The management of radial nerve palsy associated with fractures of the shaft of the humerus has been disputed for several decades. This study has systematically reviewed the published evidence and developed an algorithm to guide management. We searched web-based databases for studies published in the past 40 years and identified further pages through manual searches of the bibliography in papers identified electronically. Of 391 papers identified initially, encompassing a total of 1045 patients with radial nerve palsy, 35 papers met all our criteria for eligibility. Meticulous extraction of the data was carried out according to a preset protocol. The overall prevalence of radial nerve palsy after fracture of the shaft of the humerus in 21 papers was 11.8% (532 palsies in 4517 fractures). Fractures of the middle and middle-distal parts of the shaft had a significantly higher association with radial nerve palsy than those in other parts. Transverse and spiral fractures were more likely to be associated with radial nerve palsy than oblique and comminuted patterns of fracture (p < 0.001). The overall rate of recovery was 88.1% (921 of 1045), with spontaneous recovery reaching 70.7% (411 of 581) in patients treated conservatively. There was no significant difference in the final results when comparing groups which were initially managed expectantly with those explored early, suggesting that the initial expectant treatment did not affect the extent of nerve recovery adversely and would avoid many unnecessary operations. A treatment algorithm for the management of radial nerve palsy associated with fracture of the shaft of the humerus is recommended by the authors

Aims. The purpose of this study was to determine the weightbearing practice of operatively managed fragility fractures in the setting of publically funded health services in the UK and Ireland. Methods. The Fragility Fracture Postoperative Mobilisation (FFPOM) multicentre audit included all patients aged 60 years and older undergoing surgery for a fragility fracture of the lower limb between 1 January 2019 and 30 June 2019, and 1 February 2021 and 14 March 2021. Fractures arising from high-energy transfer trauma, patients with multiple injuries, and those associated with metastatic deposits or infection were excluded. We analyzed this patient cohort to determine adherence to the British Orthopaedic Association Standard, “all surgery in the frail patient should be performed to allow full weight-bearing for activities required for daily living”. Results. A total of 19,557 patients (mean age 82 years (SD 9), 16,241 having a hip fracture) were included. Overall, 16,614 patients (85.0%) were instructed to perform weightbearing where required for daily living immediately postoperatively (15,543 (95.7%) hip fracture and 1,071 (32.3%) non-hip fracture patients). The median length of stay was 12.2 days (interquartile range (IQR) 7.9 to 20.0) (12.6 days (IQR 8.2 to 20.4) for hip fracture and 10.3 days (IQR 5.5 to 18.7) for non-hip fracture patients). Conclusion. Non-hip fracture patients experienced more postoperative weightbearing restrictions, although they had a shorter hospital stay. Patients sustaining fractures of the shaft and distal femur had a longer median length of stay than demographically similar patients who received hip fracture surgery. We have shown a significant disparity in weightbearing restrictions placed on patients with fragility fractures, despite the publication of a national guideline. Surgeons intentionally restrict postoperative weightbearing in the majority of non-hip fractures, yet are content with unrestricted weightbearing following operations for hip fractures.

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

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

1. A method of medullary nailing of fractures of the shaft of the tibia with a straight clover-leaf nail of large calibre is described. The nail is introduced, without exposure of the fracture, through the deep infrapatellar bursa. No external splint is used and the patient is usually allowed to walk as soon as the wound is healed. The technique is essentially that of Küntscher. 2. The results obtained in the first fifty patients so treated are described. The average period of absence from work for those twenty-five whose treatment was satisfactory was eleven weeks. There were no cases of sepsis or non-union; the only difficulties encountered were mechanical ones

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

We have systematically reviewed the effect of alternative methods of stabilisation of open tibial fractures on the rates of reoperation, and the secondary outcomes of nonunion, deep and superficial infection, failure of the implant and malunion by the analysis of 799 citations on the subject, identified from computerised databases. Although 68 proved to be potentially eligible, only eight met all criteria for inclusion. Three investigators independently graded the quality of each study and extracted the relevant data.

One study (n = 56 patients) suggested that the use of external fixators significantly decreased the requirement for reoperation when compared with fixation with plates. The use of unreamed nails, compared with external fixators (five studies, n = 396 patients), reduced the risk of reoperation, malunion and superficial infection.

Comparison of reamed with unreamed nails showed a reduced risk of reoperation (two studies, n = 132) with the reamed technique. An indirect comparison between reamed nails and external fixators also showed a reduced risk of reoperation (two studies) when using nails.

We have identified compelling evidence that unreamed nails reduced the incidence of reoperations, superficial infections and malunions, when compared with external fixators. The relative merits of reamed versus unreamed nails in the treatment of open tibial fractures remain uncertain.

1. A brief summary is given of the literature on patients with a dislocated hip and a fractured femur on the same side.

2. One further patient is reported, treated by closed reduction of the hip and the fracture.

3. A warning is given on the frequency with which the dislocation is not diagnosed in this double injury.

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

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. Three cases of injury to the femoro-popliteal artery complicating fracture of the femoral shaft are described. 2. In all three cases restoration of peripheral circulation by arterial repair carried out within ten hours of injury succeeded in saving the limb from permanent damage. 3. The importance of adequate resuscitation, early diagnosis and early adequate surgical intervention is stressed. 4. The mechanism of injury and the clinical features of help in early diagnosis are discussed. 5. The place of internal fixation of the femoral fragments is discussed and its advantages and disadvantages are compared with those of treatment by skeletal or skin traction

