Total Hip Joint Replacement in a Patient with Colchicine-Resistant Familial Mediterranean Fever under Canakinumab Treatment.

Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever and serositis. Periodic febrile attack can be managed with biologic medication in colchicine-resistant FMF patients, however, no reports or guidelines exist regarding the postoperative management of elective joint surgery in these patients. Although it is not clear how FMF attacks are triggered, they may be precipitated by stress including anesthesia or surgery. This study reports the case of a 51-year-old FMF patient who received total hip replacement under canakinumab (a specific interleukin-1ß monoclonal antibody) treatment. He had highly active FMF, which was resistant to colchicine; however, his recurrent febrile attack with serositis was successfully controlled with canakinumab. Four months later from the start of canakinumab treatment, his hip osteoarthritis was required for total hip replacement (THR) because of the traumatic fracture. THR was successfully done and FMF attack was not occurred after this elective surgery. Discontinuation of canakinumab 3 weeks before surgery and resumption 6 weeks after led to favorable outcome without complications. This case addresses the differential management concerning stopping and restating of canakinumab in the perioperative setting in contrast to the other biologics such as tumor necrosis factor-α (TNF-α) or interleukin-6 (IL-6) blocking agents. This case report suggests that canakinumab may represent a safe and effective therapy for the colchicine-resistant FMF, even in the patients requiring THR therapy.

Clinical outcomes of lumbar diseases specific test in patients who undergo endoscopy-assisted tubular surgery with lumbar herniated nucleus pulposus: an analysis using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ).

PURPOSE: This study was to evaluate clinical outcomes using a patient-oriented test that scores health-related quality of life (HRQOL) for patients after minimally invasive surgery using microendoscopic discectomy (MED) for lumbar disc hernia. Few studies regarding MED in terms of disease-specific quality of life measures using Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) have been published. METHODS: Retrospective analysis of the surgical and clinical outcomes with regard to reducing pain and improving the functional status for 31 patients who underwent MED for lumbar disc hernia was conducted. These patients were evaluated at 3-year follow-up. The evaluations were based on a visual analogue scale (VAS), the Japanese Orthopaedic Association (JOA) scoring system, and the JOABPEQ, which is an objective, patient-oriented test that assesses HRQOL in patients with lumbar disorders. RESULTS: A low rate of improvement was seen only in mental health until 1 year, the low rate of improvement in mental health and was independently correlated with body mass index (BMI), pre-operative scores on the Brief Scale for Psychiatric problems in Orthopaedic Patients (BS-POP), and scores on the BS-POP at 12 months post-operatively. CONCLUSIONS: All categories of VAS, JOA scores, and all domains of JOABPEQ were significantly higher over 3 years than those obtained pre-operatively. But only mental health domain showed mild improvement until 1 year. Moreover, BMI showed a negative correlation with improvements in the mental health domain post-operatively. As patients may be mentally exhausted from lumbar disc herniation, pre-operative mental health may be improved by surgical treatment.

Recovery of paraplegia following postoperative epidural hematomas in lumbar canal stenosis surgery by closed kinetic chain (CKC) exercises: A case report.

RATIONALE: A postoperative spinal epidural hematoma (PSEH) is among the most devastating complications following spine and spinal cord surgery, and it should be considered before performing microendoscopic decompression as part of minimally invasive surgery, since early recovery is one of the advantages of this procedure. PATIENT CONCERNS: A 70-year-old woman with lumbar spinal stenosis at L4-5 underwent tubular surgery with the assistance of endoscopic laminectomy (MEL), but 2 days after the surgery, the patient noticed decreased lower limb sensation and power of the right leg, and she developed numbness from the level of L5 and weakness from the L4, 5 myotome distally. DIAGNOSES: An epidural hematoma at the L4-5 surgical site was found on magnetic resonance imaging of the lumbar spine and evacuated operatively. This rare complication appears to be the result of a PSEH. In the present case, complete neurological recovery was not achieved, despite rapid surgery. INTERVENTIONS: The patient's course and physical therapy, which focused on attitude maintenance practice and muscle-strengthening exercise of the closed kinetic change (CKC) type from the early stage of paraplegia, were specifically examined. OUTCOMES: The patient recovered complete motor function with attitude maintenance practice and muscle strengthening exercises after 3 months. CKC exercise in particular may contribute to improving caudal muscle weakness, including the L4, 5 innervated area (e.g., tibialis anterior [TA], extensor hallucis longus [EHL], flexor hallucis longus [FHL], gastrocnemius [GC], etc.). LESSONS: Prevention of PSEH is needed to not only avoid neurological deterioration, but also avoid delaying the patient's recovery. CKC exercise may contribute to improving the prolonged paralysis associated with a PSEH. Future studies should involve larger numbers of patients to evaluate the clinical features of PSEH and treatment by rehabilitation with more effective muscle exercises and stretches.
