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.

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

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

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

Unilateral Colles' fractures in 187 patients over the age of 55 years were studied in a randomised prospective trial: 97 fractures were minimally displaced and were treated either conventionally or in a crepe bandage; 90 displaced Colles' fractures were reduced and of these 47 were treated conventionally while 43 were encouraged to mobilise the wrist in a cast which restricted extension. Early wrist movement hastened functional recovery and led to earlier resolution of wrist swelling. Discomfort was no greater than in patients who were treated conventionally. The bony deformity, which recurred irrespective of the method of treatment, was not adversely affected by early mobilisation

Forty patients with acute complete rupture of the calcaneal tendon were managed conservatively and randomly allocated to treatment groups using either cast immobilisation for eight weeks, or cast immobilisation for three weeks, followed by controlled early mobilisation in a Sheffield splint. The splint is an ankle-foot orthosis which holds the ankle in 15 degrees of plantar flexion, but allows some movement at the metatarsophalangeal joints. It is removed to allow controlled movement during physiotherapy. Patients treated with the splint regained mobility significantly more quickly (p less than 0.001) and preferred the splint to the plaster cast. The range of dorsiflexion at the ankle improved more rapidly after treatment in the splint (p less than 0.001), and patients were able to return to normal activities sooner. Recovery of the power of plantar flexion was similar in the two treatment groups, and no patient had excessive lengthening of the tendon. One re-rupture occurred in each group

We assessed the frequency and causes of neurological deterioration in 59 patients with spinal cord injury on whom reports were prepared for clinical negligence litigation. In those who deteriorated neurologically we assessed the causes of the change in neurology and whether that neurological deterioration was potentially preventable. In all 27 patients (46%) changed neurologically, 20 patients (74% of those who deteriorated) had no primary neurological deficit. Of those who deteriorated, 13 (48%) became Frankel A. Neurological deterioration occurred in 23 of 38 patients (61%) with unstable fractures and/or dislocations; all 23 patients probably deteriorated either because of failures to immobilise the spine or because of inappropriate removal of spinal immobilisation. Of the 27 patients who altered neurologically, neurological deterioration was, probably, avoidable in 25 (excess movement in 23 patients with unstable injuries, failure to evacuate an epidural haematoma in one patient and over-distraction following manipulation of the cervical spine in one patient). If existing guidelines and standards for the management of actual or potential spinal cord injury had been followed, neurological deterioration would have been prevented in 25 of the 27 patients (93%) who experienced a deterioration in their neurological status.

We present the results of a prospective trial of osteotomy of the metatarsal neck for hallux valgus in 31 feet of 23 women, using a new stapling device with no plaster splintage and early weight-bearing. Surgery was performed for pain (29 feet) and difficulty with footwear (nine feet). The average time for return to light work was 3.3 weeks, and to full work 8.3 weeks after operation. Seventeen patients had full recovery within three months and 21 of the 23 patients had complete relief of pain. Shoes were more comfortable in 17 feet and 9 patients could wear narrower shoes. Only two patients were unsatisfied with the appearance of the foot. All the osteotomies united, and the average hallux valgus angle was improved on radiographs from 35 degrees to 23 degrees. The mean first metatarsal angle was reduced from 16 degrees to 11 degrees. The new technique allows more accurate surgery and easier postoperative management.

1. The term "bumper fracture" is colourful but usually inaccurate. The injury is a valgus split or crush.

2. A series of sixty bumper fractures is reported: forty-eight were treated without operation or plaster.

3. Twenty-seven of the forty-eight patients treated without splintage have been followed up for more than five years, and seventeen of these for more than ten years.

4. The results are satisfactory and there is no evidence that there is any late deterioration of the joint.

5. It is suggested that bumper fractures should be treated without operation and without fixation in plaster.

Most patients with a nightstick fracture of the ulna are treated conservatively. Various techniques of immobilisation or early mobilisation have been studied. We performed a systematic review of all published randomised controlled trials and observational studies that have assessed the outcome of these fractures following above- or below-elbow immobilisation, bracing and early mobilisation. We searched multiple electronic databases, related bibliographies and other studies. We included 27 studies comprising 1629 fractures in the final analysis. The data relating to the time to radiological union and the rates of delayed union and nonunion could be pooled and analysed statistically. We found that early mobilisation produced the shortest radiological time to union (mean 8.0 weeks) and the lowest mean rate of nonunion (0.6%). Fractures treated with above- or below-elbow immobilisation and braces had longer mean radiological times to union (9.2 weeks, 9.2 weeks and 8.7 weeks, respectively) and higher mean rates of nonunion (3.8%, 2.1% and 0.8%, respectively). There was no statistically significant difference in the rate of non- or delayed union between those treated by early mobilisation and the three forms of immobilisation (p = 0.142 to p = 1.000, respectively). All the studies had significant biases, but until a robust randomised controlled trial is undertaken the best advice for the treatment of undisplaced or partially displaced nightstick fractures appears to be early mobilisation, with a removable forearm support for comfort as required.

