Olunaku: October 2025
Omusango: Catastrophic Hardware Migration / Revision Posterior Spinal Instrumentation
Ekikulu Ekivaamu: Okuggya omuggo ogw’omugongo ogusenguddwa mu mutendera gumu okuva ku nsalo y’omugongo mu bujjuvu, nga kugobererwa okunyweza enzimba mu bujjuvu nga tukozesa Enkola ya XC Medico® Premium ey’okukola ebitundu by’omubiri ebiyitibwa Polyaxial System. Obudde bwonna awamu obw’okulongoosebwa: eddakiika 155. Omulwadde yakungaanyizibwa mu ngeri ey’obukuumi ku lunaku olw’okubiri oluvannyuma lw’okulongoosebwa.

Okwanjula Omusango

Ebibalo by’abalwadde n’ebyafaayo by’obujjanjabi

• Omulwadde: Carlos Mendoza (atamanyiddwa mannya ge)
• Emyaka: Emyaka 52
• Ekikula ky’omuntu: Omusajja
• Okusooka okuzuula: Obulwadde bwa thoracolumbar scoliosis obw’amaanyi mu bavubuka
• Ebyafaayo by’okulongoosa: Okutereeza obulema bw’omugongo obw’emabega n’okuyungibwa okubuna T11-L3 kwakolebwa emyaka 15 emabega nga bakozesa enkola ya legacy non-locking pedicle screw system.
• Omusomo ogw’oluvannyuma lw’okulongoosebwa: Tewali bubonero nga gulongooseddwa mu bujjuvu enzimba n’okugatta obulamu mu bujjuvu okumala emyaka egisukka mu kkumi.
• Endwadde endala: Puleesa etali ya maanyi (efugibwa), anywa sigala akola, obungi bw’eby’obuggagga bw’amagumba bulaga nti amagumba gakendedde nga bukyali (T-score -1.8).

Okwanjula Okwemulugunya n’Ebiseera by’Obujjanjabi

Okwemulugunya okukulu: Okutandika mpolampola obulumi bw’ekifuba obutali bwa bulijjo, obusongovu ku ludda olwa kkono nga butangaala okutuuka ku scapula, nga bweyongera okufuuwa ennyo, nga buwerekerwako okusannyalala okutono okw’amaanyi mu bbanga lya wiiki 3. Tewali bulumi bwa mugongo mu kitundu oba obuzibu bw’obusimu mu bitundu ebya wansi bwaloopebwa.

Ebiseera:

• Olunaku 1 (Okuyingizibwa): Omulwadde ayanjuddwa mu kitongole ky’abalwadde ab’amangu ng’atya nti alina obulwadde bw’emisuwa oba amawuggwe. Electrocardiogram ne enzymes z’omutima zaali za bulijjo.
• Okuteebereza: Obuzibu bwa hardware obutandika ekikeerezi oba paravertebral mass.
• Okukulembeza okukuba ebifaananyi: STAT chest radiograph n’oluvannyuma high-resolution thoracic CT scan eragiddwa mu ssaawa 3.

Ebizuuliddwa mu bifaananyi n’okuteekateeka okulongoosa

Ebizuuliddwa mu by’okukuba ebifaananyi (radiography & CT) (Ebifaananyi 1 & 2):

• Embeera y’okuzimba: Okulemererwa kw’ebyuma okujjuvu ku nsengekera ya kkono T11-L3 rod-screw. Sikulufu za kkono eza ‘flat set screws’ zaali zizze emabega ddala, ekyavaamu okusasika kw’okuzimba kwonna.
• Hardware translocation: Omuggo ogw’okutebenkeza ogw’obuwanvu ogwa mm 5.5 ogwa kkono gwali guvudde ddala ku matandiiko ga sikulaapu za pedicle. Nga evugirwa emyaka egy’okufukamira kw’omugongo okutambula obutasalako n’enzirukanya y’okuzimbulukuka, omuggo ogutaziyizibwa gwasenguka waggulu (cephalad) sentimita eziwerako.
• Anatomical compromise: Ensonga ey’okungulu ey’omuggo ogwasenguka yamenya ennyonyi za paravertebral fascial planes, n’esala ensalo za costovertebral, era n’eyingira mu buziba mu kisenge kya kkono eky’ekifuba, n’ewummulako amangu ddala ne pleura n’emitendera emikulu egy’emisuwa egy’omu kifuba.

