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. Methods. Seven databases were searched for studies of HS and ACDF from inception of the study to 1 September 2019. Both random-effects and fixed-effects models were used to evaluate the overall effect of the C2-C7 range of motion (ROM), ROM of superior/inferior adjacent levels, adjacent segment degeneration (ASD),

Aims. Improvements in functional results and long-term survival are variable following conversion of hip fusion to total hip arthroplasty (THA) and complications are high. The aim of the study was to analyze the clinical and functional results in patients who underwent conversion of hip fusion to THA using a consistent technique and uncemented implants. Methods. A total of 39 hip fusion conversions to THA were undertaken in 38 patients by a single surgeon employing a consistent surgical technique and uncemented implants. Parameters assessed included Harris Hip Score (HHS) for function, range of motion (ROM), leg length discrepancy (LLD), satisfaction, and use of walking aid. Radiographs were reviewed for loosening, subsidence, and
Aims. Calcium sulphate has traditionally been used as a filler of dead space arising during surgery. Various complications have been described following the use of Stimulan bio-absorbable calcium sulphate beads. This study is a prospective observational study to assess the safety profile of these beads when used in revision arthroplasty, comparing the complication rates with those reported in the literature. Methods. A total of 755 patients who underwent 456 revision total knee arthroplasties (TKA) and 299 revision total hip arthroplasties (THA), with a mean follow-up of 35 months (0 to 78) were included in the study. Results. A total of 32 patients (4.2%) had wound drainage, and this was higher with higher bead volumes and in McPherson grade C patients. There was also a significantly higher bead volume in the 41 patients who developed hypercalcaemia, two of which were symptomatic (p < 0.0001). A total of 13 patients (1.7%) had

Introduction and Objective. Interest for direct anterior approach (DAA) in hip hemiarthroplasty (HHA) has greatly increased in recent years, however which is the best surgical approach in hip replacement treating femoral neck fractures (FNFs) is already unclear. The aim of this study is to perform a radiographic and perioperative complications analysis by comparing the direct anterior approach (DAA) with the direct lateral approach (DLA) in patients treated with hemiarthroplasty for FNFs. Materials and Methods. Patients with FNFs surgically treated between 2016–2020 with HHA were enrolled. The radiographical outcomes of DAA and DLA are compared. Several peri-operative and post-operative variables were evaluated: mean surgery time, complications as periprosthetic fractures or episodes of dislocation, the average of post-operative diaphyseal filling of the stem (Canal Fill Index, CFI), the extent of

Purpose. The ideal timing for a Total Hip Arthroplasty (THA) remains a highly controversial topic in the treatment of displaced acetabular fractures in the elderly with damage to the articular surface of the acetabulum or femoral head. Acute THA offers early rehabilitation but a high incidence of heterotopic ossification has been reported. Its incidence and consequences on the patient's function are not clear. The goal of this study is to compare the incidence of heterotopic ossification following acute THA of acetabular fractures compared to delayed THA, and to evaluate its functional effects on the patient. Method. In this retrospective consecutive case series of acetabular fractures; 20 patients were treated with acute THA and 20 patients were treated with delayed THA after failed conservative or surgical treatment. The incidence of heterotopic ossification (using Brooker's classification) was obtained and functional outcomes were evaluated using SF-12, WOMAC, Harris Hip Score surveys. Results.

Resurfacing arthroplasty of the hip is currently enjoying a resurgence in popularity. There are many reasons why resurfacing may be indicated, but one is that the absence of proximal femoral reaming at surgery may reduce the occurrence of
Introduction: As a result of the rapid increase in the number of hip resurfacing procedures performed, previously recognized complications have begun to recur; including, femoral neck fracture and heterotopic ossification. Hip resurfacing entails reaming of the femoral head to the appropriate size and significant bone debris produced, usually dispersed in the soft tissues. We advocate the use of a novel technique whereby the bone debris produced is collected and removed effectively without soft tissue spillage and ultimately reducing the incidence of heterotopic ossification. Materials and Methods: A 60-ml. plastic ‘galli pot’ is prepared by cutting the floor of the container, leaving behind a rim for collecting the bone debris. The container is placed over the femoral head and across the femoral neck. The femoral reamer is applied onto the femoral head with the container in-situ and reaming commenced. The bone debris produced is collected in the container, which is removed after completing the reaming process. Results: This technique was used effectively on patients undergoing hip resurfacing procedures using the Cormet hip (Corin Medical, Cirencester, UK) and the Birmingham Hip Resurfacing (Midland Medical Technologies, Birmingham, UK). The technique proved successful in collecting the bone debris produced and reducing bone debris in surrounding soft tissues. Discussion:
