Excision of the trapezium for osteoarthritis at the base of the thumb

Adverse effect of porcine collagen interposition after trapeziectomy: a comparative study

Twenty-six hands in 26 adults with osteoarthrosis of the thumb trapeziometacarpal joint were randomised to undergo either trapeziectomy alone (control) or with the interposition of porcine dermal collagen xenograft (Permacol). The study was terminated prematurely because of apparent reactions to the implants in six of 13 patients. The collagen interposition group required more frequent review on clinical grounds and were discharged later after surgery. Three of the implants have been removed and histology revealed foreign body reactions in all. There was no difference in thumb movement or power after surgery between the two groups. However, improved grip strength was observed and improved function were reported only in the control group. Permacol patients reported greater pain and were less satisfied with their operations than control patients. We conclude that interposition of Permacol is detrimental to the results of trapeziectomy.

Basal joint arthritis of the thumb

Thumb pain secondary to arthritis at the basal joint of the thumb is a common condition, especially in women, and can be quite disabling. An accurate diagnosis can be readily made from the history and examination. Radiographs are used to stage the severity of the arthritis. Splinting is the mainstay of conservative care. Reconstructive procedures for each stage of the disease are aimed at restoring thumb motion and strength. Partial or complete trapeziectomy with tendon interposition and ligament reconstruction to stabilize the metacarpal base is used for advanced disease. Secondary metacarpophalangeal joint hyper-extension deformity may need to be addressed. Surgery can reliably improve function and engender high patient satisfaction.

A comparison of trapeziectomy with and without ligament reconstruction and tendon interposition

Forty-three patients were randomly allocated to undergo either trapeziectomy alone (control) or with a ligament reconstruction and tendon interposition (LRTI) using an abductor pollicis longus tendon slip. The patients were reviewed at a median 13 (range, 7-29) months after surgery. The demographic characteristics, severity of disease and pre-operative clinical measurements of the two study groups were indistinguishable but LRTI lengthened the operation by approximately 15 minutes. Both groups expressed equal satisfaction with the operation and there were no significant differences between the two treatment groups. Simple trapeziectomy is an effective operation for osteoarthrosis at the base of the thumb and the addition of a ligament reconstruction was not shown to confer any additional benefit.

A patient-reported comparison of trapeziectomy with Swanson Silastic implant or sling ligament reconstruction

A retrospective review of two types of operations for carpometacarpal osteoarthritis of the thumb was done for patients operated on between 1991 and 1996. Follow-up ranged from 18 to 90 months (mean 62 months). Fifty-eight Swanson Silastic arthroplasties and 56 sling excision arthoplasties were reviewed. Eight patients with Swanson arthroplasties underwent removal of the implant. Eight patients in the sling excision group required further surgery. These patients were excluded from further analysis. Questionnaires about pain, general satisfaction and function were sent to the other patients and 87 responses were received (sling 45, implant 42). In the implant group significantly better results were obtained for pain at 1 year, carrying a milk bottle and taking a handbrake off a car, and overall function. We conclude that trapeziectomy combined with Swanson implant gives better results in the short term if there are no complications of the operation.

The early results of the Brunelli procedure for trapeziometacarpal instability

We report the results of Brunelli's abductor pollicis longus transfer for symptomatic instability of the trapeziometacarpal joint in 15 hands (14 patients) at a mean follow-up of 21 months. Patients were assessed subjectively, and objectively by an independent observer. All but one of the patients were very satisfied with the result of the operation, including the six patients who had significant degeneration of the carpometacarpal joint surface preoperatively. Four patients said they had no pain and the mean pain score overall on a visual analogue scale was 1.2 (out of a maximum of 10). Overall the outcome was rated good or excellent in 11 of the 15 thumbs.

Trapeziectomy alone, with tendon interposition or with ligament reconstruction?

This randomized prospective study compared the results of trapeziectomy alone, or combined with tendon interposition or ligament reconstruction in 76 women with basal thumb osteoarthritis. At 3 month and 1 year follow-up the results of the three procedures were indistinguishable in terms of pain relief, hand function and thumb strength. In the short term at least, tendon interposition and ligament reconstruction do not improve the results of trapeziectomy.

De la Caffinière thumb carpometacarpal replacements. 93 cases at 6 to 16 years follow-up

The results of 93 de la Caffinière thumb joint replacements in 71 patients were reviewed between 6 and 16 years. The survival rate was 89% at 16 years. Eleven thumb joints had failed requiring revision. The commonest reason for failure was aseptic loosening of the trapezial component. The failure rate was higher in men of working age than any other group, which possibly reflects the increased demands on the prosthesis of these patients. We support the use of this implant for degenerative osteoarthritis, but caution against its use in men under 65 years.

Excision of the trapezium for osteoarthritis of the trapeziometacarpal joint of the thumb

We assessed the results of 86 trapeziectomies in 83 patients. Simple excision of the trapezium was performed in 54 thumbs. This was combined with shortening of the abductor pollicis longus tendon in 14 thumbs and with soft-tissue interposition and/or ligamentous reconstruction in 17 thumbs. 88% of the patients were satisfied with the result, 76% had relief of pain and 74% had no functional disability. The subjective results achieved with the three different techniques were similar. Clinical assessment of 57 thumbs revealed no statistical difference in web span, thumb adduction-flexion, key pinch and grip strength between the three operative procedures, nor in comparison with the non-operated contralateral hand.

First carpometacarpal joint arthritis. A comparison of two arthroplasty techniques

Trapeziectomy followed by reconstruction of the intermetacarpal ligament using a small slip of extensor carpi radialis longus tendon and a wide slip of flexor carpi radialis for tendon interposition (group A) is compared with trapeziectomy followed by palmaris longus tendon interposition (group B). Group A included 11 hands in nine patients. Group B included eight hands in eight patients. Significant pain at the base of the thumb and 1st carpometacarpal joint degeneration were indications for surgery. Outcome was assessed by subjective questioning, objective clinical measurement and radiography. Group A appeared to have a slower recovery but later developed a stronger hand, better dynamic thumb function despite reduced movement and the resting trapezial space was better preserved. Calcification within the trapezial space correlated with better results but this took 3 years to occur. Patients in group B had greater relief of pain and were more consistently satisfied at an early stage.
