Introduction

Talus fractures are fractures that occur in the talus region, which is a structure situated in the ankle and the foot. The talus is crucial for mobility, and these fractures largely compromise the foot and the ankle from functioning, therefore leading to those affected having walking difficulties.¹ The talus is crucial in both movement and stability as it is responsible for ankle movement and joints such as the transverse tarsal and subtarsal joints. The transverse tarsal joint connects the midfoot region and the hindfoot. Therefore, the talus, which is situated in the hind foot, is important in ensuring proper foot function.² In the National Collegiate Athletic Association (NCAA), stress fractures in the foot and ankle are estimated to affect less than 1% of athletes, but this may be higher in reality as some injuries may not be adequately reported and monitored.³ The risk for talus fractures is fairly low. However, many sports possess a high likelihood of causing these fractures.

Talus fractures can have severe impacts on athletic performance, and the recovery time varies from athlete to athlete.⁴ Hence, it is important to understand how these injuries affect athletes and the extent to which those who are affected suffer as a result. This article is going to explore talus fractures and how they affect athletes by investigating the impact on performance as well as recovery time. Prevention strategies and successful case studies will also be evaluated.

Causes and risk factors in athletes

There are several reasons why athletes are more susceptible to talus fractures when compared to the general population. High-impact sports such as basketball are linked to an increased prevalence of talus fractures. In those who play basketball, people with a talocalcaneal coalition in which the talus and calcaneum bones are connected in an abnormal way are predisposed to developing talus fractures.⁵ Talar lesions also occur in basketball players, and this leads to cartilage near the joints being damaged.⁶ Football players and gymnasts are also susceptible to these types of fractures and injuries.⁷

Moreover, talus fractures can occur due to trauma such as falls and collisions, such as in skiing. Sudden twisting movements are also closely linked to the prevalence of talus fractures.⁸ Stress injuries typically affect the head region of the talus, and repeated stress injuries in this bone increase the likelihood of fractures.⁹ Additionally, pre-existing conditions such as tarsal or the aforementioned talocalcaneal coalitions lead to individuals being more susceptible to these fractures.¹⁰

Impact on athletic performance

Talus fractures affect athletes in various ways. In the immediate aftermath, athletes will find it difficult to bear weight, and this may last for up to three months depending on the severity of the fracture. Furthermore, pain and swelling can occur in the affected area for approximately two weeks following the fracture.¹¹ In the long term, athletes have demonstrated a decreased range of motion and lower strength. Stiffness in this region is also a long-term consequence that can lead to lower athletic performance.¹²

The psychological effects of these fractures should also not be underestimated. Athletes might be less confident following a period of inactivity, and they might be worried about the possibility of another fracture in the future. ⁽¹³⁾ These injuries lead to effects which are sport-specific in many cases. The ability to jump and pivot is decreased, and overall agility is compromised. As the athletes that are more susceptible to these injuries generally play high-impact sports, these effects can be devastating regarding the long-term outcomes of those affected. For example, jumping is highly necessary in basketball. ¹⁴

Diagnosis and treatment approaches

Fortunately, there are techniques available to diagnose and treat these injuries. In order to diagnose talus fractures, imaging techniques such as computed tomography (CT) scans, magnetic resonance imaging (MRI) scans, and X-ray imaging can be used. These techniques are useful in determining whether there is indeed an injury as well as the extent of the injury.¹⁵ Moreover, many options are available for treatment. Nonsurgical interventions such as immobilisation, in which a cast may be used, is utilised to limit the movement of the affected region.

