Osteoid osteoma of the calcaneus: percutaneous radiofrequency ablation.

Osteoid osteoma of the foot can pose particular problems in diagnosis, especially when positioned in a juxta-articular location. It can cause reactive synovitis and simulate arthritis without periostitis. An atypical presentation may delay diagnosis and thus delay treatment.

Floating-toe deformity as a complication of the Weil osteotomy.

Background: The Weil osteotomy for treatment of central metatarsalgia is an oblique osteotomy of the metatarsal neck and shaft parallel to the ground that provides controlled shortening of the metatarsal without additional depression. It offers many advantages over more traditional osteotomies, including stability and a large area of bone-to-bone contact. However, a floating-toe deformity appears to be a common complication after this osteotomy.
