The patellar pubic percussion test: a simple bedside tool for suspected occult hip fractures.

Purpose: Patellar finger tapping produces a typical sound that can be detected by a stethoscope positioned on the pubic bone (patellar pubic percussion test (PPPT)). Characteristics of this sound are determined by continuity of bone between patella and pelvis. We hypothesized that a PPPT was able to detect overt hip fractures and occult hip fractures that may not be determined by a standard radiological examination.

Z-effect after intramedullary nailing systems for trochanteric femur fractures.

Purpose: The aim of this study was to investigate the incidence of Z-effect after dual lag screw intramedullary nailing systems and risk factors contributing to this effect. We hypothesized that long nails provide more neck strength due to a longer lever than short nails and are therefore less likely to develop a misbalance of a higher head compressive strength than neck compressive strength.

Methods: In this retrospective cohort study 103 patients treated operatively with a dual lag screw intramedullary nailing device for (sub)trochanteric hip fracture were included.

A head to head comparison of nine tools predicting non-sentinel lymph node status in sentinel node positive breast cancer women.

Background And Objectives: This study was conducted to evaluate the performance of available tools predicting non-sentinel lymph node (non-SLN) status in women with SLN positive breast cancer and to see if they can be safely used in everyday clinical practice.

Methods: Data of 220 women with breast cancer who underwent a SLN biopsy at the Máxima Medical Centre between 2000-2008 were analysed. Tools evaluated were: the models from Memorial Sloan Kettering Cancer Centre, Stanford, Mayo, Cambridge, Gur, and MOU, and the scores from Saidi, Tenon, and MDA.

[Treatment of injuries of the Chopart joint].

Background: Injuries to the Chopart joint of the tarsal foot are relatively rare, difficult to recognize and are associated with significant long term morbidity.

Case Description: A 16-year-old boy attended the emergency department after a forklift truck ran over his left foot. Physical examination and X-ray evaluation revealed a fracture of the Chopart joint with a navicular bone fracture and dislocation of the calcaneo-cuboidal joint.

Long-term follow-up of axillary recurrences after negative sentinel lymph node biopsy: effect on prognosis and survival.

As axillary recurrence (AR) after a negative sentinel lymph node biopsy (SLNB) is rare, the prognosis of these patients is unknown. Since treatment paradigms for patients with breast cancer are shifting toward less axillary surgery, the number of ARs might increase. In this study, we evaluated primary and salvage treatment as well as long-term survival of patients diagnosed with an AR.
