BACKGROUND Posttraumatic osteoarthritis (PTOA) is a common and early sequela of tibial pilon fractures resulting in substantial long-term disability. New approaches are needed to objectively and reliably quantify early disease progression in order to critically assess the impact of interventions aimed at preventing or mitigating PTOA. Weight-bearing computed tomography (WBCT) scans provide a means for measuring joint space while the ankle is in a loaded, functional position. We assessed the interrater and intrarater reliability of a standardized, regional method to quantify joint-space loss following tibial pilon fracture compared with the uninjured contralateral ankle. METHODS We prospectively enrolled 20 patients with intra-articular tibial pilon fractures that were surgically treated at 1 of 2 level-I trauma centers. Six months after injury, bilateral ankle WBCT scans were obtained. Joint space was measured by 4 reviewers at 9 discrete regions of the tibiotalar articulation on sagittal images. Measurements were repeated by reviewers 2 weeks later. To characterize the measurement method, interrater correlation coefficient estimates and test-retest reproducibility were calculated. RESULTS The mean tibiotalar joint space was 21% less in the injured ankles compared with the contralateral uninjured ankles (p less then 0.0001). The middle-lateral and middle-central regions of the joint demonstrated the greatest decrease in joint space between injured and uninured ankles. The interrater correlation coefficient of the measurement technique was 0.88, and the test-retest reproducibility was 0.80, indicating good reliability and reproducibility of the method. CONCLUSIONS We developed a simple, standardized, and reliable technique to quantify tibiotalar joint space following tibial pilon fracture on WBCT. Significant loss of joint space is seen 6 months after the injury. This tool can be used to longitudinally quantify loss of joint space following pilon fracture and assess the impact of interventions to reduce PTOA.BACKGROUND Male patients undergoing total joint arthroplasty have a higher risk of periprosthetic joint infection (PJI) compared with female patients. The exact reason for this finding is not well known. This study aimed to determine if patients with symptomatic benign prostatic hyperplasia (BPH) are at increased risk of PJI. METHODS A total of 12,902 male patients who underwent primary or revision total joint arthroplasty from January 2006 to April 2017 were retrospectively identified. The mean patient age was 62.47 years and the mean patient body mass index was 30.1 kg/m. The majority of patients were Caucasian or African American. Most surgical procedures involved the hip joints (57.8%) and were primary arthroplasties (86%). Of these patients, 386 (3%) had symptomatic BPH. Among this group, 250 patients with symptomatic BPH were identified and were matched in an approximate 13 ratio with 708 control patients. Using the International Consensus Meeting criteria, patients who developed PJI were identified. RESULTS The PJI rate was 7.9% in the symptomatic BPH group and 2.8% in the control group. Multivariate regression analysis in unmatched groups showed that symptomatic BPH was a strong independent risk factor for PJI. After matching for variables related to outcomes, symptomatic BPH remained a significant risk factor for PJI (p = 0.01). CONCLUSIONS Patients with symptomatic BPH had a higher risk of PJI compared with the control patients. This may partly explain the higher rate of PJI that is seen in male patients.

OBJECTIVE This study was performed to review our surgical method of vertical midface lifting in Asian patients and evaluate the clinical outcomes. METHODS AND MATERIALS This retrospective observational study involved 116 Asian women who complained of an aged midface. All patients underwent midface rejuvenation surgery with one lower eyelid incision and 2 small frontal-temporal incisions. Clinical results were assessed objectively using photographs and subjectively by a patient satisfaction survey. RESULTS All patients recovered well without major complications. High patient satisfaction (94%) was attained. The improvement scores as evaluated by the panel demonstrated a higher level of improvement for the malar eminence (8.3 ± 0.6), nasojugal groove (8.0 ± 0.8), and nasolabial fold (7.9 ± 0.7) than for the lower face (6.2 ± 1.0). CONCLUSION Our vertical midface lift technique is safe and effective for older Asian patients with a midface aging appearance. LEVEL OF EVIDENCE Therapeutic IV.BACKGROUND Few publications have addressed nasal valve (NV) insufficiency as a complication of Mohs micrographic surgery. OBJECTIVE To comprehensively review the literature and further characterize the causes, prevalence, evaluation, and management of NV insufficiency as it relates to cutaneous oncology. MATERIALS AND METHODS A PubMed search was completed to identify articles related to the NV in the context of Mohs micrographic surgery, cutaneous oncology, and reconstruction. RESULTS Nasal valve insufficiency may occur during tumor removal and/or reconstruction. Defect size larger than 1 cm; location on the ala, sidewall, or alar crease; lack of structural support; and poorly planned flaps are the main risk factors for NV insufficiency. Several surgical techniques have been described to avoid and correct this complication. CONCLUSION Nasal valve insufficiency may be an underrecognized and underreported complication of Mohs micrographic surgery. Nasal valve insufficiency may be identified with relatively simple tests. Knowledge of NV anatomy and preoperative function assessment is essential. Recognition of this potential complication and awareness of its prevention and management may decrease morbidity in patients undergoing cutaneous surgery.
