Aims. The aim of this study was to determine whether early surgical treatment results in better neurological recovery 12 months after injury than late surgical treatment in patients with acute traumatic spinal cord injury (tSCI). Methods. Patients with tSCI requiring surgical spinal decompression presenting to 17 centres in Europe were recruited. Depending on the timing of decompression, patients were divided into early (≤ 12 hours after injury) and late (> 12 hours and < 14 days after injury) groups. The American Spinal Injury Association neurological (ASIA) examination was performed at baseline (after injury but before decompression) and at 12 months. The primary endpoint was the change in Lower Extremity Motor Score (LEMS) from baseline to 12 months. Results. The final analyses comprised 159 patients in the early and 135 in the late group. Patients in the early group had significantly more severe neurological impairment before surgical treatment. For unadjusted complete-case analysis, mean change in LEMS was 15.6 (95% confidence interval (CI) 12.1 to 19.0) in the early and 11.3 (95% CI 8.3 to 14.3) in the late group, with a mean between-group difference of 4.3 (95% CI -0.3 to 8.8). Using multiply imputed data adjusting for baseline LEMS, baseline ASIA Impairment Scale (AIS), and propensity score, the mean between-group difference in the change in LEMS decreased to 2.2 (95% CI -1.5 to 5.9). Conclusion. Compared to late surgical decompression, early surgical decompression following acute tSCI did not result in statistically significant or clinically meaningful neurological improvements 12 months after injury. These results, however, do not impact the well-established need for acute, non-surgical tSCI management. This is the first study to highlight that a combination of baseline imbalances, ceiling effects, and loss to follow-up rates may yield an overestimate of the effect of early surgical decompression in unadjusted analyses, which underpins the importance of adjusted statistical analyses in acute tSCI research.

Survival of sepsis has been documented worldwide, but little is documented about the long-term health outcomes of multifocal sepsis from acute musculoskeletal infection - the first study of its kind in New Zealand. Children admitted to the Paediatric Intensive Care Unit (PICU) from 1. st. January 2002 to 31. st. December 2017 with a musculoskeletal focus of infection were identified from hospital coding data. Notes review from discharge to present day determined survival and morbidity. Present-day clinical assessment of the musculoskeletal and respiratory systems along with questionnaires on health-related quality of life, mental health and sleep were performed. Seventy patients were studied. Seven children died acutely (five Pasifika and two Māori children) indicating 10% mortality. Long-term survival was favourable with no recorded deaths after discharge. Recurrence/chronic infection occurred in 23%, a mean of 1.1 year after discharge. Growth disturbance occurred in 18%, a mean of 3 years after discharge. The hip joint and proximal femur have the worst complications. Children under 2 years are most at risk of long-term disability. No patients had chronic respiratory illness beyond 90 days. Fifteen children had symptoms of acute neurological impairment, three of whom had permanent brain injury. Twenty-six survivors (41%) were assessed a mean of 8.2 years after discharge. Health-related quality of life scores were on par with normative data. Six patients and eight parents screened positive for moderate to severe post-traumatic stress disorder. Paediatric multifocal musculoskeletal sepsis can result in complex illness with long hospital stay and multi-organ complications. Māori and Pasifika children, those under two and those involving the proximal femur/or hip are most at risk. Other outcomes are favourable with no evidence of chronic lung disease or poor quality of life. A period of rehabilitation for children with identified acquired brain injury should be part of discharge planning

This study aimed to identify long-term physical and psychosocial health outcomes in children with overwhelming musculoskeletal sepsis. Children admitted to the Paediatric Intensive Care Unit (PICU) from 1st January 2002 to 31st December 2017 with a musculoskeletal focus of infection were identified. A medical notes review was completed to determine survival and morbidity. Present-day clinical assessment of the musculoskeletal and respiratory systems along with questionnaires on health-related quality of life, mental health and sleep were performed. 70 patients were identified over 15 years. Seven children died acutely (five Pasifika and two Māori children) indicating 10% mortality. Recurrence/chronic infection affected 23%. Growth disturbance affected 18%. The hip joint and proximal femur suffered the worst long-term complications. Children under 2 years most at risk of long-term disability. No patients had chronic respiratory illness beyond 90 days. Fifteen children had symptoms of acute neurological impairment, three of whom had permanent acquired brain injury. Twenty-six survivors (41%) were assessed a mean of 8.2 years (SD 4.5, range 2– 18 years) after discharge. Health-related quality of life scores were on par with normative data. All patients who underwent pulmonary function tests had normal results. Six patients and eight parents screened positive for moderate to severe post-traumatic stress disorder. Paediatric multifocal musculoskeletal sepsis can result in complex illness with multi-organ complications for some children. Māori and Pasifika children are most at risk. Children under 2 years and those with proximal femur and/or hip involvement are most likely to have chronic musculoskeletal sequelae and permanent disability. Other outcomes are favourable with no evidence of chronic lung disease or mean reduced quality of life. A period of rehabilitation for children with identified acquired brain injury should be part of discharge planning

