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.

Purpose & Background: Posteroanterior mobilisation (PA) is a manual physiotherapy technique that is commonly used as an examination tool and a form of conservative treatment for spinal complaints. The efficacy of this technique is controversial and this may be in part due to a limited knowledge of the mechanical and physiological mechanisms underlying this technique. This study aims to evaluate the ability of interventional MRI to image the mechanics of mobilisation in terms of spinal movement and soft tissue deformation during a PA mobilisation. Methods: 5 normal subjects (4 female, 1 male, mean age 29.6 ± 3.9 years) with no current or history of neck pain requiring intervention were recruited into this study, and written informed consent obtained. Subjects were scanned using a General Electric Signa SP10 Interventional MRI scanner (iMR). This is an open MRI scanner consisting of 2 connected but opposing ring “doughnut” magnets. The gap between these magnets is 56 cm generating a uniform field of 0.5Tesla. Subjects were scanned in the prone position with their necks in either a neutral or flexed position. In each position, subjects underwent a PA mobilisation to the 2nd and 6th cervical vertebrae. Sagittal and axial images of the spine were obtained prior to, during and following the mobilisation. Measurements of intervertebral rotation and translation were obtained from the sagittal images, and measures of soft tissue compression with respect to the spinous process were obtained from the axial images. Paired analysis of variance was used to investigate the impact of the mobilisations in each position. Results: Clear images of vertebral position could be obtained if the mobilisation was sustained once the appropriate force had been delivered. From these images, it is possible to measure vertebral angulation, translation and soft tissue compression. From these measures, it became clear that intersegmental vertebral angulation and translation did not alter as a result of the force applied regardless of cervical position. However, marked and significant changes were seen in terms of soft tissue compression and in some instances overall angulation of the cervical spine. Conclusion: This pilot work suggests that it is feasible to use iMR technology to study the mechanics of spinal mobilisation. Preliminary findings suggest that there is little or no displacement of the vertebral bodies as a result of an AP mobilisation, although there is considerable soft tissue compression

We carried out an audit on the result of achieving early walking in total knee replacement after instituting a new rehabilitation protocol, and assessed its influence on the development of deep-vein thrombosis as determined by Doppler ultrasound scanning on the fifth post-operative day. Early mobilisation was defined as beginning to walk less than 24 hours after knee replacement. Between April 1997 and July 2002, 98 patients underwent a total of 125 total knee replacements. They began walking on the second post-operative day unless there was a medical contraindication. They formed a retrospective control group. A protocol which allowed patients to start walking at less than 24 hours after surgery was instituted in August 2002. Between August 2002 and November 2004, 97 patients underwent a total of 122 total knee replacements. They formed the early mobilisation group, in which data were prospectively gathered. The two groups were of similar age, gender and had similar medical comorbidities. The surgical technique and tourniquet times were similar and the same instrumentation was used in nearly all cases. All the patients received low-molecular-weight heparin thromboprophylaxis and wore compression stockings post-operatively. In the early mobilisation group 90 patients (92.8%) began walking successfully within 24 hours of their operation. The incidence of deep-vein thrombosis fell from 27.6% in the control group to 1.0% in the early mobilisation group (chi-squared test, p < 0.001). There was a difference in the incidence of risk factors for deep-vein thrombosis between the two groups. However, multiple logistic regression analysis showed that the institution of an early mobilisation protocol resulted in a 30-fold reduction in the risk of post-operative deep-vein thrombosis when we adjusted for other risk factors

We performed two independent, randomised, controlled trials in order to assess the potential benefits of immediate weight-bearing mobilisation after rupture of the tendo Achillis. The first trial, on operatively-treated patients showed an improved functional outcome for patients mobilised fully weight-bearing after surgical repair. Two cases of re-rupture in the treatment group suggested that careful patient selection is required as patients need to follow a structured rehabilitation regimen. The second trial, on conservatively-treated patients, provided no evidence of a functional benefit from immediate weight-bearing mobilisation. However, the practical advantages of immediate weight-bearing did not predispose the patients to a higher complication rate. In particular, there was no evidence of tendon lengthening or a higher re-rupture rate. We would advocate immediate weight-bearing mobilisation for the rehabilitation of all patients with rupture of the tendo Achillis

