Background. Pleural drains are routinely used following anterior approaches to the spine for the correction of spinal deformities, to prevent the accumulation of blood, fluids and air in the pleural cavity. Following their removal it is routine practise in our Trust to obtain chest radiographs to look out for a pneumothorax or a residual fluid collection. Our hypothesis is that unless clinically indicated the use of a CXR does not affect patient management and should not therefore be routine practice. Methods. A retrospective audit of 122 consecutive patients, who underwent surgery for the correction of spinal deformity using an anterior approach to the spine, over the course of a year, was undertaken. CXRs were performed in all patients following drain removal. We have reviewed those images and in cases were abnormalities were detected we have examined the case notes to assess the impact of those findings with regards to management. Results. 122 patients (92F,30M) were included in our study. Mean age was 20.1 yyears. There were records of pre existing lung pathology in 4 cases. The right and left pleura were opened in 99 and 23 cases respectively and a chest drain was inserted in all cases peri operatively. The average time for removal was 4.2 days. There were 27 cases were an insignificant abnormality was detected. There were 2 cases were a large pneumothorax (>2cm) was detected. On reviewing these case notes there were abnormalities in clinical parameters and abnormal findings on clinical examination that would alert the clinician to the possibility of underlying pathology and the need for further evaluation. In all cases there was no further intervention in the form of chest drain re insertion. Conclusion. There is a very low incidence of pneumothorax following pleural drain removal. Those cases can be identified by means of clinical evaluation. The use of routine CXR is not necessary. This is a safe cost effective intervention that will also serve to reduce the radiation patients are subjected to. Ethics approval Audit/service standard in trust. Interest StatementNone

Aims

A single-centre prospective randomized trial was conducted to investigate whether a less intensive follow-up protocol would not be inferior to a conventional follow-up protocol, in terms of overall survival, in patients who have undergone surgery for sarcoma of the limb. Initial short-term results were published in 2014.

Thoracic hyperkyphosis (TH – Cobb angle >40°) is correlated with rotator cuff arthropathy and associated with anterior tilting and protraction of scapula, impacting the glenoid orientation and the surrounding musculature. Reverse total shoulder arthroplasty (RTSA) is a reliable surgical treatment for patients with rotator cuff arthropathy and recent literature suggests that patients with TH may have comparable range of motion after RTSA. However, there exists no study reporting the possible link between patient-reported outcomes, humeral retroversion and TH after RTSA. While the risk of post-operative complications such as instability, hardware loosening, scapular notching, and prosthetic infection are low, we hypothesize that it is critical to optimize the biomechanical parameters through proper implant positioning and understanding patient-specific scapular and thoracic anatomy to improve surgical outcomes in this subset of patients with TH. Patients treated with primary RTSA at an academic hospital in 2018 were reviewed for a two-year follow-up. Exclusion criteria were as follows: no pre-existing chest radiographs for Cobb angle measurement, change in post-operative functional status as a result of trauma or medical comorbidities, and missing component placement and parameter information in the operative note. As most patients did not have a pre-operative chest radiograph, only seven patients with a Cobb angle equal to or greater than 40° were eligible. Chart reviews were completed to determine indications for RTSA, hardware positioning parameters such as inferior tilting, humeral stem retroversion, glenosphere size/location, and baseplate size. Clinical data following surgery included review of radiographs and complications. Follow-up in all patients were to a period of two years. The American Shoulder and Elbow Surgeons (ASES) Shoulder Score was used for patient-reported functional and pain outcomes. The average age of the patients at the time of RTSA was 71 years old, with six female patients and one male patient. The indication for RTSA was primarily rotator cuff arthropathy. Possible correlation between Cobb angle and humeral retroversion was noted, whereby, Cobb angle greater than 40° matched with humeral retroversion greater than 30°, and resulted in significantly higher ASES scores. Two patients with mean Cobb angle of 50° and mean humeral retroversion 37.5° had mean ASES scores of 92.5. Five patients who received mean humeral retroversion of 30° had mean lower ASES scores of 63.7 (p < 0 .05). There was no significant correlation with glenosphere size or position, baseplate size, degree of inferior tilting or lateralization. Patient-reported outcomes have not been reported in RTSA patients with TH. In this case series, we observed that humeral stem retroversion greater than 30° may be correlated with less post-operative pain and greater patient satisfaction in patients with TH. Further clinical studies are needed to understanding the biomechanical relationship between RTSA, humeral retroversion and TH to optimize patient outcomes

