Clinical orthopaedics and related research
-
The use of smartphones and their associated applications (apps) provides new opportunities for physicians, and specifically orthopaedic surgeons, to integrate technology into clinical practice. ⋯ The use of smartphones and apps is prevalent among orthopaedic care providers in academic centers. However, few highly ranked apps specifically related to orthopaedic surgery are available, and the types of apps available do not appear to be the categories most desired by residents and surgeons.

Comparative StudyPelvic positioning creates error in CT acetabular measurements.
CT allows for accurate measurement of acetabular orientation and shape, but malpositioning of the pelvis may lead to measurement variance. ⋯ Small changes in pelvic obliquity and tilt were associated with variances in acetabular measurements. The measured changes were directly proportional to the changes in obliquity and tilt, and were additive. Pelvic rotation created no changes in measurement.

Comparative StudyAspirin decreases heterotopic ossification after hip resurfacing.
Heterotopic ossification (HO) is a concern for patients undergoing hip surgery, especially surface replacement arthroplasty (SRA) who tend to be younger, more active, and anticipate good motion. It is unclear, however, whether HO occurs more frequently after SRA than traditional total hip arthroplasty (THA) and whether aspirin influences the risk. ⋯ The risk of HO is greater in SRA than in THA in patients treated with warfarin postoperatively; aspirin appears to decrease the incidence and severity of HO after hip resurfacing surgery to a similar level as total hip arthroplasty.

Comparative Study2010 mid-America Orthopaedic Association Physician in Training Award: healing complications are common after locked plating for distal femur fractures.
Several mechanical studies suggest locking plate constructs may inhibit callus necessary for healing of distal femur fractures. However, the rate of nonunion and factors associated with nonunion are not well established. ⋯ We found a high rate of nonunion in distal femur fractures treated with locking plates. Nonunion presented late without hardware failure and with limited callus formation suggesting callus inhibition rather than hardware failure is the primary problem. Mechanical factors may play a role in the high rate of nonunion.
