Abstract

|
|
Many years have been spent in the study on the repair of the injured tendons by many investigators, still leaving many controversial opinions about it.
The author has been trying to establish any definite theory on the process of the repair of the injured tendons, taking into account the fact that there are many questionable points of view in regard to the primary origin of regeneration of tendons, relationship with and without tendon sheath injury and histological changes of regeneration after the injury.
As a means to this end, the author has carried out the following experiments in 30 rabbits which were devided into following two groups of tendon resection, namely
group 1-resected only Achilles tendon in length of 0.5, 1.0 and 2.Ocm respectively without tendon sheath at the same level
group 2-resected Achilles tendon in length of o. 5, 1.0 and 2.Ocm respectively with tendon sheath at the same level.
Repair processes were observed macroscopically and microscopically on the 3rd, 16th, 22nd, 32nd, 39th, 56th and 84th day after resection of Achilles tendons and the experimental results are summarized as follows:
1 Regeneration of tendons is noted along the margins of both Achilles tendons following surgical resection in each experimental group.
2. Regenerative activity of tendons started from three days. and completed by eight weeks after resection.
3. No difference in histological findings of regeneration of the tendon was seen relating to the distance of tendon defect following various length of surgical resection of Achilles tendon.
