Treatment of Lesser Metatarsophalangeal Joint Instability With Plantar Plate Repair: A Systematic Review and Meta-Analysis.

As the condition has become more widely understood and reported, detection of metatarsophalangeal joint plantar plate injuries has increased over time. With the diagnosis of a plantar plate fracture as a type of metatarsalgia, a subset of metatarsalgia, it has become more common, there are several surgical options to treat the condition. A total of 12 studies involving 537 plantar plate tears were included in the plantar plate repair process, whether a dorsal or plantar approach were chosen. The included studies found that improvement in visual analog scale pain improvement and increase in American Orthopedic Foot and Ankle Society ratings of patients were calculated, as shown by summary statistics. With a follow-up out to 2 years, we found that there is a predictable pattern of pain and function in patients undergoing a direct dorsal approach plantar plate repair with a follow-up.

The ability to wear heeled footwear following first metatarsophalangeal joint fusion.

Following the first MTPJ fusion due to the lack of dorsiflexion at the first MTPJ, surgeons have traditionally advised female patients during the consent process that they will have limitations or be unable to wear heeled shoes. Anecdote, surgeons have discovered that some patients were also able to wear heeled boots after fusion surgery.

Finite Element Modeling of Planus and Rectus Foot Types for the Study of First Metatarsophalangeal and First Metatarsocuneiform Joint Contact Mechanics.

Our aim was to create a framework for FE modeling of the medial forefoot so that experimental results of first MTP and first MTC joint loading could be performed with confidence. During quasi-static loading, a custom-built force-controlled cadaveric test-rig was used to derive intracapsular pressure sensor measurements of contact pressure, load, and area. Mesh sensitivity tests and first MTC joint cartilage calibrations of moduli were conducted, as well as best-fit calibrations of moduli for the first MTP and first MTC joint cartilage. According to the first MTP joint at 10 MPa and 20 MPa, respectively, a lower compressive modulus was most suitable to the first MTP, as perplexing with previous experimental results. Mean errors in contact pressures, forces, and places at the first MTP joint and 40 percent, 42 percent, 19%, and 19% at the first MTC joint were 24%, 12%, and 19%, respectively. The present developmental framework may help with future simulation of the first MTP and first MTC joint contact mechanics.
