Subtrochanteric femoral fractures.

Femoral fractures in the subtrochanteric and proximal shaft regions require special management because of the great stresses inflicted on the area. Stability is best achieved with intramedullary fixation when there is adequate control of both proximal and distal fragments. Intertrochanteric fractures with small subtrochanteric components can often be adequately fixed with strong nail plate or screw plate devices. When the major fracture is subtrochanteric, an intramedullary device should be used to permit stability of the bone by impaction. Experience with a special device composed of an intramedullary rod and triflanged nail indicates that this appliance performs well in the fixation of subtrochanteric fractures.

Midshaft femoral fracture, concomitant ipsilateral hip joint injury, and disruption of the knee extensor mechanism: a unique triad of dashboard injury.

Our experience with 10 patients who suffered midshaft fractures of the femur and injuries to their ipsilateral hips has resulted in a treatment protocol that we believe can avoid unnecessary complications. The surgical protocol is a three-stage procedure based on (1) intramedullary nailing of the femur with interlocking for preserving the anatomic length and rotation of the femur; (2) treatment of the hip joint injury by means of open reduction and internal fixation of the acetabular fracture and/or reduction and fixation of the fractured femoral neck; and (3) repair of the extensor mechanism. Eight patients received this treatment and had fast recoveries. Union of the femoral fracture and full range of motion of the knee joint were observed within 3 months. In contrast, two patients who had received different surgical treatment had incomplete functional recoveries. This study offers a treatment protocol for ipsilateral disruption of the extensor mechanism, hip joint injury, and midshaft fracture of the femur in the multiply injured patient that can achieve full recovery with no complications. This relatively rare combination of injuries is definitely worthy of special attention.

Total knee arthroplasty following prior distal femoral fracture.

BACKGROUND: Femoral fracture may predispose the knee to the development of post-traumatic arthritis by either a direct intra-articular injury or residual limb malalignment. Malunion, intra-articular osseous defects, limb malalignment, retained internal fixation devices, and compromised surrounding soft tissues may in turn affect the outcome of total knee arthroplasty (TKA) in these patients. The aim of our study was to evaluate the result of TKA in patients with previous distal femoral fracture. METHODS: The results of 48 cemented condylar total knee arthroplasties, performed between 1980 to 1998, in 47 patients with a previous distal femoral fracture were reviewed. There were 37 females and 10 males with an average age of 65 years (range, 19-84 years). Follow-up averaged 6.2 years (range, 2-16 years). No patients were lost to follow-up. RESULTS: At the time of arthroplasty a femoral fracture non-union was present in three knees, all of which were treated with a long stem cemented femoral component and bone grafting. Malunion, defined as angulation greater than 10 degrees in the coronal plain or greater than 15 degrees in the sagittal plain, was present in 21 knees. Of these, six underwent distal femoral osteotomy during TKA. In the remaining 15 patients, with a malunion, the deformity was addressed by alterations in the orientation and location of bone resection. Other procedures were commonly needed at the time of arthroplasty and included: lateral retinacular release (22 knees), extensor mechanism realignment (eight knees), and collateral ligament reconstruction (two knees). The mean pre-operative Knee Society Scores were 40 (range, 0-80) for pain and 48 (range, 0-100) for function and improved significantly to a mean of 84 (range, 37-99) and 66 (range, 0-100) points, respectively, at the latest follow-up (P<0.001). The knee arc of motion improved from a pre-operative mean of 83-99 degrees at the latest follow-up (P<0.004). Post-operative manipulation under anesthesia for poor motion was carried out in four knees. Two knees had aseptic loosening that required subsequent revisions. Three knees developed deep infection which was treated with debridement and retention of components in one knee, arthrodesis in another, and eventual amputation in one knee. CONCLUSIONS: Significant improvement in function and relief of pain is seen in the vast majority of patients with previous distal femoral fractures undergoing subsequent TKA. However, these patients are at increased risk for restricted motion and perioperative complications following TKA. Special efforts to preserve the vascularity of the skin and subcutaneous tissues, restore limb alignment, ensure correct component positioning, and achieve soft tissue balance may help minimize the problems identified in this study.

