Introduction: Tunnel enlargement following anterior cruciate ligament (ACL) reconstruction has been frequently reported since the nineties, yet its etiologies remain unclear.

Aim: To elucidate the factors favoring this phenomenon and to investigate its clinical and anatomical consequences.

Methods: This was a descriptive retrospective study conducted on 37 patients who underwent ACL reconstruction surgery using single-bundle hamstring tendons with fixation using absorbable interference screws at the Traumatology Department of the Kassab National Institute of Orthopedics.

Cavernous hemangioma of the forearm muscles: Three case reports and literature review.

Introduction: Hemangiomas are common benign vascular tumors. Intramuscular hemangioma is a very rare type of hemangioma occurring in the skeletal muscle. The lower limb muscles are more likely to be affected.

Solitary plasmocytoma of the thoracic spine: A case report.

Introduction And Importance: Solitary spinal plasmacytoma (SSP) is an uncommon neoplasm originating from bone marrow plasma cells. Although infrequent in the thoracic region, it has the potential to induce substantial damage. In this study, we present the case of a patient with thoracic spine SSP treated through surgical intervention.

About a rare cause of calf pain in an athlete: the popliteal artery entrapment syndrome (a case report).

Claudication of the young patient is a very rare symptom for orthopaedic surgeons and it is often overlooked. We report a rare case of popliteal artery entrapment syndrome (PAES), discovered during a vascular claudication following post-traumatic anterior instability of the knee. The diagnosis was confirmed by CT angiography which showed a PAES, with a pathway in the inter-condylar notch.
