POSTER ABSTRACTS - ISAKOS

up. Results: The mean operating time (153 v 99
minutes), hospital
stay (3.6 v 2.3 days), and return to unrestricted
daily activities (15 v 5.8 weeks) were shorter in
group II. Average time to radiographically evident
fusion was shorter in group I (7.25 weeks v 9
weeks). There was a significant increase in grip
strength and in range of motion at final follow-up
in both groups, and the final grip strength and
range of motion was not different between the
groups. There were no major complications in
either group. Conclusions: Although the number
of patients was small and the follow-up period
was short, arthroscopic scaphocapitate fusion and
capitate pole excision in stage IIIA and IIIB
Kienbo¨ck’s disease resulted in shorter operating
time, shorter hospital
stay, earlier return to unrestricted daily activities,
and equal range of motion and grip strength as
compared with open scaphocapitate fusion and
lunate revascularization. Determination of specific
surgical indications for the benefits of
arthroscopic treatment of Kienbo¨ck’s disease
must be analyzed in larger studies.

A New Technique for Reconstruction of the
MCL of the Elbow Using Triceps Tendon

Presentation of short term results after
reconstruction of the Medial Collateral Ligament
of the elbow using the ipsi-lateral triceps tendon.
In this study ten patients are described with a
medial instability of the elbow joint due to
insufficiency of the medial collateral ligament.
History and findings at physical and radiological
examination are presented. All underwent
reconstruction of the anterior part of MCL using I
one third of the ipsi-lateral triceps-tendon.
Follow-up took place 4 months- 1.5 year after
surgery including the EFA and Morrey scoring
system Reconstruction of the MCL using
ipsiplateral triceps tendon or refixation of the
MCL of the elbow joint gives satisfactory results in
throwing athletes. Eight patients regained full
range of motion, two had an extension deficit of
10 . Two patients had a transient sensory ulnar
nerve symptoms. All patients but one were able
to return to their previous level of athletics.
Reconstruction of the MCL using ipsilateral
triceps tendon or refixation of the MCL of the
elbow joint gives satisfactory results in throwing
athletes.

Distal Biceps Tendon Anatomy and Endoscopy

INTRODUCTION
The detailed anatomy of the distal biceps tendon
as yet to be defined. The clinical assessment of
partial tears of the biceps tendon is difficult to
visualise intra-operatively.
MATERIAL AND METHOD
Using cadaveric and clinical models we have
reviewed the anatomy of the distal biceps tendon
and its bursa. We have developed an anterior
cubital fossa portal to allow assessment of the
distal biceps tendon.
RESULTS
The distal biceps tendon can be shown to be two
distinct tendons. Each is a continuation of the
short and long head muscle bellies. The tendon
may also be visualised and debrided through the
anterior cubital portal.
CONCLUSION
The distal biceps tendon has two portions, one
acting as a supinator and the other a flexor of the
forearm. These two tendons represent the muscle
bellies of the long and short heads of the biceps.
The cubital portal allows endoscopic assessment
of the tendon and debridement of partial tears.
The new portal can also be as an anterior elbow
portal.

Aim
Kinematic and morphologic evidence suggests
that the scaphoid may be moved differently
between individuals. This study therefore aims to
determine to what extent the morphology and
ligamentous support of the scaphoid supports the
