Summary
Lower trapezius tendon transfer effectively treats irreparable infraspinatus tears, restoring shoulder function and alleviating pain. This surgical approach offers a promising solution for complex rotator cuff injuries.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Research
- Reconstructive Surgery
Background:
- Irreparable isolated musculotendinous lesions of the infraspinatus significantly impair shoulder function.
- These lesions present challenges due to rapid architectural changes, including atrophy and fatty infiltration.
Observation:
- A case report details two patients (57-year-old female, 66-year-old male) with irreparable isolated infraspinatus musculotendinous lesions.
- Both patients underwent lower trapezius tendon transfer for treatment.
Findings:
- Lower trapezius transfer effectively alleviated pain in both patients.
- The procedure restored active external rotation, contrasting with previous treatment attempts.
Implications:
- Lower trapezius tendon transfer is a viable and effective surgical option for irreparable infraspinatus tears.
- This technique offers biomechanical and anatomical advantages over traditional methods for rotator cuff reconstruction.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:22Burn Injuries
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
