Changes of Various Structures After Lisfranc Injury Compared to Healthy Individuals.

Overview

The effect of muscular strength deficits on postural control after Lisfranc injury has been explained in relation to stance duration and strength. However, the relationship between protective sole sensation and changes in ankle proprioception, balance, ankle mobility and Achilles tendon structural properties has been shown in previous studies. The aim of our study was to determine the possible changes in protective sole sensation, ankle proprioception, balance and functional capacity after Lisfranc injury and to analyse the relationship between these variables.

'Lisfranc injury' refers to an injury in which one or more metatarsals are displaced. Lisfranc injury covers a wide network of injuries. It includes various types, including a low-energy sports injury or a high-energy lesion, as well as a purely connective tissue injury. 20% of Lisfranc injuries are undiagnosed or diagnosed late. Early and accurate diagnosis of injuries is a basic requirement for appropriate treatment and prevention of secondary problems that may arise in the long term . Fracture-dislocation in the tarsometatarsal junction of the foot is treated with anatomical reduction, internal fixation or primary arthrodesis. However, many individuals have poor functional outcomes . Anatomical repositioning and excellent postoperative radiographic findings may not result in high patient satisfaction. As a result, no matter what type of treatment is used after Lisfranc injury, it should be supported by a good rehabilitation protocol. As a result of our research in the literature, the investigators encountered studies that performed gait analysis, muscle strength and plantar pressure measurements after Lisfranc injury. However, no study has been encountered examining parameters such as sole sense, proprioception, and balance after injury of the foot, which is the only limb in contact with the ground. After determining these values, revising the rehabilitation protocols specifically for the evaluation parameters will reduce the morbidity rate after injury and accelerate functional recovery. Rehabilitation protocols that emphasize the use of exercises to improve joint range of motion, muscle strength, neuromuscular coordination, and gait mechanics after foot and ankle injuries have been found to improve function . There is also evidence that the plantar flexor muscles of these patients are weakened after injury. There are also groups of patients who complain of instability when walking barefoot or on uneven ground after foot or ankle injuries. In a different study examining the dynamic plantar pressure distribution, force capacity and postural control change after Lisfranc injury, it was found that atrophy occurred after long-term immobilization in both the injured extremity and the contralateral extremity. Altered postural control after injury was manifested by a significant decrease in unilateral stance time. Adequate rehabilitation following anatomical open reduction after Lisfranc injury is very important for clinical outcome. A detailed evaluation is required to determine adequate rehabilitation. Considering these studies, evaluating balance will be important for patients with Lisfranc injuries.In our study, the investigators aim to provide information about postural control change after injury by evaluating dynamic balance with the Modified star excursion test. In this way, the intensity of balance exercises can be adjusted while shaping the post-injury rehabilitation program. Evaluated gait analysis and functional results in patients following a designated rehabilitation program after Lisfranc injury. In this study evaluating patients with lisfranc injury treated with 3 different methods (conservative, open reduction internal fixation and primary arthrodesis), significantly reduced joint range of motion, lower walking speed and significantly lower flexion/extension of the midfoot compared to healthy subjects during the pushing phase. These changes may result from loss of muscle strength, differences in surgical methods or different rehabilitation protocols. This change during the pushing phase and the decrease in walking speed negatively affect the lives of patients functionally. Determination of ankle mobility after injury, determination of rehabilitation effectiveness and functional evaluation will be used for the first time in our study for patients with lisfranc injury. In addition to this information, in our study, the investigators aim to evaluate functional capacity with AOFAS (American Orthopaedic Foot and Ankle Society) Midfoot Score , FAOS(Foot and Ankle Outcome Score) and heel-rise tests and be the first study in the literature to apply this test on ligamentous injury. The data obtained after the evaluation may increase the clinical use of these easy and inexpensive tests. Thus, function after Lisfranc injury can be evaluated much more easily, quickly and objectively. Lisfranc injury does not only cause deficits in muscle strength and joint range of motion. Many factors, such as long-term immobilization after injury, damage to structures rich in mechanoreceptors, or surgery, can lead to changes in both sole sensation and joint position sense.
