[Comparison of the Results of Lundborg's and Sirotakova's Resection-Suspension Arthroplasty for the Treatment of Trapeziometacarpal Joint Osteoarthritis].
OBJECTIVE
The aim of this prospective randomised study was to compare Sirotakova's and Lundborg's methods of resection-suspension arthroplasty using the abductor pollicis longus tendon in the surgical treatment of osteoarthritis of the trapeziometacarpal joint.


METHODS
Between 2009 and 2012, 38 patients (29 female, 9 male) with symptomatic trapeziometacarpal osteoarthritis (34% stage II, 58% stage III and 8% stage IV according to the Eaton-Littler classification) were randomly allocated to one of the surgical methods (mean age 62.7 years, range 43-85). Preoperatively, the following data were collected: pain intensity (Visual Analogue Scale, VAS; at rest: Lundborg 4.4±1.7; Sirotakova 4.6±2.1), strength (key pinch force Lundborg 8.1 kPa±6.6; Sirotakova 10.4 kPa±10.8), range of motion in the trapeziometacarpal joint (Lundborg 61.64±26.4; Sirotakova 46.67±25.6), Kapandji index (Lundborg 9.42±1.4; Sirotakova 9.33±1.5), distance between the base of the first metacarpal bone and the scaphoid bone as measured by standardised x-ray images (Lundborg 12 mm±1.5; Sirotakova 11.4 mm±3), DASH questionnaire (Lundborg 40.4±13.9; Sirotakova 49.9±23.5). A significant difference between the 2 groups was not found. Patients were examined 3 and 9 months postoperatively.


RESULTS
Both resection-suspension arthroplasty procedures led to a statistically significant postoperative reduction of pain, a significant improvement in radial and palmar abduction, a significant gain in quality of life and significant asymptomatic proximalisation of the first metacarpal bone. There was no significant difference in postoperative strength.


CONCLUSIONS
Both methods lead to reliable and satisfying results. Given our findings we cannot generally recommend one method over the other.
