Comparison of effectiveness of lower extremity axial distractor and traction table assisted closed reduction and intramedullary nail fixation in femoral subtrochanteric fracture / 中国修复重建外科杂志

OBJECTIVE@#To compare the effectiveness of lower extremity axial distractor (LEAD) and traction table assisted closed reduction and intramedullary nail fixation in treatment of femoral subtrochanteric fracture.@*METHODS@#The clinical data of 117 patients with subtrochanteric fracture of femur treated by closed reduction and intramedullary nail fixation between May 2012 and May 2022 who met the selection criteria were retrospectively analyzed. According to the auxiliary reduction tools used during operation, the patients were divided into LEAD group (62 cases with LEAD reduction) and traction table group (55 cases with traction table reduction). There was no significant difference in baseline data, such as gender, age, injured side, cause of injury, fracture Seinsheimer classification, time from injury to operation, and preoperative visual analogue scale (VAS) score, between the two groups ( P>0.05). Total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, closed reduction rate, fracture reduction quality, fracture healing time, weight-bearing activity time, and incidence of complications, as well as hip flexion and extension range of motion (ROM), Harris score, and VAS score at 1 month and 6 months after operation and last follow-up were recorded and compared between the two groups.@*RESULTS@#There were 14 cases in the LEAD group from closed reduction to limited open reduction, and 43 cases in the traction table group. The incisions in the LEAD group healed by first intention, and no complication such as nerve and vascular injury occurred during operation. In the traction table group, 3 cases had perineal crush injury, which recovered spontaneously in 1 week. The total incision length, operation time, intraoperative blood loss, fluoroscopy frequency, and closed reduction rate in the LEAD group were significantly better than those in the traction table group ( P<0.05). There was no significant difference in the quality of fracture reduction between the two groups ( P>0.05). Patients in both groups were followed up 12-44 months, with an average of 15.8 months. In the LEAD group, 1 patient had delayed fracture union at 6 months after operation, 1 patient had nonunion at 3 years after operation, and 1 patient had incision sinus pus flow at 10 months after operation. In the traction table group, there was 1 patient with fracture nonunion at 15 months after operation. X-ray films of the other patients in the two groups showed that the internal fixator was fixed firmly without loosening and the fractures healed. There was no significant difference in fracture healing time, weight bearing activity time, incidence of complications, and postoperative hip flexion and extension ROM, Harris score, and VAS score at different time points between the two groups ( P>0.05).@*CONCLUSION@#For femoral subtrochanteric fracture treated by close reduction and intramedullary nail fixation, compared with traction table, LEAD assisted fracture reduction can significantly shorten the operation time, reduce intraoperative blood loss and fluoroscopy frequency, reduce incision length, effectively improve the success rate of closed reduction, and avoid complications related to traction table reduction. It provides a new method for good reduction of femoral subtrochanteric fracture.

Abstract: Hip fractures are considered a public health problem in the world. Among hip fractures we find subtrochanteric fractures that are defined as proximal femur fractures located in the trochanteric region within 5 cm below the lesser trochanter; and they have an approximate incidence of 15 to 20 per 100,000 people. The objective of this case is to report the success of the reconstruction of an infected subtrochanteric fracture, with a non-vascularized fibular segment and a distal femur condylar support plate. Clinical case: 41-year-old male patient suffering from a right subtrochanteric fracture as a result of a traffic accident that required the use of osteosynthesis material. With subsequent rupture of the cephalomedullary nail in its proximal third, non-union of the fracture and infections at the fracture site. He was treated with multiple surgical lavages, antibiotic therapy, and an unconventional orthopedic and surgical procedure, such as the use of a distal femur condylar support plate and an endomedullary bone graft with a 10-cm segment of non-vascularized fibula. Patient with satisfactory and favorable evolution.

