Lisfranc (Midfoot) Injury: Cause & Treatments

Lisfranc or midfoot injuries are often the results of broken bones in the midfoot or torn ligaments. Lisfranc injuries can vary from complex to simple depending on the number of joints and bones that are involved. Many patients often mistaken their midfoot injury to that of a simple sprain. As a result, many choose to self-medicate with pain relief cream. However, Lisfranc injury is not as simple as it seems and may even require surgery in some cases.

Located in the midfoot are clusters of small bones forming an arch at the top of the foot. There are five long metatarsal bones extending to the tones and ligaments and tendons hold the bones in place. However, there are no connective tissues holding the first metatarsal to the second metatarsal.

Lisfranc injuries can occur due to either direct or indirect trauma. Direct trauma is often result of an external force striking the foot while an indirect trauma occurs due to a force transferring to the stationary foot that deforms the foot. The foot is a smart system that is divided into three different sections namely the hindfoot, midfoot and forefoot. The role of the midfoot is to translate force and provide rotational stability and it is the keystone for plantar flexion and dorsiflexion. Therefore with a lack of dorsal support, the load acting on the foot is sufficient to cause dorsal displacement, leading to broken bones and/or ligaments.

The earlier a Lisfranc joint injury is diagnosed, the better it is for both patient and doctor. An initial clinical evaluation involving radiographs such as x-rays and MRI will be performed to indicate the probability of a mild, moderate or complex sprain. If diastasis is not present, immobilisation will be needed. This will include the usage of an immobilisation cast for a period of four to six weeks followed by limited movements. After six weeks, rehabilitation exercises need to start immediately. This is due to the bone being a piezoelectric material and will resorb after periods of inactivity.

If surgery is needed, it will be performed within 24 hours of the injury or after 10 days to allow for the drainage of bodily fluid due to swelling. Kirshner wires will be used to fix the bones together and bone fragments will be removed. After surgery, patients need to be immobilised in a cast for up to 12 weeks with minimal movements.

Some people will no longer be able to return to pre-injury levels of activity after a midfoot injury despite advancement in medical technology.


Introduction To Commonly Used Protective Gears

Warehouses are regulated by Occupational Health and Safety Act (OHSA) standards to protect warehouse workers from work injuries. There is a high risk of injury for workers working in such environment with all the machines and wooden pallets. As such, workers are required to don protective gears when working in warehouses for their own safety. In this article, we will be looking at some of the commonly used protective gears out there.

Safety shoes

Safety shoes are often a compulsory protective gear that is required in places that poses a risk for foot injuries. Safety shoes have steel toes of different grades and they are able to protect against electrical hazards. The steel toes will protect the wearer against any impact or punctures from falling equipment and protect them from a full electrical shock. They also offer anti slip soles which prevents the wearers from slipping and falling in the workplace. Some safety shoes are also free of static so that they do not interfere with sensitive equipments in the workplace.

Safety eyewear

Our vision is probably the most important of our senses and we should always protect our eyes. In workplaces which pose a safety hazard to the eyes, safety eyewear should always be worn. Safety eyewear protects against accidental chemical splashes and dust irritants. They also help to protect against any flying particles.

Safety helmet

Safety helmets help to protect the wearer against any accidental knocks against hard surfaces and debris. Some safety helmets are also electrical insulators, protecting the wearer against accidental contact with an exposes electrical cable. However, safety helmets are unable to protect against any impact such as a falling object.

Protective gloves

Protective gloves provide a barrier between the hands and the objects, protecting against any accidental cuts or nicks. Since the work equipment may be rusty, any cuts can cause nasty infections leading to more serious complications. Workers who are required to work on equipment for long periods of time are required to wear gloves.

Protective earplugs

Workers who work in places with loud machinery are required to wear protective earplugs to protect their ear drums. Prolonged periods of exposure to loud machinery will cause the ear drums to burst and subsequently going deaf.

Above is the introduction to common protective equipment in the workplace. There are measures in place to protect the workers and as a worker; you are required to comply with the rules and requirement. Do not think that using protective equipment is time consuming. It will protect you in the most unexpected situation.
