Background: Subtrochanteric fractures are among the common fractures experienced in the current orthopaedic practice. Selection of implant still remains using the surgeon. The pros and cons from the Gamma nail happen to be well-established in a number of studies done previously, usually by evaluating the outcomes using the Dynamic hip screw (DHS). This research handles the comparison of Proximal femoral nailing (PFN) versus Dynamic hip screw (DHS) in management of subtrochanteric fractures.
Methods: This research was conducted in M. S. Ramaiah Hospitals from October 2007 to August 2009. During this time period 50 installments of adult patients with subtrochanteric fractures of femur were selected based on the inclusion criteria and classified based on Seinsheimer’s classification.
Results: We discovered that PFN was better than DHS in lots of ways for example reduced intra-operative bloodstream loss, lesser operative time, reduced radiation exposure, less quantity of limb shortening, reduced stay in hospital, lesser infection rates and early mobilization.
Conclusion: Nailing has the benefit of supplying rotational in addition to axial stability in the event of subtrochantric fractures allowing a quicker postoperative restoration of walking ability, in comparison with the dynamic hip screw.
Key Phrases: Subtrochanteric fractures Proximal Femoral Nailing Dynamic Hip screw, Reverse oblique subtrochanteric fractures.
Subtrochanteric fractures are among the common fractures experienced in the current orthopaedic practice. The incidence of subtrochanteric femoral fractures has elevated considerably during recent decades, which inclination will most likely continue soon because of the considerable rise in the existence expectancy resulting in an growing geriatric population. Many treatments can be found. The aim of treating these fractures is stable fixation, which enables early mobilisation from the patient. The pros and cons from the original style of the Gamma nail happen to be well-established in a number of studies done previously, usually by evaluating the outcomes using the dynamic hip screw (DHS). Within this context there’s insufficient data available a good alternative, the proximal femoral nail (PFN), and it is merits in the treating of subtrochanteric fractures. The current study ended to check the pros and cons of proximal femoral nail over dynamic hip screw among patients with subtrochanteric fracture.
Aims and Objectives
The primary purpose of this dissertation ended up being to:
I)Study the different sorts of subtrochanteric fractures.
ii)Read the concepts and control over subtrochanteric fractures with proximal femoral nailing and DHS.
iii)To critically evaluate both groups for
1.Intra-operative bloodstream loss, time period of surgery and intra-operative radiation exposure.
2.Duration in the day’s surgery to mobilization.
3.Infection rates.
4.Time period of remain at hospital.
5.Implant failure rates.
6.Union rates.
7.Go back to normal function.
8.Residual disability or deformity.
iv)Assessment of results according to subjective parameters, objective parameters and radiological findings.
Within this study, an effort has been created to examine the literature and compare our results along with other studies.
It was a potential randomized study conducted in M. S. Ramaiah Hospitals from October 2007 to August 2009. During this time period 50 installments of adult patients with subtrochanteric fractures of femur were selected based on the inclusion criteria. Alternate patients who satisfied the inclusion and exclusion criteria went through PFN and DHS correspondingly.

proximal femoral nail or Dynamic hip screw.
d)No specific time period of illness.
a) Previous surgery from the proximal femur.
b) Pathologic fractures apart from brittle bones.
c)Ongoing chemotherapy or irradiation treatment because of malignancy.
d)Polytrauma.
e)Those who were not able to provide consent.
The fractures were classified based on Seinsheimer’s classification. Type IIIA constituted maximum number of instances (n=20) with 12 in PFN group and eight in DHS group adopted by Type IV (n=08) with 2 in PFN group and 6 in DHS group. Remainder of 22 patients belonged to Type IIA(n=02), Type IIB(n=05), Type IIC(n=05), Type IIIB(n=05) and kind V(n=05). There have been no Type I pattern of fractures within our study. From the 50 patients, 26 of these went through fixation with Proximal Femoral nailing and rest 24 of these were given DHS regardless of their fracture pattern. From the 50 patients, 48 patients were readily available for follow-up. Within our series maximum age was 96 many the least 18 years(mean age=62.36 years). Maximum patients were of the 60-eighty years age bracket(n=19). Males were 37 and some women 13. Right side was affected in 24 cases and left in 26 cases. The most typical mode of injuries within our series were trivial fall (n=35), Traffic Accidents (RTA) comprising 13 cases and adopted by fall from height by 50 percent cases. All patients were treated on elective basis. Surgery was performed typically of three days with a variety of 1-11 days. The typical time taken for DHS procedure was 124.58 minutes when compared with PFN that was 102.3 minutes.The typical time period of radiation exposure was 56.35 seconds for nailing when compared with 96.25 seconds for DHS procedure. The typical quantity of bloodstream loss was 208.7 ml for PFN procedure and 483.33 ml for DHS procedure. In PFN Series, Postero-Medial cortical defect was observed in 4 cases that iliac cancellous bone grafting ended whereas bone grafting was needed in 10 installments of DHS Series.
