Periprosthetic bone density changes after MiniHip cementless femoral short stem: one-year results of dual-energy X-ray absorptiometry study.

Introduction: The purpose of the current study was to investigate the reaction of the femur to the implantation of the MiniHip in terms of: (1) bone density change during one year; (2) correlations between stem length, CCD (caput-collum-diaphyseal), femoral offset, T-value, and bone density; (3) other co-variables that influence the change of bone density.

Patients And Methods: MiniHip implant was performed for 62 patients. The age range of the patients who underwent treatment was 25-78 years.

Humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer in patients with rotator cuff tear arthropathy and preserved subscapularis muscle function: preliminary report and short-term results.

Purpose: Humeral resurfacing arthroplasty represents an alternative option to hemiarthroplasty for treatment of cuff tear arthropathy (CTA), with the advantages as follows: suitability for relatively young and high-demand patients because of preservation of bone stock and no loss of length, less invasive surgery, shorter operation time, no risk of periprosthetic stem fractures, and revision surgery can be undertaken easily. In the current study, resurfacing arthroplasty in combination with latissimus dorsi tendon transfer for CTA was performed. Three hypotheses: first, humeral resurfacing arthroplasty in combination with latissimus dorsi tendon transfer would improve the overall functional outcome in patients with CTA.

Arthroscopic treatment of iliopsoas impingement (IPI) after total hip replacement.

Purpose: The purpose of the study was to present our arthroscopic surgical technique and the results in patient with an iliopsoas impingement (IPI) syndrome after a hip replacement.

Materials And Methods: Between 1999 and 2011, 35 patients with the clinical picture of an IPI after total hip replacement were diagnosed and treated arthroscopically. The age was ranged from 58 to 82 years.
