Abstract

BACKGROUND

There are concerns regarding glenoid erosion with metal shoulder hemiarthroplasty. PyroCarbon may offer an alternative because of favorable wear characteristics and preservation of the glenoid. The purpose of this study was to assess in vitro bone wear characteristics of PyroCarbon relative to cobalt chromium alloy hemiarthroplasty in a shoulder wear simulator.

METHODS

Wear of PyroCarbon and cobalt chromium prostheses articulating with bone were characterized by means of bone wear penetration rate, changes to surface roughness, and wear particle analysis.

RESULTS

PyroCarbon prostheses produced significantly less damage to bone and were less damaged by the bone than cobalt chromium prostheses. Cobalt chromium testing was halted at approximately 320,000 cycles because the bone was consumed. Wear testing of PyroCarbon specimens continued through five million cycles. Linearized bone penetration rate, bone volume loss rate, and surface roughness for cobalt chromium test specimens were 30 times greater than for PyroCarbon.

CONCLUSIONS

Results demonstrate significantly less damage to bone in simulated shoulder function testing for PyroCarbon hemiarthroplasty implants relative to conventional cobalt chromium implants. Our study supports use of PyroCarbon in humeral head hemiarthroplasty as a viable alternative to conventional metal hemiarthroplasty. Further investigation of PyroCarbon performance in clinical settings is warranted.

摘要

背景

金属半肩关节置换术存在肩胛盂磨损的问题。由于具有良好的磨损特性以及对肩胛盂的保护作用，热解碳可能提供一种替代方案。本研究的目的是在肩部磨损模拟器中评估热解碳相对于钴铬合金半关节置换术的体外骨磨损特性。

方法

通过骨磨损穿透率、表面粗糙度变化和磨损颗粒分析来表征热解碳和与骨关节连接的钴铬假体的磨损情况。

结果

热解碳假体对骨的损伤明显小于钴铬假体，且热解碳假体被骨损伤的程度也更小。钴铬合金的测试在大约320,000次循环时停止，因为骨已被消耗殆尽。热解碳标本的磨损测试持续进行了500万次循环。钴铬测试标本的线性化骨穿透率、骨体积损失率和表面粗糙度比热解碳大30倍。

结论

结果表明，在模拟肩部功能测试中，相对于传统的钴铬植入物，热解碳半关节置换植入物对骨的损伤明显更小。我们的研究支持在肱骨头半关节置换术中使用热解碳作为传统金属半关节置换术的可行替代方案。有必要对热解碳在临床环境中的性能进行进一步研究。
