Clinical results of shoulder arthroplasty with the UNIVERS 3-D prosthesis in treatment of post-traumatic gleno-humeral arthritis / 中华创伤杂志

Objective To evaluate clinical results of arthroplasty with the UNIVERS 3-D shoulder prosthesis in post-traumatic gleno-humeral arthritis. Methods A total of 54 cases (age range of 31-84 years, mean 67.07 years) with post-traumatic gleno-humeral arthritis were treated by the arthroplasty with the UNIVERS 3-D prosthesis. Constant score and normalised Constant score were used to strictly evaluate the preoperative function of 45 cases, of which 30 cases were reviewed by Constant score and normalised Constant score postoperatively with an average follow-up of 12-68 months. Of all, 44 cases were strictly followed up in respect of preoperative and postoperative X-ray including anteroposterior, axial and Y-shaped positions. Results Compared with the pre-operation, there was a significant increase in post-operative pain, activity, mobility and strength as well as the postoperative Constant score and normalized Constant score. Total shoulder arthroplasty (TSA) provided better score for daily life and mobility than hemiarthroplasty, with a significant difference (P

Objective To evaluate the clinical results of arthroplasty with the UNIVERS 3 D prosthesis in shoulder rheumatoid arthritis (RA). Methods Six cases of shoulder RA underwent the arthroplasty with the UNIVERS 3 D prosthesis. Five cases were strictly reviewed by Constant score and normalized Constant score after operation with an average follow up of 26 months, ranging from 12 to 45 months. Five cases were reviewed by the radiological analysis on preoperative and postoperative X ray including three AP views, scapular view, and axillary view. The radiographic forms were classified by two different criteria according to Levigne. Results The postoperative Constant score (mean, 55.06) and normalized Constant score (mean, 72.2%) were improved more than one time in all cases except one. Complication of anterior superior subluxation occurred in glenohumeral joint of one case and no surgical treatment performed. The radiographic forms were classified by Levigne on humeral head wear (including 2 cases of microgeodes, 1 case for notch in the greater tuberosity, and 3 cases for spherical form loss) and on the sphericity and upward migration of the humeral head (1 case for ascending form, 1 case for centered form, and 4 cases for destructive form) according to the clinical results. Conclusion The arthroplasty with the UNIVERS 3 D prosthesis results with excellent clinical function results in shoulder RA without any radiolucent line and with very low complication. Radiological classification on the sphericity and upward migration of the humeral head, and humeral head wear may be useful element in operation choice and its prognosis.
