since 2 years, in our institution we perform an open, anatomical reduction and fixation of all medium-sized posterior fragments via this approach. Although not thoroughly investigated yet, it seems to lead to better clinical outcomes than described in the literature and our retrospective cohort study.
Background: An anatomical reconstruction of ankle congruity is an important prerequisite in the operative treatment of acute ankle fractures. But, despite an anatomic reduction, patients suffer from residual problems like chronic pain, stiffness, persistent swelling and instability after these fractures. There is growing evidence, that this poor outcome is related to the concomitant traumatic intraarticular pathology. Therefore, supplementary ankle arthroscopy has been proposed in acute ankle fractures as it is a valuable tool to confirm the anatomic reposition and to further identify and manage associated intraarticular injuries. The arthroscopic treatment of these pathologies might result in a better outcome after complex ankle fractures. Nevertheless, until now, the vast majority of ankle fractures are managed by open procedures only. Still, indications for arthroscopically assisted open reduction and internal fixation (AORIF) are not clearly stated, and the effectiveness of AORIF compared with open reduction and internal fixation (ORIF) has not yet been determined for complex ankle fractures. In this context, only a prospective randomized study can sufficiently answer these open questions. Therefore, the investigators plan a randomized controlled trial intended to report the short-, midterm- and long-term follow-up of patients who underwent operative treatment of acute ankle fractures - with and without ankle arthroscopy. Methods/Study design: The investigators will perform a randomized controlled trial evaluating the effect of AORIF compared to ORIF with a sample size of 40 patients per group. The investigators include patients with an acute ankle fracture after written informed consent. Primary outcome of the investigators' study is the difference of the AOFAS score (American Orthopedic Foot and Ankle Society) between the intervention (AORIF) and comparison (ORIF) group after a follow-up of 2 years. Several secondary outcome parameters will be assessed as well. Statistical analysis will be performed using a two-sided Student`s t-test. Discussion: Until today, there are only two randomized controlled trials evaluating the effect of open reduction and internal fixation (ORIF) compared to arthroscopically assisted open reduction and internal fixation (AORIF). Both studies only included patients with isolated fractures of the distal fibula at the level of the syndesmosis. These are the most simple fractures that are regularly treated operatively. Both studies documented a high incidence of intraarticular disorders in the AORIF group, but only one could show significant better results in the AORIF group. Moreover, several other studies could consistently demonstrate that the intraarticular damage is even more pronounced the more complex the fracture is. Consequently, a more distinctive effect of arthroscopy in complex fractures involving two malleoli or more has to be assumed when compared to these simple fractures.
This study investigates, in a randomized setting, the use of intermittent in-cast pneumatic foot-compression (IPC) in the preoperative treatment of malleolar fractures. This is to investigate whether the IPC has any effect on preventing swelling of the ankle, and thereby preventing delay of surgery due to swelling. The investigators will include patients with malleolar fractures that require surgery in two groups, IPC and bandage or bandage only, and measure the time from diagnosis-to-surgery.
Unstable ankle fractures are commonly treated operatively. After operative reduction and fixation of the fractures, there are varying rehabilitation regimes that include non-weightbearing for 6 weeks with active range of motion exercise in a removal cast or brace, or early protected weightbearing in a rigid cast. Several papers reported that early weightbearing may decrease ankle stiffness, muscle and bone atrophy, and aids in early return to activities. However, early weightbearing may have the risk of displacement of the fixed fractures. Rehabilitation after operative treatment of an ankle fracture is still not clear. We hypothesized that the ankle function assessed on 12 months after operation of an ankle fracture with early weightbearing is not inferior to non-weightbearing but is superior to non-weightbearing with respect to time to return to normal daily life and time to full weightbearing.
The primary objective of the investigators randomized controlled trial is to determine if early protected weightbearing and ankle range of motion after surgical treatment (open reduction internal fixation - ORIF) for ankle fractures improves the rate of return to work and functional outcome compared to postoperative ankle immobilization in a non-weightbearing cast.
The purpose of this study is to evaluate of functional tests and clinical findings with APOS System treatment in patient after bi-trimalleolar fracture of ankle. These functional changes will be evaluated AOFS, FAOS, SF36 and WOMAC scores, walking laboratory GAITRite and clinical examination.
