Aims

The aim of this study was to determine whether national standards of best practice are associated with improved health-related quality of life (HRQoL) outcomes in hip fracture patients.

We used evoked spinal cord potentials (ESCP) for intraoperative diagnosis in 17 cases of traumatic brachial plexus palsy. Forty spinal nerves were directly stimulated during exploration of the brachial plexus and ESCP recorded from the cervical epidural space were compared with simultaneously observed somatosensory evoked potentials (SEP) and myelographic findings. Both SEP and ESCP could be evoked in 21 spinal nerves but ESCP were always more distinct and five to ten times greater in amplitude than SEP. In four nerves, ESCP but no SEP were produced, suggesting that there was continuity from the nerves to the spinal cord. ESCP were obtained from two spinal nerves which appeared to be abnormal on the myelogram. The results show that intraoperative electrodiagnosis by epidural ESCP recordings can provide useful information on the lesions of traumatic brachial plexus palsy

In 15 patients who underwent open exploration of the brachial plexus, the somatosensory evoked potentials and nerve action potentials recorded at the time of operation were useful as guides to the most appropriate surgical procedure, and also in predicting the outcome in certain lesions. In three patients the apparent normality of the upper trunk of the plexus was concealing a more proximal lesion which was irrecoverable. The presence of a somatosensory evoked potential showed functional continuity in three patients in whom the C7 root was clinically involved and who recovered after operation. In five patients proximal stumps of ruptured C5 roots showed functional central continuity; this indicated their suitability for grafting. These patients recovered except one who suffered from co-existing disease. The electrophysiological studies also confirmed the clinical diagnosis of avulsion of the C8 and T1 roots and therefore prevented unnecessary dissection

Scintigraphy using technetium-labelled methylene diphosphonate was performed on 110 scoliotic patients six months after an attempted fusion and the findings compared with those at exploration to detect the possible sites of pseudarthroses. The majority of patients (65 per cent) had a uniform uptake of isotope over the fused area and all but one had a solid fusion. A second group (35 per cent) had a more patchy uptake and eight of the nine patients with pseudarthroses were in this group. Pseudarthroses were detected as localised areas of increased uptake but there were also a number of false positives and scans that were difficult to interpret due to continuing new bone formation in immature fusions. In those scans performed after one year the pseudarthroses which had been missed were seen more clearly in contrast to the diminished generalised activity in the fused area

1. A syndrome resulting from congenital lesions affecting the spinal cord and cauda equina, associated with spina bifida occulta, is described. 2. The syndrome consists of a progressive deformity of the lower limbs in children. One foot and the same leg grow less rapidly than the other. The foot develops a progressive deformity which begins as a cavo-varus and becomes a valgus one. Both lower limbs may be affected. There may be progression to sensory loss, trophic ulceration, disturbance of function of bowel and bladder and even paraplegia. 3. Methods of investigation including myelography are described. 4. Exploration of the spinal cord has been undertaken in twenty-four patients so affected. Extrinsic congenital lesions causing traction or pressure or a combination of traction and pressure on the spinal cord have been found in twenty-two of these. 5. In two-thirds of the patients some degree of improvement has followed operation

It is clear that in lateral rhachotomy we have a procedure which is appropriate for approach to the vertebral bodies in a variety of pathological processes including, besides the relief of Pott's paraplegia, the treatment of non-paraplegic tuberculosis, the exploration of spinal tumours, the relief of certain types of traumatic paraplegia and the drainage of suppurative osteitis of the vertebral bodies. For tuberculous disease we find in lateral rhachotomy a technical procedure which provides a meeting point for the solution of several ideas. These are the evacuation of tuberculous abscesses as enunciated by Pott and developed by Ménard, the revascularisation of avascular areas, the removal of necrotic material and the direct removal of the features causing spinal cord compression. It is to the latter only that I think I have made a small contribution. For all other purposes, between lateral rhachotomy and the classical costo-transversectomy, the differences if any are extremely small. The fact remains that the direct surgical approach to lesions of the vertebral bodies has a wide scope of usefulness

The purpose of this paper is to call attention to the anterior bone block method of Hybbinette-Eden for recurrent dislocation of the shoulder joint. 1. The operative technique is not difficult, and the after-treatment is short and relatively agreeable for the patient. 2. Sixty of our own cases are described, with four recurrences. The recurrences all occurred as the result of real trauma. In a total of 128 Scandinavian cases there were eight recurrences—that is 6·3 per cent. 3. In our opinion, based on the observations of radiography, arthrography, and operation, it is the compression fracture of the head of the humerus which deserves the name "essential lesion." Destruction of the anterior rim of the glenoid may be very slight, or entirely lacking. No false joint cavity or rupture big enough to receive the head of the humerus was ever observed by arthrography or by inspection during operative exploration. Recurrent dislocation is an intracapsular subluxation, which occurs when the anterior rim of the glenoid slides into the hollow in the humeral head

Aims

As a proven and comprehensive molecular technique, metagenomic next-generation sequencing (mNGS) has shown its potential in the diagnosis of pathogens in patients with periprosthetic joint infection (PJI), using a single type of specimen. However, the optimal use of mNGS in the management of PJI has not been explored. In this study, we evaluated the diagnostic value of mNGS using three types of specimen with the aim of achieving a better choice of specimen for mNGS in these patients.

