Melorheostosis is a rare, non-inheritable sclerotic bone dysplasia. We report a rare case of a 9 year old male with melorheostosis of carpal bones who presented with pain in right wrist joint on palmar flexion. Plain radiograph and CT performed revealed characteristic appearance of melorheostosis involving the scaphoid, lunate and trapezium. CASE REPORT: A 9 Years old male child presented with complaints of persistent pain in right wrist joint over 1 month with limitation palmar flexion of the wrist. On physical examination terminal palmar and dorsi flexion of the right wrist joint were restricted. Grip strength of right wrist is maintained. There was no significant limitation of daily activities. Plain radiographs revealed hyperostosis of the scaphoid, lunate and trapezium involving both the cortex and medulla. There was no significant periosteal reaction. The carpal joint spaces were maintained. No obvious erosions / lytic lesions were noted. Computed tomography (CT) scans showed a high attenuation involving cortical hyperostosis. Biochemical analysis including serum calcium, phosphorus, alkaline phosphatase, C-reactive protein and erythrocyte sedimentation rate revealed no significant abnormality. A core biopsy was taken from the scaphoid and histopathological analysis revealed nonspecific, dense cortical bone replacing the trabecular system. DISCUSSION: Melorheostosis is a rare non hereditary sclerosing bone dysplasia first described by the two French neurologists Leri and Joanny in 1922¹.The origin of the word melorheostosis is from
Bilateral asymmetric traumatic hip dislocation without an associated fracture of the pelvis or femur occurring in an young adult with no previous history of hip abnormality or ligamentous laxity is a rarity. There were only 58 such cases reported in literature till date. Here is a 28 year old male patient presented to our Department of Orthopaedics and Traumatology, Rangaraya Medical College, Kakinada, Andhrapradesh, India with a history of fall from mango tree with bilateral asymmetric traumatic hip dislocation. The mode if injury is fall from a height. The dislocations were promptly reduced by closed method. Serial follow-up revealed no complications.
