Background. Surgical treatment of AIS includes several purposes such as arrest deformity progression through a solid fusion, obtain a permanent correction of the deformity and others. Objectives. To evaluate the improvement of sagittal spinopelvic parameters and clinical outcomes in patients with adolescent idiopathic scoliosis 2 years after corrective surgery. Methods. Radiological and clinical data of 134 consecutive scoliosis patients including 11 boys and 124 girls with the average age of 15.37 years, with AIS Lenke 1, 2, 3, 4, 5 or 6 were included in this retrospective study with 2-year follow-up. Whole spine anterior/posterior and lateral Xray, CT scan and MRI were taken preoperatively, immediately after surgery, at 3 months and 2 years after corrective surgery.
In total hip arthroplasty (THA), cementless cup without screw holes has the putative benefits of maximizing host bone contact and reducing osteolysis by eliminating channels to backside wear particles. However, supplemental trans-acetabular screws cannot be used. 74 hips in 60 patients receiving same model of cementless cup without screw holes (Depuy Duraloc 100 HA cup) from 6/1999 to 3/2003 were prospectively followed up. All patients were allowed to have immediate full weight bearing. Age at THA was 53 ± 13 (range 24–74) years. Osteonecrosis was the leading hip disease (45% of hips). Survivorship was assessed using revision of the cup as the end point.
Cartilage lesions vary in the spectrum from benign enchondromas to highly malignant dedifferentiated chondrosarcomas. From the treatment perspective, enchondromas are observed, Grade 1 chondrosarcomas are curetted like aggressive benign tumors, and rest are resected like other sarcomas. Although biopsy for tissue diagnosis is the gold standard for diagnosis and grade determination in chondrosarcoma, tumor heterogeneity limits the grading in patients following a biopsy. In the absence of definite pre-treatment grading, a surgeon is therefore often in a dilemma when deciding the best treatment option. Radiology has identified aggressive features and aggressiveness scores have been used to try and grade these tumors based on the imaging characteristics but there have been very few published reports with a uniform group and large number of cases to derive a consistent scoring and correlation. The authors asked these study questions :(1) Does Radiology Aggressiveness and its Score correlate with the grade of chondrosarcoma? (2) Can a cut off Radiology Agressiveness Score value be used to guide the clinician and add value to needle biopsy information in offering histological grade dependent management?. A retrospective analysis of patients with long bone extremity intraosseous primary chondrosarcomas were correlated with the final histology grade for the operated patients and
Abstract. Objectives. The principle of osteoporotic vertebral compression fracture (OVCF) is fixing instability, providing anterior support, and decompression. Contraindication for vertebroplasty is anterior or posterior wall fracture. The study objectives was to evaluate the efficacy and safety of vertebroplasty with short segmented PMMA cement augmented pedicle screws for OVCF with posterior/anterior wall fracture patients. Methods. A retrospective study of 24 patients of DGOU type-4 (vertebra plana) OVCF with posterior/anterior wall fracture, were treated by vertebroplasty and short segment PMMA cement augmented pedicle screws fixation.
Abstract. Objectives. To evaluate the safety and efficacy of vertebroplasty with short segmented cement augmented pedicle screws fixation for severe osteoporotic vertebral compression fractures (OVCF) with posterior/anterior wall fractured patients. Methods. A retrospective study of 24 patients of DGOU type-4 (vertebra plana) OVCF with posterior/anterior wall fracture, were treated by vertebroplasty and short segment PMMA cement augmented pedicle screws fixation.
Periacetabular osteotomy (PAO) has been established as an effective technique to treat symptomatic hip dysplasia in young patients. Its role in treating borderline dysplasia and acetabular retroversion is evolving. The aim of this study was to:. Examine the prospectively collected outcomes following a minimally invasive PAO in a large cohort of patients. Compare the outcomes of patients with severe dysplasia, borderline dysplasia and acetabular retroversion. This is a single-surgeon review of patients operated in a high-volume centre with prospectively collected data between 2013 and 2020, and minimal followup of six months. PAO was performed using a minimally invasive modified Smith Peterson approach. 387 patients were operated during the study period and 369 eligible patients included in the final analysis. Radiographic parameters were assessed by two authors (GS and KB) with interrater reliability for 25 patients of 84–95% (IntraClass Coefficient). Patient reported outcome measures (i-HOT 12, NAHS, UCLA and EQ-5D) were collected prospectively. Case note review was also performed to collate complication data and blood transfusion rates.
Aims. To assess the proportion of patients with distal radius fractures (DRFs) who were managed nonoperatively during the COVID-19 pandemic in accordance with the British Orthopaedic Association BOAST COVID-19 guidelines, who would have otherwise been considered for an operative intervention. Methods. We retrospectively reviewed the radiographs and clinical notes of all patients with DRFs managed nonoperatively, following the publication of the BOAST COVID-19 guidelines on the management of urgent trauma between 26 March and 18 May 2020.
Introduction. Open and arthroscopic hip debridement may be used for treatment of femoral acetabular impingement (FAI). There is a paucity of evidence regarding the efficacy of one over the other. Aim. To compare survivorship in terms of further surgical procedure at five years, in patients having undergone either arthroscopic or open hip debridement. Methods. Using our institutional database, we identified all post learning curve arthroscopic and open hip debridement cases with five years of follow up. Patients were matched based on age, gender and Tonnis grade. The primary outcome measure was 5 year survivorship to total hip arthroplasty (THA). Secondary outcome measures included 5 year survivorship to further (non THA) procedures on the joint.
