386 Proximal Femoral Nail (PFN) Versus Dynamic Hip Screw (DHS) In Unstable Intertrochanteric Fractures of Femur -A Comparative Clinical Study

Abstract Introduction The goal of treatment of an intertrochanteric femoral fracture is restoration of patient's mobility as early as possible. The dynamic hip screw (DHS) has been used for several decades to treat these fractures. Proximal femoral nails (PFN) are reported to have an advantage in such fractures. This study aims at comparing the results of unstable intertrochanteric fractures femur treated with PFN and DHS. Method This was a prospective, randomized study which includes sixty patients. All patients were available for follow up with 30 patients in each group. The data about intraoperative blood loss, time to union, leg length shortening was collected. The functional outcome at the end of one year was evaluated using Harris Hip Score. Results Blood loss, duration of surgery, time to union and leg length shortening was significantly less in the patients treated with PFN (p < 0.05). The mean harris hip score for patients managed with PFN was significantly more than in DHS group, 12 months after surgery (p = 0.05). Conclusions PFN requires a smaller incision, lesser operative time, less blood loss and has improved functional results. In our opinion PFN may be a better fixation device for most of the unstable intertrochanteric femur fractures.

Background & Objective: Intertrochanteric femur fractures are becoming increasingly common as our population ages. Effective treatment strategies that result in high rates of union of these fractures and low rates of complication are important. This study was designed to evaluate the clinical outcome of intertrochanteric fracture treated with dynamic hip screw, among many other fixation techniques available to fix intertrochanteric fractures. Methods: This prospective interventional study was done in the Department of Orthopaedics & Traumatology Department of Dhaka Medical College Hospital, Dhaka between June 2013 to November 2014. A total of 30 patients having intertrochanteric femur fracture were treated with Dynamic Hip Screw (DHS) after doing all necessary investigations for anesthetic fitness. Regular follow up was done up to six months after each operation and was observed for fracture healing, stability, complications and functional outcome by the prescribed scoring system (Harris Hip Score). Result: Nearly one third (30.0%) of the patients belonged to 7th decade and male to female ratio was 1:1.3. According to Harris Hip Score, 13(44.82%) patients were rated as excellent, 9 (31.03%) good, 5(17.24%) fair and 2(6.89%) poor. Conclusion: Dynamic hip screw (DHS) is a reliable method of fixing the stable intertrochanteric femur fractures. The reliability and long-term effect of dynamic hip screw used to treat intertrochanteric fractures of unstable variety are unsatisfactory and not up to the mark.

Background: Hip bone fractures are the main cause of concern on a worldwide level. The main two operative techniques involve dynamic hip screw and proximal femoral nail technique. Aim: To compare the dynamic hip screw with proximal femoral nail technique in intertrochanteric femur fracture patients. Study design: Retrospective study Place and duration of study: Department of Orthopaedics, Khyber Teaching Hospital, Peshawar from 1-7-2019 to 30-12- 2021. Methodology: Seventy patients were enrolled and they were divided in two groups; Group 1 patients were operated with dynamic hip screw (DHS) while group 2 patients were operated by proximal femoral nail (PFN) technique. The detailed pre and post-operative clinical information including blood loss, incision size, Harris hip score and rate of complication was documented. Results: The mean age of patients was 58.62±6.71 year with more male patients than females. The Harris hip score of proximal femoral nail technique was better than distal hip screw. The incision length of distal hip screw cases was 7.61±0.89 in comparison to 4.72±0.73 in proximal femoral nail technique cases with a longer duration of surgery and inter-operative blood loss in case of distal hip screw cases. Conclusion: Proximal femoral nail technique is comparatively better than the distal hip screw procedure. Keywords: Proximal femoral nail technique, distal hip screw, Hip fracture

Background: Trochanteric fracture is the commonest fracture which accounts to 90 % of the fractures in patients over 50 years. The aim of the treatment is to prevent malunion and early mobilization with ambulation which is accomplished by dynamic hip screw and sliding plate. Minimal invasive technique has advantages of less blood loss, minimal soft tissue dissection, early mobilization and shorter hospital stay.The study was done to evaluate the amount of intraoperative blood loss, reduction of postoperative haemoglobin, requirement of postoperative analgesics and duration of postoperative hospital stay in the patients with stable intertrochanteric fracture treated with minimal invasive dynamic hip screw (MIDHS).Methods: Twenty five patients with stable intertrochanteric fractures were treated with minimal invasive Dynamic hip screw fixation. Average intra operative blood loss, reduction of postoperative haemoglobin, requirement of post-operative analgesics and total duration of postoperative hospital stay were evaluated. All the patients were followed up periodically at 6 weeks, 3 months, 6 months, 1 year. All the patients were evaluated radiologically in the follow up period. The functional assessment was done with Harris hip score.Results: Mean intraoperative blood loss was found to be 75 ml. The mean duration of surgery was found to be 44.3 minutes. All the patients were mobilized 24 hours of surgery with non-weight bearing walking with walker support. The average time for union was found to be 4 months. No complications like postoperative infection, malunion, coxa vara, limb length discrepancy were seen. The final functional Harris hip score was found to be excellent in 14, good in 4, fair in 2. Conclusions: MIDHS is a safe technique having advantages of less blood loss, minimal soft tissue dissection and shorter hospital stay, early rehabilitation in treating stable intertrochanteric fractures compared to conventional DHS.

