Patient-reported outcomes in young patients with isolated fracture of the hip.

AIMS: Hip fractures in patients < 60 years old currently account for only 3% to 4% of all hip fractures in England, but this proportion is increasing. Little is known about the longer-term patient-reported outcomes in this potentially more active population. The primary aim is to examine patient-reported outcomes following isolated hip fracture in patients aged < 60 years. The secondary aim is to determine an association between outcomes and different types of fracture pattern and/or treatment implants. METHODS: All hip fracture patients aged 18 to 60 years admitted to a single centre over a 15-year period were used to identify the study group. Fracture pattern (undisplaced intracapsular, displaced intracapsular, and extracapsular) and type of operation (multiple cannulated hip screws, angular stable fixation, hemiarthroplasty, and total hip replacement) were recorded. The primary outcome measures were the Oxford Hip Score (OHS), the EuroQol five-dimension questionnaire (EQ-5D-3L), and EQ-visual analogue scale (VAS) scores. Preinjury scores were recorded by patient recall and postinjury scores were collected at a mean of 57 months (9 to 118) postinjury. Ethics approval was obtained prior to study commencement. RESULTS: A total of 72 patients were included. There was a significant difference in pre- and post-injury OHS (mean 9.8 point reduction (38 to -20; p < 0.001)), EQ-5D (mean 0.208 reduction in index (0.897 to -0.630; p < 0.001)), and VAS , and VAS (mean 11.6 point reduction (70 to -55; p < 0.001)) Fracture pattern had a significant influence on OHS (p < 0.001) with extracapsular fractures showing the least favourable long-term outcome. Fixation type also impacted significantly on OHS (p = 0.011) with the worst outcomes in patients treated by hemiarthroplasty or angular stable fixation. CONCLUSION: There is a significant reduction in function and quality of life following injury, with all three patient-reported outcome measures used, indicating that this is a substantial injury in younger patients. Treatment with hemiarthroplasty or angular stable devices in this cohort were associated with a less favourable hip score outcome. Cite this article: Bone Joint J 2020;102-B(6):766-771.

Tibial nailing using a suprapatellar rather than an infrapatellar approach significantly reduces anterior knee pain postoperatively: a multicentre clinical trial.

AIMS: The aim of this study was to compare the incidence of anterior knee pain after antegrade tibial nailing using suprapatellar and infrapatellar surgical approaches. PATIENTS AND METHODS: A total of 95 patients with a tibial fracture requiring an intramedullary nail were randomized to treatment using a supra- or infrapatellar approach. Anterior knee pain was assessed at four and six months, and one year postoperatively, using the Aberdeen Weightbearing Test - Knee (AWT-K) score and a visual analogue scale (VAS) score for pain. The AWT-K is an objective patient-reported outcome measure that uses weight transmitted through the knee when kneeling as a surrogate for anterior knee pain. RESULTS: A total of 53 patients were randomized to a suprapatellar approach and 42 to an infrapatellar approach. AWT-K results showed a greater mean proportion of weight transmitted through the injured leg compared with the uninjured leg when kneeling in the suprapatellar group compared with the infrapatellar group at all timepoints at all follow-up visits. This reached significance at four months for all timepoints except 30 seconds. It also reached significance at six months at 0 seconds, and for one year at 60 seconds. CONCLUSION: The suprapatellar surgical approach for antegrade tibial nailing is associated with less anterior knee pain postoperatively compared with the infrapatellar approach Cite this article: Bone Joint J 2019;101-B:1138-1143.

Predictors of direct home discharge following fractured neck of femur.

INTRODUCTION Direct home discharge (DHD) following hip fracture surgery represents a challenging proposition. The aim of this study was to identify factors influencing the discharge destination (home vs alternative location) for patients admitted from their own home with a fractured neck of femur. METHODS A retrospective cohort study of prospectively collected major trauma centre data was performed, identifying 10,044 consecutive hip fracture admissions between 2000 and 2012. RESULTS Two-thirds of the patients (n=6,742, 67%) were admitted from their own home. Half of these (n=3,509, 52%) returned directly to their own home while two-fifths (n=2,640, 39%) were discharged to an alternative location; 593 (9%) died. The following were identified as independent variables associated with a higher likelihood of DHD: younger patients, female sex, an abbreviated mental test score of 10, absence of certain co-morbidities, cohabiting, walking independently outdoors, no use of walking aids, no assistance required with basic activities of daily living and intracapsular fracture. CONCLUSIONS Identifying those at risk of being discharged to an alternative location following admission from home on the basis of identified preoperative indices could assist in streamlining the postoperative care phase. Pre-emptive action may help increase the numbers of patients discharged directly home and reduce the number requiring additional rehabilitation prior to discharge home with its associated socioeconomic effect.

