Post-Amputation Care and Rehabilitation

The proper management of the residual limb (stump) following amputation is a critical component of post-operative care. Meticulous bandaging, combined with the appropriate use of prosthetics and orthotics, supports healing, controls swelling, and prepares the limb for functional independence.

Foundational Role of Stump Bandaging

Stump bandaging is not merely a wound care measure; it plays a foundational role in prosthetic success. It helps control edema, shape the stump, and prevent complications, ultimately preparing the limb for prosthetic fitting.

Objectives of Stump Bandaging

  • Edema Control: Prevents fluid buildup that may delay healing and affect prosthetic fitting.
  • Shaping the Stump: Achieves a conical shape ideal for prosthetic attachment.
  • Desensitization: Helps reduce hypersensitivity in the residual limb.
  • Protection: Guards the stump from external trauma and infections.
  • Pain Reduction: Compression helps alleviate post-operative pain and phantom limb sensation.

General Bandaging Principles

Regardless of the amputation level, several key principles must be followed:

  • Use elastic or crepe bandages (size varies by limb).
  • Wrap in a figure-of-eight pattern to ensure even pressure.
  • Apply more pressure distally (towards the end of the stump) and gradually decrease pressure proximally (towards the body).
  • Avoid circular turns, as they can cause a tourniquet effect and impede blood flow.
  • Secure the bandage with tape or Velcro, never metal clips or pins.
  • Re-wrap the stump every 4–6 hours, or several times daily, as swelling changes.
  • Monitor the skin regularly for signs of irritation, redness, or breakdown.

Lower Limb Stump Bandaging Techniques

Above-Knee (AK) Stump Bandaging

Above-knee amputations require diligent care to shape the thigh stump for a prosthetic limb. Bandaging helps reduce swelling and provides the necessary compression to mold the limb appropriately.

Procedure:

  1. Use wide elastic or crepe bandages, typically 6 to 8 inches.
  2. The patient should lie flat or slightly elevate the stump.
  3. Begin with an anchor around the waist or pelvis to prevent slipping.
  4. Bring the bandage down diagonally to the stump, wrapping in a figure-of-eight pattern around the thigh, and then back to the pelvis.
  5. Repeat in overlapping layers, ensuring firm but not overly tight compression.
  6. Encourage the patient to lie prone periodically to prevent hip flexion contractures.

Below-Knee (BK) Stump Bandaging

Proper bandaging of a below-knee stump is essential for achieving the conical form necessary for comfortable prosthetic application.

Technique and Key Points:

  • Use an elastic bandage, commonly 4 or 6 inches wide.
  • Bandaging should begin at the end of the stump and proceed in a figure-of-eight pattern upward toward the knee.
  • Ensure even tension throughout the wrap.
  • The bandage must cover the end of the stump securely without creating wrinkles or excessive pressure points.
  • Avoid cutting off circulation or causing pressure sores.

Upper Limb Stump Bandaging Techniques

Hand and Elbow Stump Bandaging

For individuals with partial hand, complete hand, or elbow amputations, the primary goals are to reduce edema, protect healing tissues, and maintain functionality of the remaining limb.

Hand Stump Bandaging:

  • Use a 3 to 4-inch elastic bandage.
  • Start at the palm or end of the stump, wrapping with a spiral or figure-of-eight pattern around the stump and wrist.
  • It is essential to include part of the forearm to prevent swelling above the bandaged area.

Elbow Stump Bandaging:

  • Use a 4–6 inch elastic bandage.
  • Begin from the upper arm, anchoring the bandage.
  • Proceed in a figure-of-eight motion around the stump and elbow area.
  • Key Consideration: Avoid restricting shoulder or axillary movement.

Proper bandaging helps the stump maintain a conical shape, which is vital for prosthetic fitting.

Prosthetics and Orthotics

The success of rehabilitation depends heavily on the condition of the stump. Poorly shaped stumps or unmanaged edema can lead to pressure sores, pain, and reduced prosthetic wear time.

Prosthetics: Replacing Missing Limbs

Prosthetics are artificial devices designed to replace a missing limb, restoring functional independence and quality of life.

Lower Limb Prosthetics (AK/BK)

For AK and BK amputees, prostheses typically include a socket (which holds the stump), a knee mechanism (for AK), a pylon (shaft), and a foot. These devices must be custom-fitted.

Types of Ankle/Foot Components:

  • Solid Ankle Cushioned Heel (SACH) Foot: A basic prosthetic foot with no moving parts, often used for low-activity individuals.
  • Dynamic Response Feet: Designed with flexible materials like carbon fiber; they store and return energy during walking, suitable for active users.
  • Articulated Foot Prostheses: Include mechanical joints that allow ankle movement, improving adaptability on uneven terrain.

