Aims

The worldwide COVID-19 pandemic is directly impacting the field of orthopaedic surgery and traumatology with postponed operations, changed status of planned elective surgeries and acute emergencies in patients with unknown infection status. To this point, Germany's COVID-19 infection numbers and death rate have been lower than those of many other nations.

We have measured the increase in height and width of the vertebral bodies and expressed them as percentages of the total growth in children aged 10 to 17 years. The first group, 10 boys and 10 girls, each had a single thoracic adolescent idiopathic scoliosis while the second group, 10 girls, each had a single lumbar adolescent idiopathic scoliosis. No significant differences were found between the growth increments and spinal dimensions of the vertebral bodies involved in the scoliotic curve and those vertebrae outside the curve in the same patient. The vertebrae were more slender in girls than in boys

Acute myelopathy is a rare complication of Scheuermann's disease. Three patients are reported where spinal cord compression occurred at the apex of a kyphos. All were male, aged 14, 18 and 20 years, and each had a profound neurological defect associated with a short, sharp kyphos in the low thoracic region. Each patient underwent anterior decompression and all made an almost full recovery. It is deduced that factors which may influence the onset of cord compression include the angle of kyphosis, the number of segments involved, the rate of change of the angle, local anatomical variations, trauma, and possible secondary impairment of the vasculature of the cord

1. Twenty-eight patients with pyogenic infection of the spine are reported. 2. Diagnosis was by clinical, radiological and bacteriological means. Investigations of the spinal lesions by needle aspiration or open operation was needed in four patients. 3. Treatment consisted primarily of antibiotics and rest. 4. Twenty-five patients were fit and well after follow-up of one to fifteen years. Three deaths occurred, but only one was directly connected with the infection ; urinary infection with paraplegia and haemophilia were the cause in two others. 5. The relatively benign course is stressed, as are some of the diagnostic pitfalls in the early stages, particularly with thoracic lesions

We have studied 34 consecutive patients receiving Cotrel- Dubousset instrumentation for a single and flexible thoracic scoliotic curve, evaluating the rib hump deformity from a single CT scan through the apical vertebra of the curve. Using two measures of rotation we found a mean improvement of 25% in the rotation of the vertebra after operation. Any, usually minor, deterioration occurred in the first six months postoperatively, and there was no significant further deterioration in 19 patients assessed over two years after surgery. Cotrel-Dubousset instrumentation can produce a significant correction of vertebral rotation and of the associated rib hump deformity

Aims

The current pandemic caused by COVID-19 is the biggest challenge for national health systems for a century. While most medical resources are allocated to treat COVID-19 patients, several non-COVID-19 medical emergencies still need to be treated, including vertebral fractures and spinal cord compression. The aim of this paper is to report the early experience and an organizational protocol for emergency spinal surgery currently being used in a large metropolitan area by an integrated team of orthopaedic surgeons and neurosurgeons.

Twenty-eight patients with adolescent idiopathic scoliosis treated by anterior spinal fusion with Dwyer instrumentation were reviewed. The average length of follow-up was 6.9 years. This technique produced better correction of lateral curvature and rotation than Harrington instrumentation, particularly in the thoracolumbar and lumbar region. The length of spine requiring fusion was also shorter. There is, however, a tendency for Dwyer instrumentation to lead to kyphosis. Morbidity was significant and included one case of paraplegia, four cases of deep infection and one case of instrument failure. All of these complications, except one case of deep infection, occurred in patients with curves with an apex above the seventh thoracic vertebra

A series of 98 patients with juvenile idiopathic scoliosis have been analysed. This showed that between the ages of four and six there was a higher incidence in boys whereas between seven and nine years of age, the proportion of girls was higher. Regardless of sex and age the majority of the curves were convex to the right and the single thoracic curve was the commonest pattern. Spontaneous resolution occurred in seven patients: in four the curves resolved within two years; in the three others the curves resolved in three, four and five years respectively. Forty-four per cent of all patients were managed conservatively and in 56 per cent spinal fusion was carried out

Early decompression in Pott's paraplegia gives encouraging results. It produces speedy recovery from paraplegia and ensures rapid healing of the lesion. Lateral extrapleural decompression without fusion for lesions of thoracic vertebrae is safe and satisfactory. It gives adequate exposure of the anterior and posterior parts of the vertebral bodies and of the theca, without endangering the stability of the spine. Age, sex and site of the lesion have no influence on the prognosis, whereas paraplegia of longer duration, paraplegia in flexion, and paraplegia presenting as a spinal cord tumour carry a bad prognosis. In early lesions there is reconstitution of vertebral bodies whereas in advanced lesions there is consolidation or bony fusion

Aims

COVID-19 has changed the practice of orthopaedics across the globe. The medical workforce has dealt with this outbreak with varying strategies and adaptations, which are relevant to its field and to the region. As one of the ‘hotspots’ in the UK , the surgical branch of trauma and orthopaedics need strategies to adapt to the ever-changing landscape of COVID-19.

