STUDY DESIGN: Prospective clinical case series.

OBJECTIVE:

-To evaluate the clinical outcome of anterior endoscopic instrumention for scoliosis using the Scoliosis Research Society(SRS) -24 questionnaire.

-To examine how these scores change over a 2-year follow-up period.

SUMMARY OF BACKGROUND DATA:  

The clinical results of Anterior endoscopic instrumentation correction using a validated 

outcome measure have rarely been reported in the literature.

METHODS:

▶Subject number: 83 consecutive patients (74 females + 9 males)

▶Inclusion criteria: 

underwent endoscopic anterior instrumented fusion for scoliosis using a single rod technique. (period: 2000.04~2005.01)

▶Surgical technique: 

To perform anterior scoliosis instrumentation and fusion via an endoscopic approach.

▶Clinical outcomes evaluation: To assessed before surgery and at 3, 6, 12, 24 months after surgery using the SRS-24 questionnaire.

▶Radiographic evaluation: 

The major Cobb angle was measured using the cobb method at all review appointments

▶Statistical analysis: using SPSS software, Mann-Whitney test.

RESULTS:

▶Clinical outcomes evaluation:

-Evaluated clinical outcomes(using SRS-24) are listed belows.

-Changes of SRS-24 scores VS time during (preop, 3,6,12,24 months) graph

-->The graph showed that the greatest improvement in function occurred between 6 and 12 months after surgery.

▶Radiographic evaluation:

-Mean coronal Cobb angle: 52.6° (preop) --> 21.7° (postop)

CONCLUSIONS:  

-Endoscopic anterior instrumentation for scoliosis significantly improved pain, self-image, and function.

-The SRS-24 scores at 1 year from surgery may provide a good indicator of patient outcome in the long-term.

Key points:

● Endoscopic anterior instrumentation for scoliosis significantly improved pain, self-image, and

function when assessed using the SRS-24 Outcome Instrument.

● Activity level improved between 3 and 6months, whereas function from back condition and postoperative function domains improved between 6 and 12 months after surgery.

● No further improvement occurred in any of the SRS-24 domains after 1 year, and these scores may provide a good indicator of patient outcome in the long-term.
