Na-dislocate na balikat, kneecap, o joint immobilization clinical first aid¶

Ang isang kumpletong joint dislocation (luxation) ay nangyayari kapag ang matinding mekanikal na puwersa ay napunit ang fibrous joint capsule at supporting ligaments, na nagtutulak sa articular ends ng dalawang buto na ganap na hindi nagdikit sa isa't isa. Ang bahagyang dislokasyon (subluxation) ay nag-iiwan sa magkasanib na mga ibabaw na bahagyang magkadikit ngunit hindi maayos. Hindi tulad ng isang mid-shaft bone fracture kung saan ang pinsala ay nasa isang tuwid na silindro ng buto, ang magkasanib na dislokasyon ay nangyayari sa mismong masikip na anatomical tunnel kung saan ang mga pangunahing arterya at peripheral nerve ay tumatawid mula sa isang bahagi ng paa patungo sa susunod.

Dahil ang displaced bone head ay kadalasang direktang nakapatong sa isang pangunahing daluyan ng dugo o nerve trunk, na sinamahan ng hindi kilalang nakatagong articular fractures, pagtatangkang hilahin, i-twist, o "i-pop" ang isang dislocated joint pabalik sa lugar sa field ay isa sa mga pinakamapanganib na pagkakamali sa trauma care. Alam kung paano magsagawa ng 30-segundong distal Circulation, Sensation, and Motor (CSM) check, kung paano makilala ang tunay na limb-threatening vascular emergency (tulad ng dislokasyon ng kasukasuan ng tuhod o dislokasyon ng balakang) mula sa lateral kneecap slip, at kung paano i-immobilize ang bawat dislocated joint nang mahigpit sa unan-nakalagay na posisyong matatagpuan sa nerbiyos- function.

Gawin ito ngayon¶

1. Sabihin sa nasugatan na manatiling ganap na tahimik at manu-manong suportahan ang kanyang paa sa eksaktong anggulong hinahawakan nila. Huwag kailanman subukang ituwid ang isang nakatungo na dislocate na tuhod, siko, o balakang, at huwag subukang itulak ang isang dinukot na dislocate na balikat na patagilid sa ribcage.
2. Huwag subukang hilahin, i-twist, o "i-pop" ang isang na-dislocate na joint pabalik sa socket nito. Hanggang 25 hanggang 40 porsiyento ng joint dislocations ay may kaakibat na bali sa loob ng joint socket; Ang paghila sa paa nang walang X-ray at pagpapahinga ng kalamnan ay maaaring direktang magmaneho ng mga tulis-tulis na gilid ng buto sa pamamagitan ng mga pangunahing arterya at nerbiyos.
3. Suriin kaagad ang distal na Circulation, Sensation, and Motor (CSM) na function sa ibaba ng nasugatang joint. Palpate ang radial pulse sa pulso (para sa mga pinsala sa balikat o siko) o ang dorsalis pedis at posterior tibial pulse sa paa (para sa mga pinsala sa balakang, tuhod, o bukung-bukong), pindutin ang isang kuko o daliri sa paa2 muling pagpuno ng balat ** sekundaryong pag-refill ng mga kuko ng daliri sa paa**, at suriing muli ang kulay rosas na sensasyon ng daliri sa paa** o paggalaw ng daliri ng paa.
4. Tawagan kaagad ang iyong lokal na emergency na numero kung ang kamay o paa sa ibaba ng dislokasyon ay maputla, asul, malamig, manhid, o walang pulso, o para sa anumang balakang, kasukasuan ng tuhod, siko, o bukas na dislokasyon. I-dial ang 911 sa United States at Canada, 112 sa buong European Union, 999 sa United Kingdom, 000 sa Australia, o tingnan ang direktoryo ng mga numerong pang-emergency.
5. Agad na tanggalin ang lahat ng singsing, relo, bracelet, sapatos, at masikip na manggas o pantalon mula sa nasugatang paa. Ang mga magkasanib na dislokasyon ay nagdudulot ng mabilis na intra-articular hemarthrosis (pagdurugo sa magkasanib na espasyo) at distal venous swelling na maaaring gawing ischemic tourniquet ang mga singsing o bota sa loob ng 20 minuto.
6. I-pad ang bakanteng espasyo sa ilalim ng deformed joint at i-splint ito nang mahigpit sa posisyon na natagpuan, pagkatapos ay lagyan ng tela na nakabalot na ice pack. Gumamit ng mga naka-roll na tuwalya, kumot, unan, o isang moldable na SAM splint na nakabaluktot upang tumugma sa eksaktong deformity, i-secure ito sa itaas at ibaba ng joint nang hindi tinatali ang mga strap nang direkta sa ibabaw ng buto ng pasyente, walang nakausli na buto ng pasyente, ** walang nakausli na buto ng pasyente (**) at maglagay ng cool pack sa loob ng 15 hanggang 20 minuto sa isang pagkakataon.

