Similar radiological results with accelerometer-based navigation versus conventional technique in total knee arthroplasty.

Background: The Zimmer iASSIST system is an accelerometer-based, portable navigation device for total knee arthroplasty (TKA) that does not require the use of a large console for alignment feedback as required in computer-assisted surgery. The purpose of this study was to determine the accuracy of the accelerometer-based system in component positioning and overall mechanical alignment.

Methods: Two groups of 30 patients each with primary osteoarthritis underwent TKA using either conventional method or Zimmer iASSIST navigation in 2013 was retrospectively studied.

Patients with knee osteoarthritis demonstrate improved gait pattern and reduced pain following a non-invasive biomechanical therapy: a prospective multi-centre study on Singaporean population.

Background: Previous studies have shown the effect of a unique therapy with a non-invasive biomechanical foot-worn device (AposTherapy) on Caucasian western population suffering from knee osteoarthritis. The purpose of the current study was to evaluate the effect of this therapy on the level of symptoms and gait patterns in a multi-ethnic Singaporean population suffering from knee osteoarthritis.

Methods: Fifty-eight patients with bilateral medial compartment knee osteoarthritis participated in the study.

The minimum 10-year results of a second-generation cementless acetabular shell with a polished inner surface.

The purpose of this prospective study was to evaluate the minimum 10-year outcomes and survivorship of the Reflection shell with a polished inner surface and an improved locking mechanism. Three hundred sixty-three total hip replacements with a mean follow-up of 11.6 years (range, 10.

The relationship of the lateral cord of the brachial plexus to the coracoid process during arthroscopic coracoid surgery: a dynamic cadaveric study.

Background: Arthroscopic coracoid decompression is performed for coracoid impingement and has also been advocated for arthroscopic repair of tears of the subscapularis tendon, placing the lateral cord or the musculocutaneous nerve at risk of injury. The dynamic relationship of the lateral cord to the coracoid while the upper limb is in abduction and traction in the shoulder arthroscopy position is not clear.

Purpose: The purpose of this study was to evaluate the dynamic relationship of the lateral cord of the brachial plexus to the coracoid process during varying degrees of upper limb abduction in traction.

Vesico-hip fistula from bladder puncture with subsequent infected total hip arthroplasty.

The association of total hip arthroplasty and bladder injury has been well documented. Most cases of fistula formation between the bladder and the hip arthroplasty have occurred, either at the time of hip arthroplasty or subsequently. We report on this rare case where a bladder puncture resulted in infection of the arthroplasty.

Laparoscopic nephrectomy: new standard of care?

Objective: The pace of implementation of a laparoscopic nephrectomy programme is affected by factors including surgical expertise, case load, learning curves and outcome audits. We report our experience in introducing a laparoscopic nephrectomy programme over a 3-year period.

Methods: From January 2001 to December 2003, 187 nephrectomies were performed (105 by conventional surgery, 82 by laparoscopy).
