Materials and Methods: rom march 1996 to July 2002, five cases in six patients whose metatarsal head collapse already progressed underwent operative treatment. We compared the operative results in the view point of the radiographic follow-up and lesser toe metatrasophalangeal joint scale of AOAS. Results: There were no further joint destruction and loose body formation. Also, lesser toe metatrasophalangeal joint scale of AOAS improved from average score, 38.5 (range 22~49) of preoperative one to average score, 86.6 (range, 72~100). Especially, the 2 cases that underwent dorsal closing wedge osteotomy showed most favorable result and the 2 cases with metatarsal resection showed next favorable result. The 2 cases with intra-articular loose body removal and metatarsal reshaping showed the least effective result among three operative methods. Conclusion: Our Operative experiences of old neglected reiberg's disease were all satisfactory irrespective of operative options and dorsal closing wedge osteotomy was thought to be most effective method.

Breck 8) 은 1000 예의골연골증분석보고에서 80% 가하지에집중적으로발생한다는것으로보아외상과반복적인외력이작용할것으로보고하였고, Braddock 9) 은사체연구를통한실험적인연구에서제2중족골골단은 11세에서 12.5세사이의발달기에가장손상받기쉬우며, 또한가동성이적은구조적인문제도관련인자로보고하였다. 많은다른저자들은굽이높은구두나스포츠활동에의한압박이나반복적인외상, 상대적으로긴중족골두로인해골두배측골소주의외상성손상 (dorsal trabecular stress injury) 을받아항상중족골두의전측과배측 (anterior and dorsum) 에병변이발생한다는점을들어외상에의한병인을보고하였다 10~12). reiberg 병의발병원인으로중족골두에공급되는혈류의장애역시많은보고가있었으며 12,13,), 중족골두의선천적인혈액공급의이상이나혈관의손상, 지방색전증, 과응고상태, 골수강내의압력상승등이관련인자로거론되었다 14,15). 아직까지도정확한병인에대하여정의되지는않았지만최근에는단일병인에의한발생보다는전술한다양한요인들의상호작용으로인한다인자성병인론이우세를차지하고있다 16~18). reiberg 병의병태생리에대한연구는 Smillie 2) 가 5가지의병리단계 (pathologic staging) 를방사선학적인소견과연관하여분류하였으며 Gauthier 와 Elbaz 6) 는해부학적인진행과정을바탕으로한 5단계의진행을보고하였고, Omer 19) 는 reiberg 병을포함한모든골연골증의병태생리를조직학적인변화와진행을근거로한 3단계로분류하였다. 본논문에서는방사선학적인소견을근거로한 Smillie 의 staging을사용하여 stage III 1예, stage IV 2예, stage V 3예의전체 6예, 5명의환자를대상으로하였다. 치료원칙은다른질환에서와마찬가지로병의진행이초기일때는보존적치료를먼저시행하고보존적치료의결과가만족스럽지않을때수술적치료를한다. 보존적치료의목적은발병원인인자를최소화하여중족골골단이나관절의변형 (epiphyseal or articular deformity) 을적게하고통증을줄이는데있다. 보존적치료는질병의초기에사용하였을때효과있는것으로보고되고있고 10), Hoskinson 20) 은전체 28명의환자에서보존적요법으로만치료한 16명중 11명이최종추시상증상의완화와동통의소실을보고하였지만, Sproul 21) 은보존적치료를한대부분의환자에서지속되는통증으로수술이필요했다고보고하였다. 