Temporal Alignment of Dual Monitor Accelerometry Recordings.

Sensors (Basel) 2021 Jul 13;21(14). Epub 2021 Jul 13.

Centre for Research in Childhood Health/Research Unit for Exercise Epidemiology, Department of Sports Science and Clinical Biomechanics, University of Southern Denmark, 5220 Odense, Denmark.

Combining accelerometry from multiple independent activity monitors worn by the same subject have gained widespread interest with the assessment of physical activity behavior. However, a difference in the real time clock accuracy of the activity monitor introduces a substantial temporal misalignment with long duration recordings which is commonly not considered. In this study, a novel method not requiring human interaction is described for the temporal alignment of triaxial acceleration measured with two independent activity monitors and evaluating the performance with the misalignment manually identified.

Operative technique of distal radius resection and wrist fusion with iliac crest bone graft.

J Clin Orthop Trauma 2021 Aug 8;19:17-20. Epub 2021 May 8.

Department of Surgical Oncology, Tata Memorial Hospital, Homi Bhabha National Institute (HBNI), Mumbai, India.

Malignant lesions of distal radius and appropriately selected cases of benign aggressive lesions (giant cell tumor) of distal radius require resection for limb salvage. Post resection, reconstruction of that defect can be accomplished by either arthrodesis or arthroplasty both having their own pros and cons. In cases undergoing arthrodesis as modality of reconstruction, small defects (≤6 cm) can be reconstructed using autologous iliac crest bone graft which results in good cosmetic appearance and functional outcome.

Kienbock's Disease: Treatment Options - A Search for the Apt!

J Hand Surg Asian Pac Vol 2021 Jun;26(2):142-151

Department of Plastic Surgery, Hand & Reconstructive Microsurgery & Burns, Ganga Hospital, Coimbatore, India.

Kienbock's disease remains a condition of uncertain etiology and our understanding about the pathogenesis is still evolving. However, a lack of consensus on the treatment is the most striking as there are wide array of treatment options described ranging from 'doing nothing' to a free vascularized bone graft reconstruction of the lunate. Furthermore, most treatment modalities report equivalent success rate but cumulative evidence is lacking. Read More

Congenital Radioulnar Synostosis.

J Am Acad Orthop Surg 2021 07;29(13):563-570

From the Department of Orthopaedics, Mount Carmel Health System, Columbus, OH (Rutkowski), and the Department of Orthopedic Surgery, Nationwide Children's Hospital, Columbus, OH (Samora).

Congenital radioulnar synostosis is a rare condition resulting in fusion of the proximal portions of the radius and ulna. Patients commonly present in early childhood with functional deficits because of limited forearm rotation and fixed positioning of the forearm. Compensatory motion and hypermobility are frequently observed at the wrist and shoulder, which may predispose these joints to overuse injury. Read More

A Feasibility Study of the Use of Smartwatches in Wearable Fall Detection Systems.

Sensors (Basel) 2021 Mar 23;21(6). Epub 2021 Mar 23.

Departamento de Tecnología Electrónica, Universidad de Málaga, ETSI Telecomunicación, 29071 Málaga, Spain.

Over the last few years, the use of smartwatches in automatic Fall Detection Systems (FDSs) has aroused great interest in the research of new wearable telemonitoring systems for the elderly. In contrast with other approaches to the problem of fall detection, smartwatch-based FDSs can benefit from the widespread acceptance, ergonomics, low cost, networking interfaces, and sensors that these devices provide. However, the scientific literature has shown that, due to the freedom of movement of the arms, the wrist is usually not the most appropriate position to unambiguously characterize the dynamics of the human body during falls, as many conventional activities of daily living that involve a vigorous motion of the hands may be easily misinterpreted as falls.

Sensors (Basel) 2021 Mar 9;21(5). Epub 2021 Mar 9.

Department of Intelligent Systems, Jožef Stefan Institute, 1000 Ljubljana, Slovenia.

Understanding people's eating habits plays a crucial role in interventions promoting a healthy lifestyle. This requires objective measurement of the time at which a meal takes place, the duration of the meal, and what the individual eats. Smartwatches and similar wrist-worn devices are an emerging technology that offers the possibility of practical and real-time eating monitoring in an unobtrusive, accessible, and affordable way.

J Plast Surg Hand Surg 2021 Mar 18:1-7. Epub 2021 Mar 18.

Division of Orthopaedic Surgery, Oslo University Hospital, Oslo, Norway.

Four corner fusion (4CF) is a limited wrist arthrodesis offered to patients with painful wrists due to scaphoid non-union advanced collapse (SNAC) or scapho-lunate advanced collapse (SLAC). A retrospective study of 42 wrists (in 36 patients), operated with 4CF using K-wires and autologous bone graft followed up after 11 (4-19) years was performed, 25 were male and mean age at surgery was 51 (22-71) years. During the follow-up period, 13 wrists were converted to total wrist arthrodesis or wrist arthroplasty, and one is scheduled for conversion (14/42, 33%) due to non-union (3), DISI and progressing arthrosis (7) or progressing arthrosis (4).
