Twelve cases of sternal injury associated with spinal fractures have been reviewed. The sternum is regularly buckled or fractured in patients with high thoracic spinal fractures. Our review suggests that sternal injuries may also be associated with spinal fractures outside this region, and with types of fracture other than crushing of vertebral bodies. Injury to the sternum, when due to indirect violence, is almost always associated with a severe spinal column injury. A displaced fracture of the thoracic spine, with or without an associated sternal fracture, can produce significant widening of the mediastinal shadow on a chest radiograph. This is caused by a paravertebral haematoma, and can be difficult to differentiate from widening due to an aortic rupture

Opinion varies as to the incidence of nerve lesions in anterior dislocation of the shoulder after low-velocity trauma. Most studies are retrospective or do not use EMG. We have investigated the incidence and the clinical consequences of nerve lesions in a prospective study by clinical and electrophysiological examination. Axonal loss was seen in 48% of 77 patients. The axillary nerve was most frequently involved (42%). Although recovery as judged by EMG and muscle strength was almost complete, function of the shoulder was significantly impaired in patients with lesions of the axillary and suprascapular nerves. Unfavourable prognostic factors are increasing age and the presence of a haematoma. It is not necessary to carry out EMG routinely; an adequate programme of physiotherapy is important. In patients with a severe paresis, EMG is essential after three weeks

Five patients with long-standing, severe rheumatoid arthritis who developed cervical myelopathy at the subaxial levels are presented. In each patient the myelopathy occurred in the absence of major subluxation. At laminectomy the cause of the cord compression was found to be a band-like mass of ligamentous and granulation tissue in the posterior half of the extradural space, extending to the underlying portion of the dura and forming a constricting ring. In three patients this constricting ring was released by longitudinal division of the dura followed by application of a fascial patch graft. This release seems to be essential for effective decompression of the cord and good neurological recovery was achieved in these three patients. Of the other two patients, the result was fair in one and poor in the other, this latter result being due to severe intra-operative bleeding with a massive wound haematoma

Aims

We have evaluated the survivorship, outcomes, and failures of an interlocking, reconstruction-mode stem-sideplate implant used to preserve the native hip joint and achieve proximal fixation when there is little residual femur during large endoprosthetic reconstruction of the distal femur.

Aims

The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major limb salvage surgery (LSS), or amputation.

1. Volkmann's ischaemia of the lower limb is more common in adults than in children and occurs with sufficient frequency after injuries of the femur, knee and leg to warrant a more determined effort to prevent it. 2. The first and most essential step is to recognise the early signs of ischaemic damage. Incision of the deep fascia may then save the threatened underlying muscle, though it may also be necessary to seek for and evacuate a haematoma beneath the muscle. When the femoral or popliteal artery is injured, exploration and repair may be imperative. 3. The treatment of established ischaemic contracture is by whatever measures are necessary to correct the deformity. These are lengthening of shortened tendons, or excision of them if they are involved in dense fibrosis at the periphery of the ischaemic mass; and excision of all totally destroyed muscle. Amputation may be necessary

1. Three cases of traumatic arterial spasm are reported. 2. In each case there was increased tension in a neighbouring myofascial compartment. 3. The cause of this tension was oedema, possibly supplemented in one case by haematoma. 4. Release of tension by splitting the sheath was followed by relaxation of the artery. 5. It is suggested that tension in a fascial compartment may provide the stimulus that maintains arterial spasm and that the consequent ischaemia aggravates the oedema, so that a vicious circle is established. 6. It is further suggested that if spasm persists in spite of the usual measures, including exploration of the artery, the distal myofascial compartment should be decompressed. Division of the deep fascia of the cubital or the popliteal fossa is not enough. 7. Such persistent arterial spasm is uncommon, and further observations are needed to define the significance of increased tension in a distal myofascial compartment

We studied 45 children who presented with an inversion injury of the ankle. The clinical signs suggested injury to the distal growth plate of the fibula, but the plain radiographs appeared normal. Ultrasound examination of the joint in 40 patients showed a subperiosteal haematoma consistent with a growth-plate injury in 23 (57.5%). Children who had been treated with a tubular bandage and crutches by random selection had a mean time to return of normal activity of 14.22 days compared with 21.60 days for those treated with a plaster-of-Paris cast (t = 3.60, p = 0.0032; d = 7.38, 95% CI 3.0 to 11.8). We conclude that children with inversion ankle injuries who have clinical signs of injury to the distal fibular growth plate but a normal radiological appearance, should be treated with a tubular bandage and crutches

