Hand extensor compartments8/13/2023 ![]() Further clinical and biomechanical investigations would be advisable to clarify this complex issue.Įxtensor tendon injuries (ETIs) to the hand and forearm are frequently seen in clinical practice nonetheless, these kinds of lesion are sometimes underestimated compared with those of flexor tendons. Despite recent research findings, a lack of evidence-based knowledge is still observed in surgical treatment and postoperative management of ETI. Many surgical techniques have been proposed over the time and with favorable results if the tendon injury is not underestimated and adequately treated. As a general rule, an attempt of conservative treatment should be performed when the lesion is expected to have favorable result with nonoperative procedure. Both conservative and surgical management can be indicated in ETI, depending on the anatomical zone and on the characteristics of the injuries. Injury classification into anatomical zones and the evaluation of the characteristics of the lesions are considered key points to select the appropriate treatment for ETI. During last decades the evolution of surgical techniques and rehabilitative treatment protocol led to gradual improvement in clinical results of ETI treatment and surgical repair. ![]() A careful clinical history and assessment still remain the first step for the diagnosis, followed by US and MR to confirm the suspect of ETI or to investigate some doubtful conditions and rule out associate lesions. Anatomical knowledge and the understanding of physiopathology of extensor tendons are essential for an accurate diagnosis of extensor tendon injuries (ETIs) of the hand and wrist, because these lesions are complex and commonly observed in clinical practice. The extensor apparatus is a complex muscle-tendon system that requires integrity or optimal reconstruction to preserve hand function.
