A fall that seems minor can cause a serious hip fracture in an older adult, particularly when osteoporosis or reduced bone strength is present. Hip fractures require timely medical evaluation because they can significantly affect mobility, independence, and overall health.
For certain fractures involving the neck of the femur, bipolar hemiarthroplasty treatment may be considered. It is a type of partial hip replacement in which the damaged femoral head is replaced while the patient's natural hip socket is retained.
Understanding why this procedure is recommended for some fractures helps families participate more confidently in treatment discussions.
Why are femoral neck fractures different?
The femoral neck is the narrow region connecting the ball of the hip joint to the upper femur. Certain displaced fractures in this area can disrupt the blood supply to the femoral head.
In an older patient, simply fixing a severely displaced fracture with screws may not always provide the most suitable outcome because healing potential, bone quality, fracture pattern, and blood supply all matter.
An orthopaedic surgeon therefore evaluates several factors before choosing between internal fixation, hemiarthroplasty, or total hip replacement.
What is bipolar hemiarthroplasty?
In hemiarthroplasty, the damaged femoral head is replaced with a prosthetic component. A bipolar implant has an additional articulation within the prosthetic head.
Unlike total hip replacement, the natural acetabulum or hip socket is not routinely replaced.
This distinction matters because different operations are appropriate for different patients.
Who may be considered for this treatment?
Bipolar hemiarthroplasty may be considered for selected older adults with displaced femoral neck fractures. The final decision depends on factors such as:
- Fracture type and displacement
- Patient age
- Bone quality
- Mobility before the fracture
- Cognitive and functional status
- Existing hip arthritis
- Other medical conditions
- Ability to participate in rehabilitation
A highly active older adult with pre-existing hip arthritis, for example, may have different surgical considerations from a frail patient with limited mobility before the fracture.
Why is rehabilitation important?
Surgery addresses the fractured joint, but recovery involves much more than the operation.
Prolonged immobility in elderly patients can contribute to muscle weakness, loss of independence, pressure-related problems, and other medical complications. Rehabilitation therefore aims to restore safe mobility as appropriate to the patient's overall condition.
Physiotherapists may work on bed mobility, standing, walking with support, strengthening, balance, and progression of daily activities.
Families also play an important role after discharge by helping create a safer home environment. Loose rugs, inadequate lighting, slippery bathroom floors, and unsuitable footwear can increase the risk of another fall.
Questions families should ask
When an elderly family member sustains a hip fracture, ask why a particular operation has been recommended and what alternatives were considered.
It is also useful to understand expected mobility after surgery, rehabilitation requirements, weight-bearing instructions, wound care, medication, and follow-up arrangements.
For families in Bengaluru and other parts of Karnataka, proximity to appropriate orthopaedic care and rehabilitation support can be particularly important when an elderly patient needs continuing assistance after a hip fracture.
At Dr Harish Madrekar's Orthopaedic Clinic in Bengaluru, hip conditions can be assessed in the context of the patient's fracture pattern, mobility needs, general health, and recovery requirements.
Bipolar hemiarthroplasty is not automatically the correct operation for every hip fracture. Careful patient selection remains central to deciding whether partial replacement, total replacement, fixation, or another approach is most suitable.
