Introduction and Objective. Carpal tunnel syndrome (CTS) is a very common compressive neuropathy involving the median nerve. The typical symptoms are paraesthesia, dysesthesia and loss of strength; in severe case, this compression deteriorates the sensorimotor control of the hand and interferes with the adjustment of the forces at the level of the fingers, thus affecting the components that are the basis of dexterity and control of fine movements. For these reasons, the CTS has repercussions on various activities of daily life, including writing skills. Word processing via PC and mobile device (touch-typing) require a fine control of the hand-wrist movement and of the opposition of the thumb, while in handwriting, gripping and gripping movements are carried out in a protracted manner. In modern society, present skills play a role of fundamental importance from an educational, professional and social point of view. The aim of the study is to describe the effects of carpal tunnel release (CTR) on handwriting and digital writing performance. Materials and Methods. We recruited patients suffering from carpal tunnel syndrome (CTS) who were candidates for CTR surgery and collected clinical and demographic data, including age, occupation, duration of symptoms and electromyography outcomes. The first trial session was carried out before surgery and the subsequent ones at 1, 2, 3, 4, 8 and 12 weeks after the CTR. These trials involved copying a 500-character paragraph by handwriting, personal computer (PC) and mobile device, for which a dedicate Google Colab web page was computed. We used as parameters the speed, expressed in words per minute (wpm), and the accuracy of copying, which was measured in number of errors (en). Moreover in each session the patient filled in the QuickDASH (Disabilities of the Arm, Shoulder, and Hand) questionnaire. We used the one-way anova to evaluate the change in the three performances and in the QuickDASH score in follow-up sessions. We used the two-way anova to detect a possible interactions between speed improvement and groups of variables, namely gender, writing frequency, schooling, diabetes, dysthyroidism and metabolic syndrome. Results. We recruited 20 patients of whom 7 dropped out for personal reasons and 13 had completed all trial sessions. The PC writing performance had an average speed and accuracy of 15.1 ± 6.8 wpm and 13.1 ± 8.2 en, respectively, while post-operatively it returned values of 17.6 ± 5.0 wpm and 9.9 ± 5.6 en. Regarding touch-typing, a pre-operative average of 16.9 ± 5.8 wpm and 14.3 ± 14.4 en was recorded, while post-operatively an average of 21.7 ± 6.5 wpm and 11.5 ± 14.7 en was reported. Handwriting performance initially had a mean of 20.5 ± 7.1 wpm and 0.1 ± 0.6 en and after three months returned a mean of 22.4 ± 4.0 wpm and 0 ± 0 n. The QuickDASH score had a pre-operative mean of 39.1 ± 9.1 and post-operative mean of 17 ± 6 points. The only statistically significant improvements were those related to touch-typing (P = 0.022) and QuickDASH score (P < 0.001). There was no significant interaction between gender, comorbidity, writing frequency, level of schooling and recovery of writing ability. Conclusions. The data collected showed, in agreement with previous studies, that CTS has a significant impact on the patient's writing ability, who benefits from the surgical treatment, especially in terms of touch-typing and general manual dexterity. In addition, the recovery of writing ability did not show significant correlation with other variables

