This review article describes the contribution of Australian authors to the basic science and clinical management of flexor tendon injuries.

Achilles' death: anatomical considerations regarding the most famous trauma of the Trojan War.

In Greek mythology, Achilles was a hero of the Trojan War, the central character and greatest warrior of Homer's Iliad. As Achilles died because of a small wound on his heel, the term "Achilles' heel" has come to mean a person's principal weakness. But is the human heel a really vulnerable part of our body? Could a non-poisonous arrow have caused Achilles' death? Should an arrow be necessarily poisonous in order to cause a lethal heel would? The purpose of this effort is to explain, from an anatomic point of view, how Achilles heel wounding could have led to his death. The Achilles tendon is the strongest, largest and thickest tendon in the human body and plays an important role in the biomechanics of the lower extremity. The blood supply of the tendon is from the peroneal and posterior tibial arteries. It is quite likely that the arrow which killed Achilles was poisoned. This supposition could be of course enough to cause his death. In case the arrow was not poisoned a rupture of the posterior tibial artery by the arrow could have caused a bleeding, but it seems unlikely for such a bleeding to be lethal. Moreover, a combination of these two theories could have also taken place, i.e. a poisoned arrow traumatizing the posterior tibial artery and hence causing rapid diffusion of the poison as well as bleeding. Furthermore, infectious and/or immunologic bases regarding Achilles' death could be considered. In our opinion, a poisoned arrow was probably the crucial factor leading to the famous inglorious death of this famous glorious Homeric hero.

History and evolution of the Kessler repair.

The "grasping technique" described by Isidor Kessler and Fuad Nissim in 1969 is a popular method of flexor tendon repair. Different authors have modified this technique to the point where the so-called "modified Kessler technique" bears little resemblance to the original description. This article sheds light on the life and contributions of Isidor Kessler, and examines the evolution of the Kessler technique and the origin of grasping and locking tendon repairs. We also discuss the problems associated with eponymous descriptions of tendon repair techniques and propose an alternative descriptive system.

Grammont's idea: The story of Paul Grammont's functional surgery concept and the development of the reverse principle.

BACKGROUND: The increased use of the reverse prosthesis over the last 10 years is due to a large series of publications using the reverse prosthesis developed by Paul Grammont. However, there is no article reporting the story of the concepts developed by Grammont. QUESTIONS/PURPOSES: The purposes of this review are to describe the principles developed by Grammont, the chronology of development, and the biomechanical concepts and studies that led to the current design of the reverse prosthesis. METHODS: We selectively reviewed literature and provide personal observations. RESULTS: From phylogenetic observations, Grammont developed the principle of functional surgery applied to the rotator cuff tears. To increase the deltoid lever arm, he imagined two possibilities: the lateralization of the acromion, which facilitates the action of the rotator cuff, and the medialization of the center of rotation, which has been developed to respond to situations of rotator cuff deficiency. Grammont proposed the use of an acromiohumeral prosthesis, which was quickly abandoned due to problems of acromial loosening. Finally, Grammont used the principle of reverse prosthesis developed in the 1970s, but made a major change by medializing the center of rotation in a nonanatomic location. In 1985, Grammont validated the concept by an experimental study and the first model using a cemented sphere was implanted. CONCLUSIONS: The development of the modern reverse prosthesis is the result of the intellectual and experimental work conducted by Grammont and his team for 20 years. Knowledge of this history is essential to envision future developments.

History of flexor tendon repair.

The first issue of Hand Clinics published 20 years ago was devoted to flexor tendon injuries. This was most appropriate, because no subject in hand surgery has sparked more interest or discussion. That inaugural issue included excellent presentations on the basic science of tendon injuries (anatomy, biomechanics, nutrition, healing, adhesions) and the clinical practice of tendon repair. Of interest, there was no presentation on the fascinating history of flexor tendon surgery. It is most appropriate, therefore, that this current update of the flexor tendon begins with a historical review of the evolution of flexor tendon repair.

No man's land revisited: the primary flexor tendon repair controversy.

New surgical procedures, novel concepts, and/or the presentation of very good results with an apparently discredited technique meet varying degrees of resistance among the establishment of any profession. In hand surgery this phenomenon was exemplified in a striking fashion with the presentation of a controversial report entitled, "Primary repair of flexor tendons in no man's land" by Kleinert, Kutz, Ashbell, and Martinez of Louisville, KY, at the 1967 American Society for Surgery of the Hand (ASSH) annual meeting. The discussant, Joseph Boyes, expressed such skepticism that a special ASSH committee was appointed to go to Louisville and review the results to determine if they were as good as claimed. They were, and today primary flexor tendon repair is the procedure of choice for most flexor tendon lacerations.

Enhanced tenodesis for retrocalcaneal surgery.

Retrocalcaneal surgery is complex and difficult. Over the years, many different approaches to retrocalcaneal surgery have been described. Partial or total release of the tendo Achillis is often necessary, with reattachment being of paramount importance to allow for optimal function following surgery. Although numerous anchoring devices have been introduced for tendo Achillis reattachment, the authors have found the DePuy TiMAX Spider Plate (DePuy ACE, Warsaw, Indiana) to be superior. This article describes the Spider Plate and associated surgical technique, which have greatly enhanced the outcome of retrocalcaneal surgery.

[The history of flexor tendon surgery]. / L'histoire de la chirurgie des tendons fléchisseurs.

Flexor tendon injuries were already treated in antiquity by Hippocrates, Galien and Avicenne. Since the Renaissance, other surgeons have attempted to repair flexor tendon injuries, but without success due to problems related to unsuitable materials and ignorance of the basic rules of asepsis and the absence of antiseptics until the second half of the 19th century. The first successful flexor tendon grafts in man were performed by K. Biesalski in 1910, E. Lexer in 1912 and L. Mayer in 1916. These three authors published their series of grafts and described in detail the anatomical, physiological and technical principles to be respected. St. Bunnell, in 1918, developed various pull-out direct suture procedures, but faced with the problems of adhesions, he abandoned this technique and proposed not to repair flexors in the digital tunnels but to graft them. He defined the famous zone which he called No man's land, which subsequently became Claude Verdan's zone II, in 1959. In 1960, C. Verdan published his first series of sutures maintained by 2 pins in zone II with comparable results to those obtained after grafting. In 1967, H. Kleinert, with his mobile suture, became the leader of direct tendon repair in zone II. 2-stage grafts were introduced in 1965 under the impetus of J. Hunter, who revised and popularized the studies conducted by A. Bassett and R.E. Caroll in 1950.
