Ihlombe liyilunga elinobubanzi obukhulu bokunyakaza emzimbeni, futhi ukuthunjwa kwehlombe kuyisici esibalulekile semisebenzi eminingi esiyenzayo ngamaphethelo angaphezulu. Ngokukhethekile, ukuthunjwa kwehlombe kungenye yezinyathelo ezimbalwa ezihlangene ezinobubanzi obujwayelekile okungenani obungama-degree angu-180.
Isebenza kanjani inhlangano yokuthunjwa kwamahlombe?
Esinye isizathu salolu hlu olubanzi ukuthi luyinkimbinkimbi kakhulu kunokunyakaza endaweni ehlangene yehlombe kuphela: ukuthunjwa kudinga ukunyakaza okuhlelekile kwehlombe kanye nejoyinti ye-scapulothoracic. Lokhu kuhlanganisa kuthatha igama lika isigqi se-scapulohumeral (noma i-scapulo-thoracic). Inhloso eyinhloko yalesi "sigqi se-scapulo-humeral" ukugcina isikhundla esihle sokunyakaza okuhlukahlukene kwekhanda le-humeral.
I-humerus ibanjwe endaweni (ku-fossa ehlangene yehlombe) yimisipha ye-rotator cuff kanye neminye imisipha eqinisa i-scapulae: i-trapezius (ephakeme / ephakathi / ephansi), i-levator scapulae, i-rhomboids, ne-serratus yangaphambili.
Uma sihambisa ingalo yethu ngokuthunjwa, i-humerus ihlala ngaphakathi kwesokhethi ye-scapular, njengoba i-scapula inyakaza ngesikhathi esifanayo (ngokujikeleza phezulu) ivumela i-humerus futhi ivumele indawo ukuba ihambe ngokukhululekile. .
Ngenxa yemikhuba engemihle ye-postural, ukulimala, kanye nesikhathi esiningi esichithwa namahlombe ethu egobile futhi ezungeza ngaphakathi, abaningi bethu bavame ukuthuthukisa ukungalingani kwemisipha (ikakhulukazi ku-serratus anterior kanye ne-tapezie) ephazamisa ukujikeleza okuphezulu kwe-scapula. .
Ngenxa yalokhu buthakathaka kwemisipha, i-humerus ingakwazi ukucindezela kalula ingxenye engezansi yenqubo ye-acromion (ingxenye ye-scapulae) ngesikhathi somzamo wokuthumba futhi, ngenxa yalokho, ingabangela ukuphazamiseka kwehlombe noma i-rotator cuff disorders. Yingakho kubalulekile ukusebenza ekuhambeni kwehlombe futhi uqinise imisipha esekela yonke "uhlelo."