Aim. Spinal implant-associated infections (SIAI) require combined surgical and antimicrobial treatment and prolonged hospital stay. We evaluated the clinical, laboratory, microbiological and radiological characteristics and treatment approaches in patients with SIAI. Method. Consecutive adult patients with SIAI treated between 2015 and 2017 were prosepctively included. SIAI was defined by: (i) significant microbial growth from intraoperative tissue or sonication fluid, (ii) intraoperative purulence, secondary wound dehiscence or implant on view, (iii) radiographic evidence of infection and fever (>38°C) without other recognized cause, increasing back pain or neurologic impairment, (iv) peri-implant tissue inflammation in histopathology. Results. A total of 60 patients were included, median age was 66 years (range, 28–91 years), 29 (48%) were males. The most common reason for spinal stabilization was spinal canal stenosis in 20 patients (33%) followed by vertebral degenerative disease in 14 (23%). 31 patients (52%) had one or more previous spine surgeries (range, 1–4 interventions). The anatomic site of spinal instrumentation was lumbar/sacral in 26 (43%), cervical in 23 patients (38%), thoracic in 11 (18%). The median number of fused segments was 5 (range, 1–14). Clinical manifestations included wound healing disturbance in 41 patients (68%), increasing back pain in 15 (25%), neurologic impairment in 12 patients (20%) and fever in 14 (23%). Serum CRP was abnormal (>10mg/l) in 46/59 patients (78%). Most (n=54) infections were postsurgical, 5 were hematogenous and 1 was contiguous. Imaging showed epidural, intraspinal or paravertebral abscess in 21/42 patients (50%), implant failure in 9 (21%) and implant loosening in 3 cases (7%). Monomicrobial infection was observed in 41 (68%), polymicrobial in 16 (27%) patients and culture-negative infection in 3 episodes (5%). Predominant causative pathogens were S. aureus (n=19), coagulase-negative staphylococci (n=18) and gram-negative rods (n=16). Surgery was performed in all patients including debridement and implant retention in 39 patients (65%), partial implant exchange in 10 (17%) and complete exchange in 11 (18%). Antimicrobial treatment included biofilm-active substances in 52 patients (87%). The median duration of antimicrobial therapy was 11,7 weeks (range, 6–12 weeks). 14 patients (23%) recieved suppressive therapy for a median duration of 9 months (range 3–12 months). Conclusions. Most SIAI were seen in lumbar/sacral segments and wound healing disturbance and increasing back pain were the most common manifestations. In 95% the causative pathogen was isolated, predominantly staphylococci. In half of the episodes, abscesses were present. All patients underwent surgery and biofilm-active antibiotics were administered in 87%

Introduction: Forearm fractures are the most common long bone fracture in the paediatric population. Associated neurological injury is a well recognized complication of these injuries yet is generally considered to beuncommon. This study sought to evaluate the incidence of neurological impairment in children referred for manipulation by the orthopaedics team in this tertiary referral hospital. Materials & Methods: A retrospective chart analysis was performed of the first 100 children to be referred for orthopaedic assessment. This represented 43% of the total number of children presenting to the emergency department in this time period. Inclusion criteria involved a fracture of any segment of the radius and/or ulna on radiological examination. Exclusion criteria included concomitant ipsilateral upper limb fracture, and compartment syndrome. Results: A total of 96 cases met the inclusion criteria. The cohort had a mean age of 8.04. Males were more likely to be injured as was the left forearm. The distal metaphysis was the segment most likely to be fractured and compound injuries were uncommon. The incidence of associated neurological impairment was 15.6%. The median nerve was most commonly injured, comprising 60% of nerve injuries. Distal physeal fractures were the most common fracture pattern to be associated with neurological impairment, with a rate of 37%. Conclusions: Forearm fractures requiring manipulation in the paediatric population are commonly associated with nerve injuries, with distal physeal fractures having a particularly strong correlation. Clinicians require a high index of suspicion for nerve injury when evaluating forearm fractures to avoid underdiagnosis. Failure to recognize neurological injury at the time of initial assessment has the potential to delay time to reduction due to the injury being misclassified as non-urgent. This delay has the potential to cause a prolonged or failed recovery of nerve function

