Validity of the handheld Doppler to determine lower-limb blood flow restriction pressure for exercise protocols. J Strength Cond Res XX(X): 000-000, 2018-Handheld (HH) Doppler is frequently used for determining the arterial occlusion pressure during blood flow restriction exercises; however, it is unknown whether the blood flow is occluded when the auscultatory signal is no longer present...

Use of percutaneous clamps are often helpful tools to aid reduction and intramedullary nailing of distal tibial spiral diaphyseal fractures. However, the anterior and posterior neurovascular bundles are at risk without careful clamp placement. We describe our preferred technique of percutaneous clamp reduction for distal spiral tibial fractures with a distal posterolateral fracture spike, with care to protect the adjacent neurovascular structures. We also investigated the relationship between these neurovascular structures and the site of common percutaneous clamp placement...

BACKGROUND: Patella-post impingement (PPI), contact of the patellar component with the tibial post, occurs during deep knee flexion after posterior stabilized total knee arthroplasty (TKA). In a previous pilot study, only two product lines were investigated. The aim of this study was to compare PPI between 12 contemporary posterior stabilized knee prostheses. METHODS: Twelve posterior stabilized knee prostheses were implanted in full-length sawbone models of the femur and tibia using a navigation system...

BACKGROUND: Fracture of a polyethylene tibial post after a posterior stabilized total knee arthroplasty (PS-TKA) is an uncommon but severe complication. We report five cases of non-traumatic fracture of a tibial polyethylene post that occurred with Prolong highly cross-linked polyethylene with the NexGen LPS-Flex total knee prosthesis. METHODS: A Joint Reconstruction database for a high volume arthroplasty unit was used to identify all cases of revision of Prolong polyethylene used in PS-TKA...

PURPOSE: Alterations in patellar height and posterior tibial slope (PTS) are frequently measured radiographic parameters associated with postoperative impairments after total knee arthroplasty (TKA). Few studies correlate the clinical outcome of TKA with the radiological indices. Both the modified Insall-Salvati ratio (mISR) and the Blackburne-Peel ratio (BPR) were hypothesised to correlate with the clinical outcome after TKA. METHODS: A total of 282 computer navigated primary LCS® -TKAs, implanted in our institution from 2008 to 2012, were included...

Intra-articular tibial plateau fractures can present a surgical challenge due to complex injury patterns and compromised soft tissue. The treatment goal is to spare the soft tissue and an anatomical reconstruction of the tibial articular surface. Depending on the course of the fracture, a fracture-specific access strategy is recommended to provide correct positioning of the plate osteosynthesis. While the anterolateral approach is used in the majority of lateral tibial plateau fractures, only one third of the joint surface is visible; however, posterolateral fragments require an individual approach, e...

This is a case report describing the delayed presentation of injury to all three lower extremity infrapopliteal arteries after a 34 year old male sustained multiple gunshot wounds, including one to his left lower extremity. As part of his initial assessment, ankle brachial index was performed and was found to be abnormal. Further work up for this was delayed due to need for emergent trauma laparotomy. After this procedure, more detailed evaluation with CT angiography of the extremity injury was performed...

Semimembranosus avulsion fracture is infrequently reported and is easy to miss on plain radiographs; the mechanism of injury is highly controversial. Initial reports linked it to anterior cruciate ligament and medial meniscal tears. We report an osteochondral semimembranosus avulsion fracture of the posteromedial tibial plateau with associated posterior cruciate ligament rupture. Also described is a novel surgical fixation technique for such osteochondral fractures where the surgical exposure is limited due to the obliquity of the fracture line resulting in a greater involvement of the articular cartilage than the small bony component...

The posterior tibial nerve, located behind the medial malleolus of the ankle, supplies the intrinsic muscles of the foot and most of the skin of the sole. We describe a novel approach for recording from this nerve via a percutaneously inserted tungsten microelectrode, and provide examples of recordings from presumed muscle spindle endings recorded in freely-standing human subjects. The fact that the angular excursions of the ankle joint are small as the foot is loaded during the transition from the seated position to standing means that one can obtain stable recordings of neural traffic in unloaded, loaded and freely standing conditions...