The nervous system is known to be involved in inflammation and repair. We aimed to determine the effect of physical activity on the healing of a muscle injury and to examine the pattern of innervation. Using a drop-ball technique, a contusion was produced in the gastrocnemius in 20 rats. In ten the limb was immobilised in a plaster cast and the remaining ten had mobilisation on a running wheel. The muscle and the corresponding dorsal-root ganglia were studied by histological and immunohistochemical methods. In the mobilisation group, there was a significant reduction in lymphocytes (p = 0.016), macrophages (p = 0.008) and myotubules (p = 0.008) between three and 21 days. The formation of myotubules and the density of nerve fibres was significantly higher (both p = 0.016) compared with those in the immobilisation group at three days, while the density of CGRP-positive fibres was significantly lower (p = 0.016) after 21 days. Mobilisation after contusional injury to the muscle resulted in early and increased formation of myotubules, early nerve regeneration and progressive reduction in inflammation, suggesting that it promoted a better healing response

We investigated the detailed anatomy of the gluteus maximus, gluteus medius and gluteus minimus and their neurovascular supply in 22 hips in 11 embalmed adult Caucasian human cadavers. This led to the development of a surgical technique for an extended posterior approach to the hip and pelvis that exposes the supra-acetabular ilium and preserves the glutei during revision hip surgery. Proximal to distal mobilisation of the gluteus medius from the posterior gluteal line permits exposure and mobilisation of the superior gluteal neurovascular bundle between the sciatic notch and the entrance to the gluteus medius, enabling a wider exposure of the supra-acetabular ilium. This technique was subsequently used in nine patients undergoing revision total hip replacement involving the reconstruction of nine Paprosky 3B acetabular defects, five of which had pelvic discontinuity. Intra-operative electromyography showed that the innervation of the gluteal muscles was not affected by surgery. Clinical follow-up demonstrated good hip abduction function in all patients. These results were compared with those of a matched cohort treated through a Kocher–Langenbeck approach. Our modified approach maximises the exposure of the ilium above the sciatic notch while protecting the gluteal muscles and their neurovascular bundle. Cite this article: Bone Joint J 2014;96-B:48–53

We retrospectively evaluated the clinical and radiological outcomes of a consecutive cohort of patients aged > 70 years with a displaced fracture of the olecranon, which was treated non-operatively with early mobilisation. We identified 28 such patients (27 women) with a mean age of 82 years (71 to 91). The elbow was initially immobilised in an above elbow cast in 90° of flexion of the elbow for a mean of five days. The cast was then replaced by a sling. Active mobilisation was encouraged as tolerated. No formal rehabilitation was undertaken. At a mean follow-up of 16 months (12 to 26), the mean ranges of flexion and extension were 140° and 15° respectively. On a visual analogue scale of 1 (no pain) to 10, the mean pain score was 1 (0 to 8). Of the original 28 patients 22 developed nonunion, but no patients required surgical treatment. . We conclude that non-operative functional treatment of displaced olecranon fractures in the elderly gives good results and a high rate of satisfaction. .

1. The results of three forms of treatment (mobilisation, immobilisation for six weeks, and suture with immobilisation for six weeks) for ruptures of the lateral ligament of the ankle have been compared in previously uninjured asymptomatic patients. 2. Only suture and immobilisation ensured final mechanical stability of the ankle as assessed by stress radiography. Unstable ankles were found after both mobilisation and immobilisation, but in these groups no ankle finally displayed more than 8 degrees of relative talar tilt. 3. The mean duration of disability in patients who finally became symptom-free was: after mobilisation, twelve weeks; after immobilisation, twenty-two weeks; and after suture and immobilisation, twenty-six weeks. 4. One year after injury 58 per cent of patients treated by mobilisation, 53 per cent of patients treated by immobilisation, but only 25 per cent of patients treated by suture and immobilisation, had become perfectly symptom-free. 5. For these reasons, and because simple sprains are satisfactorily treated by mobilisation, it is suggested that mobilisation may be the treatment of choice for most, perhaps all, ruptures of the lateral ligament of the ankle

We compared two conservative methods of treating Weber B1 (Lauge-Hansen supination-eversion 2) isolated fractures of the lateral malleolus in 65 patients. Treatment by immediate weight-bearing and mobilisation resulted in earlier rehabilitation than immobilisation for four weeks in a plaster cast. There was no significant difference in the amount of pain experienced or in the requirement for analgesics and early mobilisation was not associated with any complications. We therefore advocate early mobilisation for these stable ankle fractures

