Acute post-surgical management of the amputee

Introduction

It is important to remember that the earlier the onset of rehabilitation, the greater the potential for success will be. The patient needs to receive physiotherapy treatment early to avoid complications such as joint contractures, pathological scars and depressed psychological state. The main post-surgical complications are cardio-vascular, residual limb pain and phantom sensation, oedema, contracture and wound dehiscence. [1]

Goals of acute post-surgical rehabilitation 

  • Obtain maximum independence
  • Prevent oedema
  • Maintain joint ROM
  • Prevent amyotrophy (muscle atrophy)
  • Increase the muscular activation
  • Prevent muscular weakness
  • Prevent bronchopneumonia
  • Prevent pressure sores
  • Control pain
  • Sensory reeducation
  • Support the client psychologically

It is intended that prior to any treatment, an assessment will be carried out by the physiotherapist. In this early stage, a functional assessment can be done including both upper-limb, lower-limb and trunk in order to evaluate the patient potential to carry out activities such as transfer, wheelchair mobility and ambulation (with or without prosthesis)[1]

Treatment modalities

Treatment modalities to prevent complications include:

  • Breathing exercises
  • AROM
  • Resistance exercises
  • PROM
  • Desensitising techniques
  • Stump management
    • Dressings
    • Prevention of oedema
    • Wound healing
    • Pain
  • Bed mobility and transfers
  • Positioning
  • ADL
  • Walking and wheelchair use

Breathing exercises

Deep breathing exercises and relaxation exercises will help to increase vital capacity, decrease anxiety and prevent bronchopneumonia

Active range of motion (AROM)

Amputated side (from the 1st post op day unless the post surgical dressing restricts motion):

  • First Hip flexion, ext, ADD, ABD 
  • Knee flexion exercises (for below-knee amputations (BKA)

Amputated side (from the 3rd post op day)

  • To reduce oedema BKA amputee should perform alternate knee flexion and extension.
  • The knee disarticulation and TF amputee should perform alternate hip flexion and extension, hip ADD and ABD.

These active exercises must be performed at regular intervals during the day (10 repetitions per hour).
Bilateral activities often achieve a more vigorous contraction on the amputated side.

Resistance exercises

From the 1st post op day

  • Isometric contraction of the quadriceps (BKA)
  • Isometric contraction of gluteus, ADD and hip internal rotation
  • Strengthening exercises of the sound lower limb (in progression)

From the 3rd post-op day

  • Resistance exercises of the upper limbs
  • Resistance exercises of the torso


PROM

Passive extension of a TT residual limb.[2]

The physiotherapist's hands should be positioned as proximal as possible to avoid any contact with the end of the stump, which is a very sensitive area. 

Massage, tapping, desensitisation, and scar mobilisation

Desensitisation is believed to reduce pain, help with tolerance and touch in the residual limb and may help the patient with an amputation adjust to his or her new body image that now includes limb loss. Massage and tapping can be started early on and could be done over the soft dressing or when it is off.[3] All these techniques could be done by the therapist and also taught to the patient/family member to do. Also instruct the patient how to perform desensitization and distraction techniques to reduce the phantom pain.

  • Massage[3]
    • Massage the entire residual limb with 1 or 2 hands by doing soft gentle kneading. Be cautious over the sutured area.
    • Once the sutures or clips are removed you can increase the pressure on the deeper muscles and soft tissue.
    • 5 Minutes 3-4 a day or as needed to to reduce phantom limb pain.
    • Gently massage the proximal residual limb, to include pressure points in the inguinal region
  • Tapping [3]
    • The residual limb should be tapped with fingertips (not the fingernails).
    • When the sutures or clips are still in then gentle tapping could be done over the suture line
    • This could also be done over the rigid or soft dressing
    • Once the sutures are removed a slapping motion could be done on the residual limb
  • Desensitisation[3]
    • This helps to make the residual limb less sensitive to touch and will improve the tolerance to touch.
    • 2-3 times a day when the soft dressing is off (this could be done during or after bathing)
    • Start by using a soft material, like a cotton ball, to gently rub the skin in circular motions.
    • Progress by using a rougher material, like a paper towel, and then progress to a towel or cloth until you can tolerate these materials.
  • Scar Mobilisation[3]
    • This will keep the scar from adhering to the underlying tissue as it could be the cause of pain and blisters when the patient start wearing a prosthesis.
    • Performed when the soft dressing or compression is off.
    • The patient can do this daily when taking a bath
    • Place two fingers over a bony portion and by keeping the fingers on the same spot make a circular motion for 1 minute.
    • Repeat this over and around bone on the residual limb
    • After wound healing, this could be done over the incision line to mobilise the scar tissue
[4]

Stump management

The ideal stump is one that is well-healed, has good vascular supply, soft and mobile scars, minimal pain, minimal oedema, a length sufficient for biomechanical leverage but not too long to restrict choices for prosthetic components, and large surface areas for distribution of pressure. While the surgery plays a large part in creating the ideal stump, Physiotherapy is required to maximise chances of achieving this ideal.

One of the main acute post-operative factors affecting the time to prosthetic fitting and the speed of rehabilitation, is the wound healing of the stump, especially in the vulnerable vascular compromised population[5]. Oedema in the residual limb is also a common complications after LLA surgery[6]. Controlling the amount of oedema post-surgically is vital for promoting wound-healing, pain control, protecting the incision during rehabilitation and assisting in shaping the stump for prosthetic fitting[7]. Traditionally soft dressings or non-adhesive elastic bandages are used to prevent oedema of the stump post-surgically, but no evidence supports the use of these bandages[8][9]. The use of immediate post-surgical rigid or semi-rigid dressings to prevent acute oedema have increased in popularity in the developed world, and is well supported by evidence in the literature[7][8].

