“…In clinical setting there is a higher incidence of avulsion fractures at the fibular end of the ATFL (Broström, 1964(Broström, , 1966. However, biomechanical studies suggest the opposite, with the talar end of the ATFL being more vulnerable to avulsion fractures (St Pierre et al, 1983;Attarian, 1985). St Pierre et al (1983) studied the tensile strength to destruction in 36 ligaments.…”

Injuries to the lateral ligament complex of the ankle are common problems in acute care practice. We believe that a well-developed knowledge of the anatomy provides a foundation for understanding the basic mechanism of injury, diagnosis, and treatment, especially surgical treatment, of lateral collateral ankle ligament injury. To address this issue we performed this review with regard to the anatomy of the lateral collateral ankle ligaments.

“…It runs deep to the peroneal tendons which function as the dynamic stabilizers of the ankle. As the ankle is dorsiflexed, the CFL is tensioned, and the CFL works to stabilize the ankle joint in this position [19]. The PTFL originates on the lateral malleolus and inserts on the posterolateral aspect of the talus [8].…”

Purpose of review Ankle sprains, which account for 40% of sports injuries in the USA, can lead to chronic ankle instability. Chronic ankle instability can be classified as functional, mechanical, or a combination of both and is diagnosed using a combination of a physical exam, an MRI, and stress radiographs. This review focuses on different approaches to treatment, including non-operative and operative techniques, of chronic ankle instability, including reviewing traditional procedures as well as more novel and newer techniques. Recent findings Based on existing literature, non-operative treatment should always precede operative treatment of chronic ankle instability. If rehabilitation fails, Brostrom-Gould type ankle stabilization has been the preferred surgical option. Recent literature suggests that arthroscopic repair might reduce recovery time and improve outcomes in certain populations; however, there are higher rates of complication following these surgeries. In more high-risk populations, some literature reports that ligament repair with peroneus brevis transfer could be a more effective treatment option. Summary Currently, varying surgical techniques exist for the treatment of chronic ankle instability. While the more recently reported techniques show promise, it is important to note that there is little evidence showing they are more successful than traditional techniques. It is imperative that future studies focus on outcomes and complication rates of these newer procedures.

“…Investigators have measured the mechanical behavior of ankle ligaments from cadaveric specimens in various ankle positions and defined the roles of each ligament in stabilizing the ankle (1,7,27 jects who have a history of recurrent ankle sprains. Therefore, the purpose of this study was to compare the resistance to inversion obtained at the maximum passive inversion range of motion in the involved and uninvolved ankles of subjects with unilateral recurrent inversion sprains.…”

0ne of the most common injuries associated with physical activity is the inversion sprain of the lateral ligament5 of the ankle (l3,14,39). Reports have indicated that approximately 20-60% of individuals with this injury have some form of subsequent disability (12,18,39). Factors suggested to contribute to postsprain dysfunction include ligament laxity (20,25), proprioceptive deficiency (25,31), peroneal muscle weakness (SO), tibiofibular sprain (33), bony deformity (24), subtalar instability (6), and synovial hypertrophy (1 1 ) . Although a number of factors have been suggested, the primary mechanism underlying residual instability remains unclear (38).Functional instability was first described by Freeman et al (12) to classify patients with ongoing complaints of "giving-way" of the ankle. Occurring in approximately 40% of patients with inversion sprains (12), functional instability has been described as the most common and serious residual disability following ankle sprains (21) and has been reported to result in chronic complaints of pain and swelling, recurrent spl-ains (28,35), and degenerative joint changes (16). Inversion Sprains Although a number of mechanical and neuromuscular processes have been identified, the primary mechanisms underlying residual functional instability-of the ankle remain unclear. Understanding such mechanisms will help physical therapists identify where to focus treatment efforts, ultimately leading to more effective rehabilitation. In the present investigation, resistive toque at maximum ankle inversion was evaluated to determine if lateral ankle structures demonstrated mechanical laxity. Thirty subjects with a history of unilateral recurrent inversion sprains were tested bilaterally. A custom-made apparatus provided a stress to the lateral ankle in
