Resurfacing Capitate Pyrocarbon Implant Without Capitate Pole Resection to Improve Clinical Results in the Treatment of Chronic Wrist Arthritis

Proximal row carpectomy (PRC) is a long-time, well-accepted, easy-to-reproduce procedure for the treatment of several painful degenerative conditions of the wrist, when capitate pole and radius lunate fossa are preserved. It has been reported to relieve pain and preserve a substantial wrist range of motion, although a partial loss of strength has to be expected because of the decreased length of the carpus. Since 2010, a new technique has been described in the literature using the resurfacing capitate pyrocarbon implant, combined with PRC. This implant has been designed to perform PRC even in the presence of degenerate joint surfaces, and thus resolves the limited indications of this procedure; however, if a resection of the capitate pole is performed to set up the implant, similar to PRC it may not positively influence the recovery of strength. The authors propose an resurfacing capitate pyrocarbon implant technique without any capitate bone resection, to preserve as much as possible the carpus length and so to improve the functional recovery. The surgical technique, is described in detail and preliminary results are discussed.

We present the case of a 56-year-old patient, diagnosed with chronic gout for over 12 years, with tophi in the upper and lower limbs, who presented accusing mechanical pain in the left tibio-tarsal joint and impaired function of the hands. The clinical examination showed bilateral multiple destructive gout tophi in the hands, forearms, elbows, feet, ankles, and lower legs, while the left ankle exhibited an important varus deformity. Computed tomography examination of the left ankle showed multiple gout tophi with bone erosions and a bimalleolar pathological fracture. The patient underwent pharmacological treatment, physica...

Chronic skeletal disorders (CSDs), including degenerative diseases such as osteoporosis (OP) and autoimmune disorders, have become a leading cause of disability in an ageing society, with natural drugs being indispensable therapeutic options. The clinical safety evaluation (CSE) of natural drugs in CSDs has been given priority and has been intensively studied. To provide fundamental evidence for the clinical application of natural drugs in the elderly population, clinical studies of natural drugs in CSDs included in this review were selected from CNKI, Web of Science, PubMed, Science Direct and Google Scholar since 2001. S...

Chest. 2022 Jan;161(1):e35-e41. doi: 10.1016/j.chest.2021.08.065.ABSTRACTA 71-year-old man with history of gastroesophageal reflux disease, chronic sinusitis, arthritis, hypothyroidism, and anemia of chronic disease initially sought treatment with a recurrent left pleural effusion along with other abnormal lung findings on chest CT scan. Before his referral, he was being managed for 3 years at his local hospital for waxing and waning fevers, fatigue, productive cough, chills, and night sweats. He did not report any hemoptysis or chest pain, but reported weight loss of 13 kgs in 15 months. During those 3 years, he was treat...

Numerous studies have explored pain in minoritized groups, but they infrequently include Native Americans (NAs)1,24. This is a problem because NAs have the highest prevalence rates of disability, migraines, comorbidity with psychiatric disorders, rheumatoid arthritis, juvenile arthritis, chronic joint symptoms, lower back, neck, face, jaw and dental pain than other minoritized groups7,28,38,71,75,88,89.

ConclusionsNo effect was found of duloxetine added to usual care compared to usual care alone in patients with chronic OA pain. For patients with symptoms of centralized pain our results need to be confirmed in another trial.

CONCLUSIONS: Screening for an MSD and associated comorbidities could prevent the transition of acute conditions to chronic conditions. If PCPs can identify predictors and factors associated with an MSD, they may be able to screen for MSDs more effectively. Earlier identification of MSDs may facilitate earlier treatment and prevent costs associated with resulting chronic disorders and persistent pain and disability.PMID:34997837 | DOI:10.1515/jom-2021-0185

CONCLUSION: The findings emphasize the detrimental effects of osteoarthritic symptoms on disability through frailty, and the moderated mediation results suggest that these effects were conditional on physical resilience, which is a modifiable internal resource of individuals. When planning nursing interventions for older adults with osteoarthritis, nurses need to consider physical resilience as a moderator to prevent frailty and disability.PMID:34990022 | DOI:10.1111/jan.15135

J Biochem. 2021 Dec 30:mvab143. doi: 10.1093/jb/mvab143. Online ahead of print.ABSTRACTIn addition to diurnal rhythms in physiology and behavior, a variety of pathological conditions also exhibit marked day-night changes in symptom intensity, exemplified by allergic rhinitis, arthritis, asthma, myocardial infarction, congestive heart failure, stroke, and chronic pain disorders. Currently, novel therapeutic approaches are facilitated by the development of chemical compounds targeted to key proteins that cause diurnal exacerbation of pathological events. Neuropathic pain is a chronic condition that occurs by tumor-induced ne...
