The fascicular architecture of skeletal muscle dictates functional parameters such as force production and contractile velocity. Muscle microarchitecture is typically determined by means of manual dissection, a technique that is inherently destructive to specimens. Furthermore, fascicle lengths and pennation angles are commonly assessed at only a limited number of sampling sites per muscle. We present the results of a digital technique to non-destructively assess muscle architectural variables for three jaw-adductor muscles within a specimen of the cercopithecine primate Macaca fascicularis (crab-eating macaque)...

The tradeoff between force and velocity in skeletal muscle is a fundamental constraint on vertebrate musculoskeletal design (form:function relationships). Understanding how and why different lineages address this biomechanical problem is an important goal of vertebrate musculoskeletal functional morphology. Our ability to answer questions about the different solutions to this tradeoff has been significantly improved by recent advances in techniques for quantifying musculoskeletal morphology and movement. Herein, we have three objectives: (1) review the morphological and physiological parameters that affect muscle function and how these parameters interact; (2) discuss the necessity of integrating morphological and physiological lines of evidence to understand muscle function and the new, high resolution imaging technologies that do so; and (3) present a method that integrates high spatiotemporal resolution motion capture (XROMM, including its corollary fluoromicrometry), high resolution soft tissue imaging (diceCT), and electromyography to study musculoskeletal dynamics in vivo...

The jaw adductor muscles of extinct mammals are often reconstructed to elucidate paleoecological relationships and to make broad comparisons among taxa. Muscle lever arms, bite load arms, muscle dimensions, and gape are often also reconstructed to better understand feeding. Several different approaches to these and related goals are discussed here. A protocol for reconstructing muscle dimensions and bite force using biomechanically informative skull measurements and osteological proxies of muscle dimensions is described and applied to a case study of subfossil Malagasy lemurs...

BACKGROUND: Major congenital malformations affect up to 3% of newborns. Infants with prenatally diagnosed soft tissue defects should benefit from having autologous tissue readily available for surgical implantation in the perinatal period. In this study, we investigate fetal subcutaneous cells (fSC) as cellular source for tissue engineering. METHODS: Fetal subcutaneous biopsies were collected from elective terminations at gestational week 20-21. Cells were isolated, expanded and characterized in vitro...

OBJECTIVE: Interdisciplinary work including surgery and additive radiotherapy is often needed for the therapy of tumours. Beneath this, brachytherapy is an important part of the radiotherapy. It was first used over 100 years ago and is in regular use after the development of afterload technology in the early 1970s. Today it is often used in different tumour therapies, for example in soft tissue sarcoma or breast tumours, in order to decrease the risk of local recurrence. Concerning its benefits, higher doses could be used because of the localized effect with equivalent local control rate and less toxicity of treatment...

W Sioen, G Meermans, A Lenaert
Dislocation after total hip arthroplasty (THA) remains a devastating complication and a primary cause for revision arthroplasty. Historical data indicate that a posterior approach is associated with a higher dislocation rate. In this study, we present a highly reliable and anatomical reconstruction, based on the biomechanical findings of a previous cadaveric experiment. The posterior soft tissues were repaired in 2 layers. First a reattachment of the posterior orbicular ligament is performed at the anterior capsule...

Acute traumatic or surgical wounds that cannot be primarily closed often cause substantial morbidity and mortality. This often leads to increased costs from higher material expenses, more involved nursing care, and longer hospital stays. Advancements in soft tissue expansion has made it a popular alternative to facilitate early closure without the need for more complicated plastic surgical procedures. Areas Covered: In this review, we briefly elaborate on the history and biomechanics of tissue expansion and provide comprehensive descriptions of traditional internal tissue expanders and a variety of contemporary external tissue expanders...

REVIEW
Alexander Zimmerer, Christian Sobau, Peter Balcarek
Recent years have been characterized by an ongoing increase in knowledge about the different conditions associated with lateral patellar instability. This increase in knowledge provides differentiated approaches to the various pathologies of the patellofemoral joint. Though current guidelines consider medial patellofemoral ligament (MPFL) reconstruction the basic treatment for the unstable patella, medial soft tissue-stabilizing procedures should not be interpreted as stand-alone procedures in every case. The influence of different anatomical factors leading to patellar instability, as well as their impact on clinical outcome measures, is becoming increasingly apparent and deserves further attention...

BACKGROUND: Reshaping the nose can be achieved following 3 main concepts: preservation and reshaping of normal anatomy, resection of nasal deformities, reconstruction of nasal framework. Time, experience and nasal anatomic knowledge are keys to understand nasal biomechanics. OBJECTIVES: To describe how experience and morphodynamic anatomy lead to a new concept of sequential primary rhinoplasty, resulting in reducing revision rhinoplasties. METHODS: Through 36 years' experience in different rhinoplasty procedures, 25 years in personal anatomic studies of the nose and reviewing the last 15 years including 600 patients who underwent new concepts in primary rhinoplasty out of 1200 patients operated during this period, the author analyzes how nasal anatomic layers, surgical approaches, and morphological effect of the time interact to modify the aesthetic results according to current rhinoplasty concepts...

This case report describes a 55-year-old male patient with type II necrotizing fasciitis (NF) of the hand and forearm. The rapid progression of the tissue infection could be successfully stopped with radical surgical débridement and antibiotic therapy. For the reconstruction of the extensive loss of soft tissue a combination of split-thickness skin graft (STSG) and the synthetic dermal substitute MatriDerm® was used. In cases of NF, MatriDerm® and STSG provide a rapidly available and simple alternative to other reconstruction techniques...

BACKGROUND: Open reduction and internal fixation of Lisfranc injuries has typically used multiple longitudinal incisions or a single transverse incision to approach the tarso-metatarsal joint (TMTJ). The incidence of wound-related complications is considerable. We describe a novel single-incision approach that utilizes subcutaneous windows to the medial TMTJ. METHODS: A retrospective review identified 150 patients who underwent open reduction and internal fixation for Lisfranc injuries, via the modified dorsal approach, at our center between January 2011 and June 2016...

BACKGROUND: Perforator flaps have unique advantages that may overcome the shortcomings of conventional approaches to myelomeningocele reconstruction. However, identifying and dissecting tiny perforators in neonates is arduous. We have overcome these obstacles with a freestyle flap approach that uses duplex ultrasonography to locate perforator vessels, allowing for limited superficial dissection. This report describes the duplex ultrasonography-assisted freestyle pedicled perforator flap technique for closure of myelomeningocele defects, with long-term clinical outcomes...

BACKGROUND: Surgical options for the unreconstructable elbow are limited to arthrodesis, total arthroplasty, or osteoarticular allograft reconstruction. Each of these options is limited by severe functional impairment and/or high complication rates. Vascularized allotransplantation of the elbow joint has the potential to mitigate these complications. In this study, we describe our technique for harvesting the elbow for vascularized joint transplantation and demonstrate the flap's vascularity using contrast angiography...

BACKGROUND: When keratinized tissue width around dental implants is poorly represented, the clinician could resort to autogenous soft tissue grafting. Autogenous soft tissue grafting procedures are usually associated with a certain degree of morbidity. Collagen matrices could be used as an alternative to reduce morbidity and intra-operatory times. The aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants...

INTRODUCTION: Adverse effects in the nasolabial region should be anticipated after Le Fort I osteotomy. Intraoperative factors such as the extent of surgical dissection, type of closure and perinasal soft tissue reconstruction seem to influence soft tissue response. Attempts to control these changes have been made over the years and several techniques have been proposed. MATERIALS AND METHODS: The authors present a minimally invasive alternative surgical technique to control alar base widening as well as lip shortening...
