Comparing different immobilization durations after thumb joint surgery

Variable Immobilization Protocol for Arthroplasty of the Carpometacarpal Joint of the Thumb

Not applicable Interventional University of Chicago · NCT04828954

This study tests whether keeping the thumb in a cast for 2 weeks or 6 weeks after surgery helps people with thumb arthritis heal better and recover faster.

What this trial studies

This clinical trial investigates the optimal duration of postoperative immobilization for patients undergoing arthroplasty of the carpometacarpal joint of the thumb due to osteoarthritis. Participants will be randomly assigned to receive either a 2-week or a 6-week immobilization protocol using a non-removable thumb spica plaster splint. The study aims to balance the benefits of immobilization for healing and pain control against the risks of stiffness and delayed recovery. By establishing an evidence-based rehabilitation protocol, the findings could enhance postoperative care for patients undergoing this common surgical procedure.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 40 and older who are scheduled for arthroplasty of the first carpometacarpal joint.

Not a fit: Patients under 40 years of age or those with prior thumb surgeries or specific inflammatory conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery protocols that enhance patient outcomes and reduce complications after thumb joint surgery.

How similar studies have performed: While there is limited high-level evidence on optimal immobilization durations, similar studies have explored postoperative care in hand surgery, indicating a need for further investigation.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age \>= 40 years old
* Patients undergoing arthroplasty of the first CMC joint including:

  1. Trapeziectomy with LRTI
  2. Simple Trapeziectomy
  3. Suspensionplasty (suture vs. APL)

Exclusion Criteria:

* Patients \< 40 years of age
* Patients who have undergone prior surgical procedures on the thumb base
* Patients with history of prior procedure at the base of thumb, or those with plan for concomitant carpal tunnel release or thumb metacarpophalangeal (MCP) arthrodesis, will be excluded. Concomitant carpal tunnel surgery may skew outcome surveys, and an arthrodesis procedure will warrant a longer length of immobilization following procedure.
* Those undergoing implant arthroplasty
* Patients with a diagnosis of inflammatory arthritis
* Patients with diagnosis of hypermobility syndrome
