Young patients with hip fracture: a population-based study of bone mass and risk factors for osteoporosis.

Introduction: Hip fracture in young patients is rare. The present study was aimed to clarify the comorbidity pattern and reveal relevant risk factors for osteoporosis and fracture in this patient group.

Materials And Methods: Using electronic diagnosis registers and lists of the operating theatres for the Oslo hospitals, patients with new hip fracture during two 1-year periods from May 1994 through April 1995 and from May 1996 through April 1997 were identified.

Local and national electronic databases in Norway demonstrate a varying degree of validity.

Objective: The aim of the present study was to examine the validity of local and national electronic databases using medical records as gold Standard.

Study Design And Setting: All hospital admissions with ICD 9-code 820.X (hip fracture) in a 1-year period were identified in the electronic discharge registers of the hospitals in Oslo and in the national electronic database (The Norwegian Patient Register).

Consequences of hip fracture on activities of daily life and residential needs.

The aim of this study was to describe the consequences of hip fracture with respect to changes in residential needs and the ability to perform activities of daily life. Patients 50 years and older admitted to the two largest hospitals of Oslo with a hip fracture during the period May 1996 through April 1997 were identified. In November 1997 a questionnaire on residential needs, activities of daily life, hip pain and health status was sent to the patients still alive (n = 767).

Epidemiology of hip fractures in Oslo, Norway.

The incidence of hip fractures in Oslo has shown a secular increase during the past decades. The main aims of the present study were to report the current incidence of hip fractures in Oslo and to determine whether there is a seasonal variation in the occurrence of fractures. Using the electronic diagnosis registers and the lists of the operating theater for the hospitals in Oslo with somatic care, all patients with ICD-9 code 820.

More postoperative femoral fractures with the Gamma nail than the sliding screw plate in the treatment of trochanteric fractures.

Despite several studies showing a higher incidence of peri-implant femoral fractures with the Gamma nail than with a sliding screw plate (SSP), the Gamma nail has remained the standard implant for trochanteric fractures in many hospitals. We recorded 921 trochanteric fractures in the city of Oslo during 2 years and compared the reoperation frequency in patients treated with the Gamma nail (n 379) and SSP (n 542). The distribution of age and gender in the two treatment groups was the same.
