Efficacy of the Combined Administration of Systemic and Intra-Articular Tranexamic Acid in Total Hip Arthroplasty Secondary to Femoral Neck Fracture: A Retrospective Study.

Adv Orthop 2020 14;2020:9130462. Epub 2020 Apr 14.

Department of Orthopedic Surgery and Traumatology, Saint George Hospital University Medical Center, Balamand University, P.O. Box 166378, Achrafieh, Beirut 1100 2807, Lebanon.

Background: Total hip arthroplasty (THA) is associated with substantial blood loss in the postoperative course. Tranexamic acid (TXA) is a potent antifibrinolytic agent, routinely administered by intravenous (IV) and topical (intra-articular, IA) route, which can possibly interrupt the cascade of events due to hemostatic irregularities close to the source of bleeding. However, scientific evidence of combined administration of TXA in THA secondary to a femoral neck fracture is still meagre. Read More

Minimally Invasive Carpal Tunnel Release (CTR) Using the Wongsiri Technique with MiniSURE.

Adv Orthop 2020 4;2020:6273723. Epub 2020 Jan 4.

Department of Orthopaedic Surgery, Faculty of Medicine, Prince of Songkla University, Hat Yai, Thailand.

Introduction: The standard open technique for carpal tunnel surgery has wound problems and complications significantly more than minimally invasive surgery using the Wongsiri technique with MiniSURE Kit® (Surgical Innovation Healthcare Co., Ltd, Bangkok, Thailand) and in particular, the open technique surgery requires a longer time for return to work. CTR surgery with endoscopic devices improves the results with fewer wound problems when compared with the commonly used open technique; however, nerve complications and injury are more prevalent with endoscopic surgery than with the open technique.

Not All SLAPs Are Created Equal: A Comparison of Patients with Planned and Incidental SLAP Repair Procedures.

Adv Orthop 2019 31;2019:9013935. Epub 2019 Oct 31.

Associate Professor, University of Chicago Medicine, Department of Orthopaedic Surgery and Rehabilitation Medicine, Chicago, IL, USA.

Background: Epidemiological studies have shown a progressive increase in the rate of superior labrum anterior-posterior (SLAP) repair surgery after the year 2000. However, it is not clear whether this is due to increased recognition of isolated SLAP tears or increased SLAP repair performed secondarily during arthroscopy for other purposes.

Hypothesis/purpose: We hypothesized that both isolated SLAP repair and secondary SLAP repair increased with time and that patient age influenced the pathway to SLAP diagnosis and surgery-such that younger patients were more likely to have isolated SLAP repair surgery after being diagnosed in clinic.

Knee-Hip-Spine Syndrome: Improvement in Preoperative Abnormal Posture following Total Knee Arthroplasty.

Adv Orthop 2019 1;2019:8484938. Epub 2019 Jul 1.

Department of Orthopaedic Surgery, Nippon Medical School, 1-1-5 Sendagi, Bunkyo-ku, Tokyo 113-8603, Japan.

An ergonomic upright body posture is maintained by the alignment of the spine, pelvis, and lower extremities, and the muscle strength of body trunk and lower extremities. The posture varies with age because of the degenerative changes in the involved structures and the weakening of the muscles. The compensatory mechanisms underlying these changes have recently been evaluated, and the loss of lumbar lordosis results in spinal kyphosis, pelvic retroversion, hip extension, knee flexion, and ankle dorsiflexion.

A Dynamic Model of Hip Joint Biomechanics: The Contribution of Soft Tissues.

Authors:
Joseph F Fetto

Adv Orthop 2019 4;2019:5804642. Epub 2019 Jun 4.

The Brooklyn Hospital Medical Center, Brooklyn, NY 11201, USA.

Before recent advances in computer modeling technology, it has been nearly impossible to define the contribution of soft tissue structures when constructing models of the body, and in particular the lower extremity. For almost 100 years, the design and fixation of femoral components for total hip arthroplasty (THA), whether cemented or press fit, have been predicated on the Koch model of hip biomechanics. A more comprehensive model, which includes the dynamic contribution of soft tissues, has expanded the Koch's static model. Read More

Possible Improvement of the Sagittal Spinopelvic Alignment and Balance through "Locomotion Training" Exercises in Patients with "Locomotive Syndrome": A Literature Review.

Adv Orthop 2019 8;2019:6496901. Epub 2019 Apr 8.

Department of Orthopaedic Surgery, Kobe University Graduate School of Medicine, Kobe 650-0017, Japan.