The intra-operative complications experienced during proximal femoral nailing are listed below:
1.Jamming from the nail within the proximal fragment while insertion was noted in a single situation, requiring progressive reaming from the proximal fragment and using a lesser diameter nail.
2.In ten cases we’d to complete ‘free hands technique’ for distal screw locking because of mismatch from the Jig and nail,
3.In a single situation, fixation from the fracture happened in varus angulation.
4.In a single situation, iatrogenic fracture from the lateral cortex from the proximal fragment was noted, that was minimally displaced. No intervention ended for your fracture. Standing and walking was delayed publish-operatively.
5.In six in our cases we’d to do open reduction, because of wide displacement from the fragments .
6.In a single situation, with delay in surgery of 11 days was noted because the patient wasn’t fit to become adopted for surgery. We’d difficulty in decrease in the fracture within this patient, therefore the fracture site needed to be opened up up for reduction. They were generally observed in Type IV. V fractures as well as in obese individuals. No intra-operative complications were experienced during DHS procedure. Within our DHS series, we’d a situation of wound infection in the operative site which needed intravenous antibiotics for 3 days. Wound healed without resorting to any more intervention. No publish-operative complications were observed in PFN series. The typical time taken for mobilization from the moment of surgery for PFN series was 1.five days as well as for DHS series was 2.12 days. The typical time period of stay in hospital following surgery was 7.9 days varying from 5-fourteen days within the PFN series and 12.04 days varying from 5-20 days within the DHS series. There wasn’t any mortality within this study. The typical time period of follow-up was 15 several weeks varying from 5 – 26 several weeks, which 2 patients were lost to follow-up, one out of DHS series along with other in PFN series. Both patients were lost throughout the second month of follow-up. In PFN series, from the 26 cases, 10 cases demonstrated union at 12 days, 7 cases demonstrated union at 14 days duration, 4 cases demonstrated union at 18 days duration. 4 installments of delayed union were seen. 2 installments of delayed union needed dynamization that have been adopted up till bony union, which required 7 several weeks and eight several weeks correspondingly. Two other cases needed bone grafting in the fracture site, which u . s . at 6 several weeks and seven several weeks correspondingly. One situation of breakage of implant in situ at 5 several weeks was observed. Patient had damaged the implant following a fall in your own home. It had been given implant removal and re-nailing with PFN and bone grafting. Fracture u . s . after 18 days of re-nailing. In DHS series, from the 24 cases, 8 cases demonstrated union at 12 days duration, 6 cases demonstrated union at 14 days duration, 3 cases demonstrated union at 18 days duration. 3 installments of delayed union were seen, that bone grafting in the fracture site ended at 8weeks, 10weeks and 12 days. Fracture subsequently u . s . after 10 days, 10 days and 14 days correspondingly from the moment of bone grafting. Three installments of breakage of implant in situ were observed at 12 days, 20 days and 25 days. A couple of that have been treated by implant removal and repeat DHS application with bone grafting. They u . s . after 14 days and 16 days correspondingly. Other situation was treated by implant removal and nailing with gamma nail and bone grafting, which u . s . after 20 days in the second surgery. Bony union was achieved in 24 from the 26 cases (92.3%) in PFN series when compared with 20 out 24 cases (83.33%) in DHS series. 69.33% from the cases had great results in PFN series when compared with 70.8% in DHS series.
Within our series we discovered that PFN was better than DHS in lots of ways for example reduced intra-operative bloodstream loss, lesser operative time, reduced radiation exposure, less quantity of shortening, reduced stay in hospital, lesser infection rates and early mobilization.
We’ve figured all reverse oblique fractures should be managed by PFN only as the likelihood of failure of fixation are extremely high with extra-medullary devices.
Nailing has the benefit of supplying rotational in addition to axial stability in the event of sub-trochanteric fractures allowing a quicker postoperative restoration of walking ability, in comparison with the DHS. Their nails are load-discussing implants, whereas extra-medullary products are load-bearing. Proximal femoral nailing results in a shorter lever arm, which means a lesser bending moment along with a decreased rate of mechanical failure 52 .