Paghahambing ng mga pangunahing anatomical joint dislocation at ang kanilang mga neurovascular traps¶

Ang bawat pangunahing kasukasuan sa katawan ay may isang tiyak na direksyon kung saan ito ay kadalasang nadidislocate, na gumagawa ng isang klasikong pustura ng paa at nagbabanta sa isang partikular na ugat o arterya na direktang tumatakbo sa magkasanib na kapsula.

Why you must never try to "pop" a dislocated joint back in¶

In action movies and sideline sports myths, someone invariably grabs a dislocated arm or finger, yanks hard on it, and pops it back into place so the hero can keep going. In real clinical medicine, layperson attempts to reduce a dislocation without radiographs and analgesia frequently cause permanent disability:

1. Up to 40 percent of dislocations contain hidden intra-articular fractures: When a shoulder, elbow, ankle, or finger dislocates, the impact frequently shears off a piece of the joint socket or bone head (for example, a greater tuberosity fracture or bony Bankart fracture in the shoulder, a coronoid process or radial head fracture in the elbow, or a malleolar fracture in the ankle). Yanking on the limb grinds sharp fracture fragments across articular cartilage and can convert a closed injury into an unstable comminuted fracture.
2. Nerves and arteries can be looped around the displaced bone head: During a dislocation, the brachial artery, sciatic nerve, axillary nerve, or median nerve is often stretched taut over the neck of the displaced bone. Pulling or levering the bone forcefully without anatomical technique can trap the nerve or artery inside the joint space or shear the blood vessel wall (intimal tear), causing acute arterial thrombosis and limb loss.
3. Violent protective muscle spasm defeats brute force: Within minutes of a dislocation, the large muscles crossing the joint (such as the deltoid, pectoralis major, quadriceps, or hamstrings) lock into an involuntary protective tetanic spasm. Trying to overpower spasming muscles in an awake, unmedicated person requires dangerous mechanical force that can snap the humerus shaft or tear the rotator cuff completely.

Step 1: Performing the Distal CSM (Circulation, Sensation, Motor) Check¶

Whenever you encounter a suspected dislocation or fracture, you must assess and record the Distal CSM status (also called PMS: Pulse, Motor, Sensation) before you apply a splint AND immediately after you tie the last splint strap. If a splint is tied too tightly or shifts the bone slightly, checking CSM afterward catches the problem immediately so you can loosen the straps.

How to check CSM in the Upper Extremity (Shoulder, Elbow, Forearm, Wrist)¶

Paano suriin ang CSM sa Lower Extremity (Hip, Knee, Patella, Ankle)¶

Step-by-step immobilization for specific dislocated joints¶

The golden rule of prehospital dislocation care is "Splint it in the position found by bringing the padding to the limb, never forcing the limb to the splint."

1. Dislocated Shoulder (Glenohumeral Joint)¶

Roughly 95 percent of shoulder dislocations are anterior dislocations (the head of the humerus pops forward out of the shallow glenoid socket and rests beneath the coracoid process), while 4 percent are posterior dislocations (triggered by seizures, electric shocks, or a blow to the front of the shoulder).