Co-ordinated multidisciplinary approaches for inpatient rehabilitation of older patients with proximal femoral fractures.

BACKGROUND: Hip fracture is a major cause of morbidity in older people and its impact, both on the individual and to society, is substantial. OBJECTIVES: To examine the effects of co-ordinated multidisciplinary inpatient rehabilitation, compared with usual orthopaedic care, for older patients with hip fracture. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group trials register, Medline (up to April 1998), and reference lists of published papers and books. We also contacted colleagues and trialists. SELECTION CRITERIA: Randomised and quasi-randomised trials of postsurgical care using specialised rehabilitation of mainly older patients (aged 65 years or over) with hip fracture. DATA COLLECTION AND ANALYSIS: Trial assignment to included, excluded and awaiting assessment categories, was by consensus. Two reviewers independently assessed trial quality and extracted data. Limited additional information was sought from most trialists. As well as pooling of data from primary outcomes, supplementary analyses were performed to combine clinically relevant outcomes and investigate possible explanatory factors. MAIN RESULTS: In this minor update, one new trial is identified and has been placed in "studies awaiting assessment". Of another three trials previously pending assessment, one has now been excluded. The five included trials involved 1068 patients. The combined outcomes of death or requiring institutional care at final follow-up showed no significant difference between intervention and control groups (Peto odds ratio 0.92; 95% confidence interval 0.71 to 1.18). There was considerable heterogeneity in length of stay and cost data. Using death and deterioration in function as a further combined outcome variable yielded a Peto odds ratio of 0.83 (95% confidence interval 0.64 to 1. 07). This should be interpreted with caution due to heterogeneity. No quality of life measures were reported and the two trials investigating carer burden showed no detrimental effect from the intervention. The review update did not result in any new data for these outcomes. REVIEWER'S CONCLUSIONS: The trials reviewed had different aims, interventions and outcomes. As a consequence, results were heterogeneous and the question of effectiveness of different types of co-ordinated inpatient rehabilitation after hip fracture cannot be answered conclusively. There is a trend to effectiveness when combined outcome variables (death and institutional care, death and deterioration in function) are considered. Future trials of postsurgical care involving inpatient rehabilitation, or other models such as 'early supported discharge' and 'hospital at home' schemes, should aim to establish both effectiveness and cost effectiveness of multidisciplinary rehabilitation overall, rather than attempt to evaluate its components.

Küntscher nailing in the treatment of femoral fractures in children. Is it completely contraindicated?

Seventeen children between the ages of 6 and 12 years with fractured femoral shafts were treated by Küntscher nailing. They were followed up clinically and radiographically to ascertain if nailing had any long term adverse effects. The following radiographic parameters were considered: --valgus, varus angle; --distance between lesser trochanter and acetabulum; --width of the neck of the femur; --distance between greater trochanter and acetabulum; --intertrochanteric distance. On analysing the results it was found that Küntscher nailing did not give rise to any adverse effects provided it is carried out after 8-9 years of age.

Distal femoral fractures.

Distal femoral fractures may be treated by operative or nonoperative methods. There is no single surgical implant that can be used for all distal femoral fractures. Implant selection is determined by fracture pattern, patient age, bone density, and other injuries that the patient may have sustained. Rewarding results may be obtained with operative fracture intervention when appropriate patient and implant selection is made and the surgeon demonstrates meticulous skill and sound judgment.

Minimally invasive fracture stabilization of distal femoral fractures with the LISS: a prospective multicenter study. Results of a clinical study with special emphasis on difficult cases.

