Goals: A prospective analysis of arthroscopic
subacromial decompression (ASD) associated to
rotator cuff repairing by mini-open technique vs.
arthroscopic technique in 48 and 64 respective
cases operated between December 1997 and April
2003.
Material and method: 112 patients were reviewed.
42 patients (48 cases) were operated with the
mini-open procedure and arthroscopy (group 1) y
59 patients (64 cases) were operated with a total
arthroscopic procedure (group 2). The same
model of implant was used in both groups, and
surgery consisted in bursectomy, coracoacromial
ligament resection, acromioplasty, and rotator
cuff tendon fixation with titanium implants of
non-absorbable sutures. Clinical results were
compared in both techniques by CONSTANT and
UCLA scales.
Results: follow-up in group one was of 16
months. Pain and mobilisation improved in 80%
of patients, in both clinical scales.
Follow-up in group two was of 9 months.
Pain and mobilisation improved in 90% of
patients. There were no complications.
Altogether, 84% of patients showed complete
satisfaction after surgery. Statistical differences
between groups were not found related to clinical
and functional recovery.
Conclusions: Rotator cuff repair by
arthroscopic technique and /or mini-open
procedures has become a common surgical
procedure in shoulder surgery and makes open
classic procedures as a method of treatment of
the past.

The purpose of this study was to identify the
attachment sites, clavicle osteology and bending
strength of the distal clavicle, for a new anatomic
reconstruction of the coraclavicular ligaments
(ACCR). The new technique required two tunnels
placed in the distal clavicle. Therefore, the
bending strength after creation of a single and
double tunnel reconstruction was also evaluated.
118 Clavicles (48.3+16.6 yrs) were analyzed and
used for osteologic measurements. 14 fresh frozen
cadavers (72.8+1.3.4 yrs) had bone density
measurements, were potted and distributed into
one of four tunnel configuration groups and
subjected to a 3-point cantilever load at 12.7
mm/min.
There was no correlation between bone density
and ultimate load. There was no difference
(p=0.3) in ultimate failure between intact, single
tunnel (Arthroscopic AR 4.0mm), two tunnel
(ACCR 5.5mm), and 4 drill hole techniques
(Weaver-Dunn WD). The mean length to the
coraclavicular ligaments was 46.3+5.2 mm. The
anterior/posterior clavicle thickness was
(19.1+2.9mm), the superior/inferior thickness was
(11.5+1.6mm) and the distance between the CC
ligaments was (21.4+4.2mm).
This study demonstrates that the placement of
two 5.5mm tunnels for the anatomic
reconstruction of the CC ligaments does not
decrease ultimate failure load of the distal
clavicle. The osteology will promote accurate
anatomic coracoclavicular reconstructions.