This will lead to the talus healing over time as the joints recover.¹⁶ Surgical techniques such as using screws are commonly used to treat talus fractures. However, this prevents the ability to monitor the affected area using MRI. This technique, alongside plate insertion and bone grafts, in which bones are transplanted to the affected region, are useful in severe instances.² Avulsions, in which part of the bone is disconnected from the remainder of the bone, can be treated using nonsurgical interventions. More severe instances that affect the talar body as well as subtler joints may require surgical intervention.¹⁷

Recovery timeline and rehabilitation

Recovery typically follows a set timeline. The acute healing phase entails ensuring that the fracture does not become more severe and that it is essentially stabilised. The subacute phase, on the other hand, involves healing the fracture through the aforementioned treatment techniques.¹⁸ These healing phases are followed up by rehabilitation, in which patients use exercises and training to restore talus function as much as possible.¹³ The recovery timeline of athletes differs depending on the severity of the injury. However, when bone grafts are required, athletes can only return to activity after up to five months on average.¹⁹

This time can be lower if athletes do not require surgical intervention, in which case athletes may be fully recovered in two to three months.²⁰ Physical therapy for those affected focuses on improving muscle strength, alongside mobility and proprioception, i.e., when the body can detect movement, which is crucial for athletes.²¹ Athletes who do not require major surgical interventions gradually return to training following rehabilitation and might be able to play before two months in some cases.²²

Factors affecting recovery time

There is a wide array of factors that affect the recovery of athletes experiencing talus fractures. The severity of the fracture affects the time of recovery and determines the type of treatment needed. Surgical intervention leads to a typically longer recovery time compared to nonsurgical techniques.²³ Other factors, such as the age of injury and any pre-existing issues or medical conditions, also lead to a variable recovery time.¹⁹ The ability of those affected to comply with rehabilitation procedures also leads to recovery time differing between patients.²⁴

Prevention strategies

Several strategies can be implemented to prevent talus fractures. Initiatives such as effective strength and conditioning programmes, as well as appropriate footwear, are integral to reducing the risk of injury.²⁵ Ensuring that athletes are fully aware of the signs of stress injuries and fractures would also prevent overtraining and repetitive stress injuries, which are factors that might cause talus fractures.²⁶ Modifying training regimens, such as incorporating rest periods and focusing on reducing the risk of injury, is also an effective measure to prevent talus fractures from occurring. This involves reducing impact forces, which are known to result in these injuries.²⁷

Case studies and real-world examples

There are real-life examples of athletes that demonstrate the impact of talus fractures and the need for proper treatment and rehabilitation. For instance, treadmills are used to heal stress fractures and are a common rehabilitation strategy, which was used by Ryan Suter, an American ice hockey player. This is because treadmills allow a gradual return to sport whilst encouraging a routine.¹³ Following rehabilitation with treadmill activity, Ryan was able to return to ice hockey the following season after experiencing a talus fracture, contrary to some athletes who are unable to return to their respective sports.

It is worth emphasising that recovery and rehabilitation should be a gradual process and that athletes, including Ryan, are still suffering from the long-term consequences of talus fractures despite a patient recovery. Other athletes have returned after four months of suffering a talus fracture and have been relatively successful in the long term. Baseball is a high-impact sport despite not being a full-contact sport.²⁸

Summary

In summary, talus fractures are more common amongst athletes who play high-impact sports such as basketball and football. It arises due to trauma as a result of certain movements and repeated stress injuries. Although this can lead to a reduced range of motion and strength issues in the long term, significantly affecting performance, there are treatments available—surgical, and nonsurgical—which can lead to a full recovery depending on the severity of the fracture. Some athletes can recover and start competing again after a matter of months. However, it is highly important to have a gradual rehabilitation and return to training. A rushed recovery would only exacerbate the injury.

Having a full awareness of talus fractures is crucial to prevent them from happening. However, in the case when a fracture has occurred, an early diagnosis is essential to allow faster treatment before the injury becomes more severe. More advanced diagnostic techniques will allow better diagnosis and monitoring of those with talus fractures. A further emphasis on preventing injuries and structured regimens to minimise these risks will lead to fewer athletes suffering from talus fractures in the future. Furthermore, this will lead to better outcomes for athletes with talus fractures in the future.
