Cryoneurolysis to treat the pain and symptoms of knee osteoarthritis: a multicenter, randomized, double-blind, sham-controlled trial.

Objective: Evaluate the efficacy and safety/tolerability of cryoneurolysis for reduction of pain and symptoms associated with knee osteoarthritis (OA).

Design: Randomized, double-blind, sham-controlled, multicenter trial with a 6-month follow-up in patients with mild-to-moderate knee OA. Patients were randomized 2:1 to cryoneurolysis targeting the infrapatellar branch of the saphenous nerve (IPBSN) or sham treatment.

Intrathoracic fracture-dislocation of the proximal humerus treated with rib fixation and shoulder arthroplasty.

Proximal fractures of the humerus resulting in intrathoracic displacement of the humeral head are rare, but cause serious pain and can lead to pulmonary and glenohumeral complications. Many treatment options exist, but there is still no literature regarding mortality and morbidity associated with rib fixation in concordance with treatment of the proximal humerus. This case describes a patient who was treated using a multi-team approach that involved shoulder arthroplasty with rib fixation, and which resulted in decreased pain and decreased narcotic use while improving the patient's pulmonary function.

Osteonecrosis of the femoral head associated with slipped capital femoral epiphysis.

We performed a retrospective analysis of 212 patients (299 hips) with slipped capital femoral epiphysis (SCFE) over a 9-year period to assess the incidence of osteonecrosis of the femoral head. Risk factors for the occurrence of osteonecrosis and the influence of treatment on the development of osteonecrosis were determined. Osteonecrosis occurred in 4 hips with unstable SCFE (4/27) and did not occur in hips with stable SCFE (0/272).

Sonography of ovarian tumors: predictability of tumor type.

One hundred six ovarian neoplasms were evaluated with respect to size, echogenic characteristics, and percentage of echogenic material to determine if sonography could differentiate between malignant and benign tumors and if histology could be determined. This study indicates that anechoic lesions have high likelihood of being benign tumors, usually mucinous cystadenomas or serous cystadenomas. As the percentage of echogenic material increases, the likelihood of malignancy also increases.
