Especially for unstable fractures or those with reverse obliquity (33.A3), it is our belief that there is no adequate evidence to support any deviation from the current practice, which is consistent with the use of a long statically locked nail. Synthes. All registration fields are required. 50. Gamma3 Long Nail is intended for fixation of stable and unstable femoral fractures occurring from the base of the femoral neck extending distally to a point approximately 10cm proximal to the intracondylar notch including fractures of the basilar neck, intertrochanteric fractures, peritrochanteric fractures, subtrochanteric fractures and femoral shaft fractures. Regardless, one must rule out a hip fracture, a pelvis fracture, a spine injury, spinal stenosis, trochanteric bursitis, muscle tears, and knee injuries. Hip fractures are often the result of a fall. 14. The load bearing of any intramedullary nailing is largely dependent on the fracture pattern and the achieved reduction.12,28 When cortical contact across the fracture site is achieved, a large portion of the compressive loads will be supported by the cortices; however, in the absence of cortical contact, the compressive and rotational loads are transmitted distally through the nail to the distal interlocking screws. The nail extends throughout the shaft, protecting the rest of the bone from future fracture. Mortality risk after hip fracture. Injury. 30. 2009;40:663–668. Kleweno C, Morgan J, Redshaw J, et al.. Short versus long cephalomedullary nails for the treatment of intertrochanteric hip fractures in patients older than 65 years. 2007;89:470–475. 2008;90:700–707. • Mean value of the failure load for the TRIGEN™ INTERTAN™ device was 1640 ± 56N compared to 1430 ± 60N for Gamma3™ • In 9 out of 10 comparisons, the TRIGEN INTERTAN device survived on average 51,000 ± 4,000 additional cycles more than Gamma3 2014;28:715–720. Gender differences in patients with hip fracture: a greater risk of morbidity and mortality in men. 2005;19:5–9. Fractures often cause severe pain, swelling, and inability to bear weight. No differences have been found between the two devices in stable fractures. Cochrane Database Syst Rev. Introduction. If the stem is not well fixed in the proximal femur, either type will fail quickly. 2012;98:85–89. De chirurg plaats een ronde pen (gamma-nagel) in het dijbeen. A long nail was chosen to “pro- 45. Injury. However, most systems lack reliability and, in general, intertrochanteric fractures can be divided into two categories: stable and unstable. J Orthop Trauma. 3. The proximal diameter of the nail is 15 mm and length is 18cm. The shaft and the distal end of these nails vary significantly as far as the radius of curvature, width, shape of the nail tip and also the number, location, and method of insertion/guidance of distal locking screws. Reamed Versus Unreamed Intertrochanteric Femur Fractures, Is It Time? The gamma nail consists of a large screw placed in the 28. Hip fracture. Summary In summary, the type of fracture determines the type of surgery. Displaced fractures in young patients are usually treated with pinning. J Orthop Trauma. Parker M, Johansen A. Arch Orthop Trauma Surg. AAOS annual meeting; March 19–23, 2013; Chicago, IL. Contact us or find a patient care location. Total joint replacement typically is performed on an active patient or one with preexisting arthritis. Future studies should include functional outcome parameters, radiological outcome, and patient-reported outcomes. 2007;15:97–106. They are less common than femoral neck and intertrochanteric fractures, accounting for approximately 5% to 15 % of hip fractures. 4 Normale heup Gamma-nail PFNA TFN De eerste 6-12 weken na de operatie moet de pen de kans krijgen om goed vast te groeien. The comparison of clinical end points between studies using nails of different generations, designs, and characteristics of the existing meta-analysis remains frustratingly inconclusive.13,15,57. A reliable predictor of post-operative lateral wall fracture in intertrochanteric fractures. Arch Osteoporos. When the tip-apex distance was greater than 45 mm, the screw cut-out rate increased to 60%. The use of long or even short cephalomedullary nails with and without distal interlocking fixation has been recommended for both stable and unstable intertrochanteric femoral fractures. Maqungo S, Horn A, Bernstein B, et al.. Distal Inter-locking screw Placement in the femur: free-hand versus Electromagnetic assisted technique (Sureshot). 12. Lindsey RW, Teal P, Probe RA, et al.. Rosemont (IL): American Academy of Orthopedic Surgeons; 1993. Most complications are treated with total hip arthroplasty. Cochrane Database Syst Rev. The absence of robust evidence extends also to the specific characteristics of the nails, as far as the 2 aspects of intramedullary fixation of intertrochanteric fractures that were the subject of this article. 