A COMPARATIVE PROSPECTIVE STUDY OF DYNAMIC HIP SCREW AND PROXIMAL FEMORAL NAIL IN TREATMENT OF SUBTROCHANTERIC FRACTURE FEMUR

Subtrochanteric fractures are relatively rare, accounting for 10 - 34% of all hip fractures1,2,3. They may be very difficult to fix, and the risk of failure has been high with loss of the lesser trochanter and the medial buttresses 3,4, Various intramedullary and extramedullary devices have been developed in an attempt to address potential complications of device failure, mal- or non-union and deformities. In our prospective case series 29 subtrochanteric fractures were involved. The aim of this study is to assess fracture union and functional outcome in subtrochanteric fracture femur treated with proximal femoral nailing and dynamic hip screw, and also to evaluate advantages, disadvantages and major postoperative complications associated with the proximal femoral nailing and dynamic hip screw. Conclusion: The average functional scores for the PFN group at 6 months was 31.5 (excellent) which was significantly greater than the DHS group 27.1(good) (p = 0.03). There was no significant difference in time to union in both groups (average 5.7 months for DHS group and 5.2 months for PFN group) (p = 0.26). The intraoperative complication rate for the PFN group was 36% which was significantly higher than the DHS group (0%) (p =0.001). The PFN had a significantly better functional outcome than DHS plating at 6 months. Long term studies may be needed to observe whether the difference persists on further follow ups. The PFN had a significant advantage over the DHS with side plate in subtrochanteric fractures with regards to less blood loss, less requirement for transfusions, better functional scores, less shortening and fewer incidences of postoperative complications. From the study, we consider PFN as better alternative to DHS in the treatment of subtrochanteric fracture femur but is technically difficult procedure and requires more expertise compared to DHS.

Effectiveness analysis of closed or limited open reduction and intramedullary nail fixation in treatment of Seinsheimer type Ⅴ subtrochanteric fracture / 中国修复重建外科杂志

Objective: To investigate the effectiveness of closed or limited open reduction and intramedullary nail fixation in the treatment of Seinsheimer type Ⅴ subtrochanteric fracture. Methods: Between May 2014 and July 2018, 36 patients with Scinsheimer type Ⅴ subtrochanteric fractures were treated with closed or limited open reduction and intramedullary nail fixation. There were 25 males and 11 females with an age of 23-86 years (mean, 55.8 years). The cause of injury included falling in 19 cases, traffic accident in 9 cases, falling from height in 7 cases, and heavy object injury in 1 case; all were fresh closed injuries. The interval between injury and operation was 1-14 days (mean, 6.8 days). There were 18 cases of closed reduction and 18 cases of limited open reduction during the operation. Seventeen cases were fixed with femoral reconstruction intramedullary nail, 5 with InterTan long nail, 14 with lengthened proximal femoral nail anti-rotation, and 7 cases were assisted with auxiliary steel wire binding. After operation, through X-ray film and clinical follow-up, the fracture reduction and maintenance status, internal fixation position, and fracture healing were judged; the range of motion, walking ability, and complications of hip joint were observed, and the function of hip joint was evaluated according to Merle d'Aubigne Postel hip joint scoring standard. Results: All the incisions of medullary operation healed by first intention, and no vascular, nerve injury, or infection occurred. All patients were followed up 12-24 months, with an average of 14.2 months. Among the 36 patients, 1 patient received revision surgery due to varus displacement of femoral head and screw penetration at 2 months after closed reduction, with poor recovery of hip function. X-ray film re-examination showed that the fractures of the other 35 patients healed after 9-15 months, with an average of 11.5 months. During follow-up, there was no complication such as internal fixation failure, fracture redisplacement, bone nonunion or malunion, and deep vein thrombosis of lower extremity occurred. The function of hip joint recovered well, and the patients could walk and squat normally without affecting daily life or work. At last follow-up, according to Merle d'Aubigne Postel hip joint scoring standard, 28 cases were rated as excellent, 4 cases as good, 3 cases as fair, and 1 case as poor, the excellent and good rate was 88.9%. Conclusion: C-arm X-ray fluoroscopic closed or limited open reduction and intramedullary nail fixation for the treatment of Seinheimer Ⅴ type subtrochanteric fracture, if necessary, with the aid of auxiliary steel wire binding, it has the advantages of less blood supply destruction at the fracture end, satisfactory reduction, firm fixation, and early rehabilitation training, with definite effectiveness.