Background. Rapid mobilisation programs, or “fast track” protocols, are aimed at shorter hospital stays. We found a limited local experience with these programs in total hip arthroplasty in South Africa, and decided to introduce a pilot study at our institution. Purpose. This pilot study is aimed at the feasibility and safety of a RM program in the private sector setting, as well as a review of the pertinent literature. Methods. 40 patients who met inclusion criteria underwent THR and TKR according to a specific protocol. Key aspects of the protocol included: minimum use of opiates, high volume pericapsular local block at time of surgery, no urinary catheter, mobilisation within 6 hrs of surgery and no high care admission. Target Discharge was 3 days. Patients were followed up retrospectively and outcomes included; length of stay, intra- and post-operative complications, subjective patient experience, re-admissions and re-operations. Results. 36 patients, (90 %), were discharged by day 3, 4 patients were discharged at day 4. Mean stay 2,8 days, shortest 2 days, and longest 4 days. 3 elderly female patients required catheterization for urinary incontinence, on the first night post surgery. No complications were experienced. The problems that prevented discharge within 3 days were post operative pain and orthostatic hypotension. There were no re-admissions or re-operations. One TKR required manipulation at 6 weeks. 5 patients required changes of dressings at home within one week post surgery. All the patients in this study were extremely satisfied. Conclusion. A rapid mobilisation program is relatively easy to implement although extra paramedical staff input is required. The results of this pilot study show that the protocol was effective and safe, as well as showing a significant hospital cost reduction. The obvious saving of costs are encouraging us to implement the protocol on a wider scale. Appendix.

This study compared the clinical outcomes following mini-open rotator cuff repair (MORCR) between early mobilisation and usual care, involving initial immobilisation. In total, 189 patients with radiologically-confirmed full-thickness rotator cuff tears underwent MORCR and were randomised to either early mobilisation (n = 97) or standard rehabilitation (n = 92) groups. Patients were assessed at six weeks and three, six, 12 and 24 months post-operatively. Six-week range of movement comparisons demonstrated significantly increased abduction (p = 0.002) and scapular plane elevation (p = 0.006) in the early mobilisation group, an effect which was not detectable at three months (p > 0.51) or afterwards. At 24 months post-operatively, patients who performed pain-free, early active mobilisation for activities of daily living showed no difference in clinical outcomes from patients immobilised for six weeks following MORCR. We suggest that the choice of rehabilitation regime following MORCR may be left to the discretion of the patient and the treating surgeon. Cite this article: Bone Joint J 2015;97-B:1257–63

Aims. The authors present the results of a cohort study of 60 adult patients presenting sequentially over a period of 15 years from 1997 to 2012 to our hospital for treatment of thoracic and/or lumbar vertebral burst fractures, but without neurological deficit. . Method. All patients were treated by early mobilisation within the limits of pain, early bracing for patient confidence and all progress in mobilisation was recorded on video. Initial hospital stay was one week. Subsequent reviews were made on an outpatient basis. . Results. The mean duration from admission to final follow-up was three months, and longer follow-up was undertaken telephonically. The mean kyphosis deformity on arrival was 17.4° (5° to 29°); mean kyphosis at final discharge three months later was 19.5° (1° to 28°). Spinal canal encroachment had no influence on successful functional recovery. . Discussion. Pain has not been a significant problem for any patient, irrespective of the degree of kyphosis and no patient has a self-perception of clinical deformity. In all, 11 patients took occasional analgesia. All patients returned to their original work level or better. Two patients died 2.5 years after treatment, from unrelated causes. Take home message: The natural history of thoracolumbar burst fractures without neurology would appear to be benign. Cite this article: Bone Joint J 2016;98-B:97–101

