Ultrasound (US) was used to determine the congruity of the shoulder in 22 children with a deformity of the shoulder secondary to chronic obstetric brachial plexus palsy. There were 11 boys and 11 girls with a mean age of 4.75 years (0.83 to 13.92). The shoulder was scanned in the axial plane using a posterior approach with the arm internally rotated. The humeral head was classified as being either congruent or incongruent. The US appearance was compared with that on clinical examination and related to the intraoperative findings. All 17 shoulders diagnosed as incongruent on US were found to be incongruent at operation, whereas three diagnosed as congruent by US were found to be incongruent at operation. The diagnostic accuracy of US for the identification of shoulder incongruity was 82% when compared with the findings at surgery. US is a valuable, but not infallible tool, for the detection of incongruity of the shoulder

From 1970 to 1978, 29 patients had a unilateral operation for bilateral recurrent dislocation of the patella. We examined 21 of them at a mean of 14 years postoperatively. Eighteen of these patients had evidence of generalised joint laxity. Six of the operated knees and four of the unoperated knees still had recurrent dislocations. The operated knees were clinically worse, with a significantly higher incidence of osteoarthritis. We concluded that the operations used to treat recurrent dislocation of the patella may have had short-term benefits, but did not cure the patients in the long term

Arthroscopy of the knee is one of the most commonly performed orthopaedic procedures worldwide. Large-volume outcome data have not previously been available for English NHS patients. Prospectively collected admissions data, routinely collected on every English NHS patient, were analysed to determine the rates of complications within 30 days (including re-operation and re-admission), 90-day symptomatic venous thromboembolism and all-cause mortality. There were 301 701 operations performed between 2005 and 2010 – an annual incidence of 9.9 per 10 000 English population. Of these, 16 552 (6%) underwent ligament reconstruction and 106 793 (35%) underwent meniscal surgery. The 30-day re-admission rate was 0.64% (1662) and 30-day wound complication rate was 0.26% (677). The overall 30-day re-operation rate was 0.40% (1033) and the 90-day pulmonary embolism rate was 0.08% (230), of which six patients died. 90-day mortality was 0.02% (47). Age < 40 years, male gender and ligament reconstruction were significantly associated with an increased rate of 30-day re-admission and unplanned re-operation. In addition, a significant increase in 30-day admission rates were seen with Charlson comorbidity scores of 1 (p = 0.037) and ≥ 2 (p <  0.001) compared with scores of 0, and medium volume units compared with high volume units (p < 0.001). Complications following arthroscopy of the knee are rare. It is a safe procedure, which in the majority of cases is performed as day case surgery. These data can be used for quality benchmarking, in terms of consent, consultant re-validation and individual unit performance

Aims

Modular dual mobility (DM) prostheses in which a cobalt-chromium liner is inserted into a titanium acetabular shell (vs a monoblock acetabular component) have the advantage of allowing supplementary screw fixation, but the potential for corrosion between the liner and acetabulum has raised concerns. While DM prostheses have shown improved stability in patients deemed ‘high-risk’ for dislocation undergoing total hip arthroplasty (THA), their performance in young, active patients has not been reported. This study’s purpose was to assess clinical outcomes, metal ion levels, and periprosthetic femoral bone mineral density (BMD) in young, active patients receiving a modular DM acetabulum and recently introduced titanium, proximally coated, tapered femoral stem design.

Between 1992 and 1994 we performed a prospective study of the effect of total knee replacement (TKR) on the health status of 119 patients over the age of 80 years who had had a primary unilateral TKR. The Nottingham Health Profile was used to assess this before and at three and 12 months after operation. We found a significant improvement in the scores for pain, emotional reaction, sleep and physical mobility at three months. After 12 months, the scores for pain and sleep were well maintained. The other factors had deteriorated slightly but remained better than before operation. Our findings show that TKR leads to a significant improvement in the general health status of the very elderly

We report the results of low friction arthroplasty in 72 old tuberculous hips and 42 hips with old quiescent septic arthritis. Follow-up was for a minimum of two years. Recrudescence of tuberculosis was seen in only one patient, but deep infection occurred in four of the hips with previous septic arthritis. The reasons for this are discussed. It is recommended that patients with old tuberculous hips should have a course of anti-tuberculous drugs before operation, that patients with previous septic infection should have prophylactic antibiotics and antibiotic-loaded cement and that the operation should be performed by an experienced surgeon

