Filter by:Sayed Issa's Hybrid Shoulder Arthroscopic-Open Surgical Management (HSSM) is a limited lateral approach to the shoulder arthroscopically guided. Which achieves less surgical trauma and smaller surgical incision than even in Mini Lateral Shoulder Approach (MLSA).
Rotator cuff tear (RCT) is a commonly seen pathology in shoulder disease, which causes significant disability in daily living and work. Based on a cohort study of a large population, the prevalence of rotator cuff full-thickness tear was 20.7%. More broadly, the prevalence of rotator cuff abnormalities increased with age and up to 62% in population more than 80 years old. The pathophysiology of RCT could be attributed to extrinsic factors such as impingement by surrounding tissue and intrinsic factor such as tendon degeneration. According to previous study using histochemical and immunocytochemical techniques, fibrocartilaginous metaplasia, decreasing vascularity and fibroblast numbers were found in rotator cuff tear. Besides, the inflammatory response diminished as the tear size increased. The treatment of RCT includes surgery and non-operative treatment. The prognosis depends on the symptoms, tear size, chronicity and other structures involvement. Previous meta-analysis study reported that the effectiveness between surgery and conservative treatment is similar in treating RCT. Therefore, relative rest, oral medication, physical therapy and injection therapy were commonly used in first-line treatments. When treating shoulder pain with injection therapy, steroid was often used at first for short-term pain relief and anti-inflammation. However, the potential cytotoxic effect was found and could be harmful in tendon repair. To accelerative the healing process of soft tissue injury, regenerative injection become more popular and expectable over past few years. A meta-analysis study reported the positive long-term effect of prolotherapy and platelet-rich plasma (PRP). More recently, bone marrow concentrate (BMC) and amniotic membrane (AM) have been used in soft tissue repair and many clinical studies are processing.
The study is to investigate the dose-response relationship between load-induced muscle activation (liMA) and load-induced glenohumeral translation (liTr) in patients with rotator cuff tears and asymptomatic control subjects. Furthermore the study is to investigate the in vivo dose-response relationship between additional weight and glenohumeral translation, to understand the biological variation in liTr, the influence of disease pathology on the liTr, the potential compensation by muscle activation and muscle size, and the influence of liTr on patient outcomes.
To predict the prognosis of large-to-massive RCTs and risk of re-tear by ultrasound elastography.
This study is a prospective observational trial. Data of 4 hospitals will be used to find out the efficacy of conservative treatment in rotator cuff tear.
This retrospective study is to investigate the influence of the Greater Tuberosity Angle (GTA) in addition to CSA on patient outcome in patients with rotator cuff tear.
1. The investigators aim to examine the use of IV and oral ketorolac as an adjunctive agent to the standard of care pain protocol for postoperative pain control following arthroscopic rotator cuff repair. 2. The investigators hypothesize that the use of IV and oral ketorolac in addition to the standard of care pain protocol will reduce postoperative opioid consumption following arthroscopic rotator cuff repair.
This study is to evaluate the effect of polydeoxyribonucleotide (PDRN) for healing and fatty degeneration of rotator cuff. The investigators will enroll 130 patients with rotator cuff tear who will undergo arthroscopic rotator cuff repair. 130 patients will be classified into two group. One group (PDRN) will be injected at the repaired cuff with 3cc polydeoxyribonucleotide just after surgery and be injected with another 3ml polydeoxyribonucleotide under ultrasound guidance 2 weeks after the surgery. The other group (CONTROL) will be injected with 3ml normal saline in the same manner.
The objective of this study is to confirm the safety and performance on the EZPass Suture Passer Instrumentation and the Precision Flexible Reamer Instrumentation. Ultimately, clinical performance will be assessed through survey questions that evaluate the safety and performance of these instruments.
The purpose of this study is to compare how accurately a pseudo-telehealth shoulder examination diagnoses rotator cuff tears compared to a regular clinical examination. MRI is used as the gold standard.
