| 1 | A comparative analysis of distal locked and unlocked long proximal femoral nail antirotation (PFNA-II) in the fixation of stable intertrochanteric fractures显示文摘Purpose:Long proximal femoral nail anti-rotation (PFNA-II) is a preferred implant in recent years for fixation of pertrochanteric fractures,especially in osteoporotic patients.The purpose of this study is to prospectively investigate the effect of distal locking in long PFNA-II fixation of stable intertrochanteric fractures.Methods:A total of 58 patients with isolated stable intertrochanteric fractures and treated in our hospital during the study period of 2017–2019 by distal locked or unlocked long PFNA-II fixation were included in this study.Patients who had multiple injuries or open fractures were excluded.There were 40 female and 18 male patients,with 33 affecting the left side and 25 the right side.Of them,31 belonged to the distal locked group (group A) and 27 to the unlocked group (group B).Surgical procedures and implants used in both groups were similar except for the distal locking of the nails.General data (age,gender,fracture side,etc.) showed no significant difference between two groups (allp > 0.05).The intraoperative parameters like operative time,radiation exposure and follow-up parameters like functional and radiological outcomes were recorded and compared.Statistical tests like the independent samplest-test Fischer’’s exact and Chi-square test were used to analyze association.Results:The distribution of the fractures according to AO/OTA classification and 31A1.2 type of intertrochanteric fractures were most common in our study.All the included fractures united and the average functional outcome in both groups were good and comparable at the end of one year.The operative time (mL,107.1 ± 12.6vs.77.0 ± 12.0,p < 0.001) and radiation exposure (s,78.6 ± 11.0vs.40.3 ± 9.3,p < 0.001) were significantly less among the patients in group B.Fracture consolidation,three months after the operative procedures,was seen in a significantly greater proportion of patients in group B (92.6%vs.67.7%,p = 0.025).Hardware irritation because of distal locking bolt was exclusively seen in group A,however this was not statistically significant (p = 0.241).Conclusion:We conclude that,in fixation of stable intertrochanteric fractures by long PFNA-II nail,distal locking not only increases the operative time and radiation exposure but also delays the fracture consolidation and increases the chances of hardware irritation,and hence is not required. | Atmananda Hegde Vikrant Khanna Prajwal Mane Chethan Shetty Nitin Joseph | 2023 | Chinese Journal of Traumatology2023，26，2： | 1 |
| 2 | Preoperative estimation of humerus intramedullary nail length using clinical landmarks显示文摘Purpose:Intramedullary interlocking nailing is one of the accepted methods of treating humerus diaphyseal fractures.Appropriate nail length and diameter are of paramount importance to achieve a stable fracture fixation.Estimating the nail length can be as challenging in certain cases as it is important.This study aims to provide an easy-to-use formula utilizing clinical measurements from contra lateral arm to accurately estimate humeral nail length.Methods:This descriptive cross-sectional study was conducted at 3 tertiary care hospitals in Mangalore,India.Patients above the age of 18 years coming to the outpatient department with elbow,shoulder or arm complaints requiring radiological investigation from July 2021 to July 2022 were included.Patients with fractures or dislocations of upper limbs,malunited or non-united fractures of upper limbs,congenital or developmental deformities and patients with open growth plates were excluded.Patients'variables(like age and gender),radiological humerus length and contralateral arm clinical measurements were recorded.An independent samples t-test was used for univariate analysis,and linear regression analysis was done to estimate the desired nail length using the clinical measurement of the humerus(cm)in both genders separately.The significance level was set at p<0.05.Results:Our study included 204 participants of which 108 were male and 96 were female.The formula for predicting humeral nail length in males is(-2.029)+(0.883×clinical measurement).The formula for females is 1.862+(0.741×clinical measurement).A simplified formula to determine humeral nail length is 0.9 clinical length-2 cm(in males)and 0.7×clinical length+2 cm(in females).Conclusion:To improve the stability of fixation with intramedullary nails it is imperative to select the appropriate nail length.There have been studies that devised reliable methods of determining nail lengths in the tibia and femur using preoperative clinical measurements.A similar clinical method of determining humeral nail length is lacking in the literature.Our study was able to correlate radiological lengths of the humerus medullary canal with clinical measurements performed using anatomical landmarks to arrive at a formula.This allows for a reliable and easy nail length determination preoperatively. | Atmananda S.Hegde Chethan B.Shetty Nitin Joseph Prajwal Mane Samarth Thakkar | 2023 | Chinese Journal of Traumatology2023，26，5： | 0 |