Okukubaganya ebirowoozo ku kulongoosa: Okusalawo ku bujjanjabi

Obwangu bw’obujjanjabi: Okuleka omuggo gwa titanium ogutali guziyiziddwa munda mu kifo ky’ekifuba ekikyukakyuka kireeta akabi ak’amangu ak’okukutuka kw’omusuwa gw’omusuwa, okukutuka kw’emisuwa egy’omu bitundu by’omubiri, oba okusika omuguwa kw’ekifuba mu kiseera ky’okutambula okw’amangu. Okulongoosa mu bwangu okuggyamu n’okuddamu okuddamu okuzimba byali bya kiragiro.

Eky’okukola 1: Okuggyamu eddagala eriyitibwa Minimalist Video-Assisted Thoracoscopic (VATS) lyokka

Ebizibu: Okuggyawo omuggo ng’oyita mu nkola y’ekifuba kikola ku bulabe obw’amangu obw’omu bitundu by’omubiri naye kireka omulwadde ng’alina ekizimbe ky’ekifuba ekitali kinywevu, ekimenyese. Awatali kuddamu kuddamu kutunula mu maaso, sikulaapu za pedicle ezisigadde zandifunye okunyigirizibwa okw’amaanyi, ekivaako okusumululwa okw’amangu mu aseptic, okulumwa ennyo omugongo, n’okukula kw’obulema obw’okubiri.

Eky’okukola 2: Okuddamu okuddamu okuggule mu kifuba n’olubuto n’emabega nga bigattiddwa

Ebizibu: Okusala ebitundu bibiri eby’enjawulo (anterior thoracotomy for rod retrieval and posterior open approach for spine stabilization) okuyita mu nnaku eziwera kyongera ku budde bwonna obw’okulongoosa okutuuka ku ddakiika 320+. Enzimba eno ey’enkola bbiri esitula nnyo okufiirwa omusaayi, ebizibu by’amawuggwe, n’obudde bw’ekitanda mu ddwaaliro okutuuka ku nnaku 6-8 ezitakka wansi.

Ekyokulonda 3: Okuggya emabega mu mutendera gumu + Okunyweza Cross-Link Fixation (Erondeddwa)

Enkola ey’ekikugu: Okuddamu okuggulawo ekifo ekyali kisaliddwa mu layini y’omu makkati ey’emabega kyasobozesa okutuuka butereevu ku kitanda kya Hardware ekyasigalawo. Ng’akozesa ebyuma eby’enjawulo eby’okuggyamu, omusawo eyalongoosa yagoberera ekitundu ky’omuggo okudda emabega okuva ku ludda olw’emabega, n’aguserengesa n’obwegendereza okuva mu kisenge ky’ekifuba ng’alagirwa ennyo mu ngeri ya fluoroscopic. Kino kyewala okusala ekifuba mu maaso (independent anterior thoracotomy).

Oluvannyuma lw’okuggyibwamu, enkola ya legacy etali nnywevu yakyusibwa n’efuulibwa XC Medico® Premium Polyaxial Pedicle Screw System . Okumalawo ekikolo ekivaako okulemererwa okwasooka, ekizimbe ekipya kyagatta sikulaapu eziteekawo ‘negative-angle buttress set screws’ okuziyiza okusaasaana kw’obuwuzi, nga zigatta wamu n’ebiyungo ebisalasala ebikaluba ebitereezebwa okukola fuleemu ey’enjuyi ennya ezitatambula.

Okulonda ebintu: XC Medico’s Premium Spinal Fixation System — ng’egatta sikulaapu za ‘polyaxial pedicle’ ezirina torque enkulu ne sikulaapu eziteekeddwa mu nkoona etali nnungi (negative-angle set screws) n’ebiyungo ebikalu ebitereezebwa.

Okulongoosa Okukola: Ebikwata ku kulongoosa

Okuteeka mu kifo n’Okubikkula

• Okuteeka omulwadde mu kifo: Okuyimirira ku fuleemu ya Relton-Hall eya bulijjo, okulongoosa okukendeeza ku puleesa y’olubuto okukendeeza ku puleesa y’emisuwa.
• Okubikkulwa: Enkovu eyasooka ey’omu layini wakati ey’emabega yasalibwako. Subperiosteal dissection yakolebwa n’obwegendereza okulaga legacy pedicle screws okuva ku T11 okutuuka ku L3. Operative field exposure etuukiddwaako mu ddakiika 25.