Background: Both chemical and mechanical methods of prophylaxis have reduced the the incidence of thromboembolic complications following Total Knee Replacement (TKR). Only a few studies have shown that mobilisation on the first post operative day further reduces the incidence of thromboembolic phenomena. Aims: We conducted a prospective study to verify not only if early mobilisation but also whether the distance mobilised on the first post-operative day after TKR reduced the incidence of thromboembolic complications. Methodology: The incidence of deep venous thrombosis and pulmonary embolism were compared in 50 consecutive patients who underwent TKR from July 2006 following a change in the mobilisation protocol with 50 consecutive patients who underwent TKR before the protocol was instigated. The mobilisation protocol changed from strict bed rest the first post operative day to mobilisation on the first post operative day. Mobilisation was defined as sitting out of bed or walking for at least 15–30 minutes twice a day. The distance mobilised was accurately recorded by the physiotherapists. All patients underwent duplex scans of both lower limbs on the fourth post operative day. Results: There was a Significant reduction in the incidence of thromboembolic complications in the mobilisation group (7 in total) compared to the control group (16 in total) (p=0.03). Furthermore in the mobilisation group the odds of developing a thromboemobloic complication was Significantly reduced the greater the distance the patient mobilised, (Chi squared linear trend=8.009, p =0.0047). Early mobilisation in the first 24 hours post TKR is a cheap and effective way to reduce the incidence of post-operative DVT

Patients undergoing total knee arthroplasty (TKA) experience significant post-operative pain. We report the results of a new comprehensive patient care plan to manage peri-operative pain, enable early mobilisation and reduce length of hospital stay in TKA. A prospective audit of 1081 patients undergoing primary TKA during 2008 and 2009 was completed. All patients followed a planned programme including pre-operative patient education, pre-emptive analgesia, spinal/epidural anaesthesia with propofol sedation, intra-articular soft tissue wound infiltration, post-operative high volume intermittent ropivacaine boluses with an intra-articular catheter and early mobilisation. The primary outcome measure was the day of discharge from hospital. Secondary outcomes were verbal rating pain scores on movement, time to first mobilisation, nausea and vomiting scores, urinary catheterisation for retention, need for rescue analgesia, maximum flexion at discharge and six weeks post-operatively, and Oxford score improvement. The median day of discharge to home was post-operative day four. Median pain score on mobilisation was three for first post-operative night, day one and two. 35% of patients ambulated on the day of surgery and 95% of patients within 24 hours. 79% patients experienced no nausea or vomiting. Catheterisation rate was 6.9%. Rescue analgesia was required in 5% of cases. Median maximum flexion was 85° on discharge and 93° at six weeks post-operatively. Only 6.6% of patients had a reduction in maximum flexion (loss of more than 5°) at six weeks. Median Oxford score had improved from 42 pre-operatively to 27 at six weeks post-operatively. The infection rate was 0.7% and the DVT and PE rates were 0.6% and 0.5% respectively. This multidisciplinary approach provides satisfactory post-operative analgesia allowing early safe ambulation and discharge from hospital. Anticipated problems did not arise, with early discharge not being detrimental to flexion achieved at six weeks and infection rates not increasing with the use of intra-articular catheters

Despite surgeons' concerns early discharge was not detrimental to flexion achieved at six weeks and infection rates did not increase with the use of intra-articular catheters

We randomly selected 39 patients undergoing excision of the trapezium for osteoarthritis of the first carpometacarpal joint into two groups, with mobilisation either at one or at four weeks after operation. The patients were reviewed at a median of six months (6 to 8). The clinical details, the severity of the disease and the preoperative clinical measurements of both groups were similar. Excision of the trapezium resulted in significant improvement in objective and subjective function. Comparison of the outcomes of the two groups showed no differences except that patients found early mobilisation significantly more convenient. Although there was no significant difference in the range of movement between the groups, there was a small loss of movement at the metacarpophalangeal joint in the late mobilisation group. Our findings show that simple excision of the trapezium is an effective procedure for patients with carpometacarpal osteoarthritis of the thumb and that prolonged splintage is neither necessary nor desirable

The results of a prospective controlled trial of early mobilisation of Colles' fractures in the elderly are presented. Early mobilisation produced less pain and a stronger grip. It did not lead to any greater loss of reduction of the fracture. However, there was no significant improvement in the final range of movement of the wrist. Immobilisation of the wrist for six weeks in plaster is extremely inconvenient for the elderly living alone and the patients greatly appreciated the reduction of this period of time to a minimum

