Estabilizasyon Frakti Basen, Obligasyon Sikonferansyal, ak Senyen Entèn¶

Yon gwo enèji ka zo kase bag basen se youn nan blesi ki pi letal nan medikaman chòk, ki pote yon to mòtalite 15 a 50 pousan lè li akonpaye pa enstabilite emodinamik. Kontrèman ak yon zo long tankou shin oswa avanbra, basen imen an se yon bag zo rijid ki fòme ak de gwo zo innominate (ranch) ansanm devan nan senfiz pibik la ak ancrage nan do nan sakrum la pa ligaman ki pi fò nan kò a. Lè yon aksidan machin gwo vitès, kolizyon motosiklèt (kote basen an frape pi devan nan tank gaz la), pyeton grèv, blesi kraze, oswa tonbe soti nan yon wotè kraze bag sa a nan de kote epi chire ligaman sacroiliac dèyè yo, gon basen yo louvri tankou kouvèti yo nan yon liv (yon "liv louvri" ka zo kase basen).

As the bony pelvic ring springs open, its internal spherical volume expands dramatically, creating a massive retroperitoneal vacuum space that can swallow 3,000 to 5,000 milliliters (6 to 10 pints) of blood (the patient's entire circulating blood volume) without a single drop of blood appearing outside the skin. Worse still, well-meaning rescuers frequently kill pelvic trauma victims by pushing or rocking the hip crests to "test for a fracture" or by rolling the patient onto their side, which shatters fragile retroperitoneal blood clots. Knowing why you must never rock the pelvis, why a pelvic binder or improvised bedsheet must be centered strictly over the greater trochanters of the femurs (and never high up over the waist or iliac crests), and how to tie the knees and ankles in internal rotation closes the pelvic ring and saves lives.

4. **Aplike yon lyan pelvik komèsyal (SAM Pelvic Sling, T-POD, oswa Prometheus) oswa yon lisant dra ki pliye santre estrikteman sou GREATER TROCHANTER yo (boul zo yo sou kwis/ranch yo deyò), PA sou ren oswa krèt anch anwo a. pi gwo trokantè yo ak senfiz pibyen ogmante tèt femur yo anndan pou fèmen basen "liv louvri".
5. Gently rotate both legs inward ("pigeon-toed") and tie a figure-of-eight bandage or pad-and-strap around the knees and ankles. Because the ball of the thighbone (femoral head) sits inside the hip socket (acetabulum), turning the feet and knees inward uses the intact femurs as levers to pull the split halves of the pelvis together and stop them from flopping back open.
6. Keep the patient strictly NPO (nothing by mouth) and wrap them head-to-toe in warm blankets to prevent hypothermia and coagulopathy. Pelvic bleeding is primarily low-pressure venous and cancellous bone bleeding that relies on the patient's own clotting factors to tamponade; if the patient gets cold on the pavement, clotting enzymes shut down and internal bleeding becomes unstoppable.

Anatomy and pathophysiology: Why a broken pelvis can bleed out 5 liters of blood internally¶

1. Jeyometri yon esfè: Poukisa ouvèti basen an pa 5 santimèt kreye yon rezèvwa san jeyan.¶

Inside an intact adult pelvis, the bony ring encloses a compact hemispherical basin of roughly 1.5 liters (3 pints), tightly packed by tough parietal peritoneum and fascia. If a small blood vessel tears inside an intact pelvis, blood quickly fills that small, tight space until the pressure of the trapped blood equals the pressure inside the veins, naturally plugging the leak (self-tamponade).

However, in an open-book (APC) or vertical-shear pelvic fracture, the pubic symphysis rips open in front, the sacroiliac ligaments rip in back, and the tough pelvic floor fascia tears apart: * By the mathematical law of the volume of a sphere (\(V = \frac{4}{3}\pi r^3\)), every small increase in the radius (\(r\)) of the pelvic ring increases its internal volume by the cube of the radius. * If the front of the pelvis opens by just 5 centimeters (2 inches), the internal volume of the pelvic cavity jumps by more than 400 percent. * Even worse, once the fascial floor of the pelvis tears, blood is no longer confined to the pelvis: it tracks freely upward behind the abdominal lining into the vast retroperitoneal space all the way up to the kidneys and diaphragm. The retroperitoneum can hold 4,000 to 5,000 milliliters (8 to 10 pints) of blood before pressure builds high enough to slow down the bleeding, meaning an adult will bleed to death long before self-tamponade ever occurs.

