Qhia peb lub tshuab kho qhov txhab intramedullary rau kev tawg pob txha calcaneal.

Tam sim no, txoj kev phais mob uas siv ntau tshaj plaws rau kev tawg pob txha calcaneal yog kev kho sab hauv nrog lub phaj thiab ntsia hlau los ntawm txoj kev nkag mus rau hauv lub sinus tarsi. Txoj kev nthuav dav uas zoo li tus "L" sab nraud tsis raug nyiam siv hauv kev kho mob vim muaj teeb meem ntau dua ntawm qhov txhab. Kev kho lub phaj thiab ntsia hlau, vim nws cov yam ntxwv biomechanical ntawm kev kho eccentric, muaj kev pheej hmoo ntau dua ntawm varus malalignment, nrog rau qee qhov kev tshawb fawb qhia txog qhov tshwm sim tom qab phais mob ntawm kwv yees li 34%.

Yog li ntawd, cov kws tshawb fawb tau pib kawm txog cov txheej txheem kho intramedullary rau cov pob txha tawg calcaneal los daws ob qho teeb meem ntsig txog qhov txhab thiab qhov teeb meem ntawm kev tsis sib haum xeeb ntawm cov pob txha varus thib ob.

01 Nkev siv tes ntsia hlau hauv nruab nrab

Cov txheej txheem no tuaj yeem pab txo qis los ntawm txoj kev nkag mus rau hauv sinus tarsi lossis nyob rau hauv kev taw qhia arthroscopic, xav tau cov nqaij mos mos tsawg dua thiab tej zaum yuav txo lub sijhawm pw hauv tsev kho mob. Txoj hauv kev no yog siv rau hom II-III pob txha tawg, thiab rau cov pob txha calcaneal uas tau sib xyaw ua ke, nws yuav tsis muab kev saib xyuas zoo ntawm kev txo qis thiab tej zaum yuav xav tau kev kho ntxiv.

02 Stus ntsia hlau intramedullary dav hlau

Tus ntsia hlau intramedullary ib daim dav hlau muaj ob lub ntsia hlau ntawm qhov kawg proximal thiab distal, nrog rau tus ntsia hlau tseem ceeb hollow uas tso cai rau kev txuas pob txha los ntawm tus ntsia hlau tseem ceeb.

03 Mtus ntsia hlau intramedullary ulti-plane

Tsim los ntawm cov qauv peb-seem ntawm cov pob txha calcaneus, lub kaw lus kho sab hauv no suav nrog cov ntsia hlau tseem ceeb xws li cov ntsia hlau protrusion uas muaj peev xwm nqa tau thiab cov ntsia hlau txheej txheem tom qab. Tom qab txo qis los ntawm txoj kev nkag mus rau hauv sinus tarsi, cov ntsia hlau no tuaj yeem muab tso rau hauv qab pob txha mos rau kev txhawb nqa.

Muaj ntau qhov kev tsis sib haum xeeb txog kev siv cov ntsia hlau intramedullary rau cov pob txha tawg calcaneal:

1. Kev haum raws li qhov nyuaj ntawm qhov tawg: Nws tau sib cav seb qhov tawg yooj yim tsis xav tau cov ntsia hlau intramedullary thiab qhov tawg nyuaj tsis haum rau lawv. Rau Sanders hom II / III qhov tawg, cov txheej txheem ntawm kev txo qis thiab ntsia hlau kho los ntawm txoj kev nkag mus rau sinus tarsi yog qhov paub tab, thiab qhov tseem ceeb ntawm cov ntsia hlau intramedullary tseem ceeb yuav raug nug. Rau cov pob txha tawg nyuaj, qhov zoo ntawm txoj hauv kev nthuav dav "L" tseem tsis tau hloov pauv, vim nws muab kev cuam tshuam txaus.

2. Yuav tsum muaj ib txoj hlab ntsha medullary cuav: Lub calcaneus yeej tsis muaj txoj hlab ntsha medullary. Kev siv ib tug ntsia hlau loj hauv medullary yuav ua rau raug mob hnyav lossis poob pob txha.

3. Nyuaj rau kev tshem tawm: Feem ntau hauv Suav teb, cov neeg mob tseem raug tshem tawm cov khoom siv tom qab kho pob txha tawg. Cov ntsia hlau sib xyaw nrog kev loj hlob ntawm pob txha thiab kev ntxig cov ntsia hlau sab hauv qab pob txha cortical tuaj yeem ua rau nyuaj rau kev tshem tawm, uas yog qhov kev txiav txim siab hauv kev siv kho mob.
