Reconstruction using monorail fixator for forearm osteochondroma Masada type I and IIb: A case series.

INTRODUCTION: Osteochondroma (solitary) and multiple hereditary exostoses (plural) are defined as a cartilage-capped bony projection arising on the external surface of bone containing a marrow cavity that is continuous with that of the underlying bone. These tumors grow slowly and develop to cause symptoms such as limited range of motion, joint pain, lumps, and deformities. The use of ulnar distraction osteogenesis has gained popularity in treating deformity in forearm osteochondroma. Problems that arise including bone angulation and persistent radial head dislocation. CASE PRESENTATION: We describe eight cases of forearm osteochondroma that came to the Prof. Dr. R. Soeharso Orthopedic Hospital, Surakarta, Indonesia. We found two variations in the classification of Masada in these 8 patients, Masada type I and IIB. The main complaint was a bent arm. We decided to do surgery in the form of tumor resection and reconstruction of the deformity by using ulnar gradual lengthening and osteotomies. The results of the procedure were investigated in this study, using clinical and radiological parameters focusing on medium-term functional and structural outcomes. DISCUSSION AND CONCLUSION: Eight patients had overall good results, although performed with a different sequence of operating techniques. Ulnar lengthening with a monorail fixator is still the main choice in its implementation. Gradual ulnar lengthening improves not only the deformity but also the functionality of the associated forearm.

Bilateral Congenital Absence of Femur: A Rare Case Report.

INTRODUCTION: Bilateral congenital absence of femur is a rare congenital anomaly. CASE REPORT: We report a 2-year-old Indonesian female child, the third of the birth of diabetic mother. There is no congenital abnormality among her siblings. She has a normal mentality and normal upper limbs. She was brought to us with a complaint of the short lower limb. Examination revealed short lower limb with an absence of thigh, a full range of motion of the hip and ankle and left club foot. A detailed history was obtained and she was radiologically examined. The X-ray of the pelvis and lower limb shows shallow of the acetabulum, absence of bilateral femur, and uncommon form of tibia fibula. She was diagnosed with bilateral congenital absence of femur. CONCLUSION: We report this case because it does not meet the existing classification criteria for congenital femur deficiency. Proper evaluation and management of this case can help the patient and the parents to accept her condition and be able to live a good social and economically productive life.