Aims. We assessed the difference in hospital based and early clinical outcomes between the direct anterior approach and the posterior approach in patients who undergo total hip arthroplasty (THA). Patients and Methods. The outcome was assessed in 448 (203 males, 245 females) consecutive patients undergoing unilateral primary THA after the implementation of an ‘Enhanced Recovery’ pathway. In all, 265 patients (mean age: 71 years (49 to 89); 117 males and 148 females) had surgery using the direct anterior approach (DAA) and 183 patients (mean age: 70 years (26 to 100); 86 males and 97 females) using a posterior approach. The groups were compared for age, gender, American Society of Anesthesiologists grade, body mass index, the side of the operation, pre-operative Oxford Hip Score (OHS) and attendance at ‘Joint school’. Mean follow-up was 18.1 months (one to 50). Results. There was no significant difference in mean length of stay (p = 0.07), pain scores on the day of surgery, the first, second and third post-operative days (p = 0.36, 0.23, 0.25 and 0.59, respectively), the day of mobilisation (p = 0.12), the mean OHS at six and 24 months (p = 0.08, and 0.29, respectively), the incidence of infection (p = 1.0), dislocation (p = 1.0), re-operation (p = 0.21) or 28 days’ re-admission (p = 0.06). Significantly more patients in the DAA group achieved a planned discharge target of three days post-operatively (68% vs 56%, p = 0.007). The rate of periprosthetic femoral fractures was significantly higher in the DAA group (p = 0.04). Conclusion. We conclude that there is no difference in clinical outcomes between the DAA and the posterior approach in patients undergoing THA when an ‘Enhanced Recovery’ pathway is used. However, a significantly higher rate of periprosthetic femoral fractures remains a concern with the DAA, even in experienced hands. Take home message: Our results show that the DAA for THA is not superior to posterior approach when ‘Enhanced Recovery’ pathway is used. Cite this article: Bone Joint J 2016;98-B:754–60

Fractures of the proximal interphalangeal joint include a wide spectrum of injuries, from stable avulsion fractures to complex fracture-dislocations. Stability of the joint is paramount in determining the appropriate treatment, which should aim to facilitate early mobilisation and restoration of function

We performed a prospective study on 96 patients with extra-articular or intra-articular fractures of the distal radius with a dorsally displaced posteromedial fragment. After closed reduction, we compared trans-styloid fixation and immobilisation with Kapandji fixation and early mobilisation. Forty-two patients of mean age 57.1 years +/- 18.1 (SD) were treated by trans-styloid K-wire fixation and 45 days of short-arm cast immobilisation. Fifty-four patients of mean age 57.7 years +/- 18.7 (SD) had Kapandji fixation and immediate mobilisation according to the originator. All the patients had clinical and radiological review at about six weeks and at 3, 6, 12 and 24 months after the operation. Pain, range of movement and grip strength were tested clinically, and changes in dorsal tilt, radial tilt, ulnar variance, and radial shortening were assessed radiologically. Statistical analysis was applied to comparisons with the normal opposite wrist. Pain and reflex sympathetic dystrophy were more frequent after Kapandji fixation and early mobilisation, but the range of motion was better although this became statistically insignificant after six weeks. The radiological reduction was better soon after Kapandji fixation, but there was some loss of reduction and increased radial shortening during the first three postoperative months. The clinical result at two years was similar in both groups

In light of the growing number of elderly osteopenic patients with distal humeral fractures, we discuss the history of their management and current trends. Under most circumstances operative fixation and early mobilisation is the treatment of choice, as it gives the best results. The relative indications for and results of total elbow replacement versus internal fixation are discussed

This review considers the surgical treatment of displaced fractures involving the knee in elderly, osteoporotic patients. The goals of treatment include pain control, early mobilisation, avoidance of complications and minimising the need for further surgery. Open reduction and internal fixation (ORIF) frequently results in loss of reduction, which can result in post-traumatic arthritis and the occasional conversion to total knee replacement (TKR). TKR after failed internal fixation is challenging, with modest functional outcomes and high complication rates. TKR undertaken as treatment of the initial fracture has better results to late TKR, but does not match the outcome of primary TKR without complications. Given the relatively infrequent need for late TKR following failed fixation, ORIF is the preferred management for most cases. Early TKR can be considered for those patients with pre-existing arthritis, bicondylar femoral fractures, those who would be unable to comply with weight-bearing restrictions, or where a single definitive procedure is required