A cross-sectional study of the impact of physiotherapy and self directed exercise on the functional outcome of internally fixed isolated unimalleolar Weber B ankle fractures.

This study aimed to measure the functional outcome and quality of life in a group of patients with the same fracture type (unimalleolar Weber B ankle fractures) treated operatively at various time points and to explore the determinants of such outcomes. A cross-sectional retrospective population study was conducted. Validated Patient Related Outcome Measures (PROMs) and patient interviews were used. Fifty-one patients were included with a mean age of 54.9 years. Mean follow-up was 25 months (range 4-46 months). Mean functional scores were high (mean AOFAS 79.2, O&M 75.7, VAS-FA 80.5). However, 32% of patients did not classify themselves as fully recovered during interviews. Patient reported self-directed exercise had a statistically significant positive effect on self-reported patient perceptions of outcome (p=0.022) and PROMs (AOFAS p=0.01, O&M p=0.016, VAS-FA p=0.011). Formal physiotherapy rehabilitation was found to have no effect on self-reported patient perceptions (p=0.242) or PROMs (AOFAS p=0.8, O&M p=0.73, VAS-FA p=0.46). Our finding that physical activity is associated with improved outcome would suggest structured exercise programmes should be considered in place of physiotherapy to optimise patient outcomes.

The effect of surgical experience on the amount of radiation exposure from fluoroscopy during dynamic hip screw fixation.

INTRODUCTION Dynamic hip screw (DHS) fixation for proximal femur fractures is one of the most common procedures in trauma that requires the use of fluoroscopy. Emphasis is often placed on producing the 'perfect picture', which may lead to excessive use of fluoroscopy, without added patient benefit. This study, the largest of its kind, aimed to determine the effect of surgical experience on the amount of radiation exposure from fluoroscopy during DHS fixation. METHODS All hospital admissions for extracapsular proximal femur fractures to our institution between 2007 and 2012 were analysed. Patient demographics, fracture configuration, grade of surgeon and the total radiation dose after fixation were recorded. Analysis of variance was performed to assess differences in radiation levels between different grades of surgeon. RESULTS A total of 1,203 patients with a mean age of 81.3 years (range: 21-105 years) were included in the study. The majority of the fractures were three-part (33.3%), followed by two-part (32.2%), four-part (25.7%) and basicervical (8.9%). Registrars (ST3-ST8) used a significantly higher radiation dose than consultants for all fracture types (p=0.009). When analysed separately by trainee group, the most junior registrars (ST3-ST4) and the most senior registrars (ST7-ST8) were found to use significantly higher radiation levels than consultants (p=0.037 and p<0.001 respectively). CONCLUSIONS The level of surgical experience does influence the amount of radiation exposure from fluoroscopy during DHS fixation. Surgical trainees should not ignore the potential harmful effects of radiation and should be equipped with the knowledge of how to keep the radiation exposure as low as possible.

The epidemiology and functional outcomes of operative fixation of extracapsular proximal femoral fractures (AO 31-A) in young adults.

Proximal femoral fractures in adults under 50 years are not as common as in the elderly, but may have just as significant an impact. There is little in the literature describing the functional outcomes of fixation in this age group. Our aim was to assess the clinical and functional outcomes of operative management of extracapsular proximal femoral fractures (AO 31-A) in the young adult (<50 years). Consecutive skeletally mature patients <50 years undergoing operative fixation of these fractures were obtained from a prospective database over a 12-year period. Complications and mortality data were obtained from this database and case note review. Outcome scores were obtained via postal questionnaires. Eighty-eight patients were included in the study of which 74 (84%) had fixation with the dynamic hip screw. The mean age was 39 years (range 17-50) with a male preponderance (73.8%). Mean hospital stay was 14 days (range 2-94). Seventeen (19.3%) patients had died at a mean of 40 months from their operation date. The 1-year mortality was 4.5%. There were five complications (5.7%). SF-36 and EuroQol 5D scores showed that 5-10% had severe problems with a 20% decrease in quality of life compared to population norms. The biggest differences were in the physical function modalities. One-third had fair to poor hip function as assessed by the Oxford Hip Score. Though these injuries are relatively rare in this age group, they do have significant mortality and functional impairment reflecting a higher energy of injury rather than the frailty seen in the elderly.

