Abstract
대퇴골에 삽입되는 스템(1)을 갖는 고관절 내장 보철물은 보철물의 상단부에서 넥 베어링(4 ; neck bearing)에 일체로 연결되어 있고, 종방향 홈(5)을 가지고 있다. 후속 수술시, 종방향 홈이 기부(基部) 방향에서 접근이 가능하도록 하기 위해, 넥 베어링(4)은 종방향 홈의 영역에 컷아웃(cutouts)을 갖추고 있다. 넥 베어링은 컷아웃(6)을 폐쇄하는 제거 가능한 부착물(attachment)을 갖추고 있다.
Description
본 발명은 대퇴골에 삽입되고, 상단부에서 넥 베어링과 일체로 연결되고, 종방향 홈을 갖는 스템을 구비한 고관절 보철물에 관한 것이다.
스템에 있는 종방향 홈은 보철물에서 주변의 뼈로의 힘 전달을 향상시킨다. 이는 접착제(cement)의 사용없이 이식한 경우 특히 중요하다. 이 경우, 뼈 조직은 치료 중에 홈 사이로 성장하여, 다소 견고히 보철물의 표면과 연결된다. 그러나, 홈을 갖는 보철물 스템을 장착하는 것은 접착제를 사용한 이식의 경우에 있어서도 용이할 수 있다. 만일, 후속 수술 중에, 홈에 있는 뼈 또는 접착제의 재료가 다시 제거되려면, 시술자는 적절한 끌(chisel)을 기부 방향으로부터 홈 내로 진입시켜야 한다. 상기 서술에 대한 선결 조건은 홈이 기부 말단으로부터 접근이 용이해야 한다는 것이다.
기존의 대퇴골의 고관절 보철물(유럽 특허공보 제93378호의 도1 및 도2 참조)은 스템과 일체로 설계된 넥 베어링을 가지고 있다. 스템은 종방향 리브(rib)를 구비하며, 상기 리브 사이에 깊은 홈이 형성된다. 상단부에서, 리브와 홈은 넥 베어링까지 연장되고, 상기 넥 베어링에 의해 한계가 정해진다. 넥 베어링이 고관절의 방향으로부터 홈의 공간을 폐쇄하고 있으므로, 상기 공간은 후속 수술 중에 접근하기 어렵다. 그러므로, 보철물이 이식된 상태로 부착물을 제거하는 것이(상기 유럽 특허공보의 도5에) 제안되었으나, 보철물의 연결 특성은 자세히 나타내지 않았다. 유사한 보철물[발데마르 링크사(Waldemar Link GmbH & Co)에서 발행한 책자 : "링크 리브 시스템(Link Rippen-system, Link Rib System)에 개시됨]에 있어서, 편자 모양의 넥 베어링의 암(arm)들은 스템 전후의 안내 홈에 유지된다. 넥 베어링이 제거될 때, 수술시 접근을 방해하는 상기 홈의 영역에 존재하는 어떠한 돌출부도 없다. 그러나, 스템의 종방향을 가로질러 연장된 안내 홈은 많은 경우 스템의 단면적을 감소시켜서 강도가 낮아지기 때문에 바람직하지 않다. 더욱이, 넥 베어링의 신뢰성에 관해서는, 많은 의사들이 스템에 일체로 연결되는 넥 베어링을 선호한다.
홈을 갖는 스템의 전후 측면은 넥 베어링을 구비하지 않고 상기 보철물 스템의 홈이 없는 중간의 폭이 좁은 측면에만 넥 베어링과 같은 작은 돌출부를 제공함으로써 이러한 문제를 회피한 대퇴골 고관절 보철물(프랑스 특허공보 제2 595 241호)이 공지되어 있다. 그러나, 넥 베어링에 의한 뼈의 특정 장착 하중을 최소화하기 위해 넓은 면적을 갖는 넥 베어링을 만들려고 시도해 왔었다. 그러므로, 넥 베어링이 홈을 갖는 스템의 측면들에도 존재하는 것이 본 발명의 요건이다.
본 발명은 스템에 일체로 연결된 넥 베어링이 있어도 접근이 용이한 홈의 공간을 갖는 고관절 보철물을 이용하려는 것이다. 해결책으로는, 넥 베어링이 홈의 영역에 컷아웃을 구비하고, 상기 종방향 홈이 넥 베어링 위쪽에서 종료한다는 것이다. 다시 말해서, 종방향 홈은 넥 베어링의 영역까지 계속되고, 상기 넥 베어링을 절단하여 홈이 형성된다. 그러므로, 후속 수술 중 홈 영역에 있는 뼈의 연결 부위를 제거시키는 기구를 홈 내로 진입시키거나, 또는 이식 중에 뼈 재료로 상기 홈을 채우기(packing) 위해 홈의 공간을 이용할 수 있다. 그럼에도 불구하고, 보철물은 스템에 일체로 연결된 넥 베어링을 갖는다. 많은 경우에 있어서, 넥 베어링에 의해 컷아웃 외부에 주어진 표면은 하중을 지지하기에 충분하다. 만일 더 넓은 지지 면적이 필요하다면, 본 발명에 의해 기본적으로 종방향 홈의 영역에 있는 컷아웃을 폐쇄하는 제거 가능한 부착물을 이용하는 것이 가능하다. 넥 베어링 및/또는 스템은 보철물이 이식된 상태로 넥 베어링의 길이 방향(course)에 평행하고, 부착물이 삽입 또는 제거되는 방향을 따라 연장된 활주 안내부를 형성한다.