Purpose: To evaluate intraoperative variables and postoperative outcomes of intertrochanteric fractures with vulnerable/broken lateral walls managed with short and long cephalomedullary nails. Materials & Methodology: Twenty prospective cases of patients treated with LCMN and twenty retrospective cases treated with SCMN were included in the study. Intraoperative variables compared were duration of surgery, blood loss during surgery, and surgeon's perception of surgery. Functional outcome was evaluated by Parker Palmer mobility score (PPMS), Harris hip score (HHS), and Short Form-12 at one year. Radiological assessment were done at six months/one year to look for progress of fracture union, change in neck-shaft angle, and any signs of implant failure. Results: Duration of surgery (p<0.001), blood loss during surgery (p=0.002), and surgeon's perception of surgery (p=0.002) were signicantly more in the LCMN group. The LCMN group had a better functional outcome. HHS for the LCMN group was 89.15±9.53, and for the SCMN group it was 81.53±13.21 (p=0.021). PPMS for LCMN group was 8.85± 0.67 and for the SCMN group was 7.53±1.807 (p=0.005). There were four implant failures in the LCMN group compared to none in the SCMN group (p=0.036). Conclusion: Both SCMN and LCMN are effective treatment modalities for unstable intertrochanteric fractures with vulnerable/broken lateral walls. In the absence of more extensive study and long-term follow-up, the superiority of one implant over the other cannot be recommended.

BACKGROUND Current management of Intertrochanteric (IT) fractures has evolved with the introduction of dynamic hip screw (DHS) and proximal femoral nail (PFN). The purpose of this study was to compare the functional outcomes between the DHS and PFN for IT fracture fixation. METHODS This study is a retrospective comparative analysis of 455 patients with IT fractures; DHS (292) and PFN (163), who were treated from June 2012 to June 2015. The patients were reviewed postoperatively for a minimum of 12 months to evaluate functional outcome using Salvati-Wilson score. Categorical data was present as absolute number or percentages, and parametric variables were presented as Mean ± SD, while non parametric data were presented as median. Statistical significance was defined as P < 0.05. RESULTS Intramedullary nails offer no advantage over extramedullary devices to treat IT fractures caused by low-energy trauma (AO 31 - A1). However, clinically significant outcomes were established for PFN group in terms of duration of surgery, x- ray exposure and SW Score for AO / OTA 31 - A2 and 31 - A3. Reoperations encountered for local pain due to implant prominence were significantly higher in the PFN group (4.90 % versus 1.02 %). Kaplan Meier survival probability of 69.3 % and 79.5 % predicted for DHS and PFN respectively, 3 years postoperatively. CONCLUSIONS Our conclusion reinforces indication for PFN in unstable IT fractures (31 - A2 and 31 - A3), owing to its better functional outcome and biomechanical properties. Functional outcomes for stable IT fracture (AO 31 - A1) were comparable between DHS and PFN, therefore final decision for implant choice depends on implant cost, surgeon’s preference for specific technique. However, understanding the morphology of proximal femur, peritrochanteric region is crucial to analyse the anatomical variations in Indian population which will provide the basis for intramedullary nail design modifications.

Background: Inter-trochanteric fracture of femur causes significant morbidity and mortality in elderly. Dynamic Hip Screw (DHS) fixation is the most effective and safe method of treatment. Conventional open technique (CDHS) is the popular and familiar one; however, minimal incision technique (MIDHS) has many advantages like: smaller incision, lesser dissection/blood loss, less requirement of transfusion, less painful, faster recovery etc. Objectives: To Compare CDHS and MIDHS technique of DHS fixation for inter-trochanteric fracture femur in terms of functional outcome, safety and associated complications (if any). Methods: Eligible patients presenting within study period were randomized into CDHS group (n= 33) and MIDHS group (n= 32). Success of randomization was tested by analyzing demographics, injury characteristics and pre-op. clinical data (p> 0.05). They were followed up at 2, 6, 12, 24 and 52 weeks post-op. for clinico-radiological and functional assessment. Results: The duration of surgery, lag screw positioning, post-operative hospital stay and surgical site infection were not significantly different between the groups. However, need for blood transfusion, length of incision and post-operative VAS score for pain were significantly lesser for MIDHS group than CDHS group (p< 0.05). Patients in MIDHS group started walking with aids significantly earlier in post-operative recovery period. The Harris Hip Score at final follow-up and grading of the results and surgical complications were not significantly different between the groups. Conclusion: The minimal incision technique had various immediate / short term advantages over conventional technique; like: minimal scar, minimal soft tissue dissection / less blood loss requiring less transfusion, lesser pain in post-operative period and ability to ambulate early.