Omutendera gw’okuggya ebikozesebwa n’okugogola ekifuba

• Okunoonyereza: Tulips za left pedicle screw tulips zasangibwa nga nzigule nga set screws teziriiwo ddala. Enkomerero y’omugongo ey’omuggo ogwasenguka yazuulibwa ng’efulumye katono okuva ku kitanda ky’ebinywa by’omugongo (paravertebral muscle bed) okumpi ne T11.
• Okuggyamu: Wansi w’okulondoola okutambula obutasalako mu ngeri ya fluoroscopic ey’ebbali, ebyuma eby’enjawulo ebikwata emirimu egy’amaanyi byassibwa ku mukira ogulabika ogw’omuggo. Nga bakozesa enkola ya controlled, steady axial traction technique, omuggo gwasendebwa okudda emabega okuyita mu nkola yaago ey’okusenguka.
• Clearance check: Omuggo gwaggyibwa bulungi nga tegufunye kuziyiza. Okukebera amangu fluoroscopy n’okugaziwa kw’amawuggwe kwakakasa nti ensalosalo y’amawuggwe yasigala nga bweri nga tewali acute pneumothorax. Obudde bw’omutendera: eddakiika 40.

Revision Fixation & Omutendera gw'okukuŋŋaanya fuleemu enkalu

• Okuwanyisiganya sikulaapu: Sikuluku za legacy ezasumululwa zaggyibwamu. Ebitundu by’amagumba byasalibwako ne bikuzibwa obunene okusobola okuyingizaamu XC Medico® 6.0mm Premium Polyaxial Pedicle Screws, okukakasa nti amagumba gagula mu ngeri ey’oku ntikko mu bitanda by’amagumba ebikendedde.
• Okusiba emiggo: Emiggo emipya egya mm 5.5 egya titanium alloy egyali gikoleddwa nga teginnabaawo gyatuula. Ekikulu, sikulaapu za XC Medico eza reverse negative-angle set screws za torqued okutuuka ku 8 Nm nga bakozesa calibrated drivers. Ekifaananyi ky’obuwuzi kyasika nnyo ebisenge bya tulip munda, ne kimalawo akabi k’okusaasaana.
• Okugatta cross-link: Cross-connectors bbiri ezikaluba ezitereezebwa zassibwa okubuna emiggo gya kkono ne ddyo ku mutendera gwa T12 ne L2. Kino kyakyusa emiggo ebiri egy’enjawulo ne gifuuka fuleemu emu ey’enzimba enkaluba ennyo, ne kifuula okusereba kw’emiggo egy’obuwanvu obutasoboka mu mubiri. Obudde bw’omutendera: eddakiika 70.

Okukendeeza n’okuggalawo okusembayo

Final biplanar fluoroscopy yakakasa obuziba bwa sikulaapu obutuufu, okuteekebwa kw’omuggo mu ngeri entuufu, n’okuddamu okusengeka ensengekera y’omubiri. Ekifo kino kyafukirira bulungi, ne kiteekebwawo ekyuma ekifulumya amazzi wansi w’ebinywa, era ne kiggwa okuggalawo fascial mu layeri eziwera. Obudde bwonna awamu obw’okulongoosebwa: eddakiika 155. Omusaayi ogubalirirwamu okufiirwa: 210 mL. Okuteekebwamu omusaayi: Zero.

Omusomo gw’oluvannyuma lw’okulongoosebwa n’ebivaamu

Okulongoosebwa amangu ddala (POD 0-1) .

Omulwadde yazuukuka ng’obulumi obw’amaanyi mu kifuba bugonjoddwa mangu (VAS yakendeera okuva ku 8/10 nga tannalongoosebwa okutuuka ku 2/10 oluvannyuma lw’okulongoosebwa). Amaloboozi g’omukka aga bulijjo gakakasibwa ku njuyi zombi, ne gagaana nti obulwadde bwa pneumothorax obulwawo. Radiographs oluvannyuma lw’okulongoosebwa zalaga pristine hardware alignment. Akawungeezi ka POD 1, omulwadde yali atudde bulungi ku mabbali g’ekitanda ng’alina obusimu obujjuvu obw’ekitundu kya wansi.

Enteekateeka y’okusiibulwa (POD 2 — Ssaawa 48) .

Ku ssaawa 48 post-op, submuscular drain yaggyibwawo (minimal output). Omulwadde yatuukiriza ebisaanyizo byonna eby’okusiibulwa mu kitongole: okutambula nga yeetongodde ng’atambula bulungi, okumira obulungi mu kamwa, n’okufuga obulumi ng’ayita mu ddagala eriweweeza ku bulumi mu kamwa. Okusiibulwa amangu ku ssaawa 48 kyakendeeza ku bulabe bw’obulwadde obufunibwa mu ddwaaliro n’okukendeeza ku buzito bw’ebitanda mu bitongole.