Deep gluteal syndrome is an increasingly recognized disease entity, caused by compression of the sciatic or pudendal nerve due to non-discogenic pelvic lesions. It includes the piriformis syndrome, the gemelli-obturator internus syndrome, the ischiofemoral impingement syndrome, and the proximal hamstring syndrome. The concept of the deep gluteal syndrome extends our understanding of posterior hip pain due to nerve entrapment beyond the traditional model of the piriformis syndrome. Nevertheless, there has been terminological confusion and the deep gluteal syndrome has often been undiagnosed or mistaken for other conditions. Careful history-taking, a physical examination including provocation tests, an electrodiagnostic study, and imaging are necessary for an accurate diagnosis.

After excluding spinal lesions, MRI scans of the pelvis are helpful in diagnosing deep gluteal syndrome and identifying pathological conditions entrapping the nerves. It can be conservatively treated with multidisciplinary treatment including rest, the avoidance of provoking activities, medication, injections, and physiotherapy.

Endoscopic or open surgical decompression is recommended in patients with persistent or recurrent symptoms after conservative treatment or in those who may have masses compressing the sciatic nerve.

Many physicians remain unfamiliar with this syndrome and there is a lack of relevant literature. This comprehensive review aims to provide the latest information about the epidemiology, aetiology, pathology, clinical features, diagnosis, and treatment.

In a prospective, randomised controlled trial, 68 children who had a completely displaced metaphyseal fracture of the distal radius were treated either by manipulation (MUA) and application of an above-elbow cast alone or by the additional insertion of a percutaneous Kirschner (K-) wire. Full radiological follow-up to union was obtained in 65 children and 56 returned for clinical evaluation three months after injury. Maintenance of reduction was significantly better in the K-wire group and fewer follow-up radiographs were required. There was no significant difference in the clinical outcome measured three months after injury. Seven of 33 patients in the MUA group had to undergo a second procedure because of an unacceptable position compared with none of the 35 in the K-wire group (chi-squared test, p < 0.01). One patient in the K-wire group required exploration for recovery of a migrated wire. We conclude that the use of a percutaneous K-wire to augment the reduction of the fracture in children who have a completely displaced metaphyseal fracture of the distal radius is a safe and reliable way of maintaining alignment of the fracture

Children with congenital focal deficiency of the proximal femur present many problems that are but rarely encountered by the individual surgeon who is thus unable to accumulate a wide experience. This paper reviews the literature and analyses the treatment of twenty-three cases at the Royal Children's Hospital, Melbourne, with the object of producing a rational plan of treatment. The management of instability of the hip, malrotation, inadequate proximal musculature and leg length inequality are separately considered for five grades of deficiency. Milder forms are amenable to subtrochanteric osteotomy to correct varus deformity. Exploration and grafting of the pseudarthrosis is indicated where progressive deformity develops. In the more severe deficiency, conservative management of the proximal bony defect provides a better result with an operation only rarely indicated. The gross leg length inequality may be most successfully overcome by Syme's amputation with subsequent fusion of the knee to create an above-knee amputee with an end-bearing stump allowing ready fitting of a prosthesis

1. Volkmann’s ischaemia is a real and threatening complication of fracture of the femur, and it is more common than reports in the literature would suggest. 2. The early signs and symptoms in the calf are ominous whereas the early vascular signs of a good tibial pulse, colour and temperature are often misleading. 3. Muscle decompression with or without arterial exploration has proved to be of no value. 4. Early recognition and radical treatment are imperative. Temporary paralysis of the lumbar sympathetic outflow has been shown to be an effective measure. 5. Transfixion of the calcaneum with a Kirschner wire for traction has the advantage of eliminating all bandages, suspending the tender calf and preventing an equinovarus deformity. 6. The only essential difference between the histological appearance of muscle which recovers and that which does not appears to be degeneration of muscle nuclei. The significance of engorged blood vessels remains in doubt. 7. Histological studies suggest that despite the typical gross appearance of an infarct some regeneration of muscle may occur

We carried out a randomised, controlled trial in 157 patients who had isolated severe Gustilo type-IIIa and type-IIIb fractures of the metaphysis or diaphysis of the leg to determine the prevalence of vascular injuries and the role of vascular repair. All patients had stable vital signs and clinically adequate circulation in their legs before operation. In a control group of 64 patients we performed conventional surgery with systematic debridement and primary stabilisation of the fractures. In the trial group of 93 patients the major vessels and nerves adjoining the compound fracture were routinely explored and repaired when necessary after the initial procedure. Two of the 28 control patients (7.1%) with type-IIIb compound fractures had signs of inadequate circulation after the first operation. Both had major vascular injuries which were demonstrated at a second procedure. In the trial group, major vascular injuries were found in two of 54 patients (3.7%) with type-IIIa and 11 of 39 patients (28.2%) with type-IIIb compound fractures. Compared with the control group the trial group showed improved results at both the immediate and long-term follow-up. Routine exploration and early repair of injured major vessels of the leg in severe compound fractures gave encouraging results

