ObjectiveTo investigate the outcomes of hip arthroscopy for femoroacetabular impingement (FAI) in patients over the age of 50 years.MethodThis is a therapeutic case series study. A total of 27 FAI patients over the age of 50 years who met inclusion and exclusion criteria and were being followed up for at least 2 years in the orthopaedics department at our hospital between January 2015 and October 2017 were recruited for a prospective analysis on the outcomes of hip arthroscopy. All patients underwent unilateral surgery. Of the patients included, there were 15 men and 12 women, who were aged 50–74 years old (57 ± 6.4 years). The outcomes were assessed using the visual analog scale (VAS), the modified Harris hip score (mHHS), and the International Hip Outcome Tool (iHOT‐12).ResultsA total of 27 patients were followed up for at least 2 years. The postoperative center‐edge angle, the alpha angle, and the offset decreased significantly compared with preoperative measurements (P < 0.01). The mHHS before surgery and at 1 year and 2 years after surgery was 62.19 ± 7.47, 86.70 ± 5.80, and 87.89 ± 5.08, respectively; iHOT‐12 scores were 30.44 ± 4.22, 73.56 ± 3.89, and 73.77 ± 3.72, respectively; VAS scores were 6.07 ± 0.78, 1.93 ± 0.73, and 1.59 ± 0.64, respectively. As compared with the condition before surgery, there was a significant improvement in the mHHS, iHOT‐12, and VAS scores at 1 year and 2 years after surgery (P < 0.01). The mHHS score at 2‐year follow up after surgery was higher than that at 1 year after surgery, and the difference observed was statistically significant (P = 0.04). One patient with severe acetabular and femoral cartilage damage underwent total hip replacement 11 months after surgery.ConclusionHip arthroscopy considerably improved hip symptoms and function in Chinese FAI patients aged 50 years or older who did not have severe radiographic osteoarthritis. The conversion to THA and complications were low. Strict surgical indications and appropriate surgical strategies lay the foundation for satisfactory postoperative results in elderly patients with FAI.

Numerous arthroplasty techniques had been reported for the treatment of thumb carpometacarpal (CMC) joint osteoarthritis. The purpose of our study is to evaluate long-term clinical and radiographic outcomes of patients who underwent modified trapeziectomy with ligament reconstruction tendon interposition (LRTI).Our retrospective study included 20 consecutive patients with advanced thumb CMC arthritis receiving modified trapeziectomy with LRTI (20 thumbs). For clinical evaluation, we assessed visual analogue scale (VAS), Disabilities of the Arm, Shoulder and Hand (DASH) scores and Kapandji index. Additionally, the grip, pinch power and waist flexion power, radial and volar abduction angle were evaluated, As for radiologic evaluation, we just estimated height of the trapezial space.We took 2-year follow-up. All patients showed decreased VAS from 6.8 preoperatively to 1.4. Mean DASH and Kapandji scores were improved from 52.2 preoperatively to 21.6 and from 6.4 preoperatively to 7.4, respectively. Compared to preoperative range of motion (ROM) for radial abduction and volar abduction, both markedly increased at 2-year follow-up (from 61.2 to 80.1, from 60.6 to 78.3, respectively). Besides, mean power improved from 15.9 preoperatively to 21.7 kg at 2-year follow-up for grip power, from 1.9 preoperatively to 3.5 kg at 2-year follow-up for tip pinch; however, mean waist flexion power showed no significant change from 20.5 preoperatively to 19.7 kg at 2-year follow-up. Notably, there was no significant sinking in height of the trapezial space from 10.0 preoperatively to 9.6 mm at 2-year follow-up. NO case had a complication at final follow-up.Modified trapeziectomy with LRTI treating thumb CMC arthritis in Eaton stage III–IV had a satisfactory efficacy. This new procedure is able to provides enough support for thumb to prevents thumb sinking.

The shape of PCP is various, and the analysis of its relationship to the important structures around it is of great value. In addition, the preoperative radiological evaluation plays a major role in patients considered for endoscopic sinus surgery. Detailed preoperative analysis of the anatomy of the sphenoid sinus and its boundaries is crucial in facilitating entry to the pituitary fossa and reducing intraoperative complications.

Rationale:Necrotizing fasciitis (NF), characterized by widespread fascial necrosis, is a rare disease in clinic. Fournier gangrene (FG) is a special type of NF involved of perineum and scrotum. To our knowledge, no article has reported on bilateral femoral posterior neurocutaneous perforater flap treating for FG.Patient concerns:A 61-year-old Chinese male complained of perineal skin necrosis for 19 days. The patient received treatment in other hospital due to chronic bronchitis on April 15th and body temperature ranged from 38 to 39 °C. Then he received antiinfection therapy. Perianal cutaneous occurred mild necrosis on May 08th. And the necrosis generally deteriorated. He came to our hospital for treating necrosis in area of perineum and scrotum on May 28th.Diagnoses:He was diagnosed with FG and chronic bronchitis.Interventions:The patient underwent debridement on June 2nd and received bilateral femoral posterior neurocutaneous perforater flap on June 29th. Besides, the patient was treated with whole-body nutrition support and antibiotic treatment.Outcomes:One week after the 2nd operation, the flap showed normal color. The result shows good outcome and no recurrence of the clinical symptoms occur till now.Lessons:FG is rare. Bilateral femoral posterior neurocutaneous perforater flap is an effective procedure to treat FG. The outcome of combined therapy is satisfactory.