Okugoberera (Wiiki 6 & Emyezi 3)

Ku myezi 3, Carlos yali talina bulumi bwonna (VAS 0/10) era yali akomyewo ku mirimu gya kikugu emitono. Ebifaananyi eby’omu kifuba n’omugongo ebiddiriŋŋana byakakasa nti zero micro-motion ku nkulungo za screw-rod. Fuleemu ya XC Medico® eya cross-linked yakuuma okukwata enzimba okutuukiridde, nga waliwo obubonero obusooka obw’okuyungibwa kw’amagumba okunywevu nga bunywevu okubuna ebitundu by’omu kifuba.

Ebibuuzo n'okuddamu eby'ekikugu eri Ttiimu z'okuzimba ebizibu ebizibu

Q: Obuwuzi bwa ‘negative-angle buttress’ buziyiza butya set screw back-out bw’ogeraageranya ne standard flat threads?

A: Standard flat oba V-threads zikola empalirizo ya radial ey’ebweru ku bisenge eby’omunda eby’omutwe gwa sikulaapu (tulip) nga binywezeddwa okutuuka ku torque esembayo. Wansi w'okunyigirizibwa kw'ebyuma okw'enzirukanya okw'amaanyi, empalirizo eno eya radial ereetera ebisenge bya tulip okugaziwa katono oba 'splay.' Oluvannyuma lw'okusaasaana okubaawo, okukwatagana kw'obuwuzi kugwa, ne kisobozesa sikulaapu eyateekebwawo okudda emabega. XC Medico’s negative-angle buttress thread erimu geometry y’okusereba wansi n’okudda munda. Torque bw’eteekebwako, amaanyi g’obuwuzi mu butuufu gasika ebisenge bya tulip munda, ne bisiba screw set bulungi ku muggo era ne gamalawo ddala okulemererwa kw’okuzimba okuvugibwa splay.

Q: Lwaki enkola ya cross-link ekakatako mu kulongoosa okw’emabega okw’ekitundu ekiwanvu okuziyiza omuggo okusereba?

A: Emiggo egy’enjawulo egy’enjawulo gyesigamye ku nkwata y’okusikagana ey’ekitundu yokka eya sikulaapu za pedicle ssekinnoomu. Singa omulwadde aba n’omutindo gw’amagumba ogukendeera, okukyusakyusa omugongo okuddiŋŋana kuyinza okuleetera okukyusakyusa mu ngeri entonotono ey’emitwe gya sikulaapu, ne kikendeeza ku kukwata okwo okw’okusikagana okw’ekitundu okumala ekiseera. Okugatta ebiyungo ebisalasala ebitereezebwa kiziba emiggo gya kkono ne ddyo mu fuleemu ya bbokisi enkalu ey’enjuyi ennya. Okuyungibwa kuno okwa multi-planar kukyusa okunyigirizibwa kw’okusala mu kizimbe kyonna, ekifuula okwetongodde okusereba kw’omuggo ogw’obuwanvu mu ngeri ey’ebyuma obutasoboka ne bwe kiba nti ekiyungo kya sikulaapu kimu kifuna okwambala kwa micro-fretting.

Ekiteeso ky’omuwendo gw’abasaasaanya: Okufuga ebifo bya ttenda mu bitundu

• The Commercial Edge: Okwanjula ttiimu z’okugula amalwaliro eky’okugonjoola ekizibu kya yinginiya ekikendeeza ku bulabe bw’okuddamu okusoma n’okukendeeza ku nsaasaanya yonna ey’emisango egy’enjawulo ebitundu 55% kiteekawo omuwendo gw’ebyobusuubuzi ogutaliiko kye gufaanana mu kiseera ky’okwekenneenya ttenda.
• Obwesige mu bujjanjabi: Okuwa abasawo abalongoosa omugongo ebikozesebwa ebikakasibwa (ISO 13485) ebya TC4 Titanium ebirina okugumiikiriza kw’ebyuma ebitono (sub-micron machining tolerances) kikakasa okwesigamizibwa kw’okusiba kwa torque enkulu, okukuuma erinnya lyabwe mu bitongole okuva ku kulemererwa kw’okuzimba okw’omutendera ogusembayo.
