Lesser toe proximal interphalangeal joint arthrodesis is a common forefoot procedure for correction of claw toe deformities. The most common method of fixation is with k-wires. Although this is a very cost-effective method of fixation, well-known disadvantages include pin site infection, non union, wire migration and the inconvenience to the patients of percutaneous wires for up to six weeks. For these reasons, intramedullary devices for joint fixation without crossing the distal IP joint have been developed. Many different designs are currently available. The Smart Toe prosthesis which has appeared as a type I and II, is one such implant. In two recent studies using type I, the use of this implant is advocated. We wish to present our experience with the use of the Smart Toe II. In this retrospective study we present a radiological review of 46 consecutive cases in 25 patients who underwent lesser toe interphalangeal arthrodeses using the Smart Toe II implant between July 2010 and November 2014 by the senior author. There were 7 (28%) male and 18 (72%) female patients. Post operative radiographs, taken at a mean follow up of 6 months, were reviewed for non-union, migration and implant failure.Introduction
Methods
Lisfranc joint injuries account for only 0.2% of all fractures but early diagnosis improves the chances of a better outcom]. Radiographic signs, such as diastasis (>2mm) of the 1–2 interspace, are subtle and. often missed, leading to a poorer outcome. We present a new radiographic sign, less likely to result in missed diagnoses. Null nypothesis: The intermetarsal angle remains unchanged in Lisfranc injuries. A series of radiographs demonstrating Lisfranc injury were interspersed with normal and postoperative cases. Evidence of fixation was obscured. A selection of Foundation and Core Trainee medical staff measured the intermetatarsal angle (IMA) on two separate occasions. The measuring technique was demonstrated with no explanation for the reason behind the measurement.Introduction