Aims: To compare two protocols of early mobilisation for minimally displaced radial head fractures through a single-blinded, prospective randomised trial. Methods: Sixty patients were randomly allocated to either immediate active mobilisation or 5-day delay before active mobilisation was commenced. Patients were reviewed at 7 days, 4 weeks and 3 months after injuries. A blinded observer assessed each patient. Results: All fractures united by the third month. At the end of 7days, the mobilisation group had less pain (VAS 6 vs 7.6, p=0.002); greater ßexion (mean 112û vs 98û, p=0.0004); greater strength in supination (p< 0.001) and better elbow function (Morrey Score 54 vs 43, p=0.005). By the fourth week, both groups were comparable in all parameters and improvement continued into the third month. Mean limit of extension at the third month were 2.3û in the immediate mobilisation group and 1.8û in the delayed group (NS). All had excellent function on the basis of the Morrey Score. Conclusions: Immediate mobilisation did not adversely affect the outcome; the patients had less pain and better elbow function at one week post-injury. Pain, ranges of movement and function were similar by the fourth week post-injury

Introduction. Venous thromboembolism (VTE) is a significant cause of patient morbidity and mortality, the risk of which increases in orthopaedic patients with lower limb immobilisation. This incidence should in theory reduce if the patients are ambulatory early in the treatment phase. The aim of this study was, therefore, to identify a difference in the incidence of symptomatic VTE by treating acute Achilles tendon rupture patients with conventional non-weight bearing plaster versus functional weight bearing mobilisation. Methodology. The notes of 91 consecutive patients with acute Achilles tendon rupture were retrospectively reviewed and prospectively followed. The patients' demographics, treatment modality (non-weight bearing plaster versus weight bearing boot), and the type of plaster immobilisation was compared to assess whether they affect the incidence of clinical VTE. The predisposing risk factors were also analysed between the treatment groups. Out of 91 patients, 50 patients with acute Achilles tendon rupture were treated conservatively in a conventional non-weight bearing immobilisation cast. From these 50 patients, 3 then underwent surgery and were therefore excluded from the results. On the other hand, 41 patients were treated with functional weight bearing mobilisation (Vacupad). Patients who did have a symptomatic thromboembolic event also had an ultrasound scan to confirm a deep vein thrombosis of the lower limb or a CT-scan to confirm pulmonary embolism. Results. Out of the 47 patients who were treated conservatively in a non-weight bearing plaster cast, 9 patients had a thromboembolic event (19.1%). On the other hand, out of the 41 patients who were treated with functional weight bearing mobilisation, only 2 patients had a symptomatic thromboembolic event (4.2%). This was statistically significant (p=0.012). This shows that patients who are treated in a non-weight bearing plaster have about five times increased risk of developing a sypmptomatic VTE compared to those treated by functional weight bearing mobilisation. There was however no difference in the predisposing factors in patients who developed VTE compared to those who did not. Conclusion. The incidence of symptomatic VTE after acute Achilles tendon rupture is high and under-recognised. Asymptomatic VTE after this injury is probably even higher. There is a significant decrease in the clinical incidence of thromboembolic events in patients treated conservatively with early mobilisation in the functional weight bearing boot compared to those treated in a non-weight bearing cast. There is a need for further research to define the possible benefit of thromboprophylaxis in patients treated by non-weight bearing plasters

