Aims

To compare time dependent functional improvement for patients with medial, respectively lateral knee osteoarthritis (OA) after treatment with opening wedge osteotomy relieving the pressure on the osteoarthritic part of the knee.

Aims

The hypothesis of this study was that bone peg fixation in the treatment of osteochondral lesions of the talus would show satisfactory clinical and radiological results, without complications.

Aims

Intravenous dexamethasone has been shown to reduce immediate postoperative pain after total hip arthroplasty (THA), though the effects are short-lived. We aimed to assess whether two equivalent perioperative split doses were more effective than a single preoperative dose.

We examined the differences in post-operative functional disability and patient satisfaction between 56 patients who underwent a lumbar fusion at three or more levels for degenerative disease (group I) and 69 patients, matched by age and gender, who had undergone a one or two level fusion (group II). Their mean age was 66 years (49 to 84) and the mean follow-up was 43 months (24 to 65). The mean pre-operative Oswestry Disability Index (ODI) and visual analogue scale (VAS) for back and leg pain, and the mean post-operative VAS were similar in both groups (p >  0.05), but post-operatively the improvement in ODI was significantly less in group I (40.6%) than in group II (49.5%) (p < 0.001). Of the ten ODI items, patients in group I showed significant problems with lifting, sitting, standing, and travelling (p < 0.05). The most significant differences in the post-operative ODI were observed between patients who had undergone fusion at four or more levels and those who had undergone fusion at less than four levels (p = 0.005). The proportion of patients who were satisfied with their operations was similar in groups I and II (72.7% and 77.0%, respectively) (p = 0.668). The mean number of fused levels was associated with the post-operative ODI (r = 0.266, p = 0.003), but not with the post-operative VAS or satisfaction grade (p > 0.05). Post-operative functional disability was more severe in those with a long-level lumbar fusion, particularly at four or more levels, but patient satisfaction remained similar for those with both long- and short-level fusions

1. Six patients suffering from spontaneous posterior interosseous paralysis are described. 2. Two were due to benign tumour and four due to traumatic neuritis, three of which were associated with minor hyperextension injuries to the elbow joint and one with long standing cubitus varus. 3. Surgical exploration was performed in each patient with recovery of nerve function

1. A clinical condition is described in which there are symptoms of compression of the caudal nerve roots on standing or walking, but not at rest. Seven cases are reported. 2. Myelography showed a block in the lumbar region in every case. 3. At operation narrowing of the spinal canal in part of its lumbar course was found. 4. The nature of the abnormality is discussed. It is suggested that the narrowing is due to encroachment on the spinal canal by the articular processes

The results of 10 patients with severe rigid drop-foot corrected by the Lambrinudi triple arthrodesis were studied. The average amount of correction was 47 degrees, as evaluated from standing radiographs taken before and after operation. Radiological features of osteoarthritis and of flattening of the talus were common, but the feet were painless when reviewed at an average of 70 months later. A satisfactory range of movement was obtained at the ankle joint

Aims

Morphological abnormalities are present in patients with developmental dysplasia of the hip (DDH). We studied and compared the pelvic anatomy and morphology between the affected hemipelvis with the unaffected side in patients with unilateral Crowe type IV DDH using 3D imaging and analysis.

Aims

Complex total hip arthroplasty (THA) with subtrochanteric shortening osteotomy is necessary in conditions other than developmental dysplasia of the hip (DDH) and septic arthritis sequelae with significant proximal femur migration. Our aim was to evaluate the hip centre restoration with THAs in these hips.

A system for assessment of function after major pelvic injuries is proposed. This numerical system developed from a five-year prospective study of 60 patients. Five factors were assessed and scored: pain, standing, sitting, sexual intercourse and work performance. The total score then gave a clinical grade as excellent, good, fair or poor. The scoring system allows comparison between early and late results and also between various methods of treatment

An anteroposterior radiograph of the leg to include the hip and ankle, taken with the patient standing, provides an estimate of the line of load-bearing at the knee. Gait analysis may be used to determine the way in which the load in the knee is shared between the medial and lateral compartments during normal walking. A comparison of the results from the two methods, carried out on a group of 47 patients, led to the conclusion that both calculations are required for the successful outcome of a tibial osteotomy or a total arthroplasty

A survey of 6000 schoolchildren discovered 36 cases of unilateral and 60 cases of bilateral hallux valgus, defined as a metatarsophalangeal angle of more than 14.5 degrees, measured on standing radiographs. Metatarsus primus varus was found not only in the early stages of hallux valgus but in the unaffected feet of children with unilateral hallux valgus. Adduction of the first metatarsal is not due to differential growth of the cortices of the first metatarsal nor is it a consequence of malalignment of the metatarsocuneiform joint. The intermetatarsal angle did not correlate with the angle of metatarsus adductus nor with the intercuneiform angle

Evidence suggests that the alleviation of pain is enhancedby a strong patient-clinician relationship and attending to a patient’s social and mental health. There is a limited role for medication, opioids in particular.

Orthopaedic surgeons can use comprehensive biopsychosocial strategies to help people recover and can work with colleagues who have the appropriate expertise in order to maximize pain alleviation with optimal opioid stewardship.

Preparing patients for elective surgery and caring for them after unplanned injury or surgery can benefit from planned and practiced strategies based in communication science.

Aims

It remains controversial whether patellofemoral joint pathology is a contraindication to lateral unicompartmental knee arthroplasty (UKA). This study aimed to evaluate the effect of preoperative radiological degenerative changes and alignment on patient-reported outcome scores (PROMs) after lateral UKA. Secondarily, the influence of lateral UKA on the alignment of the patellofemoral joint was studied.

Aims

The aims of this study were to determine the effect of osteophyte excision on deformity correction and soft tissue gap balance in varus knees undergoing computer-assisted total knee arthroplasty (TKA).

Aims

The aim of this study was to systematically compare the safety and accuracy of robot-assisted (RA) technique with conventional freehand with/without fluoroscopy-assisted (CT) pedicle screw insertion for spine disease.

Aims

The aim of the current study was to assess the reliability of the Ottawa classification for symptomatic acetabular dysplasia.

Degenerative changes of the knee often cause loss of extension. This may affect aspects of posture such as lumbar lordosis. A total of 366 patients underwent radiological examination of the lumbar spine in a standing position. The knee and body angles were measured by physical examination using a goniometer. Limitation of extension of the knee was significantly greater in patients whose lumbar lordosis was 30° or less. Lumbar lordosis was significantly reduced in patients whose limitation of extension of the knee was more than 5°. It decreased over the age of 70 years, and the limitation of extension of the knee increased over the age of 60 years. Our study indicates that symptoms from the lumbar spine may be caused by degenerative changes in the knee. This may be called the ‘knee-spine syndrome’