Background: Intertrochanteric fractures are one of the commonly occurring injuries in elderly patients and are high among females and those with osteoporosis. They were treated with either dynamic hip screw (DHS) fixation or proximal femoral nailing (PFNA2) here at our institution. The study was conducted in order to find which method of surgical fixation has better functional outcome. Methods: Total 96 patients of intertrochanteric fractures admitted during the study period of November 2017 to April 2019 were included for the study. These patients were randomly divided into two groups; DHS was used as implant in group1 and PFNA2 in group 2. Postoperatively patients were followed up after 1 month, 3months and 6 months of the surgery and were assessed using Harris hip score.Results: Harris hip score was higher with PFNA2 group compared to DHS group in all follow-ups. In unstable fractures DHS group had poor outcome compared to PFNA2. Radiological union occurred in 27.1 % cases by 3 months and 72.9% cases by 6 months with DHS whereas 70.8% and 97.9% respectively with PFNA2. Conclusions: PFNA2 gives a better functional outcome when compared to DHS. Even though DHS gives good functional outcome in stable fractures it is not so in the case of unstable fractures. The radiological union also is faster with proximal femoral nailing. Hence in our opinion PFNA2 can be the better fixation device compared to DHS especially in unstable fractures.

Background: Proximal femur fractures are one of the commonest fracture encountered in orthopaedic trauma practice. Dynamic hip screw (DHS) is the gold standard procedure for treatment for stable intertrochanteric fractures, however problem arises with unstable fractures in maintenance of neck shaft angle and proper reduction. Here we are giving results of trochanteric fractures treated with proximal femoral locking compression plate (PFLCP) as compared with dynamic hip screw (DHS).Methods: This study was a prospective study. Two groups of trochanteric fractures of 25 patients operated with DHS and LCP were taken. Each patient was followed-up from July 2011 to October 2012 for minimum of 12 month or till the bony union. Every fracture was classified according to AO classification. Functional results will be assessed as per modified Harris hip evaluation score.Results: Among 25 patient treated with PFLCP, length discrepancy was .857 cm while that for DHS was 1.2 cm. The mean time of unaided walking with LCP Was 14.20 weeks while for DHS it was 16.20 weeks. The mean varus angulation for LCP 8 degree while for DHS 10.2 degree. In LCP in 1 case screw cut out from head and neck of femur while in DHS, same is seen in 2 cases and in addition loss of position of lag screw seen in 5 cases.one case was found with superficial infection in LCP while in case of DHS 3 cases with deep infection for that implant was removed and 6 cases were found with superficial infection.Conclusions: Proximal femoral locking plate (PFLCP) is simple, stable for fixation with fewer complications, and is an effective method for unstable intertrochanteric fractures. Comparing with DHS group, the locking plate has shorter operative time, fewer blood loss and drainage.

Background: The trochanteric fractures are one of the commonest fractures in elderly population. Incidence of these fractures is increasing due to better life expectancy, growing number of population, industrialization and the road traffic accidents. Variety of implants are available but still there is no consensus for single implant.Methods: A prospective randomized control study was conducted on total 60 patients of intertrochanteric fractures which were randomized into 2 groups of 30 each, treated with dynamic hip screw (DHS) and proximal femoral nail (PFN). All the patients were followed up for a maximum of 6 months. Outcomes were reviewed and compared such as mode of injury, complications, functional and radiological outcomes.Results: There was no significant difference between two groups of patients as regards to mean age and sex. The mode of injury by slip and fall was main cause. The most common type of fracture as per AO-orthopaedic trauma association (OTA) classification was 31-A2 (65%) and 31-A3 (5%) being the least common type. Mean surgical time of DHS group and PFN group was 125.17 minutes and 89.93 minutes respectively. Mean blood loss in DHS group and PFN group was 251.67 ml and 158.67 ml respectively. Mean radiological union time of fracture in DHS group and PFN group was 12.3 and 9.5weeks respectively. Mean Harris hip score at six month in DHS group and PFN group was 80.77 and 85.47 respectively.Conclusions: We conclude that though both the implants can achieve comparable union rates but PFN are better than DHS as of better Harris hip score, shorter surgical time and less intra operative blood loss.