Characteristics and Surgical Outcomes of Intertrochanteric or Subtrochanteric Fractures Associated with Ipsilateral Femoral Shaft Fractures Treated with Closed Intramedullary Nailing: A Review of 31 Consecutive Cases over Four Years at a Single Institution / 대한고관절학회지

PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.

Subtrochanteric Fracture Reduction during Intramedullary Nailing: Technical Note

The subtrochanteric area is the place where mechanical stress is most concentrated in the femur. When a fracture happens, bone union is delayed and nonunion often occurs. The recommended treatment for atypical fractures is an anatomical reduction of the fracture site as the frequency of nonunion is higher than that of ordinary fractures. Various reduction methods have been suggested, and good results have been obtained. On the other hand, the occurrence of posterior displacement of the distal fragment during the insertion of an intramedullary nail is often overlooked. This is probably because the bone marrow of the femur tends to form an elliptical shape in the anteroposterior direction. The author attempted to insert a blocking screw into the distal part of the fracture to prevent posterior displacement of the distal fragment while performing intramedullary nailing of the femur fracture and achieved a good reduction state easily.

Osteonecrosis of the jaw and Bilateral Atypical Femoral Fracture both occurring during treatment for Osteoporosis: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#Osteonecrosis of the jaw (ONJ) and atypical femoral fracture (AFF) are rare potential adverse effects of bisphosphonates and RANKL antibody therapy. The pathogenic mechanisms of both conditions are known to be independent of each other. Here, we report both conditions sequentially occurring in the same patient.An 81-year-old, obese, diabetic, female was admitted due to hypertensive urgency and persistent jaw pain after tooth extraction. The patient has postmenopausal osteoporosis for fourteen years and was on intermittent, unsupervised treatment with alendronate, denosumab and ibandronate. Upon presentation, the patient was noted with tenderness intraorally of tooth number 35 periapical region. This was associated with elevated erythrocyte sedimentation rate and C-reactive protein. Imaging study showed presence of bony sclerosis which represent a sequestrum in the molar area of the left hemi-mandible. Antibiotic infusion and excision and debridement of left posterior mandible were done. Histopathologic finding was consistent with a diagnosis of osteonecrosis of the jaw. The same patient, upon review, had suffered sequential fracture of both femurs during the eighth and eleventh year of treatment with antiresorptive agents. The fractures were transverse, non-comminuted, at the proximal femoral shaft. Each occurred after a minor trauma and was managed with open reduction and internal fixation. Both fractures were consistent with atypical femoral fractures.ONJ and AFF can occur both in the same patient during prolonged treatment with bisphosphonates and denosumab and may suggest a common pathogenic mechanism.

Lateral decubitus intramedullary nailing for femoral subtrochanteric fractures / 中华创伤骨科杂志

Objective To investigate the efficacy of lateral decubitus intramedullary nailing for treatment of subtrochanteric fractures of the femur.Methods From January 2012 to December 2015,23 patients with simple femoral subtrochanteric fracture were treated at Department of Orthopedic Trauma,Changhai Hospital.They were 15 males and 8 females,aged from 19 to 77 years (average,48.3 years).According to the Seinsheimer classification,there were 6 cases of type ⅡB,8 cases of type ⅡC,6 cases of type Ⅲ A,and 3 cases of type ⅢB.Their injuries were caused by traffic accident in 10 cases,falling from a height in 5 cases,and sprain in 8 cases.All patients were treated by closed reduction and anterograde intrarnedullary nailing at lateral decubitus.Their operative time,bleeding volume,fluoroscopic frequency,fracture healing time,functional recovery and complications were recorded and analyzed.Results Their operative time ranged from 55 to 80 min,averaging 65.7 min;their bleeding volumes ranged from 240 to 420 mL,averaging 304.3 mL;their fluoroscopic frequency ranged from 30 to 60 times,averaging 42.7 times.This cohort was followed up for 12 to 28 months (average,17.9 months).Their fracture healing time ranged from 4 to 10 months,averaging 5.5 months.Nonunion occurred in one patient but was cured by secondary operation.The HSS evaluation at the final follow-ups showed 17 excellent cases and 6 good ones,yielding an excellent to good rate of 100％.All the wounds healed by the first intention.No infection,deep vein thrombosis or implant failure was observed.Conclusion As lateral decubitus intramedullary nailing can achieve satisfactory clinical efficacy for subtrochanteric fractures of the femur,the body position of lateral decubitus may be a good alternative.