질병의진행이심하지않은환자에대하여보존적인처치를통한통증소실을확인하였으나, 본 6예의환자들은 Smillie staging III 이상으로전예에서동통이심하였고, 중족족지관절의운동범위가현저하게감소되어있었으며, 일부에서는중족골두의변형과관절염변화가시작된상태로모두수술적인처치를시행하였다. 수술적치료의목적은중족골두주변의유리체, 가골 (osteophytes) 로인해족저부혹은배부에발생한과각화증 (hyperkeratosis) 이나골극 (bone spur) 으로신발을신을때나보행시발생하는통증을제거하기위해비후된활액막제거, 중족골두나근위지골절제, 파괴된관절면의제거혹은남아있는정상관절면을이용해기능을할수있는관절면으로전환시켜통증을제거하고관절의기능회복시키는것이다. 수술적치료의종류는이환된중족골두나근위지골기저부절제술 20,22), 중족골두배부의함몰된관절면의해면골이식술 2), 중족족지관절의 K-강선을이용한관절고정술 23), 중족골두배굴절골술 6), 관절재형성술 5), 중족골단축술, 인공관절대치술, silicon spacer 를이용한인공물삽입관절성형술 6,24) 등으로다양하며, 이들각술기에대한정확한적응기준은아직명확하지않다. 절제술은많은저자들에의하여만족스런결과가보고되었지만 1,2,19), 진행성무지외반증, 족지단축, 전이성중족골동통 (transfer metatarsalgia) 을야기시키고, 최근의많은학자들은심각한중족골아치 (alignment of the metatarsal arch) 의소실을초래하여족지의변형과보행의불균형을일으킨다고보고하였다 13,17). 그러나최근에도아주진행된 reiberg 병에한해서는중족골두절제술을시행할것을주장하는보고도있다 18,23). 저자들이중족골두절제술을시행한 2예의진행된 smillie staging IV, V의환자에서평균 6.2 년의추시상중족골아치의변형이나제2 족지의단축은없었으며보행시동통도호전을보여변형이진행된후기의환자에게간단하게사용할수있는술식으로사료된다. reiberg 병에대해사용할수있는또다른술식으로 silicon spacer를이용한인공관절성형술이있으나, 감염이나, 활액막염, 삽입물의파손, 전이성중족골동통의잠재적위험을안고있어사용에제약이따른다 6,23,25). 관절내유리체제거술및중족골두재형성술은 Mann 5) 에의하여시행된중족골의길이와기능을그대로유지하면서관절내파괴된연골부위의절제와유리체를제거하는술식으로많은보고에서좋은결과를나타내고있으나 5,6,11,26), 저자들의경우에는비교적효과적인술식으로는생각되나이환된중족족지관절의운동제한이남았으며, 손상된관절연골을그대로남겨둠으로써조기퇴행성변화의가능성을배제할수없는문제점이있었고, 1예에서는 6년 3개월간의추시에도지속적인동통이남아다른술식에비하여양호하지못한 - 146 -
소견을보였다. 이러한지속적인동통의원인은손상된관절연골부가관절운동시접촉되면서통증이발생한것으로생각된다. 중족골두배굴절골술은 Gauthier 와 Elbaz 6) 가보고한술식으로발생부위가중족골두의배측에국한되고관절면의족저부는거의보존된다는점에착안하여이환된배측병소부위를절제하고정상인족저부관절면을절골술로배굴시켜새로운관절면을만드는방법으로 53예중 1예를제외하고는모두만족할만한결과를얻었다고보고했다. 술기가비교적간단하며, 철사만으로견고한고정을얻을수있어조기체중부하가가능하고, 골유합이쉽게이루어지며, 중족골자체의단축 (shortening) 과거상 (elevation) 에의한감압효과까지있어동통제거의장점이있다 17,27,28). 하지만보고에따라절골술로만들어진관절면이정상의관절면과완전히일치하지못하고, 족저부의피질골을유지하면서폐쇄절골을하여야하는기술적인문제와원위골편의무혈성괴사의위험성, 고정용철사에의한건염 (tendinitis) 의발생 27), 골유합이후의철사제거를위한재수술등이단점으로지적되었다 26). 저자들은중족골두배굴절골술을통한 2예의평균 5년추시에서술식이비교적간단하고, 쉽게골유합을얻었으며, 관절운동범위의회복이다른 2가지의술식에비해가장좋았다. 또한, 보행시동통의소실과방사선학적으로관절면의일치성을얻을수있었고, 환자의만족도도 3가지술식중가장높은것으로나타났다. 결론저자들은 1996년 3월부터 2002년 7월까지총 6예, 5명의간과성 reiberg 병환자에대하여중족골두절제술, 관절재형성술그리고중족골두배굴절골술을각각 2예씩시행하였으며평균 5.3년간의추시하여다음과같은결과를얻었다. 1. 전례에서모두여자였으며, 모두제2 중족골두가이환되었다. 2. 3가지다른술식을이용한모든환자에서증상의호전과양호이상의결과 (AOAS score 70점이상 ) 를얻을수있었다. 3. 각술식간의비교에서중족골두배굴절골술이가장좋은결과를보였고, 중족골두제거술, 관절재형성술순이었다. 이상의결과에서, 비록증례의수가적어그결과를통계적인처리는할수없었지만 Smillie stage III 이상의진행된진구성 reiberg 병환자에서중족골두절제술, 관절재형성술그리고중족골두배굴절골술을이용하여치료할경우 좋은결과가예상이되고특히, 중족골두배굴절골술은가장좋은결과를보이는술식이라사료된다.
