POSTER ABSTRACTS - ISAKOS

technique was valid and reproducible.
Conclusion: The lateral capsular shift resulted in
significantly greater volume reduction when
compared to arthroscopic plication. Based on
these results we recommend an open lateral
based capsular shift for patients with
multidirectional instability and a large patulous
shoulder capsule. The amount of volume
reduction required to eliminate instability still
remains unknown for patients with shoulder
instability due to capsular laxity.

Objectives:
Operative time (OT) is costly. We wanted to define
whether OT was saved when switching to
arthroscopic shoulder instability treatment (ASIT)
and compare with open shoulder instability
treatment (OSIT).
Methods:
From 1997 to 2003 a single fellowship trained
surgeon performed 91 SIT’s. There were 57 ASIT’s
and 34 OSIT’s. During all cases, nursing staff
independently recorded cut to close times. This
defined the individual OT. A surgical information
services administrator independently queried the
operative cases and provided the final data set.
Statistical analysis was performed on the results.
Results:
Over the period evaluated, the surgeon
transitioned from OSIT to ASIT gradually. The
average OT in OSIT cases was 161 minutes. The
average OT in ASIT cases was 88 minutes. An
Independent t-test was used to compare OSIT and
ASIT OT. The scope group's procedure time was
significantly lower than the open group (p