On the basis of rapid population aging, in 2007, the Japanese Orthopaedic Association (JOA) proposed a new disease concept "locomotive syndrome" as a degenerative condition of reduced mobility due to the impairment of the musculoskeletal system. Worsened locomotive components, which consist of bones, joints, and intervertebral discs, and muscles and nerves, can lead to symptoms such as pain, limited range of motion, malalignment, impaired balance, and difficulty in walking, ultimately resulting in the requirement of nursing care. "Locomotive syndrome" has gained increased interest in Japan but still not worldwide. Read More

Predicting Success of Two-Stage Exchange for Prosthetic Joint Infection Using C-Reactive Protein/Albumin Ratio.

Adv Orthop 2019 2;2019:6521941. Epub 2019 May 2.

Duke University Medical Center, Durham, NC, USA.

Two-stage exchange is most commonly used for treatment of prosthetic joint infections (PJI) but, this may fail to eradicate infections. C-reactive protein/albumin ratio (CAR) has been used to predict survival and operative success in other surgical subspecialties and so, we assess the association between CAR and reimplantation success during two-stage revision for PJI defined by the Musculoskeletal Infection Society following a primary total hip (THA) or knee (TKA) arthroplasty. From January, 2005 to December, 2015, two institutional databases were queried and patient demographics, antibiotic duration, C-reactive protein, and albumin were collected prior to reimplantation.

Immediate Physical Therapy following Total Joint Arthroplasty: Barriers and Impact on Short-Term Outcomes.

Adv Orthop 2019 8;2019:6051476. Epub 2019 Apr 8.

Department of Orthopaedic Surgery, Duke University Hospital, Durham, NC 27710, USA.

Background: Recent evidence suggests benefit to receiving physical therapy (PT) the same day as total joint arthroplasty (TJA), but relatively little is known about barriers to providing PT in this constrained time period. We address the following questions: (1) Are there demographic or perioperative variables associated with receiving delayed PT following TJA? (2) Does receiving immediate PT following TJA affect short-term outcomes such as length of stay, discharge disposition, or 30-day readmission? . Primary TJA procedures at a single center were retrospectively reviewed. Read More

Prevalence of Anterior Femoral Neck Osteophyte in a Total Hip Arthroplasty Population: Analysis of Preoperative Surgical Plans.

Adv Orthop 2019 3;2019:5193945. Epub 2019 Mar 3.

Melbourne Orthopaedic Group, Windsor, VIC, Australia.

Despite strongly positive results of total hip arthroplasty (THA), patients remain at risk for complications including dislocation. Spinopelvic motion and the hip-spine relationship have been recognized as important factors in surgical planning and implant positioning in THA. Periarticular osteophytes are one of the hallmark pathoanatomic features of osteoarthritis and may influence implant positioning and joint stability; residual osteophytes at the anterior femoral neck may cause anterior impingement and posterior instability.

Compensatory Function of the Subtalar Joint for Lower Extremity Malalignment.

Adv Orthop 2019 24;2019:7656878. Epub 2019 Feb 24.

Orthopaedic Foot and Ankle Center, Shiseikai Daini Hospital, 5-19-1 Kamisoshigaya, Setagaya-ku, Tokyo, 157-8550, Japan.

It is important to evaluate the subtalar joint and hip-knee-ankle alignment to understand lower extremity alignment. In this review, we focused on the compensatory changes in the subtalar joint alignment for the deformity of the knee and ankle joint, reviewing previous research. The subtalar joint alignment was compensatory valgus in patients with varus knee and ankle deformity, whereas it was uncertain whether the subtalar joint alignment was compensatory varus in patients with valgus knee and ankle deformity.

Intra- and Extra-Articular Deformity of Lower Limb: Tibial Condylar Valgus Osteotomy (TCVO) and Distal Tibial Oblique Osteotomy (DTOO) for Reconstruction of Joint Congruency.

Adv Orthop 2019 18;2019:8605674. Epub 2019 Feb 18.

Department of Traumatology Fukushima Medical University, Trauma and Reconstruction Center, Southern Tohoku General Hospital, Fukushima, Japan.

Osteotomies are the established surgical procedure for the deformity of the lower limb induced by osteoarthritis (OA) of the knee and ankle. Closed-wedge (CW) and open-wedge (OW) high tibial osteotomy (HTO) are extra-articular surgery, which aim to shift the mechanical axis from medial to slightly lateral and reduce the overload in the medial compartment of the varus deformed knee by extra-articular correction. However, varus deformity of the knee with the teeter effect, which could be accompanied with subluxation and thrust due to the medial-lateral soft tissue imbalance, is not resolved only by the shift of mechanical axis.
