Aims. The aim of this study was to assess the safety and clinical outcome of patients with a femoral shaft fracture and a previous complex post-traumatic femoral malunion who were treated with a clamshell osteotomy and fixation with an intramedullary nail (IMN). Methods. The study involved a retrospective analysis of 23 patients. All had a previous, operatively managed, femoral shaft fracture with malunion due to hardware failure. They were treated with a clamshell osteotomy between May 2015 and March 2020. The mean age was 42.6 years (26 to 62) and 15 (65.2%) were male. The mean follow-up was 2.3 years (1 to 5). Details from their medical records were analyzed. Clinical outcomes were assessed using the quality of correction of the deformity, functional recovery, the healing time of the fracture, and complications. Results. The mean length of time between the initial injury and surgery was 4.5 years (3 to 10). The mean operating time was 2.8 hours (2.05 to 4.4)), and the mean blood loss was 850 ml (650 to 1,020). Complications occurred in five patients (21.7%): two with wound necrosis, and three with deep vein thrombosis. The mean coronal deformity was significantly corrected from 17.78° (SD 4.62°) preoperatively to 1.35° (SD 1.72°) postoperatively (p < 0.001), and the mean sagittal deformity was significantly corrected from 20.65° (SD 5.88°) preoperatively to 1.61° (SD 1.95°; p < 0.001) postoperatively. The mean leg length discrepancy was significantly corrected from 3.57 cm (SD 1.27) preoperatively to 1.13 cm (SD 0.76) postoperatively (p < 0.001). All fractures healed at a mean of seven months (4 to 12) postoperatively. The mean Lower Extremity Functional Scale score improved significantly from 45.4 (SD 9.1) preoperatively to 66.2 (SD 5.5) postoperatively (p < 0.001). Partial cortical nonunion in the deformed segment occurred in eight patients (34.8%) and healed at a mean of 2.4 years (2 to 3) postoperatively. Conclusion. A clamshell osteotomy combined with IMN fixation in the treatment of patients with a femoral shaft fracture and a previous post-traumatic femoral malunion achieved excellent outcomes. Partial cortical nonunions in the deformed segment also healed satisfactorily. Cite this article: Bone Joint J 2023;105-B(4):449–454

Intramedullary locking nails have proved to be of considerable advantage when treating complex, comminuted or segmental femoral shaft fractures. We have reviewed 117 patients with 120 femoral shaft fractures treated with the Strasbourg device. These included 20 compound fractures, 13 pathological fractures and two non-unions. Rehabilitation and union rates have been very satisfactory and there have been no serious infections in the series. Comminution of the proximal femur has occurred in six patients and there have been three femoral neck fractures, but all of these have healed without further complications

Fractures of the femoral shaft are generally considered to affect young patients, but we have reviewed 24 cases in patients over 60 years who have been treated by locked nailing, usually by closed methods. Most were women with low-velocity injuries, but despite this, 14 fractures were significantly comminuted. The complication rate was 54% with a peri-operative mortality of 17%. Most complications were the general ones of operating on elderly patients. Specific complications included: fractures below an abnormal hip, proximal fracture related to the nail and poor purchase in the distal femur. In all survivors, the femoral shaft fractures united satisfactorily, and the fixation allowed early mobilisation. The locking nail appears to be an effective method of managing femoral shaft fractures in the elderly patient

The torsion of both femora was evaluated in 110 patients who had been treated by intramedullary nailing for unilateral femoral shaft fractures. The anteversion (AV) angle was measured by ultrasound, using a tilted-transducer technique. True torsional deformity, defined as an AV difference of 15 degrees or more between sides was found in 21 patients, but only eight had complaints related to the deformity. Three patients had reoperations for troublesome external torsional deformities. Of 26 patients with AV differences of 10 degrees to 14 degrees, defined as possible torsional deformity, three had complaints, but none had serious problems. AV differences of up to 29 degrees were observed in symptom-free patients, and no patients with AV differences below 10 degrees had complaints. Static and dynamic nailing showed almost equal tendencies to lead to torsional deformity. We conclude that torsional deformities are usually established during the operation. Many patients tolerate abnormal torsion, but efforts should be made to reduce and stabilise the femoral shaft fracture with an AV difference of less than 15 degrees

