Detailed evaluation of 2959 allogeneic and xenogeneic Dense Connective Tissue grafts (fascia lata, pericardium, and dura mater) used in the course of 20 years for duraplasty in neurosurgery
Acta Neurochirurgica, 1997Co-Authors: Jan Pařizek, Pavel Měřicka, Z Husek, Petr Suba, Josef Spacek, Stanislav Němecek, Jana Německova, Miroslav Sercl, P EliasAbstract:Surgical experience with 2959 allogeneic and xenogeneic Dense Connective Tissue grafts (1767 of fascia lata, 909 of pericardium, and 283 of dura mater), used in 2665 neurosurgical operations performed in the course of 20 years (1976 to 1995) is reported. Duraplasty using either allogeneic or xenogeneic grafts has had a similar, and favourable clinical outcome. Nevertheless, the pliable deep frozen fascia lata grafts, which could be used in any location, have been reserved for sella turcica plugging, anterior cranial base plasty, aneurysmal wrapping, and surgery of lipomyelomeningocele. Pericardium and dura mater grafts were in the majority of cases used over the brain convexity and posterior cranial fossa. Ovine pericardium proved to be superior to bovine and allogeneic pericardia because of its workability, flexibility, reduced thickness, and better transparency. Postsurgical complications occurred in 7.3%, and they were: 1) cerebrospinal fluid fistulas in 2.8%; 2) meningites in 2.3% (aseptic 1.4%, bacterial 0.8%, and tumoural 0.1% meningites); 3) pseudomeningoceles in 2.2%; 4) wound infections in 0.6%; 5) malresorptive hydrocephalus in 0.5%; and 6) adhesions to nerve Tissue in 0.5%. The majority of complications healed without surgery. Forty-eight grafts (1.6%) failed to fulfil the requirements of the surgeon, and 46 of them were re-operated upon. Though another thirty-nine grafts healed successfully, 39 shunts (1.5%) had to be performed for malresorptive hydrocephalus (0.9%), and/or for a big pseudomeningocele (0.6%). So, the pure complication rate in 2665 duraplasties was 3.1%. The complex evaluation of the allogeneic and xenogeneic grafts (fascia, pericardium, and dura mater), used for duraplasty in neuro-surgery during the last 20 years proved them, as remarkably good, with a success rates of 96.9%.

orthotic considerations for Dense Connective Tissue and articular cartilage the need for optimal movement and stress
Journal of Hand Therapy, 2012Co-Authors: Pat Mckee, Susan Hannah, Victoria W PrigancAbstract:Orthotic intervention is an essential component of hand rehabilitation, addressing biological factors that affect activity and participation. Functional, pain-free joint mobility requires skeletal stability, healthy articular cartilage, and appropriate extensibility of periarticular Dense Connective Tissues (DCTs). This article addresses basic science underlying clinical reasoning when considering orthoses to maintain or restore structural integrity, mobility and function of DCT structures, and articular cartilage. However, these Tissues often have different and sometimes conflicting requirements for the maintenance and restoration of integrity and health. The duration of immobilization, especially at end range, should be carefully considered, as it impairs nutrition of Tissues and adversely compresses articular cartilage, causing injury that may not be reversible. Immobilization also reduces extensibility of DCT. Thus, an intermittent orthotic wearing schedule is suggested, allowing movement wherever possible to promote Tissue health. To optimize benefits and minimize harmful effects of orthotic intervention, further research on physiological responses of human Tissues to immobilization and tension is needed.

quantitative analysis of gliding between subcutaneous Tissue and the vastus lateralis influence of the Dense Connective Tissue of the myofascia
Journal of Bodywork and Movement Therapies, 2018Co-Authors: Kengo Kawanishi, Shintarou KudoAbstract:Abstract Introduction The thickness of Connective Tissue has been shown to be associated with pain (Stecco et al 2014). However, the relationship between fascial thickness and gliding remains unclear. In addition, the influence between gliding and the motion rhythm and limb position isn’t clear. Method A therapist moved patient’s lower leg at one of two constant rhythms(40 or 60bpm). Gliding of both the vastus lateralis (VL) muscle and subcutaneous (SC) Tissue were recorded during knee motion using ultrasonography.Particle image velocimetry analysis software was adapted to create the flow velocity from echo imaging. Gliding was calculated using a coefficient of correlation from each flow velocity. Myofascial thickness and SC were measured using Image-J. The ratios of the loose Connective Tissue (LCT) and Dense Connective Tissue (DCT) thickness to the total myofascial thickness were calculated. Repeated-measures two-way ANOVA was used to compare the two motion rhythms and three positions, with stepwise multiple regression analysis to analyze the predictors that influenced the gliding coefficient at each rhythm. Results Repeated-measures two-way ANOVA showed that the effect of rhythm was statistically significant, but the effect of position was not. At a 40 bpm rhythm, stepwise multiple regression analysis selected SC thickness and DCT thickness as significant factors, while at a 60 bpm rhythm, SC thickness and DCT ratio were selected. Conclusion This study revealed that increased thickness of DCT of the myofascia and SC resulted in decreased gliding between the VL and SC, demonstrating that gliding is related to fascial thickness. Motion rhythm influences gliding between Tissues.

pressure generated by syringes implications for hydrodissection and injection of Dense Connective Tissue lesions
Scandinavian Journal of Rheumatology, 2011Co-Authors: W A P Hayward, Luke J Haseler, Lawrence G Kettwich, Adrian A Michael, Wilmer L Sibbitt, Arthur D BankhurstAbstract:Objective Hydrodissection and high-pressure injection are important for the treatment of Dense Connective Tissue lesions including rheumatoid nodules, Dupuytren's contracture, and trigger finger. The present study determined the optimal syringes for high-pressure injection of Dense Connective Tissue lesions. Methods Different sizes (1, 3, 5, 10, 20, and 60 mL) of a mechanical syringe (reciprocating procedure device) with a luer-lock fitting were studied. Twenty operators generated maximum pressure with each mechanical syringe size, and pressure was measured in pounds per square inch (psi). Subsequently, 223 Dense Connective Tissue lesions were injected with different sizes of syringes (1, 3, or 10 mL). Outcomes included (i) successful intralesional injection and (ii) clinical response at 2 weeks. Results Smaller syringes generated significantly more injection pressure than did larger syringes: 1 mL (363 ± 197 psi), 3 mL (177 ± 96 psi), 5 mL (73 ± 40 psi), 10 mL (53 ± 29 psi), 20 mL (32 ± 18 psi), and 60 mL (19 ± 12 psi). Similarly, smaller syringes were superior to larger syringes for intralesional injection success: 10 mL: 34% (15/44) vs. 1 mL: 100% (70/70) (p Conclusion Smaller syringes (≤ 3 mL) are superior to larger syringes (≥ 5 mL) for successful hydrodissection and high-pressure intralesional injection of Dense Connective Tissue lesions.
