Reply: About the Arterial Anatomy of theAchilles Tendon

To the Editor, Clinical Anatomy:

We would like to thank Professor Matusz for his letterpertaining to our recently published study ‘‘The arterialanatomy of the Achilles tendon: Anatomical study and clini-cal implications’’ (Matusz, in press). In his letter, ProfessorMatusz kindly provides his own data to corroborate that ofour own, showing that it is indeed the midsection of theAchilles tendon that has the poorest vascularity and is thesite of greatest risk for devascularization and/or tendonrupture. Although our cohort comprised cadavers of agerange 60–85, it is certainly interesting to know that this rel-ative deficiency of the vascularity of the midsection of theAchilles tendon is present in all age ranges, as early as inthe fetal studies by Matusz. This demonstrates that it is nei-ther a degenerative vascular process nor a secondary effectfrom tendon degeneration, but rather this is part of theembryology of the Achilles tendon.

Professor Matusz also discusses the process of suralnerve harvest, a technique that does involve open incisionin the vicinity of the lateral margin of the Achilles tendon.In our manuscript, we were eager to highlight that it indeedis this lateral margin that is of importance in preserving theblood supply from the peroneal artery, its sole source inthis region. In commenting that all surgical approaches tothis region should avoid the lateral margin where possible,

we used Achilles tendon lengthening as a case example.However, there are numerous surgical interventions thatwarrant incisions in this region, and sural nerve harvest iscertainly one of these. Open reduction of fractures, fasciot-omies, and tendon transfers about the ankle are othersurgical procedures that necessitate care in avoiding theperoneal artery in this region.
