ABSTRACTS OF PAPERS PRESENTED AT THE 93RD RESEARCH MEETING OF THE MEDICAL RESEARCH CENTRE OF BOMBAY HOSPITAL ON MONDAY, 14TH JANUARY 2002, 2.30 PM SP JAIN CAFETERIA (CONVENOR DR. HL DHAR)

1. EPIDUROSCOPY : AN INTERVENTIONAL PAIN MANAGEMENT FOR POST LAMINECTOMY PAIN - A FIRST CASE REPORT - FROM INDIA

DK Baheti, A Deshpande, V Patil
This report describes the first epiduroscopy done in India, to perform adhesinolysis for relief of backache and radiculopathy in a patient of post laminectomy pain. There was adequate pain relief and definite improvement in functional capacity after the procedure. Post laminectomy pain or failed back syndrome with its resultant chronic low back pain is estimated to occur in 20% to 50% of the patients. Soft tissue pathology is not easily examined so it is often overlooked as a potential cause of some types of back pain syndrome.


2. PHYSIOTHERAPY MANAGEMENT FOR VERTIGO

Albert K Mendonca, RB Patel

We have taken into account 20 patients who have complained of vertigo and of different diagnosis.

Out of these 20 patients 10 were diagnosed as cervical spondylosis and seven as middle ear infection and 3 as cerebral infarction.

These 10 patients with cervical spondylosis got good benefit after the Cawthorne-Cooksey exercises, neck muscles strengthening exercises and atlanto-axial mobilization. In about 3-4 weeks times they got fully recovered and the seven patients with the middle ear disease got recovered only through Cawthorne-Cooksey exercises. They too got total recovery in about 6-10 weeks time. And the patients with cerebral infarction the recovery was a bit slow and it took about
8-15 weeks to get complete recovery.


3. BLOOD MANAGEMENT IN TOTAL KNEE ARTHROPLASTY

Narayana Prasad, Vinod Padmanabhan, Arun Mullaji

A prospective study was done at Bombay Hospital for 6 months, to reach a conclusion regarding the blood loss and blood transfusion incidence in Primary Total knee arthroplasty (TKA).

It was found that gender has a role in total blood loss during TKA. The diagnosis of the disease (OA/RA) does not have any role in total blood loss. The indication for transfusion was mainly low pre-operative haemoglobin value rather than intra-op blood loss.


4. PHYSIOTHERAPY IN KNEE ARTHROPLASTY

Shilpa Mitgaonkar, Asha Andyal

It is defined as replacement or reconstruction of a joint using an artificial prosthesis.

Their types being - Total, Partial and Excision.

AIMS for doing Arthroplasty of knee joint are-

1. To relieve pain.

2. To improve mobility as well as provide stability.

3. To correct any deformity if present.

Pre-requisites for Knee Arthroplasty

a) Biological compatibility.

b) High resistance to wear and tear.

Combination of plastic with metal is used to decrease coefficient of friction, high resistance to corrosion, therefore implant will have a longer time i.e. durability is longer.

Pre-requisites are pertaining to the biomechanics of knee joint. Implant that one uses must give (1) near (M) range of movement in all the planes. (2) Prosthesis used should mirror the mechanics of the original joint only then it will be stable i.e. femoral condyles glide and slide on the tibial condyles at the same time they rotate.


5. ACCURACY OF INTRAMEDULLARY ALIGNMENT SYSTEM IN TOTAL KNEE ARTHROPLASTY

Vinod Padmanabhan, Arun Mullaji

The angle formed between the femoral anatomic axis and the femoral prosthesis was measured on radiographs of 206 consecutive total knee arthroplasties to evaluate the efficacy of intramedullary guide rods for achieving coronal alignment and to identify the factors that predispose to unacceptable distal femoral cuts. In this prospective study, the radiographs of knee with distal femur were taken on 14 inches x 17 inches cassette and only those with good centring without rotations were included. Intramedullary femoral alignment system was used in all cases.

The mean femoral component angle relative to femoral anatomic axis was 4.9o valgus with a standard deviation of 1.5o and a range of 1o to 9o valgus. 186 (90.3%) knees had a femoral component angle of 3o-7o valgus, which is considered to be ideal 20 (9.7%) knees had a femoral component angle that was â 2o valgus or ô 8o valgus which is considered to be less than ideal. 3 case had distal femoral bowing that caused an excessive valgus cut. 5 cases had wide femoral canals that caused inaccurate cuts due to eccentric placement of intramedullary guide rod.

Pre-operative full-length hip-to-ankle radiographs should be done to identify significant anatomic variations, in which errors are more likely. We conclude that intramedullary alignment system for the distal femoral cut is an excellent method for most cases.


6. QUADRICEPS TENDON RUPTURE AFTER TOTAL KNEE ARTHROPLASTY - A CASE REPORT

Vinod Padmanabhan, Narayana Prasad, Arun Mullaji

A 74 year old female who had undergone left total knee arthroplasty (TKA) 6 months ago elsewhere, presented with difficulty in walking and inability to extend her knee since then. She had been walking with a knee brace without pain for the past 6 months. On examination, there was a dimple in the suprapatellar region; range of movement 0-90 and no active extension was possible. Knee score was 73 and Function score was 5. X-rays showed loosening of femoral and tibial component, osteolysis and patella baja (low lying patella).

Patient was taken up for revision surgery. Discontinuity in the quadriceps tendon was found just above the patella and it had retracted proximally by about 4 cm. Femoral and tibial components were revised with TC3 implant system along with contained bone grafting while patella was not revised. Repair of the quadriceps tendon was done by Codivilla's procedure in which an inverted 'V' flap was mobilized from the muculotendinous junction and end-to-end repair done. Post-operatively, lower limb was immobilized in a POP slab with knee in 20 degrees flexion. Gentle knee flexion was started on 2nd post-operative day (POD) along with static quadriceps exercises and electrical stimulation. Full weight bearing walking with rigid knee brace was started on 7th POD and active knee extension on 14th POD. Patient had an extension lag of 15 degrees at 3 weeks post-operatively when she was discharged. At 3 months follow-up, patient had full extension actively, no instability and range of movement 0-90.


7. MANAGEMENT OF LYMPHOEDEMA

R Deshpande, R Ginwalla, K Khadalia, V Tambwekar, SR Tambwekar

Lymphoedema develops as a result of an imbalance between the lymphatic transport capacity and the lymphatic load. Primary lymphoedema due to lymphatic malformations may manifest at birth or even after 35 years of age. Secondary lymphoedema can be caused by filariasis, tuberculosis, circumferential limb trauma, circular amniotic bands, malignancies, following - radiation, block dissection of lymph nodes, venous stripping, lipectomy, peripheral vascular surgery or following lymphangiosis caused by bacteria, fungi, insects or geochemical irritants and it may even be brought about by self-mutilation.

Various surgical procedures have been described to reduce the lymphatic load, increase lymphatic transport capacity or to improve the drainage.

Based on the MRI Venography findings Venolysis of the femoral vein was performed in eight cases over the last ten years. There was a significant reduction in the oedema during the fortnight following surgery. The results were maintained by continued implementation of the conservative measures.
