sparing surgery in the extremities – preliminary re-
sults

Department of Orthopaedic Surgery, Sarcoma Center at Aarhus University
Hospital, Aarhus, Denmark;
Background and purpose:
Only few studies have investigated strength in soft
tissue sarcoma patients by using objective measurements.
Purpose:
This study intends to determine the effects of limb-sparing surgery
on the functional outcome measured by strength at the first 3 months in soft
tissue sarcoma patients.
Methods:
Patients who underwent surgery for a soft tissue sarcoma in the
extremities at Aarhus University Hospital were included. Patients with dis-
seminated disease or patients who had undergone replacement surgery in the
disease-affected extremity were excluded. Patients completed a dynometric
muscle test with the Biodex System 3 dynamometer before surgery, 1 month
and 3 months after surgery on both the disease-affected and healthy side. The
results were compared to normative data. A percentage between the obtained
value compared to the expected value was calculated.
Results:
This study included 25 patients who completed pre-operative mea-
surement, while 13 patients completed 1 months and 3 months after surgery
measurement. There was no significant difference found between healthy and
disease-affected side pre-operatively and 3 months after surgery (p=0.57 and
p=0.10, respectively). However, 1 month after surgery the healthy side was
significantly stronger (p<0.01). Before surgery patients had a mean strength
on 78.96% of the expected (95%-CI: 72.11-85.81). 1 month after surgery,
they had a mean strength on 77.90% of the expected (95%-CI: 68.46-87.34).
While 3 months after surgery patients had a mean strength of 77.48% of the
expected (95%-CI: 65.46-89.49).
Conclusion:
We did not find any significant difference in function, measured
by the dynamometer, between the disease-affected side and the healthy side
after 3 months. However, soft-tissue sarcoma patients have significant reduced
strength when compared to healthy people.
