Femoral head fracture: overview

A femoral head fracture is a break in the ball of the hip joint. It is uncommon and usually follows high-energy trauma, especially a motor-vehicle collision, often with a hip dislocation. This is different from a femoral neck fracture, which is a break just below the femoral head and uses different classifications and treatment decisions.

Treat a suspected fracture-dislocation as an orthopedic emergency because prolonged dislocation can compromise the head's blood supply and raise the risk of avascular necrosis (AVN).

Initial priorities and admission

These patients should generally be admitted urgently under orthopedic trauma care, often after ED trauma-team assessment.

ATLS assessment first
- Identify head, chest, abdominal, pelvic, and other limb injuries.
- High-energy injury frequently causes associated trauma.
Record neurovascular status before and after reduction
- Pulses, capillary refill, motor function, sensation.
- Pay particular attention to the sciatic nerve, especially peroneal division function: ankle/toe dorsiflexion and sensation in the first dorsal web space.
Analgesia, IV access, NPO, DVT prophylaxis as appropriate
- Avoid repeated forceful reduction attempts.
Urgent reduction if the hip is dislocated
- A dislocated hip with femoral-head fracture should be reduced as soon as safely possible, typically aiming for within 6 hours of injury when feasible.
- Reduction is usually attempted under adequate procedural sedation or general anesthesia by an experienced clinician with orthopedic involvement.
- Irreducible dislocation, an incarcerated fragment, instability, or worsening neurologic deficit needs urgent open reduction.

A native hip fracture-dislocation requires hospital admission and urgent orthopedic review, rather than routine discharge from the ED. Rosen's Emergency Medicine states that these patients should be admitted for operative management.

Diagnosis

History and examination

Typical findings:

Major trauma, classically dashboard impact with the hip flexed
Severe hip or groin pain and inability to bear weight
Markedly restricted movement
Limb position can suggest the direction of dislocation:
- Posterior dislocation: hip flexed, adducted, internally rotated
- Anterior dislocation: hip abducted and externally rotated
Check for knee injury, femoral shaft fracture, acetabular injury, and sciatic or femoral nerve injury.

Imaging sequence

Study	Role
AP pelvis and AP/lateral hip X-rays	First-line study. Shows dislocation, gross fragment, femoral neck or acetabular fracture.
CT hip/pelvis with thin cuts and 3D reconstructions	Essential after reduction in nearly all cases. Defines fragment size, location, rotation, residual step-off, loose intra-articular fragments, congruency, and acetabular fracture.
MRI	Not routine in the acute phase. Consider if occult fracture, cartilage/labral injury, or later suspected AVN is a concern.

After closed reduction, repeat AP pelvis X-ray immediately, then CT. An asymmetric joint space or non-concentric reduction can indicate an entrapped osteochondral fragment.

As summarized in Miller's Review of Orthopaedics, use radiographs initially and CT to define fragment location/size and exclude associated acetabular fracture. Miller's Review of Orthopaedics, p. 919.

Classification: Pipkin classification

The most used classification is Pipkin. It describes femoral-head fracture-dislocations.

Pipkin type	Definition	Clinical relevance
I	Fracture inferior (caudal) to the fovea capitis	Usually a smaller fragment outside the main weight-bearing dome
II	Fracture superior (cephalad) to the fovea	Involves the weight-bearing part of the head, so joint congruity is more important
III	Type I or II plus an ipsilateral femoral neck fracture	Severe injury with high AVN risk. Usually needs urgent surgery
IV	Type I or II plus an acetabular fracture, commonly posterior wall	Treat based on femoral-head congruity and acetabular stability

$Pipkin type I femoral head fracture$

The Pipkin summary distinguishes Type I as below the fovea and Type II as above it in the weight-bearing region.

Displaced versus nondisplaced: how it is assessed

“Displaced” is not based on X-ray appearance alone. The key assessment is on post-reduction CT.

Nondisplaced / acceptable reduction

Generally means:

Hip is concentrically reduced
Articular surface is congruent
No loose intra-articular fragment
No fragment rotation
No meaningful articular step or gap
Stable through a gentle examination under anesthesia, when indicated

For femoral-head injuries, a commonly used practical threshold is less than 1 mm articular step-off, though clinical decisions also depend on fragment size, location, cartilage damage, stability, and associated injury.

Displaced / unacceptable reduction

Concerning features include:

Articular step-off greater than 1 mm
Fragment displacement or rotation
Nonconcentric hip reduction
Loose body within the joint
Large Type I fragment or any Type II fragment affecting the weight-bearing dome
Hip instability after reduction
Associated femoral neck or unstable acetabular fracture

Miller's Review of Orthopaedics lists more than 1 mm step-off, loose bodies, and associated neck or acetabular fractures requiring surgery as operative indications. Miller's Review of Orthopaedics, p. 919.