The spine is a common site of metastasis. Complications include pathologic fracture, spinal cord compression, and neurological deficits. Vertebroplasty (VP) and Balloon Kyphoplasty (KP) are minimally invasive stabilization procedures used as a palliative treatment to improve mechanical stability, quality of life, and reduce pain. Photodynamic therapy (PDT) is a tumour-ablative modality that may complement mechanical stability afforded by VP/KP. This first-in-human study evaluates PDT safety when applied in conjunction with VP/KP. This dose escalation trial involved one light only control group and four light-drug doses (50,100,150,200J;n=6) delivered at 150mW from a 690nm diode laser by 800-micron optical fibers prior to KP/VP. Patients eligible for VP/KP in treating pathologic fracture or at-risk lesions at a single level were recruited. Exclusion criteria included spinal canal compromise or neurologic impairment. PDT is a two-step binary therapy of systemic drug followed by intravertebral light activation. Light was applied via bone trochar prior to cementation. This study used a benzoporphyrin derivative monoacid (BPD-MA), Verteporfin (VisudyneTm), as the photosensitizer drug in the therapy. Drug/light safety, neurologic safety, generic (SF-36), and disease-specific outcomes (VAS, EORTC-QLQ-BM22, EORTC-QLQ-C15-PAL) were recorded through six weeks. Phototoxicity and the side effects of the BPD-MA were also examined following PDT use. Thirty (10 male, 20 female) patients were treated (13 KP, 17 VP). The average age was 61 and significantly different between genders (Male 70yrs vs. Female 57yrs: p 0.05), and tumour status (lytic vs. mixed blastic/lytic: p>0.05). In most cases, fluence rates were similar throughout PDT treatment time, indicating a relatively stable treatment. Twelve (40%) of patients experienced complications during the study, none of which were attributed to PDT therapy. This included two kyphoplasty failures due to progression of disease, one case of shingles, one ankle fracture, one prominent suture, one case of constipation due to a lung lesion, one case of fatigue, and five patients experienced pain that was surgically related or preceded therapy. Vertebral PDT appears safe from pharmaceutical and neurologic perspectives. KP/VP failure rate is broadly in line with reported values and PDT did not compromise efficacy. The 50J group demonstrated an improved response. Ongoing study determining safe dose range and subsequent efficacy studies are necessary

Background. There is minimal published data regarding the long-term functional outcome in pyogenic spinal infection. Previous studies have used heterogeneous, unreliable and non-validated measure instruments, or neurological outcome alone, yielding data that is difficult to interpret. We aim to assess long-term adverse outcome using standardised measures, Oswestry disability index (ODI) and MOS short form-36 (SF-36). Methods. All cases of pyogenic spinal infection presenting to a single institution managed operatively and non-operatively from 1994-2004 were retrospectively identified. Follow-up was by clinical review and standardised questionnaires. Inclusion in each case was on the basis of consistent clinical, imaging and microbiology criteria. Results. Twenty-nine cases of pyogenic spinal infection were identified. Twenty-eight percent were managed operatively and 72% with antibiotic therapy alone. Nineteen patients (66%) had an adverse outcome at a median follow-up of 61 months, despite only 5 patients (17%) having persistent neurological deficit. A significant difference in SF-36 PF (physical function) scores was observed between patients with adverse outcome and patients who recovered (p=0.003). SF-36 scores of all patients, regardless of management or outcome, failed to reach those of a normative population. A strong correlation was observed between ODI and SF-36 PF scores (rho=0.61, p<0.05). Seventeen percent (n=5) of admissions resulted in acute sepsis-related death. Subgroup analysis revealed delay in diagnosis of spinal infection (p=0.025) and neurological impairment at diagnosis (p<0.001) to be significant predictors of neurological deficit at follow-up. Previous spinal surgery was associated with adverse outcome in patients requiring readmission within 1 year of hospital discharge following first spinal infection (p=0.018). No independent predictors of adverse outcome, persistent neurological impairment, readmission within 1 year or acute death were identified by logistical regression analysis. Conclusions. High rates of adverse outcome detected using SF-36 and ODI suggest under-reporting of poor outcome when ASIA score alone is used to qualify outcome

