Abstract
BACKGROUND
Soft tissue defects in the achilles tendon region occur after trauma, but also as a complication after open recon- struction of the tendon with subsequent infection.
OBJECTIVES
Recommendations for the treatment of soft tissue injuries involving the Achilles tendon are presented.
MATERIALS AND METHODS
A search of the German, French and English literature on reconstruction of soft tissue defects of the Achilles tendon region was performed, which were differentiated into singular and combined tendocutaneous defects. Combined defects were further subdivided into three reconstructive principles: a simple soft tissue reconstruction without tendon repair or a combined reconstruction of the soft tissue as well as the tendon using either a vascularized tendon transplant or an avascular tendon graft.
RESULTS
Local and distally-based pedicled flaps include a relatively high risk or perioperative morbidity, whereas free flaps are described with significantly lower complications rates. Therefore, the authors prefer free flaps for reconstruction. Potential donor sites are the Medial Sural Artery (MSAP-) flap for smaller defects or free fasciocutaneous or muscle flaps in patients with large defects. The standard for tendocutaneousreconstructions is the free anterolateral thigh flap including vascularized fascia. Non-vascularized tendon grafts are frequently applied from the flexor hallucis longus- or peroneus brevis tendon.
CONCLUSIONS
Reconstructions over the Achilles tendon require thin and stable reconstructions that additionally allow slippage of soft tissues. Moreover, the use of normal shoes should be possible. The postoperative strength and range of motion of the ankle joint show comparable functional results after vascularized and non-vascularized tendon reconstruction.
