Mid Humeral Fracture
The upper arm is made up of a bone called the humerus. The head of the humerus fits into a shallow socket in your scapula (shoulder blade) to form the shoulder joint. The humerus narrows down into a cylindrical shaft and joins at its base with the bones of the lower arm to form the elbow joint.
Mid humeral fractures are fractures that occur in between the shoulder joint and elbow. They may occur as a simple fracture where the bone is not shattered, wedge fracture where the bone breaks to form a wedge, or complex fracture where the bone is shattered into many pieces.
Mid humeral fractures are often caused by:
- Direct blow or a bending force on the mid humerus
- Falling onto an outstretched arm
- Violent muscle contraction in sports such as weight lifting
Patients usually present with considerable pain, and swelling. Shortening of the arm is apparent when significant displacement of the bones occurs.
Mid humeral fractures can be diagnosed through X-ray imaging and ultrasound.
Most fractures can be successfully treated with conservative treatment. Your doctor may allow the arm to hang next to your side so that the bones align and will place it in a hanging arm cast or a splint for 1-3 weeks, and then in a functional brace.
Surgical treatment is recommended for the following conditions:
- Fractures that cannot be managed conservatively
- Segmental fractures
- Pathologic fractures (bone tumor)
- When blood vessels are injured
- Patients who need to have upper extremity weight-bearing capability
- Open fractures where the skin is broken by the fractured bone
- Obese patients in whom alignment is difficult
Surgery involves open reduction and internal fixation (ORIF). This procedure is usually performed under general anesthesia. First your broken bones are put back into their normal anatomic position. Internal fixation devices such as plates, screws, or intramedullary implants are then used to hold your broken bones together. You will be placed in a dressing and/or cast following your procedure.
Mvunjiko wa katikati wa mkono Mkono wa juu umefanyizwa na mfupa unaoitwa humerus. Kichwa cha humerus huingia katika sehemu ya chini ya kiwiko (sculpule) ili kufanyiza kiungo cha bega. Mfupa wa mkono hupungua na kuwa umbo la silinda na kuungana na mifupa ya mkono wa chini ili kufanyiza kiungo cha kiwiko. Mvunjiko wa katikati wa humeral ni mivunjiko inayotokea kati ya kiungo cha bega na kiwiko. Mshtuko wa mgongo unaweza kutokea kama mfupa rahisi ambapo mfupa haujapondwa, mfupa wa mviringo ambapo mfupa huvunjika na kuunda mviringo, au mfupa tata ambapo mfupa umevunjika vipande vipande. Mvunjiko wa humeral wa kati mara nyingi husababishwa na: - Pigo la moja kwa moja au nguvu ya kugeuka kwenye humerus ya kati - Kuanguka kwenye mkono ulioinuliwa - Mshuko mkali wa misuli katika michezo kama vile kuinua uzito Wagonjwa kwa kawaida wanapatikana na maumivu makubwa, na uvimbe. Kupunguzwa kwa urefu wa mkono huonekana wakati mifupa inapohamishwa sana. Mvunjiko wa sehemu ya kati ya kiwiko cha mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono wa mkono. Mvunjiko mwingi wa miguu waweza kutibiwa kwa mafanikio kwa matibabu ya kihafidhina. Daktari wako anaweza kuruhusu mkono wako kuegeshwa kando yako ili mifupa iwe sawa na kuuweka katika gips ya mkono wa kunyongwa au splint kwa wiki 1-3 na kisha katika brace ya kazi. Upasuaji hupendekezwa kwa hali zifuatazo: - fractures ambazo haziwezi kusimamiwa kwa njia ya kihafidhina - fractures ya sehemu - fractures ya pathological (tumor ya mfupa) - Wakati mishipa ya damu imeharibiwa - Wagonjwa ambao wanahitaji kuwa na uwezo wa kubeba uzito wa mguu wa juu - fractures wazi ambapo ngozi imevunjwa na mfupa uliovunjika - Wagonjwa wenye uzito mzito ambao usawa ni ngumu. Kwa kawaida utaratibu huo hufanywa chini ya anesthesia ya jumla. Kwanza mifupa yako iliyovunjika huwekwa tena katika hali yake ya kawaida ya kianatomia. Vifaa vya ndani kama vile sahani, vijiti, au viungo vya ndani vya utumbo hutumiwa kushikilia mifupa yako iliyovunjika pamoja. Utawaweka katika dressing na au gips kufuatia utaratibu wako.
