These injuries often result in acute weakness and have widely differing treatment options depending on the severity and the location of the injury within the upper extremity.

For zone II injuries, the tendons are often amenable to surgical repair with extension splinting for 6 weeks. Injuries at the central slip in zone III are often treated with closed extension splinting. In zone IV, these injuries are often treated similarly to those in zone II. Zone IV injuries without any extensor lag can often be treated nonoperatively with splinting; however, extension weakness is an indication for surgical repair. In zone V, the tendon is often substantial enough to hold sutures; however, because these injuries are often a result of a human bite wound, these are susceptible to more delayed repair or reconstruction following irrigation and débridement.

Despite advancements, most reconstruction techniques do not fully restore native MUCL stiffness. Internal brace augmentation to MUCL reconstruction presents a promising adjunct to traditional MUCL reconstruction, with recent studies showing improved biomechanical performance compared with MUCL reconstruction alone.

Various preoperative, intraoperative, and postoperative strategies aimed at reducing opioid consumption can be used by orthopaedic surgeons to help minimize this crisis. Preoperative screening tools can help identify patients at risk for prolonged opioid use, allowing for tailored interventions and counseling. Patient education initiatives, including multimedia presentations and handouts, have shown promising results in decreasing opioid consumption postoperatively. Intraoperatively, administering local and regional anesthesia in collaboration with anesthesia colleagues has proved effective for minimizing postoperative pain and opioid requirements. Postoperatively, alternative therapies such as acetaminophen, NSAIDs, and cryotherapy offer viable options for pain management while reducing reliance on opioids. In addition, the prudent prescribing of opioids, based on patient needs and expectations, coupled with refill options, helps minimize excess opioid supply and potential diversion. Orthopaedic surgeons are urged to embrace a multimodal approach to pain management and decrease opioids prescription while integrating these various strategies to optimize outcomes while mitigating the risks associated with opioid use.</p>","PeriodicalId":73392,"journal":{"name":"Instructional course lectures","volume":"74 ","pages":"313-322"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The guiding principles of trauma care are almost exclusively based on blunt trauma, and the management principles do not always translate. Ballistic long bone fractures, particularly of the lower extremity, can often be managed with similar principles, although the injury pattern can make restoration of anatomic alignment a challenge. Some data suggest that patients with ballistic arthrotomies can be safely treated with medical management and antibiotic therapy alone; however, gross contamination can be encountered, and this decision is at the surgeon's discretion. Retained ballistic fragments may result in intra-articular changes and elevated lead levels over time, warranting consideration for surgical excision. Ballistic injuries to the hand and wrist are often present with concomitant soft-tissue injury, including nerve and tendon injuries. Providing stable bony fixation while also facilitating early motion for rehabilitation is a difficult balance to reach. In addition, the management of ballistic nerve injuries is controversial, as many injuries are not simply neurapraxic, and either early exploration or evaluation with ultrasonographic imaging may help detect injuries for which repair or grafting can be considered. Last, ballistic trauma can have mental health implications for patients and families and even contribute to the burnout epidemic demonstrated in health care professionals.</p>","PeriodicalId":73392,"journal":{"name":"Instructional course lectures","volume":"74 ","pages":"379-392"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
