The to check rotation and to correct the

The disorders pertaining to the hip joint include a variety
of pathologies like congenital , traumatic, infective and degenerative.
Considering these facts, it is not surprising that an extraordinarily large
number of procedures have been described in literature for the reconstruction
of hip. Orthopaedic surgeons continue to discuss which surgical
approach is best for primary THA because both of these approaches have merits
and limitations. A Cochrane review by Jolles and Bogoch14 concluded,
despite numerous studies examining the effect of surgical approach in THA, the
quality and quantity of such trials were insufficient to enable a firm
conclusion regarding whether one approach was superior to the other. A number of
technical intricacies allow safe and efficient femoral and acetabular
reconstruction when using each approach. Hip dislocation, abductor
insufficiency, fracture and nerve injury are complications of hip joint
arthroplasty, although their relative risk varies by approach. Numerous
clinical trials have sought to elicit differences in patient-reported outcomes,
complication rates and return to function among the surgical approaches.
Hence
we need the surgical approach which provides the best clinical outcome for the
early rehabilitation and recovery of the patient.

The study was carried out in the department of Orthopaedics,
S.N. Medical college, Agra from January 2016 to March 2017. The cases were
selected among the patients attending emergency as well as outdoor clinics of
dept. of Orthopaedics. All cases of traumatic and degenerative hip pathologies
admitted in S.N. Medical college Agra, were included in the study. 52 cases of
traumatic and degenerative conditions were treated by hip joint arthroplasty.  Preoperatively patients were kept on skin or
skeletal traction in cases of trauma, to relieve pain, to check rotation and to
correct the deformity. Patient were educated for quadriceps exercise, gluteal
exercise, toe movement and breathing exercise.

Surgical
technique

34 surgeries were done using the posterior approach and 18
were done using the anterolateral approach to the hip joint .

Posterior
Approach- The incision is started approximately 10 cm distal to the
posterosuperior iliac spine and extended distally and laterally parallel with
the fibers of the gluteus maximus to the posterior margin of the greater
trochanter. Then direct the incision distally 10 to 13 cm parallel with the
femoral shaft. Expose and divide the deep fascia in line with the skin
incision. By blunt dissection, separate the fibers of the gluteus maximus.
Retract the proximal fibers of the gluteus maximus proximally and expose the
greater trochanter. Retract the distal fibers distally and partially divide
their insertion into the linea aspera in line with the distal part of the
incision. Next, expose and divide the gemelli and obturator internus and the
tendon of the piriformis at their insertion on the femur and retract the
muscles medially. The posterior part of the joint capsule was well exposed.
Incise it from distal to proximal along the line of the femoral neck to the rim
of the acetabulum. Detach the distal part of the capsule from the femur. Flex
the thigh and knee by 90°, internally rotate the thigh, and dislocate the hip
posteriorly.

Anterolateral
Approach- The skin and subcutaneous tissue were opened through a
straight longitudinal incision on the center of the greater trochanter. The caudal
half to the trochanter tip was straight; the rest cranial half to the
trochanter tip was curved slightly to the dorsal side of the greater
trochanter. The length of the skin incision varied between 7 and 12 cm,
depending on the physical condition of the patient and the anticipated size of
the implanted components.The fascia lata was divided in line with the skin
incision and centered over the greater trochanter. Tensor fasciae latae divided
anteriorly and the gluteus maximus posteriorly exposing the origin of the vastus
lateralis and the insertion of the gluteus medius. Release the anterior 1/3 of
the abductors, leaving the posterior 2/3 still attached to the trochanter.
Carry the incision proximally in line with the fibers of the gluteus medius at
the junction of the middle and anterior 1/3 of the muscle. Distally, carry the
incision anteriorly in line with the fibers of the vastus lateralis down to
bone along the anterolateral surface of the femur. The neck was exposed. After
making a double door-shaped opening in the capsule, remove the head-neck
fragment in situ or after dislocation.

Postoperative
Care

Ideally, rehabilitation should begin before the operation. A
patient who is motivated and informed and has appropriate goals is better
participant in the rehabilitation process. A preoperative session was used to
teach the appropriate mechanisms for transfers, the use of supportive devices,
dislocation precautions.

Hip extension excercises are encouraged, especially if there
has been a pre-existing flexion deformity. The patient should spend time in the
supine position each day, and pillows beneath the knee are discouraged. The hip
flexures can be stretched early by flexing the opposite hip and maintaining the
operated limb flat on bed(Thomas test).

Partial Weight bearing was done after three days while total
weight bearing was done after 14 days in cemented bipolar and cemented THR.

Skin stitches removed after 12 days. Quadriceps exercise is
mostly initiated 2 to 3 postoperative day while knee bending is done at 6 to 8
postoperative day.

Activities like squatting, cross legs sitting and other
positions which produce repetitive impact loading or extremes of positioning of
the hip are unwise, and the patient should be warned that such activities can
increase the risk of failure of arthroplasty.

Postoperative antibiotics were given. In the immediate
postoperative period, the hip is positioned in approximately 15 degrees of
abduction while the patient is recovering from anaesthetic. We used a
triangular pillow to maintain abduction and prevent extremes of flexion. Drains
are removed 24 to 48 hours after surgery.

Analysis

Fisher exact test and T tests were used. P