Management of rib fractures in traumatic flail chest: a meta-analysis of randomised controlled trials.

AIMS: Flail chest from a blunt injury to the thorax is associated with significant morbidity and mortality. Its management globally is predominantly non-operative; however, there are an increasing number of centres which undertake surgical stabilisation. The aim of this meta-analysis was to compare the efficacy of this approach with that of non-operative management. PATIENTS AND METHODS: A systematic search of the literature was carried out to identify randomised controlled trials (RCTs) which compared the clinical outcome of patients with a traumatic flail chest treated by surgical stabilisation of any kind with that of non-operative management. RESULTS: Of 1273 papers identified, three RCTs reported the results of 123 patients with a flail chest. Surgical stabilisation was associated with a two thirds reduction in the incidence of pneumonia when compared with non-operative management (risk ratio 0.36, 95% confidence interval (CI) 0.15 to 0.85, p = 0.02). The duration of mechanical ventilation (mean difference -6.30 days, 95% CI -12.16 to -0.43, p = 0.04) and length of stay in an intensive care unit (mean difference -6.46 days, 95% CI 9.73 to -3.19, p = 0.0001) were significantly shorter in the operative group, as was the overall length of stay in hospital (mean difference -11.39, 95% CI -12.39 to -10.38, p < 0.0001). CONCLUSION: Surgical stabilisation for a traumatic flail chest is associated with significant clinical benefits in this meta-analysis of three relatively small RCTs.

A unified theory of bone healing and nonunion: BHN theory.

This article presents a unified clinical theory that links established facts about the physiology of bone and homeostasis, with those involved in the healing of fractures and the development of nonunion. The key to this theory is the concept that the tissue that forms in and around a fracture should be considered a specific functional entity. This 'bone-healing unit' produces a physiological response to its biological and mechanical environment, which leads to the normal healing of bone. This tissue responds to mechanical forces and functions according to Wolff's law, Perren's strain theory and Frost's concept of the "mechanostat". In response to the local mechanical environment, the bone-healing unit normally changes with time, producing different tissues that can tolerate various levels of strain. The normal result is the formation of bone that bridges the fracture - healing by callus. Nonunion occurs when the bone-healing unit fails either due to mechanical or biological problems or a combination of both. In clinical practice, the majority of nonunions are due to mechanical problems with instability, resulting in too much strain at the fracture site. In most nonunions, there is an intact bone-healing unit. We suggest that this maintains its biological potential to heal, but fails to function due to the mechanical conditions. The theory predicts the healing pattern of multifragmentary fractures and the observed morphological characteristics of different nonunions. It suggests that the majority of nonunions will heal if the correct mechanical environment is produced by surgery, without the need for biological adjuncts such as autologous bone graft.

Early management of the severely injured major trauma patient.

The major trauma team relies on an efficient, communicative team to ensure patients receive the best quality care. This requires a comprehensive handover, rapid systematic review, and early management of life- and limb-threatening injuries. These multiple injured patients often present with complex conditions in a dynamic situation. The importance of team work, communication, senior decision-making, and documentation cannot be underestimated.

The early management of patients with multiple injuries: an evidence-based, practical guide for the orthopaedic surgeon.

There have been many advances in the resuscitation and early management of patients with severe injuries during the last decade. These have come about as a result of the reorganisation of civilian trauma services in countries such as Germany, Australia and the United States, where the development of trauma systems has allowed a concentration of expertise and research. The continuing conflicts in the Middle East have also generated a significant increase in expertise in the management of severe injuries, and soldiers now survive injuries that would have been fatal in previous wars. This military experience is being translated into civilian practice. The aim of this paper is to give orthopaedic surgeons a practical, evidence-based guide to the current management of patients with severe, multiple injuries. It must be emphasised that this depends upon the expertise, experience and facilities available within the local health-care system, and that the proposed guidelines will inevitably have to be adapted to suit the local resources.

