Ankle injuries in athletes: A review of the literature

Ankle injuries are commonplace in the athletic population, with lateral ligament sprains accounting for the majority of them. The medial ligament complex, the distal tibiofibular syndesmosis as well as any of the bones that constitute the ankle joint can also be injured. Typical mechanisms of injury include inversion-plantarflexion and external rotation on a supinated, dorsiflexed or pronated foot. Lesions of the ankle present with similar symptoms of pain, swelling and tenderness. Therefore, a thorough history and physical examination must be obtained to make the correct diagnosis. This is especially critical for athletes as certain injuries can lead to termination of their career if not treated accurately on time. Imaging may be useful in some cases to confirm or rule out differential diagnoses. Most injuries can be managed conservatively using the Protection, Rest, Ice, Compression and Elevation protocol followed by a comprehensive rehabilitation programme. Surgery is reserved for grade III ligament tears that are refractory to initial non-operative treatment and displaced fractures that are unlikely to unite without surgical intervention. The objective of this review is to discuss the common ankle injuries encountered in the athletic population and the approaches to their diagnosis and management.     

Update on acute ankle sprains

Ankle sprains are a common problem seen by primary care physicians, especially among teenagers and young adults. Most ankle sprains are inversion injuries to the lateral ankle ligaments, although high sprains representing damage to the tibiofibular syndesmosis are becoming increasingly recognized. Physicians should apply the Ottawa ankle rules to determine whether radiography is needed. According to the Ottawa criteria, radiography is indicated if there is pain in the malleolar or midfoot zone, and either bone tenderness over an area of potential fracture (i.e., lateral malleolus, medial malleolus, base of fifth metatarsal, or navicular bone) or an inability to bear weight for four steps immediately after the injury and in the emergency department or physician's office. Patients with ankle sprain should use cryotherapy for the first three to seven days to reduce pain and improve recovery time. Patients should wear a lace-up ankle support or an air stirrup brace combined with an elastic compression wrap to reduce swelling and pain, speed recovery, and protect the injured ligaments as they become more mobile. Early mobilization speeds healing and reduces pain more effectively than prolonged rest. Pain control options for patients with ankle sprain include nonsteroidal anti-inflammatory drugs, acetaminophen, and mild opioids. Because a previous ankle sprain is the greatest risk factor for an acute ankle sprain, recovering patients should be counseled on prevention strategies. Ankle braces and supports, ankle taping, a focused neuromuscular training program, and regular sport-specific warm-up exercises can protect against ankle injuries, and should be considered for patients returning to sports or other high-risk activities.

Ankle injuries in athletes.

Ankle injuries are the most frequent cause of physician evaluation in a sports-oriented environment. The lateral ligaments are most commonly injured. With a detailed history, physical and radiographic examination to avoid missing underlying pathology, the primary care physician can diagnose and treat the majority of ankle injuries. Occasionally, stress radiographs, arthograms, or magnetic resonance imaging (MRI) is needed. The vast majority of ankle sprains can be treated with adhesive tape strapping or semirigid orthotics and nonsteroidal anti-inflammatory medication followed by rehabilitation. Key points of rehabilitation are control of pain and swelling acutely with nonsteroidal anti-inflammatories and RICE (rest, ice, compression, and elevation), then restoring normal range of motion, strengthening muscle groups, and retraining proprioception of the ankle joint.     

The effectiveness of balance training programs on reducing the incidence of ankle sprains in adolescent athletes

Ankle sprains are one of the most common sport-related injuries treated by rehabilitation professionals. These injuries often result in lost participation and can lead to subsequent injury episodes. Therefore, it is important to determine appropriate means of preventing these injuries. There has recently been an increase in the popularity of balance training programs for the prevention of knee anterior cruciate ligament (ACL) injury, with some thought that starting these programs in younger athletes may be most beneficial. However, there is the potential that these types of training programs may also be beneficial for decreasing the risk of other lower extremity injuries, including ankle sprains in the adolescent athlete.     

Braces and splints for musculoskeletal conditions

Braces and splints can be useful for acute injuries, chronic conditions, and the prevention of injury. There is good evidence to support the use of some braces and splints; others are used because of subjective reports from patients, relatively low cost, and few adverse effects, despite limited data on their effectiveness. The unloader (valgus) knee brace is recommended for pain reduction in patients with osteoarthritis of the medial compartment of the knee. Use of the patellar brace for patellofemoral pain syndrome is neither recommended nor discouraged because good evidence for its effectiveness is lacking. A knee immobilizer may be used for a limited number of acute traumatic knee injuries. Functional ankle braces are recommended rather than immobilization for the treatment of acute ankle sprains, and semirigid ankle braces decrease the risk of future ankle sprains in patients with a history of ankle sprain. A neutral wrist splint worn full-time improves symptoms of carpal tunnel syndrome. Close follow-up after bracing or splinting is essential to ensure proper fit and use.     

