BACKGROUND: Cervical total disc replacement was developed to preserve motion and reduce adjacent-level degeneration relative to fusion, yet concerns remain that total disc replacement will lead to altered facet joint loading and long-term facet joint arthrosis. This study is intended to evaluate changes in facet contact force, pressure and surface area at the treated and superior adjacent levels before and after discectomy, disc replacement, and fusion. METHODS: Ten fresh-frozen human cadaveric cervical spines were potted from C2 to C7 with pressure sensors placed into the facet joints of C3-C4 and C4-C5 via slits in the facet capsules...

Objectives: During orthodontic tooth movement (OTM), human periodontal ligament fibroblasts (hPDLFs) sense, and respond to mechanical forces. Since the molecular constituents involved in these processes are not fully elucidated, the objective of the present study was to identify further key molecules of the cellular strain response. Materials and Methods: Primary hPDLFs were strained with a static equiaxial strain of 2.5 per cent for 15 minutes, 1 hour, 6 hours, and 24 hours...

Pelvic organ prolapse is a fairly common condition that imposes significant symptoms, diminished quality of life, social burden, financial expense, and surgical risk on women. As evidence supporting the benefit of pelvic floor muscle training in non-surgical management of pelvic organ prolapse grows, physical therapists are becoming a provider of choice interacting with women affected by pelvic organ prolapse. This perspective will review recent research on tissue characteristics of three key components of pelvic organ support: skeletal muscle, ligament, and the vaginal wall...

The observation of pups born from recipient and donor mice after ovariectomy followed by ovarian transplant poses the interesting possibility of an extra-ovarian source of oocytes. However, whether mammalian adult oocytes reside in extra-gonadal tissues remains elusive. Using transgenic fluorescent reporter mice and transplantation surgeries, we demonstrate the presence of both donor- and recipient-derived corpora lutea and recovery of both donor- and recipient-derived offspring from ovariectomized mice after transplantation of donor ovaries...

BACKGROUND: Hypertrophy of the ligamentum flavum (LF) has been considered as a major cause of lumbar central spinal stenosis (LCSS). Previous studies have found that ligamentum flavum thickness (LFT) is correlated with aging, disc degeneration, and lumbar spinal stenosis. However, hypertrophy is different from thickness. Thus, to evaluate hypertrophy of the whole LF, we devised a new morphological parameter, called the ligamentum flavum area (LFA). OBJECTIVES: We hypothesized that the LFA is a key morphologic parameter in the diagnosis of LCSS...

BACKGROUND: Platelet rich plasma (PRP) has been used for decades to facilitate surgical tissue repair; therefore, the current trend of percutaneously injecting PRP to theoretically enhance tissue regeneration and repair is a logical progression. Applications include treatment of osteoarthritis, tendinopathy, chondropathy, acute and chronic soft tissue injuries, muscle or ligament tear, as well as enhancement of healing after bone or tissue reconstruction. However, there is limited evidence to support the use of PRP in the abovementioned conditions...

BACKGROUND: Dislocation of the proximal tibiofibular joint is a complex injury that is often overlooked or misdiagnosed. Surgical management is recommended for severe acute or for chronic symptomatic instability of the proximal tibiofibular joint. Although the anterior ligamentous complex has been reported to be stronger than the posterior complex, biomechanical data are lacking. PURPOSE: To determine the ultimate load of the anterior and posterior ligamentous complexes of the proximal tibiofibular joint to determine optimal graft selection...

Little is known about local and systemic biomarkers in relation to synovitis and pain in end-stage osteoarthritis (OA) patients. We investigated the associations between the novel extracellular matrix biomarker, C1M, and local and systemic interleukin 6 (IL-6) with synovitis and pain. Serum C1M, plasma and synovial fluid IL-6 (p-IL-6, sf-IL-6) were measured in 104 end-stage knee OA patients. Contrast-enhanced magnetic resonance imaging (MRI) was used to semi-quantitatively assess an 11-point synovitis score; pain was assessed by the Western Ontario & McMaster Universities Osteoarthritis Index (WOMAC) and the Neuropathic Pain Questionnaire (NPQ)...

