What bones are fused in a 4 corner Fusion?

Thereafter, the four bones to be fused—that is, the lunate, capitate, triquetrum, and hamate—were exposed and the intercarpal articular surfaces removed using a combination of fine rongeurs and osteotomes, leaving bleeding bone exposed.

How painful is a 4 corner Fusion?

Results: All patients experienced improvement of their pain, function, range of motion and grip strength (p < 0.05). Twenty-three patients (74 %) reported no pain, and eight patients reported mild, occasional pain. Twenty-one patients (68 %) were able to do usual and specific activities.

What is a 4 corner fusion wrist?

Four corner fusion, or partial wrist arthrodesis, is a procedure which involves resection/removal of the scaphoid bone and fixation of the remaining wrist bones with a plate or wires. The procedure is usually performed due to wrist arthritis or due to scaphoid collapse.

What is STT fusion?

STT fusion involves joining the three bones together to prevent movement at the joint. The operation involves the surgeon removing the surfaces of the joint. A small bone-graft is taken from the hip-bone (ileum) and this is packed into the STT joint to encourage the bone surfaces to join together.

What is the recovery time for proximal row Carpectomy?

By six weeks, no immobilization is necessary and an aggressive strengthening program can be initiated. Three months postoperatively, the patient can return to full unrestricted activities.

How long does a wrist replacement last?

On average, a wrist replacement can be expected to last 10 to 15 years with careful use. As with all implants, long-term follow up is advised. Generally, follow up every year or every 2 years will identify any developing conditions or problems.

What happens if scaphoid bone dies?

Avascular necrosis occurs when part of the scaphoid bone dies because of the loss of blood flow. This can eventually result in fragmentation and the collapse of the bone. Its presence also makes repair of the scaphoid much more difficult.

What is four-corner fusion with scaphoidectomy?

Four-corner fusion with scaphoidectomy is preferred over proximal row carpectomy (PRC) when capitolunate arthritis is present or when the patient is younger than 40 years of age. Fixation options for four-corner fusion include K-wires, staples, headless compression screws, or intercarpal fusion plates. 1

Is a four-corner fusion of the scaphoid and spider plate satisfactory?

Nonunion, particularly around the triquetrum, continues to be a problem, but it may be that this bone should be excised along with the scaphoid, resulting in a three-part fusion only. Alternatively, a simple capitolunate fusion may be satisfactory. Keywords: four-corner fusion, spider plate, long term follow-up, complications

What are the surgical methods used in the treatment of scaphoid fracture?

Methods The surgical technique undertaken was standard. That is, through a dorsal approach the scaphoid and tip of the radial styloid were excised. The capitate, lunate, triquetrum, and hamate articular surfaces were then prepared down to bleeding bone. Bone grafts from the scaphoid and radial styloid were then inserted and fixation undertaken.

Is four-corner fusion a reliable limited wrist fusion technique?

Conclusions: Four-corner fusion is a reliable limited wrist fusion technique that provides pain relief, grip strength and satisfactory range of motion in patients with degenerative conditions of the wrist. Partial union is more common with Kirschner wire fixation and complications are more common with circular plate fixation.
