Intertrochanteric fractures are composed of different anatomic patterns that vary in their degree of stability following open reduction and internal fixation. A particularly unstable group is classified as AO/OTA 31-A3, with the fracture pattern described as reverse oblique or transverse. The purpose of this study was to compare the results of intramedullary fixation with those of plate fixation for these intertrochanteric fractures in elderly patients.
                Thirty-nine elderly patients with AO/OTA 31-A3 intertrochanteric fractures of the femur were randomized into two treatment groups and were followed for a minimum of one year. The nineteen patients in Group I were treated with a 95 fixed-angle screw-plate (Dynamic Condylar Screw), and the twenty patients in Group II were treated with an intramedullary nail (Proximal Femoral Nail). The treatment groups were comparable with regard to all demographic and injury variables.
                Patients treated with an intramedullary nail had shorter operative times, fewer blood transfusions, and shorter hospital stays compared with those treated with a 95 screw-plate. Implant failure and/or nonunion was noted in seven of the nineteen patients who had been treated with the 95 screw-plate. Only one of the twenty fractures that had been treated with an intramedullary nail did not heal.
                The results of our study support the use of an intramedullary nail rather than a 95 screw-plate for the fixation of reverse oblique and transverse intertrochanteric fractures in elderly patients. Intramedullary nailing has been the gold standard in the management of lower limb fractures by virtue of advantage of early joint mobilisation and weight bearing. They are being increasingly used in the peri-trochanteric fractures of femur. Biomechanical studies have proved the supremacy of single femoral neck screw construct over two femoral neck screws along with the intramedullary nails in osteoporotic bones due to lower incidence of complications. This randomised clinical trial was conducted to study the clinico-radiological outcome of single and two-femoral neck screw construct in the management of unstable trochanteric fractures in the elderly osteoporotic bones. Although there was no significant difference in the clinical outcome in the two groups, less sliding of the femoral neck screws was noted with two-femoral neck screw configuration. The tip-apex distance was also significantly lower in the two-screw construct compared to that of the single screw construct. This study to our knowledge is the first randomised control clinical trial evaluating the effectiveness of one and two femoral neck screw configuration of intra-medullary nails in the management of unstable trochanteric fractures. We studied 217 patients with an unstable trochanteric or subtrochanteric fracture who had been randomly allocated to treatment by either internal fixation with a standard Gamma nail (SGN) or a Medoff sliding plate (MSP, biaxial dynamisation mode). Their mean age was 84 years (65 to 99) and they were reviewed at four and 12 months after surgery. Assessments of outcome included general complications, technical failures, revision surgery, activities of daily living (ADL), hip function (Charnley score) and the health-related quality of life (HRQOL, EQ-5D). The rate of technical failure in patients with unstable trochanteric fractures was 6.5% (6/93) (including intra-operative femoral fractures) in the SGN group and 5.2% (5/96) in the MSP group. In patients with subtrochanteric fractures, there were no failures in the SGN group (n = 16) and two in the MSP group (n = 12). In the SGN group, there were intra-operative femoral fractures in 2.8% (3/109) and no post-operative fractures. There was a reduced need for revision surgery in the SGN group compared with the MSP group (8.3%; 9/108; p = 0.072). The SGN group also showed a lower incidence of severe general complications (p < 0.05) and a trend towards a lower incidence of wound infections (p = 0.05). There were no differences between the groups regarding the outcome of ADL, hip function or the HRQOL. The reduction in the HRQOL (EQ-5D(index) score) was significant in both groups compared with that before the fracture (p < 0.005). Our findings indicate that the SGN showed good results in both trochanteric and subtrochanteric fractures. The limited number of intra-operative femoral fractures did not influence the outcome or the need for revision surgery. Moreover, the SGN group had a reduced number of serious general complications and wound infections compared with the MSP group. The MSP in the biaxial dynamisation mode had a low rate of failure in trochanteric fractures but an unacceptably high rate when used in the biaxial dynamisation mode in subtrochanteric fractures. The negative influence of an unstable trochanteric or subtrochanteric fracture on the quality of life was significant regardless of the surgical method. To compare closed intramedullary nailing to open reduction and internal fixation using a fixed angle blade plate for the management of subtrochanteric femoral fractures.
                58 patients were equally randomised to undergo either an intramedullary nailing (IN) or fixed angle blade plating (BP).
                There were no significant differences between the 2 groups with regard to age, time to surgery, operating time, receipt of blood transfusions, duration of hospital stay, or fracture classification. The revision rate was 28% (8/29) in the BP group and none in the IN group; the difference was statistically significant.
                Internal fixation using a fixed angle blade plate for subtrochanteric femoral fractures has higher implant failure and revision rates, compared to closed intramedullary nailing. To compare the surgical complications and functional outcome of the Gamma nail intramedullary fixation device versus the Richards sliding hip screw and plate device in intertrochanteric femoral fractures.
                A prospective, randomised controlled clinical trial with observer blinding.
                A regional teaching hospital in the United Kingdom.
                All patients admitted from the local population with intertrochanteric fractured femurs were included. There were 400 patients entered into the study and 399 followed-up to one year or death.
                The devices were assigned by randomization to either a short-type Gamma nail (203 patients) or a Richard's-type sliding hip screw and plate (197 patients).
                The main surgical outcome measurements were fixation failure and reoperation. A functional outcome of pain, mobility status, and range of movement were assessed until one year.