This study compares the initial outcomes of minimally invasive techniques for single-event multi-level surgery with conventional single-event multi-level surgery. The minimally invasive techniques included derotation osteotomies using closed corticotomy and fixation with titanium elastic nails and percutaneous lengthening of muscles where possible. A prospective cohort study of two matched groups was undertaken. Ten children with diplegic cerebral palsy with a mean age of ten years six months (7.11 to 13.9) had multi-level minimally invasive surgery and were matched for ambulatory level and compared with ten children with a mean age of 11 years four months (7.9 to 14.4) who had conventional single-event multi-level surgery. Gait kinematics, the Gillette Gait Index, isometric muscle strength and gross motor function were assessed before and 12 months after operation. The minimally invasive group had significantly reduced operation time and blood loss with a significantly improved time to mobilisation. There were no complications intra-operatively or during hospitalisation in either group. There was significant improvement in gait kinematics and the Gillette Gait Index in both groups with no difference between them. There was a trend to improved muscle strength in the multi-level group. There was no significant difference in gross motor function between the groups. We consider that minimally invasive single-event multi-level surgery can be achieved safely and effectively with significant advantages over conventional techniques in children with diplegic cerebral palsy

Coronal plane fractures of the posterior femoral condyle, also known as Hoffa fractures, are rare. Lateral fractures are three times more common than medial fractures, although the reason for this is not clear. The exact mechanism of injury is likely to be a vertical shear force on the posterior femoral condyle with varying degrees of knee flexion. These fractures are commonly associated with high-energy trauma and are a diagnostic and surgical challenge. Hoffa fractures are often associated with inter- or supracondylar distal femoral fractures and CT scans are useful in delineating the coronal shear component, which can easily be missed. There are few recommendations in the literature regarding the surgical approach and methods of fixation that may be used for this injury. Non-operative treatment has been associated with poor outcomes. The goals of treatment are anatomical reduction of the articular surface with rigid, stable fixation to allow early mobilisation in order to restore function. A surgical approach that allows access to the posterior aspect of the femoral condyle is described and the use of postero-anterior lag screws with or without an additional buttress plate for fixation of these difficult fractures.

To date, all surgical techniques used for reconstruction of the pelvic ring following supra-acetabular tumour resection produce high complication rates. We evaluated the clinical, oncological and functional outcomes of a cohort of 35 patients (15 men and 20 women), including 21 Ewing’s sarcomas, six chondrosarcomas, three sarcomas not otherwise specified, one osteosarcoma, two osseous malignant fibrous histiocytomas, one synovial cell sarcoma and one metastasis. The mean age of the patients was 31 years (8 to 79) and the latest follow-up was carried out at a mean of 46 months (1.9 to 139.5) post-operatively. We undertook a functional reconstruction of the pelvic ring using polyaxial screws and titanium rods. In 31 patients (89%) the construct was encased in antibiotic-impregnated polymethylmethacrylate. Preservation of the extremities was possible for all patients. The survival rate at three years was 93.9% (95% confidence interval (CI) 77.9 to 98.4), at five years it was 82.4% (95% CI 57.6 to 93.4). For the 21 patients with Ewing’s sarcoma it was 95.2% (95% CI 70.7 to 99.3) and 81.5% (95% CI 52.0 to 93.8), respectively. Wound healing problems were observed in eight patients, deep infection in five and clinically asymptomatic breakage of the screws in six. The five-year implant survival was 93.3% (95% CI 57.8 to 95.7). Patients were mobilised at a mean of 3.5 weeks (1 to 7) post-operatively. A post-operative neurological defect occurred in 12 patients. The mean Musculoskeletal Tumor Society score at last available follow-up was 21.2 (10 to 27). This reconstruction technique is characterised by simple and oncologically appropriate applicability, achieving high primary stability that allows early mobilisation, good functional results and relatively low complication rates.

Early mobilisation after arthroplasty of the knee sometimes results in wound breakdown. The two commonly used incisions, the anterior midline and the medial parapatellar incisions, were compared in order to determine which had the best potential for wound healing. Study of the cleavage lines around the knee demonstrated that the medial parapatellar incision lies parallel to the lines, whilst the anterior midline incision lies perpendicular to them. In addition, the medial parapatellar wound was found to be subjected to significantly less tension during flexion; after arthroplasty it can be expected to heal faster and to be less liable to disruption during early mobilisation

Stable fixation after a corrective supracondylar osteotomy in adults is difficult because of the irregularity of the area of bony contact, displacement of the fragments, the predominance of cortical bone, and the need for early mobilisation. We have used the Ilizarov apparatus for fixation in 15 patients who were treated by complex osteotomies with displacement of fragments for cubitus varus or valgus. Most patients with cubitus varus required medial displacement with rotation of the distal fragment. Those with cubitus valgus required lateral shift of the distal fragment to reduce the medial prominence of the elbow that would otherwise result. All osteotomies united within the expected time without loss of correction, despite early mobilisation. Complications related to the fixation were few and had resolved at the long-term follow-up