Management by injury pattern

1. Hip dislocation with no major residual fracture displacement

Treatment

Urgent closed reduction
Post-reduction CT
Serial neurovascular checks
Protected weight bearing and close imaging follow-up

This may be appropriate for:

Small Pipkin I fragment with a congruent stable joint
Nondisplaced Type I injury
Carefully selected nondisplaced Type II injury

2. Small Pipkin I fragment

Possible management options

Nonoperative care if fragment is small, hip is congruent/stable, and there is no loose body.
Arthroscopic or open fragment excision may be considered if the fragment is small but displaced, impinges, or is an intra-articular loose body.
Fixation if it is a large fragment, contributes to stability, or affects joint congruity.

3. Pipkin II fracture

Because this involves the weight-bearing femoral-head surface, anatomic restoration is more important.

Typical approach

Nondisplaced and congruent: selected cases can be treated nonoperatively with strict surveillance.
Displaced, rotated, or step-off greater than about 1 mm: open reduction and internal fixation (ORIF) is usually preferred, commonly with countersunk headless compression screws.

4. Pipkin III fracture: femoral head plus femoral neck fracture

This is a severe injury.

Management

Urgent orthopedic trauma surgery.
In younger patients, attempt head-preserving surgery with anatomic reduction and fixation when feasible.
In older patients, or when head/neck damage is non-reconstructible, acute total hip arthroplasty may be more appropriate.
AVN and later arthritis risk are particularly high.

5. Pipkin IV fracture: femoral head plus acetabular fracture

Management

CT-based operative planning.
ORIF of the posterior wall/acetabular fracture if unstable or displaced.
Fixation or excision of the femoral-head fragment depending on its size, weight-bearing involvement, and congruity.
Surgical approach depends on which injury needs treatment most, often posterior for posterior-wall acetabular injury.

Time course and typical durations

Exact timing varies with fracture pattern, operation, associated injuries, and surgeon protocol.

Time point	Usual action
Immediately to 6 hours	Resuscitation, X-rays, neurovascular examination, urgent reduction of dislocated hip.
Same day, after reduction	CT to confirm concentric reduction and assess fragment, step-off, loose body, femoral neck, and acetabulum.
Within 24-48 hours	Definitive surgery if needed, depending on patient stability, soft tissues, operating access, and associated injuries. Irreducible or unstable injuries may need emergency surgery sooner.
Hospital stay	Often 1-3 days after uncomplicated reduction/observation; approximately 2-5 days or longer after ORIF, arthroplasty, polytrauma, or complications.
First 4-6 weeks	Protected or toe-touch/partial weight bearing is common for nonoperative femoral-head fracture management.
6 weeks	Clinical and X-ray review. If healing and fixation are stable, gradual progression of weight bearing may begin.
8-12 weeks	Many patients progress toward full weight bearing if radiographic union and pain permit. Complex acetabular or neck injuries may need longer protection.
3, 6, 12 months and longer	X-ray follow-up for union, joint congruity, heterotopic ossification, post-traumatic arthritis, and AVN. MRI may be used if persistent pain raises concern for AVN.

For selected nondisplaced Type I or II injuries, Miller's Review of Orthopaedics recommends protected weight bearing for 4-6 weeks. For nonoperatively managed Type II injuries, it also recommends frequent, often weekly, radiographs for the first 3-4 weeks to detect secondary displacement. Miller's Review of Orthopaedics, p. 919.

Rehabilitation

Rehabilitation is individualized but usually includes:

Early ankle pumps, DVT prevention, bed mobility, and transfers
Gentle hip range-of-motion under surgeon restrictions
Crutches or walker during protected weight bearing
Gradual abductor, quadriceps, and gait strengthening after healing permits
Hip precautions for at least 6 weeks if indicated by dislocation direction, surgical approach, or reconstruction

Avoid forcing hip motion early, especially flexion/adduction/internal rotation after posterior dislocation if posterior precautions are prescribed.

Important complications to explain to patients

Avascular necrosis (osteonecrosis) of the femoral head
Post-traumatic osteoarthritis
Heterotopic ossification
Sciatic nerve injury, foot drop, neuropathic pain
Hip instability or recurrent dislocation
Nonunion or malunion, particularly with associated femoral-neck fracture
Infection, fixation failure, DVT/PE after surgery
Need for later total hip replacement

A 2026 systematic review found adverse outcomes, including heterotopic ossification, osteoarthritis, and AVN, in roughly 35% overall across published series, emphasizing that follow-up is important even after a technically successful reduction or fixation. See the systematic review and meta-analysis.

Practical admission plan

For an admitted patient with suspected femoral head fracture-dislocation:

Admit under orthopedic trauma, with trauma or ICU care if polytrauma.
Keep NPO until CT and operative plan are finalized.
Document pre- and post-reduction neurovascular findings.
Obtain AP pelvis and lateral hip X-rays, then post-reduction CT.
Use multimodal analgesia and VTE prophylaxis unless contraindicated.
Maintain weight-bearing restrictions until CT and orthopedic review establish stability.
Schedule close follow-up: typically around 2 weeks for wound/X-ray review if operated, then 6 weeks, 3 months, 6 months, and 12 months or longer.

This is a general educational framework, not a substitute for the treating orthopedic surgeon’s plan. A femoral-head fracture with a dislocated hip, new numbness/weakness, cold foot, inability to reduce, or uncontrolled pain needs emergency management.
