Case: A 44-year-old man with osteogenesis imperfecta presented with multiple debilitating musculoskeletal deformities. Bi-level osteotomies, assisted by 3-dimensional (3D)-printed patient-specific cutting guides, were performed to correct extraarticular valgus and procurvatum tibial deformities. Concomitant computer-navigated total knee arthroplasty was performed to restore neutral mechanical alignment. Postoperative x-ray showed good correction of deformities, and 1 year postoperatively, the patient is able to walk unaided with significant resolution of knee pain. Conclusion: 3D-printed osteotomy guides and computer navigation can be instrumental in procedures requiring a high degree of precision. With sufficient training, modern orthopaedic technologies can be implemented by surgeons themselves and combined to facilitate precise and personalized management of challenging conditions.

Case: We describe 2 patients who sustained a periprosthetic humeral fracture with a loosened long-stemmed Coonrad-Morrey total elbow prosthesis. As noted in the literature, the success rate for a major revision with use of strut grafts is around 70%; therefore, both cases were managed without revision of the prosthesis. A submuscular locking plate was placed following typical fracture fixation principles. Screws that interfered with the humeral stem and the distal flange stabilized both the distal fragment and the humeral stem. Conclusion: At 2 years postoperatively, both fractures had healed, with increased endosteal bone stock. In each case, the prosthesis was successfully salvaged, and radiographic reconstitution of the implant-bone interface was noted after 2 years. [ABSTRACT FROM AUTHOR]

The article presents two case studies of atypical subtrochanteric fractures in patients who had undergone long-term bisphosphonate therapy. The first patient had taken alendronate for osteoporosis and was presented to the hospital after a minor twisting injury to the left leg. The second patient was presented to the hospital due to a low-energy trauma after three years of alendronate therapy for osteoporosis.

Background: The analgesic effect of adding liposomal bupivacaine to standard bupivacaine in supraclavicular brachial plexus block is not known. We hypothesized that addition of liposomal bupivacaine would reduce acute postoperative pain compared to standard bupivacaine alone., Methods: A randomized controlled trial was conducted. Patients and outcome assessors were blinded. Eighty patients undergoing distal radial fracture fixation under regional anesthesia with supraclavicular brachial plexus block were randomized into two groups. The liposomal bupivacaine (LB-BPB) group received 10ml of 0.5% plain bupivacaine immediately followed by 10ml of 1.33% liposomal bupivacaine (n=40). The standard bupivacaine (S-BPB) group received 20ml of 0.5% plain bupivacaine (n=40). The primary outcome was weighted area under curve (AUC) numerical rating scale (NRS) pain score at rest over the first 48 hours after surgery. Secondary outcomes included AUC scores for pain with movement, overall benefit with analgesia score (OBAS) and other functional scores., Results: For the primary outcome, LB-BPB group was associated with statistically significantly lower AUC pain score at rest (0.6 vs 1.4, p-value < 0.001) in the first 48 hours. Of the secondary outcomes, no difference between treatment groups reached statistical significance with the exception of AUC score for pain with movement (2.3 vs 3.7, adjusted p-value < 0.001) and OBAS (1.1 vs 1.7, adjusted p-value = 0.020) in the first 48 hours, as well as NRS pain score at rest (0.5 vs 1.9, adjusted p-value < 0.001) and with movement (2.7 vs 4.9, adjusted p-value < 0.001) on postoperative day (POD) 1. Differences in NRS pain scores on POD2, POD3 and POD4 did not reach the level of statistical significance. There were no statistically significant differences in sensory function., Conclusion: Liposomal bupivacaine given via supraclavicular brachial plexus block reduced pain at rest in the early postoperative period., Competing Interests: Conflict of Interest: The authors declare no competing interests., (Copyright © 2024 The Author(s).
