There is ongoing controversy regarding the best treatment of fingertip amputations, conservative treatment with secondary healing or surgical intervention. Healing by secondary intention has been proven to offer satisfactory recovery and function. More extensive wounds are treated surgically. However, even in Allen III and IV amputations, there is a lack of evidence to support enhanced healing and function of fingertips after surgical treatment compared to conservative management. Regarding fingertip amputations after animal bites, thorough debridement is the preferred treatment due to various micro-organisms, while there is no consensus about the primary closure of the wound. Inclusion cri-teria are complete amputations even with bone involvement at all levels. Exclusion criteria are skeletonized distal phalangeal bone, not surrounded by soft tissues, joint involvement and exposed tendon. It offers complete regeneration of the fingertip without signs of infection, even in animal bites wounds. There are few reports in the literature regarding the semi-occlusive dressing for treating fingertip amputations-only one report uses this technique after an animal bite in a two-year-old girl. In this case report, an Allen III fingertip amputation caused by a dog bite in a 64-year-old female was managed successfully using the semi-occlusive dressing technique. At the final follow up three months after the injury, the aesthetic results were satisfactory. The fingertip with the nail complex was almost normal with no nail hook deformity. The pad skin regenerated with no signs of infection. The functional results were excellent, with no joint stiffness or disability. The sensibility was satisfactory with two-point discrimination of 4 mm, and there was no tenderness, cold intolerance, or neuroma. The patient was satisfied and able to participate in all daily activities. The semi-occlusive dressing technique is an alternative treatment option for Allen III fingertip amputations after animal bites. It promotes regenerative healing, and despite bacterial colonization, no infection has been reported.There is ongoing controversy regarding the best treatment of fingertip amputations, conservative treatment with secondary healing or surgical intervention.

Introduction: Knee arthrodesis is a limb salvage intervention for persistent periprosthetic joint infection (PJI) when revision total knee arthroplasty fails. Conventional arthrodesis techniques are associated with the increased rate of complications, especially in patients with extensive bone loss and extensor tendon deficiency. Methods: Eight patients with a modular silver-coated arthrodesis implant after failed exchange arthroplasty for infection, were retrospectively reviewed. All patients had significant bone loss, while 5 displayed extensor tendon deficiency. Survivorship, complications, leg length discrepancy, median Visual Analogue Scale (VAS) and Oxford Knee score (OKS) were evaluated. Results: The median follow up was 32 months (range 24–59 months). The survivorship rate of the prosthesis was 86% during the minimum time of follow up of 24 months. In one patient recurrence of the infection was observed and above-knee amputation was performed. The median postoperative leg length discrepancy was 2.07 ± 0.67 cm. Patients were able to ambulate with mild or no pain. The median VAS and OKS was 2.14 ± 0.9 and 34.7 ± 9.3, respectively. Conclusions: The results of our study demonstrated that knee arthrodesis with a silver coated arthrodesis implant, performed for persistent PJI in patients with significant bone loss and extensor tendon deficit, provided a stable construct, allowed eradication of infection and was associated with good functional outcome.