Objectives. In this cross sectional study, the impact and the efficacy of a surveillance programme for sarcomas of the extremities was analysed. Methods. All patients who had treatment with curative intent for a high-grade sarcoma and were diagnosed before 2014 were included and followed for a minimum of two years. Results. Of the 909 patients who had a review appointment in 2014, 131 were under review for a high-grade sarcoma of the extremities following treatment with curative intent. Of these patients, three patients died of disease, two patients died of other causes, 12 are alive, with disease, and 114 have no evidence of disease. The surveillance programme accounts for 14% of all review appointments. Four of five patients (80%) who developed local recurrence identified the recurrence themselves. Chest radiographs are adequate in identifying metastatic disease and 11 (73%) of metastases were diagnosed during a routine follow up visit. However, the chance of cure is small and only two patients were referred for a metastatectomy. Of these only one survived for more than two years. The mean time for developing metastatic disease and local recurrence was 2.0 and 3.9 years respectively. Once identified, the mean time to death was 2.1 years for patients with metastatic disease. Conclusions. Surveillance of sarcoma patients makes up a substantial amount of the workload of a sarcoma unit. The chance of cure following identification of local recurrence or metastatic disease, however, is small. Alternative methods of surveillance that allow better evaluation of the patient’s needs are recommended. Cite this article: P. Cool, G. Cribb.

There are limited data on scoliosis in cystic fibrosis (CF), and the two most recent studies came to opposite conclusions. Reported prevalence ranges from 2% (within the normal range for the general population) to 15.5%. We felt that a recent study under-estimated the prevalence due to a very young population (mean age 10.9 years), since scoliosis develops most commonly in adolescents. We hypothesised that scoliosis is more prevalent in adolescents with CF compared to the general population. The aim of our study was to determine the incidence of scoliosis in adolescents with CF followed to and beyond skeletal maturity and describe the type of spinal deformity. We included all patients in our CF clinic aged >10 years, and those who have transitioned to adult services in the last 10 years. Patients with a co-existent neuromuscular condition were excluded. We conducted a retrospective observational study. Most recent chest radiographs at end of spinal growth, or those taken at transition to adult services, were reviewed by a Consultant Radiologist and a Consultant Spine Surgeon. Scoliosis was defined as a Cobb angle of >10° in the coronal plane. Demographics and characteristics of the curves were recorded. Our cohort included 143 CF patients (48% male) with a mean age at the time of chest radiograph of 18 years (range 15–22 years). 16 (6 male) subjects were noted to have scoliosis with a mean (range) Cobb angle of 14° (10–38°) giving a prevalence of 11%. 13 were single thoracic curves, 2 double and 1 triple. The majority were non-progressive short mid-thoracic curves, convex to the right. 5 curves were progressive, only one of which was significant and required bracing to the end of growth but no surgical treatment. We found a prevalence of scoliosis in our adolescent CF population that is significantly greater than the general population. Only one curve was significant and progressive requiring bracing, the remainder being minor and non-progressive. A strength of our study is that all patients had achieved skeletal maturity at the time of latest X-ray and, therefore, development or further progression of scoliosis is unlikely. The negative effect of scoliosis on lung function is well-documented. With the progressive nature of CF lung disease, scoliosis may have further deleterious effects. Bone disease is increasingly recognised in CF patients, with osteopenia and osteoporosis occurring earlier and more frequently than in the general population (38% & 24% respectively in 18–32 year old CF patients). To date, studies have failed to show a correlation between scoliosis, lung function and bone mineral density. The paradigm of a radiologically significant (Cobb angle >10°) versus a clinically important scoliosis remains

