Of 48 consecutive children with Gartland III supracondylar fractures, 11 (23%) had evidence of vascular injury, with an absent radial pulse. The hand was pink and warm in eight and white and cold in the other three patients. They underwent colour-coded duplex scanning (CCDS) and ultrasound velocimetry (UV) to investigate the patency of the brachial artery and arterial blood flow. In seven patients with a pink pulseless hand, CCDS showed a displaced, kinked and spastic brachial artery and a thrombosis was present in the other. In all cases UV showed reduced blood flow in the hand. In three patients with a white pulseless hand, scanning demonstrated a laceration in the brachial artery and/or thrombosis. In all cases, the fracture was reduced under general anaesthesia and fixed with Kirschner wires. Of the seven patients with a pink pulseless hand without thrombosis, the radial pulse returned after reduction in four cases. The remaining three underwent exploration, along with the patients with laceration in the brachial artery and/or thrombosis.

We believe that the traditional strategy of watchful waiting in children in whom the radial pulse remains absent in spite of good peripheral perfusion should be revisited. Vascular investigation using these non-invasive techniques that are quick and reliable is recommended in the management of these patients.

Osteotomies are commonly carried out in orthopaedic surgery, particularly in limb reconstruction. Complications are uncommon provided that sufficient care is taken and a sound technique used. We describe three cases of formation of false aneurysm after osteotomy, with acute, delayed and asymptomatic onset. The diagnosis was supported by ultrasound investigation, and confirmed by angiography. Embolisation with coils was a successful method of treatment. We recommend a safe method of osteotomy with good bone exposure and adequate soft-tissue protection.

We adduce the following conclusions from our experience of using this spring-loaded compression screw on completely displaced medial fractures of the femoral neck:. 1. That this method probably eliminates non-union when the head is fully viable. 2. That primary "first-intention" osseous union occurs in approximately 33·3 per cent of cases. 3. That a vascular complication, of varying severity, undetectable by orthodox radiological tests, is revealed by extrusion of the screw in 66·6 per cent of cases. 4. That these observations disprove the idea that the main obstacle to revascularisation of an ischaemic head is the existence of forces so inclined to the axis of the femoral neck as to cause "shear.". 5. That, compared with the Smith-Petersen nail used for completely displaced fractures, continuous spring compression can materially reduce the incidence of utter mechanical failure within the first year after operation. This is the result of "mushroom" impaction which itself can resist shearing strain and so can permit function as a fibrous union. 6. That early and rapid extrusion is a sensitive indication of a vascular complication in the head. Forewarned by this, activity can be restricted, or possibly other measures adopted, to anticipate or permanently postpone serious trouble

Aims

Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft.

Aims

Vascular compromise due to arterial injury is a rare but serious complication of a proximal humeral fracture. The aims of this study were to report its incidence in a large urban population, and to identify clinical and radiological factors which are associated with this complication. We also evaluated the results of the use of our protocol for the management of these injuries.

Aims

The aim of this study was to reassess the rate of neurological, psoas-related, and abdominal complications associated with L4-L5 lateral lumbar interbody fusion (LLIF) undertaken using a standardized preoperative assessment and surgical technique.

Aims

To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration.

Aims. Periacetabular osteotomy is an effective way of treating symptomatic hip dysplasia. We describe a new minimally invasive technique using a modification of the Smith-Peterson approach. We performed a prospective, longitudinal cohort study to assess for any compromise in acetabular correction when using this approach, and to see if the procedure would have a higher complication rate than that quoted in the literature for other approaches. We also assessed for any improvement in functional outcome. Patients and Methods. From 168 consecutive patients (189 hips) who underwent acetabular correction between March 2010 and March 2013 we excluded those who had undergone previous pelvic surgery for DDH and those being treated for acetabular retroversion. The remaining 151 patients (15 men, 136 women) (166 hips) had a mean age of 32 years (15 to 56) and the mean duration of follow-up was 2.8 years (1.2 to 4.5). In all 90% of cases were Tönnis grade 0 or 1. Functional outcomes were assessed using the Non Arthritic Hip Score (NAHS), University of California, Los Angeles (UCLA) and Tegner activity scores. Results. The mean pre-operative lateral centre-edge angle was 14.2° (-5° to 30°) and the mean acetabular index was 18.4° (4° to 40°). Post-operatively these were 31° (18° to 46°) and 3° (-7° to 29°), respectively, a significant improvement in both (p < 0.001). Allogenic blood transfusion was required in two patients (1.2%). There were no major nerve or vascular complications, and no wound infections. At the time of last follow-up, we noted a significant improvement in functional outcome scores: UCLA improved by 2.31 points, Tegner improved by 1.08 points, and the NAHS improved by 25.4 points (p < 0.001 for each). Hypermobility and longer duration of surgery were significant negative predictors for a good post-operative UCLA score, while residual retroversion was a positive predictor of post-operative UCLA score. Conclusion. We have found this approach to be safe and effective, facilitating early recovery from surgery. Cite this article: Bone Joint J 2017;99-B:22–8

Aims

Developmental dysplasia of the hip (DDH) describes a pathological relationship between the femoral head and acetabulum. Periacetabular osteotomy (PAO) may be used to treat this condition. The aim of this study was to evaluate the results of PAO in adolescents and adults with persistent DDH.

