Exsanguination is the second most common cause of death in patients who suffer severe trauma. The management of haemodynamically unstable high-energy pelvic injuries remains controversial, as there are no universally accepted guidelines to direct surgeons on the ideal use of pelvic packing or early angio-embolisation. Additionally, the optimal resuscitation strategy, which prevents or halts the progression of the trauma-induced coagulopathy, remains unknown. Although early and aggressive use of blood products in these patients appears to improve survival, over-enthusiastic resuscitative measures may not be the safest strategy.

This paper provides an overview of the classification of pelvic injuries and the current evidence on best-practice management of high-energy pelvic fractures, including resuscitation, transfusion of blood components, monitoring of coagulopathy, and procedural interventions including pre-peritoneal pelvic packing, external fixation and angiographic embolisation.

The October 2023 Trauma Roundup³⁶⁰ looks at: Intramedullary nailing versus sliding hip screw in trochanteric fracture management: the INSITE randomized clinical trial; Five-year outcomes for patients with a displaced fracture of the distal tibia; Direct anterior versus anterolateral approach in hip joint hemiarthroplasty; Proximal humerus fractures: treat them all nonoperatively?; Tranexamic acid administration by prehospital personnel; Locked plating versus nailing for proximal tibia fractures: a multicentre randomized controlled trial; A retrospective review of the rate of septic knee arthritis after retrograde femoral nailing for traumatic femoral fractures at a single academic institution.

Purpose: Accurate acetabular cup positioning is essential to successful total hip arthroplasty (THA). Intra-operative navigation of the acetabular component can optimize positioning, but often necessitates registration of the pelvis in the supine position. The majority of surgeons use the lateral position, however, which hides commonly employed registration landmarks. The purpose of this study was to identify novel anatomical landmarks for use in navigated THA from the lateral approach. Method: We identified 156 patients that underwent pelvic CT scans for non-orthopaedic reasons from which 60 patients (mean age 62 years; 30 males, 30 females) were included in the study. CT scans were analyzed with sophisticated software (region grow, isosurface creation, and geometry overlay features). Saved coordinates from each scan were inputted into the program MATLAB (Mathworks, Natick, MA), v7.0, on a Macintosh-based workstation. A code was created to be able to calculate the normal vector for both planes and then calculate the angle formed between the normal vectors. The anterior plane (pubic tubercle (PT) and anterior superior iliac spine (ASIS)) was defined in addition to a series of lateral planes by retaining the ipsilateral PT and ASIS from the anterior plane, plus a variable third landmark. Angles obtained were those between the anterior and lateral planes. Angle conversions between the planes were analyzed using a paired t-test with a p-value of < 0.05 accepted as significant. Results: The list of landmarks acquired included those used for supine registration (PT and ASIS) in addition to: posterior superior iliac spine (PSIS); posterior inferior iliac spine, (PIIS); ischial tuberosity (IT); tuber-culum of the iliac crest (TIC); and a line drawn along the outer lip of the iliac crest. The angle between the anterior plane and the novel lateral planes did not show a significant level of variance for two of the proposed lateral planes (P< 0.05). Conclusion: An imageless navigation system in THA that can be accurately employed in the lateral position will benefit many surgeons. The invariance in angle calculations for the lateral planes calculated using the PSIS and the TIC suggest that they could be novel pelvic landmarks for lateral plane registration

Aims: We evaluated the results of molecular diagnostics to see if they can help in conþrming an accurate diagnosis quickly in cases of Ewingñs sarcomas. Methods: We did biopsies and genetic studies in 19 patients (8 females, 11 males Ð 35±19 years old) with a bone tumor with clinical and imaging signs of Ewingñs sarcoma. Cytogenetic examination aimed at tracing characteristic products of the hybrid genes of the tumor. We did molecular analysis with RT-PCR. Results: In ten patients biopsy conþrmed the diagnosis of Ewingñs sarcoma. The genetic tests of 12 patients came to a clear conclusion. In 7 cases (4 Ewingñs sarcomas histologicaly) we had no answer. In seven cases we found products of hybrid genes Ews/Fli and Ews/Erg. These are the result of fusion of genes from chromosomes 22q12, 11q24 and 21q22 and the characteristic chromosomal translocation of Ewingñs sarcoma between exon 7 and exon 6 of the Fli fusion gene was conþrmed. Five cases had no characteristic numerical or structural chromosomal abnormalities. Histologic and cytogenetic diagnoses of Ewingñs sarcoma concur in þve cases. One case of Ewingñs sarcoma was not conþrmed with genetic diagnostics. Two cases with gene mutations characteris tic of Ewingñs sarcoma had an histologic diagnosis of an osteosarcoma. Conclusions: Malignant cells commonly exhibit speciþc chromosomal deletions, which may lead to tumor formation. Our cases show the strong relation between Ewingñs sarcoma and certain chimerical genetic transcriptions. Identical cytogenetical translocations in a few cases of other tumors and their absence in some Ewingñs sarcomas is confusing and indicates their common origin from a primitive tumor

Aims

The metabolic variations between the cartilage of osteoarthritis (OA) and Kashin-Beck disease (KBD) remain largely unknown. Our study aimed to address this by conducting a comparative analysis of the metabolic profiles present in the cartilage of KBD and OA.

We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity.

We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary.

Like athletes, musicians are vulnerable to musculoskeletal injuries that can be career ending or have a severe negative financial impact. All ages are affected, with a peak incidence in the third and fourth decades. Women are slightly more likely to be affected than men. It is incumbent upon orthopaedic surgeons to be able to complete a thorough physical assessment, be aware of the risk factors associated with musculoskeletal symptoms in musicians, and have a detailed knowledge of the specific syndromes they suffer and their appropriate treatment.

In this paper we review the common hand injuries that afflict musicians and discuss their treatment.