• Why a standard flat arm sling hurts an anterior shoulder dislocation: In an anterior dislocation, the displaced humeral head locks the arm slightly away from the side of the body (abducted 15 to 30 degrees). Trying to push the person's elbow flat against their ribs to fit into a standard tight sling levers the humeral head against the glenoid rim and axillary nerve, causing excruciating pain.
• The Pillow-and-Sling Technique (Step-by-Step):
• Have the patient sit upright or semi-reclined while a helper supports their bent forearm in the exact angle they are holding it.
• Take a soft bed pillow, folded fleece jacket, or thick rolled blanket and gently tuck it into the open triangular gap between the injured inner arm/elbow and the side of the ribcage. This fills the dead space so the arm can rest in its natural abducted position without being pushed inward.
• Drape a large triangular bandage (arm sling) under the forearm and around the back of the neck, tying the knot to the side of the neck (never directly over the cervical spine bones) and placing soft padding under the neck strap.
• Tie a broad horizontal swathe bandage around the outside of the injured arm, over the pillow, and around the opposite side of the chest to stop the arm from swinging forward or backward during ambulance transport.
• Check the radial pulse and the "regimental badge" patch of skin over the outer deltoid muscle every 15 minutes.

2. Dislocated Kneecap (Lateral Patellar Dislocation) vs. True Knee Dislocation¶

Distinguishing these two knee injuries takes only a gentle visual inspection after slicing open the trouser leg:

• Lateral Patellar (Kneecap) Dislocation:
• How to recognize it: The person twisted their leg on a planted foot; the knee is locked in a partially bent (flexed) position, the front of the knee looks flat or concave, and the rounded kneecap is visibly sitting on the outer (lateral) side of the knee. Foot pulses and toe movement are completely normal.
• First aid protocol: Do not try to push the kneecap back across the joint, and do not force the bent knee straight. Have the person sit or lie down, slide a thick rolled pillow or folded blanket underneath the bent knee so the leg rests comfortably on the pillow without any muscle strain, wrap a loose bandage or straps around the pillow and leg to stabilize it, apply a cloth-wrapped ice pack over the side of the knee for 15 minutes, and transport to the hospital.
• True Knee Joint (Tibiofemoral) Dislocation:
• How to recognize it: The entire lower leg (tibia) is shifted forward, backward, or sideways off the end of the thighbone (femur), OR the person suffered a severe hyperextension/twisting knee injury that "popped out and popped back in" leaving a grossly unstable, rapidly ballooning knee.
• First aid protocol: Treat every suspected tibiofemoral dislocation as an immediate vascular emergency. Call 911/112/999 immediately, check the dorsalis pedis and posterior tibial foot pulses, pad underneath the exact angle of the knee with rolled towels, immobilize from the upper thigh to the ankle using two padded board or SAM splints tied along the inner and outer sides of the leg, and arrange immediate hospital transport for a CT angiogram (CTA) or Ankle-Brachial Index (ABI) check.

3. Dislocated Elbow (Ulnohumeral Joint) and Toddler's Nursemaid's Elbow¶

• Adult or older child Elbow Dislocation: Because the brachial artery runs inches in front of the elbow joint crease, an elbow dislocation can cut off blood flow to the forearm within minutes, leading to Volkmann ischemic contracture (permanent claw-like paralysis of the hand).
• Never bend or straighten a dislocated elbow: If the elbow is locked at a 45-degree angle or stuck nearly straight, leave it at that exact angle.
• Splinting: Take a malleable SAM splint or padded cardboard strip, bend it on your own uninjured arm to match the exact angle of the victim's deformed elbow, pad the inside generously with soft gauze, and secure it along the back or side of the upper arm and forearm using roller gauze. Never wrap tape tightly across the front crease of the elbow (the antecubital fossa), as swelling there will compress the brachial artery.
• Toddler's Nursemaid's Elbow (Radial Head Subluxation):
• How to recognize it: Occurs almost exclusively in children aged 1 to 4 years after an adult pulls up on the child's hand to stop a fall, swings them by the arms, or pulls their arm through a jacket sleeve. There is no swelling, no bruising, and no visible deformity, and the child is calm until someone tries to bend their elbow or turn their palm upward. The toddler holds the arm slightly bent against their tummy with the palm facing downward or inward.
• First aid protocol: Do not try to manipulate the toddler's arm at home (especially if the child actually fell onto the arm, which can cause a supracondylar elbow fracture that looks identical). Support the child's arm comfortably against their chest with a soft scarf sling and take them to an urgent care clinic or emergency department, where a clinician can reduce the slipped annular ligament in 3 seconds without sedation, after which the child typically reaches for a toy within 10 minutes.

