How to perform an us-guided midfoot injection introduction Foot pain occurs in up to 63% of adult patients, and this percentage will likely increase in the future. Depending on the type of clinic or system, sports medicine providers may be asked to evaluate foot pain in both athletes and adults. It is important to be comfortable performing diagnostic and/or therapeutic injections of the midfoot joints for many sports medicine clinicians.
The midfoot is composed of several small joints that connect the forefoot (the toes and metatarsal bones) to the hindfoot (the heel and ankle bones). These joints include the tarsometatarsal (TMT) joints, naviculocuneiform joining and the intercuneiform joints. They are essential for the stability and function of the foot, allowing for proper weight distribution during walking, running, and standing.
In a healthy foot, these joints move smoothly due to the presence of cartilage, which cushions the bones and absorbs shock. The midfoot refers to the section of the foot that begins at the level of the Chopart joint (also sometimes called the midtarsal joint). It is made up of 2 joints in line, just below and in front of the ankle joint.
The midfoot ends at the Lisfranc joint or tarsometatarsal joint, where the metatarsal bones begin. The second and third TMT articulations normally communicate in all patients and are considered part of the middle column of the foot (Fig. These are also some of the smaller and more difficult joints to access percutaneously, particularly in the setting of severe osteoarthrosis (OA), where residual joint space may measure only a millimeter or two and be complicated by dorsal bridging osteophytosis.
Midfoot joints can also be approached under ultrasound guidance. The approach must be customized to the anatomy of the osteoarthritic joint, avoiding spurring to reach the joint space. Osteoarthritic joints have a large capacity, and one sign that the joint space has been reached is the lack of resistance to introducing the injectate.