Several methods of surgical treatment for pyogenic spondylitis have been reported including anterior approach, staged and simultaneous anterior decompression and posterior stabilisation. The use of anterior implants in the presence of infection presents still a challenge for spine surgeons. Retrospective analysis of the clinical and radiological outcome of patients suffering from pyogenic spondylitis of the cervical and lumbar spine necessitating surgical treatment for intractable pain, instability and neurologic impairment. Seventeen patients with spondylitis associated or not with paravertebral abscess were treated by one stage surgery (first: anterior decompression and placement of titanium mesh cage, filled with autologous iliac bone graft; second: posterior transpedicular instrumentation and fusion). The age of the patients was 54 ±15 years. Most of the patients had systematic problems such as lung tuberculosis, hepatic cirrhosis, diabetes mellitus or chronic renal failure. Patients were evaluated before and after surgery in terms of pain and neurological level, sagittal spinal balance and radiological fusion. All 17 patients were followed for 45 months. Average duration of both surgeries was 4.5 hours. The VAS score improved from 7 (preoperatively) to 2 (postoperatively). The correction of the segmental kyphotic deformity was 6o, without loss of correction or cage migration or instrumentation failure. All patients with incomplete neurologic impairment improved postoperatively. There was neither migration of mesh cage nor posterior instrumentation failure at the follow up observation. There was an approach-related abdominal hernia. This clinical study showed that patients with cervical and thoracolumbar osteomyelitis necessitating surgery for certain indications can successfully undergo instrumented combined, one-stage, same-day surgery. The presence of the mesh cage anteriorly at the site of infection had not negative but beneficial influence on the course of infection healing, and it additionally stabilised the affected segment, maintaining sufficient sagittal profile

Purpose: The purpose of this study is to analyze the anatomo-radiological results, the clinical results, and complications of minimally displaced fractures of the proximal humerus, treated by immediate, ambulatory self-passive mobilization, followed by a strengthening and propioceptive training program. Materials and Methods: 12 patients, 7 females and 5 males, mean age 56.91 (SD: 15.76) were reviewed retrospectively at a mean of 28.33 months follow-up. All the patients were mobilized the day after the first visit, i.e. the day after the fracture in 7 patients (58.3%), up to 7 days after the fracture in 4 patients and 3 weeks after the fracture in one late referral. Over an average period of 5.8 months, an average 45.41 (SD: 20.83) sessions of rehabilitation, with a therapist, for each patient, were recorded. The patients were recommended to perform four sessions of self rehabilitation a day. Clinical evaluation included a questionnaire covering subjective evaluation, Activities of Daily Living (ADL) by means of the ASA index and the Constant’s score, and type and duration of rehabilitation. The radiological evaluation included review of the X-rays, from the initial traumatic event to the last follow up X-ray. An AP view with three rotations, outlet view and axillary view were performed for each patient. The fracture type, displacement, interval for union, glenohumeral osteoarthritis (according to the Samilson classification), type of acromion and osteoporosis, were recorded. Special attention was paid in detecting joint stiffness, algodystrophy, neurological impairment, malunion, further displacement, signs of avascular necrosis and post-traumatic osteoarthritis. Results: The mean non adjusted Constant’s score at last follow up was 88.33 over 100 (SD: 11.45) an average of 96.01% compared to the contralateral side. 83% of patients were pain free, and 17% reported mild pain. Active motion was very satisfactory averaging 96.23% in forward flexion, 89.86% in external rotation with the hand at the side, and 90.22% in external rotation at 90° abduction, and a difference of 1.46 vertebral levels in active internal rotation, as compared to the contralateral shoulder. Passive motion was also analyzed in the same way. Power of the affected shoulder in forward elevation was on average 90.19% of the contralateral side. Impingement was tested by the Neer, Hawkins and Yocum signs: 4 patients (33.3%) reported at least one positive sign of impingement. The Jobe and Palm up tests were negative in 100% of patients. 11 patients were very satisfied and 1 patient satisfied. Joint stiffness developed in one case (8.3%), with 100° of forward elevation, 50° external rotation with the hand at the side, 50° external rotation at 90° abduction. No algodystrophy, no neurological impairment, no further displacement, no signs of avascular necrosis, no post-traumatic progression of osteoarthritis, were observed in any case. Union was achieved in all the 12 patients, in 2 cases with some degree of angulation. Conclusions: Very good functional and radiological results were obtained with immediate passive mobilization of minimally displaced fractures of the proximal humerus. It is a safe method as all the fractures united and the rate of complication was very low especially without joint stiffness or RSD and with very good patient satisfaction

