Brown, PhD, ATC Ankle sprains are among the most common injuries in athletics,1 with a previous history of lateral sprain being one of the strongest risk factors for repeated injury. However, because half of those who sprain their ankle develop CAI, it may be important to observe the other half who have a similar history of ankle sprain but do not subsequently develop CAI.
The plaintiff was in a department store shopping and stated in deposition that she needed to move the seven-foot rolls of rugs by reaching in between the two bars i.
No surveillance recording was available and there were no independent witnesses. The plaintiff indicated that in order to lift a roll of carpet, you had to grab it and pull up [reference to lifting the carpet roll by reaching in between the lower and upper support members.
She described that as she was attempting to lift the carpet roll to pull up, the whole display fell on her feet. She was wearing flip-flops at the time of this accident. The plaintiff described both end cap members dropping on her feet.
However, photographic evidence taken at the scene only indicated that the lower long metal member had dislodged and dropped approximately 11 inches. The entire display did not fall, and the carpet rolls remained upright. In deposition testimony she indicated that it end caps hit and bounced off and went to the ground leaving a contusion on the top of her foot.
However, in a previous audio recorded statement, the plaintiff stated that: This comment by the plaintiff indicated that the bar i. Therefore, this was consistent and argued for the plaintiff keeping her feet flat on the floor after the impact s to one or both feet [ 2 ].
Eight days later, the plaintiff went to an urgent care medical facility. Bilateral inversion and eversion were normal for both the subtalar joints upon examination and all testing was negative for acute trauma to the ATF anterior talofibular and CF calcaneofibular ligaments.
These ligaments resist excessive inversion motion of the foot-ankle complex. However, there was a 1cm by 1cm bruise on the dorsum top of her left foot near the distal end of her 3rd and 4th metatarsal areas i.
This was consistent with a metal end cap member weighing 4. The plaintiff indicated to her physician that she probably had some ankle sprains to both ankles during her early childhood but had not experienced any ankle sprains or other trauma to her ankles or feet since she was about five years old until the ankle trauma that occurred in the store some two months previous.
The plaintiff was prescribed physical therapy to address this lateral-anterior ligament laxity [ 3 ]. After failing conservative treatment, the plaintiff had arthroscopic surgery some five months later to repair her right ankle-foot laxity.
She was written a prescription for physical therapy for both ankles postsurgery. Her left ankle-foot was now also painful.
It was noted in our medical chart review of this case matter that during the initial evaluation at physical therapy post-surgery, the plaintiff indicated to the physical therapist that she had broken her right ankle several years ago and tore several ligaments.
She was unaware of exactly when this incident had occurred, but she indicated that x-rays showed an old fracture. There was no dispute regarding a drop of a metal member to her distal left foot and possibly to both of her feet.
My analysis pointed out that such an event will not produce damage to the ATF and CF ligaments of the right or the left ankle-foot. Her treating physician agreed on this point in deposition testimony.
However, her treating physician opined that her reaction to the pain may have initiated reflexive motions that could have resulted in bilateral inversion ankle sprains.
I pointed out during my deposition testimony that the flexor withdrawal reflex FWR and the contralateral crossed extensor reflex CER would not be expected to operate in such a way so as to result in coincident bilateral inversion ankle sprains.
Her statement argued for stationary feet and in my view, precluded bilateral ankle-foot inversion trauma [ 4 ]. Hertel J Functional anatomy, pathomechanics, and pathophysiology of lateral ankle instability. J Athletic Training For an eversion injury event to be considered, the unwanted motion had to cause excessive eversion during landing or cutting, the athlete had to be unable to continue play following injury, and post-match reports must have described the injury as an ankle sprain.
A single non-contact eversion ankle sprain case study was selected for analysis. A retrospective survey of over patients with inversion injuries of the ankle joint was undertaken to examine the validity of criteria commonly used in an accident and emergency department to assess severity.
Swelling alone is an unreliable indicator of the severity of the injury. Patients with. Biomechanical Analysis of an Ankle Sprain. Injury in one or more ligaments that support the ankle could lead to ankle sprains. Our foot has medial ligaments that support the ankle joint from the inside against forces of inversion.
On the outside, the lateral ligaments function the same way. The most common ankle injuries are ankle sprain and ankle fracture. This review discusses treatments for ankle sprain (including the management of the acute sprain and chronic instability) and ankle fracture, using evidence from recent systematic reviews and randomized controlled trials.
A retrospective survey of over patients with inversion injuries of the ankle joint was undertaken to examine the validity of criteria commonly used in an accident and emergency department to assess severity.
Swelling alone is an unreliable indicator of the severity of the injury. Patients with. The final section offers a demographic summary of the injuries: length of time on the job, age, and gender. This information can assist organizations in identifying injury trends.
The injury analysis report will assist an organization in identifying factors that contribute to injuries that are occurring in the workplace.