2. The Three Sources of Pelvic Hemorrhage (and why a binder stops two of them)¶

Where does all that blood come from inside a broken pelvis? 1. The Presacral and Prevesical Venous Plexus (80% to 85% of cases): A dense, cobweb-like network of large, thin-walled, valveless veins plastered directly against the front of the sacrum and behind the pubic bone. When the sacrum or pubic bone cracks, hundreds of these veins are shredded simultaneously. 2. Spongy Cancellous Bone Marrow Surfaces: The flat iliac wings and sacrum are filled with vascular red bone marrow; the raw broken bone surfaces ooze briskly like a wet sponge. 3. Internal Iliac Artery Branches (10% to 15% of cases): High-pressure arterial tears (most commonly the superior gluteal artery where it hooks around the greater sciatic notch, or the internal pudendal and obturator arteries). * How a Pelvic Binder works: Wrapping a tight circumferential binder around the greater trochanters mechanically closes the split pelvic ring back to its normal small radius (restoring the retroperitoneal tamponade compartment), presses the raw bleeding bone surfaces directly against each other to stop marrow oozing, and splints the bone fragments so they cannot move and tear the venous clots during ambulance transport.

How to recognize a pelvic fracture without ever rocking the hips¶

Why "Pelvic Springing / Rocking" is strictly forbidden¶

For decades, old first aid textbooks taught rescuers to place their hands on both hip crests and push forcibly downward and outward ("rocking or springing the pelvis") to feel for grating bone (crepitus) or instability. Modern trauma guidelines (ATLS, PHTLS, CoTCCC, NICE, JRCALC) strictly forbid pelvic springing: * Manually pushing an unstable pelvic ring apart has sensitivity below 60 percent, causes excruciating pain, and actively kills patients by popping off the newly formed fibrin blood clots covering the torn sacral venous plexus. * Even in the hospital trauma bay, if a paramedic has already placed a pelvic binder based on the crash mechanism, trauma surgeons leave the binder closed until a CT scan or pelvic X-ray is taken.

Six safe, hands-off clues that point to a pelvic fracture¶

1. High-Energy Mechanism + Unexplained Shock: Any victim of a high-speed car crash, motorcycle crash, pedestrian strike, horse accident, crush injury, or fall from > 3 meters (10 feet) who has a rapid heart rate (tachycardia > 100 bpm), pale clammy skin, or confusion must be assumed to have a pelvic fracture until proven otherwise.
2. Pain Location (in conscious patients): Spontaneous pain in the hips, groin, pubic area, lower back (sacrum), or buttocks, or inability to lift either leg off the ground.
3. External Rotation or Shortening of the Lower Extremities: Look down at the victim's feet while they lie on their back. In an open-book pelvic fracture, one or both legs flop outward so the outer edge of the foot rests against the ground (external rotation). In a vertical shear fracture (or posterior hip dislocation), one leg looks 2 to 5 centimeters (1 to 2 inches) shorter than the other.
4. Urogenital and Perineal Signs (50% of severe pelvic fractures injure the bladder or urethra):
5. A drop of bright red blood at the tip of the penis or urethral opening (blood at the urethral meatus).
6. Dark purple bruising and swelling of the scrotum, labia, or perineum (Destot's sign).
7. Vaginal bleeding or rectal bleeding (which indicates an open pelvic fracture where a sharp pubic bone shard has punctured the vagina or rectum, carrying a catastrophic risk of both exsanguination and polymicrobial pelvic sepsis).
8. Retroperitoneal Flank Bruising: Bluish-purple bruising appearing along the flanks (Grey Turner's sign) or above the inguinal ligament (Fox's sign).
9. Gentle Single-Touch Palpation (Only if conscious and diagnosis is completely uncertain): If a conscious patient has a minor mechanism and you are unsure if the pelvis is injured, you may gently feel the front pubic bone and back of the hips with flat fingers to ask if it is tender, and if you ever perform a single stability check in a clinical setting, you only gently press inward (compressing toward the midline) once at the trochanters, NEVER pushing outward or downward.

