HEENT : No pale conjunctiva, anicteric sclera HEART : Full regular pulse, normal s1 s2 no murmur LUNGS : Clear equal both lungs, no adventitious sound ABDOMEN : No distension, normoactive bowel sound, soft, not tender
EXT. : as picture
Inspection : Rt. Hip – flexion & adduction & internal rotation
Abrasion wound at Lt. knee Palpitation : Tender at Rt. Hip Range of motion : limit ROM of Rt. Hip Neurovascular : Normal sensation, can dorsiflexion and plantar flexion DPA 2+
FILM BOTH HIP AP
DIAGNOSIS # Posterior Right hip dislocation # Mild head injury (Moderate risk)
(POSTERIOR) HIP DISLOCATION
OUTLINE Epidemiology Anatomy Classification Presentation Imaging Management Complications
EPIDEMIOLOGY RARE ! Most commonly dislocated joint of the lower extremity, with incidence of 5.2% Male : Female = 4 : 1 Mechanism is usually young patients with high energy trauma
ANATOMY
BLOOD SUPPLY
EMERGENCY CONDITION !!
Multiple traumaAvascular necrosis
TYPE Simple : pure dislocation without associated fracture
Complex : dislocation associated with fracture of acetabulum or proximal femur
ANATOMIC CLASSIFICATION Posterior dislocation (90%) occur with axial load on femur, typically with hip flexed and adducted axial load through flexed knee (dashboard injury)
Anterior dislocation (10%) occurs with the hip in abduction and external rotation
Central dislocation caused by a lateral force against an adducted femur always a fracture-dislocation
PRESENTATION Symptoms : acute pain, deformity, inability to move the hip joint, inability to bear weight
Physical exam : HIP >>> flexion, adduction, and internal rotation examine knee for associated injury or instability neurovascular exam (10-20% sciatic nerve injury)
SCIATIC NERVE Common peroneal (fibular) nerve Sensation : lateral side of the lower leg and upper surface of the foot
Motor : dosiflexion
Tibial nerve Sensation : sole of the foot Motor : plantar flexion
IMAGING Radiographso Shenton's line brokeno femoral head smaller than contralateral sideo lesser trochanter shadow reveals internally rotated limb as compared to contralateral side
IMAGING CTpost reduction CT must be performed for all traumatic hip dislocations to look for femoral head fractures, loose bodies, acetabular fractures
MANAGEMENTNon-operative : Emergent closed reduction within 6 hr
Allis maneuver Stimson maneuver Bigelow maneuver
Operative
ALLIS MANEUVER
STIMSON MANEUVER
contraindicated in the setting of thoracoabdominal trauma or a difficult airway.
BIGELOW MANEUVER
OPERATIVE Indications• Irreducible dislocation (approximately 10% of all dislocations)• Persistent instability of the joint following reduction (eg, fracture-dislocation of the posterior acetabulum)• Fracture of the femoral head or shaft• Neurovascular deficits that occur after closed reduction
COMPLICATIONS Post-traumatic arthritis up to 20% for simple dislocation, markedly increased for complex dislocation If an associated acetabular fracture is present, the incidence of traumatic arthritis is as high as 80%.
Femoral head osteonecrosis 5-40% incidence Increased risk with increased time to reduction
Sciatic nerve injury 8-20% incidence associated with longer time to reduction
Recurrent dislocations less than 2% Risk factors for recurrent dislocation are large capsular defects, intra-articular fragments, or a prosthetic hip.
MANAGEMENT IN THIS PATIENT CT Brain non-contrast Set OR for close reduction under GA Test stability 30, 60, 90 Repeat film after reduction Repeat neurovascular examination On skin traction 2 kg.
