1.Perinatal Hypoxic-lschemic Brain Injury: MR Findings.
Journal of the Korean Radiological Society 1994;31(3):405-410
PURPOSE: To characterize the MR findings of hypoxic-ischemic brain injury and to assess the value of the MR imaging. MATERIALS AND METHODS: SE T1 -, T2-weighted, and IR brain MR images of 44 infants and children with the past history of perinatal hypoxic insults were reviewed. Abnormal brain MR findings of 8 patients with birth history of prematurity and 36 patients with birth history of full-term/posterm including 7 with severe anoxic insult history, were compared in regard to the location and the character of the lesions RESULTS: MRI demonstrated the followings;(1)abnormal signal intensity lesions of subcortical and/or deep cerebral white matter, cortex, and deep gray matter, (2)atrophy of the cerebral white matter, cortex and corpus callosum, with/without ventriculomegaly, and (3)delay in myelination. Periventricular and deep white matter lesions were demonstrated in the prematurity, the deep white matter lesions and/or subcortical white matter lesions in the term/post-term, and deep gray matter lesions in the 7 patients with severe anoxic insults history. CONCLUSION: MR imaging was useful in the diagnosis of the hypoxic-ischemic brain injury, and the white and gray matter lesions were correlated with the time of the injury and the severity of hypoxic insult.

BACKGROUND: The goal of this study was to evaluate whether a modified fluoroscopic technique for positioning a hook plate affected the clinical results of treating Neer type II distal clavicle fractures and Rockwood type V acromioclavicular (AC) joint separations with this device. METHODS: The study was a retrospective consecutive case series with data analysis. Sixty-four patients with a Neer type II distal clavicle fracture or a Rockwood type V AC joint injury treated between March 2009 and June 2013 were divided into 2 groups: traditional fluoroscopic technique (traditional view, 31 patients) or modified fluoroscopic technique ('hook' view, 33 patients). A visual analogue scale (VAS) score, the modified University of California-Los Angeles (UCLA) shoulder scale score, and radiographic osteolysis were the main outcome measures. RESULTS: The traditional group included a significantly larger number of patients with acromial osteolysis than the hook view group: 23 patients (74.2%) vs. 11 patients (33.3%), respectively (p=0.01). Before plate removal, the hook group reported less pain and higher UCLA shoulder scale scores than the traditional group: average VAS score, 1.55 vs. 2.26, respectively; average UCLA score, 30.88 vs. 27.06, respectively. However, there was no significant difference after plate removal. CONCLUSIONS: The hook view allows more accurate bending of the hook plate around the contour of the acromion, resulting in decreased osteolysis, decreased pain, and better function with the plate in situ.

BACKGROUND: For the purpose of early detection of breast cancer, a localization biopsy is necessary in case of mammographically or ultrasonographically suspicious, but nonpalpable, breast lesions. METHODS: One hundred nine consecutive localization biopsies for nonpalpable lesions of the breast were performed upon 101 patients from May 1992 to September 1998. RESULTS: The localizations were done in 48 cases under the guidance of mammography and in 61 cases under the guidance of ultrasonography. Complications occurred in 15 cases (13.7%). The mean volume of the excised specimens was 11.6 cm3. The miss rate was 3.6% (4 cases). Malignant lesions of the breast were found in 16 cases (14.7%). Among the malignant lesions, 10 cases involved invasive ductal cancer. Among the patients diagnosed as having breast cancer, 8 patients were treated with a conservative operation, 5 patients with a modified radical mastectomy, and 2 patients with observation; 1 patient was discharged. The chance of a biopsy containing a malignant lesion was 16.7% if the biopsy was done because of mass, 9.8% for a microcalcification, and 11.1% for an abnormal asymmetric density. CONCLUSIONS: A needle localization biopsy can be performed accurately under local anethesia, and the volume of the excised specimen can be minimized, so the cosmetic effect is excellent and proper early treatment is possible in diagnosed cases of breast cancer.

Injuries to the extensor mechanism include a wide range of injuries from minor one to massive defect. And the methods of treatment must be individualized according to the anatomical site, extent and chronicity of injuries. The extensor mechanism is a triangular thin sheet like structure, the function of which cannot be explained completely by the Tubiana's church-steeple like diagram. Authors think that the extensor mechanism should be repaired or reconstructed as a triangular sheet. The tension of the repaired or reconstructed tendon was estimated as good when the neutral extensions were obtained in all the MP, PIP and DIP joints after the completion of sutures. Also authors think that stable sutures are mandatory for the early rehabilitation postopoeratively. Seventy-five patients have been treated by the authors from 1982 to 1994. According to zonal classification, forty-two patients were injured in Zone I. 5 in Zone II, 21 in Zone III, 5 in Zone IV and 2 patients were unclassified due to massive defects of the extensor mechanism. Mostly bony mallet injuries were treated by open reduction and K-wire fixation. Acute tendinous mallet injuries were treated by conservative splinting and old injuries were treated by anatomical plication of the terminal extensor tendon. Old buttonhole deformities were generally treated by the central tendon plication. Massive defects were managed by skin coverage and reconstruction of the extensor mechanism by using a tendon graft which was tailored like a triangular thin sheet. With author's treatment principles, excellent or good results were obtained in about 87%. Consequently, authors emphasize that an anatomical repair or reconstruction is a keystone in the treatment of injuries to the extensor mechanism.

Periprosthetic humeral fractures in patients with total shoulder arthroplasty are rare and difficult to treat. With the significant increase in the number of older patients who have undergone total shoulder arthroplasty in recent years, an increase in the number of periprosthetic shoulder fractures can be estimated. The decisions of treatment have to be taken individually, depending on the stability of the prosthesis, fracture location, and bone quality. On the other hand, there are limited data for treatment guidance and outcomes. This paper reviews the risk factors, classification, treatment, and outcomes of periprosthetic humeral fractures.
