  • Past research has reported that the common causes of ankle arthritis include trauma, congenital deformity, and degeneration. Among them, fracture-induced post-traumatic arthritis is most common. For patients with ankle fractures, an anatomical reduction is performed through surgical treatment. However, insufficient reduction or malunion of the fracture site may change the alignment of the ankle joint, resulting in valgus or varus deformities. Currently, most operative options for valgus arthritis aim to either restore joint alignment and/or reduce the uneven load on the cartilage. In this report, we would like to share our clinical experience of a patient with posttraumatic valgus ankle arthritis caused by severely comminuted fracture and dislocation. A satisfactory outcome could be obtained with combined fibular lengthening osteotomy and medial displacement calcaneal osteotomy.

  • During long bone lengthening, there are many disadvantages including axial deviation, malalignment and re-fracture which are commonly encountered inspite of its proven abilities. To study the effects of intramedullary K-wire application on the lengthening of long bone, ten skeletally mature mongrel dogs were separated into two groups(Group I, II). Right femurs of group I(5 dogs) were fixed with only monolateral external fixator after subperiosteal osteotomy. Right femurs of group II(5 dogs) were fixed with mono lateral external fixator and intramedullary K-wire after subperiosteal osteotomy. Lengthening was started at 7 days after the surgery with the rate of 0.5 mm per day for 5 weeks and the dogs were sacrificed after 15 weeks postoperatively to examine histologic differences and evaluate bone mineral density. Radiographic examination at an interval of two weeks was done to evaluate the type of callus formed and to analyze complications including instability of external skeletal fixation and axial deviation. Bone mineral density at the lengthened area and contralateral nonlengthened area were measured using quantitative computerized tomography. Histological examination of regenerated bone was performed using Masson's trichrome stain method. The radiographs demonstrated poor callus formation, higher incidence of axial deviation and screw loosening in the group I compared to the group II. The bone mineral density at the lengthened area in the group II was higher than that of the group I(P<0.05). Histological examination showed that the new bone trabeculae in the group II were greater than that of the group I. In conclusion, the combination of monolateral external fixator and intramedullary K-wire can prevent pin loosening, axial deviation and reduce healing period in dogs.

  • A wide variety of deformities can occur following repair of the cleft lip. Especially, cleft lip nasal deformities offer the severe psychologic, esthetic, and functional impairment. We must restore the deformities of alar cartilge, nasal tip, septum, columella, or pyriform aperture. The authors reconstructed the cleft lip nasal deformities using with the alar cartilage rearrangement, postauricular cartilage graft, and/or columellar lengthening. The 3 case reports are presented.
