Abstract: Anterior shoulder dislocation is a very common trauma
and the main complications are well documented.
We report a case of aseptic osteonecrosis of the
humeral head following an isolated episode of anterior
glenohumeral dislocation without fracture that, to
our knowledge, has never been reported in the literature.
A 17-year-old male patient sustained an anterior glenohumeral
dislocation following a sport accident. It was
managed by reduction and immobilization. A radiologically
identified aseptic osteonecrosis appeared
6 months later. The instability had been arthroscopically
treated. At a follow-up of 4 years, the osteonecrosis
has been stabilized leaving a mild arthrosis with
stiffness, but without pain.
Abstract: Summary This study is a synthesis of three series. The first study was prospective on
418 patients with an anterior cruciate ligament (ACL) tear (group I). Two population of ACL
ruptures were identified. One population with a postero-lateral bundle preserved in 16%, the
mean medial anterior tibial translation side to side was 4.97mm, the Lachman test was delayed
in 40% with no or glide pivot shift in 73%. The second population with a complete ACL tear had
a mean medial anterior tibial translation side to side of 7.93 mm, the Lachman test was soft in
98% with gross pivot shift in 80%. The second study was a retrospective study on 258 patients
(group II) at 26 months follow-up, it correlated the impact of the type of graft on the clinical
objective and subjective results. Twenty-eight percent had anterior knee pain, 33% for the
patellar tendon and 25% for the hamstrings, the subjective IKDC was significantly lower for the
painful knees, and 68% of the patellar tendon had a hypoesthesia and only 32% for the hamstrings.
The ability to walk on the knee was 68% for the hamstrings and 35% for the patellar
tendon. The third study was retrospective on 127 patients, 24 months after ACL reconstruction
(group III), all were tested on a isokinetic machine for the extensor, the flexor and the internal
rotator. In the total population, a 10% extensor and flexor deficit and a 5% rotator deficit was
noted. A significant difference between patellar tendon and hamstrings in terms of muscular
recovery was found. It pointed out that a more specific rehabilitation should be done on the
hamstring group. The muscular recovery was correlated to the highest subjective score. This
study allowed the surgeon to be more specific in the ACL tear definition, to adapt the graft
choice to the type of sport activity but also to the type of work the
