Femoral fractures can be common in nonambulatory patients with myopathies because they present with notable osteoporosis. From the orthopaedic perspective, this can be complicated by a pre-existing knee flexion contracture and small femoral shaft size. The goals of treatment are to reduce external immobilization, maximize comfort for transfers, prevent functional loss, and preclude refracture. The purpose of our work is to describe the anesthetic and orthopaedic considerations in treating a bed-bound adult patient with nemaline dystrophy and a midshaft femur fracture. The authors have obtained the patient's informed written consent for print and electronic publication of the case report. Copyright © 2019 The Authors.

CT and MR arthrography are necessary for preoperative imaging and assessment of glenoid bone loss. Patient expectations in conjunction with appropriate preoperative imaging are critical for surgical planning. Arthroscopic shoulder stabilization is often sufficient in most cases where glenoid bone loss is minimal, with recurrent dislocation rates close to 4% in the literature. Open stabilization procedures are generally indicated in patients with greater than 20% glenoid bone loss. Copyright © 2019 The Authors.

A standardized reduced opioid prescription protocol for TJA was initiated at our institution, which we hypothesized would lead to a reduction in opioid consumption compared with patients who had surgery before initiation of the new protocol. Methods We evaluated 97 consecutive opioid-naive patients undergoing primary total knee arthroplasty (TKA) and total hip arthroplasty (THA) using a standardized opioid prescription protocol (standardized group). A control subject group consisted of 99 patients undergoing TKA and THA just before the adaptation of the standardized prescribing protocol (historic group). Postoperatively, patients brought their remaining pain medication to their 1-month follow-up visit. The number of pills consumed was counted and converted into oral morphine equivalents (OME). Current pain level and the need for pain medication refill was assessed.

Summary Mycobacterium phlei is a rapidly growing nontuberculous osteomyelitis which is typically nonpathogenic with only four reported cases of human infection. Diagnosing infections related to nontuberculous mycobacteria (NTM) is difficult and can often be delayed as conventional microbiologic tests are inadequate. Currently, there are no consensus guidelines concerning the treatment of vertebral osteomyelitis caused by NTM. 4-MU compound library inhibitor A 45-year-old man presented with chronic back pain and bilateral lower extremity radicular symptoms status-post lumbar fusion with previous deep infection. CT scan demonstrated incomplete union after fusion. He underwent irrigation and débridement on March 15, 2016, with tissue culture and biopsy. Given negative cultures and completion of a 6-week course of intravenous antibiotics, on May 3, 2016, he went for implant removal and repeat instrumentation. During the same hospitalization, deep spinal fluid acid-fast bacilli culture from March 15, 2016, came back positive at 8 weeks, identified as Mycobaterium phlei. He was started on an empiric 4-drug regimen for NTM which he continued for 12 months. There has been no recurrence of infection to date. Discussion This case serves as the first description of M. phlei osteomyelitis of the spine and as a reminder that proper diagnosis of infectious etiologies is necessary for adequate treatment.

Previous studies have identified the risks associated with doing a TKA in an individual with an increased body mass index. We now present data identifying the same risks in individuals who have undergone bariatric surgery before submitting to TKA. Questions/Purposes (1) Has the bariatric surgery improved the risk profile for the subsequent TKA? (2) Does the type of bariatric procedure matter? Method A retrospective cohort study was conducted of patients who underwent bariatric surgery followed by TKA using Medicare hospital claims data. A study was undertaken using the Current Procedure Terminology codes and International Classification of Diseases-9 and International Classification of Diseases-10 for bariatric surgery. These identified entries were then cross-referenced to individuals who later underwent TKA, ide should be cautious in withholding care for patients with morbid obesity. Copyright © 2019 The Authors.

Given its location and variable course, the IPNB is suspected to be at risk of injury with commonly used incisions around the knee. Nerve injury may lead to painful neuroma formation. To our knowledge, no study has evaluated the incidence at which the IPNB is encountered during the anterior approach incision for a routine total knee arthroplasty (TKA). The purpose of this study was to see whether the general joint arthroplasty surgeon can identify and examine the location of the IPNB encountered during primary TKA and to determine whether these branches would be transected during a standard medial arthrotomy. Methods Seventy-three patients (76 knees) underwent primary TKA using a standard midline approach with a medial parapatellar arthrotomy. The IPNB was identified, and the distance was measured from the inferior pole of the patella to the point where the nerve crossed the medial border of the patellar tendon.
