Long-Term Results of Primary Reverse Shoulder Arthroplasty for Massive, Irreparable Rotator Cuff Tears Without Glenohumeral Arthritis with a Mean Follow up of 9.4 Years.

Background: The aim of this single-center study was to analyze the long-term clinical results of reverse shoulder arthroplasty in patients with massive, irreparable rotator cuff tears without glenohumeral arthritis.

Methods: A retrospective cohort study of 105 patients (115 shoulders) was conducted. The mean age of the patient group was 76 years (range, 65 to 87 years).

Results of reconstruction of massive irreparable rotator cuff tears using a fascia lata allograft.

Background: Despite the advances in surgical treatment options, massive rotator cuff (r-c) tears still represent a challenge for orthopedic surgeons. This study assesses the effectiveness of fascia lata allograft in reconstruction of massive and irreparable r-c tear and to evaluate the healing and functional outcomes.

Materials And Methods: 68 patients (38 men, 30 women, mean age 64.

Fascia lata allograft bridging of a rotator cuff tear in a rabbit animal model.

Purpose: Despite advances in surgical treatment options, large rotator cuff (r-c) tears still represent a challenge for orthopedic surgeons. The purpose of this study was to evaluate the temporary and spatial histological incorporation of fascia lata allografts, used for bridging artificially created defects of the r-c.

Materials And Methods: Seventy-two rabbits were divided into two groups and a supraspinatus tendinous defect was created.

Ochronotic arthropathy: diagnosis and management: a critical review.

Alkaptonuria, a rare hereditary metabolic disorder, is characterized by accumulation of homogentisic acid in the connective tissues resulting from lack of the enzyme homogentisic acid oxidase. Ochronosis, dark pigmentation of connective tissues, is the musculoskeletal manifestation of alkaptonuria. In this article, we report the case of a 53-year-old man who had ochronotic arthropathy and advanced degenerative changes in the shoulders managed with bilateral total shoulder arthroplasty.

The effect of local use of nandrolone decanoate on rotator cuff repair in rabbits.

Objective: There is still controversy about the effect of anabolic steroid on connective tissue. This study examines the hypothesis that the local use of nandrolone decanoate, an anabolic steroid on rotator cuff, facilitates the healing process when used in combination with surgical repair.

Methods: Forty-eight male rabbits were divided in four groups with anabolic steroids (Nandrolone Decanoate 10 mg/kg) and immobilization as variables.
