Wireless In-Ear Communication for Total Joint Arthroplasty: A Simulated Operating Room Evaluation.

Effective communication is vital for patient safety, yet failures are common, often due to outdated methods. This study aimed to assess whether in-ear communication devices improve communication in orthopedic surgery simulations compared to traditional loud voice methods. Fifteen participants underwent simulations using both in-ear wireless devices and standard communication.

Randomized controlled trial of intrathecal oxytocin on speed of recovery after hip arthroplasty.

Recovery from surgery is quicker in the postpartum period, and this may reflect oxytocin action in the spinal cord. We hypothesized that intrathecal injection of oxytocin would speed recovery from pain and disability after major surgery. Ninety-eight individuals undergoing elective total hip arthroplasty were randomized to receive either intrathecal oxytocin (100 μg) or saline.

Closing Time: One Last Call for Patient Preference.

Background: Wound closure method in total hip and knee arthroplasty is a controversial topic with no differences in clinical outcomes between surgical staples (SS) and subcutaneous sutures with Dermabond (SCD). When clinically appropriate, providers should focus more on what the patient may prefer. This study aimed to collect data on patient preference between SS and SCD and analyze differences in preference based on gender and previous surgical histories.

Characterizing Particle Evacuation in the Setting of Positive-pressure Body Exhaust Suit Using a Novel Gloving Technique.

The sterility of the gown-glove interface during total joint arthroplasty is a key factor in preventing contamination of the surgical field. To compare the potential of gown-glove interface contamination with a novel gloving technique versus standard gloving technique. We performed a study quantifying potential gown-glove interface contamination using two different gloving techniques.

Removing Well-Fixed, Collared and Noncollared Tapered Hip Stems Without an Extended Trochanteric Osteotomy Using a Novel Stem Removal System.

Improvements in materials, components, and surgical techniques in cementless total hip arthroplasty are resulting in improved femoral stem fixation through bony ongrowth or ingrowth. While improved femoral stem fixation is one reason for the current excellent total hip survivorship, indications for stem removal such as infection, implant fracture, or osteolysis remain. A commonly used technique for fully ingrown femoral stems is an extended trochanteric osteotomy which can result in comminuted fractures of the proximal femur during stem removal requiring additional fixation.

Noise Exposure and Risk of Noise Induced Hearing Loss to the Adult Reconstruction Surgeon: Recommendations for Prevention and Monitoring.

Goal of the study was to determine the average noise exposure to the orthopaedic surgeon performing hip and knee arthroplasty and the benefit of customized hearing protection. Data from dosimeters (3MTM Edge 4) worn by three adult reconstruction orthopedic surgeons for a total of 27 operative day recordings was analyzed using 3MTM Detection Management Software (product version 2.7.

Synovial Cell Count Poorly Predicts Septic Arthritis in the Presence of Crystalline Arthropathy.

A synovial cell count greater than 50,000/mm is the threshold most commonly used to diagnose septic arthritis. This lab value may be nonspecific in the setting of crystalline arthropathy. The purpose of this study was to evaluate the accuracy of diagnosing septic arthritis using a synovial cell count cut-off of 50,000/mm in the setting of crystalline arthropathy.

Prolonged Weakness and Paresthesia After Revision Total Hip Arthroplasty in a Patient with Sickle Cell Anemia Receiving Spinal Anesthesia: A Case Report.

Case: This report describes a case of prolonged neurologic deficit of primarily the nonoperative lower extremity in a patient with sickle cell disease (SCD) who received spinal anesthesia during revision total hip arthroplasty (THA). The patient initially showed bilateral lower extremity neurologic deficits localized to the L5/S1 nerve root, with the eventual persistence of symptoms in the nonoperative extremity for >1 year.

Conclusions: This report describes an unusual complication after THA and spinal anesthesia.

Factors Influencing Survivorship in Vasculopathic Patients.

Total knee arthroplasty (TKA) in patients with peripheral vascular disease has sparsely been studied. This study examined patient and radiographic factors that could affect reoperation free survival in these patients. We retrospectively reviewed TKA procedures performed in patients with nonpalpable pulses on physical examination between January 1, 2004, and December 31, 2013.

Alternative technique for knee manipulation under anesthesia.

