An unusual presentation of metastatic melanoma in the shoulder.

A 72-year-old lady underwent a Copeland hemiarthoplasty of the shoulder for rotator cuff arthropathy with a good functional outcome. Her past medical history included previous management of a malignant melanoma. Several years following arthroplasty surgery, she acutely developed signs and symptoms of prosthetic joint infection. The present case report describes the metastatic spread of malignant melanoma mimicking that of prosthetic sepsis.

The effect of the timing of antibiotics and surgical treatment on infection rates in open long-bone fractures: a 6-year prospective study after a change in policy.

Our current protocol in treating open long-bone fractures includes early administration of intravenous antibiotics and surgery on a scheduled trauma list. This represents a change from a previous protocol where treatment as soon as possible after injury was carried out. This review reports the infection rates in the period 6 years after the start of this protocol. Two hundred and twenty open long-bone fractures were reviewed. Data collected included time of administration of antibiotics, time to theatre and seniority of surgeon involved. The patients were followed up until clinical or radiological union occurred or until a secondary procedure for non-union or infection was performed. Clinical, radiological and haematological signs of infection were documented. If present, infection was classified as deep or superficial. Surgical debridement was performed within 6 h of injury in 45 % of cases and after 6 h in 55 % of cases. Overall infection rates were 11 and 15.7 %, respectively (p = 0.49). The overall deep infection rate was 4.3 %. There was also no statistically significant difference in the subgroups of deep (p = 0.46) and superficial (p = 0.78) infection. Intravenous antibiotics were administered within 3 h of injury in 80 % of cases and after 3 h in 20 % of cases. The infection rates were 14 and 12.5 %, respectively (p = 1.0). There was no statistically significant difference in the subgroups of deep (p = 0.62) and superficial (p = 0.73) infection. Further statistical analysis did not reveal a significant difference in infection rates for any combination of timing of antibiotics and surgical debridement. Infection rates where the most senior surgeon present was a consultant were 9.5 % as opposed to 16 % with the consultant not present, but this trend was not statistically significant. These results suggest that the change in policy may have contributed to an improvement of the deep infection rate to 4.3 % from the previous figure of 8.5 % although this decrease is not statistically significant. Surgeons may have had concerns that delaying theatre may lead to an increased infection rate, but these results do not substantiate this concern.

The outcome of manipulation under general anesthesia for the management of frozen shoulder in patients with diabetes mellitus.

HYPOTHESIS: Frozen shoulder has a greater incidence, more severe course, and resistance to treatment in patients with diabetes mellitus compared with the general population. We hypothesized that diabetic patients with frozen shoulder undergoing treatment with manipulation under general anaesthesia (MUA) would have the same outcome as patients without diabetes. MATERIALS AND METHODS: We retrospectively analyzed data collected during a 10-year period of referrals for frozen shoulder. In all cases, a standardized MUA protocol was followed once the diagnosis of frozen shoulder in the frozen phase was made; this included an early repeat MUA in individuals with recurrence. We compared outcomes for patients documented as having diabetes with a nondiabetic control group and assessed the effect of insulin dependence and frozen shoulder etiology within the diabetic group. RESULTS: Of a consecutive series of 315 frozen shoulders, 36 patients (39 shoulders) were included in the diabetic group, with 256 patients (274 shoulders) as controls. There was a significant improvement in range of movement and Oxford Shoulder Score (P all <.001), with no difference between diabetic and control groups at early or late follow-up (mean, 41 months). A repeat procedure was required in 36% of diabetic patients compared with 15% of control patients. Recurrence in the diabetic group was influenced by etiology (47% of primary vs 0% of secondary frozen shoulders) and insulin requirement (39% insulin-dependent vs. 31% non-insulin-dependent). CONCLUSION: We provide a strategy for the management of diabetic frozen shoulders using MUA and estimates of success and recurrence rates that may be useful when informing consent.

What are the essential medications in pallative care? - a survey of Australian palliative care doctors.

BACKGROUND: There is a disparity of availability and cost of drugs in the community for palliative care patients through the Pharmaceutical Benefits Scheme (PBS) compared to those available to inpatients in public hospitals. METHODS: The Joint Therapeutics Committee of the Australian and New Zealand Society of Palliative Medicine, Palliative Care Australia and the Clinical Oncological Society of Australia surveyed palliative care practitioners in Australia to compile a list of drugs they considered essential. RESULTS: Drugs nominated generally had good levels of evidence for use in palliative care, although many practitioners still used some without evidence of benefit. DISCUSSION: We are now working with the Commonwealth Department of Health and Ageing to agree on a list of drugs for specific palliative care indications. As a result, the first ever section in the PBS for a specific patient population has been created. There is a need for high quality studies in palliative care to determine the best drugs to add to the list.

Outcomes of total elbow arthroplasty for rheumatoid arthritis: comparative study of three implants.

BACKGROUND: As the English-language literature on prosthetic elbow arthroplasty contains only two comparative studies of implants in contemporary use, to our knowledge, comparisons of prosthetic performance is difficult. An improved knowledge of comparative outcomes would be valuable in guiding implant selection. METHODS: We identified three groups of consecutive patients who had undergone prosthetic elbow arthroplasty with the Souter-Strathclyde, Kudo, or Coonrad-Morrey implant for the treatment of rheumatoid arthritis. There were thirty-three elbows in each group. All procedures were done by or under the supervision of one surgeon. Surviving patients in whom the elbow had not been revised were followed for a mean of sixty-one months after treatment with the Souter-Strathclyde implant, sixty-seven months after treatment with the Kudo implant, and sixty-eight months after treatment with the Coonrad-Morrey implant. Clinical function was assessed on the basis of pain relief and the range of flexion. Survivorship was assessed with use of a life-table method, with revision surgery and radiographic signs of loosening as the end points. RESULTS: The groups were comparable in terms of age, sex, and mean duration of follow-up. All three implant procedures relieved pain. Sustained improvement in the range of flexion was comparable among the three groups, with no implant procedure dramatically changing the fixed flexion deformity and all three improving maximum flexion. Revision surgery was needed because of infection, dislocation, and aseptic loosening. Survival of the Coonrad-Morrey implant was better than that of the other two implants. The five-year survival rates, with revision and radiographic signs of loosening as the end points, were 85% and 81% for the Souter-Strathclyde implant, 93% and 82% for the Kudo implant, and 90% and 86% for the Coonrad-Morrey implant. While radiographic evidence of loosening of the Coonrad-Morrey implants was less common, we noted focal osteolysis adjacent to 16% of these ulnar components and half of these cases progressed to frank loosening. CONCLUSIONS: The clinical function of these implants was similar in terms of pain relief and range of motion. We believe that component linkage with the Coonrad-Morrey implant prevents dislocation without increasing the risk of loosening.

Spontaneous rupture of the popliteus tendon in a 74-year-old woman and review of the literature.

Spontaneous rupture of the popliteus tendon has not previously been reported. We report the case of a 74-year-old patient, discuss its diagnosis and management, and review the current literature on isolated popliteus lesions. A multi-database electronic literature review suggests that the injury is invariably traumatic and has essentially been reported only in young, active individuals. It should be suspected in a patient with acute lateral knee pain who, on examination, has a hemarthrosis and a stable, possibly locked knee. The diagnosis is readily made using arthroscopy. While both conservative treatment with physiotherapy and open repair have been advocated, we describe a successful outcome of arthroscopic resection in an elderly patient and propose that popliteus injury is not confined to a younger age group. The balance of opinion in the current literature is that acute traumatic rupture in the young patient is managed by primary surgical repair, but successful outcome is also reported with nonoperative treatment.
