Background:
Wrist arthroplasties have been used for dekades with better re-
sults for the newer designs.
Purpose / Aim of Study:
The aim of this study is was to review our short-
term results of the Maestro prosthesis used for primary and revision wrist- ar-
throplasty.
Materials and Methods:
The Maestro implant is a modular total wrist joint
prosthesis. The indications for it´s use in this study were rheumatoid arthritis
(RA), degenerative (OA) and posttraumatic arthritis (POA) and revision of for-
mer Wrist arthroplasty. The procedure was performed in 14 patients, 3 men and
11 women. Median age was 64 years (41-75). 10 RA, 3 OA and 1 POA pa-
tients were operated. Median follow-up was 13 month (range 12-25). Primary
arthroplasty was performed in 11 patients and revision arthroplasty in 3 (2
KMI - and 1 Remotion prosthesis were removed). Cement was used in 4 cases.
Additional Darrach procedures were performed in 4 cases.
Findings / Results:
Wrist extension and flexion was preoperatively 35/30 de-
grees and at follow-up 40/25. Radial/ulnar deviation was 10/30 degrees ver-
sus 10/25 postoperatively. Grip strength, in KgF, was preoperatively 8 (range
2-36) and at follow-up 18 (7-30). VAS pain (0-100 mm) was preoperatively
at rest/activity; 30/65 mm and at follow-up; 2/4 mm. Minor radiographic os-
teolysis around one screw was seen in 2 of 14 cases at the last follow-up, but
no signs of loosening were detected. Quick DASH and PRWE were preopera-
tively; 50 and 68 and at follow-up; 28 and 12. VAS satisfaction at latest follow-
up was 98 mm (34-100).2 minor hematomas and 1 moderate hematoma were
observed. No infections, dislocations or other early complications were encoun-
tered and no reoperations performed.
Conclusions:
In this small selected case series the Maestro Total Wrist
Arthroplasty had a low complication rate and showed promising short-term re-
sults.
