An inverted labrum was present in 10% (22/229) of all hips. The incidence of Pavlik harness treatment failure was 91% (20/22) in the inverted labrum group compared with 27% (55/207) in the control group (P<0.001). Closed or open reduction was required in 86% (15/22) of the inverted labrum group compared with 3% (7/207) of hips in the control group (P<0.001). The incidence of avascular necrosis was 18% (4/22) in hips with an inverted labrum compared with 0.4% (1/207) in the control group (P<0.001).

In children with DDH undergoing index treatment in a Pavlik harness, the presence of an inverted acetabular labrum is strongly predictive of treatment failure. Dysplastic hips with an inverted labrum also have a significantly higher risk of requiring closed or open reduction and developing avascular necrosis compared with those without an inverted labrum.

The ability to estimate skeletal maturity using a hip radiograph does not yet exist, but may have utility in the treatment of scoliosis, slipped capital femoral epiphysis, and lower limb deformity. We sought to develop a fast, accurate, and reproducible method.

Fourteen hip radiologic parameters were evaluated on serial anteroposterior hip radiographs from 3 years before to 2 years after the skeletal age associated with 90% of final height, a validated skeletal maturity definition which correlates with the timing of peak height velocity. The Greulich and Pyle (GP) left hand bone age was obtained for comparison. Stepwise linear regression and generalized estimating equation analyses were used to isolate key hip and demographic parameters, creating the "optimized Oxford" skeletal maturity system. The accuracy of the optimized Oxford system in predicting years from 90% of final height was evaluated and compared with systems of demographics only, the modified Oxford, demographics+modified Oxford, and demograporms as accurately as GP.
We have developed a skeletal maturity system that utilizes anteroposterior hip radiographs and performs as accurately as GP.
We conducted a large, U.S wide, observational study of type III tibial fractures, with the hypothesis that delays between definitive fixation and flap coverage might be a substantial modifiable risk factor associated with nosocomial wound infection.

A retrospective analysis of a multicenter database of open tibial fractures requiring flap coverage.

Fourteen level-1 trauma centers across the United States.

Two hundred ninety-six (n = 296) consecutive patients with Gustilo III open tibial fractures requiring flap coverage at 14 trauma centers were retrospectively analyzed from a large orthopaedic trauma registry. We collected demographics and the details of surgical care. We investigated the patient, and treatment factors leading to infection, including the time from various points in care to the time of soft-tissue coverage.

Delay definitive fixation and flap coverage in tibial type III fractures.

(1) Results of multivariate regression with time from injury to coverage, debridement to coverage, andthat facilitate coordination of definitive fixation and flap coverage, will reduce the infection rates in Gustilo type III tibial fractures.

To document union rate, complications and patient-reported outcomes after open reduction and internal fixation (ORIF), with and without bone grafting (BG), for humeral diaphyseal nonunion after failed nonoperative management.

Retrospective.

University teaching hospital.

From 2008 to 2017, 86 consecutive patients [mean age 59 years (range 17-86), 71% (n = 61/86) women] underwent nonunion ORIF (plate and screws) at a mean of 7 months postinjury (range 3-21.5). Eleven (13%) underwent supplementary BG.

Union rate and complications for 83 patients (97%) at a mean of 10 months (3-61). Patient-reported outcomes (QuickDASH, EQ-5D, EQ-VAS, SF-12, satisfaction) for 53 living, cognitively-intact patients (78%) at a mean of 4.9 years (0.3-9.2).

Ninety-three percent (n = 77/83) achieved union after nonunion ORIF. Complications included recalcitrant nonunion (7%, n = 6/83), iatrogenic radial nerve palsy (6%, n = 5/83), infection (superficial 7%, n = 6/83; deep 2%, n = 2/83), and iliac crest donor site morbidity (38%, n = 3/8). Lithocholicacid The union rate with BG was 78% (n = 7/9) and without was 95% (n = 70/74; P = 0.125), and was not associated with the nonunion type (atrophic 91%, n = 53/58; hypertrophic 96%, n = 24/25; P = 0.663). Median QuickDASH was 22.7 (0-95), EQ-5D 0.710 (-0.181-1), EQ-visual analog scale 80 (10-100), SF-12 physical component summary 41.9 (16-60.5), and mental component summary 52.6 (18.7-67.7). Nineteen percent (n = 10/53) were dissatisfied with their outcome.

ORIF for humeral diaphyseal nonunion was associated with a high rate of union. Routine BG was not required and avoided the risk of donor site morbidity. One in 5 patients were dissatisfied despite the majority achieving union.

To assess the effectiveness of suprapatellar (SP)-nailing versus infrapatellar (IP)-nailing of tibia fractures in anterior knee pain, complications (retropatellar chondropathy, infection, and malalignment) and physical functioning and quality of life. A clinical question-driven and thorough systematic review of current literature is provided.

PubMed and Embase databases were searched for studies published between 2010 and 2020 relating to SP and IP-nailing of tibia fractures. The study is performed in concordance with PRISMA-guidelines.

Studies eligible for inclusion were randomized controlled trials, prospective and retrospective observational studies reporting on outcomes of interest.

Data extraction was performed independently by 2 assessors. Methodological quality and risk of bias was assessed according to the guidelines of the McMaster Critical Appraisal.

Continuous variables are presented as means with SD and dichotomous variables as frequency and percentages. The weighted mean, standardized weighted mean differences, and 95% confidence interval were calculated.