The presence of the connective tissue components fibronectin and the different types of collagen was demonstrated by histological and immunohistological methods in the granulation and scar tissue of a healing injury in rat muscle. The effects of physical activity on granulation tissue production, scar formation and muscle regeneration at various stages of healing were studied. It was shown that immobilisation after injury accelerates granulation tissue production, but if continued too long, leads to contraction of the scar and to poor structural organisation of the components of regenerating muscle and scar tissue. However, a certain period of immobilisation, about five days for rat muscle, is required to allow newly-formed granulation tissue to cover the injured area and to have sufficient tensile strength to withstand subsequent mobilisation. This mobilisation, at the correct interval, seems essential for the quicker resorption of scar tissue and the better structural organisation of the muscle

We present a prospective study of patients with tuberculosis of the dorsal, dorsolumbar and lumbar spine after combined anterior (radical debridement and anterior fusion) and posterior (instrumentation and fusion) surgery. The object was to study the progress of interbody union, the extent of correction of the kyphosis and its maintenance with early mobilisation, and the incidence of graft and implant-related problems. The American Spinal Injury Association (ASIA) score was used to assess the neurological status. The mean preoperative vertebral loss was highest (0.96) in the dorsal spine. The maximum correction of the kyphosis in the dorsolumbar spine was 17.8°. Loss of correction was maximal in the lumbosacral spine at 13.7°. All patients had firm anterior fusion at a mean of five months. The incidence of infection was 3.9% and of graft-related problems 6.5%. We conclude that adjuvant posterior stabilisation allows early mobilisation and rehabilitation. Graft-related problems were fewer and the progression and maintenance of correction of the kyphosis were better than with anterior surgery alone. There is no additional risk relating to the use of an implant either posteriorly or anteriorly even when large quantities of pus are present

We studied prospectively 30 patients who had a Mitchell’s osteotomy secured by either a suture followed by immobilisation in a plaster boot for six weeks, or by a cortical screw with early mobilisation. The mean time for return to social activities after fixation by a screw was 2.9 weeks and to work 4.9 weeks, which was significantly earlier than those who had stabilisation by a suture (5.7 and 8.7 weeks, respectively; p < 0.001). Use of a screw also produced a higher degree of patient satisfaction at six weeks, and an earlier return to wearing normal footwear. The improvement in forefoot scores was significantly greater after fixation by a screw at six weeks (p = 0.036) and three months (p = 0.024). At one year, two screws had been removed because of pain at the site of the screw head. Internal fixation of Mitchell’s osteotomy by a screw allows the safe early mobilisation of patients and reduces the time required for convalescence

We report the outcomes of 20 patients (12 men, 8 women, 21 feet) with Charcot neuro-arthropathy who underwent correction of deformities of the ankle and hindfoot using retrograde intramedullary nail arthrodesis. The mean age of the patients was 62.6 years (46 to 83); their mean BMI was 32.7 (15 to 47) and their median American Society of Anaesthetists score was 3 (2 to 4). All presented with severe deformities and 15 had chronic ulceration. All were treated with reconstructive surgery and seven underwent simultaneous midfoot fusion using a bolt, locking plate or a combination of both. At a mean follow-up of 26 months (8 to 54), limb salvage was achieved in all patients and 12 patients (80%) with ulceration achieved healing and all but one patient regained independent mobilisation. There was failure of fixation with a broken nail requiring revision surgery in one patient. Migration of distal locking screws occurred only when standard screws had been used but not with hydroxyapatite-coated screws. The mean American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS-FAO) score improved from 50.7 (17 to 88) to 65.2 (22 to 88), (p = 0.015). The mean Short Form (SF)-36 Health Survey Physical Component Score improved from 25.2 (16.4 to 42.8) to 29.8 (17.7 to 44.2), (p = 0.003) and the mean Euroqol EQ‑5D‑5L score improved from 0.63 (0.51 to 0.78) to 0.67 (0.57 to 0.84), (p = 0.012). Single-stage correction of deformity using an intramedullary hindfoot arthrodesis nail is a good form of treatment for patients with severe Charcot hindfoot deformity, ulceration and instability provided a multidisciplinary care plan is delivered.