Aims. The primary aim of this study was to develop a reliable, effective radiological score to assess the healing of humeral shaft fractures, the Radiographic Union Score for HUmeral fractures (RUSHU). The secondary aim was to assess whether the six-week RUSHU was predictive of nonunion at six months after the injury. Patients and Methods. Initially, 20 patients with radiographs six weeks following a humeral shaft fracture were selected at random from a trauma database and scored by three observers, based on the Radiographic Union Scale for Tibial fractures system. After refinement of the RUSHU criteria, a second group of 60 patients with radiographs six weeks after injury, 40 with fractures that united and 20 with fractures that developed nonunion, were scored by two blinded observers. Results. After refinement, the interobserver intraclass correlation coefficient (ICC) was 0.79 (95% confidence interval (CI) 0.67 to 0.87), indicating substantial agreement. At six weeks after injury, patients whose fractures united had a significantly higher median score than those who developed nonunion (10 vs 7; p < 0.001). A receiver operating characteristic curve determined that a RUSHU cut-off of < 8 was predictive of nonunion (area under the curve = 0.84, 95% CI 0.74 to 0.94). The sensitivity was 75% and specificity 80% with a positive predictive value (PPV) of 65% and a negative predictive value of 86%. Patients with a RUSHU < 8 (n = 23) were more likely to develop nonunion than those with a RUSHU ≥ 8 (n = 37, odds ratio 12.0, 95% CI 3.4 to 42.9). Based on a PPV of 65%, if all patients with a RUSHU < 8 underwent fixation, the number of procedures needed to avoid one nonunion would be 1.5. Conclusion. The RUSHU is reliable and effective in identifying patients at risk of nonunion of a humeral shaft fracture at six weeks after injury. This tool requires external validation but could potentially reduce the morbidity associated with delayed treatment of an established nonunion. Cite this article: Bone Joint J 2019;101-B:1300–1306

We analysed retrospectively the risk factors leading to femoral overgrowth after flexible intramedullary nailing in 43 children (mean age 7.1 years (3.6 to 12.0)) with fractures of the shaft of the femur. We reviewed their demographic data, mechanism of injury, associated injuries, the type and location of the fractures, the nail–canal diameter (NCD) ratios and femoral overgrowth at a mean follow-up of 40.7 months (25.2 to 92.7). At that time, the children were divided into two groups, those with femoral overgrowth of < 1 cm (Group 1), and those with overgrowth of ≥ 1 cm (Group 2). The mean femoral overgrowth of all patients was 0.6 cm at final follow-up. Overgrowth of ≥ 1 cm was noted in 11 children (25.6%). The NCD ratio was significantly lower in Group 2 than in Group 1, with an odds ratio of 30.0 (p = 0.003). We believe that a low NCD ratio is an indicator of an unstable configuration with flexible intramedullary nailing, and have identified an association between a low NCD ratio and femoral overgrowth resulting in leg-length discrepancy after flexible intramedullary nailing in paediatric femoral shaft fractures.

1 . A series of 343 tibial shaft fractures proceeding to sound union in adults, and 192 fractures in children, was studied. Groups of fractures differing from each other only in the one particular variable under consideration were compared. 2. The severity of the injury (as assessed by the degree of displacement, of comminution and of compound wounding) was found to be an important determinant of speed of fracture union and of incidence of delayed and non-union. A simple classification of severity of injury is described. 3. Distraction delayed healing. Traction which avoided distraction had no effect on the rate of union of fractures of moderate severity compared with cases of similar severity of injury treated by immobilisation only. Major fractures subjected to traction did take longer to unite on the average, but there was no increase in the incidence of delayed or non-union

A protocol for the treatment of fractures of the middle third of the femur by the early application of a hip spica has been evaluated in 191 children aged 10 years or less. Children without other injuries spent only a few days in hospital for the application and later removal of the spica. At all ages, anterior angulation of less than 20 degrees and valgus angulation of less than 15 degrees were accepted at the one-week review. Acceptance of shortening varied with the age of the child and the stage of treatment, but was 10% or less of the femoral length at the time of spica removal. At late review leg-length discrepancy was rare and clinically insignificant. This method of treatment was simple and effective. It dramatically reduced the cost of care and freed a number of children's hospital beds.

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

Objectives: To assess the stabilizing effect of Ender nails on humeral shaft fracture and to assess proper nail length. Materials and Method: Ender nailing was performed in 67 patients. Age ranged from 22 to 79 years. 9 were open fractures, and the 58 were closed ones; 13 comminuted, 28 spiral, 23 transverse, and 3 segmental fractures. 19 had associated injuries in other parts. One nail was used in 18 cases, two nails in 46 cases, and three nails in 3 cases. In 16 cases long nails were used. In the 12 elderly patients nail was inserted under local anesthesia, In all cases the sling and swathe was applied postoperatively to avoid rotatory shear. Results: Radiologically visible bridging callus was observed at 6.8 weeks on average: the earlist one was at postop 5 weeks, and the latest was at postop 15 weeks. The average clinical union time was 9.3 weeks. In the 6 cases the long nail distracted the fracture gap, and resulted in delayed union. In the 10 remainders the distracted gap was spontaneously reduced when the nails migrated proximally through an entry hole. In cases of proximal nail migration, shoulder pain and partial stiffness were complicated, which disappeared after nail removal. Conclusion: It is found that intramedullary Ender nailing is a simple and less invasive surgical procedure in humerus which brings the successful fracture union with least complications

We describe the use of intramedullary reconstruction nails in the treatment of 14 patients with pathological subtrochanteric fractures and coexisting metastases in the femoral shaft. After nailing, all patients were free from pain and regained mobility. They were followed up clinically and radiologically until death from the primary disease. There were no mechanical failures even when a less than ideal reduction had been achieved.