Diagnostik und Therapie der chronischen Sprunggelenkinstabilität

Ankle sprains are the most common musculoskeletal injuries accounting for approximately 15–25% of injuries treated in the medical practice. Although most of these ligamentous ankle injuries can be successfully treated with physical rehabilitation and non-operative treatment, 20–40% of patients complain of chronic instability and subsequent disability. Many of these patients can be successfully treated by late repair or reconstruction of the lateral ligaments. However, in spite of surgery and extensive physical rehabilitation, many patients suffer from persisting disability including symptomatic instability. New investigation methods such as imaging techniques and arthroscopy have shown that different types of ankle instability exist. Chronic pain, feeling of instability of the ankle during daily and sports activities and recurrent sprains are the main indications for surgical repair or reconstruction of ligaments. Techniques that restore the anatomy have shown better results than non-anatomic procedures as they do not alter the kinematics or the mechanics of the ankle joint complex. Therefore, non-anatomic tenodesis procedures should no longer be performed despite some positive results.     

Lateral and syndesmotic ankle sprain injuries: a narrative literature review

Objective

The purpose of this article is to review the literature that discusses normal anatomy and biomechanics of the foot and ankle, mechanisms that may result in a lateral ankle sprain or syndesmotic sprain, and assessment and diagnostic procedures, and to present a treatment algorithm based on normal ligament healing principles.

Methods

Literature was searched for years 2000 to 2010 in PubMed and CINAHL. Key search terms were ankle sprain$, ankle injury and ankle injuries, inversion injury, proprioception, rehabilitation, physical therapy, anterior talofibular ligament, syndesmosis, syndesmotic injury, and ligament healing.

Discussion

Most ankle sprains respond favorably to nonsurgical treatment, such as those offered by physical therapists, doctors of chiropractic, and rehabilitation specialists. A comprehensive history and examination aid in diagnosing the severity and type of ankle sprain. Based on the diagnosis and an understanding of ligament healing properties, a progressive treatment regimen can be developed. During the acute inflammatory phase, the goal of care is to reduce inflammation and pain and to protect the ligament from further injury. During the reparative and remodeling phase, the goal is to progress the rehabilitation appropriately to facilitate healing and restore the mechanical strength and proprioception. Radiographic imaging techniques may need to be used to rule out fractures, complete ligament tears, or instability of the ankle mortise. A period of immobilization and ambulating with crutches in a nonweightbearing gait may be necessary to allow for proper ligament healing before commencing a more active treatment approach. Surgery should be considered in the case of grade 3 syndesmotic sprain injuries or those ankle sprains that are recalcitrant to conservative care.

Conclusion

An accurate diagnosis and prompt treatment can minimize an athlete's time lost from sport and prevent future reinjury. Most ankle sprains can be successfully managed using a nonsurgical approach.     

The use of Bioptron light (polarized,polychromatic, non-coherent) therapy for the treatment of acute ankle sprains

Purpose The purpose of this study was to investigate the efficacy of Bioptron light therapy for the treatment of acute ankle sprains. Method A parallel group, single-blind, controlled study was carried out in patients with grade II acute ankle sprains. Patients were randomly allocated into two treatment groups (n?=?25 for each). Both groups received cryotherapy, and the test group also received Bioptron light therapy. All treatments were performed daily for 5 d. Evaluations included self-reported pain via a visual analogue scale, degree of ankle edema, and ankle range of motion via goniometry carried out before the treatment and at the end of the treatment. Results The test group showed the largest magnitude of improvement for all evaluations at treatment five, and the between-group differences observed were statistically significant (p?Conclusions These data provide preliminary evidence of the efficacy of Bioptron light therapy supplemented with cryotherapy for the treatment of acute ankle sprains; however, larger studies are required to confirm these results.

• Implications for Rehabilitation

• Ankle sprains are common acute injuries among professional and recreational sports players but also among people in general.

• Cryotherapy is the first-standard treatment of acute ankle sprains.

• Phototherapy such as Bioptron light has been recommended supplement to cryotherapy to reduce the symptoms of ankle sprains.

• The results of the present trial showed that using BIOPTRON LIGHT and cryotherapy the rehabilitation period of acute ankle sprains can be reduced.

     

Syndesmosis injuries of the ankle

Ankle syndesmosis injuries are relatively frequent in sports, especially skiing, ice hockey, and soccer, accounting for 1 %–18 % of all ankle sprains. The evolution is unpredictable: When missed, repeated episodes of ankle instability may predispose to early degenerative changes, and frank osteoarthritis may ensue. Diagnosis is clinical and radiological, but arthroscopy may provide a definitive response, allowing one to address secondary injuries to bone and cartilage. Obvious diastasis needs to be reduced and fixed operatively, whereas less severe injuries are controversial. Nonoperative treatment may be beneficial, but it entails long rehabilitation. In professional athletes, more aggressive surgical treatment is warranted.     

