A novel scoring system incorporating sarcopenia to predict postoperative survival in spinal metastasis.

BACKGROUND CONTEXT: As the prevalence of spinal metastasis rises, methods to predict survival will become increasingly important for clinical decision-making. Sarcopenia may be used to predict survival in these patients. PURPOSE: The purpose of this study to develop a prediction model incorporating sarcopenia for postoperative survival in patients with spinal metastasis. DESIGN: Retrospective cohort study. PATIENT SAMPLE: This study included 200 patients who underwent operative intervention for spinal metastasis in our institution, a tertiary, academic spine center. OUTCOME MEASURES: The primary outcome measure was 1-year postoperative survival. The secondary outcome measures were 3-month and 6-month postoperative survival. METHODS: Clinicopathological and survivorship data was collated. Sarcopenia was defined using the L3 Psoas/Vertebral Body Ratio on cross-sectional CT. Independent predictors of postoperative survival were assessed by multiple logistic regression. RESULTS: Overall 1-year postoperative survival was 50%. L3/Psoas ratio ≥1.5 (OR 6.2), albumin ≥35g/l (OR 3.0) and primary tumor type were found to be independent predictors of 3 month, 6 month and 1 year postoperative survival on multivariable analysis. Age at surgery, ambulatory status and mode of presentation were not independent predictors of survival. Variables were used to generate a new scoring system, ProgMets, to predict postoperative survival. The ProgMets system had greater correlation and higher area under the curve (AUC, 0.80) for 1-year survival than other scoring systems. CONCLUSIONS: This is the first model to incorporate sarcopenia to predict survival in spinal metastasis patients and has good prediction of survival compared to previous models. This tool may be increasingly useful for informed decision making for patients and surgeons.

The Not-So-Merry-Go-Round: Traumatic Inferior-Anterior Hip Dislocation in a 9-Year-Old.

Merry-go-rounds are not as innocuous as they may seem. Pediatric hip anterior-inferior dislocations are very rare and can be associated with low-energy trauma. Prompt recognition of pediatric hip dislocations is vital, and this should be treated as a time-sensitive orthopedic emergency. Closed reduction within 6 hours minimizes the risk of avascular necrosis (AVN). We present a case of a 9-year-old boy with an inferior-anterior hip dislocation following low energy trauma while playing on a merry-go-round. The patient was emergently brought to the theatre for closed reduction under general anesthesia within 6 hours. At his 12-month follow-up, he has a full range of motion without any pain.

Treatment of Pasteurella multocida Cervical Epidural Abscess.

A 51-year-old left-handed Caucasian female with no significant medical history presented with a two-week history of severe neck pain and bilateral upper limb weakness. Neurological examination revealed weakness and altered sensation in the C5-T1 distribution bilaterally, more severe on the left with Medical Research Council's scale (MRC scale) of muscle power grade 3/5 and 4/5 on the right with upper motor neuron signs. Short-TI Inversion Recovery (STIR) and T2 weighted MRI imaging revealed increased signal at the C6-7 disc representing discitis, as well an anterior epidural collection from C5 to C7, with associated cord compression. The patient underwent an emergency anterior cervical corpectomy of C6, drainage of the epidural purulent collection, and insertion of a cage and plate. Some tissue and pus samples were sent to the microbiology laboratory for analysis, and the organism Pasteurella multocida was identified on all samples. The patient clinically and biochemically improved with operative management and a prolonged course of intravenous ceftriaxone. A peripherally inserted central catheter (PICC) line was placed and the patient was discharged on eight weeks of intravenous ceftriaxone and ongoing physical therapy.

Retained Foreign Body in a Diabetic Patient's Hand.

BACKGROUND: Diabetic peripheral neuropathy puts patients at increased risk of acute injury by foreign bodies and also contributes to delayed presentation and diagnosis. CASE REPORT: We describe a 57-year-old patient with poorly controlled type 1 diabetes who presented with a three-week history of worsening swelling and erythema in the metacarpophalangeal joint of his left thumb. He denied any previous trauma or injury and was initially treated with intravenous antibiotics. Subsequent imaging revealed septic arthritis and osteomyelitis secondary to a retained foreign body, which was surgically removed in theatre. CONCLUSION: This is the first reported case of a retained foreign body in the hand of a diabetic patient, and demonstrates the importance of early radiological imaging of peripheral limb injuries in high-risk patients.

Vancomycin-Induced DRESS Syndrome: An Important Concern in Orthopedic Surgery.

DRESS (drug reaction with eosinophilia and systemic symptoms) is a potentially serious complication when prolonged courses of antibiotics are given to patients, with an average onset of 2-6 weeks after commencement. There is a high mortality rate (1-10%). We report the case of a 62-year-old male who developed DRESS after seven weeks of antibiotic treatment with vancomycin for a deep spinal metalwork infection. We describe the typical rash and biochemical results, including eosinophilia, as well as the systemic signs seen in this case. The criteria for diagnosis of DRESS, including the RegiSCAR scoring system and commonly affected systems (renal, cardiac, and hepatic), are detailed, and we also discuss evidence for steroid treatment and considerations important in the use of this.

Requesting spinal MRIs effectively from primary care referrals.

