Impact of Frailty on 30-Day Morbidity and Mortality of Patients With Intertrochanteric Femur Fractures.
Abstract The aim of this study was to evaluate the association between frailty and 30-day morbidity and mortality in patients with intertrochanteric femur fractures. Furthermore, the authors sought to identify a specific frailty index score that would help identify high-risk patients. This retrospective study evaluated 229 consecutive patients 50 years or older who presented to a single level I trauma center for surgical fixation of an intertrochanteric femur fracture. Frailty was determined using a previously validated 11-point modified frailty index (mFI) scale. Primary outcome variables included 30-day morbidit...

Exclusive Posterolateral Arthroscopic and Endoscopic Approaches Used in the Treatment of Lateral Epicondylitis.
Abstract Complications following arthroscopy of the elbow for the treatment of lateral epicondylitis are essentially related to the anterior arthroscopic approach. The principal aims of this study were to describe and evaluate the mixed arthroscopic and endoscopic surgical technique using posterolateral approaches exclusively. This was a retrospective study of consecutive patients operated on between 2005 and 2014 for lateral epicondylitis following more than 6 months of ineffective medical treatment. The exploration was arthroscopic via a distal posterolateral portal. The extensor carpi radialis brevis was disins...

Day of the Week of Surgery Affects Time to Discharge for Patients With Adolescent Idiopathic Scoliosis.
This study examined the effect of this traditional staffing model on time to discharge for patients undergoing posterior spinal instrumentation and fusion for adolescent idiopathic scoliosis. Patients undergoing surgery later in the week had a significantly longer hospital stay compared with patients undergoing surgery early in the week (5.5 days vs 4.9 days, respectively; P=.003). This discrepancy resulted in a mean cost increase of $7749.50 for patients undergoing surgery later in the week. A subsequent quality, safety, value initiative (QSVI) was undertaken to balance physical therapy resources alone. Following the QSVI...

Survival, Tumor Recurrence, and Function Following Shoulder Girdle Limb Salvage at 24 to 35 Years of Follow-up.
Abstract Limb salvage is the treatment of choice for malignant shoulder girdle tumors; however, there is a paucity of data examining the long-term outcome. The authors have previously reported on a cohort of patients at short- and mid-term follow-up. The purpose of this study was to report the long-term outcome of shoulder reconstruction in terms of oncological and functional outcome. The authors reviewed 53 patients who underwent a limb salvage procedure for treatment of a tumor of the shoulder girdle. At a mean of 28 years following the resection, 76% of surviving patients were contacted and administered functio...

Anticoagulation in Revision Total Joint Arthroplasty: A Retrospective Review of 1917 Cases.
Abstract Although several studies now support the use of aspirin for venous thromboembolism (VTE) prophylaxis in primary total hip arthroplasty (THA) and total knee arthroplasty (TKA), the optimal chemoprophylactic agent in revision THA and TKA is not clear. The purpose of this study was to determine if the type of chemoprophylaxis has an effect on the VTE rate in patients undergoing revision total joint arthroplasty (TJA). The second aim was to compare differences in rates of wound drainage in primary and revision TJA stratified by the postoperative chemoprophylaxis used. The authors retrospectively reviewed 1917...

Early Results of a Modern Uncemented Total Knee Arthroplasty System.
Abstract Historically, cementless total knees were associated with early failure, which made cemented total knee arthroplasty the gold standard. Manufacturers have introduced newer uncemented technologies that provide good initial stability and use highly porous substrates for bony in-growth. The authors hypothesized that the implants would have equivalent 90-day clinical and economic outcomes. Prospectively collected data on 252 uncemented knees in the Michigan Arthroplasty Registry Collaborative Quality Initiative database were reviewed.

