The 3-rocker mechanism of gait provides a framework to understand why patients have mechanical metatarsal pain and to differentiate between the various types of metatarsalgia. Clinical examination of the patient together with radiological findings allows identification of the type of metatarsalgia and the pathomechanics involved, and the planning of surgical treatment. Second-rocker/nonpropulsive metatarsalgia is related with an abnormal inclination of a metatarsal in the sagittal plane, either anatomic or functional (equinism). Third-rocker/propulsive metatarsalgia is related to an abnormal length of a certain metatarsal with respect to the neighboring metatarsals in the transverse plane.

Article Synopsis
  • - High-resolution ultrasound (US) is an effective tool for examining soft tissue issues in the foot and ankle.
  • - It is more affordable, accessible, and convenient than MRI, and it allows for real-time viewing of the area.
  • - US is particularly good at assessing injuries to tendons, ligament tears, plantar fascia, peripheral nerves, and various causes of metatarsalgia.

Article Synopsis
  • Foot and ankle disorders are frequent during pregnancy due to changes in weight, hormones, and fluid balance, leading to issues like varicose veins, DVT, and tendon injuries.* -
  • Ultrasound is highlighted as a safe and non-invasive diagnostic tool, particularly effective for assessing venous conditions and differentiating causes of edema; it provides real-time imaging without radiation.* -
  • The technology also aids in diagnosing musculoskeletal problems and detecting foreign bodies, making it a cost-effective and accessible option for improving patient outcomes in pregnant women.*

Article Synopsis
  • Doctors are using a new method called minimally invasive surgery (MIS) to fix a foot problem called hallux valgus (HV), which makes the big toe point outward.
  • They studied how this surgery affects pressure on different parts of the foot using some special tools and fake legs (cadavers).
  • The results showed that the surgery didn't change the pressure on one side of the foot, but moving the bone a little in different directions did change the pressure a bit!

Sonographic anatomy and technique to image the plantar digital nerves and aid identification of a Morton's neuroma.

Ultrasound

Article Synopsis
  • The forefoot has a tricky structure, and using ultrasound (a special imaging technique) to see the nerves and diagnose conditions like Morton's neuroma can be tough.
  • This paper explains how to properly use ultrasound to look at the muscles, tendons, and nerves in the forefoot, helping with better diagnosis.
  • By understanding the anatomy and how it looks on ultrasound, doctors can better identify problems in the forefoot and decide how to treat patients.

Metatarsalgia occurring in individuals with pes cavus is typically associated with abnormal loading patterns in the forefoot resulting from structural alterations. Simultaneously, the frequent overstress of the plantar fascia (PF) caused by the persistence of this foot deformity may further exacerbate the chronic pain induced by metatarsal overload. We aimed to investigate and quantify the effects of PF stiffness on the internal biomechanics of pes cavus using a computational modelling approach.
