The proximal femoral nail PFN is an osteosynthetic implant designed to treat proximal femoral fractures in the trochanter area with a closed intramedullary fixation method. Similar to the gamma nail the proximal femoral nail consists of a funnel-shaped intramedullary nail with slight bending to reflect proximal femoral diaphyseal trochanteric morphology. There are small holes at the distal end of the nail for locking screws 1. The proximal femoral nail comes also in different lengths with a version reaching caudally up to the distal femoral metaphysis. Longer nails are designed to treat low and extended subtrochanteric or combined trochanteric and femoral shaft fractures.

Intertrochanteric fracture is one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma like simple falls. Dynamic Hip Screw DHS is still considered the gold standard for treating intertrochanteric fractures by many. Intraoperative complications were noted. Functional outcome was assessed using Harris Hip Score and radiological findings were compared at 3, 6, and 12 months postoperatively. The average age of the patients was 60 years. In our series we found that patients with DHS had increased intraoperative blood loss ml , longer duration of surgery min , and required longer time for mobilization while patients who underwent PFN had lower intraoperative blood loss 73ml , shorter duration of surgery 91min , and allowed early mobilization. The average limb shortening in DHS group was 9. The patients treated with PFN started early ambulation as they had better Harris Hip Score in the early post-op period. At the end of 12th month, there was not much difference in the functional outcome between the two groups. PFN is better than DHS in type II intertrochanteric fractures in terms of decreased blood loss, reduced duration of surgery, early weight bearing and mobilization, reduced hospital stay, decreased risk of infection and decreased complications.

The Author ensures that the research has been conducted responsibly and ethically with adherence to all relevant regulations. Submission: February 18, ; Published: March 07, DOI: Background: Proximal femoral fractures are one of the most common fractures of the hip especially in the elderly with osteoporotic bones, usually due to low-energy trauma and in young adults due to high velocity trauma. The incidence of these fractures is rising because of increasing number of senior citizens with osteoporosis. The problems associated with proximal femoral fractures are due to substantial morbidity and mortality, malunion, implant failure and associated medical conditions. Therefore, this has led to the development of intramedullary devices in the management of proximal femoral fractures. Objective: To analyse the efficacy and functional outcome of proximal femoral nail in proximal femoral fractures. Materials and methods: A prospective cohort study with adult patients with proximal femoral fractures were treated with proximal femoral nailing in JJM Medical College, Davangere between to All the cases were followed at regular intervals as per our study protocol.

The original PFN allowed fracture stabilization with a load bearing sliding screw and with an additional hip pin for rotational stability of the head-neck fragment. This is achieved by compaction of the cancellous bone around the surface of the PFNA blade and results in an excellent fit between the blade and generally osteoporotic bone. Current clinical experience proves that the overall complication rate, especially the cut out rate, is low. To the existing nails more lengths have been added to — mm in 20 mm increments for both left and right nails in Ti-6Al-7Nb TAN and stainless steel. Those additional lengths have received AO TC approval in The proximal diameter is 17 mm; the distal diameter varies between 9, 10, 12, and 14 mm. All nails made out of steel come with flutes. The nails out of TAN have flutes for the versions with 12 and 14 mm diameter, the 9 and 10 mm ones are without flutes. Several components of the PFNA system have been improved to enable intraoperative compression, and facilitate insertion and cleaning. The design has been changed to allow intraoperative compression and to improve the strength of the blade also with respect to implant removal.

New method to remove a broken guide pin in the hip joint. Standard pre-operative planning was done. At 7 months, patient showed clinico-radiological signs of union. Fixation of intertrochanteric hip fractures: gamma nail versus dynamic hip screw: A randomized, prospective study. Patients were operated on fracture table with closed or minimal open reduction to create a mechanically stable fracture-bridging osteosynthesis using PFN. Immediate post-operative radiograph of the patient revealed relatively unstable fracture fixation because of loss of antero-medial buttress, superior placement of hip screws, almost same level of screw tips of both lag and derotation screw Figure 6b. Langenbecks Arch Surg. Pervez H, Parker MJ. Drilling with smaller sized reamer and proceeding with regular reamer will also help. The position of the femoral neck screw should ideally be in an inferior position from the AP view and centered position from the lateral view. Possible factors contributing for differential migration.

Although PFNA and TFN nailing systems have been successfully used in the past, several clinical issues for improvement have been identified by surgeons and engineers. Many of these issues have now been addressed and solved by implant and instrument design changes incorporated into the new TFNA nailing system.

J Orthop Trauma. Trochanteric fractures are one of the commonest fractures in aging population. She was initially managed with a upper tibial pin traction for two weeks and then later fixed with condylar blade plate fixation with bone grafting and antibiotic beads insertion near the fracture site [ Figure 6 ]. We had 3 such complications. Fractures less than 2 weeks of duration. Akt Traumatol. MOJ Orthop Rheumatol. The diameter was determined by measuring diameter of the femur at the level of isthmus on an AP X-ray. Article created:. Also note the varus mal-reduction long arrow. Copy Download. J Bone Joint Surg Am. Dynamic Hip Screw DHS is still considered the gold standard for treating intertrochanteric fractures by many. A new method of treatment of pertrochanteric fractures. Nevertheless PFN is technically demanding procedure, with appropriate technique; it gives excellent results even in unstable fracture patterns.
