Refining the indications for surgery after proximal femoral fracture.

Many patients die shortly after surgery for proximal femoral fracture. These patients are subjected to painful operative procedures that do not improve their outcome. We attempted to identify such patients with a case-controlled study of variables associated with death in hospital after proximal femoral fracture. Bronchopneumonia, ASA grade 4, heart failure and malnutrition were significantly associated with death but the latter two variables alone were insufficiently specific to justify withholding surgical treatment. However, 90% of patients with bronchopneumonia and those deemed unfit for anaesthesia died shortly after admission and their condition was not improved by active intervention. We suggest that it is kinder to withhold early surgery in this population.

Intraoperative femoral fractures in cementless total hip arthroplasty.

Ten patients with intraoperative femoral fractures during primary cementless total hip arthroplasty were matched by age, sex, weight, diagnosis, and length of follow-up to 20 patients who had primary cementless total hip arthroplasty without this complication. All fractures were identified in the operating room, and treatment was individualized for each case. Initial stability of the implant was felt to be satisfactory for all cases despite this complication. The mean follow-up was 2.3 years. In this series, no difference was found in clinical or roentgenographic results after cementless total hip arthroplasty between patients who had an intraoperative femoral fracture and patients who did not have this complication. If initial stability of the implant is satisfactory, despite intraoperative fracture, good clinical results can be expected with cementless total hip arthroplasty.

Minimal-invasive treatment of distal femoral fractures with the LISS (Less Invasive Stabilization System): a prospective study of 30 fractures with a follow up of 20 months.

BACKGROUND: There is no consensus on the best treatment of distal femoral fractures. PATIENTS AND METHODS: In a prospective study, we treated 29 patients with 30 distal femoral fractures with the Less Invasive Stabilization System (LISS) from 1997 to 2000. Almost 1/2 of them had open fractures, 1/3 extraarticular type A and 2/3 articular fractures type C (AO classification) and these had been caused by high-energy trauma with concomitant severe injuries or osteoporosis. RESULTS: The follow-up examinations after mean 20 (13-42) months consisted of radiographs, and determination of the Lysholm Knee Score and Knee Society Score (KSS). The outcome correlated with the severity of the fracture, anatomic reduction, exact positioning and fixation of the LISS and concomitant injuries. INTERPRETATION: We found the LISS for treatment of distal femoral fractures of all types to be a safe procedure with good results after careful planning and experience with this surgical technique. There is usually no need for primary cancellous bone grafting.

Soft-tissue interposition of femoral fractures. Detection by ultrasonography during closed nailing.

We have compared the sonographic findings of six femoral fractures with soft-tissue interposition which required open reduction with those of a control group of 40 other femoral fractures. Ultrasound assessment before operation showed that the fractured end of the proximal fragment had penetrated the quadriceps muscle anteriorly while the distal fragment lay beneath it. Transverse scans showed less soft-tissue thickness over the end of the proximal fragment in the problem cases. Radiographic image intensification did not provide any additional information. Ultrasound is of value in demonstrating soft-tissue interposition at the fracture site before femoral nailing.

Femoral neck-shaft angle in extra-capsular proximal femoral fracture fixation; does it make a TAD of difference?

The effect of femoral neck-shaft angle and implant type on the accuracy of lag screw placement in extra-capsular proximal femoral fracture fixation was investigated. Radiographs of all extra-capsular proximal femoral fractures seen in one unit over 18 months were reviewed. Of 399 cases, 307 (237 female, 70 male) were included in the study as they had no contra-lateral proximal femoral metal work. Femoral neck-shaft angle (NSA) of the uninjured hip and magnification adjusted tip-apex distance (TAD) of femoral head lag screw were measured. Type of fixation implant was 135 degrees classic hip screw (CHS) (n=144) or 130 degrees intra-medullary hip screw (IMHS) (n=163). Mean contra-lateral NSA was 130.2 degrees (112.9--148 degrees ) and 64 patients (58 female, 6 male) had a NSA <125 degrees . Mean adjusted TAD was 18.7 mm (5.8--43.8mm) and 88.9% of cases had a TAD of less than 25 mm. TAD values were significantly greater using an IMHS if NSA was <125 degrees than if NSA was >125 degrees (p=0.028). This was not the case with the CHS. The use of the 130 degrees -IMHS in patients with a NSA <125 degrees leads to poorer lag screw placement than if NSA >125 degrees and caution is advocated when using this device in such cases.

[Comparison of various kinds of internal fixations in unstable intertrochanteric femoral fracture].

