Femur Fracture Physical Therapy Protocol
This protocol details rehabilitation post-femoral fracture, utilizing a multidisciplinary approach with surgeons and therapists.
Early mobilization, tailored exercises, and progressive weight-bearing are key components for optimal recovery and functional restoration.
Femur fractures represent significant orthopedic injuries requiring comprehensive rehabilitation to restore optimal function. This physical therapy protocol outlines a phased approach to recovery following a femur fracture, whether stabilized with intramedullary nailing or other fixation methods. The goal is to guide clinicians and patients through a structured program, maximizing strength, range of motion, and ultimately, a return to pre-injury activity levels.
Successful rehabilitation necessitates a collaborative effort between orthopedic surgeons, physical therapists, and the patient. Early mobilization, as highlighted in recent studies, is crucial. This protocol emphasizes progressive weight-bearing, proprioceptive training, and individualized exercise regimens. Consideration of specific fracture types – such as subtrochanteric or comminuted distal femur fractures – is also vital, as these may necessitate modifications to the standard progression. Post-implant removal rehabilitation also requires specific attention.
Understanding Femur Fractures
Femur fractures are breaks in the thigh bone, ranging in severity from stable hairline fractures to complex, comminuted breaks. These injuries commonly result from high-energy trauma, such as falls or motor vehicle accidents, but can also occur in individuals with weakened bones. Fracture location significantly impacts treatment and rehabilitation; proximal femur fractures (near the hip) differ greatly from distal femur fractures (near the knee), and subtrochanteric fractures present unique challenges.
Fixation methods, like intramedullary nailing, are frequently employed to stabilize the fracture. Understanding the specific fracture pattern and chosen fixation technique is crucial for tailoring the rehabilitation program. Comminuted fractures, involving multiple bone fragments, often require a more prolonged and cautious approach. Post-surgical considerations, including potential implant removal, also influence the rehabilitation timeline and goals, demanding a multidisciplinary approach.
Phase 1: Immediate Post-Operative (Weeks 0-4)
Initial focus is on pain and edema control, gentle range of motion, and weight-bearing as tolerated, progressing from assistive devices to independent ambulation.
Weight Bearing Protocol
Initial weight-bearing status is crucial and dictated by fracture stability and surgical fixation method. Typically, in the immediate post-operative phase (Weeks 0-4), patients begin with weight-bearing as tolerated (WBAT) utilizing assistive devices like walkers or crutches.
Progression occurs gradually, monitored by the physical therapist and surgeon. The goal is to transition from toe-touch weight-bearing to partial weight-bearing (PWB), then to weight-bearing as tolerated (WBAT), and ultimately to full weight-bearing (FWB).
This progression is dependent on radiographic evidence of healing and the patient’s pain levels. Intramedullary nailing often allows for earlier weight-bearing compared to other fixation methods. Careful assessment of gait and biomechanics is essential throughout the process, ensuring proper loading and minimizing stress on the fracture site. The timeline for achieving FWB varies significantly based on individual factors and fracture characteristics.
Range of Motion Exercises
Early initiation of range of motion (ROM) exercises is vital to prevent stiffness and maintain joint mobility following a femur fracture. In Phase 1 (Weeks 0-4), focus on active, active-assisted, and passive ROM exercises for the hip, knee, and ankle. Gentle ankle pumps and knee bends are initiated immediately to reduce swelling and improve circulation.
Hip ROM is progressed cautiously, avoiding excessive flexion or rotation that could compromise the fracture site. Emphasis is placed on achieving full knee extension. As pain subsides, the range of motion is gradually increased.
Proprioceptive training is incorporated to enhance joint awareness and neuromuscular control. These exercises help restore normal movement patterns and prepare the patient for more advanced rehabilitation. Consistent, gentle ROM exercises are crucial for optimizing functional outcomes and preventing long-term complications.
Pain Management Strategies
Effective pain management is paramount throughout the femur fracture rehabilitation process. Initially, pain control relies on prescribed analgesics, as directed by the orthopedic surgeon. Physical therapy interventions complement pharmacological approaches, focusing on reducing pain and improving function.
Modalities such as ice and elevation are employed to minimize swelling and alleviate discomfort. Gentle range of motion exercises, performed within a pain-free range, help to restore joint mobility and reduce muscle spasms.
Patient education regarding pain management techniques, including proper positioning and activity modification, is crucial. As rehabilitation progresses, the focus shifts towards active pain management strategies, such as strengthening exercises and proprioceptive training, to enhance functional capacity and reduce reliance on medication.
Edema Control
Post-operative edema is a common occurrence following femur fracture repair, significantly impacting comfort and hindering rehabilitation progress. Early and consistent edema control is therefore a critical component of the physical therapy protocol. Elevation of the affected limb above the heart is a foundational strategy, promoting venous return and reducing fluid accumulation.
Compression bandages are applied to minimize swelling and provide support. Gentle ankle pumps and active muscle contractions, performed regularly, aid in lymphatic drainage and circulation.