We report the clinical features and treatment on a rare case of Candida albicans lumbar spondylodiscitis in a non-immunocompromised patient. Its indolent course leads to delayed suspicion and diagnosis. As soon as fungal infection is suspected investigations with MRI and biopsy should be performed followed by medical therapy. Retrospective data analysis. A 58-year-old male underwent surgery for adenocarcinoma of the ampula of Vater treatment. Subsequently, the patient had a prolonged intensive care unit stay due to major complications, during his stay he developed a septicemia with Candida albicans isolated in the blood work. He received antifungal therapy anidulofungin, later changed to fluconazole during 2 weeks. Repeated blood work were negative and no vegetations on echocardiogram were seen. He was discharged from the ICU to a surgery floor. During the surgical unit stay he presented with lower back pain radiating to the lower limbs. Findings on neurological examination were normal, radiographs of the lumbar spine revealed L5-S1 antero listhesis. He was treated with oral non-steroidal anti-inflammatory drugs and an lumbar MRI and orthopaedic consultation was agended. One month later, after minor trauma he developed myelopathic symptoms with weakness of both lower limbs and severe back pain. Plain radiograph showed anterolistesis worsening. Magnetic resonance imaging showed endplate erosion at L5/S1. There also was evidence of paraspinal collection with epidural compression of the dural sac. The patient was treated surgicaly with debridement and posterior instrumented fusion from L4 to S1. Disk and end-plate material collected confirmed Candidal infection. The patient recovered most of his neurological deficit immediately after surgery. He was subsequently treated during 2 weeks with liposomal amphotericin B, later changed to fluconazole 400mg per os per day. He maintained antifungal therapy during 15 months. He remains asymptomatic with no recurrence of infection clinically or radiologically after surgery. Fungal spondylodiscitis is rare. Sub-acute or chronic low back pain in either immunocompromised or non-immunocompromised patients cronically ill and malnourished (parental nutrition) there must be high index of suspicion for fungal infections. Therefore we recommend screening for Candida osteomyelistis in these cases. Without treatment, involvement of vertebral bodies can lead to compression fractures, deformity of the spine and neurological impairment

Purpose of the study. To review the primary bone tumours of the spine treated at our unit. Description of methods. Retrospective review of folders and x-rays of all the patients with primary bone tumours of the spine treated at our unit between 2005 and 2012. All haematological tumours were excluded. Summary of results. We treated 15 cases during this period. The median age at presentation was 36 years (8–65). There was a significant delay from onset of symptoms to diagnosis in most cases (median 7 months). Histological diagnoses included:. -Benign tumours.  Active. Hemangioma. 3. Osteoid osteoma. 1. Eosinophilic granuloma. 1.  Aggressive. Osteoblastoma. 1. Giant cell tumours. 2. Aneurysmal bone cysts. 4. -Malignant tumours.  Osteosarcomas. 2.  Leiomyosarcoma of bone. 1. A variety of definitive surgical methods were utilised. Seven patients had a debulking or intralesional resection of the tumour. Eight patients had an attempted marginal excision. This was achieved through anterior surgery only in 1 case, posterior only surgery in 6 cases and combination anterior and posterior surgery in 8 cases. The anterior and posterior surgery was performed in a single sitting in 5 cases and in a staged fashion in 3 cases. Adjuvant radiotherapy and chemotherapy were used where indicated. Three cases presented with significant neurological impairment. Of these 2 made a significant recovery. There were no cases of neurological deterioration following surgery. All 3 patients with malignant tumours died in the follow up period. We had 1 case of hardware failure due to chronic sepsis. Conclusion. Primary bone tumours of the spine are associated with a significant delay in diagnosis. Surgical treatment options and adjuvant therapy should be tailor made for each case depending on the diagnosis. Acceptable results with minimal complications can be achieved with this approach

