Ukuphuka kwekhanda le-radial kanye nentamo ye-radial kuyizinto ezivamile zokuphuka kwelunga le-elbow, okuvame ukubangelwa amandla e-axial noma ukucindezeleka kwe-valgus. Uma ilunga le-elbow lisesimweni esandisiwe, ama-60% amandla e-axial engalweni adluliselwa eduze kwekhanda le-radial. Ngemva kokulimala kwekhanda le-radial noma intamo ye-radial ngenxa yamandla, amandla okugunda angathinta i-capitulum ye-humerus, okungenzeka kuholele ekulimaleni kwamathambo kanye ne-cartilage.
Ngo-2016, uClaessen wathola uhlobo oluthile lokulimala lapho ukwaphuka kwekhanda/intamo ye-radial kwakuhambisana nomonakalo wethambo/uqwanga ku-capitulum ye-humerus. Lesi simo sabizwa ngokuthi “isilonda sokuqabulana,” kanye nokuqhekeka okwakuhlanganisa le nhlanganisela okubizwa ngokuthi “ukuqhekeka kokuqabulana.” Embikweni wabo, bafaka amacala ayi-10 okuqhekeka kokuqabulana futhi bathola ukuthi amacala ayi-9 ayenokuqhekeka kwekhanda kwe-radial okuhlukaniswe njengohlobo lwe-Mason II. Lokhu kusikisela ukuthi ngokuqhekeka kwekhanda kwe-radial yohlobo lwe-Mason II, kufanele kube nokuqwashisa okukhulu ngokuqhekeka okungenzeka okuhambisana ne-capitulum ye-humerus.
Emtholampilo, ukwaphuka kokuqabulana kuthambekele kakhulu ekuxilongweni okungalungile, ikakhulukazi ezimweni lapho kunokushintshwa okukhulu kokuphuka kwekhanda/intamo okuqondile. Lokhu kungaholela ekungabheki ukulimala okuhlobene ne-capitulum ye-humerus. Ukuze bahlole izici zomtholampilo kanye nokwanda kokuqhekeka kokuqabulana, abacwaningi bakwamanye amazwe benze ukuhlaziywa kwezibalo ngobukhulu besampula obukhulu ngo-2022. Imiphumela imi kanje:
Ucwaningo luhlanganise iziguli eziyi-101 ezazinezinhlungu zekhanda/intamo eziqhekekile ezelashwa phakathi kuka-2017 no-2020. Ngokusekelwe ekutheni zazinokuqhekeka okuhlobene yini kwe-capitulum ye-humerus ohlangothini olufanayo, iziguli zahlukaniswa ngamaqembu amabili: iqembu le-capitulum (Iqembu I) kanye neqembu elingelona i-capitulum (Iqembu II).
Ngaphezu kwalokho, ukuqhekeka kwekhanda le-radial kwahlaziywa ngokusekelwe endaweni yazo yomzimba, eyahlukaniswa yaba yizifunda ezintathu. Eyokuqala yindawo ephephile, eyesibili indawo yangaphambili ye-medial, kanti eyesithathu indawo yangemuva ye-medial.
Imiphumela yocwaningo iveze okutholakele okulandelayo:
- Uma ukuhlukaniswa kwekhanda le-radial kuphakeme nge-Mason, kulapho ingozi yokuqhekeka kwekhanda le-capitulum ehambisana nayo inkulu khona. Amathuba okuqhekeka kwekhanda le-radial lohlobo lwe-Mason I ahlotshaniswa nokuqhekeka kwe-capitulum ayengu-9.5% (6/63); ngohlobo lwe-Mason II, kwakungu-25% (6/24); kanti ngohlobo lwe-Mason III, kwakungu-41.7% (5/12).
- Lapho ukuphuka kwekhanda le-radial kwanda ukuze kuhilele intamo ye-radial, ingozi yokuphuka kwe-capitulum yehla. Izincwadi azizange ziveze noma yiziphi izimo zokuphuka kwentamo ye-radial okuhambisana nokuphuka kwe-capitulum.
- Ngokusekelwe ezifundeni zomzimba zokuqhekeka kwekhanda eliyi-radial, ukuqhekeka okutholakala ngaphakathi "kwendawo ephephile" yekhanda eliyi-radial kwakunengozi enkulu yokuhlotshaniswa nokuqhekeka kwe-capitulum.
▲ Ukuhlukaniswa kwe-Mason kokuqhekeka kwekhanda eliyi-radial.
▲ Icala lesiguli esiphuke ngokuqabulana, lapho ikhanda eliyi-radial laliboshwe ngepuleti lensimbi nezikulufo, kanti i-capitulum ye-humerus yalungiswa kusetshenziswa izikulufo ze-Bold.
