Shoulder Hemiarthroplasty In Patients With Juvenile Idiopathic
Arthritis
Replacement of the berm in juvenile person idiopathic arthritis
is not often performed and at that place rich person been no
published series to date. We present nine glenohumeral
hemiarthroplasties in eight patients with systemic or
polyarticular adolescent idiopathic arthritis. The mean keep
up-up was six days (59 to 89 months). The mean age at the time
of operation was 32 old age. Surgery took place at a mean of 27
age subsequently diagnosis.
The results indicated excellent easing from painful sensation.
At that place was restoration of useful office which
deteriorated with time, in part because of progression of the
systemic disease in this severely affected group. No patient has
required revision to date and in that location has been no
radiological evidence of laxation or osteolysis around the
implants. We discuss the pathoanatomical challenges unique to
this group. In that location was very little space for a
prosthetic marijuana cigarette and, in some cases, bony
deformity and the belittled size necessitated the wont of
custom-made implants.
Arthritis of the shoulder joint is rarely an early feature of
jejune idiopathic arthritis. Involvement of the hip joint and
stifle is more common and can be treated by arthroplasty.'~8
That of the articulatio humeri is seen later in the course of
ongoing systemic or polyarticular puerile idiopathic arthritis
with an incidence of 15% at 15 eld from the onset of the
disease.9 Persistent arthritis of the immature produces a
maldeveloped proximal humerus and glenoid cavity (Fig. Later in
the course of the disease, erosion of ivory and cartilage
whitethorn cause medial migration and superior subluxation of
the humeral head. Consequent dysfunction of the impairs basic
daily activities such as toileting and the utilization of
crutches or a stick, which English hawthorn be required during
rehabilitation later surgical operation on the coxa or knee
joint.
If the elbows become involved, the role of the upper limb
deteriorates further. Another (case 6) complained of persistent
paraesthesiae and annoyance affecting the lateral aspect of her
forearm afterwards surgical procedure which did not respond to
simple analgesia and physiotherapy. She remains unable to
self-toilet effectively because of a poor range of movement and
her purpose has deteriorated with time. Peripheral
nerve-conduction studies were comparable with those of the
contralateral arm and within normal limits. MRI of her cervical
spine showed degenerative changes consistent with a C6
radiculopathy, merely she has declined further intervention.
Thither wealthy person been no other significant complications
to date. This is a diminished series of patients with no
unoperated control group other than the contralateral of four
patients with significant arthritic involvement. Our methodology
is otherwise reasonable.
