We investigated the union rate, the period until union, unilateral or bilateral, vertebral level, laterality (right or left), and pathological stage at the first visit.

Direct reduction and repair of spondylolysis with grade 1 slip using the smiley face rod: a case report.

Lumbar spondylolysis, caused by stress fracture of the pars interarticularis may lead to a bony defect or spondylolisthesis. In adolescents, its surgical treatment employs the smiley face rod method for direct reduction of pseudoarthrotic spondylolysis and spondylolisthesis. Clinical outcomes of this treatment have been occasionally described; however, implant removal has not been discussed previously.

Recurrent hemarthrosis after total knee arthroplasty in rheumatoid arthritis successfully treated with selective embolization: A case report.

Recurrent hemarthrosis after total knee arthroplasty is a rare complication. This usually occurs in osteoarthritis, but is relatively rare in rheumatoid arthritis. This is a report of recurrent hemarthrosis after total knee arthroplasty in a rheumatoid arthritis patient.

Characteristics of adolescent lumbar spondylolysis with acute unilateral fatigue fracture and contralateral pseudoarthrosis.

This study aimed to examine the characteristics of lumbar spondylolysis with acute lumbar spondylolysis on one side and pseudoarthrotic spondylolysis on the other, relative to acute lumbar spondylolysis on one side only. Short-tau inversion recovery images obtained through magnetic resonance imaging were used to diagnose 58 patients with acute lumbar spondylolysis with bone marrow edema on one side only. A total of 20 patients who had pars defects on the contralateral side (terminal-stage pseudoarthrotic spondylolysis) were included in the contralateral pseudoarthrosis group (P group).

Short-Term Effects of Early Postoperative Celecoxib Administration for Pain, Sleep Quality, and Range of Motion After Total Knee Arthroplasty: A Randomized Controlled Trial.

Background: We hypothesized that early postoperative administration of celecoxib would reduce pain scores and improve sleep quality and active range of motion after total knee arthroplasty (TKA) under general anesthesia.

Methods: Patients in the celecoxib group received 400 mg of celecoxib 2 hours after TKA, followed 6 hours later by 200 mg of celecoxib. Patients in the control group received 400 mg of celecoxib the second day after surgery.

Clinical features of spontaneous spinal epidural hematoma.

Spontaneous spinal epidural hematoma is rare and therefore difficult to diagnose. This study evaluated the clinical features of this condition in patients admitted to our hospital. We evaluated 12 patients with spontaneous spinal epidural hematoma who were treated at our hospital.

We then stratified their pathological stage using a modified classification system via magnetic resonance imaging and computed tomography.

Charcot spinal arthropathy presenting as adjacent segment disease after lumbar spinal fusion surgery in Parkinson's disease: A case report.

Charcot spinal arthropathy (CSA) is a rare spinal disorder presenting neuropathic osteoarthropathy of facet joints leading to progressive destruction. After L4-5 PLIF, a 63-year-old woman with Parkinson's disease (PD) underwent L3-4 and L5-S1 PLIF for primary adjacent segment disease caused by degenerative change, which was found as facet joint osteophytes and a vacuum disc phenomenon with endplate sclerosis. However, her postural disorder from PD deteriorated, and strong opioid analgesics were administered for severe recurring low back pain.

Arthroscopic treatment of intra-articular dysplasia epiphysealis hemimelica of the knee.

Dysplasia epiphysealis hemimelica, also known as Trevor Fairbank disease, is characterized by asymmetrical osteochondral overgrowth of the epiphyseal cartilage. The clinical presentation of dysplasia epiphysealis hemimelica is wide and variable, depending on the site of the lesion. Herein, we describe the physical examination of a 9-year-old boy with intra-articular dysplasia epiphysealis hemimelica, in whom the symptoms were elicited on "reverse Wilson's sign": bending the knee from 70° to 120° against resistance while externally rotating the tibia.

Arthroscopic synovectomy for the treatment of stage II to IV trapeziometacarpal joint arthritis.

As a minimal invasive surgery for the treatment of thumb carpometacarpal joint (trapeziometacarpal [TMC]) arthritis, we performed an arthroscopic synovectomy for Eaton stage II to IV arthritis. We included patients who were effectively treated with a corticosteroid injection, experienced recurrence of TMC pain, and had no major instability of the TMC. Surgery was performed in 17 female patients.

Proximal Femoral Fracture in Hip Arthrodesis Treated with Double Reconstruction Plates.

We present a rare clinical case of a 90-year-old female who sustained a proximal femoral neck fracture following long-standing hip arthrodesis. Since the fracture occurred relatively proximally and involved the pelvis, double-plate fixation was chosen to achieve rigid fixation. The reconstruction plate was placed at the posterior and anterior columns individually through single vertical incision.

Effects of postoperative administration of celecoxib on pain management in patients after total knee arthroplasty: study protocol for an open-label randomized controlled trial.

Background: Multimodal analgesia is achieved by combining different analgesics and different methods of analgesic administration, synergistically providing superior pain relief when compared with conventional analgesia. Multimodal analgesia can also result in reductions in the side effects and complications of analgesia, thereby improving patient safety. Preventive analgesia, treatment before initiation of the surgical procedure, has a potential to be more effective in reducing pain sensitization than treatment initiated after surgery.
