Background. Percutaneous endoscopic interlaminar discectomy (PEID) has achieved favorable effects in the treatment of lumbar disc herniation (LDH), as a new surgical procedure. With its wide range of applications, a series of complications related to the operation has gradually emerged. Objective. To describe the type, incidence and characteristics of the complications following PEID and to explore preventative and treatment measures. Study Design. Retrospective, observational study. Setting. A spine center affiliated with a large general hospital. Method. In total, 479 cases of patients with LDH received PEID, which was performed by an experienced spine surgeon between January 2010 and April 2013. Data concerning the complications were recorded. Result. All of the 479 cases successfully received the procedure. A total of 482 procedures were completed. The mean follow-up time was 44.3 months, ranging from 24 to 60 months. The average patient age was 47.8 years, ranging from 16 to 76 years. There were 29 (6.0%) related complications that emerged, including 3 cases (0.6%) of fragment omission, and the symptoms gradually eased following 3–6 weeks of conservative treatment; 2 cases (0.4%) of nerve root injury, and the patients recovered well following 1–3 months of taking neurotrophic drugs and functional exercise; 15 cases (3.1%) of
Background. Total hip arthroplasty (THA) has been and continues to be the gold standard for treatment of end-stage osteoarthritis. With each year, implant characteristics are evolving to increase patient-reported outcomes and decrease complications. Purpose: to report minimum 2-year outcomes and complications in patients who underwent robotic-arm assisted THA using Corin versus Stryker-type implants. Methods. Data were prospectively collected on patients who underwent THA with Corin-type implants (both cup and stem) and THA using Stryker implants between June 2011 and July 2016. A 1:1 propensity match was performed using the following 5 covariates: age, body mass index, gender, Charlson score and smoking status. Surgical outcomes were assessed at minimum 2-year follow-up using the Forgotten Joint Score (FJS), Harris Hip Score (HHS), Veterans RAND 12-item physical and mental health survey, Short Form 12 physical and mental health survey, Visual Analog Score (VAS), and patient satisfaction. The exclusion criteria were previous hip condition/surgery, workers compensation, or were unwilling. Results. Of the eligible 774 cases, 645 patients (83.3%) had minimum 2-year follow-up and met inclusion and exclusion criteria. Of the 645 patients, 323 had Corin implants, and 155 had Stryker implants. The 1:1 propensity match successfully yielded 290 patients (145 per implant group) which had a minimum 2-year follow-up at a mean 38.3 months (range, 24.1–65.3 months). Average age was 59.9 (range, 34.92–79.89 Stryker group, 30.65–75.92 Corin group) for each group and average BMI were 30.0 (range, 19.05–49.33) kg/m. 2. for the Stryker group and 29.77 (range, 20.15–55.37) kg/m. 2. for the Corin group. FJS (P=0.0388) and patient satisfaction (P=0.0019) were significantly higher in the Stryker implant group than the Corin implant group. There were nine cases of postoperative thigh numbness or
Femoral nerve block is a reliable and effective method of providing anaesthesia and analgesia in the peri-operative period but there remains a small but serious risk of neurological complication. We aimed to determine incidence and outcome of neurological complications following femoral nerve block in patients who had major knee surgery. During the period January 2003 to August 2008, medical records of all patients undergoing knee surgery by Dr Myles Coolican and Dr David Parker, who had been administered femoral block for peri-operative analgesia, were evaluated. Patients with a neurological complication were invited take part in the study. A detailed physical examination including sensory responses, motor response and reflexes in both limbs was performed by an independent orthopaedic surgeon. Subjective outcome and pain specific questionnaires as well as clinical measurements were also collected. Out of 1393 patients administered with femoral nerve block anaesthesia during this period, 28 subjects (M:F= 5:23) were identified on the basis of persistent symptoms (more than three months) of femoral nerve dysfunction. All the patients had sensory dysfunction in the autonomous zone of femoral nerve sensory distribution. The incidence of neurological complications was 2.01%. One patient was deceased of unrelated causes and five patients declined to participate in the study. 14 patients out of the 22 have been examined so far. Nine cases had a one shot nerve block and five had continuous peripheral nerve block catheter. Areas of hypoesthesia/anaesthesia involving femoral nerve distribution occurred in 7 subjects and hyperaesthesia/
Introduction. Ulnar nerve entrapment is the second most common nerve entrapment syndrome of the upper extremity. Despite this, only a few studies have assessed the outcome of ulnar nerve decompression. The objectives of the study were to review the pre-operative symptoms, nerve conduction studies, the co-morbidities, operative procedures undertaken and the post-operative outcomes; and investigate and ascertain prognostic factors particularly in cases of persistence of symptoms after the surgery. Methods. We reviewed the case notes of ulnar nerve decompressions surgery performed over a period of six year period. A structured proforma was created to document the demographics, patient complaints, method of decompression, per-operative findings and symptom status at the last follow up. Outcome grading was recorded as completely relieved, improved, unchanged or worse. Analysis of data was carried out using the SPSS software (Version 16.0; Illinois). The significance level was set at 5%. Results. 136 ulnar nerve decompressions formed the study group. Minimum follow-up was three months. Numbness and
