BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

We report a case of fibrous hamartoma of infancy in a 7-month-old male infant, in which a solitary, asymptomatic, walnut-sized, nomal skin-colored plaque occurred on the left middle back for about one month. Histopathologic findings showed the distinctive features of fibrous hamartoma of infancy, ie, trabeculae of dense collagenous tissue, whorls of immature spindle cells within a mucoid matrix, and interspersed mature adipose tissue, in the lower dermis. The lesion was excised without recurrence.

We herein report a case of keratoderma showing the combined clinical manifestations of striate and marginal keratoderma. The patient was a 18-year-old giri who about a year ago noticed slightly yellowish, well-circurnscribed, hyperkeratotic plaques on the volar aspect of the fingers and palms of both hands in a linear pattern with bands of hyperkeratotic plaques at the edeges of the 2nd fingers. We also found hyperkeratotic plaques on the both soles which were confined to sites of pressure. She denied a history of any chronic pressure or trauma. There was no family member showing the same clinical features. The histopathological findings from the palm, volsr aspect of finger and a sole revealed marked hyperkeratosis, hypergranulosis, and acanthosis.

BACKGROUND: To evaluate the effect of preoperative fatty degeneration of deltoid and teres minor muscles on the clinical outcome in patient with reverse total shoulder arthroplasty (RTSA). METHODS: Nineteen patients with RTSA were enrolled. The mean follow-up period was 16.1 months. The fatty degeneration of three distinct parts in each deltoid and the teres minor muscle was measured using a preoperative magnetic resonance imaging. Postoperatively, the muscle strengths for forward elevation (FE), abduction (Abd), and external rotation (ER) were measured using a myometer at the last follow-up. The parameters for clinical outcome were Constant Score (CS) and Korean Shoulder Score (KSS). RESULTS: The number of cases was 10 in group 1 and 9 in group 2. The strength of FE and Abd were significantly higher in group 1 (p<0.001 and p<0.001, respectively), and the strength of ER was not different significantly between two groups (p=0.065). For the clinical outcome, both CS and KSS were higher in group 1 (p=0.002 and p=0.002, respectively). The number of patients in group A was 11, and group B was 8. Although there was not a significant difference in terms of FE and Abd between group A and B (p=0.091, p=0.238), ER was significantly higher in group A (p=0.012). We did not find a significant difference in the clinical scores (CS, p=0.177 and KSS, p=0.238). CONCLUSIONS: These findings suggest the importance of a preoperative evaluation of the fatty degeneration of deltoid and teres minor muscles for predicting postoperative strength and clinical outcome.

PURPOSE: To measure the size of normal corpus callosum in each portion using objective and reproducible method with MRI and evaluation of morphological change of corpus callosum by grade of hydrocephalus. MATERIALS AND METHODS: Midsagittal Tl-weighted MR imaging of the corpus callosum was investigated in 41 volunteers of normal Korean adults and 19 patients with hydrocephalus. Corpus callosum was measured for the anteroposterior length(A), height(B), and the thickness of genu(C), body (D), splenium(E), and the narrowest portion of body(F). And the analysis of morphology and signal intensity of the corpus callosum were also evaluated. Hydrocephalus was graded as mild, moderate, and severe, and comparision of thickness with normal corpus callosum in each portion was done. RESULTS: The mean length and height were 72.3mm, 28.6mm in male, and 70.7ram, 28.9mm in female. And the mean dimention for C, D, E, and F were 13.1 ram, 8ram, 13.2mm, 5.2ram in male, and 12.8mm, 7.5ram, 12.3 ram, 5mm in female. The morphology of normal corpus callosum was "hook" shaped on midline sagittal Tl-weighted image. Narrowing at posterior third portion of body were present on 30 cases(73.2%) and even in thickness of the body in 11 cases(26.8%). The signal intensity of the corpus callosum on midsagittal Tl-weighted spin echo image of normal cases was homogeneous hyperintense as compared with cerebral gray matter. In hydrocephalus, A and B were increased and other portions were decreased in thickhess. Genu and the narrowest portion of body showed significant difference of thickness according to the grade of hydrocephalus. CONCLUSION: The mean dimention of all portion of corpus callosum were larger in male than female except for callosal height but not significant statistically with the exception of splenium. Hydrocephalus lead to morphological change of the corpus callosum. Among the portion of corpus callosum, genu and the narrowest portion of the body were thought to be the most sensitive indicators of degree in hydrocephalus.
