Hip Orif Physical Therapy Protocol

Getting Through Hip Orif Physical Therapy Protocol Without Losing Your Mind

I've worked with hip fracture patients for about twelve years now. The surgeries vary—cannulated screws for femoral neck fractures, sliding hip screws for basic intertrochanteric fractures, and intramedullary nails for reverse obliquity patterns. Each one has different weight-bearing restrictions and different timelines. Most protocols you'll find online are too generic. They don't account for the fact that a 78-year-old with osteoporosis moves differently than a 55-year-old with a high-energy fracture. The standard approach starts with isometric quadriceps sets on day one. You can do those regardless of surgical fixation. Then add gluteal squeezes. The patient lies supine and tightens the buttocks for five seconds, relaxes for five. Repeat ten times, three sets daily. It sounds trivial but most people skip it because they're focused on pain management. Those gluteal contractions matter more than you'd think for preventing the falls that wreck your progress later.

Hip Orif Physical Therapy Protocol Basics

Weight-bearing status depends entirely on the surgeon and the fracture pattern. Per the AAOS guidelines, most intertrochanteric fractures treated with a sliding hip screw or cephalomedullary nail get weight-bearing as tolerated immediately. That doesn't mean walking around the hospital like nothing happened. It means you can put as much weight as pain allows through the surgical leg while using a walker or partial weight-bearing if balance is questionable. Femoral neck fractures fixated with cannulated screws often carry protected weight-bearing restrictions for six to twelve weeks. The biology here is unforgiving. Blood supply to the femoral head is already compromised in many of these fractures. Pushing too hard too early risks avascular necrosis or hardware failure. I had a case last year where a patient ignored the partial weight-bearing orders, progressed to full weight-bearing at week three, and ended up with a collapsed femoral head requiring total hip arthroplasty at week six. She'd been walking fine initially, which made it worse—she assumed she was healing properly. Range of motion protocols vary by surgical approach. Anterior approach fractures typically allow full hip flexion, abduction, and external rotation earlier than posterior approach cases. Posterior approach requires hip flexion precautions under 90 degrees for six to eight weeks minimum. The rule is straightforward but patients don't follow it well because it conflicts with daily activities like sitting on low chairs or tying shoes.

What Actually Works in Practice

Axillary crutches or a front-wheeled walker serve most patients through the first four to six weeks. Standard four-point walkers are fine for patients with good upper extremity strength and balance. I prefer front-wheeled walkers for elderly patients because they're easier to maneuver on carpeted floors and don't require lifting the entire device with each step. Patients who get a standard square walker often abandon it within two weeks because it's frustrating to use. Stationary cycling starts around week six for patients with adequate hip flexion range. Begin with no resistance, seat height adjusted so there's slight knee bend at the bottom of the pedal stroke. Fifty revolutions forward, fifty backward, two sets. This maintains hip flexion range without placing significant load through the femoral neck or trochanteric region. If the patient reports groin pain during cycling, back off. Pain here usually means the fixation isn't stable enough or there's early hardware irritation. Resistance band work begins around week four to six depending on healing progress. Start with hip abduction bands—patient lies on the non-operative side, band around the operative thigh just above the knee, lift the leg against resistance. Three sets of ten repetitions. Progress to hip extension bands with the patient prone. These two movements address the most common deficits I see after hip ORIF: weak abductors causing Trendelenburg gait, and weak extensors causing anterior pelvic tilt during gait.

Balance training is where most protocols fail. Patients focus on strengthening but neglect proprioception. Single-leg stance on the non-operative leg, ten seconds, three reps. Progress to eyes closed when tolerated. Then advance to single-leg stance on the operative leg once weight-bearing is progressed. Add a foam surface under the standing leg for difficulty. This prevents the recurrent falls that lead to periprosthetic fractures or implant failure.

