Randomized Controlled Trial Comparative Study[Resection, interposition and suspension arthroplasty for treatment of Basal joint arthritis of the thumb: a randomized and prospective comparison of techniques using the abductor pollicis longus- and the flexor carpi radialis tendon].
The operative treatment of thumb carpometacarpal joint arthritis may include resection-suspension-interposition-arthroplasty. Although quite a technically demanding procedure, a suspension arthroplasty using a strip of the flexor carpi radialis tendon is quite a popular technique. Other techniques, which use the abductor pollicis longus (APL) tendon, is also widely accepted. ⋯ After 8 months both groups had comparable subjective results (APL-group: VAS 2.3 points, DASH 24 points; FCR-group: VAS 1.9 points, DASH 20 points) as well as functional results (APL-group: radial abduction 55.3°, key-grip strength 8.1 kg, pinch-grip strength 5.5 kg; FCR-group: radial abduction 55.8°, key-grip strength 7.2 kg, pinch-grip strength 4.7 kg). Radiologically both groups showed an approximate 50% reduction in the height of the trapezial space. In resection-suspension-interposition-arthroplasty of the 1st CMC joint, similar results can be obtained using the technically less demanding APL-procedure when compared with the FCR-technique 8 months postoperatively.