Aim. Assess symptoms and diagnostic problems of chest wall chondrosarcoma and factors related to long doctor's delay. Methods. The material included all 106 consecutive patients with chondrosarcoma of the chest wall diagnosed in Sweden 1980-2002. Pathological specimens were re-evaluated and graded by the Scandinavian Sarcoma Group pathology board. Files from the very first medical visit for symptoms related to the chondrosarcoma were traced and used to characterise the initial symptoms, calculate patient's and doctor's delay and to identify factors contributing to the delays. Results. The most prominent initial symptom was a palpable mass found in (73/106) 69 % of the patients at the first visit. A tumour was suspected at the first visit in 85 % of the patients. Patients delay was in median 3 (0-118) months and doctor's delay was 4 (0.1-190) months. Doctor's delay was > 6 months for 40 % of the patients. Patients with an initial plain chest radiograph interpreted as normal (34 patients), and/or normal or inconclusive results of a fine-needle aspiration biopsy had longer doctor's delay. Fine-needle aspiration biopsy done at non-specialty units resulted in only 26 % correct malignant diagnoses; at sarcoma centres 94 % were correctly diagnosed. Only 57 % of the patients were operated at a sarcoma centre and 43 % at non-specialty hospitals. The local recurrence rate was 16 % and 57 %, respectively. The 10 years survival for patients treated at sarcoma centres was 75 % but only 59 % for those not referred. Conclusion. Chest wall chondrosarcoma presents as a lump, usually painless. Plain chest radiographs and fine-needle aspiration, when done at non-specialty hospitals are often normal or inconclusive. The diagnostic difficulties led to long doctor's delay and to inadequate treatment leading to poor outcome. Patients should be referred to sarcoma centres for diagnosis and treatment

Introduction: Well-differentiated liposarcomas have a tendency to recur locally but do not metastasise unless dedifferentiation occurs. In this study, a tumour superficial to the deep fascia of the trunk or limb is termed an atypical lipoma (AL) and one deep to fascia, a lipoma-like liposarcoma (LL) reflecting increased difficulty in wide local excision. Methods: We prospectively collected data for 87 well-differentiated liposarcomas excised at our institution from 1998–2008. Data was recorded on a multidisciplinary team database and verification was undertaken using patient records. Any radiological investigation performed was determined retrospectively. Primary excisions performed elsewhere were excluded. The aim was to produce recommendations on the clinical and radiographical post-operative management of these common tumours. Results: LL was seen in 74 patients and AL in 13 (mean age 58 years, mean follow up 5 years). The mean size of LL excisional biopsy was 148mm and 54mm for AL (p< 0.05). There were no AL recurrences. Five LL (7%) locally recurred within a mean of 5 years (range 2–10 years). All were deeply related to neurovascular structures (4 thigh-marginal/complete excisions and 1 upper arm-piecemeal excision). One recurrence was detected by MRI from 26 LL patients (35%), the other four being clinically suspected prior to re-scanning. During follow up, a chest radiograph was performed in 21 LL patients (27%) and no metastases were detected. Discussion: Patients with a completely excised superficial AL need no routine follow up. Follow up of LL is determined by the patient, the tumour size and the location. The routine use of interval MRI to detect local recurrence of uncomplicated LL is not necessary. MRI provides ‘base-line’ post-operative information where a neurovascular bundle was closely related to the tumour or excision was incomplete. Chest radiographs are not indicated in screening for metastases in these tumours unless locally recurrent