BACKGROUND: Anterior ankle impingement (AAI) results from repetitive microtrauma leading to pain and decreased dorsiflexion due to spur formation and synovial hypertrophy. Information about the prevalence of anterior spur formation in a large population, and the individual contributions of the talus and tibia to osseous impingement, is limited. MATERIALS AND METHODS: A total of 670 ankle specimens from 344 individuals (n=111 females, n=233 males) aged 20 to 40 years at the time of death were examined...

PURPOSE: To investigate the correlation between posterior tibial slope (PTS) and tibial tunnel widening after anterior cruciate ligament reconstruction (ACL-R). METHODS: Twenty-five patients underwent anatomic single-bundle ACL-R using quadriceps tendon autograft. Six months after surgery, each patient underwent high-resolution computed tomography (CT). Tibial tunnel aperture location was evaluated using a grid method. Medial and lateral PTS (°) was measured based on a previously described method...

Recurrent multidirectional shoulder instability is a difficult clinical problem. This can be compounded in patients with connective tissue diseases such as Ehlers-Danlos syndrome. We present an all-arthroscopic technique involving extra-articular anterior and posterior glenoid bone grafting to augment a capsular repair in a patient with Ehlers-Danlos syndrome and recurrent multidirectional shoulder instability. Graft options include either distal tibial allograft or iliac crest autograft. Anterior graft placement uses a dilated far medial portal using an inside-out technique...

Posterior cruciate ligament (PCL) ruptures account for 1% to 44% of all acute ligament injuries of the knee. In this paper we wanted to try out a system for femural fixation. Hamstring tendons are harvested and standard tibial tunnel is prepared using the transtibial PCL guide; by identifying the PCL footprint, the femoral half tunnel 27 to 30 mm with in-out technique is performed. The femoral rod of a curve cross-pin system is inserted into the anterolateral access within the femoral half tunnel. The guide block is placed 2...

BACKGROUND: Mobilisation with movement treatment techniques have been used to increase the range of motion following pathologies associated with shoulder, elbow and ankle joints. Lack of posterior tibial glide and reflex muscle inhibition are common physical impairments in individuals with post-traumatic stiffness of the knee joint. Current evidence is lacking for the benefits of mobilisation with movement treatment techniques for the knee joint disorders. OBJECTIVE: The purpose of this study was to investigate the short-term effects of mobilisation with movement techniques following post-traumatic stiffness of the knee joint...

Surgical repair of tendons of the foot and ankle is performed utilizing various methods, including autografts, allografts, and synthetic grafts. Artelon is a synthetic biomaterial that is fabricated from wet-spun fibers of PCL-based polyurethane urea, and has, optimal mechanical properties compared with other grafting options. Because of excellent results of Artelon in ACL reconstruction, its use was explored in 3 foot and ankle cases: repair of Achilles, posterior tibial, and peroneal tendons. Artelon has proven to be a successful alternative for tendon repairs, with all 3 cases returning to full function within 8 to 16 weeks and with no complications related to the graft...

PURPOSE: Dynamic intraligamentary stabilization (DIS) is a primary repair technique for acute anterior cruciate ligament (ACL) tears. For internal bracing of the sutured ACL, a metal spring with 8 mm maximum length change is preloaded with 60-80 N and fixed to a high-strength polyethylene braid. The bulky tibial hardware results in bone loss and may cause local discomfort with the necessity of hardware removal. The technique has been previously investigated biomechanically; however, the amount of spring shortening during movement of the knee joint is unknown...

Retrograde intramedullary nailing (RIMN) has been used for periprosthetic fracture of the distal femur after total knee arthroplasty (TKA), yielding good fracture union rates and satisfactory outcomes. However, RIMN for posterior-stabilized- (PS-) TKA risks malpositioning the entry point and disturbing the post of the tibial insert, and the surgeon therefore usually requires knee joint arthrotomy. We report a case of a 79-year-old male who was involved in bicycle accident resulting in periprosthetic fracture of the distal femur after PS-TKA...

Motor imagery (MI), the mental simulation of an action, influences the cortical, corticospinal, and spinal levels, despite the lack of somatosensory afferent feedbacks. The aim of this study was to analyze the effect of MI associated with somatosensory stimulation (SS) on the corticospinal and spinal excitabilities. We used transcranial magnetic stimulation and peripheral nerve stimulation to induce motor-evoked potentials (MEP) and H-reflexes, respectively, in soleus and medialis gastrocnemius (MG) muscles of the right leg...