                The requirement for revision in the Gamma nail group was twelve (6%); for Richard's group, eight (4%). This was not statistically different (p = 0.29; odds ratio, 1.48 [0.59-3.7]). A subcapital femoral fracture occurred in the Richard's group. Femoral shaft fractures occurred with four in the Gamma nail group (2%) and none in the Richard's group (p = 0.13). Three required revision to another implant. Lag-screw cut-out occurred in eight patients in the gamma nail group (4%) and four in the Richard's group (2%). This was not statistically significant (p = 0.37; odds ratio, 2.29 [0.6-9.0]). The development of other postoperative complications was the same in both groups. There was no difference between the two groups in terms of early or long-term functional status at one year.
                The use of an intramedullary device in the treatment of intertrochanteric femoral fractures is still associated with a higher but nonsignificant risk of postoperative complications. Routine use of the Gamma nail in this type of fracture cannot be recommended over the current standard treatment of dynamic hip screw and plate. In a prospective randomized study, we compared the new intramedullary implant of the gliding nail to the gamma nail in the fixation of 80 unstable trochanteric fractures in elderly patients. The preconditions of both groups were comparable. We found no differences concerning the operation time, blood loss, period of stationary treatment or social situation. Also, the anatomic reconstruction and the long-term function according to the Merle d'Aubigne score were comparable. Regarding postoperative complications, the gliding nail showed a minor tendency of cutting out; this we attribute to the special design of the dynamic blade and regard it as the most favourable advantage of this new implant. The intramedullary hip screw system Classic-Nail and the Dynamic Hip Screw (DHS) were evaluated in a prospective-randomized clinical trial for operative treatment of trochanteric femur fractures. Hundred and ten geriatric patients (mean age 82 years) were runningly included in the study (56 Classic Nail, 54 DHS). No significant differences between the two study groups were observed with regard to treatment and follow-up data. With the Classic-Nail one complete femur shaft fracture and one incomplete fracture occurred at the tip of the nail intraoperatively and could successfully be fixed with cerclage wires. In the DHS group two patients underwent reoperation for significant loss of reduction early postoperatively. At an average follow-up of 3.7 months all fractures were healed with no difference in functional outcome between the two groups.--Classic Nail and DHS both lead to equally good results in the operative treatment of trochanteric femur fractures. This study aimed at comparing the results obtained with a sliding screw plate and an experimental device including a small-diameter nail that can be placed with a mini-invasive approach and provides a stable fixation.
                Randomized prospective study.
                University hospital.
                The study included two groups with thirty fractures of the trochanteric area.
                In both groups, the surgical procedure was carried out on patients placed on a traction table in a supine position, under an x-ray amplifier. Sliding screw plates (THS) were set in place according to the usual open technique. Nails were placed through a twenty-millimeter supratrochanteric cutaneous incision. This experimental system comprised a locked intramedullary nail with two nonparallel seven-millimeter cervicocephalic screws.
                The comparison between the two groups was based on the surgical procedure (time, duration of x-ray irradiation, and total blood loss); the initial postoperative period (complications, duration of hospital stay, and the time before returning home); the time before full weight bearing became effective; the functional and social recovery; mortality; and the quality of immediate and final anatomic restitution and healing.
                Operating time (p < 0.001) and blood loss (p < 0.001) were lower in the nail group, and no blood transfusion was required. Postoperative pain (p < 0.01), time necessary to support full weight bearing (p < 0.02), and time before returning home (p < 0.05) were reduced in the nail group. All fractures healed in the same amount of time, with good anatomic results in the nail group, whereas ten impactions beyond ten millimeters occurred in the plate group. No difference was found between the two groups in walking ability and autonomy recovery, but hip function (p < 0.05) was better in the nail group.
                This preliminary clinical study has shown the advantages of this mini-invasive technique. It could not evaluate all the possible disadvantages inherent in the method. These points will be evaluated in a multicenter study justified by these preliminary results. To compare the results between a sliding compression hip screw and an intramedullary nail in the treatment of pertrochanteric fractures.
                Prospective computer-generated randomization of 206 patients into two study groups: those treated by sliding compression hip screw (Group 1; n = 106) and those treated by intramedullary nailing (Group 2; n = 100).
                University Level I trauma center.
                All patients over the age of fifty-five years presenting with fractures of the trochanteric region caused by a low-energy injury, classified as AO/OTA Type 31-A1 and A2.
                Treatment with a sliding compression hip screw (Dynamic Hip Screw; Synthes-Stratec, Oberdorf, Switzerland) or an intramedullary nail (Proximal Femoral Nail; Synthes-Stratec, Oberdorf, Switzerland).
                Intraoperative: operative and fluoroscopy times, the difficulty of the operation, intraoperative complications, and blood loss. Radiologic: fracture healing and failure of fixation. Clinical: pain, social functioning score, and mobility score.
                The minimum follow-up was one year. We did not find any statistically significant difference, intraoperatively, radiologically, or clinically, between the two groups of patients.
                There is no advantage to an intramedullary nail versus a sliding compression hip screw for low-energy pertrochanteric fractures AO/OTA 31-A1 and A2, specifically with its increased cost and lack of evidence to show decreased complications or improved patient outcome.
With its lower complication rate in comparison with intramedullary nails, and absence of functional outcome data to the contrary, the SHS appears superior for trochanteric fractures. Further studies are required to confirm whether more recently developed designs of intramedullary nail avoid the complications of previous nails. Intramedullary nails may have advantages over fixed angle plates for subtrochanteric and some unstable trochanteric fractures, but further studies are required.