Surgical Outcomes of Biologic Fixation for Subtrochanteric Fracture Using Locking Compression Plates / 대한고관절학회지

PURPOSE: This study aimed to evaluate the surgical outcomes of biologic plating using locking compression plate-distal femur (LCP-DF) in patients with subtrochanteric fracture of the femur. MATERIALS AND METHODS: Between January 2010 and December 2013, 28 consecutive patients with subtrochanteric fractures of the femur, treated with biologic fixation using LCP-DF, were enrolled. Preoperative values, including patient age, sex, body mass index, fracture type, type of lung injury, and surgical timing from injury to surgery, were retrospectively evaluated. Radiologic assessments included time to union, coronal alignment, rotational alignment, and complications such as implant breakage and screw breakage. Adverse events, including postoperative fat embolism and adult respiratory distress syndrome, infection during the follow-up period, and walking ability at the last follow-up visit, were assessed. RESULTS: Union was achieved in 27 patients (96.4%) after a mean duration of 5.4 months (range, 3-14 months). No patients developed fat embolism or adult respiratory distress syndrome during the hospitalization period of this study. CONCLUSION: Biologic fixation using locking compression plates may represent a safe surgical option which can be utilized in patients with subtrochanteric fracture regardless of injury severity, surgical timing, fracture type, and presence of lung injury.

Clinical Results of Complex Subtrochanteric Femoral Fractures with Long Cephalomedullary Hip Nail / 대한고관절학회지

PURPOSE: Good results of the cephalomedullary nails have been reported in proximal femoral fractures recently. Based on length of nails and shape of screws fixed in a femoral head for proximal fragment fixation, the proper nail length was in dispute. The purpose of this study was to evaluate the clinical and radiological results of a long cephalomedullary hip nail for the treatment of comminuted subtrochanteric femoral fractures. MATERIALS AND METHODS: Twenty-one consecutive patients with severe subtrochanteric femoral fractures who had undergone intramedullary fixation using long-PFNA II between March 2010 and March 2013 were followed-up for over 12 months. Their mean age was 64.8 years old (range, 43-85 years). Sixteen of 22 cases were high energy trauma. According to Seinsheimer's classification, 5 cases were type IV and 16 cases were type V. For radiological assessment, time to union, change of neck-shaft angle, sliding length, tip-apex distance (TAD) and leg length discrepancy (LLD) were measured. For clinical evaluation, a modified Koval index was investigated. RESULTS: Mean operation time was 96 minutes. An average decrease of neck-shaft angle was 4.5°. The average sliding length of the helical blade was 4.2 mm. Average LLD was 3.0 mm, and TAD was 23.0 mm. Mean modified Koval index score at final follow-up was 4.6 points. All the 21 subtrochanteric fractures healed uneventfully on an average of 24.2 weeks (range, 18-30 weeks). CONCLUSION: Long cephalomedullary hip nail provides excellent clinical and radiological outcomes in the comminuted subtrochanteric fracture.

