The traditional transosseus flexor hallucis longus (FHL) tendon
transfer for patients with Achilles tendinopathy requires two incisions
to harvest a long tendon graft. The use of a bio-tenodesis screw
enables a short graft to be used and is less invasive, but lacks
supporting evidence about its biomechanical behaviour. We aimed,
in this study, to compare the strength of the traditional transosseus
tendon-to-tendon fixation with tendon-to-bone fixation using a tenodesis
screw, in cyclical loading and ultimate load testing. Tendon grafts were undertaken in 24 paired lower-leg specimens
and randomly assigned in two groups using fixation with a transosseus
suture (suture group) or a tenodesis screw (screw group). The biomechanical
behaviour was evaluated using cyclical and ultimate loading tests.

Materials and Methods
A new technique of trapeziometacarpal suspension arthroplasty is described. Suspension arthroplasty as a treatment for trape-ziometacarpal arthritis has been studied extensively in the literature, but only using relatively weak forms of tendon-bone fixation. Interference screw fixation for tendon grafts has been proven in other areas of the body such as the knee and shoulder. Our technique involves trapeziectomy and suspension arthroplasty using one half of the flexor carpi radialis tendon, left attached distally. A short segment (approximately 2 cm) is harvested and passed through a 4 mm drill hole in the proximal thumb metacarpal. This is accurately positioned using an initial K-wire and then a cannulated drill. Fixation is achieved with a 4 mm
A 16-year-old professional female ballet student sustained a plantar flexion-inversion injury to her left ankle while dancing. Clinical examination and MRI suggested subluxation of the tibiotalar joint. However, accurate diagnosis was hampered by a transient palsy of the common peroneal nerve. It was subsequently established that she had also sustained a dislocation of her calcaneocuboid joint, a rare injury, which was successfully stabilised by using a hamstring graft. The presentation and management of this rare condition are discussed.
