Purpose This paper aims to present a hierarchical motion planner for planning the manipulation repose long and heavy objects considering external support surfaces. Design/methodology/approach The includes task-level layer motion-level layer. formulates problem at task level by grasp poses as nodes object edges. considers regrasping constrained in-hand slip (drooping) during building graphs find...

OBJECTIVE To evaluate the functional and anatomical results from surgical treatment via arthroscopy in cases of complete rupture of the rotator cuff, using ultrasound images and the Constant and Murley functional index to investigate the correlation between them. METHODS 100 patients (110 shoulders) were evaluated. The mean follow-up was 48.8 ± 33.28 months (12 to 141 months). The mean age wa...

BACKGROUND The purpose of this study was to evaluate the functional and anatomic results of arthroscopic rotator cuff repair, and to analyze the factors affecting the integrity of arthroscopically repaired rotator cuff tears of the shoulder. METHODS One hundred sixty-nine consecutive shoulders that underwent arthroscopic rotator cuff repair, had a postoperative MRI evaluation and were followe...

We performed ninety-five consecutive Latarjet procedures for the treatment of recurrent anterior instability of the shoulder between 1969 and 1983. In 1993, we retrospectively reviewed the clinical and radiographic results that were available for fifty-six patients (fifty-eight shoulders) who had been followed for an average of 143 years (range, ten to twenty-three years). The purpose of the st...

BACKGROUND The purpose of this study was to review the survivorship, radiologic and clinical outcomes of reverse shoulder arthroplasty (RSA) used for the treatment of 3-part and 4-part proximal humeral fractures in the elderly. METHODS Between 2003 and 2009, 29 shoulders in 28 elderly patients (87% female) with a 3-part or 4-part fractures were managed with RSA in Brisbane, Australia. Clinica...
