RESUMEN
This study aimed to demonstrate that measuring the medial gap before bone resection during total knee arthroplasty (TKA) provides an optimum gap adjustment in varus knees. In this study, patients were separated into two groups. Group 1 included patients whose medial joint gap was measured before bone resection and Group 2 included patients who underwent conventional technique without measuring. The medial joint gap was measured with a custom-made gap measuring device up to the point that the knee was corrected and aligned along its mechanical axis. Medial joint gap distances, distal medial femoral bone cut thicknesses, amounts of tibial resection calculated; gap internal distances measured after cutting and the thicknesses of the trial inserts were recorded. A comparison was made between the groups concerning the number of patients requiring an additional tibial bone cut and the distribution of insert thicknesses. Extra tibial bone resections were performed in two (5.7%) patients in Group 1 and 10 (28.6%) patients in Group 2. In Group 1, where the medial joint gap was measured, the need for an additional bone resection was statistically less (p=0.018). In comparing the distribution of insert size by group, the number of patients on whom an 8 mm insert had been used was significantly greater in Group 1 (p=0.024). The findings obtained in this study suggest that measuring the medial joint gap before bone resection in total knee arthroplasty may prevent repeated bone recutting and additional bone resections.

BACKGROUND: In this study, it was aimed to determine whether median nerve epineurectomy is beneficial in the surgical management of carpal tunnel syndrome (CTS). MATERIALS AND METHODS: The study enrolled 72 patients including 34 patients without epineurectomy (Group A) and 38 patients with epineurectomy (Group B). Surgery was performed in patients with severe electrodiagnostic CTS findings, CTS duration >1 year and flattening along with hypervascularization in median nerve. All patients were assessed by visual analog scale, two-point discrimination test as well as subjective and objective findings at baseline and on the months 1, 3, and 6 after surgery. RESULTS: The mean age was 58.3 years (42-75 years) in 38 patients who underwent an epineurectomy, whereas it was 61.5 years (41-82 years) in 34 patients who did not have an epineurectomy. The groups were similar with regard to age, gender, duration of symptoms, and preoperative physical findings. Mean visual analog scale (VAS) scores were 1.7 in Group A and 1.8 in Group B. Again, these differences were not significant, on physical examination, the average two-point discrimination in the distribution of the median nerve was 4.9 mm (range: 3-11 mm) in Group A and 5.3 mm (range: 3-10 mm) in Group B. In postoperative evaluations, there was a better improvement in visual analog scale scores, two-point discrimination test and subjective symptoms including dysesthesia, pain and nocturnal pain within first 3 months; however, there was no marked difference in objective and subjective findings on the 6th month. No complication or recurrence was observed. CONCLUSION: We believe that median nerve epineurectomy is unnecessary in the surgical management of primary CTS since it has no influence on the midterm outcomes.

AIM: This study aimed to understand nursing practice environment characteristics in Istanbul-area hospitals in Turkey, the relationship between these characteristics, nurse burnout levels and nurses' intentions to leave work. BACKGROUND: A well-known relationship exists in many countries between nursing practice environments and nurse burnout and intention to leave work. However, little is known about the relationship between practice environment characteristics and nursing outcomes in Turkey. METHODS: This cross-sectional study was conducted among 2592 nurses in 20 Ministry of Health and 29 private hospitals in Istanbul, Turkey. A demographic questionnaire, Practice Environment Scale of the Nursing Work Index and Maslach Burnout Inventory were used for data collection. RESULTS: Almost half of nurses suffered from high-level burnout related to emotional exhaustion and personal accomplishment, and one-third reported depersonalization and the intent to leave their jobs within a year. A poor nursing practice environment was the leading factor, increasing nurses' burnout levels in all subdimensions. Burnout related to emotional exhaustion, personal accomplishment and poor practice environment increased intention to leave. Permanent positions decreased intention. DISCUSSION: There was a relationship between poor practice environments and nursing outcomes in Turkey. LIMITATIONS: The use of a survey data collection method is a potential study limitation. Quantitative and qualitative methods could be combined to obtain more detailed objective data about nursing practice environments. CONCLUSION: Poor practice environments, high-level burnout and intention to leave work are significant problems in Istanbul, Turkey. Favourable practice environments and job security should be provided to improve nursing outcomes. IMPLICATIONS FOR NURSING POLICY: Policymakers and nurse managers should be aware of any negative issues regarding nursing practice environments and job security to improve nursing outcomes.
