Fraktura ng Ulo ng Radius Impormasyon

Ano ang nararamdaman mo

Maaaring mararamdaman mo ang matulis na sakit sa labas na bahagi ng iyong siko. Dito matatagpuan ang radial head. Karaniwang kumakalat ang sakit pababa sa iyong forearm o pataas patungo sa iyong balikat. Maaari mo ring mapansin ang pamamaga at pamumula sa paligid ng kasukasuan. Karaniwang mga senyales ito pagkatapos ng pagkabagsak o direktang pagtama.

Bawat beses na yumuyuko o nagwawasto ka ng iyong braso, maaaring lumakas ang sakit. Karaniwang pinakamahirap ang mga galaw na pag-ikot. Ang pag-ikot ng hawakan ng pinto, paggamit ng screwdriver, o pag-angat ng bag ng mga bilihin ay maaaring magdulot ng biglaang pagtaas ng hindi komportableng pakiramdam. Maaaring mahirapan kang i-rotate ang palad pataas o pababa. Ang mga simpleng gawain tulad ng pagtatakip ng damit sa loob ng pantalon o pag-abot sa likod ng likod para i-fasten ang bra ay maaaring maging hamon. Maaaring instintibong hawakan mo ang iyong braso malapit sa iyong katawan upang protektahan ito.

Ang pagpahinga ng braso sa isang unan ay madalas tumutulong upang bawasan ang presyon sa kasukasuan. Gayunpaman, ang pagpapanatili ng siko na ganap na tahimik sa loob ng masyadong matagal ay maaaring magdulot ng pagiging matigas at masikip. Maaaring gumising ka sa gabi dahil sa pulso ng sakit o dahil hindi mo mahanap ang komportableng posisyon. Karaniwang hindi posible ang pagtulog sa nasugatang gilid. Kahit ang pagpahinga sa iyong likod ay maaaring masaktan kung ang iyong braso ay mahuhulog sa gilid.

Ang kabiguan ng iyong mga sintomas ay nakadepende sa kung gaano karami ang paggalaw ng buto. Kung matatag ang fracture, maaari mong pamahalaan ito gamit ang pagpapagaan ng sakit at banayad na paggalaw. Kung ang mga piraso ng buto ay nasa maling posisyon, ang sakit ay maging mas matindi at patuloy. Maaaring mararamdaman mo ang pakiramdam ng pag-click o pag-giling kapag gumagalaw ang iyong siko. Nangyayari ito dahil ang mga basag na piraso ay nagkikiskisan sa isa't isa.

Mahalagang hayaang suriin ng iyong surgeon ang saklaw ng sugat. Itataya nila kung ang fracture ay simpleng kumplikado lamang. Tinitiyak nito kung kailangan mo ng operasyon o kung sapat na ang konsersibong paggamot. Huwag subukang pumasa sa sakit. Pakikinig sa iyong katawan at iwasan ang mga gawain na nagdudulot ng matulis na hindi komportableng pakiramdam. Ang maagang pag-aalaga ay tumutulong upang maiwasan ang pangmatagalang pagiging matigas at tinitiyak na ang iyong siko ay gumaling sa pinakamainam na posisyon na posible.

Ano ang nangyayari talaga

Ang iyong siko ay isang kumplikadong bisagra na binubuo ng tatlong buto na nagtatagpo sa iisang kasukasuan. Ang radial head ay ang bilugang tuktok ng iyong buto sa forearms, na gumaganap bilang shock absorber at stabilizer para sa gilid ng iyong siko. Kapag nahulog ka sa isang nakalatag na kamay, madalas na kinukuha ng maliit na butong ito ang pinakamalaking epekto ng impact.

