Wound Leakage With the Use of Calcium Sulphate Beads in Prosthetic Joint Surgeries: A Systematic Review.

Since its first use as a bone void filler at the end of the 19th century, calcium sulphate products have been adapted in different ways to aid orthopaedic surgeons. Calcium sulphate local antibiotic delivery systems offer a promising solution in the delivery of high antibiotic concentrations locally for an extended period of time. Over the years, multiple centres have reported side effects such as wound drainage, heterotrophic ossification and hypercalcaemia. This study was carried out to assess the risk of wound drainage in prosthetic joints after implantation of antibiotic-impregnated calcium sulphate beads. Two reviewers searched the literature in three online databases using the Cochrane methodology for systematic reviews. The search of databases yielded 182 articles. The studies without reported post-operative complications, mainly drainage outcomes, were excluded. After screening, seven articles were deemed suitable and selected. Out of the 1,112 cases identified, 43 joints developed wound drainage after calcium sulphate bead placement. This complication was resolved in all these cases by either conservative or operative approaches. The factors implicated in the development of wound drainage include the volume of the product used, procedural placement and host factors. The result of this systematic review shows that calcium sulphate products can be used for treatment and prophylaxis in prosthetic joints with a risk of post-procedural wound drainage. This risk, however, is lesser with the use of synthetic calcium sulphate products as compared with conventional calcium sulphate products.

The Risk of Iatrogenic Hypercalcemia in Patients Undergoing Calcium Sulphate Beads Implantation in Prosthetic Joint Surgery: A Systematic Review.

Calcium sulphate beads are increasingly being used in the management of prosthetic joint infections (PJI). Traditionally their use was limited to a void or dead space-filling combined with other additives such as Hydroxyapatite. Over the last decade, they have been developed to act more frequently as an antibiotics delivery system. Stimulan, a bio-absorbable form of Calcium sulfate, theoretically has an increased risk of hypercalcemia. Over the last few years, there have been published case reports which report it as an isolated cause of iatrogenic hypercalcemia. The sparsity of literature on this topic makes it difficult for surgeons to decide on the use of Calcium sulphate beads in patients with hypercalcemia predisposition in conditions like autoimmune disorders, sarcoidosis, malignancy, granulomatous diseases, heterotopic ossification, and hyperparathyroidism. The study was performed to assess the risk of hypercalcemia in patients after Calcium sulphate beads implantation in PJI. Two reviewers searched relevant literature in 3 online databases using cochrane methodology for systematic reviews. Studies reporting complications with the use of calcium sulphate beads in prosthetic joints were included. Studies reporting on less than five patients and studies reporting use in any other surgeries were excluded. The search of databases resulted in a total of 96 articles. After screening, a total of four articles were deemed suitable to be included in the analysis. A total of 1049 patients underwent calcium sulfate beads implantation, out of which 44 (4.2%) reported hypercalcemia with 41 (3.91%) transient in nature and 3 (0.28%) required management, including one with ICU admission. The result of this systematic review shows that calcium sulphate beads are safe and effective against PJI. There is a significant risk of transient hypercalcemia in susceptible patients and a low risk of symptomatic hypercalcemia.

The Outcome Of Surgical Management Of Chronic Pectoralis Major Ruptures In Weightlifters.

Pectoralis major repair is increasing in frequency due to the uptake of weight training. Chronic tendon injuries tend not to have as favourable outcomes. We report our outcome of chronic pectoralis major ruptures following surgical repair. Retrospective analysis of 8 patients who were weightlifters, treated for primary pectoralis major repair by one surgeon. Surgical repair was direct via suture anchors and one additionally required fascia lata graft due to tendon retraction. Outcome was assessed by comparing strength to the contralateral pectoralis muscle and the Oxford Shoulder Score. All patients were male with mean age of 36 years. Mean delay to surgery was 25.6 months. Mean followup was 19.6 months and mean Oxford Shoulder Score was 43.7. Six out of eight patients had full strength compared to the contralateral side. Complications included visible skin tethering not associated with weakness, stiffness associated with weakness and a seroma at fascia lata donor site. This is the largest documented study of Chronic Pectoralis Major repair showing excellent outcomes with repair, even if delayed.

Embolization coils migrating and being passed per rectum after embolization of a splenic artery pseudoaneurysm, "the migrating coil": a case report.

Acute or chronic blood loss from pseudoaneurysms of the splanchnic artery in chronic pancreatitis poses diagnostic and management challenges. Arteriographic examination offers both diagnostic and therapeutic options, with success rates of 76%-100% for both modalities. In cases of failure of embolization, repeat embolization is also an option. Surgical intervention is advocated for rebleeding and failure of embolization. Evidence-based guidelines regarding the optimal treatment modality for this condition are lacking. There has been a reported case of dislodgement of coil into the stomach through a gastropseudocystic fistula. We report the case of a migrating steel-wire coil through the gastrointestinal tract and splenic artery pseudoaneurysm. We highlight the potential complications of pseudoaneurysm and other available therapeutic management options.