The LISS-DF (Less invasive stabilization system-distal femur) is a new type of implant system for the treatment of distal femoral fractures according to the principles of "Minimally Invasive Surgery". A plate, pre-contoured to the anatomy, is inserted through a minimally invasive incision into the epiperiosteal space by means of an aiming device after indirect, closed fracture reduction. The implant is stabilized by insertion of screws which lock into the plate holes and prevent tilting. This is performed with the aid of an aiming device and through stab incisions. It is not necessary for a large area to be exposed at the fracture site. As part of an AO prospective multicenter study, the new system was applied to 112 patients with 116 fractures. The time to follow-up was on average 13.7 months (minimum 7 months, maximum 33 months). Fractures treated were distal femoral shaft and supracondylar femoral fractures. Eight patients died during the study of causes unrelated to the implant. Of the remaining 104 patients with 107 fractures, 96 patients with 99 fractures were available for complete follow-up (93% follow-up rate). In 90% of all cases treated and followed up, the fracture had consolidated during the period of observation. Twenty-three revision operations were necessary in 21 patients. In two cases, implant failure occurred as the result of a pseudarthrosis. The complications can be attributed in nearly all cases to the severity of the trauma and/or a lack of experience when applying the new style implant to a wider range of indications. The results of the study show that with a sound knowledge of the operative technique and careful preoperative planning this system represents an excellent, safe procedure for the treatment of almost all distal femoral fracture types including periprosthetic fractures of the distal femur. There is generally no need for primary cancellous bone grafting.

Flexible intramedullary fixation of femoral fractures.

Fifty femoral fractures in 47 patients were treated by the insertion of flexible intramedullary Ender rods and observed until fracture healing was complete. Both condylocephalic and trochanteric approaches were used with a preference for the latter when biomechanically feasible. The fractures ranged from the intertrochanteric-subtrochanteric junction to the supracondylar area of the femur. This technique can be used to treat fractures unsuited for conventional rods. The system is relatively uncomplicated, the technique atraumatic. Healing is generally rapid. There were no non-unions, infections, surgical deaths, or significant residual deformities.

The versatility of the contoured AO plate as a mode of fixation for proximal femoral fractures.

Proximal femoral fractures, especially in young adults, usually are high-energy injuries associated with severe comminution. Presently available fixation devices such as the blade plate and DHS are difficult to apply in comminuted cases, their application requires the use of an image intensifier, and their versatility is limited. This report describes the use of the AO plate molded according to the proximal femoral anatomy in 21 cases (seven subtrochanteric and 14 trochanteric fractures) in which high-energy injuries were sustained. Eleven cases were primarily bone grafted. Postoperative mobilization was started by an average of 5.4 weeks. All cases united by an average of 3.2 months. There were six excellent, ten good, three fair, and one poor result (one patient died). This method was found to be superior to conventional devices as it offers more versatility in placement of screws and plate contouring. The inventory of implants is also reduced, and there is no need for specialized instruments, a significant factor in Third World countries.

Serum 1alpha,25-dihydroxyvitamin D3 accumulates into the fracture callus during rat femoral fracture healing.

1,25-dihydroxyvitamin D3 (1,25(OH)2D3) is thought to be an important systemic factor in the fracture repair process, but the mechanism of action of 1,25(OH)2D3 has not been clearly defined. In this study, the role of 1,25(OH)2D3 in the fracture repair process was analyzed in a rat closed femoral fracture model. The plasma concentration of 1,25(OH)2D3 rapidly decreased on day 3 and continued to decrease to 10 days after fracture. We assessed whether this decrease was based on the accelerated degradation or retardation of the synthesis rate of 1,25(OH)2D3, from 25(OH)D3. After radiolabeled 3H-1,25(OH)2D3 or 3H-25(OH)D3 was injected i.v. into fractured or control (unfractured) rats, the concentrations of 25(OH)D3 and 1,25(OH)2D3 metabolites were measured by HPLC. The plasma concentrations of these radiolabeled metabolites in fractured group were similar to those in control rats early after operation. However, radioactivity in the femurs of fractured rats was higher than that of the control group. Furthermore, the radioactivity was concentrated in the callus of the fractured group analyzed by autoradiography. 1,25(OH)2D3 receptor gene expression was detected early after fracture and, additionally, both in the soft and hard callus on days 7 and 13 after fracture. These results showed that the rapid disappearance of 1,25(OH)2D3 in the early stages after fracture was not due to either increased degradation or decreased synthesis of 1,25(OH)2D3, but rather to increased consumption. Further, these results suggest the possibility that plasma 1,25(OH)2D3 becomes localized in the callus and may regulate cellular events in the process of fracture healing.