In 1949 Boyd and Griffin Subtrochanteric fracture femur as a variant of peritrochanteric fracture with higher incidence of unsatisfactory result both in the elderly and young. Most of this fracture is with higher incidence of unsatisfactory result after operative treatment This single case study shows one of the unpredicted iotrogenic complications. Material and method: Patient is 78yr female patient with multiple co-morbid conditions with subtrochanetric fracture. Surgery was done with long PFN nail inserted with good purchase in head, reduction check under C-arm with in antero-posterior & lateral view shows little malreduction and nail is out of medulary cavity in proximal fragment. Revision in same sitting not possible due to some medical reasons. Revision surgery done after fitness and reduction held with encieclage wire and bone grafting done. Conclusion: Even without lateral wall support if there is good purchase of screws in head and shaft, there will be good union and good functional outcome.

Study Of Ender’s Nailing In Subtrochanteric Fracture Of Femur In Adults.

Abstracts: Background: Fractures of the subtrochanteric area of the femur represents a difficult therapeutic problem for the orthopaedic surgeon. Comminution, high stress concentration and osteoporosis in this region can lead to failure of fixation, shortening and nonunion. Favourable mechanical conditions are obtained following flexible intramedullary nailing like Ender’s nailing,because axial forces are distributed along the entire length of the nail and bending moments are minimized. Compression of the fracture fragments occur without excessive stress on the nails, enabling the patient to bear weight on the extremity. Methodology: This is a study of 34 cases of subtrochanteric fractures of femur in adults treated by Ender’s nailing at our place. Age ranging from 19 to 70yrs..In our study patient’s distribution according to frank-seinsheimer classification was as follows : Type I: nil, II-a: 1 pt., II-b: 5 pts., II-c: nil, III-a: 10 pts., III-b: 5 pts., IV: 5 pts., V: 8 pts. All the patients were having close fracture. We used 4.5 Enders nails in all patients. In 24 pts.total 3 nails and in 10 pts.total 4 nails were used. In 5 patients open reduction and encirclage wiring was done. In all other patients close reduction was done. Results: Average union time was 15 weeks. No pt. got postope. infection. Excellent and good results were found in 27 pts.out of 34 pts. Conclusion: Average duration of surgery was 1 hour and 10 minutes. Per-operative average blood loss was only 75cc. Post- operatively 23 patients out of 34 patents started partial weight bearing walking from 1stpost operative day. Union rate was 97%, no malunion in coxavara, 6% patient got external rotation deformity.

Treatment of Femur Subtrochanteric Fracture Using the Intramedullary Long Nail; Comparison of Closed Reduction and Minimal Open Reduction / 대한정형외과학회잡지

PURPOSE: The purpose of the study was to evaluate methods for treatment of femur subtrochanteric fractures using the intramedullary long nail. MATERIALS AND METHODS: This retrospective study included 44 patients (44 cases) who were available for follow-up for at least one year. The patients had undergone intramedullary fixation specifically with a long nail for traumatic femur subtrochanteric fractures during the period from June 2005 to May 2012 in Chosun University Hospital. The study compares two groups. For group 1, closed reduction was attempted, and group 2 underwent minimal open reduction. Group 1 included 27 cases, and group 2 included 17 cases. Study parameters included injury mechanism, fracture classification according to the Seinsheimer type, nail design, size of skin incision, alignment, bony union time, malunion or nonunion, and complications. RESULTS: Bony union times were 19.4 weeks (group 1) versus 21.4 weeks (group 2), but there were no statistical differences between the two groups with respect to gender, injury mechanism, fracture classification, or nail design. However, there were significant differences between the two groups with respect to skin incision, malalignment, and complications. Gender, injury mechanism, fracture classification, nail design, size of skin incision, minimal open reduction or close reduction, did not show a significant relationship with bony union. However, in cases of malalignment, the possibility of malunion increased 1.5 times per 1degrees increase in malaligment. CONCLUSION: In treatment of femur subtrochanteric fracture using intramedullary nail, nonunion rate increases when malalignment occurs. Therefore, anatomical reduction with minimal open reduction is necessary if closed reduction is not satisfactory.

