POSTER ABSTRACTS - ISAKOS

Due to difficulties on passing PDS sutures in the
anchors knot this is a method with a large
learning curve. Besides, it improves the
arthroscopic capablity of tightening lax and fragile
capsules and as we can bite thinner capsule
without loosing fixation because larger amount of
sutures are used.

Purpose:
The purpose of
this presentation is to establish the relationship
between shoulder instability or micro instability,
and Rotator Cuff lesions.
Materials and method: The study involved
young sportsmen and the cases were selected
according to pre-defined inclusion criteria.
Sportsmen, younger than 40 years of age, lesions
associated to instability, with and without
dislocation were selected.
The classification used was the following: Grade I
or Hemorrhagic; Grade II or Fibrous; Grade III or
Rupture (Total-Partial; Bursal-Articular)
Diagnosis, treatment and arthroscopic options are
analyzed, according to the degree of Rotator Cuff
lesions and joint instability. Thirty-seven patients
and their results were studied.
Conclusions:
It was concluded
that the etiology of the rotator cuff lesions should
be further studied in order to perform combined
bursal and intra-articular treatments, so as to
decrease the incidence of poor results and postop
recurrences in this pathology frequently found
in sportsmen.

Severe Recurrent Posterior Instability - New
Technique - Infraspinatus Advancement to the
Posterior Glenoid

Introduction The treatment of recurrent posterior
instability of the glenohumeral joint continues to
be a challenge. Higher failures rates than with
anterior stabilization procedures may result from
misdiagnosis or when not all the pathologic
conditions are well addressed. Higher failure rates
are found in shoulders with ligament hyperlaxity
and capsular deficiency. For these types of
shoulders we describe an arthroscopic technique
that consists of: Labrum repair, capsular plication,
rotator interval closure and advancement of the
infraspinatus as a graft to the posterior glenoid.
We describe a case series study.
Material and Methods From years 1999-2003 we
performed this operation to 10 shoulders, At the
time of final evaluation 5 patients had at least 2
years of follow up. 4 men and 1 woman. Mean age
was 31.5 ( range 18-55 ) There were no
professional athletes. 2 patients had reverse
Bankart lesion. 4 patients had a MDI 1 patient had
a significant traumatic episode (convulsion) The
capsule was deficient in all cases. Labrum repair
was done in 2 patients. Posterior capsular
plication was done in all as well as rotator interval
closure. Anterior capsular plication was done in
the 4 MDI patients. Advancement of the
infraspinatus to the posterior glenoid was done in
all patients. The mean preoperative ASES score
was 30 points and improved to a mean of 55
points postoperative. There was significant
reduction of humeral translation in all patients.
Internal rotation was reduced in all but there
wasn’t a significant restriction and were able to
work normally. There were no dislocation
recurrences. 1 patient complained of posterior
pain after 2 years post surgery. Conclusion We
suggest that this procedure is effective for treating
severe recurrent posterior instability associated
with capsular deficiency and hyperlaxity. Severe
posterior instability is a relatively rare entity.
Longer follow up is needed