We compared case-mix and outcome variables in 1310 patients who sustained an acute fracture at the age of 80 years or over. A group of 318 very elderly patients (≥ 90 years) was compared with a group of 992 elderly patients (80 to 89 years), all of whom presented to a single trauma unit between July 2007 and June 2008. The very elderly group represented only 0.6% of the overall population, but accounted for 4.1% of all fractures and 9.3% of all orthopaedic trauma admissions. Patients in this group were more likely to require hospital admission (odds ratio 1.4), less likely to return to independent living (odds ratio 3.1), and to have a significantly longer hospital stay (ten days, p = 0.01). The 30- and 120-day unadjusted mortality was greater in the very elderly group. The 120-day mortality associated with non-hip fractures of the lower limb was equal to that of proximal femoral fractures, and was significantly increased with a delay to surgery > 48 hours for both age groups (p = 0.04). This suggests that the principle of early surgery and mobilisation of elderly patients with hip fractures should be extended to include all those in this vulnerable age group

We have reviewed 74 tuberculous hips in 73 children treated from 1950 to 1991. From 1979 to 1991 we treated 28 patients with rifampicin, isoniazid and pyrazinamide given for nine months (series A), using active mobilisation for the more recent cases. Before this, 46 hips had been treated with streptomycin and isoniazid with or without para-aminosalicyclic acid given for a mean of 18 months (series B), and all these patients were immobilised for a mean of 2.2 years. The radiological appearances at presentation as classified by Shanmugasundaram (1983) predicted the outcome. Most hips were of the 'normal' type (50% and 59% of series A and B respectively) followed by the dislocating type (25% and 13%) and the atrophic type (8% and 9%). There were good or excellent results in 93% of the 'normal' type. All the atrophic type had poor results. The dislocating type had a poor result if the joint space was narrow after reduction of the hip. Early mobilisation had no effect on the outcome of the 'normal' type of disease. The newer drug regimens allowed for shorter courses of treatment, but did not necessarily give a better outcome

We report a retrospective review of the incidence of venous thromboembolism in 463 consecutive patients who underwent primary total hip arthroplasty (487 procedures). Treatment included both total hip replacement and hip resurfacing, and the patients were managed without anticoagulants. The thromboprophylaxis regimen included an antiplatelet agent, generally aspirin, hypotensive epidural anaesthesia, elastic compression stockings and early mobilisation. In 258 of these procedures (244 patients) performed in 2005 (cohort A) mechanical compression devices were not used, whereas in 229 (219 patients) performed during 2006 (cohort B) bilateral intermittent pneumatic calf compression was used. All operations were performed through a posterior mini-incision approach. Patients who required anticoagulation for pre-existing medical problems and those undergoing revision arthroplasty were excluded. Doppler ultrasonographic screening for deep-vein thrombosis was performed in all patients between the fourth and sixth post-operative days. All patients were reviewed at a follow-up clinic six to ten weeks after the operation. In addition, reponse to a questionnaire was obtained at the end of 12 weeks post-operatively. No symptomatic calf or above-knee deep-vein thrombosis or pulmonary embolism occurred. In 25 patients in cohort A (10.2%) and in ten patients in cohort B (4.6%) asymptomatic calf deep-vein thromboses were detected ultrasonographically. This difference was statistically significant (p = 0.03). The regimen followed by cohort B offers the prospect of a low incidence of venous thromboembolism without subjecting patients to the higher risk of bleeding associated with anticoagulant use

Surgical access to the head of the radius is usually performed through a lateral approach. We present an alternative technique through a modified posterior approach which was developed following dissections of 22 human cadavers. An osteotomy of the supinator tuberosity was performed and reflected as a single unit with the attached annular ligament. Excellent exposure of the head of the radius was achieved, replacement of the head was undertaken and the osteotomy site repaired. The elbows were stable and had a full range of movement. The approach was then carried out on 13 patients for elective replacement of the head and was found to be safe and reproducible. In the patient group all osteotomies united, the elbows were stable and had an improved range of supination and pronation. There was no change in flexion and extension of the elbow. Complications included a haematoma and a reflex sympathetic dystrophy. The modified posterior approach provides excellent access to the head and neck of the radius, gives good stability of the elbow and allows early mobilisation of the joint

This population-based study investigated the incidence and trends in venous thromboembolic disease after total hip and knee arthroplasty over a ten-year period. Death or readmission for venous thromboembolic disease up to two years after surgery for all patients in Scotland was the primary outcome. The incidence of venous thromboembolic disease, including fatal pulmonary embolism, three months after surgery was 2.27% for primary hip arthroplasty and 1.79% for total knee arthroplasty. The incidence of fatal pulmonary embolism within three months was 0.22% for total hip arthroplasty and 0.15% for total knee arthroplasty. The majority of events occurred after hospital discharge, with no apparent trend over the period. The data support current advice that prophylaxis should be continued for at least six weeks following surgery. Despite the increased use of policies for prophylaxis and earlier mobilisation, there has been no change in the incidence of venous thromboembolic disease

