Osteosynthesis of an intertrochanteric fracture on osteopetrosis A case report

INTRODUCTION

Osteopetrosis is a rare hereditary disease that can be transmitted in an autosomal recessive or autosomal dominant.

CASE REPORT

Here, we report a case of trochanteric fracture in an 18-year-old boy with an anatomical plate. At the last follow-up, 24 months after surgery, the fracture had healed well, and the patient was not restricted in his activities.

DISCUSSION

Osteopetrosis is a rare bone disease that is mainly caused by osteoclast dysfunction. It results from a remodelling defect that leads to hypermineralization of the skeleton, resulting in bone fragility. Both surgical and nonsurgical management have advantages and disadvantages. Thus, open reduction and anatomic plate fixation remain effective management modalities for trochanteric fractures in osteopetrosis patients.

CONCLUSION

For our patient and as described in the literature, the complication rate decreases as some principles are respected with better consolidation of the osteoporotic fracture.

Osteopetrosis: Discovery and early history of "marble bone disease"

Discovery in 1904 of the disorder initially called "marble bones", then in 1926 more appropriately referred to as "osteopetrosis", is attributed to Heinrich E. Albers-Schönberg (1865-1921), the first radiologist. He used the new technique of Röntgenography to report in a young man the radiographic hallmarks of this osteopathy. Clinical descriptions of lethal forms of osteopetrosis had apparently been published earlier by others. Here, I review the discovery and early understanding of osteopetrosis. Characterization of this disorder commencing at the beginning of the past century would support the aphorism of Sir William Osler (1849-1919): "Clinics Are Laboratories; Laboratories Of The Highest Order". As featured in this special issue of Bone, the osteopetroses would prove remarkably informative about the formation and function of the cells responsible for skeletal resorption.

[A rare case of bilateral femoral neck fracture in a 5-year-old girl with autosomal dominant osteopetrosis type 2]

The rare case of a 5‑year-old girl with autosomal dominant osteopetrosis type 2, who suffered metaphyseal fractures of the femoral neck on both sides within 6 months is described. On the right side, the diagnosis was made 3 months after the onset of symptoms, so that a coxa vara occurred. The treatment was surgically treated through a valgus osteotomy with fixation of the femoral head with K‑wires. Three months after the operation, the girl complained of a painful restriction of movement on her left side. Radiologically, a metaphyseal femoral neck fracture without coxa vara was diagnosed and in situ fixated with 2 K wires. Two months after the second operation, there was a symmetrical free range of motion of the hips with no symptoms. The metaphyseal femoral neck fracture with verticalization of the growth plate is a serious disease in autosomal dominant osteopetrosis due to the development of a coxa vara, which, if diagnosed at an early stage, can be treated well with in situ fixation. If the coxa vara has already developed, a valgus osteotomy should be performed despite the risk of delayed bone healing.

Osteopetrosis (Marble Bone Disease): A Rare Disease in Children

Osteopetrosis is a group of diseases that affects the growth and remodeling of bone and characterized by over growth and sclerosis of bone, with thickening of the bony cortices, abnormal dental development and narrowing of the marrow cavities throughout the skeleton. It is an uncommon disease of unknown cause. A 5-year-old boy was suffering from infantile (severe form) osteopetrosis with cardiac enlargement, severe anemia, hepatosplenomagaly and radiographs showed generalized increase in bone density (chalky white), narrowing of skull base is reported here.

Infantile osteomyelitis secondary to malignant osteopetrosis

Osteopetrosis (OP) is a rare congenital disorder (present at birth) in which the bones become over dense. This results from an imbalance between the formation of bone and the resorption of the bone. Thickening of the bones which become abnormally dense due to an inherited defect in bone resorption, the process in which old bone is broken down and removed so that new bone can be added to the skeleton. Osteoclasts are the cells responsible for bone resorption. In osteopetrosis the osteoclasts do not perform normally. This flaw in bone resorption results in bones that are abnormally dense, yet are fragile and easily broken. Osteopetrosis is also known as Albers-Schonberg disease, generalized congenital osteosclerosis, ivory bones, marble bones, osteosclerosis fragilis generalisata. In this article, we have described about the diagnosis and medical and surgical management of osteopetrosis reported case to our hospital.
