The frequency of infected non-union of long bones is increased due to an increment of open fractures, and so its treatment give orthopedic surgeons a rather difficult obstacles. In treatment of twenty two cases of trouble infected non-union that we undergone from march, 1980 to decmber, 1984, we use some principles of treatment, that is, rigid osteosynthesis, autogenous cancellous bone graft and irrigation system, so we obtain the good results. The conclusion are as follows: 1. All cases were men, and they occured more commonly in young adults, 10 cases (45.5%) were in third decade. 2. The fractures of the tibia showed a high frequency of infected non-union, 17 cases (77.3%) were the fractures of the tibia. 3. All cases showed a grave comminution initially, of them 18 cases (81.8%) were open fractures. 4. The most common causative organism of an infection was staphylococcus aureus, 14 cases(63.6%), showed that organism in pus culture. 5. Using the above mentioned principles of treatment, bony union was achieved in 18 cases for average 5 months except 2 cases losting the follow-up and 2 cases undergoing the below knee amputation.

Normal sectional anatomy of the calcaneus with multiplanar CT examination was studied in 5 volunteers as thebackground for interpretation of various abnormalities. Major 3 sectional anatomy including plantar, coronal,sagittal and additional tuberosity planes are described. With CT examination of the calcaneus, 1. More detailedanatomy of 3 facets of subtalar joint(anterior, middle, and posterior facet) can be well visualized. 2. Itsclinical applications in the tarsal trauma, tarsal coalition, subtalar infectin, degenerative arthritis, clubfoot, pes planus and tarsal tumor could provide much more informations, which not obtained by conventionalradiographic studies.

A case of hair strangulation on right toe of two months old female patient is reported together with a brief review of references in this paper. This hair strangulation was on the proximal interphanlangeal joint of the right third toe. The distal portion of the hair strangulation was discolored as black, swollon, cold and no evidence of circulation. Amputationon the metatarsophalangeal joint was done.

Ultrasonography is suited for screening patients with a mass in the soft tissue because of its safety, low cost, apparent sensitivity and non-invasiveness. But the application in orthopaedic surgery is insufficient. Authors examined 102 patients who had a palpable soft tissue mass of extremities and trunk with ultrasonography. Location, internal echogenicity, margin, and extent of soft tissue involvement, especially neurovascular bundle by tumor were evaluated. The diagnosis of mass was confirmed by histopathology after excision or biopsy of the mass. The ultrasonography correctly identified and differentiated the cystic lesions of 34 cases. The sonograms of all 16 malignant lesions showed ill-defined margin and heterogenous internal echo. The extent of soft tissue involvement, especially neurovascular bundle was confirmed exactly with ultrasonography. Therefore, in malignant tumor, after confirmation of no neurovascular involvemment with ultrasonography, limb-salvage operation could be considered and planned. In one case of abscess, percutaneous biopsy was done under guidance of ultrasonography. Therefore, ultrasonography can be used as a guide for percutaneous biopsy without exposure to radiation.

Detection and evaluation of early soft tissue changes are important in rheumatoid arthritis or other jointdiseases. The most important factors for radiologic demonstration of soft tissue changes are resolving power andthe optimization of contrast differences between structures representing skin and subcutaneous tissue densities.Phantom study was done by using combination of immersion technique and mammography to get the most reliable methodfor improvement of soft tissue contrast without deterioration of resolution. Clinical application was also done in5 normal volunteers and 5 rheumatoid patients. The results indicate that soft tissue contrast, especially betwenskin and subcutaneous tissues can be significantly imporved with combination of immersion technique andmammography with 50% ethanol in both phantom and clinical study.
