Ukunqunyulwa kwelungu elisezantsi kunempembelelo ebalulekileyo ekuhambeni kwamalungu kunye nezihlunu zomlenze ongezantsi.Emva kokunqunyulwa, indawo yokunyakaza okuhlangeneyo idla ngokuncitshiswa, okukhokelela kwiikontrakthi ezingafunekiyo zamalungu ngoko ke kunzima ukuhlawulela nge-prostheses.Ekubeni ama-prostheses asezantsi aqhutywa lilungu elishiyekileyo, kubalulekile ukuqonda imiphumo yokunqunyulwa kumalungu amakhulu kwaye kutheni utshintsho olunjalo lwenzeka.
(I) Iziphumo zokunqunyulwa kwethanga
Ubude be-stump bunempembelelo ebalulekileyo kumsebenzi we-hip joint.Okukhona sisifutshane isiphunzi, kokukhona kuba lula ukuba isinqe sixhwilwe, sijikelezise ngaphandle kwaye sibhetyebhetye.Ngamanye amazwi, ngakolunye uhlangothi, i-gluteus medius kunye ne-gluteus minimus, edlala indima enkulu ekubanjweni kwe-hip, igcinwe ngokupheleleyo;ngakolunye uhlangothi, iqela le-adductor muscle linqunyulwa kwindawo ephakathi, okubangela ukuhla kwamandla emisipha.
(II) Iziphumo zokunqunyulwa komlenze ongezantsi
Ukunqunyulwa kwaba nefuthe elincinci kuluhlu lokuguqa kwamadolo kunye nokwandiswa kunye namandla omzimba.I-quadriceps yiqela eliphambili le-muscle yokwandiswa kunye nokuyeka kwi-tuberosity ye-tibial;iqela eliphambili le-muscle elidlala indima kwi-flexion yi-posterior thigh muscle group, eyeka malunga nokuphakama okufanayo kunye ne-condyle ye-tibial medial kunye ne-fibular tuberosity.Ngoko ke, izihlunu ezingasentla azonakaliswa phakathi kobude obuqhelekileyo bokunqunyulwa komlenze ongezantsi.
(III) Iziphumo ezivela ngenxa yokunqunyulwa kwenyawo
Ukunqunyulwa kwe-metatarsal ukuya enzwaneni kwakunempembelelo encinci okanye akukho nto ekusebenzeni kwemoto.Ukunqunyulwa kwi-joint tarsometatarsal (i-Lisfranc joint) ukuya kwiziko.Ibangela ukungalingani okugqithisileyo phakathi kwe-dorsiflexors kunye ne-plantar flexors, ebeka phambili kwi-plantar flexion contracture kunye ne-ankle inversion position.Oku kungenxa yokuba emva kokunqunyulwa, umsebenzi wethole le-triceps njenge-plantar flexor prime mover igcinwe ngokupheleleyo, ngelixa ii-tendon zeqela le-dorsiflexor zinqunywe ngokupheleleyo, ngaloo ndlela zilahlekelwa ngumsebenzi wazo ofanelekileyo.
