External fixation is a powerful tool in the armamentarium of the active orthopaedic surgeon. The upper extremity, however, poses unique challenges in the techniques of external fixation because of the smaller soft-tissue envelope and the proximity of neurovascular structures, which may be entrapped in fracture fragments or traversing in line with pin trajectories. This review article summarizes the indications, techniques, clinical outcomes, and complications of external fixation of the upper extremity in the setting of proximal humerus, humeral shaft, distal humerus, elbow, forearm, and distal radius fractures.

BACKGROUND/UNASSIGNED:The posterolateral approach to the ankle allows for reduction and fixation of the posterior and lateral malleoli through the same surgical incision. This can be accomplished via 1 or 2 surgical "windows." The purpose of this study is to compare outcomes including wound complications following direct fixation of unstable rotational ankle fracture through the posterolateral approach using either 1 or 2 surgical windows. METHODS/UNASSIGNED:One hundred sixty-four patients with bi- or trimalleolar ankle fractures treated using the single-window posterolateral approach (between the peroneal tendons and the flexor hallucis longus [FHL]) or the 2-window technique (between the peroneal tendons and the FHL for posterior malleolus fixation; lateral to the peroneal tendons for fibula fixation) were reviewed for demographics, radiographic details, and clinical outcomes. We were able to review these 164 at the 3-month follow-up and a subset of 104 at a minimum of 12-month follow-up. RESULTS/UNASSIGNED: = .021). We did not find a significant difference in nerve complications for these 2 cohorts. CONCLUSION/UNASSIGNED:In our study, we found the single-window posterolateral approach to be associated with fewer wound complications and better postoperative range of ankle motion when compared to the 2-window approach. LEVEL OF EVIDENCE/UNASSIGNED:Level III, retrospective cohort study.

PURPOSE/OBJECTIVE:To determine if the DTS decreases radiation exposure (primary outcome measure), fluoroscopy time (secondary outcome measure), and time to distal screw placement (secondary outcome measure) compared to the freehand "perfect circles" method when used for locking of cephalomedullary nails in the treatment of femur fractures METHODS: Fifty-eight patients with hip or femoral shaft fractures that were treated with a long cephalomedullary nail were enrolled in this study. Cohorts were determined based on the method of distal interlocking screw placement into either the "Perfect Circles" or "Distal Targeting" cohort. Time from cephalad screw placement to placement of final distal interlocking screw (seconds), radiation exposure (mGy), and fluoroscopy time (seconds) were compared between groups. Hospital quality measures were compared between cohorts. RESULTS:Use of the DTS resulted in 77% (4.3x) lower radiation exposure (p < 0.001), 64% (2.7x) lower fluoroscopy time (p < 0.001), and 60% (1.7x) lower intraoperative time from end of cephalad screw placement to end of distal interlocking screw placement (p < 0.001) compared to the freehand "perfect circles" method. There was no difference in 30-day or 90-day complication rates between cohorts. CONCLUSION/CONCLUSIONS:The Stryker Gamma3® Distal Targeting System is a safe, effective and efficient alternative to the freehand "perfect circles" method.

OBJECTIVES/OBJECTIVE:To examine the efficacy of regional anesthesia with sedation only for a variety of hip fractures using the newly described lateral femoral cutaneous with over the hip Block (LOH Block). DESIGN/METHODS:Retrospective. SETTING/METHODS:Level-I Trauma CenterPatients/Participants: 40 patients who presented between 11/2021 and 02/2022 for fixation of OTA/AO 31.A1-3 and 31.B1-3 fractures. Matched cohorts of 40 patients who received general anesthesia and 40 patients who received spinal anesthesia for hip fracture fixation were also used. INTERVENTION/METHODS:Operative fixation under LOH block and sedation only. The LOH block is a regional hip analgesic that targets the lateral femoral cutaneous nerve, articular branches of femoral nerve (FN) and accessory obturator nerve (AON). MAIN OUTCOME MEASUREMENTS/METHODS:Demographics, intraoperative characteristics, anesthesia-related complications, hospital quality metrics, and short-term mortality and reoperation rates. RESULTS:A total of 120 patients (40 each: general, spinal, LOH block) were compared. The cohorts were similar in age, race, BMI, gender, CCI, trauma risk score, ambulatory status at baseline, fracture type, and surgical fixation technique performed. Physiologic parameters during surgery were more stable in the LOH block group (p<0.05). Total OR time and anesthesia time were shortest for the LOH block cohort (p<0.05). Patients in the LOH block cohort also had lower post-operative pain scores (p<0.05). Length of hospital stay was shortest for patients in the LOH block cohort (p<0.05), and at time of discharge, patients in the LOH block cohort ambulated the furthest (p<0.05). No differences were found in regards to anesthesia-related complications, palliative care consults, major and minor hospital complications, discharge disposition, reoperation and readmission rates, and mortality rates. CONCLUSIONS:The LOH block is safe and effective anesthesia for the treatment of all types of hip fractures in the elderly requiring surgery. In addition, this block may decrease post-operative pain and length of hospital stay, and also allow for greater ambulation in the early post-operative period for hip fracture patients.

