Recent studies conclude that a new technique for tendon transfers, the side-to-side tenorrhaphy by Fridén (FR) provides higher biomechanical stability than the established standard first described by Pulvertaft (PT). The aim of this study was to optimize side-to-side tenorrhaphies. We compared PT and FR tenorrhaphies as well as a potential improvement, termed Woven-Fridén tenorrhaphy (WF), with regard to biomechanical stability. Our results demonstrate superior biomechanical stability and lower bulk of FR and, in particular, WF over PT tenorrhaphies. The WF and FR technnique therefore seem to be a notable alternative to the established standard tenorrhaphy as they display lower bulk and higher stability, permitting successful immediate active mobilization after surgery.

ABSTRACT Objective: The purpose of this study was to demonstrate, in a case series, a new sacrectomy technique using an iliac crest dowel graft from a cadaver. Study design: Report of a case series with description of a new surgical technique. Methods: The technique uses four bars to support the posterior spine and a dowel graft in the iliac wings, with compression of the spine and pelvis above it, to support the anterior spine. Three cases were operated on, and in all of them, a vertebrectomy was used. Results: In the first two cases, the technique was performed as a two-stage surgery. The first stage was performed via the anterior and peritoneal access routes, and the second stage via the posterior access route. In the third case, retroperitoneal access via the anterior route meant that the technique could be performed in one stage, resulting in an overall reduction in surgical time (1250 vs. 1750 vs. 990 minutes, respectively). Conclusion: The new technique enables fixation with biomechanical stability, which is essential to support the stress in the lumbosacral transition and promote earlier rehabilitation. Level of evidence IV, case series.

23 tendon transfers in the hand and forearm were performed using a polyester mesh sleeve to reinforce conventional suture techniques. All transfers were mobilized with active flexion and extension within 3 days of operation. Excluding one rupture (due to extreme unintentional loading) and depending on the type of transfer used, a mean of between 69% and 78% of the final active range of motion was obtained 1 month post-operatively. With the exception of transfers for wrist extension, the mean final active range of motion amounted to between 91% and 100% of the available passive range of motion and between 75% and 100% of the corresponding “normal” active range of motion in the opposite hand. The mean final active range of motion after reconstructions for wrist extension amounted to 85% of the passive range of motion and to at least 80% of the maximum range of motion potentially available with the transfers used. The results indicate that early active mobilization after tendon transfers may offer significant advantages in terms of quicker and simpler rehabilitation as well as improved results.
