Long-Term Result of Mosaicplasty for Femoral Head Osteochondral Lesion: A Case Report with 8 Years Follow-up

AbstractThe aim of the present study was to present clinical and radiological outcome of a hip fracture-dislocation of the femoral head treated with biomimetic osteochondral scaffold.An 18-year-old male was admitted to the hospital after a motorcycle-accident. He presented with an obturator hip dislocation with a type IVA femoral head fracture according to Brumback classification system. The patient underwent surgery 5 days after accident. The largest osteochondral fragment was reduced and stabilized with 2 screws, and the small fragments were removed. The residual osteochondral area was replaced by a biomimetic nanostructured osteochondral scaffold. At 1-year follow-up the patient did not complain of hip pain and could walk without limp. At 2-year follow-up he was able to run with no pain and he returned to practice sports. Repeated radiographs and magnetic resonance imaging studies of the hip showed no signs of osteoarthritis or evidence of avascular necrosis. A hyaline-like signal on the surface of the scaffold was observed with restoration of the articular surface and progressive decrease of the subchondral edema.The results of the present study showed that the biomimetic nanostructured osteochondral scaffold could be a promising and safe option for the treatment of traumatic osteochondral lesions of the femoral head.Study Design: Case report.

Tooth Inclination

The long term result of orthodontic extractions of mandibular second premolars and permanent first molars was investigated by measuring the degree of tooth tipping mesial and distal to the extraction sites in cases with complete and incomplete closure of extraction spaces after treatment and/or at follow-up examination. Tooth inclination was determined from photographs taken of dental casts made after treatment and follow-up examination. The inclination of the teeth was measured in relation to each other and in relation to the occlusal line. The results of the investigation revealed that teeth which were tipped mesial and/or distal to the extraction sites after orthodontic treatment had a tendency to upright in relation to each other and in relation to the occlusal line. Uprighting was pronounced in cases which had extraction spaces remaining after treatment, but which were closed at the time of follow-up examination, and in cases with closed extraction spaces after treatment. However, minimal changes in inclination of the teeth adjacent to the extraction sites were found in cases with incomplete space closure after treatment and at follow-up.
