Tibial tubercle avulsion fractures in school sports injury: A case report.

INTRODUCTION: Most injuries in adolescent occur during school sports like volleyball, football or basketball. Tibial tubercle avulsion fractures (TTAF) are an unusual condition, resulting from a forced extension of the knee opposed to fixed leg. PRESENTATION OF THE CASE: A 16 years old male was hurt during school basketball, X-rays displayed avulsion fracture of tibial tuberosity of left knee, the treatment was operative using two cancellous screws, results were good including complete knee mobility and early coming back to school sport at 6 months. DISCUSSION: TTAF remains rare accounting for <3% of all epiphyseal injuries, it is frequent in teenage boys with open physis during school sport. We review the pathophysiology, mechanism, classification, diagnosis, and management of this injury. CONCLUSION: complications are occasional and functional recuperation is common after closed reduction and cast immobilization for slightly or no displaced fractures, otherwise open reduction and internal fixation for displaced fractures.

Myxoid chondrosarcoma extraskeletal in pelvis location : a case report.

BACKGROUND: The extraskeletal myxoid chondrosarcoma (CME) is a rare tumor of the soft tissue, with clinically distinguishable clinical, histological, immunohistochemical, cytogenetic and evolutionary characteristics with an unfavorable long-term prognosis. CASE: We reported the case of a young patient of 18 years, accusing pelvic pain for 5 months with a poor general condition, an MRI was performed immediately, objective infiltrative mass endopelvic evoking several etiologies. The histology of the biopsy extraskeletal myxoid chondrosarcoma reveals a (CME). 's Staging came back normal. We performed an incomplete surgical resection due to the deep location of the pelvis in the tumor followed by radiotherapy. CONCLUSION: The CME is a tumor diagnosis very difficult and often delayed, despite a mostly local aggressiveness and prolonged survival, it is considered a low-grade sarcoma malignancy or intermediate malignancy. Treatment consists of complete surgical resection with a potential adjuvant radiotherapy . Chemotherapy is not very effective.

Osteoid osteoma of the acetabular roof: a case report.

BACKGROUND: An acetabular location of osteoid osteoma is rare and represents less than 1 % of cases. The purpose of this clinical case report is to highlight the unusual location of osteoid osteoma and the technical difficulty of its removal. CASE PRESENTATION: We report a case of a 17-year-old Moroccan Arab boy who presented with pain in his right hip with lameness. The diagnosis of osteoid osteoma was made by imagery and confirmed by histological examination. The treatment consisted of a complete percutaneous resection scanno-guided of the nidus. The evolution was marked by complete healing with total and definitive disappearance of symptoms after 1 year. CONCLUSIONS: Osteoid osteoma of the acetabular roof is rare. The diagnosis is now easy because of the evolution of imaging. Treatment is exclusively surgical. Complete resection guarantees the absence of recurrence. The difficulty of the surgical procedure is due to the deep localization of the osteoid osteoma and because it is endosseous, it is also dangerous due to anatomical relationships and the small size of the osteoid osteoma.

Munchausen syndrome revealed by subcutaneous limb emphysema: a case report.

INTRODUCTION: Limb subcutaneous emphysema secondary to a Munchausen syndrome represents a rare and severe entity because it involves the functional prognosis of the limb and vital prognosis of the patient. CASE PRESENTATION: We report the case of an 18-year-old Moroccan woman patient who presented to our hospital with a subcutaneous emphysema of the shoulder girdle and the right arm, caused by our patient. Treatment was aggressive, with a wide surgical debridement, parenteral antibiotic therapy and hyperbaric oxygen therapy. The results have been favorable. CONCLUSIONS: The correlation of anamnestic data and clinical and para-clinical exams were essential for the diagnosis of Munchausen syndrome in this case. In this regard, we report a rare case of subcutaneous limb emphysema secondary to Munchausen syndrome.