Sa isang displaced fracture, ang buto ay sumisira at lumilipat sa labas ng tamang posisyon. Ito ay nagdudulot ng pagkagambala sa makinis na ibabaw na nagpapahintulot sa iyong braso na umikot. Maaaring maranasan mo ang sakit sa panlabas na bahagi ng iyong siko dahil ang natural na pagkakahanay ng kasukasuan ay nasira. Ang mga nakapaligid na tisyu, kabilang ang mga ligament na gumaganap tulad ng mga lubid upang panatilihin ang kasukasuan, ay maaari ring masira. Ang kombinasyong ito ng basag na buto at maluwag na ligament ay nagdudulot ng instability, na nagpaparamdam sa iyong siko na mahina o parang magbibigay.

Kung ang buto ay magulo sa maraming piraso, kailangang desisyonin ng iyong surgeon kung ito ay aayusin o palitan. Ang isang metal na radial head implant ay maaaring ibalik ang shock-absorbing na function kapag ang buto ay masyadong sira upang ayusin. Ang palitan na ito ay nag-aalok ng maaasahang resulta para sa mga kumplikadong pagbasag. Sa ilang kaso, ang maagang pag-alis ng basag na piraso ay nagpapahintulot sa 96% ng mga pasyente na makamit ang sapat na function sa mahabang panahon, bagama't ang mga pagbabago sa pagkasira ay maaaring lumitaw sa X-ray sa huli.

Ang kabiguan ng iyong sugat ay nakadepende sa kung ilang istruktura ang kasangkot. Ang mga simpleng fracture ay madalas na gumagaling nang maayos sa pamamagitan ng pahinga. Ang mas kumplikadong mga sugat, kung saan maraming buto at ligament ang nasira, ay nangangailangan ng maingat na pagpaplano upang ibalik ang stability. Ang pag-unawa sa mga pattern na ito ay tumutulong sa iyong surgeon na pumili ng tamang paraan upang muling gawin ang iyong siko na gumagalaw nang ligtas.

Mga maitutulong namin dito

Ang iyong pinagdaanan ay nakadepende sa kung gaano kalala ang iyong sugat. Si Dr. Kieran Hirpara, isang surgeon sa itaas na bahagi ng katawan sa Mater Private Hospital Rockhampton, gabayan ang aming mga pasyente sa paggawa ng desisyong ito batay sa iyong partikular na pattern ng fracture. Karamihan sa mga sugat ay nagsisimula sa isang panahon ng pahinga at banayad na paggalaw. Layunin naming bawasan ang pamamaga at panatilihin ang paggalaw ng iyong siko nang hindi ito pinipilit. Karaniwang tumatagal ang yugto ng self-management na ito ng ilang linggo. Tumutulong ang physiotherapy upang mabawi ang lakas at koordinasyon habang nagsisimula nang gumaling ang buto. Para sa maraming pasyente na may stable, minimally displaced fractures, sapat na ang non-surgical na landas na ito.

Kung mananatili ang sakit, maaari naming pag-usapan ang medical management upang matulungan kang makayanan ang sitwasyon habang nagse-settle ang sugat. Ang mga over-the-counter na pain relievers o anti-inflammatories ay maaaring gamitin upang pamahalaan ang hindi komportableng pakiramdam sa maikling panahon. Sa ilang kaso, maaari naming imungkahi ang isang injection. Ang mga cortisone injections ay nagbabawas ng pamamaga at maaaring magbigay ng ginhawa sa loob ng ilang linggo. Ang mga hyaluronic acid injections ay naglalayong maglubricate ng joint, bagaman limitado ang ebidensya para sa paggamit nito sa mga acute fractures. Ang mga platelet-rich plasma (PRP) injections ay gumagamit ng sarili mong blood components upang suportahan ang paggaling, ngunit magkakaiba ang resulta. Ang mga opsyon na ito ay hindi gamot; ito ay mga kasangkapan upang matulungan kang makilahok sa rehabilitation. Sinusuri namin ang iyong progreso nang regular upang malaman kung sapat na ang mga hakbang na ito o kung kailangan ng karagdagang mga hakbang.

