Usefulness of Sarilumab in Patients with Rheumatoid Arthritis after Regression of Lymphoproliferative Disorders.

Lymphoproliferative disorders (LPDs) are serious complications associated with rheumatoid arthritis (RA) treatment that mostly occur during methotrexate (MTX) treatment. Cessation of MTX may induce regression of LPDs but is often followed by a flare of RA. Here, we describe two patients with RA flares after the discontinuation of MTX due to LPDs and sarilumab was useful for the treatment of RA without a relapse of LPDs.

Return to Sports Activity After Microfracture for Osteochondral Lesion of the Talus in Skeletally Immature Children.

Retrograde Drilling for Osteochondral Lesions of the Talus in Skeletally Immature Children.

Background: Osteochondral lesions of the talus (OLTs) involve damage to the cartilage and subchondral bone and are infrequent in children. Clinicians usually attempt nonsurgical treatment of OLTs first, and subsequently progress to surgical treatments, including retrograde drilling (RD), if the initial outcomes are insufficient. Good clinical outcomes of RD have been reported.

Effect of minimally invasive distal first metatarsal osteotomy on blood flow of the metatarsal head.

Background: Distal first metatarsal osteotomy is an option for operative treatment of mild to severe hallux valgus (HV) deformities. Minimally invasive distal linear metatarsal osteotomy (DLMO) provides good outcomes without avascular necrosis (AVN) of the metatarsal head. However, no reports have described the in vivo blood flow changes in the metatarsal head after osteotomy.

Optimal suture anchor direction in arthroscopic lateral ankle ligament repair.

We examined the reliability of ultrasonography for detecting pseudotumors in comparison with MRI.

Simultaneous use of lateral calcaneal ostectomy and subtalar arthroscopic debridement for residual pain after a calcaneal fracture.

Inadequate primary treatment of calcaneal fractures frequently results in persistent, residual pain. This can be caused by subtalar arthritis, an increased calcaneal width, and/or calcaneal fibular impingement of the peroneal tendons. Many patients experience multiple disorders simultaneously, requiring a combination of procedures to treat the injury.

Does the addition of computed tomography to computed radiography provide more value to final outcomes and treatment decisions in displaced intra-articular calcaneal fractures?