Ward-based rather than team-based junior surgical doctors reduce mortality for patients with a fracture of the proximal femur: results from a two-year observational study.

We performed a retrospective study of a departmental database to assess the efficacy of a new model of orthopaedic care on the outcome of patients with a fracture of the proximal femur. All 1578 patients admitted to a university teaching hospital with a fracture of the proximal femur between December 2007 and December 2009 were included. The allocation of Foundation doctors years 1 and 2 was restructured from individual teams covering several wards to pairs covering individual wards. No alterations were made in the numbers of doctors, their hours, out-of-hours cover, or any other aspect of standard patient care. Outcome measures comprised 30-day mortality and cause, complications and length of stay. Mortality was reduced from 11.7% to 7.6% (p = 0.007, Cox's regression analysis); adjusted odds ratio was 1.559 (95% confidence interval 1.128 to 2.156). Reductions were seen in Clostridium difficile colitis (p = 0.017), deep wound infection (p = 0.043) and gastrointestinal haemorrhage (p = 0.033). There were no differences in any patient risk factors (except the prevalence of chronic obstructive pulmonary disease), cause of death and length of stay before and after intervention. The underlying mechanisms are unclear, but may include improved efficiency and medical contact time. These findings may have implications for all specialties caring for patients on several wards, and we believe they justify a prospective trial to further assess this effect.

The clinical outcome of scaphoid fracture malunion at 1 year.

The aim of this study was to assess the effect of malunion of scaphoid fractures on the clinical outcome at 1 year. Forty-two consecutive patients with united scaphoid waist fractures which had been treated non-operatively underwent longitudinal CT scans to confirm union and assess malunion at 12 to 18 weeks after injury. A blind clinical assessment was made and the Patient Evaluation Measure (PEM) and DASH questionnaires were completed by all the patients 1 year after injury. The group consisted of 38 men and four women with a mean age of 31 years at the time of injury. Correlation analysis revealed no significant relationships between any of the outcome measures (range of motion, grip strength and PEM and DASH scores) and any of the three measures of malunion (height-to-length ratio, the dorsal cortical angle and the lateral intra-scaphoid angle).

Do young patients with malunited fractures of the distal radius inevitably develop symptomatic post-traumatic osteoarthritis?

Fractures of the distal radius occurring in young adults are treated increasingly by open surgical techniques, partly because of concern that failure to restore the alignment of the fracture accurately may cause symptomatic post-traumatic osteoarthritis in future years. We reviewed 106 adults who had sustained a fracture of the distal radius between 1960 and 1968 and who were below the age of 40 years at the time of injury. We carried out a clinical and radiological assessment at a mean follow-up of 38 years (33 to 42). No patient had required a salvage procedure. While there was radiological evidence of post-traumatic osteoarthritis after an intra-articular fracture in 68% of patients (27 of 40), the disabilities of the arm, shoulder and hand (DASH) scores were not different from population norms, and function, as assessed by the Patient Evaluation Measure, was impaired by less than 10%. Ordinal logistic regression analysis showed a significant relationship between narrowing of the joint space and extra-articular malunion (dorsal angulation and radial shortening) as well as intra-articular injury. Multivariate analysis revealed that grip strength had fallen to 89% of that of the uninjured side in the presence of dorsal malunion, but no measure of extra-articular malunion was significantly related to either the Patient Evaluation Measure or DASH scores. While anatomical reduction is the principal aim of treatment, imperfect reduction of these fractures may not result in symptomatic arthritis in the long term, and this should be considered when counselling patients on the risks and benefits of the many treatment options available.

The internal consistency and validity of the Patient Evaluation Measure for outcomes assessment in distal radius fractures.

