We report retrospective and prospective studies to identify the causes of fracture of the femoral neck associated with femoral shaft nailing on the same side. Of a total of 14 neck fractures in a series of 152 shaft nailings, eight were not visible on the initial pelvic radiographs. We used CT scans before and after operation, and fluoroscopy during the procedure in our prospective series, and reviewed abdominal CT scans retrospectively with the window set to bone level. Six of the eight undisplaced fractures were shown to have been present before operation, but two were iatrogenic. We recommend the preoperative use of CT scans of the femoral neck in high-risk patients such as those with associated fractures of the acetabulum, the distal femur or the patella. Early diagnosis will allow better general management and early fixation of the neck fracture

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

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

We have analysed the initial displacement and the retention of position after reduction of 192 spiral fractures of the tibial shaft. In fractures with an initial lateral displacement of one half the width of the shaft or more, successful retention of position after the primary closed reduction was achieved in only 18%. The direction of displacement between the tibial fragments showed little variation; the proximal fragment was always medial and anterior to the distal. This resulted in an increased space between the proximal tibial fragment and the shaft of the fibula in the plane of the interosseous membrane. There was a strong correlation between the initial displacement and the initial shortening. No evidence of a posterior soft-tissue hinge, able to facilitate closed reduction, could be found. Consequently, in treating severely displaced spiral fractures, open reduction and internal fixation or a few weeks' initial calcaneal traction seem to be the rational alternatives

1. The combination of femoral shaft fracture with dislocation of the hip in the same limb has been recorded in eighty-one patients since 1823. 2. A further fourteen cases are reported. 3. In over half the cases the hip dislocation was diagnosed late or not at all, and this error has occurred more often in modern times. The reasons for this are outlined. 4. The diagnostic physical signs of hip dislocation in the presence of a femoral shaft fracture are described. 5. The mechanism, sequels and treatment of this combined injury are discussed

Hindfoot (subtalar) movement and disability after fracture of the tibial shaft have been studied. One hundred patients with soundly healed fractures of the tibial shaft treated by immobilisation in a long leg plaster cast were examined at least one year after the fracture had healed. Subtalar movement was accurately measured by a special technique and the patients were questioned specifically about any disability associated with their hindfoot. Subtalar movement was limited to some degree in 72% of patients. Forty-three per cent of patients complained of symptoms related to their subtalar joint and 12% found these symptoms troublesome

Twenty-six children conservatively treated for fracture of the femoral shaft have been reviewed with regard to differences in limb length seven to ten years after the injury. In nine patients the clinical measurements were checked against radiographic measurements of both femora and tibiae. The following conclusions were reached. Nearly two-thirds of the patients had overgrowth of the femur of 10 millimetres or more. Shortening of 15 to 20 millimetres at the fracture site was well compensated for by accelerated growth. Growth acceleration seemed to take place during the healing period and the difference at the end of healing was permanent. Overgrowth was promoted by comminuted and long oblique fractures and by overriding of the fracture ends, but was not influenced by the age at fracture, the duration of treatment or the level of fracture of the shaft. Growth of the tibia was not affected by the femoral fracture

A study was made of the mechanics of blood-bearing in a series of patients treated with a cast-brace for fracture of the distal femur. Knee hinges incorporating strain-gauges, a simple force-plate on the floor and a standardised weight-bearing test were used to record axial loads through the cast-brace itself and through the fracture during the phases of healing. The cast-brace carried loads of only 10 to 20 per cent of body weight and functioned mainly as an antibuckling hinged tube. Patterns of weight-bearing recovery showed that the fracture itself limited loads to safe levels. A measure of the recovery of strength at the fracture was determined and termed the "fracture load index". Graphs obtained in this way demonstrated four biomechanical phases of bony union which correlated well with the stages of clinical healing. The clinical application of these results have led to improvements in the design of braces and the use of a cylinder cast-brace for fractures of the distal half of the femoral shaft and of a new type of brace with a hinge at the hip attached to the thigh cast for fractures of the proximal shaft. A simple clinical test is described by which it is possible to monitor the healing of fractures in cast-braces

1. The frequency of variable degrees of ischaemia of soft tissue in closed tibial and fibular shaft fractures is emphasised. 2. Two cases with ischaemia of calf musculature are described. 3. A follow-up study of 100 cases of closed tibial shaft fractures is analysed; ten patients were found to be affected. 4. The anatomical and pathological changes are discussed. 5. A plea is made for early surgical exploration in cases manifesting signs of ischaemia

