Comparative Study
Comparison of two intramedullary nails for tibiotalocalcaneal fusion: anatomic and radiographic considerations.
Retrograde intramedullary nailing is an established procedure for tibiotalocalcaneal arthrodesis. This study was conducted to see whether, and if so to what extent, nail design modifications would influence the risk to anatomic structures and the bony coverage of the nail base. ⋯ Safer retrograde intramedullary nailing for tibiotalocalcaneal fusion requires knowledge of the structures at risk and appropriate operative technique.

The purpose of this study was to identify subtypes of atraumatic osteoarthritis of the tarsometatarsal joints based on accompanying foot deformities and to determine whether concurrent procedures done for each subtype were effective. ⋯ When feet with atraumatic tarsometatarsal osteoarthritis are classified into four main categories based on associated deformities, appropriate concurrent procedures can be done with high satisfaction and improved function scores. Pes planovalgus feet, in particular, may benefit from concurrent procedures with improved radiographic measures.

We describe a characteristic pattern of bone marrow edema about the foot and ankle seen by MRI in patients who have undergone recent immobilization therapy and investigate potential etiologies as well as possible clinical significance. ⋯ A distinctive pattern of bone marrow edema on MRI of the foot and ankle can be seen on MRI after a variety of weightbearing and nonweightbearing immobilization therapies. This pattern has a consistent appearance on MRI and does not seem to be related to clinical symptomatology. At present, no substantial conclusions can be made regarding the etiology of this phenomenon. However, these bone marrow signal alterations should not mandate further imaging or a change in therapy on the basis of MRI findings alone.

Subtalar arthrodesis is a reliable procedure for pain relief and improved function in patients with isolated subtalar arthritis. Arthroscopic subtalar arthrodesis (ASTA) was designed to improve upon traditional methods by using a minimally invasive technique. However, posterior arthroscopic subtalar arthrodesis (PASTA) has not been described. The purpose of the present study was to investigate the early results of PASTA. ⋯ For surgeons familiar with posterior ankle or subtalar arthroscopy, PASTA offers superior exposure of the posterior talocalcaneal facet, high patient satisfaction, an excellent fusion rate, and less postoperative morbidity for patients with subtalar arthritis.