Monitoring the circumference of the leg provides objective data to track edema reduction. Patients are educated on self-management techniques, including proper bandaging and activity modification to prevent exacerbation of swelling. Consistent implementation of these strategies facilitates improved comfort, enhanced range of motion, and accelerated recovery.
Phase 2: Early Rehabilitation (Weeks 4-8)
This phase focuses on progressive weight-bearing, strengthening quadriceps, hamstrings, and glutes, alongside proprioceptive training to regain stability and function.
Progressive Weight Bearing
Weight-bearing progression is crucial during weeks 4-8, carefully monitored by the physical therapist. Initially, patients typically transition from non-weight-bearing to toe-touch weight-bearing, utilizing assistive devices like walkers or crutches. As pain subsides and radiographic evidence of healing progresses, partial weight-bearing is introduced, gradually increasing the percentage of body weight supported on the affected limb.
The goal is to achieve full weight-bearing by the end of this phase, but this is individualized based on fracture stability and patient tolerance. Regular assessment of pain levels, swelling, and gait pattern guides the progression. Emphasis is placed on proper form and avoiding compensatory movements. Transitioning from crutches to a cane, and ultimately to independent ambulation, is a key milestone. The protocol, as outlined by Gross (2026), emphasizes a tailored approach, adapting to individual needs and healing rates.
Strengthening Exercises ⎯ Quadriceps
Quadriceps strengthening is paramount in weeks 4-8, addressing significant muscle atrophy post-injury and immobilization. Initial exercises focus on isometric contractions – quad sets performed by tightening the thigh muscles without joint movement – to activate the muscle without stressing the fracture site.
Progressing to short-arc quads, performed with a small range of motion, builds strength and endurance. Straight leg raises, in various planes, further challenge the quadriceps. As weight-bearing increases, closed-chain exercises like wall slides and mini-squats are incorporated.
Resistance is gradually added using ankle weights or resistance bands. The aim is to restore full quadriceps strength, essential for gait normalization and functional activities. Consistent adherence to the prescribed exercise regimen, guided by a physical therapist, is vital for optimal outcomes.

Mirror feedback can be utilized to provide visual cues for correcting gait abnormalities. Emphasis is placed on increasing walking speed and endurance, gradually reducing assistive device reliance.
Proprioceptive exercises continue to play a role, enhancing awareness of limb position during gait. Regular assessment of gait parameters – step length, cadence, and joint angles – guides progression. The ultimate goal is independent ambulation with a normal gait pattern, minimizing compensatory movements and maximizing functional mobility.
Balance and Coordination Exercises
Restoring dynamic balance and coordination is crucial for functional independence following a femur fracture. Initial exercises involve static balance activities, such as single-leg stance with varying levels of support, progressing to dynamic challenges. These include tandem stance, reaching activities in multiple directions, and perturbation training to challenge reactive balance control.
Coordination drills, like walking with head turns or performing upper extremity movements while maintaining balance, are incorporated. Use of unstable surfaces – foam pads or wobble boards – further enhances proprioception and neuromuscular control.
Functional tasks, such as stepping over obstacles and navigating around furniture, are practiced to simulate real-life scenarios. The aim is to improve anticipatory and reactive postural adjustments, reducing the risk of falls and enhancing overall stability during ambulation and daily activities.
Phase 4: Advanced Rehabilitation & Return to Function (Weeks 12+)
This phase focuses on regaining full function, incorporating sport-specific training if applicable, and progressing to complex movements like squats and lunges.
Functional Exercises ⏤ Stair Climbing
Stair climbing is a crucial functional exercise progressively introduced to assess and improve lower extremity strength, balance, and coordination following a femur fracture. Initially, patients begin with assisted stair climbing, utilizing handrails for support and focusing on controlled ascents and descents. The therapist monitors for compensatory patterns, such as excessive trunk lean or hip hiking, providing cues to maintain proper biomechanics.
As strength improves, the level of assistance is gradually reduced, progressing to independent stair climbing with alternating reciprocal patterns. Emphasis is placed on full hip and knee extension during each step, ensuring adequate quadriceps and gluteal muscle activation. The height of the stairs can be modified to increase the challenge.
Progression includes negotiating varied stair surfaces and incorporating stair climbing into functional tasks, such as carrying light objects. The goal is to achieve independent, safe, and efficient stair climbing, replicating real-life demands and facilitating a return to prior functional levels.
Functional Exercises ⎯ Squats & Lunges
Squats and lunges are essential functional exercises designed to restore lower extremity strength, power, and functional movement patterns after a femur fracture. Initially, patients begin with partial-range squats, focusing on maintaining proper form – a neutral spine, engaged core, and controlled descent. Assistance may be provided using a chair or support for balance.
As strength improves, the range of motion is gradually increased, progressing towards full squats. Lunges are introduced, starting with short steps and emphasizing controlled knee tracking over the ankle.