Subtrochanteric Fracture: Emphasis on Surgical Techniques in Nailing / 대한정형외과학회잡지

Intramedullary nailing is considered the most biomechanically advantageous therapeutic modality in the treatment of subtrochanteric femoral fractures. Many technical pitfalls and difficulties in nailing are well known. Reduction of the proximal fragment in a flexed, abducted, and externally rotated position should be performed before nailing of subtrochanteric fractures in order to avoid malalignment and nonunion. In this review, various reduction techniques to control the proximal fragment which are useful in nailing will be discussed.

Treatment of the Femoral Fracture Using Sirus(R) Nail: A Comparison of Complication according to the Entry Potal

PURPOSE: The purpose of this study is to analyze the clinical results of fixation using Sirus(R) nail in patients with femoral subtrochanteric and shaft fracture and the difference in the frequency of complications according to the entry portal. MATERIALS AND METHODS: From July 2006 to August 2013, at least 1-year clinical follow-up, we retrospectively analyzed 36 cases with femoral subtrochanteric (15 cases) and shaft fracture (21 cases) who underwent surgery using Sirus(R) nail. We reviewed the records of operation time, intra-operative amounts of bleeding and complications. At last follow-up, we reviewed clinical results by Ray-Sanders criteria and analyzed the periods of bone union on the radiograph. We also measured changing of the femoral neck-shaft angle in the subtrochanteric fractures and angulation in the shaft fractures, respectively. Considering anatomical variation of the trochanter and fracture position of subtrochanteric and femoral shaft, entry points were divided into subgroups, and the clinical results were compared. RESULTS: The mean Ray-Sanders score was 27.4, 27 cases (75.0%) were good or excellent. The mean periods of bone union was 21.1 weeks in 31 cases. The mean neck-shaft angles were 135.7o preoperatively, 130.2o postoperatively. The mean angulation of the femur was 24.4o preoperatively, 2.4o postoperatively in patients of femoral shaft fractures. Despite no statistical significance, greater trochanter tip entry point and lateral entry point had a higher rate of frequency than medial entry point, with respect to the occurrence of iatrogenic fracture and malalignment. CONCLUSION: Using Sirus(R) nail for femoral subtrochanteric and shaft fractures showed good clinical and radiographic results and a high rate of union. Medial entry point yielded slightly better results in the occurrence of iatrogenic fracture and malalignment, compared to greater trochanter tip entry point and lateral entry point.

Effect of proximal femoral nailing in proximal third femur fracture.

Background: Proximal third femur fractures are common fractures seen in community. Till date large numbers of intramedullary and extramedullary implant were used in the treatment of these fractures. These fractures differ significantly from femoral shaft fractures and more proximal femoral fractures in mechanisms, treatment and complications. In 1996 AO group has introduced proximal femoral nail (PFN) for treatment of these fractures. The use of PFN in both these fractures resulted in rotational stability along with union in more anatomic position. Aims & Objective: To prove the advantages of PFN like (1) close reduction of fracture which decreases the blood loss and chance of infection; (2) controlled impaction of the fracture; (3) rotational stability; and (4) load bearing capacity of the implant. Material and Methods: We have done a retrospective study of proximal femur fractures operated with proximal femoral nailing at our institute with follow up of 5 – 36 months. Our study included 30 patients with 8 patients having intertrochanteric fracture and 22 patients having subtrochanteric fracture. Patient was asked to come for follow up on 1, 2, 3 and 6 months from the date of surgery. At each follow up patient was assessed clinically as per Harris Hip score12 and x ray AP/LAT view of hip with femur is taken. Results: It concludes that according to Boyd and Griffith classification type II is the most common variety. In our study excellent to good results noted in 74% patients. All of them performing their routine normal activity well. 5 patients had poor results. Complication rate in our study was much lower. There was only one infection which was known case of diabetes mellitus. Conclusion: The procedure takes less time and the patient can be mobilized fast postoperatively as well after fixation with PFN. PFN should always be considered for management of subtrochanteric fractures in young as well as elderly patients who have multiple pre-existing illnesses. PFN is a closed nailing procedure which achieves a Biological Fracture fixation with minimal blood loss, preserving the fracture hematoma and helping easy healing of the unstable subtrochanteric femoral fracture as well as intertrochanteric fracture.