OBJECTIVES/OBJECTIVE:To compare short term functional outcomes, reduction loss, and rates of surgery for distal radius fractures initially immobilized with a traditional sugartong splint vs clamshell splint freeing the elbow. DESIGN/METHODS:Prospective Randomized Trial. SETTING/METHODS:Level 1 Trauma Center. PATIENTS/METHODS:Eighty-nine consecutive patients sustaining distal radius fractures were enrolled between 2018 and 2020. Short term first follow up (1-2 weeks) radiographic parameters and 6 weeks for functional questionnaires were established to assess initial outcomes. MAIN OUTCOME MEASURES/METHODS:Reduction loss based on radiographic criteria, rate of surgery, short term patient functional outcome using the DASH score. RESULTS:There were no differences noted in DASH scores (p-value=0.8) or loss of reduction (p-value=0.69) and splint type was not correlated with likelihood to have surgery (p=0.22). A binomial regression model demonstrated splint type was not a significant predictor variable of loss of fracture reduction in the regression model. CONCLUSIONS:These results suggest both sugartong splint and clamshell splint construct are acceptable options in the acute management of distal radius fractures. LEVEL OF EVIDENCE/METHODS:Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

OBJECTIVE:To assess the effectiveness of a multimodal analgesic regimen containing "safer" opioid and non-narcotic pain medications in decreasing opioid prescriptions following surgical fixation in orthopedic trauma. DESIGN/METHODS:Retrospective cohort study. SETTING/METHODS:One urban, academic medical center. SUBJECTS/METHODS:Traumatic fracture patients from 2018 (848) and 2019 (931). METHODS:In 2019 our orthopedic trauma division began a standardized protocol of post-operative pain medications that included: 50 mg of tramadol four times daily, 15 mg of meloxicam once daily, 200 mg gabapentin twice daily, and 1 g of acetaminophen every 6 hours as needed. This multimodal regimen was dubbed the "Lopioid" protocol. We compared this protocol to all patients from the prior year who followed a standard protocol that included Schedule II narcotics. RESULTS:Greater mean MME were prescribed at discharge from fracture surgery under the standard protocol compared to the Lopioid protocol (252.3 vs 150.0; p < 0.001) and there was a difference in the type of opioid medication prescribed (p < 0.001). There was a difference in the number of refills filled for patients discharged with opioids after surgical treatment between standard and Lopioid cohorts (0.31 vs 0.21; p = 0.002). There was no difference in the types of medication-related complications (p = 0.710) or the need for formal pain management consults (p = 0.199), but patients in the Lopioid cohort had lower pain scores at discharge (2.2 vs 2.7; p = 0.001). CONCLUSIONS:The Lopioid protocol was effective in decreasing the amount of Schedule II narcotics prescribed at discharge and the number of opioid refills following orthopedic surgery for fractures.

ABSTRACT/UNASSIGNED:Globally, the burden of musculoskeletal conditions continues to rise, disproportionately affecting low and middle-income countries (LMICs). The ability to meet these orthopaedic surgical care demands remains a challenge. To help address these issues, many orthopaedic surgeons seek opportunities to provide humanitarian assistance to the populations in need. While many global orthopaedic initiatives are well-intentioned and can offer short-term benefits to the local communities, it is essential to emphasize training and the integration of local surgeon-leaders. The commitment to developing educational and investigative capacity, as well as fostering sustainable, mutually beneficial partnerships in low-resource settings, is critical. To this end, global health organizations, such as the Consortium of Orthopaedic Academic Traumatologists (COACT), work to promote and ensure the lasting sustainability of musculoskeletal trauma care worldwide. This article describes global orthopaedic efforts that can effectively address musculoskeletal care through an examination of 5 domains: clinical care, clinical research, surgical education, disaster response, and advocacy.

Foot compartment syndrome is an uncommon condition that should be recognized by all orthopedic surgeons. The clinical presentation is often less clear than other limb compartment syndromes and requires high clinical suspicion with a low threshold for direct measurement of compartment pressure. Controversy exists regarding the number of anatomic compartments and the most effective treatment. Both acute surgical intervention and delayed management can result in significant morbidity and long-term sequelae.

Although distal radius fractures are quite common, bilateral distal radius fractures seldomly occur. Due to this, treatment is primarily based on surgeon experience with unilateral fractures, however bi- lateral fractures add a level of complexity : loss of functional independence. The purpose of this study was to examine a cohort of patients with bilateral distal radius fractures to identify differences in demographics, mechanism of injury, and outcomes to further our understanding of these rare injuries. 23 patients were identified retrospectively over a 5-year period that met inclusion criteria. The medical records were reviewed with multiple demographic and clinical parameters recorded and analyzed. Males were more likely to sustain high-energy mechanisms (80% vs. 53%). Patients <50 years old were more likely to sustain high-energy mechanisms (90% vs. 46%) and were more likely to be treated operatively (80% vs. 62%). The most commonly associated injury was a head injury (30%). All patients treated non-operatively reported minimal/no pain upon final follow-up where 57% of patients treated operatively noted regular pain. 75% of patients with medical comorbidities had minimal/no pain upon final follow- up. Conclusions : Patients with bilateral fractures were more likely to be younger males who suffered from higher energy mechanisms. Age was a critical factor in determining treatment strategy. Rates of associated head injuries were elevated, which is an important factor for the clinician to keep in mind when treating this population. As we further our understanding of this unique population, we can improve our treatment approaches and subsequently attain better outcomes.
