Uzilungisa njani iiNdawo ze-Distal Humerus usebenzisa iiPlates?

Ukufuduswa kwe-fractures ye-distal humerus kubantu abadala kuyingxaki enzima ngenxa ye-anatomy eyinkimbinkimbi ye-elbow joint, amaqhekeza amancinci, kunye nenani elincinci le-subchondral bone. Iikholomu ezisecaleni kunye nezangaphakathi ze-distal humerus zenza isakhelo esizinzile se-triangular. Esi sikhokelo esizinzile se-triangular siphazamiseka emva kokuphuka kwe-humerus distal, ngokukodwa i-AO C-type fractures enzima.

Imvelaphi

Kwincwadi ye-AO ye-Internal Fixation Technique epapashwe kwi-1979, ngenxa yeefractures ze-distal humerus, iqela le-AO lincoma ukuba amacwecwe abekwe i-90 ° komnye nomnye, enye i-medial okanye i-lateral kunye neyomva (1).

Amanyathelo obugcisa (imigaqo ye-AO yonyango lokwaphuka)

a: Ukwakhiwa ngokutsha kwetrochlear kunye necapitellum.

bc: Emva kokunciphisa amaqhekeza amathathu amathambo e-articular, yomba ucingo lwaseKirschner kwelinye icala. Ucingo lweKirschner lunokusetyenziswa njengocingo lwesikhokelo kwi-screw ye-cannulated eyi-3.5mm, okanye i-screw ingafakwa ngokuhambelana nocingo lwe-Kirschner.

d: Sebenzisa ucingo lweKirschner lwexeshana ukudibanisa iqhekeza lethambo le-articular kwishaft ye-humeral

e: Ukulungisa i-articular fragment kwi-humerus, i-LCP ye-anatomic kufuneka iqale ibekwe kwi-posterior surface ye-humerus, kwaye iplate ingafakwa emva kwe-capitulum ngaphandle kwe-cartilage. I-LCP ye-anatomical ephakathi inokubekwa kwi-medial crest ye-humerus ukuphucula uzinzo. Ukulahleka kwethambo elibi okanye ukuqhutyelwa kwe-metaphyseal enzima, ukubekwa kwee-LCP ezimbini kwi-90 ° komnye nomnye kucetyiswa, njengoko olu lungelelwaniso lubonelela ngokuzinza okungcono kwe-biomechanical. Kufuneka kuthathwe unonophelo ukuphepha ukungena kwi-joint xa usebenzisa izikrufu ze-angle stabilization.

Ukuthelekiswa kweepleyiti zensimbi ezihambelanayo kunye nezithe nkqo

Kuphononongo lwe-Mechanics ka-1995 Ukuthelekisa iiPlati ezimbini zoNyango lwe-Distal Humeral Fractures, iziphumo zokubeka iipleyiti ezintandathu zafaniswa (A, ipleyiti ephindwe kabini yangasemva; B, ipleyiti yangasemva ye-ulnar, i-lateral ukuya kwi-radial plate; i-C, i-medial kunye ne-lateral plate; D, i-medial kwi-plate ye-ulnar, i-plateerior kwi-plateerior kunye ne-radial mediapart kunye ne-radial mediapart; i-fracture; F, imodeli ye-fractures enzima edibeneyo kunye ne-screws ye-medial kunye ne-lateral), ebonisa ukuba i-fractures eninzi inokunyangwa ngamacwecwe aphindwe kabini kwiindawo ezahlukeneyo zonyango, kodwa ngenxa yokuphazamiseka okukhulu, olu pho nonongo lugqibe kwelokuba ukulungiswa kwepleyiti ephakathi kunye ne-screw fixation kuphucula kakhulu ukuqina kunye namandla okugqibela (3).

I-Ata C (4) et al ibonise ukuba ipleyiti ethe nkqo ene-posterolateral plate kunye ne-screws ezine ze-distal ezine-2.7 mm zazinozinzo olufanayo njengenkqubo yeplate ehambelanayo kunyango lwe-intra-articular fractures ye-distal humerus. Ukukhathazeka kwesigulane ngenxa yokucaphuka kwesikhumba se-lateral plate, ingakumbi izigulane ezincinci kunye nezalupheleyo, zinokupheliswa kunye ne-posterolateral plate.