Forty-two consecutive patients with suspected lumbar disc protrusions were studied prospectively to compare the diagnostic accuracy of low-field strength MRI with that of radiculography. Thirty patients subsequently underwent surgical exploration at 33 levels and the operative findings were compared to both methods of diagnostic imaging. All patients had MRI studies, whilst 29 patients also had radiculography. Both studies were evaluated without prior knowledge of the clinical signs, operative findings or the results of other imaging techniques. MRI predicted the correct diagnosis in 29 of the 33 levels explored, an accuracy of 88%. All discs proven to be abnormal demonstrated a reduced signal from the nucleus pulposus. There were two false positive results and two doubtful cases but no false negatives. Radiculography predicted the correct diagnosis in 24 of 32 levels explored, an accuracy of 75%. There were two false positive results, five doubtfuls and one false negative. The overall accuracy when both tests were considered rose to 94%. Of the remaining 12 patients all except one showed good correlation between the MRI and radiculographic findings. These results indicate that low field strength MRI is slightly better than radiculography in diagnosing lumbar disc protrusions

The infrequency of serious cartilage destruction in the joints of children makes it probable that the majority will recover with antibiotic and constitutional treatment alone, especially if a joint biopsy is performed. Synovectomy for children should therefore be reserved for those whose knees remain swollen and warm, even after antibiotic therapy, or whose range of movement does not show signs of returning. Exploration of such joints may show that pannus is wholly or partly covering the cartilage and that it is soft and pitted. Removal of the pannus allows better nutrition of the cartilage. The number of children who require arthrodesis in the future should be very small. Adults who respond well to antibiotic and constitutional treatment may also recover without surgery, except biopsy, but for patients with more severe disease the need for an alternative to arthrodesis exists. The choice between synovectomy–better called joint clearance –can often only be made after the joint has been opened. The choice between the two operations has always been fully discussed with the patient before the operation. The results enumerated in this paper suggest that arthrodesis may only need to be performed for patients with severe disease, often involving the bony articular surfaces, and that joints may recover function even when there has been partial destruction of cartilage

We studied a consecutive series of 58 patients with penetrating missile injuries of the brachial plexus to establish the indications for exploration and review the results of operation. At a mean of 17 weeks after the initial injury, 51 patients were operated on for known or suspected vascular injury (16), severe persistent pain (35) or complete loss of function in the distribution of one or more elements of the brachial plexus (51). Repair of the nerve and vascular lesions abolished, or significantly relieved, severe pain in 33 patients (94%). Of the 36 patients who underwent nerve graft of one or more elements of the plexus, good or useful results were obtained in 26 (72%). Poor results were observed after repairs of the medial cord and ulnar nerve, and in patients with associated injury of the spinal cord. Neurolysis of lesions in continuity produced good or useful results in 21 of 23 patients (91%). We consider that a vigorous approach is justified in the treatment of penetrating missile injury of the brachial plexus. Primary intervention is mandatory when there is evidence of a vascular lesion. Worthwhile results can be achieved with early secondary intervention in patients with debilitating pain, failure to progress and progression of the lesion while under observation. There is cause for optimism in nerve repair, particularly of the roots C5, C6 and C7 and of the lateral and posterior cords, but the prognosis for complete lesions of the plexus associated with damage to the cervical spinal cord is particularly poor

1. The causes of pressure on the neuro-vascular bundle of the upper limb are many and varied. No one cause such as clavicular pressure can explain all cases. 2. Costo-clavicular pressure is not possible when there is a normal first rib and a normal thoracic outlet, but it is certainly a factor when the costo-clavicular interval is narrowed by the presence of a large cervical rib or an abnormal first thoracic rib. Clavicular pressure can act only during retraction and abduction, not in depression of the shoulder. 3. Temporary alterations in the radial pulse on movements of the shoulder in normal individuals are due to causes distal to the clavicle and have no relation to costo-clavicular pressure. 4. While irritation of sympathetic nerve fibres may explain the majority of cases of thrombosis, there are others in which clotting occurs in an aneurismal dilatation produced by pressure between the clavicle and the abnormal costal element. It is likely that the thrombosis occurs in an aneurism which has been present for some length of time. The cause of the aneurismal dilatation may be vaso-motor paralysis of a segment of the artery, ending distally at a point where a fresh intact leash of nerves is relayed to the vessel. 5. The importance of the scalenus anterior syndrome has been over-emphasised. If operative treatment is limited in all cases to anterior scalenotomy the results will be disappointing. 6. If operation is advised it should be performed without rigid and preconceived ideas, through an adequate incision, and with exploration wide enough to allow thorough investigation of the cause of pressure

Aims

To evaluate if union of clavicle fractures can be predicted at six weeks post-injury by the presence of bridging callus on ultrasound.