Step-by-step technique: Applying a Commercial Pelvic Binder or Improvised Bedsheet Binder¶

Step 1: Prepare the patient and empty all pockets¶

1. Keep the patient lying completely flat on their back (supine).
2. Empty all pockets and remove belts: Before wrapping anything tightly around the hips, use trauma shears to cut away or empty everything inside the front, side, and back trouser pockets (smartphones, keys, thick wallets, coins, belt buckles, or tools). Tightening a pelvic binder over a set of keys or a phone in a pocket will drive the metal object into the skin over the bone, causing a full-thickness necrotic pressure ulcer within 60 minutes.

Step 2: Find the exact anatomical landmark: The Greater Trochanters¶

To find the greater trochanters on any patient: 1. Do not feel at the waist or the top curved rim of the hip bone (that is the iliac crest, which is 10 to 15 centimeters / 4 to 6 inches too high). 2. Instead, slide your gloved hands down the outside of the patient's upper thighs to the level of the pubic bone (crotch) in front and the widest part of the buttocks in back. You will feel a hard, knobby bony prominence on the outer side of each upper femur: that is the greater trochanter. 3. The center line of your pelvic binder or folded sheet must pass directly across both greater trochanters and across the pubic symphysis.

Step 3A: Applying a Commercial Pelvic Binder (SAM Pelvic Sling II, T-POD, or Prometheus)¶

1. Slide under the knees first (No-Lift Technique): Fold the binder flat and slide it through the natural hollow gap underneath the patient's knees (never lift or log-roll the pelvis).
2. Seesaw upward into position: Holding one end of the binder on each side of the patient, use a gentle side-to-side sawing motion to slide the binder smoothly up beneath the thighs and lower buttocks until it is centered directly over the greater trochanters.
3. Internally rotate the legs: Have a second rescuer hold the patient's ankles and gently bring the legs together while rotating the feet inward ("pigeon-toed").
4. Pull and lock:
5. For a SAM Pelvic Sling, pull the black strap firmly through the Autostop buckle while pulling the opposite handle in the counter-direction until the buckle clicks and the two steel prongs lock into the perforations (designed to lock automatically at exactly 150 Newtons / 33 pounds of circumferential tension so you cannot over-compress the pelvis), then press the Velcro strap down.
6. For a T-POD, trim the belt leaving a 15-to-20-centimeter (6-to-8-inch) gap over the front of the pelvis, attach the mechanical pulley system across the gap, and pull the drawcord until the gap narrows and the pelvis is snug, then lock the cord.

Step 3B: Applying an Improvised Bedsheet Pelvic Binder (When no commercial device is available)¶

A strong cotton bedsheet, wide drawsheet, or blanket folded smoothly is clinically proven to reduce pelvic volume just as effectively as a commercial binder if applied at the trochanters: 1. Fold the sheet smoothly: Fold a flat bedsheet lengthwise until it forms a smooth, wrinkle-free band roughly 15 to 20 centimeters (6 to 8 inches) wide. 2. Slide under the knees and seesaw up to the Greater Trochanters: Pass the folded sheet beneath the hollow of the knees and slide it carefully up beneath the buttocks until it is centered over the greater trochanters and pubic symphysis. 3. Bring the legs together in internal rotation: Have a helper hold the knees and ankles together with the toes pointed slightly inward. 4. Travèse, rale byen fèm, epi an sekirite: * Travèse de bout long fèy la sou devan senfiz pibyen an. * Avèk yon sèl sekouris sou bò gòch la ak youn sou bò dwat, apiye dèyè epi rale tou de bout fèy la san pwoblèm ak byen fèm nan direksyon opoze jiskaske kanson an pran moute ak fèy la byen anbrase trochanters yo. * Sekirize fèy la san pèdi tansyon: Swa tòde de pwent kwaze yo ansanm sou devan basen an epi kole yo ak kranpon chòk lou/emostat (oswa tòde yo alantou yon baton kout/baton epi kole baton an desann, oswa mare yon ne plat Reef/Kare sou yon sèvyèt ki plwaye pou pa fè sa).

Etap 4: Mare jenou yo ak je pye yo nan wotasyon entèn ("Mare nan figi-of-uit janm")¶

Menm ak yon lyan alantou ranch yo, pwa a lou nan de janm san konesans flopping aji kòm yon levye mekanik ki eseye pry senfiz la pibyen tounen louvri. 1. Mete yon sèvyèt ki plwaye, yon jakèt, oswa yon kousen kim ant jenou pasyan an ak ant cheviy yo pou anpeche maleng presyon po nan zo sou zo. 2. Vlope yon bandaj kravat triyangilè, yon bandaj roulo, oswa yon espageti lajè alantou tou de jenou, epi vlope yon pansman figi-uit alantou tou de cheviy ak pye pou kenbe janm yo alèz wotasyon anndan an.