Objectives. The objective of this study was to assess the association between whole body sagittal balance and risk of falls in elderly patients who have sought treatment for back pain. Balanced spinal sagittal alignment is known to be important for the prevention of falls. However, spinal sagittal imbalance can be markedly compensated by the lower extremities, and whole body sagittal balance including the lower extremities should be assessed to evaluate actual imbalances related to falls. Methods. Patients over 70 years old who visited an outpatient clinic for back pain treatment and underwent a standing whole-body radiograph were enrolled. Falls were prospectively assessed for 12 months using a monthly fall diary, and patients were divided into fallers and non-fallers according to the history of falls.
Purpose. The purpose of the present study was to compare functional outcomes of medial unicompartmental knee arthroplasty (UKA) in patients with lateral meniscal lesion (LM (+) group) in the preoperative MRI and those without lateral meniscal pathology (LM (−) group) and to evaluate the effect of lateral meniscus lesion in preoperative MR on functional outcomes after UKA. Methods. The outcomes of 66 knees (LM (+) group) were compared to the outcomes of 54knees(LM (−) group)with a median follow-up of 28 month(range 24–36 months). Clinical outcomes including KS object score, KS pain score, lateral side pain, physical exam for lateral meniscal lesion and squatting ability.
Introduction:. Bicondylar tibial plateau fractures are serious periarticular injuries. We investigated outcomes in injuries managed with Ilizarov external fixators. Methods:. We retrospectively reviewed bicondylar tibial plateau fractures treated with Ilizarov fixators in a major trauma centre from 2008–2012.
The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient’s initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed.Aims
Methods
This was a retrospective study of all AML uncemented femoral prostheses and Duraloc cups in a consecutive series of patients treated between 1990 and 1995. Patients were evaluated clinically using the Merle Score.
Introduction. Internal fixation of pertrochanteric fractures is evolving as newer implants are being developed. Proximal Femoral Nail Antirotation (PFNA) is a recently introduced implant from AO/ASIF designed to compact the cancellous bone and may be particularly useful in unstable and osteoporotic hip fractures. This study is a single and independent centre experience of this implant used in management of acute hip fractures. Methods. 68 patients involving 68 PFNA nailing procedures done over a period of 2 years (2007–09) were included in the study. Average follow-up period of patients was 1 year. AO classification for trochanteric fractures was used to classify all the fractures.
Patients with neurogenic claudication from lumbar canal stenosis non-responsive to non-surgical treatment are usually managed with spinal decompression with or without fusion. Flexion at stenotic segments relieves symptoms by increasing canal cross-sectional area, intervertebral foraminal height. Interspinous spacers work by causing flexion at the treated segement. We used COFLEX¯ [Paradigm Spine] a titanium interspinous spacer along with interlaminar decompression where indicated. To compare the clinical and radiological results of patients undergoing interlaminar decompression with or without use of COFLEX¯. Pre and post-operative assessment and comparison of clinical outcomes of Oswestry disability index(ODI), Visual analog Scale(VAS), Short Form-36(SF-36) and radiological outcomes of disc heights of operated and adjacent levels, intervertebral foraminal heights, sagittal angles of the operated segment. All consecutive patients undergoing spinal decompression at one or more levels from Jan to Dec 2008 were included. Patients with clinically symptomatic back pain for a duration longer than claudication pain were offered interspinous spacer at L4/5 level or above. In first group(n-20), patients were treated with inter-laminar decompression and COFLEX¯ with a standard posterior approach. In second group(n-25) inter-laminar decompression for the involved segment was performed. All patients are on follow-up. Clinical and radiological outcomes were compared at 6 months and 1 year. Statistically significant(p<0.001) improvements in ODI, VAS(back), VAS(leg) and SF-36 in patients in whom COFLEX¯ was used.
Introduction. Radiographic parameters have been shown to have a poor correlation with clinical outcome after open scoliosis procedures. However this has not been previously addressed after endoscopic surgery. The purpose of our study was to examine prospectively the relationship between curve correction and clinical outcome for endoscopic scoliosis surgery. Methods. We studied 50 consecutive patients who underwent endoscopic instrumentation, with a minimum follow-up of two years. All patients were assessed pre-operatively and at 24 months post-operatively.

Background: While several studies in the last years tried to identify clinical limitations of patients suffering from end-stage ankle osteoarthritis (OA), very few attempted to assess foot and ankle function in a more objective biomechanical way, especially using dynamic pedobarography. The aim of the study was therefore to explore plantar pressure distribution characteristics in a large cohort of posttraumatic end-stage ankle OA. Method: 120 patients (female, 54; male, 66; 120 cases) suffering from posttraumatic end-stage ankle OA were included. The clinical examination consisted of assessment of the AOFAS hindfoot score, a pain score, the range of motion (ROM) for ankle dorsiflexion and plantar flexion, and the body mass index (BMI, kg/m2).
Aim: To compare the radiological and functional outcomes of compression type thoracolumbar vertebral fractures treated with cloth-type thoracolumbar orthosis fitted with steel plates and bed rest. Methods: This prospective comparative study was done between July 2004 and January 2007. Twenty three patients (17 male, 6 female) with compression type (Magerl A1) thoracolumbar vertebral fractures were included. No patient had associated neurogical findings or additional injury. Eleven patients were treated with cloth-type thoracolumbar orthosis and 12 patients with only bed rest. Bed rest group cases were instructed to stand up and walk around as possible as they tolerated after pain relief just only in the house under the supervision of it’s relates. All cases were evaluated at last follow-up with SF-36 questionaire, clinical and radiological examination. Results: There was no significant difference between two groups with regard to demographic data.
