PURPOSE: To compare patient-reported outcomes, functional outcomes, radiographic alignment, and complications of volar versus dorsal corrective osteotomies as the treatment for symptomatic distal radius malunions.

METHODS: We performed a retrospective review of all patients who underwent a distal radius corrective osteotomy with either a volar or dorsal approach and plating at 1 of 3 institutions between 2005 and 2017. Demographic data, type of surgical treatment, and radiographs were examined. Outcomes were Quick-Disabilities of the Arm, Shoulder, and Hand (QuickDASH) function scores and radius union scoring system as well as major and minor complications.

RESULTS: We included 53 cases (37 volar osteotomies and 16 dorsal osteotomies). Postoperative follow-up from the time of surgery to last QuickDASH score was 84.6 months (range, 12-169.4 months). Compared with the dorsal osteotomy group, the volar osteotomy group demonstrated a better postoperative flexion-extension arc (94.9° vs 72.9°, respectively), pronation-supination arc (146.2° vs 124.9°, respectively), and last QuickDASH scores (6.65 vs 12.87), respectively. Radiographically, there was no difference noted in radial height, radial inclination, or volar tilt in the immediate postoperative and last radiographs. There was a higher rate of complications in the dorsal osteotomy group (8 cases [50% of patients]) compared with the volar osteotomy group (7 cases [18.9% of patients]), including a higher rate of hardware removal.

CONCLUSIONS: For patients with symptomatic malunions of the distal radius, the volar and dorsal approaches both resulted in improvement in QuickDASH scores and range of motion. Volar plating resulted in slightly better QuickDASH scores and fewer complications compared with dorsal plating.

TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: Osseous tumors of the shoulder girdle occur most frequently in the proximal humerus, scapula and clavicle. Prior studies have determined that tumors occurring in the scapula have a higher risk of malignancy, but few have looked exclusively at tumors of this site to describe incidence, clinical features and potential predictors of malignancy. As imaging technologies for diagnosis have improved, it is important to re-evaluate if patterns of incidence have changed and if new imaging findings could potentially be predictors of malignancy.

METHODS: This retrospective analysis identified 173 patients from a pediatric and an adult hospital between 1990 and 2015. All patients with tumors of the scapula either of bony origin or with bony invasion were included. Diagnosis, tumor location, and patient demographics were collected. Bivariate and logistic regression analyses were performed to identify potential predictors of malignancy.

RESULTS: Chondrosarcoma and osteochondroma were the most common malignant and benign tumors, respectively. Benign tumors were more prevalent in the pediatric population. Tumors occurred most frequently in the body of the scapula. Risk for malignancy increased with age (OR 1.09, 95% CI 1.05-1.12), tumors invading multiple sites (OR 10.85, 95% CI 2.37-49.72) and tumors that were lucent (OR 7.02, 95% CI 1.14-43.21) or had a mixed radiographic appearance (OR 11.47, 95% CI 1.36-99.65).

CONCLUSIONS: Including neoplasia in the differential diagnosis for shoulder complaints is important because the scapula is a site of increased risk of malignancy. Patterns of incidence and prevalence have not changed in the last years with the use of more advance techniques of imaging studies. Older age, lucent or mixed imaging, and tumors that span multiple sites of the scapula were found to be predictors of malignancy. Additional cross-sectional anatomy studies may be warranted for further evaluation in patients presenting with these characteristics given the higher concern for malignant disease.

LEVEL OF EVIDENCE: Level IV, Prognostic Study.

PURPOSE: A paucity of evidence exists regarding the optimal treatment of open fractures of the distal radius. The purpose of this study was to compare short-term complication rates between various treatment options following open fractures of the distal radius.

METHODS: We performed a retrospective review of all open fractures of the distal radius at a single level 1 trauma center over a 10-year period. The primary outcome measure was the number of minor and major complications. Demographic and clinical characteristics of patients across treatment and outcome groups were compared and models were used to describe the relationships between outcome and treatment.

RESULTS: Ninety patients met the inclusion criteria for evaluation. An even distribution between high-energy (n = 45) and low-energy (n = 45) injuries was seen with 61 fractures Gustilo I (67%), 19 Gustilo II (22%), and 10 Gustilo III (11%). The majority of fractures were intra-articular (n = 48 AO type C vs n = 42 AO type A/B). Fractures were treated with immediate open reduction internal fixation (ORIF) in 67 cases (74%), external fixation in 12 (13%), initial external fixation followed by ORIF at a later time in 8 (9%), or closed reduction and percutaneous pinning in 3 (4%). We observed 33 complications (37%) of which 24 were major and 9 minor. Mechanism of injury and type of treatment were the only variables shown to correlate with an increased rate of complications.

CONCLUSIONS: We conclude that open fractures of the distal radius treated by immediate ORIF at the time of index debridement can result in satisfactory outcomes compared with other forms of treatment.

TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: Surgical fixation of syndesmotic instability using quadricortical fixation, whether screws or suture-button devices, places structures on the medial side of the tibia at iatrogenic risk. This study aims to radiographically map the anatomic course of structures on the medial aspect of the distal tibia to be able to at-risk zones (ARZs) for syndesmotic fixation.

METHODS: Eighteen fresh-frozen cadaveric ankle specimens were dissected. The saphenous neurovascular bundle (SNVB) and the posterior tibial tendon (PTT) were identified and marked with copper wiring. Standardized and calibrated lateral radiographs of the distal tibia and fibula were analyzed using a grid system consisting of 3 columnar zones from anterior to posterior and five 1-cm rows to chart the anatomic course of the SNVB and the PTT.

