INTRODUCTION Olecranon fractures are common in the elderly. Articular impaction is encountered occasionally, but the incidence and outcomes after treatment of this injury pattern have not been well characterized. METHODS We evaluated a cohort of geriatric olecranon fractures to determine the incidence of articular impaction and describe a technique for open reduction and internal fixation. RESULTS Of the 63 patients in our series, 31 had associated intraarticular impaction (49.2%). Patients with articular impaction did not have significantly different rates of postoperative complications (11/31, 35.5% versus 10/31, 32.3%; P = 1.00) or revision surgery (10/31, 32.3% versus 8/31, 25.8%; P = 0.780) compared with those without articular impaction. CONCLUSION Articular impaction is a common feature of geriatric olecranon fractures. Surgeons must maintain a high index of suspicion and have a surgical plan in place for managing this component of the injury.

The lag screw or helical blade of a cephalomedullary nail facilitates controlled collapse of intertrochanteric proximal femur fractures. However, excessive collapse results in decreased hip offset and symptomatic lateral implants. Countersinking the screw or helical blade past the lateral cortex may minimize subsequent prominence, but some surgeons are concerned that this will prevent collapse and result in failure through cutout. We hypothesized that patients with countersunk lag screws or helical blades do not experience higher rates of screw or blade cutout and have less implant prominence after fracture healing.A retrospective review of 175 consecutive patients treated with cephalomedullary nails for AO/OTA 31A1-3 proximal femur fractures and a minimum 3-month follow-up and 254 patients with a 6-week follow-up at a single US level I trauma center. Patients were stratified based on countersunk versus noncountersunk lag screw or helical blade in a cephalomedullary nail. The primary outcome was the cutout rate at minimum 3 months, and the secondary outcome was radiographic collapse at minimum 6 weeks.Cutout rates were no different in patients with countersunk and noncountersunk screws and blades, and countersinking was associated with less collapse and less implant prominence at 6 weeks.Surgeons can countersink the lag screw or blade when treating intertrochanteric proximal femur fractures with a cephalomedullary nail without increasing failure rates and with the potential benefits of less prominent lateral implants and decreased collapse.

To determine whether drilling energy correlates with bone mineral density (BMD), maximum insertion torque (MIT), maximum screw compression, and pullout strength (POS).Ten cadaver tibias were used for testing. Unicortical pilot holes were drilled and the drilling energy measured. Drill site bone quality was determined with microcomputed tomography. Drill holes were randomly assigned to POS or MIT testing using 3.5-mm cortical screws engaging only the near cortex. Pearson correlation coefficients were calculated to determine the relationship between drilling energy, BMD, POS, MIT, and maximum screw compression.Drilling energy was correlated with BMD (P0.001). Compared with BMD, drilling energy had a better correlation with MIT, maximum screw compression, and POS. Maximum screw compression also correlated with MIT (P = 0.012).Drilling energy better correlates with MIT, maximum screw compression, and POS compared with BMD in cadaver cortical bone. Dynamically measuring drilling energy may help inform the orthopaedic surgeon as to the quality of the bone before insertion of implants.
