Early Mobilization in a Removable Cast Compared with Immobilization in a Cast after Operative Treatment of Ankle Fractures: A Prospective Randomized Study:

Background: The aim of operative treatment for ankle fractures is to allow early movement after internal fixation. The hypothesis of this study was that early mobilization would improve functional recovery in patients after surgery for ankle fractures. Methods: In a prospective randomized controlled study, 66 consecutive patients with ankle fractures that required open reduction and internal fixation (ORIF) were assigned to one of two postoperative regimens: immobilization in a nonweightbearing below-knee cast or early mobilization in a removable cast. Four patients were excluded from the study, leaving 62 for review. Results: Patients who had early mobilization in a removable cast had higher functional scores (Olerud-Molander and AOFAS) at 9 and 12 weeks postoperatively. They also returned to work earlier (67 days) compared with those treated in nonweightbearing below-knee cast (95 days), p < 0.05. There was no statistical difference in Quality of Life (SF-36 Questionnaire) at 6 months between the two groups. We had an approximately 10% postoperative infection trend (one superficial and two deep) in the early mobilization group. Conclusion: Despite the overall short-term benefit of early mobilization, we had three patients in the early mobilization group who had wound complications. Both the surgeon and patient should be aware of the higher risk of wound complications associated with this treatment, and thus the accelerated rehabilitation protocol should be individualized.

INTER AND INTRA-OBSERVER VARIABILITY ASSOCIATED WITH THE USE OF THE MIRELS’ SCORING SYSTEM FOR METASTATIC BONE LESIONS

Metastatic bone disease is increasing in association with ever-improving medical management of osteophylic malignant conditions. The precise timing of surgical intervention for secondary lesions in long bones can be difficult to determine. This paper aims to evaluate a classic scoring system. All radiographs were examined twice by three orthopaedic oncologists and scored according to the Mirels’ scoring system. The Kappa statistic was used for the purpose of statistical analysis. The results show agreement between observers (κ = 0.35–0.61) for overall scores at the two time intervals. Inter-observer agreement was also seen with subset analysis of size (κ = 0.27–0.60), site (κ = 0.77–1.0) and nature of the lesion (κ = 0.55–0.81). Similarly, low levels of intra-observer variability were noted for each of the three surgeons (κ= 0.34, 0.39, and 0.78, respectively). These results indicate a reliable, repeatable assessment of bony metastases. We continue to advocate its use in the management of patients with long bone metastases.

Attitudes of the medical profession to whole body and organ donation

Cadaveric dissection remains an important part of undergraduate medical education in anatomy. In a concerted effort to rise the number of doctors in practice in Ireland the amount of medical school placements has been increased steadily since 1995. This poses a problem as the number of cadavers has remained unchanged despite an overall increase in the population Ireland over the last twenty years. The medical profession plays a central part in raising public awareness of living and post-mortem organ donation. Previous studies have examined the attitudes of medical students to whole body donation, however to our knowledge this is the first study that evaluates the attitudes of medical professionals. We assess the opinions of junior and senior doctors at the time of their dissection experience and in their current practice. We show that their attitudes have changed as their clinical experience grows.

Resection and reconstruction of pelvic and extremity soft tissue sarcomas with major vascular involvement: Current concepts

Soft tissue sarcoma accounts for approximately 1% of all cancers diagnosed annually in the United States. When these rare malignant mesodermal tumours arise in the pelvis and extremities, they may potentially encase or invade large calibre vascular structures. This presents a major challenge in terms of safe excision while also leaving acceptable surgical margins. In recent times, the trend has been towards limb salvage with vascular reconstruction in preference to amputation. Newer orthopaedic and vascular reconstructive techniques including both synthetic and autogenous graft reconstruction have made complex limb-salvage surgery feasible. Despite this, limb-salvage surgery with concomitant vascular reconstruction remains associated with higher rates of post-operative complications including infection and amputation. In this review we describe the initial presentation and investigation of patients presenting with soft tissue sarcomas in the pelvis and extremities, which involve vascular structures. We further discuss the key surgical reconstructive principles and techniques available for the management of these complex tumours, drawn from our institutions experience as a national tertiary referral sarcoma service.

Musculoskeletal oncology training during residency

Purpose. To evaluate the efficacy of a musculoskeletal oncology training module during residency. Methods. 24 orthopaedic residents with differing years of experience were recruited. 12 of them received musculoskeletal oncology training for 6 months. The remaining 12 were controls who did not attend the training and had no clinical experience in a musculoskeletal oncology unit but had at least 3 years of postgraduate surgical training. Upon completion, residents in both groups were assessed by a knowledge test and then an objective structured clinical examination (OSCE). Results. Residents who attended the training module had better mean knowledge test scores (48 vs 25 out of 58, p<0.0001) and OSCE scores (32 vs 22 out of 42, p<0.004), compared to those who did not attend. No residents who attended the training module marked an inappropriate biopsy site that would have compromised definitive surgery, compared to 5 (42%) of the untrained residents who marked an inappropriate biopsy site that may have resulted in an unnecessary amputation. All residents who attended the training module agreed that such a module should be included in the orthopaedic residency programme. Conclusion. Residents who attended the training module were more aware of the biopsy principles and risks. A training module for musculoskeletal oncology should be included in the orthopaedic residency programme.

Pathological fracture of femur secondary to infected synovial sarcoma

Pathological fracture is not uncommon in musculoskeletal oncological surgical practice. When complicated by infection, it is both limb- threatening and life-threatening problem. Pathological fractures require urgent investigation, not urgent treatment. We present the case of a 75-year-old man who presented with an infected sarcoma causing a pathological fracture of his right femur.