Introduction. Peri prosthetic fracture is a recognised complication following Total ankle arthroplasty (TAA). There is limited literature on post operative management following TAA and controversies exist based on surgeon preferences. This project reports the incidence of peri- prosthetic fractures in patients managed with 2 different post-operative protocols. Materials and Methods. Patients undergoing primary TAA with a diagnosis of Osteoarthritis (OA) or Post-traumatic Osteoarthritis (PTOA) were recruited into a randomized controlled trial. These patients did not require any additional procedures. Patients were consented for the trial and randomized to one of two treatment groups (Early mobilisation after surgery vs. immobilisation in a plaster cast for 6 weeks post operatively). Plaster group patients underwent a graduated physiotherapy program from 6-12 weeks and early mobilisation group patients from 1-12 weeks. Complications any were recorded at 2, 4, 6 and 12 weeks post-operatively. Results. A total of 16 ankle replacements were done for a diagnosis of OA (10) and PTOA (6). Mean age was 58 years (±11.75) for the plaster group and 64 years (± 9.32) for the early mobilisation group. 7 patients were randomized to the plaster group and 9 patients were randomized to the early mobilisation group. Of the plaster group 1 patient sustained an intra-operative fracture tibia and 2 patients reported with a fractured medial malleolus. Of the early mobilisation group, 1 patient reported with a peri prosthetic fracture tibia at 6 weeks and 3 patients reported a fractured medial malleolus at 3 months follow up. The percentage of fracture incidence between plaster versus early immobilisation group was 42.8% and 44.4 % respectively. Conclusions. These early results demonstrate no significant differences in the incidence of fracture rates between groups. Further studies of post-operative management are needed to study the correlation with peri-prosthetic fracture rates after TAA

Aims: Circulating endothelial precursor cells (CEPs) are thought to play a role in angiogenesis. We investigated the angiogenic stress of musculoskeletal trauma on CEP kinetics in trauma patients and their bone marrow progenitor populations in a murine model. Methods: Peripheral blood mononuclear cells (PB-MNCs) were isolated from patients (n=12) on consecutive days following closed lower-limb diaphyseal fractures. CEP levels, deþned by the surface expression patterns of VEGFR2, CD34 and AC133 were determined and cytokine analysis of collected serum was performed. Bonemarrow precursors deþned byLy-6A/E and c-Kit expression were harvested following the traumatic insult from the murine model and quantiþed on ßow cytometry. Human and murine progenitor populations were cultured on þbronectin and examined for markers of endothelial cell lineage (Ulexeuropaeus- agglutinin-1 binding and acetylated-LDL uptake) and cell morphology. Statistical analysis was performed using variance analysis. Results: A consistent increase in human CEPs levels was noted within 72 hours of the initial insult, the percentage increase over day 1 reaching 300% (p=0.008) and returning to normal levels by day 10. Murine bone marrow precursors were mobilisd within 24 hrs peaking at 48hrs (900% p=0.035). On culture, morphologically characteristic endotheliallike cells binding UEA-1 and incorporating LDL were identiþed. Serum VEGF levels increased signiþcantly within 24 hrs of the insult, (p=0.018) preceeding the peak in CEP mobilisation. Conclusion: We propose that musculoskeletal trauma through the release of chemokines such as VEGF, promotes rapid mobilisation of CEPs from born marrow, which have the potential to contribute to reparative neovascularisation. Strategies to enhance CEPs kinetics may accelerate this process and offer a therapeutic role in aberrant fracture healing

Conclusion. There is a significant decrease in the clinical incidence of thromboembolic events in patients treated conservatively with early mobilisation in the functional weight bearing boot compared to those treated in a non- weight bearing cast

The aim of this study was to compare immediate weight-bearing mobilisation with traditional plaster casting in the rehabilitation of non-operatively treated Achilles tendon ruptures. Forty-eight patients with Achilles tendon rupture were randomised into two groups. The treatment group was fitted with an off-the-shelf carbon-fibre orthotic and the patients were mobilised with immediate full weight-bearing. The control group was immobilised in traditional serial equinus plaster casts. The heel raise within the orthotic and the equinus position of the cast was reduced over a period of eight weeks and then the orthotic or cast was removed. Each patient followed the same rehabilitation protocol. The primary outcome measure was return to the patient's normal activity level as defined by the patient. There was no statistical difference between the groups in terms of return to normal work [p=0.37] and sporting activity [p=0.63]. Nor was there any difference in terms of return to normal walking and stair climbing. There was weak evidence for improved early function in the treatment group. There was 1 re-rupture of the tendon in each group and a further failure of healing in the control group. One patient in the control group died from a fatal pulmonary embolism secondary to a DVT in the ipsilateral leg. Immediate weight-bearing mobilisation provides practical and functional advantages to patients treated non-operatively after Achilles tendon rupture. However, this study provides only weak evidence of faster rehabilitation
