"Mini-open" repair of acute tendo Achilles ruptures--the solution?

BACKGROUND: The standard surgical exposure for repair of acute tendo Achilles rupture gives favourable results, but such extensive exposure increases the possibility of peritendinous adhesion, wound breakdown and infections which increases morbidity and impairs functional outcome. Open repair also increases post-operative hospital stay and hence encroaches on valuable bed space availability. To evade this mini-open technique was developed which provide anatomic apposition of the tendon ends and minimal damage to epitendon. METHODS: We describe a retrospective case series of 21 patients who were treated with mini-open technique as a day case, between 2004 and 2007 operated by a single surgeon. They were followed up for a year. Both the Leppilahti score and the American Orthopaedic Foot and Ankle Society for the Ankle Hind foot Clinical Rating System (AOFAS) were calculated. The patients (8 males and 13 females) had a mean age of 43.4 years. Post-operatively the leg was placed in an air cast boot with 3 heel wedges allowing 30 degrees of plantar flexion. The foot is brought into plantigrade position by 6 weeks with serial removal of heel wedges followed by a rehabilitative training programme. RESULTS: There was one superficial infection which settled on oral antibiotics, no re-rupture or sural nerve involvement was noted in this series. All patients returned to previous work and sports activities. All patients scored above 90 in the American Orthopaedic Foot and Ankle Hind foot Clinical Rating System and on the Leppilahti Scoring System. Mini-open procedure is an excellent alternative to open exposures reducing the inpatient post-operative stay. All patients were discharged home on the same day of the procedure. CONCLUSION: Our pilot study has helped us to implement a standardised pathway by which patients have benefitted with improved rehabilitation and return to their pre-injury status.

The optimal assessment of the rheumatoid arthritis hindfoot: a comparative study of clinical examination, ultrasound and high field MRI.

OBJECTIVES: The aim of this pilot study was to compare clinical examination (CE) and ultrasound (US) with high field MRI (as the reference standard) for the detection of rearfoot and midtarsal joint synovitis and secondly tenosynovitis of the ankle tendons in patients with established rheumatoid arthritis (RA). METHODS: Patients with RA (as determined by the modified American College of Rheumatology (ACR) criteria) with symptoms of midfoot and rearfoot disease were recruited. Demographic data were collected. All underwent CE, US and high field MRI (with intravenous gadolinium contrast) of their right foot. Percentage exact agreement (PEA), sensitivity and specificity were calculated for CE and US when compared to MRI. Inter-reader reliability for CE and US was also assessed. RESULTS: Compared to the gold standard of MRI, for CE (joint synovitis) the ranges for sensitivity, specificity and PEA were 55-83%, 23-46% and 46-60%, and for US were 64-89%, 60-80% and 64-78%, respectively. Compared to the gold standard of MRI, for CE (tenosynovitis) the ranges for sensitivity, specificity and PEA were 0-100%, 20-91% and 55-91%, and for US were 0-67%, 86-100% and 59-86%, respectively. CONCLUSION: CE was sensitive but US more specific in identifying hindfoot pathology in RA when compared to the reference standard of MRI. There was poor interobserver variability between ultrasonographers suggesting a need for standardisation of acquisition and interpretation of US images of the hindfoot.

Irreducible Galeazzi injury.

We present a case of a Galeazzi-type of fracture dislocation with an irreducible distal radioulnar joint. This is illustrated by intraoperative pictures which may assist others who find themselves faced with this injury.