Upper Limb Prosthetics (Hand/Wrist)

Upper limb prosthetics restore function and appearance and vary widely based on the level of amputation and user needs.

Types:

  • Passive Prosthetics: Primarily cosmetic and lightweight, offering minimal function.
  • Body-Powered Prosthetics: Operated using cables and harnesses, usually with a hook or mechanical hand, allowing grasp and release functions.
  • Myoelectric Prosthetics: Controlled by electrical signals from the muscles in the residual limb, offering better grip and wrist rotation.

Orthotics: Support and Alignment

Orthotics are external devices designed to support, align, or improve the function of the musculoskeletal system. They may be used in conjunction with prosthetics or independently to address existing conditions.

Lower Limb Orthotic Interventions

Orthotics are used when the limb is intact but weakened or misaligned (e.g., due to stroke or foot drop). They may also be necessary for AK amputees if there are associated complications like hip instability.

Common Types:

  • Ankle-Foot Orthosis (AFO): A brace that supports the ankle and foot, preventing plantarflexion and supporting dorsiflexion.
  • Dynamic AFOs: Allow controlled movement while providing support.
  • Hip Orthoses: Used to stabilize joints or address weakness in the hip area.

Upper Limb Orthotic Interventions (Wrist)

Wrist orthoses are supportive devices designed to immobilize, protect, or assist movement of the wrist joint, commonly used in cases of sprains, fractures, nerve injuries, or carpal tunnel syndrome.

Types:

  • Static Wrist Orthosis: Immobilizes the joint to allow healing.
  • Dynamic Wrist Orthosis: Provides support while allowing controlled movement.
  • Functional Orthosis: Assists movement or compensates for muscle weakness.

Gait Training and Functional Analysis

Gait training and analysis are essential components in the rehabilitation of patients fitted with orthoses and prostheses, ensuring they regain efficient, safe, and functional mobility.

Gait Training for Device Users

Gait training is the therapeutic process aimed at teaching or retraining individuals to walk effectively using their assistive devices. This training is highly individualized.

Goals of Gait Training

  • Improve balance and coordination.
  • Enhance weight-bearing on the affected or residual limb.
  • Develop a smooth, energy-efficient walking pattern.
  • Prevent compensatory movements that may cause secondary injuries.
  • Increase endurance and confidence in ambulation.

Process of Gait Training

  1. Initial Assessment: Therapists evaluate muscle strength, joint range of motion, stump condition, and cardiovascular fitness to tailor the program.
  2. Weight Bearing Exercises: Patients gradually bear weight on their device to build tolerance and prevent discomfort.
  3. Balance and Posture: Focus on improving trunk stability and posture using standing exercises and balance boards.
  4. Step Initiation and Progression: Training starts with static balance, progressing to walking with assistive devices like parallel bars or walkers.
  5. Practice on Various Surfaces: Patients practice walking on different surfaces (carpets, stairs, ramps) to simulate real-life conditions.
  6. Energy Efficiency: Emphasis is placed on minimizing excessive movements and compensations that increase energy expenditure.

Systematic Gait Analysis

Gait analysis is a systematic study of human walking used to identify abnormalities, inefficiencies, and compensations in gait patterns. It guides adjustments to devices and rehabilitation programs.

Methods of Gait Analysis

  • Observational Gait Analysis: Clinicians visually assess the patient’s walking pattern to note deviations (e.g., limping, hip hiking).
  • Video Analysis: Slow-motion recording allows detailed study of joint angles and timing.
  • Instrumented Gait Analysis: Advanced systems use force plates, motion capture cameras, and electromyography (EMG) to measure ground reaction forces and muscle activity.

Parameters Evaluated

  • Step length and cadence.
  • Symmetry between limbs.
  • Joint range of motion during stance and swing phases.
  • Prosthetic or orthotic alignment effectiveness.
  • Energy expenditure during walking.

Conclusion: Holistic Amputation Recovery

Effective rehabilitation following limb loss or injury involves a multidisciplinary approach. Stump bandaging is a foundational step, essential for edema control and shaping the residual limb for prosthetic use. Prosthetics restore functional independence, while orthotics offer vital support and protection for compromised structures.

The integration of comprehensive gait training and detailed gait analysis ensures that prosthetic and orthotic users achieve optimal functional outcomes, minimize complications, and regain confidence in their mobility, ultimately enhancing their overall quality of life.
