➢ Adult-acquired flatfoot deformity is a complex process attributed mainly to posterior tibial tendon insufficiency.➢ Thorough physical examination and radiographs of the foot and ankle are usually adequate to achieve diagnosis.➢ Nonoperative management is the first line of treatment and has a reported success rate ranging from 67% to 90%.➢ A multitude of surgical options are available, particularly for stage II, with no consensus on the best options.➢ Fusions are associated with poor outcomes; hence, there is a trend toward earlier reconstruction before arthritis ensues.

Rotator cuff injuries in the pediatric and adolescent population are rare. These injuries are normally caused by an acute event or by repeated microtrauma as a result of poor mechanics during overhead sporting activities. Overall, these injuries account for fewer than 1% of all rotator cuff tears. Physeal injuries, tuberosity avulsions ("rotator cuff equivalents"), and proximal humeral fractures commonly occur in the pediatric population. Traumatic full-thickness rotator cuff ruptures that occur in this age group during contact sports are an extremely uncommon cause of shoulder pain. The rarity of this type of injury in the pediatric and adolescent population may be the result of the excellent tensile properties of rotator tendons in childhood that often resist mechanical forces better than the growth plate or the apophyses. This report describes a full-thickness rotator cuff tear and a posterior labral tear in a 12-year-old boy who had a direct injury to the shoulder while playing football. The authors' goal in reporting this case is to increase orthopedic surgeons' awareness of this type of injury. Early use of magnetic resonance imaging for persistent shoulder pain after direct injury during contact sports may avoid undue delay in diagnosis. This report also describes the mini-open transosseous extraphyseal technique of cuff repair and reviews the literature on this infrequent injury. Overall, excellent clinical outcomes and return to sports can be expected after surgical repair of torn and often retracted tendons.

Objectives: To compare anterior hook plating with established fixation constructs biomechanically and report outcomes and complications in a cohort of patella fractures treated with the technique.Design: Laboratory-based biomechanical study and clinical multicenter retrospective cohort study.Setting: 2 US Level 1 trauma centers.Patients/Participants: 51 patients (28 M and 23 F) with 30 simple transverse and 21 comminuted patella fractures. Thirty-six cadaveric patellae were used for the biomechanical study.Intervention: Biomechanical-dorsal plating was compared with cerclage wiring and modified tension band cable fixation in a comminuted patella fracture model in 36 cadaveric patellae. Constructs were tested at 08 and 45 degrees of flexion. Clinical-we reviewed a consecutive series of patella fractures in 2 centers for outcome and complications.Main Outcome Measurements: Biomechanical-construct stiffness. Clinical-reduction, union, complications, and range of motion.Results: Stiffness was greatest in dorsal plating at both 08 and 45 degrees. Dorsal plating (976 N, 1643 N) . modified tension band (317 N, 297 N) . cerclage (89.8 N, 150.3 N) at 0 and 45 degrees, respectively. 51 patients with patella fractures had them fixed with dorsal 2.7-mm mini fragment plates including a distal to proximal lag screw through the plate from the nose of the patella. 9 cases were small distal fragments not easily managed with screws and cables. All patients were followed up to union. There were 2 infections (1 superficial and 1 deep with nonunion), and 5 had implant removal (9.8%).Conclusions: Dorsal plating is biomechanically and clinically superior to modified tension band and cerclage techniques in comminuted patella fractures. This method allows for fixation of small distal pole fractures.

Introduction: Homelessness is a key social determinant of health, and the patient population has grown to over 580,000. Total joint arthroplasty (TJA) is an effective treatment of symptomatic end-stage osteoarthritis of the hip and knee and has been shown to improve health-related quality of life in the general population. However, the literature on the outcomes of TJA among homeless patients is limited. Methods: We retrospectively reviewed 442 patients who underwent primary, unilateral TJA between June 1, 2016, and August 31, 2017, at an urban, tertiary, academic safety net hospital. Based on self-reported living status, we classified 28 homeless patients and 414 control nonhomeless patients. Fisher exact tests, Student t-tests, and multivariate logistic regression were used to compare the demographics, preoperative conditions, and surgical outcomes between the two groups. Results: The homeless group were younger, more often male, and smokers; had alcohol use disorder; and used illicit drugs. After controlling for age, sex, and preoperative medical and social conditions, homeless patients were 15.83 times more likely to have an emergency department visit (adjusted odds ratio, 15.83; 95% confidence interval, 5.05 to 49.59; P , 0.0001) within 90 days but had similar rates of readmission (P = 0.25), revision surgery (P = 0.38), and prosthetic joint infection (P = 0.25) when compared with nonhomeless patients. Discussion: Although homeless patients did not have higher rates of readmission or revision surgery, homelessness still presents unique challenges for the TJA patients and providers. With careful preoperative optimization and collaborative support, however, the benefits of TJA may outweigh the risk of poor outcomes for these patients.

A 71-year-old man presented with a productive cough consisting of yellow fluid. He had previously been treated for pneumonia without resolution in his symptoms. Sputum was tested for bilirubin using a urine dipstick given its similar appearance to bile, which was positive. Hepatobiliary scintigraphy scan revealed uptake of radiotracer in the right lower lobe of the lung. Endoscopic retrogade cholangiopancreatography confirmed diagnosis of a bronchobiliary fistula. The patient had a stent placed in the common bile duct promoting anterograde bile flow with complete resolution of symptoms.
