Background: The purpose of this study was to evaluate the clinical and radiological results after arthroscopically assisted image intensifier–controlled stabilization high-grade acromioclavicular (AC) joint separations using double TightRope technique with first-generation implant. Hypothesis: implant leads good by re-creating anatomy AC joint. Study Design: Case series; Level evidence, 4. Methods: Thirty-seven consecutive patients (4 women 33 men; mean age, 38.6 years) who sustained an...

Background: Arthroscopic double-row fixation of supraspinatus tendon tears compared with single-row techniques is still a matter debate. Hypothesis: rotator cuff repair using the suture bridge technique provides better clinical results and lower retear rates than does modified Mason-Allen stitch technique. Study Design: Cohort study; Level evidence 3. Methods: Forty patients underwent either an arthroscopic (SR) (n = 20; mean age ± SD, 61.5 7.4 y) or (DR) age, 61.2 7.5 y). The...

The incidence of rotator cuff tears and recurrent defects positively correlate with patient age. However, this observation has never been analysed at the cellular level. present study aims to better understand correlation by investigating characteristics tenocytes different age groups. Additionally, previous studies reported on stimulating effects Bone Morphogenetic Protein (BMP) -2 BMP-7 tenocytes. Thus, second aim was investigate, whether stimulation potential demonstrates age-related...

Arthroscopic rotator cuff repair (RCR) with suture anchor-based fixation techniques has replaced former open and mini-open approaches. Nevertheless, long-term studies are scarce, lack of knowledge exists about whether single-row (SR) or double-row (DR) methods superior in clinical anatomic results.To analyze results after arthroscopic RCR patients symptomatic tears to compare functional radiographic outcomes between SR DR at least 10 years surgery.Cohort study; Level evidence, 3.Between 2005...

Patients with posterosuperior cuff tears lose functional external rotation of the shoulder. Latissimus dorsi and teres major transfer is performed to restore rotation. Twenty patients a mean age was 55.8 +/- 6 years underwent this procedure were examined at averages 24.7 (n = 17) 70.6 13) months. Two did not improve presumably because failure transfer. The Constant Murley score increased from 55.6 90.4 after 2 87.9 5 years. active flexion 119.4 degrees 169.3 reached 170 years, 12 35 ,...

Osteoporosis and associated fractures are a major public health burden there is great need for large animal model. Melatonin, the hormone of pineal gland, has been shown to influence bone metabolism. This study aims evaluate whether absence melatonin due pinealectomy affects mass, structure remodeling in an ovine model.Female sheep were arranged into four groups: Control, surgically ovariectomized (Ovx), pinealectomized (Px) Ovx+Px. Before 6 months after surgery, iliac crest biopsies...

Abstract Background Reverse shoulder arthroplasty (RSA) is a common treatment for proximal humeral fractures. (PHF) in the elderly. This study evaluates functional outcome and influence of. tuberosity healing (TH) following RSA with 135° inclination neutral glenosphere without lateralization PHFs. Methods In this retrospective case series, all patients an acute PHF treated primary standard during four-year period were followed up. Constant score (CS), patient satisfaction (subjective value...

Abstract Objective Functional posterior shoulder instability (FPSI) (type B1) is a severe type of instability, mainly in teenagers and young adults, that leads to loss function, pain, stigmatization among peers. An experimental nonsurgical treatment protocol based on neuromuscular electrical stimulation (NMES) showed very promising early results the FPSI. The hypothesis this study was NMES-enhanced physical therapy better outcomes than alone as current gold standard patients with Methods In...

Tendon bone healing of the rotator cuff is often associated with non-healing or recurrent defects, which seems to be influenced by patient's age and sex. The present study aims examine cellular biological characteristics tenocyte-like cells that may contribute this impaired healing. Moreover, a therapeutic approach using growth factors could possibly stimulate tendon Therefore, our second aim was identify patient groups who would particularly benefit from factor stimulation. Tenocyte-like...
