Recent reports using the Mangled Extremity Severity Score (MESS) suggest that a score of > or = 7 is 100% accurate in predicting the need for amputation of severely injured lower extremities. To further evaluate the value of the MESS in predicting amputation, specifically with respect to type IIIB and type IIIC (Gustilo and Anderson) open fractures of the tibia, we retrospectively evaluated 24 patients with these injuries. A significant difference (p = 0.001) between MESS values of 13 salvaged (6.36 +/- 0.35 SEM) and 11 amputated limbs (6.36 +/- 0.54 SEM) was found. ⋯ We modified the MESS with a score called the NISSSA and applied it retrospectively to our cases. After careful statistical comparison we found both the MESS and NISSSA to be highly accurate (p < 0.005) in predicting amputation. The NISSSA was found to be more sensitive (81.8% versus 63.6%) and more specific (92.3 versus 69.2%).

The current literature tends to favor rigid internal fixation with plates for symptomatic midclavicular nonunions. From 1985 to 1992, 14 patients with clavicular nonunions were treated by open reduction and intramedullary Steinman pin fixation with onlay iliac crest bone grafting. The average age of patients was 36 years (range 18-62). ⋯ The most significant complications were two refractures occurring through osteopenic bone. We have found this technique to be as effective as plating procedures, yet it maintains the great advantage of ease of hardware removal. It allows early motion and has been useful in those whose previous plating procedures have failed.