In two hospitals, 115 consecutive open femoral shaft fractures were treated by meticulous wound excision and early locked (97) or unlocked (18) intramedullary nailing. All the fractures united; union was delayed in four, three of which required bone grafting. The average range of knee flexion at follow-up was 134 degrees (60 to 148). Five patients had a final range of less than 120 degrees, but three of these improved after manipulation under general anaesthesia. Three patients developed staphylococcal infections and required further surgical treatment. All eventually healed

We studied 47 patients with closed, displaced, diaphyseal fractures of the femur caused by blunt trauma, to determine the incidence of associated knee injuries, particularly of the meniscus. After femoral nailing, all patients had an examination under anaesthesia and an arthroscopy. There were 12 medial meniscal injuries (5 tears) and 13 injuries of the lateral meniscus (8 tears). Ten of the 13 tears were in the posterior third of the meniscus, and two patients had tears of both menisci. Synovitis was common at the meniscal attachments. Complex and radial tears were more common than peripheral or bucket-handle tears. Examination under anaesthesia revealed ligamentous laxity in 23 patients (49%), but meniscal injuries had a similar incidence in knees with and without ligament injury. Femoral shaft fractures are often associated with injuries to the ipsilateral knee, and a high index of suspicion is necessary to identify these lesions

We describe the use of Ender nails for the internal fixation of femoral shaft fractures by a closed technique via the greater trochanter and report the treatment of 100 patients with 106 fractures, of which 88 were reviewed 12 months or more after operation. There was primary union in 85 fractures (96.6%) and significant angulation, rotation or leg length discrepancy in eight (9%). We discuss the principles of management which we have evolved

We reviewed and radiographed 30 skeletally-mature patients after isolated closed femoral shaft fractures in childhood which had been treated conservatively. When the fracture had occurred between the ages of 7 and 13 years, the limb overgrew about 1 cm regardless of sex, upper limb dominance, age, fracture site or configuration. Excessive fracture overlap at the time of injury, but not at union, increased limb overgrowth. Angulation of the fracture remodelled in children injured under 10 years of age, but in older patients this sometimes added to limb shortening. Rotational deformities were minor and gave no symptoms. Treatment of the 7- to 13-year-old patient should aim at 1 cm overlap at union, with correction of angular deformity being more important in children over 10 years of age. This management of fractures will give a maximum leg length discrepancy of 1 cm at skeletal maturity

Over 15 years (1967 to 1982) 140 uncomplicated femoral shaft fractures in children under four years of age were successfully treated using Bryant's traction. Forty of these children were treated after the introduction of the domiciliary management policy in 1976; 13 children were managed at hospital and 27 were managed at home. No significant complications occurred. The advantages to the family, and the safety and economy of domiciliary management lead us to recommend its adoption in favourable cases. Treatment at home relies on an efficient and experienced home nursing service. Possible complications of the injury and treatment with recommendations to prevent them are discussed

Ninety-eight fractures of the shaft of the femur were seen in one unit over the two years 1974 and 1975, and the results have been assessed in sixty-nine. Of these, thirty-eight were treated by skeletal traction in a Thomas's splint followed by skin traction, and thirty-one by skeletal traction followed by a cast-brace. The technique of application is described in some detail. The average time for application of the cast-brace was six weeks after the injury, the time in hospital eight weeks and the time till removal fifteen weeks. The patients selected for a cast-brace were in hospital for just over half the time of the others and their fractures on average united more quickly, though with some trouble from angulation of fractures of the uppermost third of the shaft. It is concluded that when used with all the judgment and skill it demands, the cast-brace method is a great advance in conservative treatment.

We report the use of elastic stable intramedullary nailing (ESIN) in 123 fractures of the femoral shaft in children. Flexible rods are introduced through the distal metaphyseal area, and the aim is to develop bridging callus. Early weight-bearing is possible and is recommended. There was one case of bone infection and no delayed union. Complications were minimal, the most common being minor skin ulceration caused by the ends of the rods. A surprising feature was the low incidence of growth changes, with a mean lengthening of only 1.2 mm after an average follow-up of 22 months. Compared with conservative treatment, ESIN obviates the need for prolonged bed rest and is thus particularly advantageous for treating children.