External fixation of pediatric femoral fractures.

Fifteen pediatric femoral fractures in 14 patients were treated with external fixation using the EBI Orthofix unilateral external fixator. The average patient age was 8.5 years (range, 3-13 years). There were 7 children with multiple injuries and 7 with isolated fractures. The average duration in the fixator was 63 days; average followup was 34 months. All 15 fractures healed without additional operative intervention. Average angulation at the fracture site was 4.4 degrees in the anteroposterior plane (range, 0 degrees-10 degrees) and 4.6 degrees in the lateral plane (range, 0 degrees-11 degrees). There were 5 pin tract infections, all of which resolved with systemic antibiotics. There was 1 case of refracture in a boy with muscular dystrophy. Ten patients had clinically equal leg lengths, 3 patients had < 1 cm of inequality, and 1 patient had a 1.5 cm discrepancy. External fixation is a well-proven technique for managing pediatric femoral fractures in the child with multiple injuries. It is also an effective means of treating isolated femoral fractures in the pediatric population.

[Osteosynthesis of proximal femoral fractures using short proximal femoral nails].

PURPOSE OF THE STUDY: A group of 147 patients with proximal femoral fractures treated with the use of the proximal femoral nail, manufactured by the Synthes company, in the period between October 1997 and June 2001 were retrospectively evaluated. MATERIAL: The group of 147 patients whose average age was 69 years consisted of 59 men (average age, 59 years) and 88 women (average age, 75 years). The most frequent fracture occurring in 54% of the patients was an unstable pertrochanteric fracture (Kyle III); persubtrochanteric and subtrochanteric fractures were treated in 27% and 19% of the patients, respectively. METHODS: In 1997, a new implant, the proximal femoral nail manufactured by the Synthes company (PFN), was introduced in the Czech Republic. In addition to all advantages of a nail to be implanted intramedullary, it has several other favorable characteristics: its length is 240 mm, pre-drillings is not necessary, it can be dynamically locked, it has a high rotation stability, and mechanical stress concentration on the implant-bone interface is low. This evaluation is based on the type of fracture, the duration of healing, the duration of surgery and X-ray exposure. RESULTS: The patients were followed up at 6 months, 3, 6 and 12 months, and once a year. The fracture healed in the anatomical position by 6 months in 95% of them. The average operative time was 56 min and X-ray exposure lasted on average 1 min. We recorded 14 intra-operative complications in nine patients, which included incomplete reduction in four cases, fixation in distraction in two, incorrect length of screws in one, fracture at the site of distal locking in two and incorrect insertion of femoral neck screws in five cases. Early post-operative complication involved seven cases of hematoma in the operation wound with the necessity to re-operate in five cases. Late complications occurred in two patients and included pseudoarthrosis and necrosis of the femoral head after healing. Most of the complications were found in subtrochanteric fractures. DISCUSSION: The treatment of unstable fractures of the proximal femur is still associated with some failures. The reasons are: disregard for biomechanics, overestimation of the potentials of new surgical techniques or new implants or poor adherence to established procedures. PFN is a novel, modern implant based on experience with the gamma nail. Since relevant literature data are very few, any comparison of our results is very difficult. The lower average age of our group was due to the intentional selection of our patients for this type of surgery. CONCLUSIONS: PFN is an excellent implant for the treatment of unstable fractures of the proximal femur. The terms of successful outcome include a good understanding of fracture biomechanics, correct indication and exactly performed osteosynthesis.