4. Dislocated Hip (Posterior vs. Anterior)¶

A traumatic dislocation of the native hip joint requires tremendous kinetic energy (such as a motor vehicle collision, being struck as a pedestrian, or falling from a roof), whereas patients with an artificial total hip replacement (prosthesis) can dislocate their prosthetic hip simply by bending low to tie a shoe, crossing their legs, or sitting in a low chair.

• Time is bone (The 6-Hour Avascular Necrosis Window): In a native hip dislocation, the delicate retinacular arteries feeding the ball of the thighbone (femoral head) are kinked and stretched shut. If a dislocated native hip is not reduced in the hospital within 6 hours, the rate of avascular necrosis (osteonecrosis / bone death of the femoral head) jumps from roughly 5 percent to over 50 percent, destroying the hip joint permanently.
• First aid protocol: Call emergency medical services immediately. Keep the patient lying on their back on the floor or stretcher, slide thick rolled blankets and pillows underneath the bent, inwardly rotated knee and between the two thighs to support the leg in the exact posture found, check foot pulses and big-toe dorsiflexion (sciatic nerve check), and keep the patient strictly NPO (nothing by mouth) for hospital procedural sedation.

5. Dislocated Finger or Thumb (Interphalangeal / Metacarpophalangeal Joints)¶

Fingers frequently dislocate backward (dorsally) at the middle knuckle (PIP joint) when struck on the tip by a basketball, baseball, or football ("coach's finger").

• First aid protocol:
• Remove all rings from EVERY finger on the injured hand within the first 60 seconds: Even if only the ring finger is dislocated, swelling spreads across the back of the hand within minutes. If a ring is already tight, lubricate the finger heavily with soap, cooking oil, or window cleaner and wind dental floss or string distally-to-proximally if needed, or cut the ring off before ischemia sets in.
• Do NOT pull on a dislocated finger on the sports sideline: Many dorsal PIP dislocations involve an avulsion fracture of the volar plate or an entrapped tendon (boutonniere or complex MCP dislocation); pulling on the finger can buttonhole the bone head through the palmar ligaments so tightly that it can only be freed in the operating room.
• Splint sa posisyon na nakita: Maglagay ng maliit na roll ng gauze sa palad ng kamay upang ang mga daliri ay magpahinga sa natural na kurba, o maghulma ng isang padded aluminum finger splint upang tumugma sa eksaktong baluktot na anggulo ng dislocated na daliri, i-tape ito nang dahan-dahan (hindi kailanman masikip nang pabilog), itaas ang kamay sa itaas ng antas ng puso sa mga unan, at lagyan ng isang dry pack na tela.

Bakit kailangan mong panatilihing NPO ang pasyente (walang makakain o maiinom)¶

Sa tuwing ang isang tao ay may na-dislocate na balikat, siko, balakang, tuhod, o bukung-bukong, huwag silang bigyan ng anumang pagkain, tubig, inuming pampalakasan, o mga tabletas para sa sakit sa bibig na lunukin kasama ng isang basong tubig habang naghihintay ng ambulansya o nagmamaneho papunta sa emergency department:

• Ang pagbabawas ng isang malaking joint dislocation sa emergency department ay nangangailangan ng intravenous procedural sedation at analgesia (gamit ang mga gamot tulad ng propofol, ketamine, etomidate, o fentanyl) upang ang pasyente ay hindi makaramdam ng pananakit at ang malalakas na kalamnan na nakapalibot sa joint ay ganap na nakakarelaks.
• Kung ang pasyente ay nakainom kamakailan ng tubig o kumain ng pagkain, ang malalim na sedation ay nagdudulot ng panganib na muling mag-regurgitate ang mga nilalaman ng tiyan sa mga baga (pulmonary aspiration), na maaaring makapagpaantala sa pagbabawas ng emergency room o nangangailangan ng ultrasound-guided intra-articular nerve block sa halip.

Binibigyang-daan ka ng mga kasanayan sa first aid na protektahan ang mga vulnerable na arterya at nerbiyos pagkatapos ng magkasanib na pinsala, ngunit ang hands-on na pagsasanay ay napakahalaga. Pag-isipang kumuha ng sertipikadong first aid o kursong first responder sa kagubatan sa pamamagitan ng iyong pambansang Red Cross o Red Crescent na lipunan, St John Ambulance, o isang lokal na sentro ng pang-emerhensiyang medikal na pagsasanay upang magsanay ng splinting at neurovascular check sa isang instruktor.