Total knee arthroplasty is a successful surgery for the majority of patients with osteoarthrosis of the knee. Approximately 5% of patients undergoing total knee arthroplasty experience loss of motion or arthrofibrosis. Manipulation under anesthesia (MUA) is generally indicated for patients who do not achieve >90° of flexion by 6-12 weeks postoperatively.

Utility of Radiographs, Computed Tomography, and Three Dimensional Computed Tomography Pelvis Reconstruction for Identification of Acetabular Defects in Residency Training.

Purpose: The Paprosky classification system of acetabular defects is complex and its reliability has been questioned. The purpose of this study was to evaluate the effectiveness of different radiologic imaging modalities in classifying acetabular defects in revision total hip arthroplasty (THA) and their value of at different levels of training.

Materials And Methods: Bone defects in 8 revision THAs were classified by 2 fellowship-trained adult reconstruction surgeons.

Cost Analysis of Sending Routine Pathology Specimens following Total Joint Arthroplasty in the Age of Bundled Payments.

Bundled payment plans are being developed as a means to curb healthcare spending. Routine histology following total hip arthroplasties (THA) and total knee arthroplasties (TKA) is standard practice at many institutions. Recently, the value of this practice has been questioned as histologic diagnoses in THA and TKA rarely differ from the clinical diagnoses.

Bundled payments in total joint arthroplasty and spine surgery.

Purpose Of Review: The goal of this manuscript is to provide an overview and analysis of bundled payment models for joint replacement and select spine procedures. Advantages and disadvantages of bundled payment models will be discussed.

Recent Findings: In select populations, bundled payment models have been shown to reduce costs while maintaining satisfactory outcomes.

A Bundle Protocol to Reduce the Incidence of Periprosthetic Joint Infections After Total Joint Arthroplasty: A Single-Center Experience.

Background: Periprosthetic joint infection (PJI) represents a devastating complication of total hip arthroplasty (THA) or total knee arthroplasty (TKA). Modifiable patient risk factors as well as various intraoperative and postoperative variables have been associated with risk of PJI. In 2011, our institution formulated a "bundle" to optimize patient outcomes after THA and TKA.

Functional Outcomes After Both Bone Forearm Fractures in Adults.

The purpose of this study was to evaluate midterm outcomes after both bone forearm fractures. A retrospective review of patients treated with open reduction and internal fixation (ORIF) at three level 1 trauma centers was completed. Eligible patients were sent three questionnaires: Disabilities of the Arm, Shoulder and Hand (DASH), Short Form-12 (SF-12), and questions about postinjury experience.

A useful tool for retained washer retrieval when removing iliosacral screws.

Iliosacral screw removal is occasionally necessary during index or revision pelvic ring surgery. This procedure can necessitate a two-step process: screw removal followed by retained washer removal. On attempted removal of the screw-washer complex, the washer will not uncommonly dissociate itself from the screw.

Distal locking using an electromagnetic field-guided computer-based real-time system for orthopaedic trauma patients.

Objectives: To compare the efficacy of distal interlocking during intramedullary nailing using a freehand technique versus an electromagnetic field real-time system (EFRTS).

Design: A prospective, randomized controlled trial.

Setting: Level I academic trauma center.

Microvascular effects of subatmospheric pressure in striated muscle.

Objective: Topical application of subatmospheric pressure (TASAP) promotes faster wound healing, but tissue effects are not entirely understood. This study investigated microvascular effects of TASAP in striated muscle with the hypothesis being that TASAP elicits arteriolar vasodilation and decreases interstitial accumulation of protein.

Methods: Rat cremasteric microcirculation was directly examined in two experiments utilizing a novel technique.

Management of humeral shaft fractures.

Humeral shaft fractures account for approximately 3% of all fractures. Nonsurgical management of humeral shaft fractures with functional bracing gained popularity in the 1970s, and this method is arguably the standard of care for these fractures. Still, surgical management is indicated in certain situations, including polytraumatic injuries, open fractures, vascular injury, ipsilateral articular fractures, floating elbow injuries, and fractures that fail nonsurgical management.

Vascular injury associated with extremity trauma: initial diagnosis and management.

Vascular injury associated with extremity trauma occurs in <1% of patients with long bone fracture, although vascular injury may be seen in up to 16% of patients with knee dislocation. In the absence of obvious signs of vascular compromise, limb-threatening injuries are easily missed, with potentially devastating consequences. A thorough vascular assessment is essential; an arterial pressure index <0.