We treated 26 hips (24 consecutive patients) with residual dysplasia by a technique of incomplete triple pelvic osteotomy. The mean age of the patients was 21.6 years. The mean values for the pre-operative centre-edge angle of Wiberg, the refined centre-edge angle, the acetabular angle of Sharp, the modified acetabular angle and femoral head lateralisation were 7.7°, −3.1°, 49.3°, 53.2° and 17.2 mm, respectively. After a mean follow-up of 3.3 years they were 27.0°, 13.0°, 38.9°, 44.3° and 15.9 mm, respectively (p < 0.05). The osteoarthritic grading changed adversely in one hip. The mean pre-operative and latest Harris hip scores were 74.9 and 93.0, respectively (p < 0.05). This technique provides a stable osteotomy with maintenance of the posterior column which allows early mobilisation and minimal internal fixation. The technique is not complex and requires minimal blood transfusion. The use of an image intensifier is not necessary and harvesting of a subcristal bone graft avoids post-operative complications at the donor site

This paper describes the technique and results of an acetabuloplasty in which the false acetabulum is turned down to augment the dysplastic true acetabulum at its most defective part. This operation was performed in 17 hips (16 children), with congenital dislocation and false acetabula. The mean age at operation was 5.1 years (4 to 8). The patients were followed clinically and radiologically for a mean of 6.3 years (5 to 10). A total of 16 hips had excellent results and there was one fair result due to avascular necrosis. The centre-edge angles and the obliquity of the acetabular roof improved in all cases, from a mean of −15.9° (−19° to 3°) and 42.6° (33° to 46°) to a mean of 29.5° (20° to 34°) and 11.9° (9° to 19°), respectively. The technique is not complex and is stable without internal fixation. It provides a near-normal acetabulum that requires minimal remodelling, and allows early mobilisation

We compared the outcome of patients treated for an intertrochanteric fracture of the femoral neck with a locked, long intramedullary nail with those treated with a dynamic hip screw (DHS) in a prospective randomised study. Each patient who presented with an extra-capsular hip fracture was randomised to operative stabilisation with either a long intramedullary Holland nail or a DHS. We treated 92 patients with a Holland nail and 98 with a DHS. Pre-operative variables included the Mini Mental test score, patient mobility, fracture pattern and American Society of Anesthesiologists grading. Peri-operative variables were anaesthetic time, operating time, radiation time and blood loss. Post-operative variables were time to mobilising with a frame, wound infection, time to discharge, time to fracture union, and mortality. We found no significant difference in the pre-operative variables. The mean anaesthetic and operation times were shorter in the DHS group than in the Holland nail group (29.7 vs 40.4 minutes, p < 0.001; and 40.3 vs 54 minutes, p < 0.001, respectively). There was an increased mean blood loss within the DHS group versus the Holland nail group (160 ml vs 78 ml, respectively, p < 0.001). The mean time to mobilisation with a frame was shorter in the Holland nail group (DHS 4.3 days, Holland nail 3.6 days, p = 0.012). More patients needed a post-operative blood transfusion in the DHS group (23 vs seven, p = 0.003) and the mean radiation time was shorter in this group (DHS 0.9 minutes vs Holland nail 1.56 minutes, p < 0.001). The screw of the DHS cut out in two patients, one of whom underwent revision to a Holland nail. There were no revisions in the Holland nail group. All fractures in both groups were united when followed up after one year. We conclude that the DHS can be implanted more quickly and with less exposure to radiation than the Holland nail. However, the resultant blood loss and need for transfusion is greater. The Holland nail allows patients to mobilise faster and to a greater extent. We have therefore adopted the Holland nail as our preferred method of treating intertrochanteric fractures of the hip

We have reviewed 20 women and three men aged 22 to 73 years, who had sustained a Mason type-IIb fracture of the neck of the radius 14 to 25 years earlier. There were 19 patients with displacement of the fractures of 2 mm to 4 mm, of whom 13 had been subjected to early mobilisation and six had been treated in plaster for one to four weeks. Of four patients with displacement of 4 mm to 8 mm, three had undergone excision and one an open reduction of the head of radius. A total of 21 patients had no subjective complaints at follow-up, but two had slight impairment and occasional elbow pain. The mean range of movement and strength of the elbow were not impaired. The elbows had a higher prevalence of degenerative changes than the opposite side, but no greater reduction of joint space. Mason type-IIb fractures have an excellent long-term outcome if operation is undertaken when the displacement of the fracture exceeds 4 mm

Secure fixation of displaced proximal fractures of the humerus is a challenging problem. A total of 32 patients with acutely displaced three- or four-part proximal fractures of the humerus were treated by open reduction and internal fixation using the proximal humeral internal locking system (PHILOS) plate. There were 23 women and nine men with a mean age of 59.9 years (18 to 87). Data were collected prospectively and the outcomes were assessed using the Constant score. The mean follow-up was for 11 months (3 to 24). In 31 patients (97%) the fracture united clinically and radiologically at a mean of 10 weeks (8 to 24). The mean Constant score at final review was 66.5 (30 to 92). There was no significant difference in outcome when comparing patients aged more than 60 years (18 patients) with those aged less than 60 years (14 patients) (t-test, p = 0.8443). There was one case each of nonunion, malunion and a broken screw in the elderly population. This plate provides an alternative method of fixation for fractures of the proximal humerus. It provides a stable fixation in young patients with good-quality bone sufficient to permit early mobilisation. Failure of the screws to maintain fixation in the elderly remains a problem