OBJECTIVE: To explore the effects of various kinds of internal fixations on unstable intertrochanteric femoral fractures. METHODS: From January 2000 to December 2004, 88 cases of unstable intertrochanteric femoral fractures were treated. There were 52 males and 36 females (aged 19-86 years). Twenty-two cases were caused by fall from height, 36 by motor vehicle accident and 20 by fall and 10 by tumble. They were divided into 4 groups according to 4 kinds of internal fixations: dynamic hip screw (DHS, group A, n=42), anatomical proximal femur bone plate (group B, n = 23), proximal femoral nail (PFN, group C, n = 8)and dynamic condylar screw (DCS, group D, n = 15). According to the modified Evan's classification, fractures were all unstable type and were classified as follow types: group A (15 type III, 8 type IV and 19 type V); group B (12 type III, 5 type IV and 6 type V); group C (3 type III, 2 type IV and 3 type V); and group D (10 type III, 3 type IV and 2 type V). The data of operative time, intra-operative blood loss, intra-operative complications, fluoroscopy exposures, clinical healing time of fracture, post-operative restored function and postoperative complications were recorded and analyzed statistically using the SPSS 12.0 software package. RESULTS: All patients were followed up for 12-48 month (18 months on average). All patients achieved clinical healing. Coxa varus occurred in 3 cases of group A, in 1 case of group C and in 3 cases of group D. The differences were of no statistical significance in operative time and postoperative complications between 4 groups (P>0.05). The difference was of statistical significance in the blood loss between groups A, B and groups C, D (P<0.05) but no statistical significance between group C and group D (P>0.05). The difference was of statistical significance in the fluoroscopy exposures, clinical healing time of fracture and postoperative complications between group B and the other groups (P<0.05). The difference was of statistical significance in the post-operative restored functions between group D and the other groups (P<0.05). CONCLUSION: The anatomical proximal femur bone plate is a useful device in the treatment of unstable intertrochanteric femoral fracture. The operative manipulation is simple and the hip functions recover well.

"Fast tracking" patients with a proximal femoral fracture.

OBJECTIVE: To assess the management of elderly patients presenting to the accident and emergency (A&E) department with a proximal femoral fracture. METHODS: A retrospective audit carried out on 30 patients with proximal femoral fracture showed an unacceptably long waiting time in the A&E department. A new "fast track" system for managing these patients, involving the use of a flow chart for expediting admission, was devised. A prospective study of 100 patients > 60 years of age with proximal femoral fracture admitted by fast track system was then carried out. RESULTS: Implementation of the fast track system resulted in earlier admission to the ward (median time to admission 2.5 h v 4.5 h in the retrospective audit, P < 0.001). Eighteen patients were not admitted by fast track during the study period, in some cases because of inconclusive diagnosis or because there was no identifiable orthopaedic bed; mean admission time for this group was 4 h 8 min. CONCLUSIONS: The fast track system was of benefit to all involved, including the patient, A&E staff, ward staff, and orthopaedic personnel.

[Treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail].

OBJECTIVE: To evaluate the results of the treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail. METHODS: From Jun. 1999 to Sep. 2003, 74 patients with femoral fractures were treated by intramedullary interlocking nail (inverse limited marrow cavity rasping). There were 62 males and 12 females. Among them, 5 cases were type 32A1, 7 cases were type 32A2, 12 cases were type 32A3, 35 cases were type 32B2, and 15 cases were type 32C2. RESULTS: Seventy-four patients were followed up for 13 to 29 months (15.4 months in average). The time for fracture union ranged from 3 to 5 months (3.8 months in average). The overall rate of excellence was 98.7% by Wuyuesong grading. There was 1 case of non-union, 1 case of delayed infection, and 2 cases of bent screw. CONCLUSION: The treatment on femoral fractures with inverse limited marrow cavity rasping intramedullary interlocking nail is easy to operate and has minimum impairment to local circulation. It also promotes the healing and early function.

Supracondylar nailing of distal periprosthetic femoral fractures.

Seven patients who sustained complex distal femoral fractures above total knee arthroplasties all treated by supracondylar (retrograde) femoral nailing were retrospectively evaluated. All the patients demonstrated uncomplicated postoperative follow-ups and returned to weight bearing between 2 and 3 months after surgery. No delayed healing occurred and alignment of the femur was satisfactory.

Mid- to long-term clinical findings in nailing of distal femoral fractures.