Isinasalang-aling ang surgery kapag naabot na ng conservative care ang hangganan nito o kapag ang fracture ay masyadong kumplikado upang gumaling nang ligtas nang sarili. Inirerekomenda namin ang surgery para sa displaced fractures na may higit sa tatlong fragment, o kung ang buto ay nabasag (comminuted). Sa mga kasing ito, madalas naming palitan ang nasirang bahagi ng buto ng metal implant. Ang prosedurang ito ay ligtas at epektibo para sa mga unreconstructible fractures. Para sa mga pasyente na may malubhang kawalan ng katatagan ng siko (terrible triad injuries), maaari naming piliin na ayusin ang buto o palitan ito, depende sa kung alin ang nagbibigay ng pinakamatatag na joint. Ang radial head replacement ay nag-aalok ng sapat na functional results sa 96% ng mga pasyente sa long-term follow-up. Pinag-uusapan namin ang mga opsyong ito sa iyo upang matiyak na ang plano ay tugma sa iyong mga pangangailangan at layunin sa aktibidad.

Ano ang inaasahan

Ang iyong prognosis ay nakadepende sa laki ng seryosidad ng pagkabasag at kung may sugat sa ibang bahagi ng iyong siko. Para sa simpleng, matatag na fracture, ang non-surgical na paggamot ay karaniwang nagdudulot ng mahusay na long-term na resulta. Inaasahan mo ang mababang risk ng mga komplikasyon sa pamamagitan ng ganitong paraan. Kahit na ang iyong fragment ng buto ay bahagyang nasa maling posisyon ng 2 hanggang 5 mm, ang surgery ay madalas ay hindi nag-aalok ng karagdagang benepisyo kumpara sa pahinga at immobilization.

Kung ang iyong fracture ay kumplikado o nabasag-basag, ang iyong surgeon ay maaaring magrekomenda ng pagpapalit ng radial head gamit ang metal implant. Ang opsyong ito ay ligtas at epektibo para sa mga fracture na hindi naaayos gamit ang mga plate o screws. Karamihan sa mga pasyente na may mga implant na ito ay nakakamit ng magandang functional na resulta. Ang long-term na data ay nagpapakita na 96% ng mga pasyente ay may kasiyang-siya na mga resulta pagkatapos ng maagang pag-alis o pagpapalit ng radial head. Gayunpaman, dapat mong malaman na ang mga pagbabago sa pagkasira ay karaniwan sa mga X-ray pagkatapos ng ganitong prosedura. Sa kabila ng mga makikitang pagbabagong ito, ang iyong pang-araw-araw na function ay madalas ay nananatiling maganda.

Ang paggaling ay nararamdaman nang iba depende sa iyong treatment path. Sa conservative na pag-aalaga, ang mga sintomas ay karaniwang humihina habang ang buto ay gumagaling. Sa surgery, maaari kang maranasan ang post-traumatic arthritis sa paglipas ng panahon. Ito ay isang kilalang risk, ngunit hindi ito laging humahadlang sa iyong paggamit ng iyong braso nang maayos. Para sa mga malubhang sugat na kabilang ang maraming istruktura ng siko, ang pagpili sa pag-alis o pagpapalit ng radial head ay may katulad na epekto sa iyong final na resulta.

Karamihan sa ibang mga sugat na nakita sa MRI scans ay hindi symptomatic sa short term. Maaari kang hindi mo sila maranasan sa lahat. Ang iyong surgeon ay magpokus sa pangunahing fracture upang ibalik ang stability. Habang may ilang mga pasyente na maaaring kailanganin ang revision surgery sa hinaharap, ang karamihan ay nakakahanap ng kanilang paggaling na maaasahan. Layunin naming bigyan ka ng isang matatag na siko na nagbibigay-daan sa iyo na bumalik sa iyong mga normal na aktibidad. Ang iyong karanasan ay gabayin ng tiyak na kalikasan ng iyong sugat at kung gaano ito kumikilos sa piniling plano.

