Pehea e hoʻoponopono ai i nā haʻihaʻi ʻo Distal Humerus me ka hoʻohana ʻana i nā pā?

ʻO nā haʻihaʻi hoʻoneʻe o ka humerus mamao i nā pākeke he pilikia paʻakikī ma muli o ke anatomy paʻakikī o ka hui kuʻekuʻe, nā ʻāpana haʻi liʻiliʻi, a me ka nui o ka iwi subchondral. Hoʻokumu ʻia nā kolamu ʻaoʻao a me waena o ka humerus distal i kahi paʻa triangular paʻa. Hoʻopilikia ʻia kēia ʻano hana triangular paʻa ma hope o nā haʻi ʻana o ka humerus, ʻoi aku ka paʻakikī o nā ʻano ʻano AO C.

Ke kumu

I loko o ka puke AO Internal Fixation Technique i paʻi ʻia i ka makahiki 1979, no ka haʻihaʻi ʻia o ka humerus distal, ua ʻōlelo ka hui AO e kau ʻia nā papa i 90° kekahi i kekahi, hoʻokahi medial a i ʻole ʻaoʻao a hoʻokahi hope (1).

Nā ʻanuʻu ʻenehana (nā loina AO no ka mālama ʻana i ka haki)

a: Ka hana hou ʻana o ka trochlear a me ka capitellum.

bc: Ma hope o ka hōʻemi ʻana i nā ʻāpana iwi articular ʻekolu, e wili i ka uea Kirschner ma ka ʻaoʻao ʻē aʻe. Hiki ke hoʻohana ʻia ka uea Kirschner ma ke ʻano he uea alakaʻi no ka wili cannulated 3.5mm, a i ʻole hiki ke hoʻokomo ʻia kahi wili e like me ka uea Kirschner.

d: E hoʻohana i ka uwea Kirschner no ka hoʻohui ʻana i ka ʻāpana iwi articular i ke kumu humeral

e: No ka hoʻoponopono ʻana i ka ʻāpana articular i ka humerus, pono e kau mua i kahi LCP anatomic ma ka ʻili hope o ka humerus, a hiki ke waiho ʻia kahi pā ma hope o ka capitulum me ka ʻole o ka cartilage. Hiki ke kau ʻia ka LCP anatomical medial ma ka piko waena o ka humerus e hoʻonui i ka paʻa. No ka pohō nui o ka iwi a i ʻole ka hoʻohaʻahaʻa metaphyseal koʻikoʻi, hoʻokomo ʻia nā LCP ʻelua ma 90° i kekahi i kekahi, no ka mea, hāʻawi kēia hoʻonohonoho i ka paʻa biomechanical maikaʻi aʻe. Pono e mālama i ka pale ʻana i ke komo ʻana i ka hui i ka wā e hoʻohana ai i nā wili hoʻopaʻa kihi.

Hoʻohālikelike o nā pā kila like a kū pololei

Ma ka 1995 Mechanics Study Comparing Dual Plates for the Treatment of Distal Humeral Fractures, ua hoʻohālikelike ʻia nā hopena o nā hoʻokomo ʻana o ʻeono mau pā (A, pālua hope ʻelua; B, pā ulnar hope, ʻaoʻao i ka pā radial; C, medial and lateral plate; D, medial to the ulnar plate, posterior to the radial plate; E, fracture-plate; ʻO ke kumu hoʻohālike o nā haʻihaʻi koʻikoʻi me nā wili waena a me ka ʻaoʻao), e kuhikuhi ana he nui nā haʻihaʻi e hiki ke mālama ʻia me nā papa pālua i nā wahi like ʻole e mālama ai, akā no nā haʻihaʻi koʻikoʻi, ua hoʻoholo kēia haʻawina ʻo ka hoʻopili ʻana o ka pā medial-lateral i hui pū ʻia me ka hoʻopaʻa screw e hoʻomaikaʻi nui i ka ʻoʻoleʻa a me ka ikaika loa (3).

Ua hōʻike ʻo Ata C (4) et al he ʻano paʻa ka paʻa ʻana o kahi pā kūpaʻa me ka pā posterolateral a me ʻehā 2.7 mm distal screws me kahi ʻōnaehana pā like i ka mālama ʻana i nā haʻihaʻi intra-articular o ka humerus distal. Hiki ke hoʻopau ʻia ka ʻeha o ka poʻe maʻi ma muli o ka ʻili o ka pā lateral, ʻoi aku ka lahilahi a me ka poʻe kahiko, me ka pā posterolateral.