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

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

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

1. The results in 211 fractures of the shaft of the femur in adults treated by internal fixation have been reviewed. 2. A comparison has been made between the effects of early internal fixation within the first six days of injury and delayed fixation. 3. Eighty-five fractures treated by early fixation gave a rate of non-union of 23 per cent; in 126 fractures treated by delayed fixation the rate was 0·8 per cent. 4. Delayed operation is therefore advocated for the majority of femoral shaft fractures for which internal fixation is indicated

1. A series of twenty-one cases of re-fracture of the femoral shaft has been examined and analysed. 2. Liability to re-fracture may be increased if the original injury is caused by great violence, but it does not seem to be affected by the method of primary treatment. 3. Over 60 per cent of the re-fractures were avoidable. In some, re-fracture was caused by premature institution of vigorous mobilisation; in others, warning cracks were visible on radiographs before re-fracture. 4. In the remaining patients re-fracture appears to be unpredictable and unavoidable. 5. Re-fracture is best treated by the simplest methods

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

Ten uncemented total hip replacements were performed in 1975 using an implant in which the cobalt-chrome femoral stem was coated to give a porous surface. In all but one case a high-density polyethylene head was used. The radiological changes in the upper femoral shafts were assessed between three and nine years later. Seven showed extensive stress-relieving changes, loss of calcar, stress fractures at the root of the lesser trochanter with subsequent detachment, and osteoporosis followed by avulsion of the greater trochanter. In these seven patients the lower part of the stem appeared to be soundly embedded, although in only one was there evidence of bony incorporation. It is suggested that if the fixation of a fully coated implant of this sort remains sound, gross atrophy of the upper femoral shaft develops after five years. This atrophy, associated with an implant which can be removed only at the expense of further bone destruction, presents substantial problems if revision is needed

We randomised prospectively 44 patients with fractures of the shaft of the humerus to open reduction and internal fixation by either an intramedullary nail (IMN) or a dynamic compression plate (DCP). Patients were followed up for a minimum of six months. There were no significant differences in the function of the shoulder and elbow, as determined by the American Shoulder and Elbow Surgeons’ score, the visual analogue pain score, range of movement, or the time taken to return to normal activity. There was a single case of shoulder impingement in the DCP group and six in the IMN group. Of these six, five occurred after antegrade insertion of an IMN. In the DCP group three patients developed complications, compared with 13 in the IMN group. We had to perform secondary surgery on seven patients in the IMN group, but on only one in the DCP group (p = 0.016). Our findings suggest that open reduction and internal fixation with a DCP remains the best treatment for unstable fractures of the shaft of the humerus. Fixation by IMN may be indicated for specific situations, but is technically more demanding and has a higher rate of complications

One hundred patients who had sustained a fracture of the tibial shaft and had been treated by internal fixation were reviewed to obtain information on residual ankle and subtalar disability. This study reinforces the belief that early mobilisation of patients with tibial shaft fractures does help to preserve subtalar movement

1. A series of 154 patients with 156 femoral shaft fractures treated during a three and a half year period is reviewed. Fifty-four fractures were treated by closed intramedullary nailing, sixty-four by open intramedullary nailing and thirty-eight by conservative methods. 2. All the patients had fresh fractures of a similar degree of severity. Seventy-eight per cent of the fractures were sustained in traffic accidents, and 21 per cent were compound. 3. The technique of closed intramedullary nailing is described in detail. The importance of a complete and faultless armamentarium and a high-quality image intensifier is emphasised. 4. All fractures united within twelve months after the accident. 5. The functional results were assessed upon the basis of walking ability and return to work. Nailed fractures did better than conservatively treated ones, and closed nailing was slightly superior to open nailing. At twelve months after the injury all patients treated by closed nailing walked without a stick, compared with 96 per cent of the cases treated by open nailing and 81 per cent of the conservatively treated patients. The same trend was noted regarding return to work. 6. The benefit of intramedullary nailing was partly dependent on the severity of the fracture and the age of the patient. The most gratifying results of nailing were obtained in patients over thirty-five years of age with severe fractures. 7. Osteitis occurred in one case treated by closed nailing, and low grade wound infections in five cases, representing an overall infection rate of 3·8 per cent. 8. Seventy-four per cent of the patients were examined one to four years after the fracture. There was less angular deformity and more rotational deformity in the nailed than in the conservatively treated fractures. The tip of the nail gave slight discomfort in the trochanteric area in one patient in three. Residual joint stiffness was infrequent in the nailed cases as compared to the conservatively treated ones. 9. The indications for closed intramedullary nailing of femoral shaft fractures are outlined

The management of closed fractures of the humerus with an associated nerve palsy remains controversial. With very little written about this injury in children, we present the case of a three-year-old child with a closed humeral shaft fracture in whom surgical exploration and reconstruction of the radial nerve with a sural nerve graft was performed three months after injury. The child regained full function. To the best of our knowledge, this is the first such case to be reported in the English literature