The internal consistency and validity of the Patient Evaluation Measure (PEM) was investigated in the setting of the distal radius fracture by assessing 200 patients 6 to 42 years after injury using the PEM and DASH questionnaires and objective measures of outcome. The PEM was completed separately for both the injured and uninjured wrist. We found highly significant correlations between the PEM and objective measures and, also, between the PEM and DASH scores. We also calculated a comparative PEM score by subtracting the score of the uninjured wrist from that of the injured side, to eliminate the effect of co-existing disease. This score was more strongly correlated with outcome than the PEM alone. We suggest that the PEM is a valid method of assessing distal radial fracture outcome. It may, also, be used to reduce the effect of symptoms from coexisting bilaterally represented pathologies.

Preservation of the ulnar bursa within the carpal tunnel: does it improve the outcome of carpal tunnel surgery? A randomized, controlled trial.

BACKGROUND: It was hypothesized that preserving a layer of gliding tissue, the parietal layer of the ulnar bursa, between the contents of the carpal tunnel and the soft tissues incised during carpal tunnel surgery might reduce scar pain and improve grip strength and function following open carpal tunnel decompression. METHODS: Patients consented to randomization to treatment with either preservation of the parietal layer of the ulnar bursa beneath the flexor retinaculum at the time of open carpal tunnel decompression (fifty-seven patients) or division of this gliding layer as part of a standard open carpal tunnel decompression (sixty-one patients). Grip strength was measured, scar pain was rated, and the validated Patient Evaluation Measure questionnaire was used to assess symptoms and disability preoperatively and at eight to nine weeks following the surgery in seventy-seven women and thirty-four men; the remaining seven patients were lost to follow-up. RESULTS: There was no difference between the groups with respect to age, sex, hand dominance, or side of surgery. Grip strength, scar pain, and the Patient Evaluation Measure score were not significantly different between the two groups, although there was a trend toward a poorer subjective outcome as demonstrated by the questionnaire in the group in which the ulnar bursa within the carpal tunnel had been preserved. Preserving the ulnar bursa within the carpal tunnel did, however, result in a lower prevalence of suspected wound infection or inflammation (p = 0.04). CONCLUSIONS: In this group of patients, preservation of the ulnar bursa around the median nerve during open carpal tunnel release produced no significant difference in grip strength or self-rated symptoms. We recommend incision of the ulnar bursa during open carpal tunnel decompression to allow complete visualization of the median nerve and carpal tunnel contents.

Clinical and endocrine data for goserelin plus anastrozole as second-line endocrine therapy for premenopausal advanced breast cancer.

A total of 16 premenopausal women with metastatic breast cancer (N=13) or locally advanced primary breast cancer (N=3) were treated with a combination of a gonadotropin-releasing hormone agonist goserelin, and a selective aromatase inhibitor anastrozole. All had previously been treated with goserelin and tamoxifen. In all, 12 patients (75%) achieved objective response or durable stable disease at 6 months, with a median duration of remission of 17+ months (range 6-47 months). Four patients still have clinical benefit. Introduction of goserelin and tamoxifen resulted in an 89% reduction in mean oestradiol levels (pretreatment vs 6 months=224 vs 24 pmol l(-1)) (P<0.0001). Substitution of tamoxifen by anastrozole on progression resulted in a further 76% fall (to 6 pmol l(-1) at 3 months) (P<0.0001). Treatment with goserelin and tamoxifen led to a 90% fall in the mean follicle-stimulating hormone (P<0.001). This was reversed once therapy was changed to goserelin and anastrozole. A similar initial reduction was seen in the mean luteinising hormone levels, but substitution of tamoxifen by anastrozole on progression resulted in no significant change. Goserelin and tamoxifen did not lead to any significant change in testosterone and androstenedione levels. The combined use of goserelin and anastrozole as second-line endocrine therapy produces a significant clinical response of worthwhile duration, with demonstrable endocrine changes, in premenopausal women with advanced breast cancer, and offers them another therapeutic option. Further studies involving more patients and longer follow-up are indicated.

Arthroscopic washout of the shoulder for septic arthritis in infants. A new technique.

The operative treatment of septic arthritis of the shoulder in infants has been facilitated by the use of a 30 degrees wrist arthroscope. We have treated three children under the age of three years using this technique. After initial aspiration of the joint, an arthroscope was inserted using the posterior approach. Washout was performed under direct vision and complete clearance of pus allowed assessment of the inflammation and the damage to articular cartilage. The procedure was minimally invasive and gave excellent cosmesis without compromising care. Full recovery was achieved with a single intervention.