We retrospectively reviewed the operative treatment carried out between 1988 and 1994 of eight patients with habitual patellar dislocation. In four the condition was bilateral. All patients had recurrent dislocation with severe functional disability. The surgical technique involved distal advancement of the patella by complete mobilisation of the patellar tendon, lateral release and advancement of vastus medialis obliquus. The long-term results were assessed radiologically, clinically and functionally using the Lysholm knee score, by an independent observer. The mean age at operation was 10.3 years (7 to 14) with a mean follow-up of 13.5 years (11 to 16). One patient required revision. At the latest follow-up, all patellae were stable and knees functional with a mean Lysholm knee score of 98 points (95 to 100). In those aged younger than ten years at operation there was a statistically significant improvement in the sulcus angle at the latest follow-up (Student’s t-test, p = 0.001). Two patients developed asymptomatic patella infera as a late complication. This technique offers a satisfactory treatment for the immature patient presenting with habitual patellar dislocation associated with patella alta. If performed early, we believe that remodelling of the shallow trochlea may occur, adding intrinsic patellofemoral stability

We present the results of the surgical correction of lower-limb deformities caused by metabolic bone disease. Our series consisted of 17 patients with a diagnosis of hypophosphataemic rickets and two with renal osteodystrophy; their mean age was 25.6 years (14 to 57). In all, 43 lower-limb segments (27 femora and 16 tibiae) were osteotomised and the deformity corrected using a monolateral external fixator. The segment was then stabilised with locked intramedullary nailing. In addition, six femora in three patients were subsequently lengthened by distraction osteogenesis. The mean follow-up was 60 months (18 to 120). The frontal alignment parameters (the mechanical axis deviation, the lateral distal femoral angle and the medial proximal tibial angle) and the sagittal alignment parameters (the posterior distal femoral angle and the posterior proximal tibial angle) improved post-operatively. The external fixator was removed either at the end of surgery or at the end of the lengthening period, allowing for early mobilisation and weight-bearing. We encountered five problems and four obstacles in the programme of treatment. The use of intramedullary nails prevented recurrence of deformity and refracture

The use of volar locking compression plates for the treatment of fractures of the distal radius is becoming increasingly popular because of the stable biomechanical construct, less soft-tissue disturbance and early mobilisation of the wrist. A few studies have reported complications such as rupture of flexor tendons. We describe three cases of rupture of extensor tendons after the use of volar locking compression plates. We recommend extreme care when drilling and placing the distal radial screws to prevent damaging the extensor tendons

We report the results of treatment with the dynamic condylar screw of 21 cases of supracondylar and intercondylar fractures of the femur in patients aged 22 to 91 years. There were two nonunions and no deaths. We found the device easy to use and the good fixation allowed early patient mobilisation

We treated 19 patients with established nonunion of the radius and/or ulna by the excision of avascular bone and the grafting of blocks of corticocancellous bone from the iliac crest, augmented by rigid plate fixation under compression. This allowed early mobilisation, and bony union was achieved between three and 24 months after operation in all but one of the patients. The single failure was attributed to the excessive length of the defect (100 mm) and inadequate fixation

We dissected 20 cadaver hips in order to investigate the anatomy and excursion of the trochanteric muscles in relation to the posterior approach for total hip replacement. String models of each muscle were created and their excursion measured while the femur was moved between its anatomical position and the dislocated position. The position of the hip was determined by computer navigation. In contrast to previous studies which showed a separate insertion of piriformis and obturator internus, our findings indicated that piriformis inserted onto the superior and anterior margins of the greater trochanter through a conjoint tendon with obturator internus, and had connections to gluteus medius posteriorly. Division of these connections allowed lateral mobilisation of gluteus medius with minimal retraction. Analysis of the excursion of these muscles revealed that positioning the thigh for preparation of the femur through this approach elongated piriformis to a maximum of 182%, obturator internus to 185% and obturator externus to 220% of their resting lengths, which are above the thresholds for rupture of these muscles. Our findings suggested that gluteus medius may be protected from overstretching by release of its connection with the conjoint tendon. In addition, failure to detach piriformis or the obturators during a posterior approach for total hip replacement could potentially produce damage to these muscles because of over-stretching, obturator externus being the most vulnerable

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