본 발명은 효과적인 도식적 실시예를 도시하는 도면들을 참조하여 이하에 상세히 설명하였다.
대퇴골에 삽입되는 보철물 스템(1)은 상단부에서 관절 헤드를 배치하는 콘(3)을 지지하는 넥(2)으로 합체된다. 스템 또는 넥의 모든 측면 또는 적어도 전후 측면에 측방으로 돌출되고, 뼈의 절개 표면을 지지하기 위한 평평한 바닥 면을 가지고 있는 넥 베어링(4)이 스템(1)과 넥(2) 사이에 있다.
스템(1)은 상기 스템의 중심선에 평행하게 연장된 홈(5)을 전후 측면에 각각 2개씩 가지고 있다. 알려진 바와 같이, 이러한 홈(5)은 보철물의 표면과 주위의 뼈 재료 사이에 보다 확실한 결합을 위해 사용되는데, 뼈 재료는 보철물 스템을 끼우기 위한 공동(cavity)을 만들 때 상기 영역에 남아있거나, 또는 보철물 스템으로 대체 될때 상기 영역에 이르거나, 또는 패킹 작업(packing)에 의해 이 영역에 채워지거나, 또는 계속하여 성장한다. 스템과 홈의 단면은 도6에서, 즉 이들 외형 윤곽선으로 도시된다.
이식 중 뼈의 재료를 채워 넣고, 또는 제거 중에 뼈와 보철물 표면 사이의 결합을 해제하기 위해 홈의 단면이 접근 가능하게 되는 것을 보장하기 위하여 넥 베어링(4)은 도4에 도시된 바와 같이 상기 홈의 각각의 영역에 컷아웃(6)을 갖추고 있다. 그럼에도 불구하고, 경우에 따라 예컨대 절개 표면을 지지하기에 충분한 실제 표면이 남아있는 것을 볼 수 있다.
만일 넥 베어링(4)의 나머지 표면이 충분하지 않다면, 부착물(7)이 추가된다. 상기 편자 모양의 부착물은 그 내부(8)에 인접하는 평행한 안내 에지(9 ; edge)를 갖는다. 전후 측면에서, 보철물 스템(1)의 상단부에 위치한 넥 베어링(4) 아래의 수납 홈(10)의 각각은 상기 에지(9)에 대응된다. 부착물(7)이 도1에 표시된 화살표 방향으로 스템에 삽입될 때, 상기 안내 에지(9)는 홈(10)에 의하여 수용되어 고정된다. 부착물은 나사(11)에 의해 그 자리에 고정된다. 도5에 도시된 바와 같이, 부착물(7)은 전후 및 중간 영역의 지지 표면을 확장할 뿐만 아니라 넓은 범위까지 컷아웃(6)을 폐쇄한다. 상기 지지 작용이 피질의 외부 뼈 영역에서 주로 발생하므로, 스템의 중심 부근까지 컷아웃을 완전히 폐쇄하는 것이 꼭 필요하지는 않다.
스템과 일체로 설계된 부분(4)이 넥 베어링으로 언급된다는 것은 상기 넥 지지 기능을 혼자, 즉 부착물(7) 없이도 수행할 수 있어야 하는 것을 의미하려는 것은 아니다. 대신에, 넥 베어링으로 언급된 상기 부분은 부착물을 고정하는 기능으로 제한될 수 있으므로 둘 모두가 넥 베어링을 형성한다.
도1에 도시된 바와 같이, 홈(5)은 넥 베어링(4) 바로 위까지 완만하게 연결되어서 끝난다. 또한, 이는 수술 기구의 사용을 보다 쉽게 한다. 그러나, 넥 베어링(4)의 영역에서만 또는 그 바로 아래 영역에서 상기 홈이 시작되게 하는 것도 고려될 수 있다.
본 발명에 의하면 넥 베어링을 통과하여 형성된 종방향 홈 내에 컷아웃이 형성되어 있으므로, 상기 컷아웃 및 홈을 통해 수술 도구를 용이하게 진입시킬 수 있으며, 이식 시에는 뼈 재료를 채우는 공간으로 용이하게 사용될 수 있다. 또한 제거 가능한 부착물을 넥 베어링에 삽입할 수 있으므로 하중 지지 성능 또한 향상 될 수 있다.
도1은 보철물의 측면도로서, 보철물에 삽입된 부착물을 단면 형태로 도시한도면.
도2는 보철물에 삽입된 부착물의 평면도.
도3은 보철물의 다른 측면도.
도4는 도1의 선 IV에서 본 단면도.
도5는 부착물이 삽입된 도4에 대응되는 단면도.
도6은 도1의 선 VI에서 본 단면도.
