The present study sought to assess the clinical and radiological results and long-term joint impact of different techniques of lateral ankle ligament reconstruction.

Shoulder arthroplasty is the treatment of choice for a range of degenerative diseases. However, long term follow-up suggests almost half of patients graded their treatment as unsatisfactory. Component malalignment is thought the most likely cause. The anterior anatomical neck is used as a reference for the osteotomy. The objective of the study was to analyse the cartilage/metaphyseal interface to identify reference points that may recover version accurately. Twenty-four humeri were scanned using a Microscribe digitiser and surface laser scanner. Modelling software was used to analyse the Cartilage/metaphyseal interface. The retroversion angle was calculated for the normal geometry and for the standard osteotomy. An ideal osteotomy plane was then created for each specimen and the distance from the cartilage/metaphyseal interface determined, identifying points of least deviation. The reference points were used to simulate a new osteotomy for which retroversion was calculated. The novel osteotomy and traditional osteotomy were compared to the normal geometry. The mean retroversion for the normal geometry was 18.5±9.0 degrees. The mean retroversion for the traditional osteotomy technique was 29.5±10.7 degrees, significantly different from the original (p<0.001). The mean retroversion using the novel osteotomy was 18.9±8.9 degrees and similar to the normal geometry (p=0.528). The traditional osteotomy resulted in a mean increase in retroversion of 38%. The increase in version may result in eccentric loading at the glenoid and alter rotator cuff balance. The novel osteotomy resulted in more accurate recovery of head geometry and may improve clinical outcome

Aim and Purpose of the study. The authors evaluate the efficacy of athrodiatasis as possible alternative to arthrodesis or arthroplasty in the treatment of ankle arthritis in young patients. They present the long term results (average 19 years) of a small series of patients (10 cases) treated with a monolateral transarticular external fixator associated to different open or athroscopic procedures. Material and Methodology. The patients have been revaluated with the Kitaoka scoring scale associated to the x-ray evaluation. The authors will compare these results with those reported for the same series at an early evaluation (2,5 y of follow up) and with those published in literature. Discussion. Arthrodiatasis of the ankle with distraction and movement of the joint under weightbearing can guarantee an intermittent Hydrostatic pressure that has a trophyc effect on residual cartilage. In 1995 a new interest in ankle distraction was promoted by a very active Duch group which in few years demonstrated that there was still space for this indication as alternative to the arthrodesis in very young and active patients because the functional and physical impairment, the pain and mobility of this joint can be improved also after the first year of follow up. Our good results with the same approach seems to confirm their conclusions after a long term follow –up even if there is no correlation between the functional and radiological findings. It is important to underline that frequently is necessary to associate to arthrodiatasis other ancillary arthroscopic or open procedures in order to optimise the results. Conclusion. Arthodiatasis as possible alternative to arthrodesis or arthroplasty in the treatment of ankle arthritis is still a valid option in selected cases because can guarantee good functional results even at a long term follow-up

Aims

Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections.

Introduction. Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma. We review our experience to characterize its prevalence, treatment, relapse and survivorship at long term follow-up. Methods. Eighty-seven patients aged from 4 to 60 years (mean 20 years), were treated from 1985 to 2008. Lesions affected the femur (38), humerus (20), tibia (19), fibula (4), pelvis (3), foot (2) and radius (1). Eight patients had metastatic disease at diagnosis. Seventy-eight patients were treated with neoadjuvant chemotherapy with three or more drugs according to different protocols, nine had surgery as first treatment. Limb salvage surgery was performed in 71 cases, amputation in 14 and rotationplasty in one. One patient died before surgery. Prognostic factors were evaluated with Kaplan-Meier analysis. Results. At a mean follow-up of 8 years, overall survival was 81%, 65% and 65% at 2, 5 and 10 years respectively. Fifty-two patients were disease-free, three were alive with disease, twenty-nine died with disease and three died of other causes. Thirteen local recurrences were observed. Twenty-three patients developed lung (20) or bone (3) metastases. Pathologic fracture did not significantly influence survivorship. Prognostic influence of age of the patients was evaluated at three different cut-off (15, 20 and 25 years-old): younger patients had better survivorship, without statistical significance. Induced necrosis according to Huvos’ classification was significant at both univariate and multivariate regression Cox analysis (p=0.0001). Conclusion. TOS does not have a poor prognosis as previously reported in the literature. A high percentage of patients can be cured with neoadjuvant chemotherapy and surgery. In most patients, limb sparing surgery is possible and safe

In the time since Letournel popularised the surgical treatment of acetabular fractures, more than 25 years ago, there have been many changes within the field, related to patients, surgical technique, implants and post-operative care. However, the long-term outcomes appear largely unchanged. Does this represent stasis or have the advances been mitigated by other negative factors? In this article we have attempted to document the recent changes within the surgery of patients with a fracture involving the acetabulum, outline contemporary management, and identify the major problem areas where further research is most needed.

Aims

To evaluate the outcomes of cemented total hip arthroplasty (THA) following a fracture of the acetabulum, with evaluation of risk factors and comparison with a patient group with no history of fracture.

Limited access surgery is thought to reduce post-operative morbidity and provide faster recovery of function. The percutaneous compression plate (PCCP) is a recently introduced device for the fixation of intertrochanteric fractures with minimal exposure. It has several potential mechanical advantages over the conventional compression hip screw (CHS). Our aim in this prospective, randomised, controlled study was to compare the outcome of patients operated on using these two devices.

We randomised 104 patients with intertrochanteric fractures (AO/OTA 31.A1–A2) to surgical treatment with either the PCCP or CHS and followed them for one year postoperatively.

The mean operating blood loss was 161.0 ml (8 to 450) in the PCCP group and 374.0 ml (11 to 980) in the CHS group (Student’s t-test, p < 0.0001). The pain score and ability to bear weight were significantly better in the PCCP group at six weeks post-operatively. Analysis of the radiographs in a proportion of the patients revealed a reduced amount of medial displacement in the PCCP group (two patients, 4%) compared with the CHS group (10 patients, 18.9%); Fisher’s exact test, p < 0.02.

The PCCP device was associated with reduced intra-operative blood loss, less postoperative pain and a reduced incidence of collapse of the fracture.