Two-Stage Treatment for Ankylosing Spondylitis With Severe Hip Contracture.
Abstract Ankylosing spondylitis is a progressive inflammatory disease that often involves the hip, causing deformities and dysfunction. Total hip arthroplasty (THA) may be used, but contracture of the hip joint in ankylosing spondylitis makes THA technically difficult and leads to poor efficacy. This retrospective study describes a novel 2-stage surgical treatment for ankylosing spondylitis of the hip and evaluates its efficacy relative to THA alone. Patients with ankylosing spondylitis and severe hip flexion contracture treated between 2011 and 2017 were assigned to either an experimental group or an age-matched ...

Advanced Baseball Metrics Indicate Significant Decline in MLB Pitcher Value After Tommy John Surgery.
Abstract There are conflicting reports regarding the efficacy of Major League Baseball (MLB) pitchers following medial ulnar collateral ligament reconstruction (UCLR). As advanced baseball metrics have revolutionized the way general managers define pitchers' value, the authors believe that these should be used to measure clinical outcomes after UCLR. All MLB pitchers who underwent UCLR from April 1, 1991, through July 1, 2016, were compiled (N=253). Pitcher demographics and statistics were collected for up to 3 full seasons preceding and following surgery. Data for pitching controls (all MLB [AMLB] pitchers) were ...

The Effect of Femoral Cutting Jig Design on Restoration of Femoral Offset in Posterior-Referenced Total Knee Arthroplasty.
Abstract Femoral component sizing and rotation in total knee arthroplasty (TKA) affects patellofemoral tracking and tibiofemoral mechanics. Posterior referencing is said to optimize restoration of posterior condylar offset. However, it typically allows the surgeon to select 3° to 5° of external rotation to the posterior condylar axis, inevitably changing the offset of one or both condyles. The axis about which external rotation occurs varies between the jigs of various TKA systems. The location of this axis can result in a medial, central, or lateral reference point for posterior offset restoration. Variat...

Use of a Suture Button Device to Correct Syndesmotic Malreduction Caused by a Trans-Syndesmotic Screw.
This report describes the replacement of a rigid syndesmotic screw with a flexible suture button fixation device to correct fibular translation and tibiotalar malalignment related to screw contact with other tibial implants. Suture button devices, although more expensive, can result in less postoperative malreduction and lead to better functional outcomes. As seen in these cases, careful attention should be given to syndesmotic or tibiotalar reduction after screw placement around other tibial implants, and the screw can be exchanged to a suture button device to address malreduction, if needed.

Frailty Index Is Associated With Periprosthetic Fracture and Mortality After Total Knee Arthroplasty.
Abstract This cohort study of adult (≥50 years) patients aimed to calculate a validated, preoperative frailty deficit index (FI) and used it to compare outcomes following total knee arthroplasty (TKA), primary and revision, from 2005 through 2016. Using multivariable logistic and Cox regression, the authors analyzed whether FI, adjusted for age, predicts outcomes prior to hospital discharge, within 90 days, and within 365 days. They classified 9818 patients undergoing TKA (7920 primary and 1898 revision; median age, 69 years) as frail (21%), vulnerable (39%), and non-frail (40%). Frail, relative to non-frail, p...

Diagnosis and Management Strategies for Distal Biceps Rupture.
Abstract Rupture of the distal biceps tendon most commonly is secondary to mechanical overload during eccentric muscle contraction. Due to deficits of strength and endurance, surgical repair usually is recommended. Although both single- and double-incision approaches have been described, double-incision techniques have been shown to better re-create the native anatomic insertion. However, excellent and comparable clinical outcomes have been demonstrated with both techniques. Fixation with a cortical button and interference screw has been shown to be the strongest construct biomechanically; however, several modern ...

Despite the Safety of Preoperative Cefazolin for Patients With Non-anaphylactic Penicillin Allergy, 20% of Practitioners Avoid Its Use.
Abstract Cefazolin is commonly used for surgical site infection prophylaxis due to its low cost and effective coverage. However, it is controversial to use cefazolin in patients with a penicillin allergy despite the cross-reactivity between cefazolin and penicillin being only 1%. Ample literature shows that it is safe to use cefazolin in patients with non-anaphylactic penicillin allergies. However, there is often hesitation by anesthesiologists or orthopedists when prescribing this medication in this population. The current authors sent a 16-question survey to all the residency programs in the United States in ane...

