BACKGROUND: The purpose of this study was to determine whether currently published outcome measures of physical function would be suitable for use for older adults with a hip fracture. The measures that were considered were the Musculoskeletal Function Assessment (MFA) Instrument, the Older Americans' Resources and Services (OARS) Multidimensional Functional Assessment Questionnaire physical function subscale, the Toronto Extremity Salvage Score (TESS), and the Short Form-36 (SF-36). ...

Our purpose was to study the relationship between the number of plate holes filled and the spacing between the screws and the resultant strength of plated constructs. Broad regular DC plates were anchored with 4.5-mm cortical screws to blocks of polyurethane foam. Six constructs were tested: (a) screws in holes 1, 2, and 3; (b) screws in holes 1 and 3; (c) screws in holes 1 and 4; (d) screws in holes 1 and 5; (e) screws in holes 1 and 6; (f) screws in holes 1, 3, and 5. The strength was ...

OBJECTIVE: To examine predictors of fixation failure in the treatment of displaced subcapital hip fractures.

DESIGN: Retrospective study.

METHODS: All patients aged sixty-five years and older discharged from a large teaching hospital after treatment for displaced subcapital fracture between April 1, 1989 and February 29, 1995 were identified (n = 344). Of these, 108 patients treated with internal fixation became the study group. Clinical information included demographics, implant, ...

We believe that there is no place for nonoperative treatment of the subtrochanteric fracture. In our approach to this fracture we greatly advocate the AO/ASIF principles of accurate anatomic reduction and stable internal fixation. We make use of this in our practice and prefer to treat subtrochanteric fractures in this manner when this is applicable and possible. However, the elderly patient with gross comminution with considerable osteoporosis presents a formidable problem requiring a ...

The purpose of this study was to determine whether the alterations in the relative dimensions of thread and core diameter that accompany cannulation of cancellous bone screws affect their holding strength. The screws were inserted in bovine femoral cancellous bone and mounted in the load train of a materials testing system. They were then extracted under servo-hydraulic displacement control. The tests were repeated in synthetic cancellous material. From the corresponding ...

The purpose of the study was to determine whether tapping affects the holding strength of cancellous bone screws in soft material. Paired extraction tests were conducted using 6.5 mm cancellous bone screws in porous polyurethane foam. One member of each pair had a pre-tapped pilot hole, the other was inserted in a self-tapping manner. The maximum value of tensile force during extraction with a servohydraulic materials testing machine was recorded as the screw ...
