POSTER ABSTRACTS - ISAKOS

Methods: The study was prospective and
consecutive. 29 multiply injured patients with 33
supracondylar fractures were treated with a
retrograde femoral nail between May 1994 and
November 1998. There were 15 A (45%) extraarticular
and 18 C (55%) intra-articular in 12 men
and 17 women with an average age of 61 (range
16-96). There were 9 (27%) open fractures (3 grade
II, 2 IIIA, 4 IIIB) and 24 (63%) were closed. The
Main Outcome Measures were: Fracture pattern,
surgical procedure, operative blood loss and time,
incidence of hardware failure, misalignment,
healing rate and time, post-operative range of
motion, long term effects and follow up.
Results: There were 6 (18%) trans patellar tendon
and 27 (82%) Para patellar approaches. Open
fractures were treated after debridement. The
average blood loss was 250 cubic centimetres; the
average time procedure was 150 minutes. There
were no bone graft, no hardware failure, and no
infection. There were 4 misalignments (2 valgus, 1
varus, 1 shortening). All the patients healed. The
average time to union was 12 weeks (range 10-20).
The average range of motion was 110 degrees
(range 60-130). The mean follow up was 100
months. The results were consolidated and no
complications were observed once the first year
after trauma is achieved.
Conclusion: The results suggest that retrograde
supracondylar nailing is a versatile technique that
lends itself to a variety of femoral fractures
applications. The rate of union and infection, the
ranges of motion are associated with a closed,
biological surgical technique. The long term
results confirm our initial choices.

We report the case of huge intra-articular benign
fibrous histiocytoma of the knee joint in a 40 yearold
woman.
The patient presented at our hospital exhibited
pain and difficulty achieving full extension in her
right knee. Physical examination revealed
swelling on the lateral side of the knee. The range
of motion of the joint was slight extension block
but flexion was no restriction. Plain radiograph
showed an unremarkable. MRI showed a large
intra-articular mass in the region of the anterolateral
side of the knee joint. The T-1 weighted
image showed a nodular mass of inhomogeneous
hypointensity and heterogeneous dark and high
signal intensities were shown on the T-2 weighted
image.
Following the diagnostic work, arthroscopy was
carry out. A large oval shape floating mass(5cm x
3cm x 2.5cm) rooted with small rope like cord on
the lateral side of the patellar tendon was found
but other structures of the joint were found to be
intact. An arthrotomy involving an incision 5-cm
long was made on just the lateral side of the
patellar tendon. An ovoid, firm tumor was
removed.
Histopathological investigation revealed a
fibrohistiocytic tumor, composed of spindle cells,
some giant cells, histiocyte and foamy histiocyte.
The pathological diagnosis was benign fibrous
histiocytoma.
At the one year postoperative follow up, the
patient was free of pain and without functional
disability.

Purpose: Our aim was to determine the outcome
of arthroscopic reduction and internal fixation for
the treatment of tibial plateau fractures. Type of
study: Case series. Methods: 11 consecutive
patients (4 men, 7 women) with tibial plateau
fractures were enrolled in this study. The average
age at surgery was 48 years (range, 18 to 75 years).
The follow-up period ranged from 12 to 18
months, with an average of 14 months. Using the
Schatzker classification, there were 5 type-2, 4
type-3 and 2 type-6 fractures. Type-2 and type-6
patients underwent arthroscopic-assisted open
reduction and screw fixation or plate fixation.
Type-3 patients underwent arthroscopic reduction
and percutaneous screw fixation. In this procedure
for type-3 patients, we used ACL tibial guide and
coring reamer to manipulate depressed bone
fragments and grafted iliac bone core to the defect
and fixed it percutaneously by screws. 9 (82%)
patients had associated intraarticular injuries that
was diagnosed and treated arthroscopically. There
were eight lateral meniscal tears, one chronic