Background. Rotatory subluxation of the atlantoaxial joint has been thoroughly documented in children. However, pure traumatic atlantoaxial rotatory subluxation (TAARS) is a rare injury in adults with only a few cases reported in the English literature. Aim. To report two cases of TAARS in adults. Methods. A case note, clinical and radiological review. Results. Both patients were female. There was a history of a motor vehicle collision in both cases. There was no neurological impairment at presentation in either case. The injury in both cases was identified by plain X-ray and confirmed by CT scan. Both were managed by conservative treatment, initially with halo traction, followed by immobilisation in a rigid collar. Final clinical reviews occurred at 7 years and 2.5 years following injury. Neither patient had signs of C1-C2 instability or impaired neurology. Both patients, however, suffered headaches and occipital neuralgia, with stiffness and reduction in cervical spine movement. Conclusion. Traumatic rotatory subluxation in adults is a rare injury. It can pose a diagnostic challenge and CT scanning is mandatory for a correct evaluation of the C1-2 complex. Reduction and stability can be achieved through conservative treatment. However, it is evident from this short series that even early diagnosis and prompt reduction may not necessarily result in a good long term outcome in adult patients with TAARS

In this study we try to evaluate the results of intramedullary nailing in the treatment of fractures of diaphysis of humerus. During the time period of 2002 to 2006 46 patients were admitted in our clinic with fracture of the diaphysis of the humerus and 23 patients were treated surgically with intramedullary nailing. 14 patients were directly submitted to intramedullary nailing, 6 patients after unsuccessful conservative treatment and 3 patients due to nonunion after internal fixation. Average age was 51 years old. In 5 patients open reduction was applied while bone grafts were not used in any case. In all cases bone healing was obtained within 6 to 20 weeks (average 11 weeks). Final functional outcome was evaluated with Constant Score and according to it 10 patients demonstrated excellent score (> 75), 7 satisfactory (50–75) and 6 poor(< 50). Postoperative evaluation was based on clinical findings such as pain, range of motion and rehabilitation. As far as complications are concerned 2 cases with severe stiffness of the shoulder were observed and 1 case with malunion. There were no cases with non-union, sterile necrosis or neurological impairment. Intramedullary nailing shows significant advantages such as limited damage to soft tissues, satisfactory retention of osteoporotic fractures, immobility of complex fractures and allows immediate postoperative mobilization

This poster describes the separation of a pair of conjoined twins, aged 3 months. They were joined at the pelvis, shared a common hindgut and each had bladder exstrophy. The operation to separate them, done over a weekend, involved paired teams of anaesthetists, Paediatric Surgeons and Paediatric Urologists and one Orthopaedic Surgeon. The surgeons mobilised and divided the hindgut, giving one twin the distal half and the other the caecum and proximal colon. Two Urologists reconstructed the bladder exstrophies. The orthopaedic contribution was bilateral oblique pelvic osteotomy to allow midline closure, along with extensive hip releases to deal with severe flexion and abduction contractures. Both twins survived and are thriving. They have little neurological impairment in the lower limbs and therefore have great potential to walk

Twenty-one patients with spinal brucellosis were reviewed. The disease is difficult to diagnose, and is often confused with spinal tuberculosis. Our study showed that it was best diagnosed by serology and bacterial culture; radiography and scanning were less helpful in the early stages. After only six weeks' antibiotic treatment, there was a 55% clinical and serological reactivation rate: better results were achieved after at least three months of treatment. The adequacy of treatment was best monitored with repeated agglutination titres, and the duration of treatment proved to be more important than the antibiotic agent itself. Surgical intervention was reserved for biopsy, severe neurological impairment, or for spinal stabilisation