We performed a randomised controlled study to compare heparin with the A-V Impulse System in the prevention of deep-vein thrombosis (DVT) in 132 consecutive patients undergoing total hip replacement. After the operation, all patients had compression stockings, 65 were treated with calcium heparin and 67 with the intermittent plantar pump. DVT was diagnosed by Doppler ultrasound and thermography, followed by phlebography. There were 23 cases of DVT (35.4%) in the heparin group, with 16 major and seven minor thromboses. In the impulse pump group there were nine cases (13.4%) with three major and six minor thromboses. The differences for all thromboses and for major thromboses were both significant at p < 0.005. In the heparin group there was one fatal pulmonary embolism and nine patients (13.8%) had excessive bleeding or wound haematomas, as against none in the impulse pump group

A balanced inflammatory response is important for successful fracture healing. The response of osteoporotic fracture healing is deranged and an altered inflammatory response can be one underlying cause. The objectives of this review were to compare the inflammatory responses between normal and osteoporotic fractures and to examine the potential effects on different healing outcomes. A systematic literature search was conducted with relevant keywords in PubMed, Embase, and Web of Science independently. Original preclinical studies and clinical studies involving the investigation of inflammatory response in fracture healing in ovariectomized (OVX) animals or osteoporotic/elderly patients with available full text and written in English were included. In total, 14 articles were selected. Various inflammatory factors were reported; of those tumour necrosis factor-α (TNF-α) and interleukin (IL)-6 are two commonly studied markers. Preclinical studies showed that OVX animals generally demonstrated higher systemic inflammatory response and poorer healing outcomes compared to normal controls (SHAM). However, it is inconclusive if the local inflammatory response is higher or lower in OVX animals. As for clinical studies, they mainly examine the temporal changes of the inflammatory stage or perform comparison between osteoporotic/fragility fracture patients and normal subjects without fracture. Our review of these studies emphasizes the lack of understanding that inflammation plays in the altered fracture healing response of osteoporotic/elderly patients. Taken together, it is clear that additional studies, preclinical and clinical, are required to dissect the regulatory role of inflammatory response in osteoporotic fracture healing.

Aims

Whether to perform hybrid surgery (HS) in contrast to anterior cervical discectomy and fusion (ACDF) when treating patients with multilevel cervical disc degeneration remains a controversial subject. To resolve this we have undertaken a meta-analysis comparing the outcomes from HS with ACDF in this condition.

We studied the effects of the timing of tourniquet release in 88 patients randomly allocated for release after wound closure and bandaging (group A), or before the quadriceps layer had been closed allowing control of bleeding before suture (group B). The groups were similar in mean age, weight, gender, preoperative knee score, radiographic grading, and prosthesis implanted. Patients in group B had less postoperative pain, achieved earlier straight-leg raising, and had fewer wound complications. Five patients in group A had to return to theatre, three for manipulation under anaesthesia, one for secondary closure of wound dehiscence, and one for drainage of a haematoma. The last patient later developed a deep infection, which was treated by a two-stage revision. There were no significant differences between the two groups in operating time, or the decrease in haemoglobin concentration at 48 hours postoperatively. Some of the adverse effects of the use of a tourniquet for knee surgery can be significantly reduced by early tourniquet release, with haemostasis before the quadriceps mechanism and the wound are closed

Aims

Periprosthetic fractures (PPFs) around cemented taper-slip femoral prostheses often result in a femoral component that is loose at the prosthesis-cement interface, but where the cement-bone interface remains well-fixed and bone stock is good. We aim to understand how best to classify and manage these fractures by using a modification of the Vancouver classification.

Aims

Infection after surgery increases treatment costs and is associated with increased mortality. Hip fracture patients have historically had high rates of methicillin-resistant Staphylococcus aureus (MRSA) colonization and surgical site infection (SSI). This paper reports the impact of routine MRSA screening and the “cleanyourhands” campaign on rates of MRSA SSI and patient outcome.

Aims

The direct posterior approach with subperiosteal dissection of the paraspinal muscles from the vertebrae is considered to be the standard approach for the surgical treatment of adolescent idiopathic scoliosis (AIS). We investigated whether or not a minimally-invasive surgery (MIS) technique could offer improved results.

Aims

As the population ages and the surgical complexity of lumbar spinal surgery increases, the preoperative stratification of risk becomes increasingly important. Understanding the risks is an important factor in decision-making and optimizing the preoperative condition of the patient. Our aim was to determine whether the modified five-item frailty index (mFI-5) and nutritional parameters could be used to predict postoperative complications in patients undergoing simple or complex lumbar spinal fusion.

Aims

The purpose of this study was to determine whether there were long-term differences in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years.

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.