We retrospectively reviewed eight children with idiopathic chondrolysis (IC) of the hip and nine with atrophic tuberculosis (TB) of the hip treated over the 10 years 1990 to 1999. Both conditions present with a stiff hip and radiographic joint space narrowing. Our aim was to delineate clinical, radiological and histological differences between the two conditions, thereby obviating the need for biopsy in IC, which could worsen the prognosis. In the IC group all patients were girls. Their mean age was 12 years (11.5 to 13). They presented with a flexion abduction and external rotation deformity of the hip. Chest radiographs were normal in all patients, and all except one had an ESR below 20. The Mantoux was negative in six of the eight. Radiographs showed joint space narrowing and osteopoenia, but the subchondral bony line remained present. Four of the eight had a synovial biopsy, which showed non-specific chronic synovitis. The cartilage looked pale and lustreless. In one hip the cartilage was biopsied and showed cartilage necrosis. In the TB group, five of the nine patients were boys. The mean age was 7 years (5 to 13.5). The only constant hip deformity was flexion. Chest radiographs were normal in all patients. In all patients the ESR was below 20 and the Mantoux was positive. Hip radiographs showed osteopoenia with loss of the subchondral bony line. Peri-articular lytic lesions were present in all patients except one. Histology of synovial biopsy showed caseous necrosis in all hips, and seven of the nine had a positive culture for TB. Macroscopically the cartilage looked normal, and in one hip the cartilage biopsy was histologically normal. We confirmed that in IC the joint space narrowing is due to cartilage necrosis. We postulate that in atrophic TB the loss of subchondral bone due to subchondral erosion gives the impression of joint space narrowing. We also concluded that IC was a diagnoses per se and not by exclusion, and that biopsy was not required

Skeletal Cryptococcosis although rare has been reported in immunodeficient individuals and in particular those with HIV. We present a case in a HIV- negative patient who presented to the London Sarcoma service masquerading as a primary bone tumour and review the relevant literature. A 71 year old lady presented with a three month history of right submammary pain associated with a new lump. Chest radiographs showed an osteolytic lesion in the right 6. th. rib. CT scans demonstrated mediastinal lymphadenopathy and numerous lung nodules. Differential diagnosis of the lesion included TB abscess, myeloma, lymphoma or as a primary lung tumour presenting with hilar lymphadenopathy and necrotic skeletal metastasis. CT guided biopsy was performed with histology showing necrotising granulomatous inflammation with numerous yeast like organisms in keeping with Cryptococcus fungal infection. She was treated successfully with a six week course of voriconazole. Cryptococcal skeletal infections can cause significant morbidity and mortality and should be considered as a rare cause of lytic osseous lesions

We report a case of fatal heart failure caused by cobalt intoxication after revision THR in the patient who successfully underwent re-revision THR. 53-year old male presented to emergency room in our hospital with progressive shortness of breath. Symptom was started about 6 months ago so he visited local hospital. He worked up for worsening dyspnea. Simple chest radiograph and enhanced heart MRI study were performed and they showed bilateral pericardial and pleural effusion. There was no evidence of ischemic change. Transthoracic echocardiogram showed the evidence of heart failure, left ventricular ejection fraction(EF) was 40%. He was admitted at local hospital and started on vasopressors but urine output was decreased and follow-up echocardiogram showed a 25% of EF. Patient recommended heart transplantation and transferred our hospital emergency room. He underwent sequential bilateral total hip arthroplasties using CoP bearing surfaces. At 12 years postoperatively, he presented to the other hospital with acute onset of left hip pain. He was diagnosed ceramic head fracture on his left hip. Head and liner change revision surgery was performed using Cobalt-Chrome alloy 28mm metal head and Protruded cross-linked polyethylene liners. In our hospital, the patient admitted cardiovascular department of internal medicine. Patient complained nonspecific fatigue and general weakness but had no other symptoms such as visual and hearing loss, cognitive dysfuction. During work-up, patient presented progressive left hip pain and complaint of discomfort for the mass on the left groin. He also complained Left leg weakness and numbness. Simple radiograph and enhanced CT study was done. Simple radiograph image shows radiodense area around the hip joint and radiologist suspected heterotopic ossification. The cardiovascular department consulted orthopedic department. In the image findings showed huge mass combined hemorrhagic component lining acetabular component extending psoas compartment and eccentric wear on cobalt-chrome alloy metal head. Also highly radiodense material was seen around neck inferor portion and severly deformed metal head was seen. It was highly suspected that metal related granuloma, which means severe metallosis. Performed heavy metals screen, cobalt levels were 397,800 μg/Land chrome levels were 236,000 μg/L suggesting cobalt toxicity. Hip joint aspiration was done for decompression as radiologic intervention and EDTA (ethylenediamine tetraacetate) chelation therapy started immediately. After 10 cycle chelating therapy, metal level was lowered cobalt levels by 255.2μg/L and chrome levels by 39.5 μg/L. When hospital day after 134, Medical condition of the patient was getting improved, we underwent revision surgery using ceramic on ceramic bearing surface. The patient discharged postoperative 79 days. Final heavy metals screen results were 27.79μg/L on cobalt and 22.17μg/L on chrome. Although there were also reported a good clinical result of revision surgery using MoP bearing, and some surgeons reluctant to use CoC articulation because of concerns about re-fracture of ceramic. But take into account like this devastating complication after cobalt-chrome wear caused by remained ceramic particles, we should carefully select which bearing is safer

