Around 1 in 5 patients undergoing resection of a T4 colorectal carcinoma either have PC during primary resection or develop PC during follow-up. N stage was associated with PC in the entire study population. However, none of the clinical or pathological variables were associated with the risk of metachronous PC and therefore cannot be used to develop targeted surveillance strategies.

Purpose Initial treatment for symptomatic carpometacarpal (CMC) osteoarthritis (OA) of the thumb is usually nonsurgical. However, evidence on the effect of a hand orthosis and hand therapy for mid-and long-term results is limited, and it is unknown how many patients undergo additional surgical treatment. Therefore, the aim of this study is to describe the outcome of a hand orthosis and hand therapy for CMC OA in a large cohort study, and to evaluate the conversion rate to surgical treatment.Methods In this multicenter, prospective cohort study, patients treated with a hand orthosis and hand therapy for primary CMC OA between 2011 and 2014 were included. Pain (visual analog scale) and function (Michigan Hand Questionnaire) were measured at baseline, 6 weeks, 3 months, and at 12 months after the start of treatment. All patients converted to surgery were recorded between 2012 and 2016. Outcome was compared with baseline, and post hoc comparisons were made between patients who were not converted to surgery and patients who were converted to surgery after initially receiving a hand orthosis and hand therapy. Lastly, subgroup analysis was performed based on baseline pain levels.Results After a mean follow-up of 2.2 AE 0.9 years, 15% of all patients were surgically treated. In the group that was not converted to surgery, pain (visual analog scale) significantly improved from 49 AE 20 at baseline to 36 AE 24 at 12 months. The Michigan Hand Questionnaire score was essentially unchanged from 65 AE 15 at baseline to 69 AE 10 at 12 months. Post hoc testing showed that improvement in pain was only significant between baseline and 6 weeks, and thereafter stabilized until 1 year after the start of treatment. The group that converted to surgery did not show any improvement in pain and function at follow-up.Conclusions In this cohort of patients with thumb CMC OA who underwent hand therapy including an orthosis, 15% of the patients underwent additional surgical treatment. The patients (85%) who did not undergo surgery improved in pain and function, although only improvements in pain were significant and clinically relevant. Most improvement was seen in the first 6 weeks and stabilized till 1 year after the start of treatment.

BackgroundHypermobility of the first carpometacarpal joint is mostly surgically treated with a volar approached stabilization by Eaton, but recent studies indicate the importance of the dorsoradial and intermetacarpal ligaments (DRL and IML) for carpometacarpal joint stability. The aim of this study was to compare a dorsal and volar technique for primary carpometacarpal hypermobility regarding pain and functional outcome.MethodsPatients with non-degenerative, painful carpometacarpal hypermobility were included and were randomly assigned to either the volar technique using the FCR, or a dorsal technique using the ECRL. After premature termination of the trial, we followed all patients treated with the volar approach. Pain, strength, and ADL function using DASH and Michigan Hand Questionnaires (MHQ) were measured at baseline and 3 and 12 months after surgery.ResultsAfter including 16 patients, the randomized trial comparing the volar and dorsal technique was terminated because of significant increased pain in the dorsal group. Although none of the other outcome measures were significant in the underpowered comparison, in line with the pain scores, all variables showed a trend towards a worse outcome in the dorsal group. Between 2009 and 2012, 57 thumbs were surgically stabilized. We found significant better pain and MHQ scores, and after 1 year improved grip and key pinch strength. Patients returned to work within 8 (±7) weeks, of which 85 % in their original job.ConclusionsSurgical stabilization of the thumb is an effective method for patients suffering from hypermobility regarding pain, daily function, and strength. We recommend a volar approach.Level of Evidence: Level I, therapeutic study