Common Pitfalls I See Regularly

Patients rush into stair climbing before they have adequate single-leg strength. The rule of thumb is that stairs require roughly 1.5 times body weight through the operative leg. If a patient can't perform a single-leg squat to 30 degrees without hip hiking or trunk leaning, they're not ready for stairs without a rail. I've seen too many patients fall on stairs at week three because their therapist cleared them prematurely. Another issue is ignoring the non-operative side. Patients focus entirely on the surgical leg and neglect the contralateral lower extremity. This creates strength asymmetry that persists for months. Test both sides at baseline and at each follow-up. The non-operative leg should match within 10% of the surgical leg by week twelve. If it doesn't, the patient will have compensatory gait patterns that cause lower back pain and eventually degrade the hip joint on the surgical side. Pain management affects everything. Opioids impair balance and increase fall risk. NSAIDs may impair bone healing in the early phases. Acetaminophen combined with cold therapy and elevation manages most post-operative pain adequately without these side effects. I recommend acetaminophen 1000mg every six hours around the clock for the first week, then taper as needed. Most patients can transition to PRN use by day ten to fourteen.

When Things Don't Go as Planned

Not every hip fracture heals predictably. Diabetes, smoking, and poor nutrition significantly increase nonunion risk. I had a patient who smoked two packs daily and ignored dietary counseling. Her intertrochanteric fracture showed no callus formation at twelve weeks despite appropriate fixation. She required a revision procedure with bone grafting at sixteen weeks. The original protocol wouldn't have predicted this—you need to monitor radiographic healing at six-week intervals and adjust expectations accordingly. Hardware irritation is another common complication. Patients with low BMI often feel the screw heads or plate through thin subcutaneous tissue. This isn't dangerous but it's uncomfortable and can limit range of motion progression. In these cases, I recommend activity modification rather than pushing through pain. The hardware can be removed electively after fracture union is confirmed, usually around twelve to eighteen months post-operatively. Severely osteoporotic patients may need adjunctive therapy beyond standard physical rehabilitation. Denosumab or teriparatide can improve bone mineral density and reduce re-fracture risk. This isn't part of the physical therapy protocol itself but it's relevant to overall outcomes. Coordinate with the orthopedic surgeon regarding pharmacological bone health management.

Progression Milestones

Week one: independent transfers with assistive device, ambulation 50 to 100 feet with supervision, completion of home exercise program with minimal cues. Week four: single-leg stance on non-operative leg for 20 seconds, stationary cycling with minimal resistance, stair climbing with rail and step-to pattern. Week six: single-leg stance on operative leg for 10 seconds, progression to cane if gait is symmetric, unassisted stair climbing with rail. Week twelve: normal gait pattern without assistive device for most patients, return to community ambulation, resumption of pre-injury recreational activities as tolerated. Most patients achieve functional independence by week twelve. Those who haven't progressed to cane use by week eight typically require extended therapy or home health services. Document functional milestones objectively—gait speed, step count, transfer independence—rather than relying on subjective pain scores alone. A patient reporting zero pain but walking at 0.4 meters per second needs different intervention than one reporting moderate pain but walking at 0.8 meters per second. The biggest variable is the patient's baseline function before surgery. A community ambulator who lived independently prior to fracture recovers faster than a non-ambulator or someone who required assistance for activities of daily living before the injury. Pre-hospitalization functional status predicts post-discharge outcomes better than age or fracture type alone. Screen for this early and set realistic expectations with patients and families.

Discharge planning matters. Home health physical therapy provides three visits per week for six to eight weeks, which is often insufficient for complex cases. Outpatient therapy starting two to three weeks post-discharge allows progression beyond basic activities. I recommend transitioning to outpatient therapy when the patient can safely navigate their home environment and has demonstrated consistent participation in the home exercise program for at least one week. Return to driving typically occurs around week six to eight for right-sided procedures, provided the patient can perform an emergency stop without hesitation. Left-sided procedures don't require the same restriction unless the patient has automatic transmission complications. Verify with local regulations and the surgeon's preference regarding driving clearance. Occupational therapy involvement is often overlooked but important for home safety modifications. Grab bars in bathrooms, raised toilet seats, shower chairs, and removal of throw rugs prevent secondary injuries. Address these at discharge planning rather than waiting for the patient to discover they need them after returning home.