We present 12 patients with synovial osteochondromatosis of the elbow treated by synovectomy. Histological review showed that seven cases were primary and five secondary osteochondromatosis. The patients with primary disease had a mean improvement in the flexion arc from a preoperative value of 40° to 123° to 5° to 128° when reviewed at a mean of nine years after operation. The secondary group had a mean improvement in the flexion arc from a preoperative value of 21° to 98° to 4° to 131° at a mean of 6.8 years after operation. There was recurrence in two of seven patients in the primary group and three of five in the secondary group. Osteoarthritis developed in six elbows in the primary and in three in the secondary group. Osteoarthritis secondary to synovial osteochondromatosis is progressive. In the established condition, the distinction between primary and secondary disease may be of greater histological than clinical relevance

We carried out a prospective study of 93 patients undergoing surgery for conditions of the rotator cuff during 1994 and 1995. They were assessed before operation and after six months, and four years, using the patient-based Oxford Shoulder Score (OSS), the SF-36 questionnaire and the Constant shoulder score. The response rates were higher for the OSS and SF-36. The correlation coefficients were high (r > 0.5) between all scores at each stage of the study. While all scores improved substantially at six months, the Constant score was reduced significantly at four years. This did not correlate with the patients’ judgement of the change in symptoms or of the success of the operation. Our study suggests that patient-based measures of pain and function can reliably assess outcomes in the medium term after surgery to the shoulder

Eleven patients underwent disarticulation for infected arthroplasty of the hip. Exchange total hip arthroplasty or conversion to a Girdlestone excision arthroplasty had been undertaken previously an average of 2.9 times. The indications for disarticulation were as a life-saving measure, or as a result of severe infection of soft tissue and bone, loss of bone stock, or vascular injury. While the indications for this drastic operation were highly individual, there were instances where disarticulation could have been avoided if repeated exchange operations had been eschewed in deference to a Girdlestone procedure

1. A rationale of subtrochanteric osteotomy with derotation and varus angulation in the treatment of Perthes' disease is suggested. 2. Three months after operation the child returns to a normal unrestricted life. 3. The anatomical results in twelve such operations with an average follow-up of two years and five months are presented. In five children the results were "very good," in four "good," in one "fair" and in one "bad.". 4. These results seem to compare favourably with those observed after conservative treatment of two, three or more years duration

1. A modification of the Keller's arthroplasty is described, in which one of two types of distractor–intramedullary wire and external staple–is used to maintain normal length of the great toe for three weeks after operation. 2. The results of the modified operation are analysed. They appear to show that the use of a distractor can be expected to produce an improved end result and to aid post-operative wound healing. 3. The possible reasons for the improvement in results are discussed. 4. The intramedullary wire and the external staple are compared with respect to ease of introduction, effectiveness in maintaining distraction and end results

1. "Reed" osteotomy has proved a satisfactory method for the correction of torsional deformity of the tibia and of associated minor varus or valgus deformity. 2. It is an "osteotomy in continuity" and maintains stability of the bone. 3. The position of the limb may be adjusted at the first change of plaster. 4. Three cases of non-union occurred in thirty-eight operations. 5. The operation should not be done on adults. Perhaps it may be wise to reserve it for even younger patients because its success depends on the pliability of cortical bone, which rapidly diminishes with increasing age

1. The term "bumper fracture" is colourful but usually inaccurate. The injury is a valgus split or crush. 2. A series of sixty bumper fractures is reported: forty-eight were treated without operation or plaster. 3. Twenty-seven of the forty-eight patients treated without splintage have been followed up for more than five years, and seventeen of these for more than ten years. 4. The results are satisfactory and there is no evidence that there is any late deterioration of the joint. 5. It is suggested that bumper fractures should be treated without operation and without fixation in plaster

1. A new operation of body-to-body intervertebral fusion by grafts introduced through a posterior approach is described. This is a preliminary report of early results, with follow-up to two years, which seems to be encouraging. 2. In spondylolisthesis, abnormal mobility of the loose posterior neural arch is believed in itself to cause nerve root pressure, and excision of the arch is an important part of the operation. 3. In the few cases where spinal fusion is needed after removal of a prolapsed intervertebral disc—and the proportion is now very low—posterior intervertebral fusion has proved very satisfactory

