A Case of Below Knee Amputation for Prosthetic Rehabilitation: Amputee Case Study
A Case of Below Knee Amputation for Prosthetic Rehabilitation
This piece of case presentation describes the prosthetic rehabilitation of a diabetic below knee amputee. It entails client's characteristics, medical diagnosis, examinations and findings using the ICF findings adopted by World Health Organization which gives a globally accepted framework and system of classification.
At the end of my prosthetic rehabilitation, client was able to achieve her goals of regaining confidence, mobility and independence resulting to reintegration into the society and to work
Amputation, Transtibial, Diabetic, Phantom Limb Pain, Sensation, Range of Motion, Muscle Strength
Client is a 55 years old married woman, residing in a rural area in Mbaise Local Government Area in Imo State, Nigeria with her family (husband & children) in a bungalow building. She is a teacher by profession. Client presents with a Below Knee Amputation secondary to Diabetic Foot Ulcer
She is known for Diabetes mellitus (Dm) and it is hereditary in her family.
Client is also hypertensive and experiences diabetes retinopathy.
She visits an endocrinologist for control of Diabetes control, an ophthalmologist for treatment of diabetes retinopathy and also she is on antihypertensive to control her high blood pressure
Amputation is secondary to Diabetic Foot Ulcer (DFU) and amputation surgery was at the transtibial level of the right lower leg (RLL) carried out in August, 2014. Client has a stump length (knee centre to distal end of stump) of 15cm. She complains of Phantom Limb Pain, a sharp feeling usually experienced at cold weather for 3months after amputation surgery.
Client goal is to regain mobility with a prosthetic limb, increase independence and confidence.
Her amputation is on the right lower limb at the transtibial level. Range of motion at the knee joint is normal (flexion&extension 1100), good skin integrity, good muscle strength (flexors +4, extensors +3); stump is distally heavily padded, sound contra-lateral limb and good upper limb function for donning and doffing of prosthesis. Client has no other impairment except for the amputation on the right lower limb.
Client was a teacher before amputation surgery. After which, she can no longer carry out her teaching profession effectively because of the disability. She is independent for some activities such as cooking, washing, dressing etc. She cannot walk long distance with her crutches due to increase in energy consumption and she is willing and motivated to use prosthesis Her environment is a rural environment and the major form of transportation is with the use of cycle. This limits her mobility as she cannot ride with the disability but she has a good support from her family.She scored 18/30 in AMPnoPRO
Based on my evaluation, client ultimate goal is to regain mobility and confidence. From my assessment using Amputee Mobility Predictor Assessment Tool (AmpPro/AmpnoPro), I, therefore, deduce an clinical hypothesis alternate that Client can be rehabilitated successfully using a prosthesis.
Client was referred to me by an orthopedic surgeon for prosthetic rehabilitation.
As a Prosthetist, she was cancelled and advised on the type of prosthesis that will be suitable for her. She was assessed; measurement of the stump and contra-lateral limb was taken (length of foot inclusive), followed by casting to get an impression of the stump. A positive mould was made from the cast and was modified to suit client measurement with due consideration to the pressure sensitive and tolerant areas.
Using Resin Technology, the socket (PTBSc) was produced and coupled with other prosthetic component (Aluminium pylon and SACH Foot).
Client was invited for initial prosthetic fitting and gait training. During this stage, her complain were noted such as length discrepancies (between normal and prosthetic limb), gait deviations (valgus moment) were observed, recorded and corrected. Alignment was made as necessary to give client good comfort and confidence.
Gait training was done intensively thrice in a week for 2weeks due to the high cost of transport. Client was able to ambulate on prosthesis and gait was done with a walking frame at the first week of training and then with a quad cane at the second week. She showed good confidence during gait training.
After the stage of successful gait training, the prosthetic limb was given a good cosmetic appearance based on the client taste and need and finally fitted on patient.
she ambulates on prosthesis with a cane and follow up was done
After the prosthetic rehabilitation, my client was able to achieve her goal of regaining mobility, independence and confidence. She meets up with her check up and follow up management and explains her experiences returning to work effectively.Client was reintegrated into her community/society.
In summary, the case presented above is on prosthetic rehabilitation of a diabetic amputee. At the first three months of amputation surgery, client experiences Phantom Limb pain and sensation. This as summarized by Katz (2009) in the Therapy for Amputees textbook, can occur as a result of complex interaction of inputs from periphery and wide spread region of the brain sub-serving sensory, cognitive and emotional processes.
Also, the International Classification of Functioning, Disability and health (ICF)  by World Health Assembly was very helpful to describe, assess and compare function and disability of client.
Also, the outcome measure tool- The Amputee’s Mobility Predictor (AmpPro/AmpNoPro) was gainful in knowing what the client can do before and after prosthetic rehabilitation. Though it is my first case of using such tool but am glad I was able to use it for an outcome measure on the client.
Though in Nigeria, an interdisciplinary approach is not effectively practice but with the impact of knowledge I have gained in this course, I hope to get more involved with other health team practitioners especially the physiotherapists so as to successfully rehabilitate an amputee holistically.