Fixation of the Femoral Subtrochanteric Fracture with Minimally Invasive Reduction Techniques

PURPOSE: To evaluate the results of using minimally invasive reduction techniques in patients with femoral subtrochanteric fracture. MATERIALS AND METHODS: We retrospectively analyzed 40 patients (41 cases) with subtrochanteric fracture who underwent using minimally invasive reduction techniques. The mean age was 61.4 years (15-89 years), and the mean follow-up period was 32.7 months (12-66 months). Clinical results were assessed using the Parker-Palmer mobility score and the Salvati-Wilson hip functional score. Radiographic results were evaluated using bone union time and femur neck-shaft angle. RESULTS: No significant difference was observed in the pre- and postoperative Parker-Palmer mobility score. Salvati-Wilson hip functional score showed more than good grade in 37 cases (90%) at the last follow-up. Union was achieved in all 41 cases at an average of 22.5 weeks (18-30 weeks). The mean femoral neck-shaft angle immediately postoperatively was 128.8 degrees (120-140 degrees), and the mean difference versus contralateral sides was 2.5 degrees varus (-6-13 degrees). CONCLUSION: Fixation of femoral subtrochanteric fracture using minimally invasive reduction techniques showed excellent clinical and radiographic results and low complication rate.

The Treatment of Subtrochanteric Fractures with Proximal Femoral Nail Antirotation

PURPOSE: The purpose of this study was to analyze the results of treating subtrochanteric femoral fractures with proximal femoral nail antirotation (PFNA). MATERIALS AND METHODS: Twenty five consecutive patients diagnosed with subtrochanteric femoral fractures underwent intramedullary fixation using PFNA and followed-up for over 12 months. According to the Seinsheimer's classification, there were 2 type IIA, 9 type IIB, 2 type IIIA, 3 type IV and 9 type V. According to the AO classification, there were 10 type A, 9 type B and 6 type C. There were 16 cases of closed reduction group and 9 cases of limited open reduction group. Retrospectively, radiological outcomes were assessed at the union period, change of neck shaft angle, tip-apex distance, Cleveland index, sliding of lag screw and complication. RESULTS: Union was achieved in 23 of 25 cases, over an average of 17 weeks. Limb length shortening below 2 cm occurred in 7 patients. The Cleveland index was shown in 80% of 5, 6, 8 and 9 zone; the tip apex distance was 19.6 mm; the mean sliding distance was 4.4 mm; and the mean change of femur neck and shaft angle was varus 3 degree at the final follow-up. Complications included 3 cases of delayed union and 2 cases of nonunion. CONCLUSION: With its early bony union, ambulation, rehabilitation and low complication, PFNA is a useful and reliable choice for the treatment of subtrochanteric fractures of the femur. Limited open reduction and additional fixation such as cable grip are recommended if it is difficult to obtain anatomical reduction by closed reduction.

Bilateral Insufficiency Fracture of Medial Subtrochanteric Area of the Femur: A Case Report / 대한고관절학회지

A non-traumatic, incomplete insufficiency fracture commonly involves the lateral side of the femoral cortex; whereas a non-traumatic, incomplete stress fracture commonly involves the medial side of the femoral cortex. Here, we describe a case of a 66-year-old woman with a two-month history of bilateral thigh pain without trauma or medication usage who was diagnosed with bilateral subtrochanteric insufficiency fractures involving the medial side of the femoral cortex.

Efficacy of Percutaneous Cerclage Wiring in Intramedullary Nailing of Subtrochanteric Femur Fracture: Technical Note

The subtrochanteric fractures of femur have high rates of delayed union or nonunion due to less-dense cancellous bone, insufficient cortical blood flow and high stress concentration. Anatomical reduction and rigid internal fixation are important in this region; however, an open reduction might damage the biological environment at the fracture site as well as increase the risk of nonunion. We present our experience with nine cases of subtrochanteric femur fractures surgically fixated with intramedullary nailing after percutaneous cerclage wiring through minimal incision.
