Thumb carpometacarpal (CMC) arthroplasty is a surgical procedure designed to relieve pain and restore function in the thumb’s basal joint, particularly for patients suffering from arthritis at the base of the thumb. For those in Nebraska and Iowa experiencing thumb pain, here’s what to know about CMC arthroplasty, recovery, and outcomes.
What is Thumb CMC Arthritis?
Thumb CMC arthritis affects the joint at the base of the thumb, where the thumb meets the wrist. The cartilage in this joint wears down over time, leading to:
- Pain and Swelling: Especially when gripping, pinching, or holding objects.
- Weakness: Reduced ability to grip or perform fine motor tasks.
- Deformity: Visible changes in the thumb’s shape or alignment.
When is CMC Arthroplasty Recommended?
CMC arthroplasty is often recommended when:
- Non-Surgical Treatments Fail: Splinting, anti-inflammatory medications, or injections do not provide sufficient relief.
- Severe Pain and Functional Impairment: Daily activities are limited due to pain or weakness.
- Arthritis Progression: X-rays confirm advanced arthritis or joint degeneration.
Thumb CMC Arthroplasty
This advanced surgical technique not only replaces the damaged joint but also uses an suture and anchor suspension system for added support. The procedure is typically done on an outpatient basis.
- Joint Resurfacing or Replacement: The surgeon removes the arthritic bone.
- Suture and Anchor Placement: A specialized suture and anchor construct is anchored to stabilize the thumb joint, reinforcing its structure without needing additional ligament reconstruction. This helps improve stability and allows for a faster return to activities.
- Closure and Splinting: The incision is closed, and a splint is applied to protect the thumb during initial recovery.
Preparing for CMC Arthroplasty in Nebraska and Iowa
To prepare for thumb CMC arthroplasty:
- Consultation: Your surgeon will assess the severity of arthritis and confirm that you’re a candidate for the procedure.
- Pre-Surgery Instructions: Follow any fasting guidelines, medication adjustments, and make arrangements for assistance, as hand movement will be restricted after surgery.
- Home Setup: Create a recovery space with items within reach to minimize the need for hand use during recovery.
Recovery After CMC Arthroplasty
Recovery includes a combination of rest, pain management, and hand therapy:
- Pain Management: Prescription pain medications may be used initially, along with ice and elevation.
- Splinting and Protection: A splint is typically worn for the first few weeks to protect the joint.
- Hand Therapy: After the initial healing period, hand therapy focuses on regaining range of motion and building strength.
Recovery Timeline
- First 2-4 Weeks: Focus on resting the hand and keeping it elevated. Limited hand use with the splint.
- 4-8 Weeks: Gradual increase in hand therapy exercises to restore movement.
- 3-6 Months: Most patients regain strength and can return to normal activities, with full recovery possible by six months.
Long-Term Outcomes
Thumb CMC arthroplasty provides long-lasting pain relief, improved stability, and increased strength in the thumb joint.
