Proximal Row Carpectomy Recovery
Proximal Row Carpectomy
What the operation does
The wrist contains eight small bones in two rows. This operation removes the entire first row — the scaphoid, lunate and triquetrum — and lets the head of the capitate, the bone behind them, sit into the socket of the forearm bone. The wrist then hinges on that new arrangement. Nothing is fused and no metal is used.
Why removing bones works
It sounds drastic and it is elegantly simple. The worn surfaces are taken away entirely, and the rounded head of the capitate happens to fit reasonably well into the hollow of the radius where the lunate used to sit. The wrist becomes shorter and a little looser, and it moves. There is no fusion to heal, which is why this recovery is the quickest of the wrist salvage operations.
Why the wrist wore out
Almost always an old scapholunate ligament tear or a scaphoid fracture that never healed, either of which lets the wrist collapse and wear in a predictable pattern over years. By the time it is painful enough for surgery, the damage is usually well established.
The capitate head has to be healthy
The single condition for this operation. The head of the capitate becomes the new joint surface, so if it is already worn — or if the hollow in the radius it sits into is damaged — the operation cannot be done and a four-corner fusion is used instead. Your surgeon assessed that beforehand, and occasionally the final decision is made during the operation once the joint is seen.
How it compares with a four-corner fusion
They give broadly similar movement, and the trade is elsewhere. This one is simpler, quicker to recover from, uses no hardware, and has nothing that can fail to unite. The fusion generally gives somewhat better grip strength and can be done in wrists where the capitate is already worn. Neither is clearly better; they suit different wrists and different demands.
How much movement you keep
Usually somewhere around half to two thirds of normal, which is more than enough for most daily tasks. Turning the palm up and down is unaffected, because that happens at the forearm rather than the wrist.
Grip strength
Typically returns to around two thirds of the other side, and often a little less than after a four-corner fusion — because removing a row of bones shortens the wrist slightly and the tendons work at a small mechanical disadvantage. It improves over a year. If heavy gripping is central to your work, that difference is worth discussing.
Pain relief is the point
This is done for pain rather than for movement, and it is reliable for that. Most people get substantial relief of the arthritic ache they came with. Some discomfort with heavy or prolonged use commonly remains and is expected rather than a failure.
How long it lasts
The honest limitation. The capitate head is not designed to be a joint surface, and over the years it can wear against the radius — more quickly in younger, heavier-using wrists. Results are generally good for many years, and in a younger manual worker a four-corner fusion or eventually a full fusion may be the more durable plan. Age and demand drive that choice more than anything.
The cast and the early weeks
A cast or firm splint for around two to three weeks, considerably shorter than after a fusion because there is nothing to unite. During that time the fingers, thumb and elbow must keep moving — a stiff hand is the avoidable complication.
Nerve at the back of the wrist
Many surgeons divide a small nerve branch on the back of the wrist during this operation, deliberately, because it carries pain sensation from the joint. It leaves a small numb patch and generally reduces pain. If you noticed numbness on the back of the wrist afterwards, that is likely why.
If it wears out later
Converting to a total wrist fusion is straightforward and effective, and having had this operation does not make it harder. Knowing that path exists makes the durability question easier to hold — this is a step that keeps options rather than closing them.
Driving and work
Driving generally waits until you are out of the cast and can grip and turn the wheel confidently — commonly around four to six weeks. Desk-based work is often possible within one to two weeks. Manual work involving gripping commonly waits three to four months.
How the first year usually unfolds
Three weeks in a cast with fingers, thumb and elbow kept moving. Three to eight weeks brings wrist movement back, and it returns faster than after a fusion. Two to five months brings grip and wrist strengthening. Five to twelve months settles the final strength and comfort, both of which continue improving.
Staying in touch with your care team
How worn the wrist was, and the state of the capitate head, shape what to expect. Your surgeon saw both. If something about your recovery is worrying you or does not match what is described here, contact your care team — they would far rather hear from you.