The administration of heparin during operation has been reported to enhance the efficacy of thromboprophylaxis in patients undergoing total hip replacement. We have performed a small pilot study in which intraoperative doses of heparin were given in addition to the usual postoperative thromboprophylaxis with enoxaparin in 32 patients undergoing total knee replacement. The primary endpoint was deep-vein thrombosis (DVT) as demonstrated by bilateral venography on 6 ± 2 days after operation. Sixteen patients developed DVT; in two the thrombosis was proximal as well as distal and in one the occurrence was bilateral. There was one major haemorrhage. These results are similar to those obtained with the use of postoperative thromboprophylaxis with enoxaparin alone. They do not provide support for the initiation of a larger randomised trial of this approach to management

We evaluated the efficacy of anterior fusion alone compared with combined anterior and posterior fusion for the treatment of degenerative cervical kyphosis. Anterior fusion alone was undertaken in 15 patients (group A) and combined anterior and posterior fusion was carried out in a further 15 (group B). The degree and maintenance of the angle of correction, the incidence of graft subsidence, degeneration at adjacent levels and the rate of fusion were assessed radiologically and clinically and the rate of complications recorded. The mean angle of correction in group B was significantly higher than in group A (p = 0.0009). The mean visual analogue scale and the neck disability index in group B was better than in group A (p = 0.043, 0.0006). The mean operation time and the blood loss in B were greater than in group A (p < 0.0001, 0.037). Pseudarthrosis, subsidence of the cage, and problems related to the hardware were more prevalent in group A than in group B (p = 0.034, 0.025, 0.013). Although the combined procedure resulted in a longer operating time and greater blood loss than with anterior fusion alone, our results suggest that for the treatment of degenerative cervical kyphosis the combined approach leads to better maintenance of sagittal alignment, a higher rate of fusion, a lower incidence of complications and a better clinical outcome

Aims

The purpose of this study was to examine whether leg-length discrepancy (LLD) following unilateral total hip arthroplasty (THA) affects the incidence of contralateral head collapse and subsequent THA in patients with bilateral osteonecrosis, and to determine factors associated with subsequent collapse.

There is little information available at present regarding the mechanisms of failure of modern metallic radial head implants. Between 1998 and 2008, 44 consecutive patients (47 elbows) underwent removal of a failed metallic radial head replacement. In 13 patients (13 elbows) the initial operation had been undertaken within one week of a fracture of the radial head, at one to six weeks in seven patients (seven elbows) and more than six weeks (mean of 2.5 years (2 to 65 months)) in 22 patients (25 elbows). In the remaining two elbows the replacement was inserted for non-traumatic reasons. The most common indication for further surgery was painful loosening (31 elbows). Revision was undertaken for stiffness in 18 elbows, instability in nine, and deep infection in two. There were signs of over-lengthening of the radius in 11 elbows. Degenerative changes were found in all but one. Only three loose implants had been fixed with cement. Instability was not identified in any of the bipolar implants

The Kodama-Yamamoto knee is an uncemented surface replacement which has been used since 1970. The design has been improved twice and this present report concerns the results of the Mark II model. Between 1980 and 1984, 350 knees were replaced in 225 patients. In 1987, a survey of 335 of these knees was conducted at two to seven years after operation. The results were excellent or good in 83% of patients. Many of the failures were because of general disorders unrelated to the operation, but in 5.4% of the knees there were local complications which continue to present problems

We prospectively followed 191 consecutive collarless polished tapered (CPT) femoral stems, implanted in 175 patients who had a mean age at operation of 64.5 years (21 to 85). At a mean follow-up of 15.9 years (14 to 17.5), 86 patients (95 hips) were still alive. The fate of all original stems is known. The 16-year survivorship with re-operation for any reason was 80.7% (95% confidence interval 72 to 89.4). There was no loss to follow-up, with clinical data available on all 95 hips and radiological assessment performed on 90 hips (95%). At latest follow-up, the mean Harris hip score was 78 (28 to 100) and the mean Oxford hip score was 36 (15 to 48). Stems subsided within the cement mantle, with a mean subsidence of 2.1 mm (0.4 to 19.2). Among the original cohort, only one stem (0.5%) has been revised due to aseptic loosening. In total seven stems were revised for any cause, of which four revisions were required for infection following revision of the acetabular component. A total of 21 patients (11%) required some sort of revision procedure; all except three of these resulted from failure of the acetabular component. Cemented acetabular components had a significantly lower revision burden (three hips, 2.7%) than Harris Galante uncemented components (17 hips, 21.8%) (p < 0.001). The CPT stem continues to provide excellent radiological and clinical outcomes at 15 years following implantation. Its results are consistent with other polished tapered stem designs
