Plate-augmented tension band wiring for arthrodesis of the proximal interphalangeal and metacarpophalangeal joints: a case series

Abstract

Dorsal minimally invasive hook of hamate fixation was performed by a single operator on ten hands. The anterior dissection revealed the absence of vascular, nerve or tendon injury in all cases. The screw length and position were correct in all cases with bicortical fixation in the tip of the hook. Mean fluoroscopy duration was 3 minutes, 23 seconds. The dorsal incision was always less than 10 mm long.Our cadaveric study confirms that the dorsal percutaneous approach is a reliable method and provides safe fixation of non-displaced fractures of the hook of hamate. Knowing that, we recommend that primary surgical fixation should be considered over excision in order to allow early return to activities with decreased risk of complications related to the ulnar neurovascular pedicle. However, careful evaluation of clinical outcomes is needed to confirm this approach. ReferencesBansal A, Carlan D, Moley J, Goodson H, Goldfarb CA.

Arthrodesis of the Proximal Interphalangeal Joint of the Finger—A Biomechanical Study of Primary Stability

“…In particular, in trauma cases with a destroyed PIJ such as transarticular amputations, implants which can be applied quickly and induce less additional soft tissue damage are chosen. Those implants, typically k wires, do not apply any compression [ 9 ]. Plate arthrodesis is of particular importance in the case of segmental bony defects, non-unions and/or after failed endoprosthesis treatments as it can be easily combined with bone grafts, which in turn enable efficient length maintenance, and thus, less shortening of the finger [ 10 ].…”
