A new instrument: A carpal tunnel knife

Carpal tunnel release by mini palmar incision

“…Carter (1991) used a transverse wrist incision and a special carpal tunnel knife and reported no complication in 100 cases [8]. Some authors have used a short palmar incision for carpal tunnel surgery.…”

“…Several authors tried to combine the simplicity and safety of OCTR with the less tissue trauma and reduced post-operative morbidity of ECTR by using a short incision and open technique. These included a wrist crease mini-incision [8][9][10][11][12], short longitudinal palmar incision [13][14][15][16], and double mini-incision [17]. With these approaches, TCL is classified based on whether CTS is carried out with a conventional instrument or specially developed ones.…”

Mini Open Carpal Tunnel Release Using Knifelight®: Evaluation of the Safety and Effectiveness of Using a Single Wrist Incision (Cadaveric Study)

“…The open release is the most widely accepted technique (Lindau and Karlsson, 1999;Phalen, 1966Phalen, , 1970. Newer techniques include mini open techniques (Bromley, 1994;Klein et al, 2003;Lee and Strickland, 1998), endoscopic assisted release (Agee et al, 1994(Agee et al, , 1995Chow, 1989;Trumble et al, 2002;Tsai et al, 1995), and mini open techniques using specially designed knives, or carpal tunnel-tomes (Avci and Sayli, 2000;Bhattacharya et al, 2004;Carter, 1991;Helm and Vaziri, 2003;Hwang and Ho, 2007;Lee and Jackson, 1996;Lee and Strickland, 1998;Lee et al, 2002).…”

“…However this incision, although small, lies over a fairly sensitive area of the hand and therefore may cause significant pain, thus preventing some patients from going back to their normal activities (Carter, 1991).…”

“…Most mini-OCTRs are performed with a skin incision over the palm so that the motor branch of the median nerve and also the superficial palmar arch can be identified and preserved. However this incision, although small, lies over a fairly sensitive area of the hand and therefore may cause significant pain, thus preventing some patients from going back to their normal activities (Carter, 1991).…”