Kailan makipag-ugnayan sa isang doktor

Kumonsulta sa iyong doktor kung mayroon kang patuloy na sakit na hindi gumagaling kahit magpahinga, o kung nararamdaman mo ang kahinaan at kawalan ng katatagan sa iyong siko. Humingi ng pagsusuri ng espesyalista kung ang iyong siko ay nakakabit o biglang bumabagsak, o kung ang mga sintomas ay nakakaapekto sa iyong pagtulog o trabaho. Ang biglang paglala ng sakit ay dahilan din upang humingi ng medikal na tulong. Mahalaga ang maagang diagnosis dahil ang pagkaantala sa paggamot ay maaaring magdulot ng masamang resulta. Susuriin ng iyong surgeon ang mga senyales ng kawalan ng katatagan ng forearms, na nangangailangan ng angkop na paunang interbensyon. Ang maagang pagkilala ay tumutulong upang maiwasan ang mga komplikasyon at sumuporta sa mas magandang pangmatagalang resulta para sa iyong siko.

[L3] Overall reoperation rates are high in patients undergoing operative treatment of radial head and neck fractures. [35] (10.1177/1558944719837691)
[L3] Concomitant elbow fractures or dislocations do not affect the longer term outcomes of patients with unreconstructable radial head fractures requiring radial head arthroplasty. [36] (10.1016/j.jse.2017.06.031)
[L4] The management of acute unreconstructable fractures of the radial head in unstable elbow injuries with radial head replacement has a high risk of reoperation, with the peak risk appearing within 1 year after implantation. [37] (10.1097/corr.0000000000000876)
[L5] Most radial head fractures can be managed nonsurgically with early motion, while complex fractures associated with elbow instability require careful selection between open reduction and internal fixation and arthroplasty. [38] (10.5435/00124635-200707000-00003)
[L5] This study described the relationship between the coronoid and radial head, noting that the difference in radiographic height between the tip of the coronoid and anterior radial head in the normal elbow averages 5 mm. [39] (10.1016/j.jse.2021.05.025)
[L5] Nondisplaced and minimally displaced radial head fractures can be treated non-operatively with early mobilization. [41] (10.1530/eor-24-0035)
[L1] This study suggests that RHA is the best treatment of choice for efficacy and safety in the treatment of comminuted radial head fracture, while RHR is the safest choice to minimize postoperative complications and enable patients to perform all daily life activities. [42] (10.1007/s12306-020-00679-3)
[L4] The review aims to shed light into overlengthening as a complication of radial head replacement and to help identify and treat it. [47] (10.1007/s00402-020-03619-9)
[L5] The intraoperative decision to fix or replace the radial head is critical to optimize treatment outcomes. [49] (10.1016/j.hcl.2004.06.003)
[L4] The study shows a positive association between radiographic findings and patient symptoms for postoperative complications after radial head arthroplasty, validating radiography as the preferred postsurgical modality of imaging. [50] (10.2214/ajr.11.7674)
[L5] Radial head fractures should be viewed as osteoligamentous lesions rather than merely osseous lesions. [51] (10.1016/j.hcl.2015.06.003)
[L5] Radial head fractures are common with variable anatomy; treatment depends on fracture type and associated injuries, with conservative management for type 1, ORIF for type 2 with mechanical block, and arthroplasty or resection for type 3, particularly with ligamentous injury. [52] (10.1177/1758573219876921)
[L3] Anatomic radial head replacement has a risk of radiographic technical mistakes that correlate to poorer outcomes. [53] (10.1016/j.jseint.2026.101671)
[L4] ORIF and nonoperative treatment of isolated Mason type II radial head fractures provide comparably satisfactory functional outcomes, without significant differences. [54] (10.1016/j.jse.2020.10.011)
[L5] The ligaments have the most marked influence on stability, particularly when the upper limb is positioned such that valgus and varus gravity loads are applied to the elbow. [55] (10.1016/j.jse.2004.09.034)
[L5] The goals of current management are aimed at restoring normal anatomical and biomechanical function, with treatment dictated by fracture type, stability, and ligamentous integrity. [58] (10.1016/j.hcl.2007.01.009)
[L3] Our study demonstrates significant radiographic differences between two frequently used radial head arthroplasty implants. [60] (10.1097/bot.0000000000000876)