Lisfranc injury fixation or arthrodesis typically involves the reduction and fixation of several tarsometatarsal joints with either screws or a plate and screw constructs. A successful fixation or arthrodesis of the Lisfranc joint requires proper screw placement from the medial cuneiform to the base of the second metatarsal. This is typically done free-hand; however, we describe use of an anterior cruciate ligament guide to help maintain reduction and assist with drill trajectory for more accurate screw or suture button construct placement...

OBJECTIVES: Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues...

A hinged external fixator is used to allow early knee rehabilitation in case of injury or trauma, as an alternative approach to immobilization. It is mainly adopted for the treatment of dislocations, which involve tearing of the ligaments, and it basically consists of two links connected to each other by a revolute joint. Each link is fixed to the femur and tibia via pin fixation, and the revolute joint is approximately aligned to the knee flexion-extension (FE) axis. The advantage in its implantation is to protect ligament reconstruction, while allowing for an aggressive rehabilitation...

BACKGROUND: Caudal blocks are performed through the sacral hiatus in order to provide pain control in children undergoing lower abdominal surgery. During the block, it is important to avoid advancing the needle beyond the sacrococcygeal ligament too much to prevent unintended dural puncture. This study used demographic data to establish simple guidelines for predicting a safe needle depth in the caudal epidural space in children. METHODS: A total of 141 children under 12 years old who had undergone lumbar-sacral magnetic resonance imaging were included...

BACKGROUND: Purpose and hypothesis: Patellar ligament rupture is a rare disabling pathology requiring a surgical ligament suture protected by a frame. The gold standard is the steel cable, but its rigidity and the necessity of a surgical re-intervention for its removal render it unsatisfactory. The objective of this paper is to quantify the mechanical protection provided by the terylene® in comparison with steel. METHODS: Twenty-four knees of 12 fresh frozen cadaveric subjects were divided into 2 homogeneous groups (terylene and steel) of 12 knees (mean age = 69...

REVIEW
Keith Baar
Musculoskeletal injuries account for more than 70% of time away from sports. One of the reasons for the high number of injuries and long return to play is that we have only a very basic understanding of how our training alters tendon and ligament (sinew) structure and function. Sinews are highly dense tissues that are difficult to characterize both in vivo and in vitro. Recently, engineered ligaments have been developed in vitro using cells from human anterior cruciate ligaments or hamstring tendons. These three-dimensional tissues can be grown in a laboratory, treated with agents thought to affect sinew physiology, and then mechanically tested to determine their function...

OBJECTIVES: To investigate the conformation of the proximal tibia in small breed dogs with and without cranial cruciate ligament disease (CCLD) and to identify morphologic abnormalities that may predispose to development of CCLD. METHODS: Mediolateral radiographs of the entire tibia of dogs <15 kg with surgically confirmed CCLD were retrospectively evaluated. Proximal tibial width (PTW), tibial plateau length (TPL), tibial plateau angle as described by Slocum and Slocum (sTPA), proximal tibial tuberosity angle (PTTA), tibial plateau angle as described by Inauen and colleagues (nTPA), and diaphyseal tibial width (DTW) were measured...

BACKGROUND: Although most pediatric Chance fractures (PCFs) can be treated successfully with casting and bracing, some PCFs cause progressive spinal deformities requiring surgical treatment. There are only few reports of asymmetrical osteotomy for PCF-associated spinal deformities. CASE PRESENTATION: We here report a case of a 10-year-old girl who suffered an L2 Chance fracture from an asymmetrical flexion-distraction force, accompanied by abdominal injuries. She was treated conservatively with a soft brace...

Tissue engineering is an attractive strategy for tendon/ligament-to-bone interface repair. The structure and extracellular matrix composition of the interface are complex and allow for a gradual mechanical stress transfer between tendons/ligaments and bone. Thus, scaffolds mimicking the structural features of the native interface may be able to better support functional tissue regeneration. In this study, we fabricated biphasic silk fibroin scaffolds designed to mimic the gradient in collagen molecule alignment present at the interface...