Twelve cases of sternal injury associated with spinal fractures have been reviewed. The sternum is regularly buckled or fractured in patients with high thoracic spinal fractures. Our review suggests that sternal injuries may also be associated with spinal fractures outside this region, and with types of fracture other than crushing of vertebral bodies. Injury to the sternum, when due to indirect violence, is almost always associated with a severe spinal column injury. A displaced fracture of the thoracic spine, with or without an associated sternal fracture, can produce significant widening of the mediastinal shadow on a chest radiograph. This is caused by a paravertebral haematoma, and can be difficult to differentiate from widening due to an aortic rupture

Purpose: The purpose of this study was to determine how patients with soft tissue sarcoma are followed up in the United Kingdom to inform the development of a prospective clinical trial. Methods: A list of clinicians (surgeons and oncologists) treating patients with soft tissue sarcomas in the United Kingdom was compiled and a postal survey performed. Reminders were sent to non-responders. The survey included questions about the specialty of the clinician, the grade, membership of specialist societies, perceptions about risk factors for recurrence and the value of follow up and asked specifically about three clinical scenarios. Results: Of 192 clinicians who were sent the questionnaire, responses were obtained from 155 (81%). 128 of these met the criteria for analysis. In the given clinical scenarios, length of follow up varied from 1 year to lifelong. The total number of clinic visits in 5 years varied from 5 to 30, of chest radiographs from 0 to 24, of chest CT scans from 0 to 10, and of local site imaging from 0 to 13. 88 (84%) agreed that follow up is of benefit. 57 (59%) agreed that it would be reasonable to follow up selected patients in the community. 96 (93%) agreed that a study of follow up protocols would be of value. Discussion: There is significant variation in follow-up protocols amongst clinicians in the United Kingdom. A prospective study of follow-up protocols is likely to be supported

Introduction. The assessment of the accuracy of reduction of the ankle syndesmosis has traditionally been made using plain radiographic measurements. Recent studies have shown that computerized tomography (CT) scan is more sensitive than radiographs in detecting diastasis. The ethos has now therefore shifted towards CT scan assessment of the syndesmosis. There is however no validated method to scan the syndesmosis and measure it on the CT scans. This exposes the patient to significant radiation risk and also to anxiety from inappropriate interpretation from these scans. The objectives of this research project are to investigate the current practice of CT scanning the syndesmosis at a University Hospital and to devise a new CT protocol to reduce radiation exposure to patients and to assist surgeons in interpreting the observations. Methods. Research Ethics Committee approval was obtained. Current practice was evaluated. A new 5 cut CT protocol was devised. Starting at the level of the distal tibial plafond, 5 cuts were made proximally 0.5 cm apart. Accuracy of the syndesmosis reduction was assessed just above the distal tibial plafond. Both the injured and the normal sides were scanned 12 weeks post surgery. The normal side served as a control. Results. Current practice revealed that patients had on an average 620 cuts CT scan with radiation exposure of 0.2 mSv. 25 patients were prospectively recruited for the new 5 cut CT protocol. The radiation exposure with the new protocol was only 0.002 mSv. Comparison with the normal side revealed that 5 (20%) of syndesmosis had residual diastasis. The only difficulty with the new protocol was getting both the ankle joint lines at the same level for the first CT cut. Discussion and Conclusion. Our CT scan protocol has insignificant radiation risk, even lower than a single chest radiograph. Comparing the measurements between the fractured and the normal sides provides an accurate assessment of the reduction of the syndesmosis. Significance of the measurements on the CT scan will be correlated with functional scores

