Introduction:

All reported RA forefoot deformities in the literature so far have arisen from shoe wearing populations. Our aim in this study was to compare hallucal deformities seen in a shod to a non-shod population.

Methods:

A case-control study was undertaken in two specialist foot and ankle units, one in India and one in the UK. All patients suffering from RA and attending for consideration of forefoot surgery from January 2007 to October 2013 were included in this study. Standardized anteroposterior weight bearing radiographs were obtained to measure the hallux valgus, inter-metatarsal and metatarsus primus varus angles.

Introduction:

There are concerns with the use of the Shannon burr in calcaneal osteotomies entered from the lateral side, with the medial structures possibly at risk when performing the osteotomy of the medial calcaneal wall. Our aims with this study were to investigate the neurovascular relationships with the calcaneal osteotomy performed using a Shannon burr.

Methods:

This study was performed at the anatomy department, University of Sussex, Brighton. There were 13 fresh frozen below knee cadaveric specimens obtained for this study. The osteotomy was performed using a Shannon burr using a minimally invasive technique. The neurovascular structures were then dissected out to analyse their relation and any damage.

The incidence of venous thromboembolism (VTE) is unknown in elective foot and ankle surgery. In March 2010 we surveyed the current practice in VTE prophylaxis in elective foot and ankle surgery amongst members of the British Orthopaedic Foot and Ankle Society (BOFAS).

The response rate was 53%. The total the number of elective foot and ankle operations performed by the surveyed group was 33,500 per annum. The perceived incidence of DVT, PE and fatal PE was 0.6%, 0.1% and 0.02%. In our study the number of patients needed to treat to prevent a single fatal PE is 10,000 although this figure is open to significant bias.

The National Institute for Health and Clinical Excellence (NICE) recently published guidelines on reducing the risk of venous thromboembolism in surgical patients. These guidelines cover all surgical inpatients and uses data extrapolated from other groups of patients. We question the applicability of these guidelines to patients undergoing elective foot and ankle surgery. We consider that this data justifies the prospective study of the incidence of VTE in patients undergoing elective foot and ankle surgery, without the use of chemical thromboprophylaxis.

The aetiology of hallux valgus is well published and largely debated. Hypermobility at the TMTJ was initially described by Morton, but it was not till Lapidus that its association with hallux valgus was hypothesized. However, little has been published on the anatomy of the tarsometatarsal joint. Our aim was to determine whether there was an anatomical basis for the coronal hypermobility in hallux valgus.

Method

Anatomical dissection was completed on 42 feet from 23 bodies. Presence of hallux valgus was noted (displacement of sesamoids). Measurements and photographs were taken of the first tarsometatarsal joint and all differences noted.

Observations

The TMTJ articular morphology is variable. There were 3 separate subtypes identified of the metatarsal articular surface.
