“…Hamada et al. 6 reported successful treatment of severe contracture of intrinsic plus hand with an Ilizarov mini fixator after reducing the tension on the extrinsic muscle by PRC. Similarly, we performed PRC first to reduce the shortening of the extensor and flexor tendon and wrist contracture.…”

Wide-awake local anesthesia has many advantages. We describe a new method to use wide-awake local anesthesia with more flexibility. A 32-year-old man with a severe right-hand contracture after an iatrogenic tourniquet accident during an anterolateral thigh flap for a partial hand amputation underwent contracture release using external fixation after proximal row carpectomy and subsequent tenolysis. We performed most of the tenolysis procedure under general anesthesia and the final stage with an intraoperative assessment of active finger movement and dissection under local anesthesia. He regained his grip strength 2.5 years post-injury. General anesthesia is useful to treat a surgical site with extensive hard scars, whereas local anesthesia is useful for adjusting tension in an awake patient. The indication for wide-awake surgery is yet to be established; our method of combining general and local anesthesia in the tenolysis procedure illustrates the possibilities in expanding this method.

“…The Ilizarov mini-fixator is an external fixator developed at the Ilizarov Institute, Russia in the 1990s 9,10) and is currently used worldwide [11][12][13][14][15][16][17] . The Ilizarov mini-fixator has been used not only for fracture treatment of the digits 18) but also for the release of joint contractures 13) , post-traumatic bone lengthening 17,19) , lengthening of bones and soft tissue in congenital malformations 9,14) , fractures of the foot 12,15) , and fixation after forearm osteotomy 16) .…”

“…The thickness of the pin and the diameter of the rod can be changed depending on the application. When a heavy load is applied to the ex- ternal fixator such as for contracture treatment, the Ilizarov mini-fixator with a larger rod (4 mm diameter) is also used 13,20) . When the bone fragment to be fixed is small, the number of pins may be reduced, and a configuration in which two pins are fixed per unit is also used.…”

Objectives:The Ilizarov mini-fixator, an external fixator developed for digits, has a structure different from that of general unilateral external fixators. The purpose of this study was to provide information for clinical external fixator selection by clarifying the biomechanical properties of the Ilizarov mini-fixator. Methods: Three types of loads were applied to the fracture fixation model using a carbon fiber cylinder as the bone model: axial pressure, 4-point bending, and torsion. Ilizarov mini-fixators with six 1.5 mm pins (6-pin group), four 1.5 mm pins (4-pin group), and four 2.0 mm-threaded-pins (2 mm-pin group) and a group using a 1.5-mm plate (plate group) were set, and the stiffness was compared between these four groups. Results: Compared to the 6-pin group, which is the basic configuration of the Ilizarov mini-fixator, the 4-pin group had lower stiffness against axial load and bending, and there was no significant difference in stiffness against torsion. The 2 mm-pin group had high stiffness against axial load and bending and low stiffness against torsion. The plate group exhibited high stiffness against axial pressure and low stiffness against bending and torsion. Conclusions: The Ilizarov mini-fixator is a reasonable option for fixing small phalanges. However, other options should be considered for the fixation of larger bones with higher loads. In particular, a configuration with fewer pins such as the 4-pin model may have insufficient strength during early postoperative exercise, even for fixing the phalanges.