Introduction and purpose: The relationship between congenital heart disease and the increased prevalence of scoliosis is well known, although the same cannot be said about the etiology of scoliosis in these patients. Although thoracotomy is often associated to scoliosis, median sternotomy has so far not been identified as an etiological agent. he purpose of the study is to determine if patients with congenital heart disease who are subjected to a median sternotomy show a higher prevalence of spine deformities. Materials and methods: A retrospective review is made of patients operated on for congenital heart disease through median sternotomy before the age of 8, assessing the development of spine deformities. Simple chest radiographs of 128 patients were studied once they reached skeletal maturity and it was observed that they presented no spinal or costal deformities before surgery. Results: The prevalence of scoliosis was 34.3%; 16 of these patients (12.5%) had curves of more than 20° and 33 (25.8%) had thoracic kyphosis of less than 20°. Patients operated on before the age of 18 months had a significantly higher risk to develop scoliosis as compared with those treated later (odds ratio: 3.48; p=0.016). The development of scoliosis was not related with the type of cardiac malformation present. Conclusions: There is a high prevalence of scoliosis in patients subjected to a median sternotomy for a congenital heart pathology. The prevalence of scoliosis increases in patients operated on at younger ages

We retrospectively reviewed 10 children treated for tuberculosis of the elbow over a 21-year period from 1979 to 1999. The mean age at diagnosis was 5.5 years (1 to 11). The median duration of symptoms was 10 weeks (l week to 18 months). The patients presented mainly with swelling of the elbow joint due to synovitis. Radiological appearances of the elbow at presentation were assessed according to Kerri and Martini’s classification. One elbow was stage I (osteopoenia), eight were stage II (osteopoenia and erosions) and one stage III (joint space narrowing). Open biopsy was performed on all patients. There was positive histology (caseating granuloma) and/or positive culture in eight patients. Of the two patients with non-specific histology and negative culture, one was found on chest radiograph to have tuberculosis involvement and the other healed on anti-tuberculosis therapy. All patients were treated with rifampicin, isoniazide and pyrazinamide for nine months. No synovectomy was done. Postoperatively all patients were immobilised in a backslab and then actively mobilised. At a mean follow-up of three years (1 to 10), patients were assessed according to a modification of Kerri and Martini’s classification. Seven of the eight stage-I or stage-II patients had an excellent result (full range of movement) or good result (loss of less than 30% of range of movement). One stage-II patient had a fair result (loss of range of movement of 30% to 50%). The stage-III patient had a poor result (loss of more than 50% of range of movement). We concluded that elbows with stage-I and stage-II disease (synovitis) have a good outcome. Anti-tuberculosis chemotherapy is effective in the treatment of stage-I and stage II disease. Synovectomy is unnecessary

Aims

The sacroiliac joint (SIJ) is the only mechanical connection between the axial skeleton and lower limbs. Following iliosacral resection, there is debate on whether reconstruction of the joint is necessary. There is a paucity of data comparing the outcomes of patients undergoing reconstruction and those who are not formally reconstructed.

Aims

Radiostereometric analysis (RSA) is considered the gold standard for in vivo migration analysis, but CT-based alternatives show comparable results in the shoulder and hip. We have previously validated a CT-based migration analysis method (CTMA) in a knee phantom compared to RSA. In this study, we validated the method in patients undergoing total knee arthroplasty (TKA). Our primary outcome measure was the difference in maximum total point motion (MTPM) between the differing methods.

Aims

The aim of the present study was to analyze the oncological and neurological outcome of patients undergoing interdisciplinary treatment for primary malignant bone and soft-tissue tumours of the spine within the last seven decades, and changes over time.