From a series of 190 consecutive fractures of the shaft of the femur treated by closed Kuntscher nailing, 32 of the more severely comminuted have been studied to determine whether treatment by closed nailing was justified. Radiological criteria were used to divide them into 19 who were moderately comminuted and 13 grossly so. Twenty-four patients were less than 21 years of age and 19 patients had 40 significant associated injuries. Fifteen fractures were nailed on the day of injury, and complications were few. Nineteen patients had a supplementary cast-brace and all those who had been employed returned to work. Twelve patients had shortening of up to two centimetres and two had three centimetres; four had mild rotational deformities; seven had mild restriction of knee flexion; and two had delayed union. There were no infections. The advantages of this technique include a negligible risk of infection and rapid stabilisation of even grossly comminuted fractures, thus facilitating management of other injuries. The 44 per cent incidence of shortening is counterbalanced by early mobilisation and rapid return of knee function. It is concluded that when proper equipment and expertise are available then closed nailing is the treatment of choice for severely comminuted fractures of the femoral shaft.

The treatment of fractures of the femoral shaft by traction may delay union and produce stiffness of the knee. The technique of Perkins' method is described and the results reported in 50 cases. All patients had at least 120 degrees of flexion of the knee when traction was discontinued, and 47 patients were considered to have clinical and radiological union of the fracture by 12 weeks. The main complications of the method was loosening of the Denham pin or infection of the pin-track in the proximal tibia. It is suggested that Perkins' traction is an excellent form of treatment for fractures of the femoral shaft, and has several advantages over other forms of traction.

The off-loading characteristics of the cast-braces of 30 patients with fractures of the shaft of the femur have been investigated, during axial loading, using strain-gauge transducers. These were applied at the level of the fracture, where the cast was circumferentially split, and to the hinges of the brace at the knee. They measured the load transferred between the two portions of the thigh cast, and between the thigh cast as a whole and the below-knee cast; by subtraction from the total load on the limb, the skeletal force at the fracture level and at the knee could be calculated. In all patients there was an increase in the fracture load as union progressed which was thought to be due to physiological feedback mechanism from the fracture site. The load carried by the two portions of the thigh cast and by the thigh cast as a whole was proportionately high at first and stabilised at an average of 35 per cent of body weight.

We reviewed 28 children with unilateral middle-third fractures of the femoral shaft who had an angular deformity after union of 10 degrees to 26 degrees. At an average follow-up of 45 months (20 to 66), we measured remodelling of the proximal physis, the distal physis and the femoral shaft. The average correction was 85% of the initial deformity. We found that 74% of correction occurred at the physes and only 26% at the fracture site. Neither the direction nor the magnitude of the angulation much influenced the degree of remodelling. Younger children remodelled only a little better than older children. We conclude that in children under 13 years of age, malunion of as much as 25 degrees in any plane will remodel enough to give normal alignment of the joint surfaces.

One hundred and two fractures of the femoral shaft, including eighteen pathological fractures, in 100 patients were internally fixed by closed Kuntscher nailing. Sixty-eight fractures resulted from motor vehicle accidents; ten were compound. Seventy-five patients were under the age of thirty years and thirty-four had multiple injuries. Sixty-nine fractures were nailed on the day of the accident and the operative technique is described. Complications during and after operations were few. Fifty-eight patients left hospital within four weeks and 77% of those working returned to work in less than four months. There were no wound or bone infections. The results are discussed and it is concluded that, with the correct equipment and careful attention to detail, closed nailing is a straightforward procedure with few complications. Advantages include the wide range of fractures that can be nailed, the short hospitalisation, the rapid return of function to the knee, the early return to work and the absence of infection.

Elastic stable intramedullary nailing (ESIN) is generally acknowledged to be the treatment of choice for displaced diaphyseal femoral fractures in children over the age of three years, although complication rates of up to 50% are described. Pre-bending the nails is recommended, but there are no published data to support this. Using synthetic bones and a standardised simulated fracture, we performed biomechanical testing to determine the influence on the stability of the fracture of pre-bending the nails before implantation. Standard ESIN was performed on 24 synthetic femoral models with a spiral fracture. In eight cases the nails were inserted without any pre-bending, in a further eight cases they were pre-bent to 30° and in the last group of eight cases they were pre-bent to 60°. Mechanical testing revealed that pre-bending to 60° produced a significant increase in the stiffness or stability of the fracture. Pre-bending to 60° showed a significant positive influence on the stiffness compared with unbent nails. Pre-bending to 30° improved stiffness only slightly.

These findings validate the recommendations for pre-bending, but the degree of pre-bend should exceed 30°. Adopting higher degrees of pre-bending should improve stability in spiral fractures and reduce the complications of varus deformity and shortening.