RESULTS: The SNVB was located in the more anterior zones (1, 2, or anterior to Zone 1) in 97.3% of specimens. The SNVB traversed from posterior to anterior as it descended proximal to distal. The PTT was found in Zone 3 (most posterior zone) for all specimens. The PTT was noted to pass behind (radiographically overlap) the tibia in 83.3% (15 of 18) of specimens between 1 and 3 cm above the tibiotalar joint.

CONCLUSIONS: Placement of quadricortical syndesmotic fixation places structures on the medial ankle at risk. The SNVB is at considerable risk along the anterior course of the distal tibial while the PTT is only at risk in zone 3 at the distal extent of the tibia.

OBJECTIVE: Although the number of female medical school graduates has dramatically increased over the last decades, Orthopaedic surgery continues to struggle in attracting women and under-represented minorities to the field. Potential barriers include limited exposure during medical school and the scarcity of female mentors. We hypothesized that a structured, low-cost, workshop for medical students allowing exposure to orthopaedic surgery would increase students' interest in the field. Our primary outcome was the perceived satisfaction with the program and the number of students who subsequently expressed an interest in pursuing a career in orthopaedic surgery. Our secondary outcome was the number of student participants who subsequently matched in orthopaedic surgery.

DESIGN: Combining female faculty from surrounding hospitals, we developed a free half-day program including skills workshops and panel discussions for women medical students in the region. Participants were asked to complete an anonymous survey grading their satisfaction with the utility of the information presented, the comfort level in interacting with faculty and how the experience may have impacted their potential interest in orthopaedic surgery. Eligible participants were contacted by email to determine their ultimate career choices and match results. Furthermore, participants were followed over time to determine how many chose and matched into an orthopaedic surgery residency.

SETTING: The workshop took place in Boston at the Harvard Medical School affiliated hospitals.

PARTICIPANTS: Student participants were invited from all New England allopathic and osteopathic medical schools. Faculty participants included staff, residents and fellows from the Harvard Combined Orthopaedic Residency Program.

RESULTS: Over 3 years, 155 female medical students participated in the program and 97% found it useful. Among 59 students who have since become eligible for the match, 22 matched into an orthopaedic surgery residency. Eight of 36 (22%) match eligible first and second year participants matched in orthopaedic surgery while 14 of 23 (61%) match eligible third and fourth year student attendees successfully matched in orthopaedic surgery programs.

CONCLUSIONS: Taking advantage of local resources, we demonstrated that outreach is effective in enhancing students' interest in the field. We encourage as many programs as possible to consider similar initiatives.

BACKGROUND: Talus fractures are severe injuries typically occurring after high-energy trauma. As a result, associated injuries to different anatomic sites and organ systems occur with high frequency. The objective of this study was to determine what injuries occur with high incidence in patients presenting with major fractures of the talus and to identify clinical injury patterns that may warrant special attention in these patients.

METHODS: We performed a retrospective review of patients presenting to 3 level 1 trauma centers with fractures of the talar neck, body, or head over a 14-year period. Patient charts were reviewed for associated orthopedic and nonorthopedic injuries identified during the initial patient encounter and hospitalization.

RESULTS: In total, 262 fractures in 258 unique patients met criteria for inclusion. Overall, 33.3% of talus fractures occurred in isolation. One or more associated injuries were identified in the remainder of cases (66.7%). The incidence of associated injuries was similar across fracture patterns. Mean total number of injuries per patient was 2.2 (range, 0-15). The ipsilateral foot was the most frequent site of associated orthopedic injury. Noncontiguous injuries occurred in 36% of cases. Lumbar spine injury occurred in 10.5% of cases. Lower extremity vascular injury was uncommon but bore significant association with open talus fractures.

CONCLUSION: Talus fractures are commonly associated with injuries to different anatomic sites and organ systems. A similar rate of lumbar spine trauma may occur with major talus fractures as has been historically associated with calcaneal fractures. Thorough evaluation and a high index of suspicion are necessary when evaluating patients with major fractures of the talus to avoid missing concomitant injuries.

LEVEL OF EVIDENCE: Level IV, retrospective case series.

Spinal surgery has been revolutionized by advances in instrumentation, bone graft substitutes, and perioperative care. Extensive dissection, creation of large areas of dead space, and the use of instrumentation in compromised patients, however, predisposes to high rates of wound complications. Postoperative wound complications in patients undergoing complex spinal surgery can have devastating sequelae, including hardware exposure, meningitis, and unplanned reoperation. Recognition of high-risk patients and prediction of wound closure difficulties, combined with preemptive reconstructive surgical strategies may prevent complications. The purpose of this review is to discuss the principles of spine wound management and provide a synopsis of the soft tissue reconstructive strategies utilized in spinal surgery. We review the senior author's preferred reconstructive algorithm for the management of these complex wounds, in addition to outcomes data relating to the timing of reconstructive surgery.

The underlying theme throughout this series of studies authored by the Multicenter anterior cruciate ligament (ACL) Revision Study consortium has been to determine the modifiable predictors or risk factors of long-term outcomes of revision ACL reconstruction. The observational studies described and summarized in the manuscript are both clinically relevant and of great interest in finding out the long-term consequences of the intervention and its relationship to the original injury. The successful completion of these studies has important implications for both therapy and future clinical trials. The identification of modifiable risk factors will play an important role in secondary prevention, while the identification of nonmodifiable risk factors will aid us in counseling our patients and making surgical decisions. Thus, we expect a profound clinical impact on patients' care. More importantly, this project represents an important step forward in bringing evidence to bear in clinical decision making in orthopedic surgery.
