Hip Disorders
This condition involves abnormal contact between the femoral head and acetabulum, commonly found in athletes and diagnosed with FADIR testing.
What is femoroacetabular impingement (FAI)?
This is the most reliable early clinical sign of compartment syndrome.
What is pain out of proportion to the injury?
A 12-year-old girl has anterior knee pain with no trauma and popping during activity. This common diagnosis is suspected.
What is patellofemoral syndrome (PFS)?
The most commonly fractured bone in the human body.
What is the clavicle?
This hip condition often requires surgery only if conservative measures fail and the patient is symptomatic with mechanical symptoms.
What is femoroacetabular impingement (FAI)?
Lateral hip pain with pain on palpation over the greater trochanter, pain while lying on the side, and Trendelenburg gait suggests this syndrome.
What is Greater Trochanteric Pain Syndrome (GTPS)?
This open fracture classification includes wounds >10 cm or those with vascular injury.
What is Gustilo-Anderson Type III?
This special test is most sensitive for detecting ACL tears.
What is Lachman’s test?
This part of the humerus is most likely to cause axillary nerve injury when fractured.
What is the proximal humerus?
DOUBLE JEOPARDY
This proximal thigh injury may require surgery if >2 tendons are torn with >2cm retraction.
What is proximal hamstring rupture?
This intraosseous condition results from compromised blood flow to the femoral head and can show a “crescent sign” on imaging.
What is avascular necrosis (osteonecrosis) of the hip?
This imaging finding may indicate an open fracture if seen near a fracture site.
What is subcutaneous air on radiograph?
This knee injury presents with lateral joint line tenderness, swelling, and a positive McMurray’s test with an audible “click” during internal rotation and varus stress. The patient may also describe mechanical symptoms like locking.
What is a lateral meniscus tear?
This fracture pattern in the wrist involves dorsal displacement and is named after an early 1800s surgeon.
What is a Colles fracture?
This knee fracture is often treated non-operatively unless it disrupts the extensor mechanism.
What is a patella fracture?
This hip condition may present with a positive clamshell test and tenderness over the adductors, often in soccer and hockey players.
What is an adductor injury?
Initial management of a suspected open fracture includes this key pharmacologic step, even before surgery.
What is early IV antibiotic administration?
The “J sign” on knee exam refers to abnormal movement of this structure.
What is the patella?
Radial head fractures follow the “rule of 3s.” Name one of the three criteria.
What is <30° angulation, <3mm step-off, or <1/3 articular surface involvement?
This fracture requires urgent vascular assessment due to its high association with arterial injury from tethering.
What is distal femur fracture?
This anterior hip pathology presents with groin pain and can result from overuse, especially in distance runners; early MRI is essential for diagnosis.
What is a stress fracture of the hip?
A compartment pressure within this threshold of diastolic BP is considered diagnostic for compartment syndrome.
What is within 30 mmHg?
MCL and LCL injuries are tested with valgus and varus stress at these degrees of knee flexion.
What are 0 and 30 degrees?
A Monteggia fracture involves the ulna shaft and instability of this joint.
What is the proximal radioulnar joint (PRUJ)?
Nonoperative treatment of tibial plateau fractures is possible if the joint is stable and these three criteria are met.
What are <5mm condylar widening, <3mm step-off, and <5° valgus deformity?