We reviewed retrospectively the role of monitoring of somatosensory spinal evoked potentials (SSEP) in 99 patients with neuromuscular scoliosis who had had operative correction with Luque-Galveston rods and sublaminar wiring. Our findings showed that SSEP monitoring was useful and that a 50% decrease in the amplitude of the trace optimised both sensitivity and specificity. The detection of true-positive results was higher than in cases of idiopathic scoliosis, but the method was less sensitive and specific and there were more false-negative results. In contrast with the findings in idiopathic scoliosis, recovery of the trace was associated with a 50% to 60% risk of neurological impairment. Only one permanent injury occurred during the use of this technique, and any temporary impairment resolved within two months

We performed a neurological and radiological study of the wrists of 58 patients with Hansen’s disease and 60 age-matched healthy control subjects. Significant differences (p < 0.01) were found between the groups in the carpal glenoid sector, the radial physeal widening index, the carpal ulnar distance, the carpal index and in distal radio-ulnar discrepancy. Comparison of the results in three subgroups of leprous patients with sensory impairment (group A-1), motor deficit (A-2) and no neurological impairment (A-3), showed significant differences (p < 0.01) between group A-1 and the other two. This suggests that in these patients the changes in the carpus and radiocarpal joint may be caused by neuropathic arthropathy of the wrist. Our findings are of particular interest since there are few reports of neuropathic arthropathy in non-weight-bearing joints

Among elderly Caucasians, fractures of the femoral neck are a common cause of disability. Intertrochanteric and intra-capsular fractures occur equally often, and both are about three times more common in women than in men. Risk factors include neurological impairment, malnutrition, impaired vision, malignancy and decreased activity. We found that in black South Africans femoral neck fractures occur equally often in men and in women. Intracapsular fractures are comparatively rare, occurring in one of every eight female patients and one of every 3.5 male patients. Further, we found that in both black men and black women the femoral neck was consistently and significantly shorter than in whites. These results suggest that a short femoral neck may offer protection not only against intracapsular fracture, but also possibly against fracture of the femoral neck in general. In addition, greater cortical thickness in black people probably offers further protection

Introduction:. Trauma is endemic in South Africa. The upper thoracic spine is extremely difficult to image and assess clearly with frontline x-rays resulting in up to 22% of proximal fractures being missed. Aim:. To review a series of patients with proximal thoracic fractures. Methods:. Thirty-three patients with proximal thoracic fractures in the T1–T4 area managed in a spinal unit were identified. A retrospective review of medical records and radiology was undertaken. Demographic data, mechanism of injury, diagnostic modalities, level and type of fracture, neurological status, associated injuries, hospital stay, management, complications and outcome was recorded. Results:. There were 21 males and 12 females, with a median age of 31.8 years. Aetiology was 21 MVA passengers, 8 drivers, 1 pedestrian, 1 assault, 1 bicycle and 1 hanglider accident. Delay in diagnosis was 1 day in 8, 2–5 days in 2 and greater than 2 weeks in 5. The fractures were A1 in 7, A3 in 14, B1 in 7, C1 in 2 and C2 in 2. Twenty three patients had neurological compromise, 13 being complete. Twenty-three had associated chest and head injuries. Hospital stay was a mean of 27 days (maximum 246) and ICU stay median 14 (maximum 115) days. Twenty-six patients underwent surgery, posterior instrumented fusion being the commonest procedure. Although the surgery did not change the median kyphosis (25° preop to 20°at 1 year and 21°at 2 years), the most kyphotic patients were improved (55°to 45°). Conclusion:. A high index of suspicion for proximal thoracic fractures needs to be maintained in high energy injuries, especially MVA passengers, where there is chest injury. Prompt exclusion by appropriate special investigations is mandatory. Once recognized, they can be adequately managed with posterior instrumented fusion, although these patients are resource intensive due to the associated neurological impairment and chest injuries

We have reviewed 32 patients with rheumatoid disease of the cervical spine who underwent a total of 40 operations aimed at correcting instability and improving any associated neurovascular deficit. Apart from four patients with intractable pain, the main indication for surgery was progressive neurological impairment. Of the 32 primary operations, 19 (60%) were successful; the remainder failed to achieve their objective and there were two deaths in the immediate postoperative period. Of eight secondary operations performed for recurrence of symptoms or failure to relieve cervical myelopathy, only four were successful. Of nine operations for bony decompression to relieve cord compression from irreducible subluxation, only four were successful. The overall results show a success rate of 57% and a failure rate of 35% with early operative mortality in 8%. Indications for operation are discussed and earlier diagnosis is considered to be the key to improved results