The purpose of the study was to evaluate clinical long-term results after nailing of distal femoral fractures. The first 22 consecutive cases of distal femoral fractures in 22 patients (2 males and 20 females, age 65 years, range, 16-97 years) treated with retrograde femoral nailing from October 1994 to May 1997 are reported. Indications were AO 33 A1 (n = 7), 33 A2 (n = 2), 33 A3 (n = 3), and 33 C2 (n = 7) fractures. In 11 cases these were periprosthetic fractures of either total hip arthroplasty or hemiarthroplasty of the hip (five) or dynamic hip screw (six), four patients were polytraumatized, one patient had a floating-knee injury. No infections or thrombosis were observed postoperatively. In 17 cases primary union was achieved within 11 weeks (8-17 weeks); five patients died before consolidation. Patients returned to full weightbearing after 5 weeks (4-12 weeks); active knee motion ranged from 80 degrees to 130 degrees. In five patients slight malalignment < 10 degrees was radiographically assessed, with two showing incipient degenerative joint disease. Patients younger than 60 years returned to full preoperative activity level. Eleven patients surviving an average of 5.2 years (4.3-6.9 years) were available for long-term follow-up. As a subgroup they were evaluated according to the Leung score for distal femoral fractures with seven excellent and four good results and an average score of 84.3 points (70-92 points). The mid- to long-term results confirm retrograde femoral nailing to be a good alternative to plate osteosynthesis for AO 33 A- and C2-type fractures. In young patients (< 60 years) postoperative clinical performance was highly satisfying; however, the effects of postoperative hemarthros and anatomic malalignment on the cartilage surface remain major issues for further investigation.

Femur-LISS and distal femoral nail for fixation of distal femoral fractures: are there differences in outcome and complications?

We evaluated the functional and radiologic outcomes after stabilization of distal femoral fractures using the distal femoral nail and a less invasive stabilization system to determine if the new implants are superior to other implants (especially the condylar blade plate) regarding the rates of axial deviation, nonunion, and infection and if one of these new implants (Less Invasive Stabilization System, or distal femoral nail) is superior to the other. Two groups, each with 16 patients, were documented prospectively and the results were compared. To record the findings objectively, the Lysholm-Gillquist score was used. A conversion procedure was done in two patients in the plate group and one patient of the nail group. At the 1-year followup mobility of the knee was on average 110 degrees in the plate group and 103 degrees in the nail group. The Lysholm-Gillquist score did not show any significant differences between the groups. There were clinically relevant varus or outer rotation deviations in three patients in the plate group and two patients in the nail group. The two minimally invasive implants used were good in terms of technique and outcome for treatment of distal femoral fractures and did not differ significantly for epidemiology, fracture type, conversion procedures, infection rate, malalignments, and subjective and objective findings at the 1-year followup. They were also superior to the condylar plate in terms of infection and axial malalignments.

Increase in plasma calcitonin following femoral fracture in rats.

The secretion of calcitonin (CT) has been studied in male rats following a standardized, left femoral fracture after administration of subcutaneous fluanisone and fentanyl citrate anaesthesia. Twenty-five minutes after the fracture, the plasma concentrations of CT were increased by about 20 per cent in young and by about 60 per cent in adult rats compared to prefracture levels of the hormone. Three weeks later, plasma CT had decreased and was not significantly different from prefracture levels. Anaesthesia combined with femoral fracture did not influence plasma calcium significantly, whereas the plasma concentrations of calcium increased in young control rats during 35 minutes of anaesthesia alone. Plasma CT, however, remained unchanged in these control rats in the same period. In rats with a transplanted, CT-secreting, medullary thyroid carcinoma, femoral fracture did not alter the already high plasma concentrations of CT. It is suggested that increase in CT secretion is part of a general response to trauma.

Fixation of distal femoral fractures above total knee arthroplasty utilizing the Less Invasive Stabilization System (L.I.S.S.).

Supracondylar femoral fractures above total knee arthroplasty remain a treatment challenge. Complication rates as high as 30% are associated with both nonoperative and operative treatment. Conventional plate fixation and rigid intramedullary nail fixation has improved the treatment of these fractures. However, problems still exist in the setting of a short distal femoral block and/or significant osteoporosis. Less Invasive Stabilization System (L.I.S.S.) fixation has been utilized for the treatment of supracondylar femoral fractures above total knee arthroplasty. Multiple fixed angle screws give optimal fixation around the femoral component. Advantages appear to include maintenance of distal femoral fixation, low infection, and low need for bone grafting.

Immediate closed antegrade Ender nailing of femoral fractures in polytrauma patients.

