Kienbock's disease can lead to unsalvageable collapse of the lunate due to avascular necrosis but with reasonably intact cartilage surfaces preserved at the head of the capitate and lunate fossa of the radius. An emerging alternative to traditional treatments for this stage is lunate implant arthroplasty with a hard material. Although, the problem of osteolysis previously seen with silicone implant arthroplasty is expected to be overcome, stabilization of both the implant and the carpus as a whole remains a challenge. The described surgical technique uses a double bundle tendon graft to stabilize the lunate implant against both excessive translational as well as sagittal plane rotational motions. The strategy also stabilizes the scaphoid and the carpus against intercalated segment instability and collapse.