Over a 25-year period, 12 patients had from 2.5 to 5.1 cm operative shortening of the tibia and fibula for leg length discrepancy at between four and 18 years of age. All recovered normal function and there was minor cosmetic impairment in only two cases. The only vascular complication was temporary delay in return of the circulation to the foot after tourniquet removal in one patient. The procedure is valuable for discrepancy of tibial length in patients when they present too late for epiphyseal arrest, when there is doubt as to the appropriate timing for epiphyseal arrest, or when it is uncertain at an earlier stage whether there is need for surgical correction

Aims

To compare rates of serious adverse events in patients undergoing revision knee arthroplasty with consideration of the indication for revision (urgent versus elective indications), and compare these with primary arthroplasty and re-revision arthroplasty.

1. Two inches of lengthening may be gained in the femur, and three inches in the tibia and fibula, without complication. 2. More than this may be secured at the risk of temporary external popliteal paresis. 3. Lengthening of the tibia and fibula is more certain and more easy to control than lengthening of the femur. 4. Traction, and counter-traction through the bone, with complete lateral rigidity, are essential to success. 5. In applying this technique to the femur there is a danger of knee stiffness. The farther from the knee the skeletal traction pins are inserted, the less is the risk. The operation should therefore be planned as high as possible in the shaft of the femur. 6. The most delicate structure, and the one least tolerant of stretching, is the external popliteal nerve. 7. An oblique osteotomy, started by closely spaced drill-holes, is the best. 8. Certain vascular complications experienced by other surgeons are attributable to subperiosteal bone exposure, and to dividing the periosteum and fascial structures transversely

1. After limb injuries with loss of skin and subcutaneous tissue, full-thickness skin flaps afford the most satisfactory cover. It is particularly important to replace unstable and scarred skin before attempting bone reconstruction and similar operations. 2. In the leg and foot, full-thickness skin cover is conveniently obtained by the cross-leg flap technique. The blood supply of such flaps is considered and the technique of operation is described. Free excision of avascular scar tissue is essential. 3. "Delayed transfer" of the flap is advisable unless conditions are favourable; two methods are considered. 4. Immobilisation in plaster is the most satisfactory method of fixation of the limbs after attachment of the flap. Muscle exercises are performed throughout the period of treatment in order to minimise joint stiffness and shorten convalescence. 5. The cross-leg flap technique should not usually be used in children, young women, or the aged and mentally infirm. Contra-indications include arthritis of the knee and hip joints because there is danger of joint stiffness. 6. Vascular complications of cross-leg skin grafting are discussed

Aims

The objective of this study was to evaluate the clinical and radiological outcomes of patients younger than six months of age with developmental dysplasia of the hip (DDH) managed by either a Pavlik harness or Tübingen hip flexion splint.

Aims

The aim of this retrospective study was to compare the correction achieved using a convex pedicle screw technique and a low implant density achieved using periapical concave-sided screws and a high implant density. We hypothesized that there would be no difference in outcome between the two techniques.

Aims

Inadvertent soft tissue damage caused by the oscillating saw during total knee arthroplasty (TKA) occurs when the sawblade passes beyond the bony boundaries into the soft tissue. The primary objective of this study is to assess the risk of inadvertent soft tissue damage during jig-based TKA by evaluating the excursion of the oscillating saw past the bony boundaries. The second objective is the investigation of the relation between this excursion and the surgeon’s experience level.

Aims

We conducted a systematic review and meta-analysis to compare the mortality, morbidity, and functional outcomes of cemented versus uncemented hemiarthroplasty in the treatment of intracapsular hip fractures, analyzing contemporary and non-contemporary implants separately.

Aims

The aims of this study were to determine the rates of surgical complications, reoperations, and readmissions following herniated lumbar disc surgery, and to investigate the impact of sociodemographic factors and comorbidity on the rate of such unfavourable events.

Aims

We set out to determine if there is a difference in perioperative outcomes between early and delayed surgery in paediatric supracondylar humeral fractures in the absence of vascular compromise through a systematic review and meta-analysis.
