[Milwaukee shoulder syndrome: A painful swollen shoulder as a result of a rare condition].

Background: A painful and swollen shoulder has an extensive differential diagnosis, with Milwaukee shoulder syndrome (MSS) being diagnosed infrequently. Analysis of crystals in the synovial fluid is an important diagnostic step in patients with a swollen shoulder.

Case Description: A 69-year-old female presented at the orthopaedic outpatient clinic with pain, limited mobility and swelling of the left shoulder.

MRI Assessment of Muscle Damage After the Posterolateral Versus Direct Anterior Approach for THA (Polada Trial). A Randomized Controlled Trial.

Background: There is controversy in literature whether the direct anterior approach (DAA) results in less muscle damage compared with the posterolateral approach (PLA) for total hip arthroplasty. The aim of this randomized controlled trial was to assess muscle damage between these two approaches.

Methods: Forty-six patients were included.

Flow cytometric assessment of leukocyte kinetics for the monitoring of tissue damage.

Leukocyte populations quickly respond to tissue damage, but most leukocyte kinetic studies are not based on multiparameter flow cytometry. We systematically investigated several blood leukocyte populations after controlled tissue damage. 48 patients were assigned to either an anterior or posterolateral total hip arthroplasty.

Posterolateral vs Direct Anterior Approach in Total Hip Arthroplasty (POLADA Trial): A Randomized Controlled Trial to Assess Differences in Serum Markers.

Background: The direct anterior approach (DAA) for total hip arthroplasty has claimed to be a true tissue-sparing minimally invasive approach that has less tissue damage and a faster recovery when compared to the posterolateral approach (PLA). The aim of this randomized controlled trial is to measure the differences in serum markers and functional outcomes between the DAA and PLA for total hip arthroplasty.

Methods: Forty-six patients were prospectively included and randomized for either the DAA (n = 23) or PLA (n = 23).

Biomechanical evaluation of the vertebral jack tool and the inflatable bone tamp for reduction of osteoporotic spine fractures.

Study Design: Controlled in vitro study.

Objective: To compare two kyphoplasty techniques in cadaveric fractured vertebrae: an experimental vertebral jack tool (VJT) and an inflatable bone tamp (IBT).

Summary Of Background Data: A previous biomechanical study showed restored strength and stiffness after height restoration in cadaveric-fractured osteoporotic vertebrae using a new device for reduction of osteoporotic vertebral fractures.

No superiority of cemented metal-on-metal vs metal-on-polyethylene THA at 5-year follow-up.

A randomized controlled trial was performed to compare the cemented Stanmore metal-on-metal (Biomet, Warsaw, Indiana) total hip arthroplasty (THA; 102 hips) to the cemented Stanmore metal-on-polyethylene (Biomet) THA (98 hips). The primary outcome was clinical performance. Radiological performance, serum cobalt analysis, and prosthetic survival were secondary outcome measures.

Percutaneous vertebroplasty as a treatment for osteoporotic vertebral compression fractures: a systematic review.

Percutaneous vertebroplasty has been performed for more than ten years to treat painful osteoporotic vertebral compression fractures. Clinical results have been encouraging, but little is known about the efficacy and safety of this minimally invasive procedure. We therefore performed a systematic review to assess the efficacy and safety of percutaneous vertebroplasty in osteoporotic vertebral compression fractures.