8. Gamma and other cephalocondylic intramedullary nails versus extramedullary implants for extracapsular hip fractures in adults. Fractures with multiple pieces and fracture lines are termed ”comminuted”. The profunda femoris or superficial femoral artery can be at risk when a short nail is inserted,46 and, as Yang et al47 reported, for some patients presenting with intertrochanteric fractures, the superficial femoral artery is quite close (<10 mm) to the medial femur cortex, while the extremity is held at the usual position of closed reduction of intertrochanteric fractures (ie, internal rotation and adduction). Proximal Femoral Nail Antirotation™ (PFNA) Versus Gamma Nail 3™ (Gamma3) for Intramedullary Nailing of Unstable Trochanteric Fractures (PROGAINT-ES) The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. A short or a long nail would be sufficient in this case. 22. Alongside of having distal locking screws acting as stress risers that cause subsequent implant breakage, distal interlocking has been associated with soft-tissue irritation, as well as distal, femoral secondary fractures, because of either the large size of the screws for certain smaller femurs22 or as a result of poor insertion technique.43–45 Furthermore, iatrogenic vascular accidents have been reported during screw hole drilling, screw insertion, or when too long of a screw is used. A high rate of failure occurs if the fracture is treated with a sliding hip screw and a side plate. Clin Orthop Relat Res 1990;252:163-166. Yiannopoulou KG, Anastasiou IP, Ganetsos TK, et al.. BMJ. 37. 23. Injury. By continuing to use this website you are giving consent to cookies being used. Request your next appointment through MyChart! The TFN System consists of a series of cannulated nails, cannulated helical blades, cannulated end caps, and locking bolts and screws. Displaced fractures in highly active patients are treated with total hip replacement. Evolving concepts of stability and intramedullary fixation of intertrochanteric fractures—a review. Aguado d E. Moreno e M.D. The nail acts as a metal buttress to prevent sliding and provides better fixation in unstable fracture patterns. To maintain strength, cortical bone increases in diameter, but the thickness of the cortex itself decreases. Longer operative and fluoroscopy time in the long nail group of patients was observed. Search for Similar Articles Norris R, Bhattacharjee D, Parker MJ. Hemiarthroplasty requires less surgery than a total joint replacement because the acetabulum is not resurfaced. Based on the low periprosthetic fracture rate (0.5%), the authors suggested an individualized approach to the management of these injuries based on the patient's anatomy and surgeon's expertise. Occurrence of secondary fracture around intramedullary nails used for trochanteric hip fractures: a systematic review of 13, 568 patients.

CT scans reveal fractures only when they are displaced. In the single-legged stance of a walking cycle, the femoral head sustains at least 3 times the body weight of loads because of contracture of the abductors muscles. 45. intertrochanteric fracture; cephalomedullary; nailing; distal interlocking. The code 27245: Open treatment of an intertrochanteric, peritrochanteric, or subtrochanteric femoral fracture with an intramedullary implant (which includes a Gamma Nail), with or without locking screws &/or cerclage includes all aspects/methods of the fracture reduction required to align the fracture prior to or during the placement of the internal fixation. Unstable fractures are those in which the femur is broken into four parts or the fracture is of the reverse oblique pattern. The tip-apex distance is the sum of the distances from the tip of the hip screw to the apex of the femoral head as measured on AP and lateral radiographs Baumgaertner et al. Lippincott Journals Subscribers, use your username or email along with your password to log in. Intertrochanteric fractures: ten tips to improve results. Small Battery Drive II User's Manual. 3 Afb. Registered users can save articles, searches, and manage email alerts. 2012;43:686–693. There is relatively paucity of high-quality evidence to support the use of a long over a short nail for the management of these fractures. A randomized prospective controlled trial. Younger patients may opt for screw fixation and hip salvage. 21. 53. People with a slower gait have less forward momentum. 1991;31:1649–1658. Introduction .. Oscillating Saw Attachment II (Crescentic Technique). Implant fixation can be achieved by the injection of bone cement around the prosthesis or by bony ingrowth into the prosthesis. Hip fractures. [Epub ahead of print]. (shown below) The screw provides proximal fragment fixation. In the absence of interlocking screws, the implant transfers axial compaction motion along the longitudinal axis of the nail to the bone. Intertrochanteric intramedullary nailing, in general, refers to an antegrade insertion of a femoral nail with a wider proximal part and proximal slots that allow a single or a couple of lag screws/or a blade to be inserted from the lateral cortex of the femur, passing through the nail slot/s, across the femoral neck, finishing at the subchondral area of the femoral head.