Total Talectomy and Reconstruction Using a 3-dimensional Printed Talus Prosthesis for Ewing's Sarcoma: A 3.5-Year Follow-up.
Abstract Ewing's sarcoma is extremely rare in the foot. Below the knee amputation is indicated for most primary malignant bone tumors of the hindfoot, with few cases of successful limb salvage surgery having been reported. The use of 3-dimensional printed implants may successfully address reconstruction challenges after tumor resection. The authors present a case of a 30-year-old woman with a Ewing's sarcoma of the talus who underwent total talectomy and replacement of the entire talus with a custom-made 3-dimensional printed talar prosthesis. [Orthopedics. 201x; xx(x):xx-xx.]. PMID: 31136673 [PubMed - as sup...

Acute Carpal Tunnel Syndrome in Inpatients With Operative Distal Radius Fracture.
Abstract Acute carpal tunnel syndrome (CTS) may occur concomitantly with distal radius fracture (DRF) and is often managed with carpal tunnel release (CTR). Carpal tunnel syndrome may also develop postoperatively after DRF fixation. The authors sought to determine the rate of CTS with DRF, prophylactic CTR, and postoperative development of CTS. Furthermore, they also sought to identify predictors of these. The Nationwide Inpatient Sample database was queried (2002 to 2014) to identify adult inpatients undergoing surgical fixation of DRFs. They were segregated by the presence of CTS and further stratified by the ti...

Secondary Surgery Rates After Primary Fusion for Adolescent Idiopathic Scoliosis.
Abstract Instrumented spinal fusion is the gold standard treatment for surgical magnitude adolescent idiopathic scoliosis (AIS), with the goal being stable fusion without the need for additional procedures. The purpose of this study was to define the surgical return rates of AIS at a single center with respect to various instrumentation constructs used during initial spinal fusion. A retrospective chart review was performed of all patients with AIS who underwent instrumented fusion with a minimum of 2-year follow-up. Demographic information, implant type, and surgical approach for the primary surgery and all subse...

Figure-of-eight Reconstruction of the Sternoclavicular Joint: Outcomes of Sport and Work.
Abstract Instability of the sternoclavicular joint is a challenging condition given the proximity of neurovascular structures and minimal osseous constraint, and little is known regarding return to activity. A prospectively maintained institutional registry was retrospectively queried for all sternoclavicular joint reconstructions performed from 2005 to 2016. All included patients were asked to answer questions from a previously established survey to assess return to sport, work, and satisfaction following surgery. Ten patients (12 shoulders) were available for long-term follow-up (71.4%; range, 26-145 months). Th...

Rates of Perioperative Complications Among Patients Undergoing Orthopedic Trauma Surgery Despite Having Positive Results for Methamphetamine.
This study sought to determine the rate of cardiovascular complications in these patients. The authors reviewed the medical records of all patients between 2013 and 2018 who underwent orthopedic trauma surgery at two level I trauma centers in the setting of a methamphetamine-positive urine toxicology screening prior to surgery. Information on demographics, injury, type of surgical intervention, and incidence of perioperative cardiovascular and overall medical complications prior to discharge was recorded. Ninety-four patients were included in the study (mean age, 44 years; range, 16-78 years). Twenty-six (28%) patients had...

Failure of Fixation With Nickel-Titanium Staples in First Metatarsophalangeal Arthrodesis With Hallux Valgus Deformity.
Abstract First metatarsophalangeal (MTP) joint arthrodesis is a treatment option for patients with arthritic hallux valgus (HV). Nickel-titanium staples allow continuous compression throughout the fusion site and have been shown to achieve successful union in many procedures. However, their efficacy has not been tested in patients with underlying HV deformity. Three cases of severe HV deformity that underwent first MTP arthrodesis with 2 nickel-titanium staples placed 60° from each other and had failure are reported. The authors believe this construct does not provide adequate rotational control for first MTP ...