OBJECTIVE: To define if MRI scans can accurately be requested based on information provided in the primary care referral and, therefore, streamline the patient journey. The demand for outpatient spinal appointments significantly exceeds our services' ability to provide efficient, high-quality patient care. Currently, magnetic resonance imaging (MRI) of the spine is requested following first consultation. METHODS: During routine vetting of primary care referral letters, three consultant spinal surgeons recorded how likely they thought each patient would be to have an MRI scan. Following the first consultation with the spinal service, the notes of each patient were reviewed to see if an MRI was requested. We measured the positive predictive value (PPV), negative predictive value (NPV), sensitivity and specificity of ordering MRI scans based on primary care referral letters. RESULTS: 149 patients were included [101 females, 48 males, mean age 49 (16-87)]. There were 125 routine, 21 urgent, and 3 'urgent-suspected cancer' referrals. The PPV of ordering MRIs before first consultation was 84%, NPV was 56% with the sensitivity and specificity being 82 and 59%, respectively. Ordering MRIs during initial vetting could shorten the patient journey with potential socioeconomic benefits. CONCLUSIONS: MRI scans can be effectively ordered based on the information provided by the primary care referral letter. Requesting MRI scans early in the patient journey can save considerable time, improve care, and deliver cost savings. These slides can be retrieved under Electronic Supplementary Material.

Fracture clinic redesign: improving standards in patient care and interprofessional education.

INTRODUCTION: Current fracture clinic models, especially with the advent of reductions in junior doctors' hours, may limit outpatient trainee education and patient care. We have designed a new fracture clinic model, involving an initial consultant-led case review focused on patient management and trainee education. METHODS: Prospective outcomes for all new patients attending the redesigned fracture clinic over a 3-week period in 2010 (n = 240) were compared with a historical cohort from the same period in 2009 (n = 296). The primary outcome measure was the proportion of patients with direct consultant input. Secondary outcome measures included patient discharge rates, return rates, use of the nurse-led fracture clinic and the incidence of adverse event reporting. Trainees attending each clinic completed a five-point Likert questionnaire assessing the adequacy of education, support, staff morale and standards of patient care, before and after introduction of the clinic redesign. Using a separate Likert questionnaire, emergency room (ER) staff were evaluated to determine the impact of the new style clinic on their education, daily practice and interprofessional relations. Adverse events were gathered from the 'incident record 1' (IR1) reporting system. RESULTS: The percentage of cases given consultant input increased significantly from 33% in 2009 to 84% in 2010 (p <0.0001), while the proportion of patients requiring physical review by a consultant fell by 21% (p <0.0001). Return rates were reduced by 14% (p = 0.013) and use of the nurse-led fracture clinic improved by 10% (p = 0.0028). There was a median improvement in trainee perception of education from 2 (interquartile range 1.25-2.75) to 5 (4.25-5, p = 0.011), senior support from 2 (2-3) to 5 (4-5, p = 0.017) and patient care from 3 (3-4) to 5 (4-5, p = 0.015). ER staff found the new style clinic was educational, practice changing and improved interprofessional relations, but that it did not interfere with ER duties. The incidence of adverse incidents reported fell from 8 per year to 0 per year after the introduction of the new style clinic. CONCLUSIONS: Our model of fracture-clinic redesign has significantly enhanced consultant input into patient care without additional funding. In addition, we have demonstrated increased service efficiency and significant improvements in staff support, morale and education. In the face of current economic and training challenges, we recommend this new model as a tool that will enhance patient and trainee experience.

Efficacy of outpatient bilateral simultaneous hallux valgus surgery.

Bilateral simultaneous hallux valgus correction is traditionally performed as an inpatient procedure due to concerns regarding adequate postoperative analgesia and difficulty mobilizing. We prospectively evaluated 40 consecutive patients (80 feet) who underwent outpatient surgical correction of bilateral symptomatic hallux valgus. Patients underwent preoperative radiological and clinical assessment using pain and American Orthopaedic Foot & Ankle Society (AOFAS) hallux assessment scores. Patients underwent preoperative counseling and were assessed for medical suitability for outpatient surgery. They were instructed to have responsible adult caregivers available for 24 hours postoperatively, easy access to after-hours emergency medical care, and access to a telephone. Procedures were performed under general anesthesia with local anesthetic ankle block. Postoperatively, patients were discharged after assessment by medical, nursing, and physiotherapy staff with an oral analgesia regimen. Cast immobilization was not used. Patients were reviewed at 6 weeks and 3 months postoperatively with repeated clinical and radiological assessment. All patients were discharged home and none required inpatient ward admission. Post-discharge, no patient presented to the emergency department or their general practitioner as a consequence of poor pain control. At final follow-up assessment, mean AOFAS hallux scores had improved from 58.1 (range, 29-80) to 89.0 (range, 47-100) (P<.001). The mean hallux valgus angle improved from 33.2 degrees (range, 15 degrees -53 degrees) to 16.9 degrees (range, 3 degrees -39 degrees) and the intermetatarsal angle had improved from 13.2 degrees (range, 6 degrees -23 degrees) to 8.5 degrees (range, 4 degrees -15 degrees) (P<.001). Eighty-five percent of patients reported that they would recommend outpatient surgery. Bilateral hallux valgus surgery can be performed safely as an outpatient procedure in selected patients with acceptable levels of patient satisfaction.
