The Effect of Greater Area Deprivation and Medicaid Insurance Status on Timing of Care and Rate of Reinjury After Anterior Cruciate Ligament Reconstruction.

Background: Lower socioeconomic status and public insurance lead to a longer delay to surgery and a higher likelihood of concomitant pathology before undergoing anterior cruciate ligament reconstruction (ACLR). However, few studies have examined the influence of community deprivation on ACLR timing and outcomes. Purpose/Hypothesis: The primary aim of this study was to define the effect of the area deprivation index (ADI) and insurance classification on access to orthopaedic care after an ACL rupture, and the secondary aim was to determine whether these variables were associated with a second ACL injury after primary ACLR. It was hypothesized that patients with a greater national ADI percentile and Medicaid insurance would experience longer delays to care and an increased risk of reinjury after ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective study was performed to evaluate patients undergoing primary ACLR between 2016 and 2019. The national ADI percentile was obtained utilizing the Neighborhood Atlas website. The relationship between national ADI percentile and care characteristics (eg, time to specialized care) was investigated using the Spearman rho correlation coefficient (r). The association between patient and care characteristics and second ACL injury after the index procedure (ie, graft rerupture or contralateral ACL rupture) was investigated using binary logistic regression. Results: A total of 197 patients met the inclusion criteria. Longer times from injury to surgery (r = 0.238; P < .001) and from specialized care to surgery (r = 0.217; P = .002) were associated with a greater national ADI percentile. The second injury group reported significantly greater national ADI (P = .026) and included a greater percentage of patients with Medicaid insurance (31.3%) compared with the no second injury group. Patients experienced 5.1% greater odds of a second ACL injury for each additional month between evaluation and surgery. Conclusion: Greater national ADI percentile and Medicaid insurance status were associated with adverse ACLR timing and outcomes. Patients with a greater national ADI percentile took significantly longer to obtain surgery after ACL injury. Those who sustained a second ACL injury after ACLR had an overall higher mean national ADI percentile and included a greater proportion of patients with Medicaid compared with those who did not sustain a second ACL injury. Future studies should critically investigate the underlying factors of these associations to reach equity in orthopaedic care.

Successfully Treated Upper-Extremity Necrotizing Fasciitis Caused by Photobacterium damselae.

Necrotizing fasciitis is a soft-tissue infection associated with significant morbidity and mortality. The bacteria most associated with necrotizing fasciitis include Streptococcus pyogenes (group A), Clostridium species, Streptococcus species, and Staphylococcus species. Photobacterium damselae (P. damselae), formerly known as Vibrio damselae, is a halophilic, gram-negative bacillus known to infect marine organisms in warm coastal waters. Necrotizing fasciitis associated with P. damselae has been reported to have higher rates of serious complications and mortality because of an atypical presentation and a rapidly progressive course. This report presents a case of successfully treated P. damselae necrotizing fasciitis of the upper extremity and the nuances of management that led to a favorable outcome in which the patient was discharged for home without complications.

Functional and Disability Assessment Among Hispanics With Zone 2 Flexor Tendon Injuries: Comparative Study Between Flexor Digitorum Superficialis Repair and Flexor Digitorum Superficialis Excision.

INTRODUCTION: Flexor tendon lacerations in zone II have been reported to be the most complicated of all tendon injuries. Currently, there is no consensus on treatment in surgical management for patients with flexor tendon laceration of flexor digitorum profundus and flexor digitorum superficialis (FDS). The aim of this study was to evaluate whether the repair of FDS tendons provided superior functional outcomes compared with FDS excision in Hispanic patients. METHODS: Total active motion, original Strickland criteria, and the disability of arm shoulder and hand questionnaire were provided postoperatively at 3 and 6 months to all consecutive Hispanic patients who underwent zone II flexor tendon repair. The cohort was divided into two groups, those who underwent FDS repair and those underwent FDS excision. RESULTS: Functional and disability outcome analysis showed a notable improvement with FDS repair using total active motion, Strickland criteria, and disability of arm shoulder and hand score at the 3 months postoperative interval. No statistical differences were identified regarding functional and disability outcomes at the 6-month evaluation between both groups. CONCLUSIONS: Among Hispanics, the FDS-repaired group had similar functional and disability outcomes at their 6 months postoperative evaluation compared with the FDS-excised group. Increased awareness for tendon rerupture during the initial 3 months of index surgery is recommended for FDS-excised patients.

Practice Variation Among Hispanic American Orthopedic Surgeons in the Management of Geriatric Distal Radius Fracture.

INTRODUCTION: There is a controversy in the management of distal radius fractures (DRF) and its criteria for surgical intervention on geriatric patients. The American Academy of Orthopedic Surgeons (AAOS) developed evidence-based guidelines for treatment of DRF. The aim of this study was to evaluate the current practice of Hispanic orthopedic surgeons in the management of geriatric DRF and examine their adherence to AAOS guidelines based on years of surgical experience. MATERIAL & METHODS: A survey was emailed to all orthopedic surgeons who live in Puerto Rico and treated DRF in their daily practice. Responses concerning demographic, management and clinical scenarios were evaluated. For each clinical scenario, treatment of choice was selected with the same fracture in a geriatric and young adult patient. Comparison between years of surgical experience and adherence to the AAOS guidelines was performed. RESULTS: A total of 65 surgeons responded the survey with 65% having >15 years in practice. A high consensus with AAOS guidelines for DRF was found. Use of preoperative radiographs was reported in all respondents, with an additional 12% routine use of preoperative computed tomography scans. Seventy-seven percent of respondents did not allow any range of motion (ROM) at immediate postoperative period, while 23% allowed active or passive ROM. Use of postoperative therapy was reported in 72.3%. Correlation between years of surgical experience showed a higher use of Vitamin C postoperatively for prophylaxis of Complex Regional Pain Syndrome among surgeons <15 years (P = 0.01). A general consensus trend toward operative fixation was noted among geriatric and young adult patients with the same fracture type in all clinical scenarios. DISCUSSION AND CONCLUSIONS: This survey demonstrates a practice variation toward surgical management of geriatric DRF among Hispanic orthopedic surgeons; despite their compliance with the AAOS AUC guidelines. The geriatric DRF management does not vary significantly among years of surgical experience.

The effect of the anabolic steroid, nandrolone, in conditioned place preference and D1 dopamine receptor expression in adolescent and adult mice.

Adolescents and adults engage in anabolic-androgenic steroid (AAS) misuse seeking their anabolic effects, even though later on, many could develop neuropsychological dependence. Previously, we have shown that nandrolone induces conditioned place preference (CPP) in adult male mice. However, whether nandrolone induces CPP during adolescence remains unknown. In this study, the CPP test was used to determine the rewarding properties of nandrolone (7.5 mg/kg) in adolescent mice. In addition, since D1 dopamine receptors (D1DR) are critical for reward-related processes, the effect of nandrolone on the expression of D1DR in the nucleus accumbens (NAc) was investigated by Western blot analysis. Similar to our previous results, nandrolone induced CPP in adults. However, in adolescents, nandrolone failed to produce place preference. At the molecular level, nandrolone decreased D1DR expression in the NAc only in adult mice. Our data suggest that nandrolone may not be rewarding in adolescents at least during short-term use. The lack of nandrolone rewarding effects in adolescents may be due, in part to differences in D1DR expression during development.
