A previous study described a new spiral linking technique for tendon repairs and demonstrated that it was strong enough to be used in clinical practice as an alternative to the Pulvertaft tendon weave repair. However the repairs were less stiff, needed slightly more tendon length for the same repair and were a little bulkier. In this study two variables have been changed with a view to improving the spiral technique. At first the number of spirals was reduced consecutively, keeping the same number of standard mattress sutures. Once the optimal number of spirals had been identified, repairs with different numbers of sutures were tested using an alternative cross-stitch technique. The spiral repair technique using two spirals linked with six sutures was at least as strong and stiff as a four-weave Pulvertaft technique and was also easier to do.