Home-based physical therapy intervention with adherence-enhancing strategies versus clinic-based management for patients with ankle sprains

BACKGROUND AND PURPOSE: To some extent, favorable treatment outcomes for physical therapy intervention programs depend on patients attending their clinic appointments and adhering to the program requirements. Previous studies have found less-than-optimal levels of clinic attendance, and a viable option might be physical therapy intervention programs with a large component of home treatment. This study investigated the effects of a standard physical therapy intervention program--delivered primarily at either the clinic or home--on ankle function, rehabilitation adherence, and motivation in patients with ankle sprains. SUBJECTS: Forty-seven people with acute ankle sprains who were about to start a course of physical therapy intervention participated in the study. METHODS: Using a prospective design, subjects were randomly assigned to either a clinic intervention group or a home intervention group. Ankle function and motivation were measured before and after rehabilitation, and adherence to the clinic- and home-based programs was measured throughout the study. RESULTS: The groups had similar scores for post-treatment ankle function, adherence, and motivation. The home intervention group had a significantly higher percentage of attendance at clinic appointments and better physical therapy intervention program completion rate. DISCUSSION AND CONCLUSION: Home-based physical therapy intervention appears to be a viable option for patients with sprained ankles.     

History of ankle sprain as a risk factor of future lateral ankle sprain in athletes

Despite the attention and focus lateral ankle sprains receive in athletic training practice and research, they remain the most common injury in many sports. Whereas the functional limitations and time loss from lateral ankle sprains are apparent, consistently reducing their incidence is less certain. One important step in preventing lateral ankle sprains is identifying their risk factors. Although previous literature summaries suggest that specific risk factors are inconclusive in predicting lateral ankle sprains, recent literature investigating the predictors of ankle sprains should be included as evidence. Determining the primary risk factors for lateral ankle sprains may lead to good prevention programs, which in turn may decrease time lost because of injury.     

Prise en charge des entorses externes de cheville : étude clinique préliminaire sur l’efficacité du dispositif Myolux™

Ankle sprains are the most common injury of the musculoskeletal system and are associated with significant societal and economic impacts. It has been proven that classical therapeutic strategies may not be effective in preventing recurrent injuries: the recurrence rates reported in the literature can reach 73%. In order to provide an effective rehabilitation solution, a destabilizing orthosis was developed. This device is equipped with a mechanical articulator reproducing the subtalar mechanics and placed under the heel. In this paper, we present the main results of a preliminary clinical study conducted between 2004 and 2007. All subjects included in this study were treated with the abovementioned orthosis during 10 rehabilitation sessions of 30 minutes each. Data show a relatively low recurrence rate of 12% for the overall population. Moreover, it's of primary importance to note that this satisfactory ratio is largely reduced (3% of recurrence rate) for the 29 patients who performed one training session per month after the 10th initial rehabilitation sessions. Hence, the destabilizing orthosis appears to be an effective solution to prevent recurrent ankle sprains. However, joint protection requires long-term and regular training sessions. This result has motivated the development of a similar device allowing patients to perform training sessions at home. Finally, data obtained in this study are promising awaiting the final results of the comparative, multicentric and independent clinical trials currently managed by the Hospices Civils de Lyon.

Syndesmotic ankle sprain

Ankle sprain injuries are the most common type of joint sprain. The prevalence of ankle joint sprains accounts for 21% of joint injuries in the body. Although somewhat rare, high-ankle or syndesmotic ankle sprains occur in up to 15% of ankle trauma. This article will present the pathomechanics of the high-ankle or syndesmotic sprain.     

Tibiofibular syndesmosis and ossification. Case report: sequelae of ankle sprain in an adolescent football player

Heterotopic ossification development within the interosseous membrane of the ankle is an uncommon occurrence after routine ankle sprains. We present a case of a high school football player who sustained a syndesmosis ankle sprain. After 4 weeks, he continued to have pain, swelling, and range of motion restriction despite being treated with cryotherapy, NSAIDs, supportive taping, and progressive rehabilitation. The radiographs revealed a heterotopic ossification within the interosseous membrane of the distal extremity. The patient was initially treated conservatively and went on to have surgical excision with an excellent result. Symptomatic patients will require definitive surgery even without frank synostosis.

MR imaging of ankle inversion injuries

Ankle inversions are common in the general population and in athletes. Multiple concurrent injuries are a common result of an ankle-inversion injury. Syndesmosis injury, lateral ankle ligament tears, peroneal retinaculum or tendon injury, osteochondral lesion, or fracture may occur. Chronic pain or instability may result from one or more of these injuries. MR imaging provides superior soft tissue resolution, high sensitivity for occult fractures, and the ability to image the articular cartilage and ankle ligaments directly. This article discusses the MR imaging evaluation of acute and chronic ankle inversion injuries.
