Objective To evaluate the effectiveness of InterTan in the treatment of femoral intertrochanteric fractures. Methods Between April 2009 and July 2009, 57 patients with femoral intertrochanteric fracture were treated with InterTan. There were 33 males and 24 females with an average age of 68 years (range, 45-88 years). The locations were left side in 31 cases and right side in 26 cases and all fractures were closed fractures. According to Association for Osteosynthesis/Orthopaedic Trauma Association (AO/OTA) classification, there were 23 cases of type 31-A1, 27 of type 31-A2, and 7 of type 31-A3. The disease duration was 2 to 8 days with an average of 3.3 days. The data of operative time, blood loss, perioperative blood transfusion, hospital ization day, fracture heal ing time, and Harris hip score were recorded. Results The operative time and the blood loss were (74.5 ± 19.7) minutes and (148.8 ± 79.6) mL, respectively. There were significant differences in the operative time and the blood loss among the AO/OTA subgroups (P lt; 0.05). Twenty-five patients required a blood transfusion and the transfusion volume was (264.0 ± 90.7) mL. The average hospital ization days were 7 days (range, 6-9 days). Thirty-five patients were followed up 12 to 15 months (13.3 months on average). X-ray films showed that all fractures healed within (2.8 ± 0.8) months. The heal ing time of fracture was (2.4 ± 0.6), (2.9 ± 0.9), and (3.8 ± 0.5) months in 31-A1 subgroup, 31-A2 subgroup, and 31-A3 subgroup, respectively. There was no significant difference in heal ing time of fracture between 31-A1 subgroup and 31-A2 subgroup (P gt; 0.05), and there were significant differences between 31-A3 group and 31-A1 subgroup, 31-A2 subgroup (P lt; 0.05). No shortening, cut-out, varus malposition, femoral shaft fracture, or implant failures was found. The Harris score at the final follow-up was 84.5 ± 8.2 with an excellent and good rate of 80% (15 cases of excellent, 13 of good, 6 of fair, and 1 of poor). Twenty patients (57%) recovered the walking abil ity. Conclusion The new intertrochanteric antegrade nail of InterTan can be used to treat femoral intertrochanteric fractures with good cl inical outcomes, high union rate, and less compl ications.
Objective To identify an evidence-based treatment for an elderly patient with intertrochanteric fractures. Methods Clinical problems were presented on the basis of the patient’s conditions, and evidence was collected from the NGC (2000 to 2009), The Cochrane Library (Issue 4, 2009), TRIP Database, PubMed (1966 to 2009) and CBM (1978 to 2009). Treating strategies were formulated in terms of the three-combination principle (best evidence, the doctor’s professional knowledge and the patient’s desire). Results Three guidelines and sixteen studies were included. The current evidence indicated that surgery was the preferred solution to intertrochanteric fractures of the elderly patient. The sliding hip screw (SHS) appeared superior to others. There was insufficient evidence to support the routine use of closed suction drainage in orthopedic surgeries. Early surgery was associated with shorter hospital stay and improved mortality. Antibiotic prophylaxis significantly reduced infections. In order to lower the risk of venous thromboembolism, pharmacological prophylaxis should be carried out when the patient was admitted to hospital and be assisted with mechanical prophylaxis after surgery. Nutritional supplementation was conducive to the recovery of the patient. Rehabilitation ought to be performed as soon as possible. Considering the patient’s condition, the treatment option was established according to the available evidence and guidelines. Short-term follow-up showed a good outcome. Conclusion Through the evidence-based method, an individual treatment plan could obviously improve the treatment effect and prognosis.
Objective To investigate the effect of treatment with proximal femoral nail (PFN) on femur intertrochanteric fractures in the old. Methods A retrospective study of 62 patients with femur intertrochantericfractures treated with PFN from October 2001 to September 2003 was carried out.The data of operative time, blood loss, intraoperative complications, wound drainage, postoperative complications, healing time, and hip function were recordedand compared with previous literature so as to evaluate the effect. Results All patients were followed up for 8-22 month(13.6 months on average). Intraoperative fracture occurred again in 2 cases. Two patients died of brain embolism and pulmonary infection respectively. Heterogeneous ossification occurred in 2 cases. Hip varus occurred in 1 case. Extra hip anteversion occurred in 1 case. The effect of other cases was satisfactory. The operative time was 76.5±29.1 min, the mean blood loss was 385.7±98.4 ml, the wound drainage was 45.5±21.7 ml, and the healing time was 13.2±3.8 weeks. According to the Sanders post-trauma hip function assessing system, the excellent and good rate was 89.6%. Conclusion The application of PFN is characterized by short operative time, less blood loss, stable fixation, so it is an effective way to treat femur intertrochanteric fracture in the old.
Objective To investigate the development of dynamic hipscrew (DHS) internal fixation in the treatment of intertrochanteric femur fractures. Methods The latest relevant articles were reviewed extensively, including biomechanics and clinical application research. Results DHS is the effective selection for the treatment of intertrochanteric femur fractures, especially by the innovation of DHS structure, operative manipulation.Conclusion Treatment of intertrochanteric femur fractures with DHS is still a gold level, but strict selection of patients, proficiency operation and invasive manipulation are the most essential principles.
ObjectiveTo summarize the progress on the distal interlocking screw of cephalomedullary nail for intertrochanteric fractures. MethodsRelated literature concerning the distal interlocking screw of cephalomedullary nail was reviewed and analyzed in terms of biomechanics, clinical application, operating difficulties, and complications. ResultsDistal interlocking screw can provide extra torsional stiffness in both short and long cephalomedullary nail. It is applied in most clinical cases. In long cephalomedullary nail, placing the distal interlocking screw increases the operative time for fixation and the amount of radiation exposure notably. In short cephalomedullary nail, placing the distal interlocking screw can cause adjacent vascular injury, stress concentration, and secondary fracture around the screw. ConclusionWhen the fracture is stable (type A1, type A2.1), it can be fixed solidly without the distal interlocking screw, but prefers to use a long nail. In unstable fracture, the distal interlocking screw should be used to prevent rotational displacement of the femur shaft and the failure of the nail.

Methods Twenty-eight patients with femoral intertrochanteric fractures including 11 males and 17 females receiving external fixator treatment between July 2007 and October 2009 were enrolled in this study. Their age ranged from 74 to 91 years old with the average to be 81 years. Twenty-five patients had the disease because of ground falls, and the other 3 were due to traffic accidents. Based on the Evans Type classification, there were 1 Type-Ⅰ case, 15 Type-Ⅲ cases, and 12 Type-Ⅳ cases. The time between injury and surgery was ranged from 2 to 7 days. Results All incisions of the patients healed during phase Ⅰ without delayed healing or other early complications. Follow-up was done to all the patients for 5 to 14 months, averaging 9 months. X-ray showed all fractures healed, and the healing time ranged from 11 to 24 weeks with an average of 17 weeks. No varus or leg shortening or other complications occurred. Three months after surgery, based on the Harris hip score for functional evaluation, there were 18 excellent cases, 7 good cases and 3 poor cases with a excellent and good rate of 89.3%. Mild pin tract infection was detected in 7 patients, moderate in 5, and severe in 2 with a total pin tract infection rate of 50%. Two patients with diabetes suffering from severe pin tract infection recovered by local medication and antibiotics, but the infection reoccurred repeatedly till the healing nails were taken. No bone infection of ulcers occurred, and the existing complications were not aggravated. Conclusion Treatment of intertrochanteric fractures with multifunctional external fixator is minimally invasive, simple, and consistent with biomechanical principles, which can promote early activities out of bed and early fracture healing for the patients.
