Transverse tears of the volar skin of a finger with a hyper-extension injury is associated with frequent volar plate tears or avulsions. Recognition is essential for surgical exploration of the volar plate and supporting joint structures and, if injured, surgical repair should be carried out at the time of skin suturing.
Reduction and fixation of malar complex fractures has been emphasized and re-emphasized. Simple methods of reduction for complicated fractures are still advocated with clinically poor results. The necessity for a three point fixation and overcorrection for the complex fracture is emphasized. While it is true that simple fractures may be reduced by simple techniques, these simple methods cannot be applied to more comminuted fractures.
A study of undergraduate medical students' abilities to identify salient information in reviewing patient charts was conducted by members of the Department of Surgery at Southern Illinois University School of Medicine. Specific goals of the two-year study were to develop and test a method for assessing chart skills and to test the following hypotheses: (a) knowledge base is a component of chart review skill; (b) chart skills are related to basic observational skills; (c) performance on one chart is positively correlated with performance on other charts; (d) chart performance is affected by distraction and time pressure; and (e) chart performance improves with clinical experience. Evaluation instruments and methodology are described. Hypotheses a, b, and e and the time effect hypothesized in d were supported; hypothesis c was not supported. Results of the study provide a foundation for further research exploring the effect of instruction on chart performance and investigating the relationships between chart performance and other measures of clinical competence.

One of the most difficult areas on the body to skin graft successfully is the interscapular and upper back region. We have used a wire "basket" to immobilize the interscapular region in 8 patients following wide excision for melanoma. "Takes" amounting to more than 90% in 7 patients and 80% in 1 patient have been obtained. The technique is simple and inexpensive.
