Surgical treatment of trapeziometacarpal joint arthritis: a historical perspective.
BACKGROUND
The trapeziometacarpal (TMC) joint's unique anatomy and biomechanics render it susceptible to degeneration. For 60 years, treatment of the painful joint has been surgical when nonoperative modalities have failed. Dozens of different operations have been proposed, including total or subtotal resection of the trapezium or resection and implant arthroplasty. Proponents initially report high levels of patient satisfaction, but longer-term reports sometimes fail to support initial good results. To date, no one procedure has been shown to be superior to another.


OBJECTIVE
This review sought to identify factors responsible for the development of many different procedures to treat the same pathology and factors influencing whether procedures remain in the armamentarium or are abandoned.


METHODS
I performed a nonsystematic historical review of English-language surgical journals using the key words "carpometacarpal arthritis", or "trapeziometacarpal arthritis", and "surgery" in combination with "history" using the PubMed database. In addition, bibliographies of pertinent articles were reviewed.


RESULTS
The factors that led to many surgical innovations appear to be primarily theoretical concerns about the shortcomings of previously described procedures, especially about proximal migration of the thumb metacarpal after trapezial resection. Longevity of a particular procedure seems to be related to simplicity of design, especially for prosthetic arthroplasty. The evolution of surgery for TMC joint arthritis both parallels and diverges from that in other joints. For example, for most degenerated joints (even many in the hand), treatment evolved from resection arthroplasty to implant arthroplasty. In contrast, for the TMC joint, the 60-year-old procedure of trapezial resection continues to be performed by a majority of surgeons; many modifications of that procedure have been offered, but none have shown better pain reduction or increased function over the original procedure. In parallel, many differently designed prosthetic total or hemijoint arthroplasties have been proposed and performed, again with as yet unconvincing evidence that this technology improves results over those obtained by simple resection arthroplasty.


CONCLUSIONS
Many procedures have been described to treat TMC joint arthritis, from simple trapezial resection to complex soft tissue arthroplasty to prosthetic arthroplasty. In the absence of evidence for the superiority of any one procedure, surgeons should consider using established procedures rather than adopting novel ones, though novel procedures can and should be tested in properly designed clinical trials. Tissue-engineered solutions are an important area of current research but have not yet reached the clinical trial stage.
