Management of periprosthetic fractures of the humerus : a systematic review.

AIMS: The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature. METHODS: A systematic search was conducted using the National Institute for Health and Care Excellence Healthcare Databases Advance Search. For inclusion, studies had to report clinical outcomes following the management of periprosthetic fractures of the humerus. The protocol was registered on the PROSPERO database. RESULTS: Overall, 40 studies were included, involving a total of 210 patients. The fractures were reported using very heterogeneous classification systems, as were the functional outcome scores. A total of 60 patients had nonoperative treatment with a 50% rate of nonunion. Fixation was undertaken in 99 patients; successful union was obtained in 93 (93%). Revision of either the humeral stem or the whole arthroplasty was reported in 79 patients with a high rate of union (n = 66; 84%), and a mean rate of complications of 29% (0% to 41%). CONCLUSION: This study highlighted a lack of uniformity in classifying these fractures and reporting the outcome of their treatment. The results may help to inform decision-making with patients, particularly about the rate of complications of nonoperative treatment. There is a need to improve the reporting of the pattern of these fractures using a uniform classification system, and the harmonization of the collection of data relating to the outcome of treatment. Based on this review, we propose a minimum dataset to be used in future studies. Cite this article: Bone Joint J 2022;104-B(4):416-423.

Double calcaneal osteotomy with minimally invasive surgery for the treatment of severe flexible flatfeet.

BACKGROUND: Severe flexible flatfoot deformity in children and adolescents is a complex problem. Calcaneal lengthening remains the gold standard for surgical correction at this institution. However, in a minority of patients, inadequate correction of valgus is noted at surgery and a further calcaneal shift osteotomy is done. METHODS: We have conducted a retrospective review of ten patients who received 15 combined minimally invasive calcaneal shift and calcaneal lengthening osteotomies, which were all performed by the senior author. All patients had failed conservative treatment. We describe our technique for double calcaneal osteotomy combining minimally invasive surgery (MIS) for the medial calcaneal shift with traditional open calcaneal lengthening osteotomy for treating children and adolescents with severe flexible flatfoot deformity. RESULTS: The average shift achieved was 8.07 mm. The average improvement in Meary's angle was 14.99°. All of them had radiological and clinical union at 12 weeks. None of the patients developed sural nerve injury, wound breakdown, or infection of the MIS incision. CONCLUSION: In double calcaneal osteotomies, the MIS calcaneal medial shift technique can be used safely with potentially lower risks of wound complications and sufficient medial shift, compared to conventional open extensive surgery. IMPLICATIONS: MIS calcaneal shift osteotomy has an advantage over open conventional open technique in cases where the skin is under tension like in combined calcaneal lengthening osteotomy. With experience, the procedure can be faster than an open procedure.

Literature review and a case report of spontaneous subscapular abscess in a child.

Subscapular space is an uncommon site for abscess formation. There are only seven reports of subscapular abscesses in the literature. Only three of these cases are reported in children. We recently treated a child with subscapular abscess. We performed the literature search using a combination of the keywords: subscapular, scapular, abscess and infection. One case was diagnosed on post-mortem autopsy, and only three of these cases are reported in children. The organism was Staphylococcus aureus in five cases (two were methicillin-resistant S. aureus), Haemophilus influenzae in one case, and no organism was grown in the last case. (Patient received a course of empirical antibiotics and samples did not grow any organism.) We describe a case of spontaneous subscapular abscess in a 7-year-old boy. The abscess was visualised on magnetic resonance imaging (MRI), and the organism was identified as S. aureus bacteria. The abscess was treated surgically with debridement and antibiotics, and the patient had full recovery with no subsequent effects. Subscapular abscess needs high index of suspicion and early imaging investigation. MRI is the modality of choice for accurate diagnosis. Early intervention leads to favourable outcome, while delays in diagnosis can be fatal.

Antibiotic Prophylaxis in Adults With Open Tibial Fractures: What Is the Evidence for Duration of Administration? A Systematic Review.

Open tibial fractures are common injuries after high-energy trauma such as road traffic accidents. Infection is one of the main complications of open fractures. Broad-spectrum antibiotics have been used for prophylaxis and treatment of infection in these fractures. The duration of antibiotic prophylaxis remains controversial, especially for the different types and grades of open fractures. No complete review, to date, has been performed of published studies to demonstrate the wide variety of duration of antibiotic use in practice to prevent infection, especially in open tibial fractures. The purpose of the present study was to review the evidence in the current data regarding the duration of prophylactic antibiotic administration in open tibial fractures and to identify the optimum duration of administration of antibiotics to minimize the risk of infection in these fractures. We reviewed and evaluated all published clinical trials claiming or cited elsewhere as being authoritative regarding the duration of prophylactic antibiotic use in open tibial fracture management. A large number of studies reported antibiotic prophylaxis in open fractures; however, only 8 met the inclusion criteria set out for our review. Only 1 randomized, double-blind, prospective study examined the duration of prophylactic antibiotic administration in open tibial fractures. That study suggested a short course of antibiotics is as effective as a long course in infection prophylaxis. The results of the present review highlight the need for a rigorous randomized, double-blind, multicenter trial to establish an agreed protocol for the optimal length of prophylactic antibiotic administration in open tibial fractures.