Etap 5: Règ pou leve, chofe, ak transpò san danje¶

1. Pa janm woule yon pasyan ki kase basen: Lè paramedik yo rive pou yo deplase pasyan an sou yon brankè, yo pral sèvi ak yon scoop stretcher topedik (ki divize an mwatye nan longè e ki glise anba bò gòch ak bò dwat yo ak yon minimòm de mouvman) oswa yon 4-a-6 moun vètikal pon lift.
2. Pa janm retire oswa dekole yon lyan basen prematireman: Yon fwa yo aplike yon lyan basen, li rete fèmen an plas jiskaske pasyan an antre nan yon sant chòk lopital ak transfizyon san kouri ak ekip radyoloji òtopedik/entèvansyon pare. Detachman yon lyan basen nan jaden an pou "tcheke po a" pèmèt bag basen an prentan tounen louvri epi deklannche imedya re-senyen.
3. Rechofaj agresif: Kouvri pasyan an nèt ak dra cho ak yon baryè izolasyon anba yo pou anpeche Triyad Chòk Letal la (hypothermia, acidosis, and coagulopathy).

Special clinical scenarios in pelvic trauma¶

1. Louvri Frakti Basen ak Lacerasyon Perineal / Rektal / Vajen¶

Roughly 5 percent of pelvic ring fractures are open pelvic fractures, in which a razor-sharp fragment of the pubic rami or ischium slices through the skin of the groin, perineum, buttocks, vagina, or rectum. Open pelvic fractures carry a mortality rate approaching 40 to 50 percent because external skin tamponade is lost and fecal bacteria contaminate the retroperitoneal hematoma: * Never pull apart the legs or hips to inspect a perineal wound if it means opening the pelvic ring. * Control external groin or perineal bleeding with firm direct pressure and hemostatic gauze wound packing (or a junctional inguinal compression device if available), then apply the circumferential pelvic binder over the greater trochanters right over the packed wound dressing. * Never insert a urinary catheter, rectal thermometer, or vaginal pack in the field if blood is visible at the urethral meatus or perineum, as the urethra or rectum may be partially transected.

2. Pelvic Fractures in Pregnancy and in Children¶

• During Pregnancy: In the second and third trimesters, the gravid uterus rises out of the bony pelvis into the abdomen, and maternal uterine blood flow reaches 600 to 800 milliliters per minute. You can and should still apply a pelvic binder to an unstable pelvic fracture in a pregnant patient because the binder sits low over the greater trochanters and pubic symphysis (below the main fundus of the uterus). After applying the trochanteric binder, manually displace the pregnant uterus 15 to 20 degrees to the LEFT (or tilt the rigid scoop stretcher 15 to 30 degrees to the left) so the heavy uterus does not crush the maternal inferior vena cava (supine hypotensive syndrome).
• In Children: Pediatric pelvic bones are flexible and lined with thick cartilage, so it takes extreme kinetic energy (such as being run over by a vehicle) to break a child's pelvic ring. Fold a smaller sheet or pediatric binder to match the width of the child's trochanters and monitor closely for concurrent spleen or liver hemorrhage.

3. Prehospital Handoff Checklist for EMS and Trauma Resuscitation¶

• Mechanism of injury: High-speed crash, motorcycle fuel-tank impact, fall height, or crush weight.
• Tan egzak ak nivo anatomik nan plasman lyan: Konfime lyan an santre sou pi gwo trokantè yo e ke pòch yo te vide anvan yo sere.
• Distal neurovascular (PMS) status in both feet: Dorsalis pedis and posterior tibial pulses, skin warmth, and foot movement before and after binding.
• Urogenital signs observed: Presence of blood at the urethral tip, scrotal/labial hematoma, or perineal lacerations.

Knowing how to recognize a hidden pelvic fracture and apply a trochanteric binder turns an otherwise fatal internal bleed into a survivable injury. Consider taking a certified first aid, Stop the Bleed, or prehospital trauma course through your national Red Cross or Red Crescent society, St John Ambulance, or the National Association of Emergency Medical Technicians (NAEMT).