Fifty-four trauma patients with 61 femoral fractures stabilized within the first 24 hours of admission by closed antegrade Ender nailing were included in this study. This technique involves the insertion of Ender nails from a portal at the proximal end of the femur through the piriformis fossa. The curved distal ends of the nails were distributed throughout the distal femur to achieve greater purchase in the enlarged medullary canal of the distal fragment. This technique was used in one proximal, 20 midshaft, 37 distal, and three segmental fractures. There were 51 closed fractures, eight Grade I open, and two Grade II open fractures. The average age of the patient was 26 years, and the majority had polytrauma. The operative procedure was well tolerated by this group of patients. Pulmonary care was improved by avoidance of traction and enhanced capability for mobilization. Forty-two patients with 49 femoral fractures were available for complete follow-up. Forty-five fractures healed with the average time to appearance of bridging callus being 33 days, and average time to full union remodeled callus being 5.9 months. There were four nonunions, one delayed union, and eight malunions. There were nail protrusions in 22 cases (19 proximal and three distal). Fourteen patients required a second operation for reimpaction of the protruding nails or premature nail removal. These results were inferior to those obtained with the use of the retrograde Ender nailing technique or the Kuntscher nail. This technique should be used only if other techniques are unavailable or inappropriate, and only for stable, noncomminuted fractures.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment of femoral fractures in the multiply injured patient with thoracic injury.

Early fracture fixation in the multiply injured patient has been shown to reduce morbidity and mortality. This premise recently has been questioned when the multiply injured patient has a pulmonary contusion, and also has a femoral fracture stabilized with a reamed intramedullary nail. This put into question whether early stabilization of femoral fractures, especially with a reamed intramedullary nail, should be performed in patients with a pulmonary contusion. A review of the most recent clinical and animal research was performed to help answer this question. This review has revealed that the incidence of pulmonary failure and adult respiratory distress syndrome in multiply injured patients with thoracic injuries who have femoral fractures treated acutely is less than 3%. The morbidity associated with patients with pulmonary contusions is independent of the treatment of the femoral fracture. No difference in the rate of pulmonary failure is found with reamed nails or plate fixation. The pulmonary failure seems to be secondary to the pulmonary contusion, not to the method of fracture fixation.

Long-term outcome of elastic stable intramedullary fixation (ESIF) of femoral fractures in children.

In 1993 a prospective data collection of all femoral fracture in children below 16 years of age was initiated in 4 hospitals in the Netherlands. Follow-up was at least two years, with the aim to evaluate leg length discrepancies (LLD). Over a period of 10 years, we included 136 patients < 16 years of age with femoral fractures. Seventy-one patients who were treated with an ESIF-(Elastic Stable Intramedullary Fixation) nail were studied: 44 boys and 27 girls, between the ages of 3-16 years, 23 of which had multiple injuries. Five patients had a Ist or IInd degree open fracture. The average length of stay (LOS) of children with an isolated fracture, was 10 days, and in case of multiple injuries: 12 days. Intra-operative complications were: a broken drill in 2 and an open reduction in 6 cases. Two patients with superficial wound infection were successfully treated with antibiotics. Seven patients had knee complaints of the nails, of which 3 had actually been displaced. Three other patients showed displacement of the nails at X-ray, but had no complaints. At six months follow-up, at the time of removal of the nails, 10 patients had a leg length discrepancy (LLD) exceeding 10 mm. Three children had a clinically significant rotational deformity at this time. Two and a half years after injury 6 patients showed a persistent LLD of more than 10 mm. In all 6 the fractured limb was longer. At ten years of follow-up the LLD persisted in 5 patients. One patient had a persistent clinically significant rotational deformity of more than 10 degrees . The advantages of ESIF-nails are: reduction of hospital stay and rapid mobilisation. The disadvantages: two operations (for insertion and removal) with a risk of complication. Long-term follow-up, preferably till growth stops, is necessary to conclude whether persistent lengthening of the fractured limb remains a problem.

Metastasis size in pathologic femoral fractures.

Radiographic assessment was made of metastases in 69 consecutive patients with pathologic femoral fractures. The following variables were considered: width of metastasis, ratio between width of metastasis and bone, axial length of cortical destruction, and proportion of cortical bone destroyed of the circumference. Differences in size of the metastases were not related to location in the femur or histologic type. In 62 of 69 fractures the ratio between width of the metastasis and bone was greater than or equal to 0.60, axial cortical destruction in the neck was greater than or equal to 13 mm and in other parts of the femur greater than or equal to 30 mm, and cortical destruction of the circumference greater than or equal to 50 percent. Prophylactic internal fixation need not be considered for femur metastatic lesions that do not reach these limits.