Post-operative dressing

Post operative dressing are used to protect the limb, reduce swelling, promote limb maturation and prevent contractures. There are two major classifications of post operative dressing that are commonly used:

  • Soft dressings
    • Descriptive studies indicate several disadvantages of soft dressings, such as high local or proximal pressure, tendency to loosen or fall off, limited mobilization, and extended hospital stays.
    • Controlled studies found that the frequency of uncomplicated healing rates, postoperative pain, eventual use of a prosthesis, and mortality were not significantly different between soft and rigid types of dressings[10]
  • Rigid dressings - rigid dressings have been used as best practice for post-operative stump management for many years.
    • They come in 2 types:
      • non removable thigh length casts, which protect the stump and maintain the knee in extension; and
      • removable rigid dressings where the cast enclose the stump to just below the knee, thus allowing the amputee to have knee flexion, and are easily removable to allow inspection of the stump. (for evidence of use see[10])
    • Some of the reported benefits of the rigid dressing include promotion of wound healing, shaping of the stump, pain management, protection against trauma during falls, stump volume control and increased speed of prosthetic fitting[7][8].
    • The conventional method of application of rigid dressings is a plaster cast rigid dressing that is usually applied in theater under anaesthesia. This method has proven to be effective, but often surgeons choose not to opt for this method of rigid dressing since it is time-consuming, and requires some skill to apply[11]
  • Removable Ridged Dressing (semi-ridged dressing)
    • An alternative vacuum-formed removable rigid dressing has proven to be as effective as the conventional rigid dressing in a randomized controlled trial, and is an useful alternative to the plaster casting method[5].
    • The advantages of this vacuum-formed rigid dressing include the ease of application, and ease of access for wound inspection[5]. This dressing can be used for 5-7 days after surgery.

Oedema control (shrinking)

In the BACPAR guidelines for oedema management in lower limb amputees[12] they conclude that based on the best current available evidence rigid/semi rigid dressings should be used when expertise, time and resources allow; the benefits are well documented in the literature. The PPAM aid, compression socks and stump boards have been shown to have some evidence base for oedema control and may be used in addition or in the absence of rigid dressings dependent on clinical judgement. However, these modalities are not necessarily primarily intended for use for oedema control. Their advantages include preparation for prosthetic rehabilitation, reduction in flexion deformities and maintenance/improvement in muscle tone and are important components of amputee rehabilitation. Compression socks and the PPAM aid are the only tools available for transfemoral amputees. Although compression socks are widely used as a form of oedema control there is very limited evidence on aspects such as timing of application, who should assess appropriateness and the frequency it should be worn for. It is suggested that further research is required in order to offer more clarity for clinicians in these areas.[12]

Another option is the use of a post-op silicone liner:[13]

  • it is applied after the Removable Ridged Dressing is taken off
  • the same level of compression is applied to the residuum even if different people apply it
  • it decreases oedema and shapes the residuum for prosthetic fitting
  • helps with pain relief
  • fast track the rehabilitation process
  • It can be sterilized
  • the liner size is prescribed according to the circumference of the residuum and can be changed when the oedoma decreases
  • Disadvantages are: the cost involved, as the oedema goes down another size silicone liner needs to be applied, not readily available


Wound healing

Wound healing is always a cause of concern, but especially in the dysvascular population. Adequately controlling oedema of the stump can assist with healing, but some evidence also supports the use of low intensity laser in order to facilitate and speed up wound healing in diabetic patients [5]. However the exact dosages for optimal effect has not yet been established.

Pain

Pain is a very common physiological stressor that occurs during the acute postoperative period and affects the patient’s ability to learn new skills [7] . Adequately controlling the new amputee’s levels of pain greatly facilitates their early rehabilitation [7] . Physiotherapists should take this into consideration, and treat patients shortly after receiving their pain medication. Controlling oedema in the residual limb through positioning also assists in relieving acute postoperative pain [7]. Various physiotherapy interventions are used for the management of phantom limb pain, but very few of these have been studied to prove their efficacy in the research literature [14]. One of the few physiotherapy modalities that has been proven to be effective for the management of phantom limb pain, is a 60 minute application of Transcutaneous Electrical Nerve Stimulation (TENS) [6].

Patient information

A series of useful patient information guides from the Amputee Coalition.

Bed Mobility [15]

  • Bridging
  • Rolling from one side to the other
  • Sitting forward bilateral amputation
  • Moving up and down on the bed.
  • Push-ups using arms (after drain has been removed).

Transfers

  • Standing pivot transfer (for a patient that can participate only partially) 
  • Backwards forwards transfer (for patient with a bilateral amputation)
  • Transfer3.png
  • Lateral transfer with a sliding board transfer 
[16]


Positioning

The main goal of a good positioning at any time is to prevent adjacent joint contractures.

  •  For trans-tibial amputee complete knee extension and flexion is needed and
  • For the trans-femoral amputee and knee disarticulation amputee - the full ROM of the hip, especially extension and adduction.

Full ROM will ease prosthetic fitting and ambulation[1]

Patient should be advised on how to position themselves while sitting and lying in the hospital bed or standing to prevent contractures. 

  • For trans tibial :  avoid as much as possible long position with a knee flexion (cushion under the knee for example)
  • For trans femoral : avoid position with hip flexion and abduction (cushion under the stump for example).
