From the histological point of view, fascia lata is a dense connective tissue. Although extracellular matrix is certainly the most predominant fascia's feature, there are also several cell populations encountered within this structure. The aim of this study was to describe the existence and characteristics of fascia lata cell populations viewed through a transmission electron microscope. Special emphasis was placed on telocytes as a particular interstitial cell type, recently discovered in a wide variety of tissues and organs such as the heart, skeletal muscles, skin, gastrointestinal tract, uterus and urinary system. The conducted study confirmed the existence of a telocyte population in fascia lata samples. Those cells fulfil main morphological criteria of telocytes, namely, the presence of very long, thin cell processes (telopodes) extending from a relatively small cell body. Aside from telocytes, we have found fibroblasts, mast cells and cells with features of myofibroblastic differentiation. This is the first time it has been shown that telocytes exist in human fascia. Currently, the exact role of those cells within the fascia is unknown and definitely deserves further attention. One can speculate that fascia lata telocytes likewise telocytes in other organs may be involved in regeneration, homeostasis and intracellular signalling.

Arthroscopic-Assisted Lower Trapezius Tendon Transfer With Fascia Lata Autograft for Irreparable Posterior-Superior Rotator Cuff Tears.

Lower trapezius tendon transfer is a surgical procedure that has become increasingly popular in recent years. The biggest advantage of this method is that the pulling direction of the lower trapezius is the same as that of the infraspinatus. Thus, the transferred lower trapezius tendon can biomechanically mimic the functions of the posterior-superior rotator cuff.

Introduction: Regional anesthesia, specifically fascia iliaca compartment blocks (FICB), is highly effective in managing pain, especially in military settings. However, a significant barrier to its implementation is the lack of provider confidence in performing ultrasound-guided procedures. This study evaluates the ability of physician assistant (PA) students, who are often first-line providers in austere locations, to identify the fascia iliaca compartment (FIC) using point-of-care ultrasound (POCUS) after a brief training session and assesses their retention of this skill over a 60- to 90-day period.

Lower lip malposition can occur after anterior mandibular resection as a result of the loss of soft tissue lip attachments. We report our technique of cranial suspension of the lower lip with fascia lata slings to improve lip position. Correction of lip ptosis results in cessation of drooling, improved oral intake, and restoration of facial aesthetics.

Article Synopsis
- Patients with penile defects, whether congenital or acquired, experience significant psychological distress, and the free radial artery forearm flap method has emerged as a preferred technique for reconstruction.
- A retrospective study over 16 years reviewed various cases, modifying the initial design to enhance urethral function and stability in the procedure.
- Results indicated that most patients regained sensation and could urinate standing; however, some experienced complications, and aesthetic outcomes varied, highlighting the technique's potential for effective rehabilitation.
