Outcome of Copeland shoulder resurfacing arthroplasty with a 4-year mean follow-up

Mid-term results of Copeland shoulder cementless surface replacement arthroplasty from an independent centre

“…1 The occurence of glenoid erosion following Copeland shoulder resurfacing arthroplasty according to glenoid drilling. which is unique to their series [11]. They also highlighted that the better results were in patients with OA and AVN, with poorer outcomes in RA and RCA, in keeping with the findings of Levy et al [1].…”

“…A comparison between the present study and the literature from both the designer's institution and independent centres is presented in Table 3. The OSS has only been used in more recent studies [10][11][12], with older studies using the Constant score (CS) [14]. Levy (2) MUA, manipulation under anesthesia; TSR, total shoulder replacement.…”

“…Although limited in numbers and follow-up, studies from independent centres have demonstrated that the functional results appear to be reproducible [8][9][10][11]. However, higher rates of glenoid erosion than those seen in the designer's institution have been reported [9][10][11]. Although this has not resulted in revision surgery in all cases, it remains a cause for concern regarding the possible increase in requirement for revision surgery in the future with longer follow-up and the available glenoid bone stock for these procedures.…”

Resurfacing of the humeral head: An analysis of the bone stock and osseous integration under the implant

“…The unloaded bone is then resorbed and has been described as femoral neck narrowing which is observed for a high percentage of the HRAs . Similarly, for CRSA osteolysis around the prosthetic rim has been described . As some of the implants showed no progression, but some required revision, the functional and clinical impact of osteolysis in CRSA is unknown.…”

“…Advantages of humeral head resurfacing include minimal bone resection, a short operative time, low prevalence of humeral periprosthetic fractures, maintenance of native inclination, offset, head-shaft angle and version of the humerus [11], and an ease of revision to a conventional total shoulder replacement, if needed and ability to implant in deformed shaft. Outcomes of various surface replacement arthroplasty designs have been comparable with those of arthroplasties with a stemmed prosthesis in numerous short and mid-term follow-up studies [12,13].…”