1. A case of solitary plasmocytoma of the thoracic part of the spine, verified by necropsy, is described. 2. A brief review is given of eighteen acceptable cases of solitary plasmocytoma of bone. 3. Of the eighteen patients, fifteen were men; the five spinal tumours were all in men. 4. Diagnosis requires: a) biopsy identification of plasmocytoma; b) exclusion of the possibility of generalised myelomatosis by complete radiography of the skeleton, repeated if necessary at intervals during the ensuing two or three years or longer. 5. A tumour of brief duration, proved to be solitary by careful necropsy, cannot be placed with certainty in the group of truly solitary plasmocytomas; it might have been a precocious first lesion of myelomatosis

Virtual encounters have experienced an exponential rise amid the current COVID-19 crisis. This abrupt change, seen in response to unprecedented medical and environmental challenges, has been forced upon the orthopaedic community. However, such changes to adopting virtual care and technology were already in the evolution forecast, albeit in an unpredictable timetable impeded by regulatory and financial barriers. This adoption is not meant to replace, but rather augment established, traditional models of care while ensuring patient/provider safety, especially during the pandemic. While our department, like those of other institutions, has performed virtual care for several years, it represented a small fraction of daily care. The pandemic required an accelerated and comprehensive approach to the new reality. Contemporary literature has already shown equivalent safety and patient satisfaction, as well as superior efficiency and reduced expenses with musculoskeletal virtual care (MSKVC) versus traditional models. Nevertheless, current literature detailing operational models of MSKVC is scarce. The current review describes our pre-pandemic MSKVC model and the shift to a MSKVC pandemic workflow that enumerates the conceptual workflow organization (patient triage, from timely care provision based on symptom acuity/severity to a continuum that includes future follow-up). Furthermore, specific setup requirements (both resource/personnel requirements such as hardware, software, and network connectivity requirements, and patient/provider characteristics respectively), and professional expectations are outlined. MSKVC has already become a pivotal element of musculoskeletal care, due to COVID-19, and these changes are confidently here to stay. Readiness to adapt and evolve will be required of individual musculoskeletal clinical teams as well as organizations, as established paradigms evolve.

Nineteen patients with thoracic or thoracolumbar spinal tuberculosis and neurological deficits were treated by anterior debridement, decompression and vascularised rib grafting, followed, either during the same procedure or 14 days later, by multilevel posterior osteotomies, instrumentation and fusion. Surgery was performed under cover of four-drug antituberculosis chemotherapy, given for 12 months. The average pre-operative kyphotic angulation of 56 degrees was reduced to 27 degrees postoperatively and 30 degrees at the latest follow-up (3 degrees loss of correction). Radiological fusion between the vascularised rib graft and the vertebrae was seen after an average of 3.3 months. Eighteen patients (95%) had normal neurological function at 14 months, and the other could walk with the aid of crutches

Progressive structural scoliosis in growing rabbits has been produced. Tethering the thoracic spine into the form of an asymmetric lordosis produces a slowly progressive structural scoliosis by purely mechanical means. The addition of a contralateral release of the paraspinal muscles leads to a very progressive deformity with early cardiorespiratory failure. This release, however, was performed with an electric soldering iron and subsequent study showed that in those animals with severe progressive deformity there was localised spinal cord damage. We suggest that it is this neural damage and not the muscle release which leads to rapid progression. The clinical implications are important in that neurological dysfunction seems to render the spinal column less able to resist mechanical buckling and may be the crucial factor differentiating severely progressive from more benign curves

Between 1969 and 1989, we performed posterior segmental instrumentation on 38 patients with thoracic Scheuermann's kyphosis. We used a dynamic system without sublaminar fixation, and a kyphosis of 50 degrees was the main indication for surgery. The mean initial angle was 68 degrees (50 to 100) and the mean final kyphosis was 43 degrees at five-year follow-up, with a mean final loss after surgery of 3.7 degrees. Reconstruction of the vertebral bodies, vertebral wedging and the anterior-body height ratio were observed even in skeletally mature patients. There were no medical complications. There were three cases of loss of correction by more than 10 degrees and one of rod fracture with pseudarthrosis. The role of non-operative treatment is evaluated and early surgical treatment is advocated

We reviewed 47 patients with neurofibromatosis and dystrophic spinal deformities; 32 of these patients had been untreated for an average of 3.6 years and in them the natural history was studied. The commonest pattern of deformity at the time of presentation was a short angular thoracic scoliosis, but with progression the angle of kyphosis also increased. Deterioration during childhood was usual but its rate was variable. Severe dystrophic changes in the apical vertebrae and in particular anterior scalloping have a poor prognosis for deterioration. The dystrophic spinal deformity of neurofibromatosis requires early surgical stabilisation which should be by combined anterior and posterior fusion if there is an abnormal angle of kyphosis or severely dystrophic apical vertebrae. Some carefully selected patients can be treated by posterior fusion and instrumentation alone

Thirty-four patients with adolescent idiopathic scoliosis were assessed by radiography and the integrated shape imaging system (ISIS) both before and after spinal surgery. Twenty-seven patients underwent Harrington instrumentation, after which lateral indices of curvature were significantly improved, but changes in the transverse plane were less pronounced. Sublaminar wiring was carried out in two patients whose thoracic lordosis was corrected by the surgery. Five patients whose severe deformity had persisted after previous spinal surgery underwent costoplasty, which resulted in a significant improvement in back shape measurements. We conclude that the cosmetic deformity of the back in scoliosis is only partially corrected by operations on the spine itself, whilst costoplasty addresses the problem directly, and improves the surface shape

Between 1955 and 1989 we treated 24 patients (17 women and seven men) with giant-cell tumours of the spine at the Mayo Clinic. Their mean age was 30 years and the mean follow-up time was 12.4 years. Pain was the presenting symptom in all and half had a neurological deficit. The cervical, thoracic, and lumbar spines were equally involved. The tumours recurred in five of the 14 patients treated by one-stage surgery and in five of the ten treated by two-stage surgery. Seven patients received adjuvant radiotherapy, one for the primary lesion and six for recurrent lesions. Surgical management was by curettage or en bloc excision depending on the location and the extent of the tumour. Because of the risk of sarcomatous transformation, radiation therapy should be reserved for patients with incomplete excision or for those with local recurrence
