Epidemiology and changed surgical treatment methods for fractures of the distal radius: a registry analysis of 42,583 patients in Stockholm County, Sweden, 2004–2010.

Background And Purpose: The incidence of fractures of the distal radius may have changed over the last decade, and operative treatment has been commoner during that time. We investigated the incidence of fractures of the distal radius and changing trends in surgical treatment during the period 2004-2010.

Patients And Methods: Registry data on 42,583 patients with a fracture of the distal radius from 2004 to 2010 were evaluated regarding diagnosis, age, sex, and surgical treatment.

The effect of weekly risedronate on periprosthetic bone resorption following total hip arthroplasty: a randomized, double-blind, placebo-controlled trial.

Background: Bone loss leading to late-occurring periprosthetic femoral fracture is a mode of failure in cementless total hip arthroplasty. The aim of this trial was to investigate the effect of a bisphosphonate, risedronate, on femoral periprosthetic bone resorption following total hip arthroplasty in patients with osteoarthritis of the hip.

Methods: We enrolled seventy-three patients between the ages of forty and seventy years who were scheduled to undergo total hip arthroplasty in a single-center, randomized, double-blind, placebo-controlled trial.

Wrist function recovers more rapidly after volar locked plating than after external fixation but the outcomes are similar after 1 year.

Background And Purpose: Promising results have been reported after volar locked plating of unstable dorsally displaced distal radius fractures. We investigated whether volar locked plating results in better patient-perceived, objective functional and radiographic outcomes compared to the less invasive external fixation.

Patients And Methods: 63 patients under 70 years of age, with an unstable extra-articular or non-comminuted intra-articular dorsally displaced distal radius fracture, were randomized to volar locked plating (n = 33) or bridging external fixation.

Evaluation of a Swedish version of the patient-rated wrist evaluation outcome questionnaire: good responsiveness, validity, and reliability, in 99 patients recovering from a fracture of the distal radius.

The patient-rated wrist evaluation (PRWE) form is an established outcome questionnaire designed to measure wrist pain and disabilities in activities of daily living. We translated and validated this score for use in Sweden. The original PRWE score was translated forwards and backwards, and then the responsiveness, validity, and reliability of the Swedish version were tested in 99 patients who were recovering from a fracture of the distal radius.

Large femoral bone loss after hip revision using the uncemented proximally porous-coated Bi-Metric prosthesis: 22 hips followed for a mean of 6 years.

Background And Purpose: Periprosthetic bone loss after uncemented femoral hip revision is a matter of concern. We have used a proximally porous- and hydroxyapatite-coated prosthesis (Bi-Metric) in revision since 1989 and now we report the bone changes. This prosthesis is intended to distribute the forces more evenly and to avoid proximal femoral unloading.

Good results with an uncemented proximally HA-coated stem in hip revision surgery: 62 hips followed for 2-13 years.

Background And Purpose: Proximal bone loss due to stress-shielding is a matter of concern after uncemented femoral hip revision. We have used short, proximally hydroxyapatite-coated prostheses in revision since 1989, and we now report the results.

Methods: 60 patients (62 hips) were revised because of aseptic loosening.

Medium-term results after primary hemiarthroplasty for comminute proximal humerus fractures: a study of 46 patients followed up for an average of 4.4 years.

This study investigated 82 patients who underwent primary hemiarthroplasty for a severely displaced proximal humerus fracture at Danderyd Hospital between 1989 and 2002. According to the Neer classification system, fractures were 2-part in 2, 3-part in 20, and 4-part in 60. The prostheses used were 12 Neer-II, 39 Global, and 31 Bigliani-Flatow.

Patient-perceived outcome after displaced distal radius fractures. A comparison between radiological parameters, objective physical variables, and the DASH score.

Outcome after distal radius fractures has traditionally been measured by radiological parameters and objective physical variables. To what extent these measurements reflect outcome as perceived by the patient has been questioned. We evaluated the association between radiological position, objective physical result (grip strength and range of movement), and the patient-perceived outcome, measured with the Disabilities of the Arm, Shoulder, and Hand outcome (DASH) score, in 78 patients with a healed unilateral distal radius fracture treated with either closed reduction and plaster splint or external fixation.

Continuous bone loss around a tapered uncemented femoral stem: a long-term evaluation with DEXA.

Background: Periprosthetic bone loss is a well-documented phenomenon after uncemented total hip arthroplasty (THA); however, little is known about how bone mineral density (BMD) changes after 2 years.

Patients And Methods: 14 patients with hip arthrosis (group A) were operated with a proximally porous- and hydroxyapatite-coated stem and followed for 10 years with DEXA, radiographs and Harris hip score (HHS). Another group of 14 patients (group B) was evaluated at 6 and 14 years using the same prosthesis and protocol.

Periprosthetic proximal bone loss after uncemented hip arthroplasty is related to stem size: DXA measurements in 138 patients followed for 2-7 years.

Background: Periprosthetic bone loss occurs around uncemented femoral stems and may be influenced by the stem size.

Patients And Methods: We studied 138 consecutive patients, 3 (2-7) years on average after a total hip arthroplasty operation (THA) for unilateral osteoarthritis with the Bi-Metric uncemented femoral stem. We analyzed Harris hip score and bone mineral density.