Recent studies on animal models focused on the effect of preserving tendon remnant of rotator cuff on tendon healing. A positive effect by combining tendon remnant preservation and small bone vents on the greater tuberosity in comparison with standard tendon-to-bone repair has been shown. The purpose of the present clinical study was to evaluate the efficacy of biologic augmentation of arthroscopic rotator cuff repair by maintaining tendon remnant on rotator cuff footprint combined with small bone vents of the greater tuberosity. A retrospective study was conducted. All patients who underwent arthroscopic rotator cuff repair associated with small bone vents (nanofractures) and tendon footprint preservation were considered eligible for the study. Inclusion criteria were: diagnosis of full-thickness rotator cuff tear as diagnosed at preoperative magnetic resonance imaging (MRI) and confirmed at the time of surgery; minimum 24-month of follow-up and availability of post-operative MRI performed not earlier than 6 months after surgery. Exclusion criteria were: partial thickness tears, irreparable tears, capsulo-labral pathologies, calcific tendonitis, gleno-humeral osteoarthritis and/or previous surgery. Primary outcome was the ASES score. Secondary outcomes were: Quick-DASH and WORC scores, and structural integrity of repaired tendons by magnetic resonance imaging (MRI) performed six months after surgery. A paired t-test was used to compare pre- and postoperative clinical outcomes. Subgroup analysis was performed according to tear size. Significance was set at p < 0.05. The study included 29 patients (M:F = 15:14). Mean age (+ SD) of patients was 61.7 + 8.9 years. Mean follow-up was 27.4 ± 2.3 months. Comparison between pre- and postoperative functional scores showed significant clinical improvement (p < 0.001). Subgroup analysis for tear size showed significant differences in the QuickDASH score (0.04). Particularly, a significant difference in the QuickDASH score could be detected between medium and large tears (p=0.008) as well as medium and massive lesions (p=0.04). No differences could be detected between large and massive tears (p= 0.35). Postoperative imaging showed healed tendons in 21 out of 29 (72%) cases. Preservation of tendon remnant combined with small bone vents in the repair of medium-to-massive full-thickness rotator cuff tears provided significant improvement in clinical outcome compared to baseline conditions with complete structural integrity in 72% of the cases

The purpose of this study is to report the clinical and radiological outcomes of patients undergoing primary or revision reverse total shoulder arthroplasty using custom 3D printed components to manage severe glenoid bone loss with a minimum of 2-year follow-up. After ethical approval (reference: 17/YH/0318), patients were identified and invited to participate in this observational study. Inclusion criteria included: 1) severe glenoid bone loss necessitating the need for custom implants; 2) patients with definitive glenoid and humeral components implanted more than 2 years prior; 3) ability to comply with patient reported outcome questionnaires. After seeking consent, included patients underwent clinical assessment utilising the Oxford Shoulder Score (OSS), Constant-Murley score, American Shoulder and Elbow Society Score (ASES), and quick Disabilities of the Arm, Shoulder, and Hand Score (quickDASH). Radiographic assessment included AP and axial projections. Patients were invited to attend a CT scan to confirm osseointegration. Statistical analysis utilised included descriptive statistics (mean and standard deviation) and paired t test for parametric data. 3 patients had revision surgery prior to the 2-year follow-up. Of these, 2/3 retained their custom glenoid components. 4 patients declined to participate. 5 patients were deceased at the time of commencement of the study. 21 patients were included in this analysis. The mean follow-up was 36.1 months from surgery (range 22–60.2 months). OSS improved from a mean 16 (SD 9.1) to 36 (SD 11.5) (p < 0.001). Constant-Murley score improved from mean 9 (SD 9.2) to 50 (SD 16.4) (p < 0.001). QuickDASH improved from mean 67 (SD 24) to 26 (SD 27.2) (p = 0.004). ASES improved from mean 28 (SD 24.8) to 70 (SD 23.9) (p = 0.007). Radiographic evaluation demonstrated good osseointegration in all 21 included patients. The utility of custom 3D-printed components for managing severe glenoid bone loss in primary and revision reverse total shoulder arthroplasty yields significant clinical improvements in this complex patient cohort

Abstract. Objectives. We aimed to evaluate if union of clavicle fractures can be predicted at six weeks post-injury by the presence of bridging callus detected by ultrasound. Methods. Adult patients who sustained a displaced midshaft clavicle were recruited prospectively. We assessed patient demographics, functional scores and radiographic predictors with a standardized protocol at six weeks. Ultrasound evaluation of the fracture site was undertaken to determine if sonographic bridging callus was present. Nonunion was determined by CT scanning at six months post-injury. Clinical features at six weeks were used to stratify patients at high risk of nonunion and a QuickDASH ≥40, fracture movement on examination or absence of callus on radiograph. Results. 112 patients completed follow-up at six months with a nonunion incidence of 17% (n=18/112). Sonographic bridging callus was detected in 62.5% (n=70/112) of the cohort at six weeks post-injury. If present, union occurred in 98.6% of the fractures (n=69/70). If absent, nonunion developed in 40.5% of cases (n=17/42). The sensitivity to predict union with sonographic bridging callus at six weeks was 73.4% and the specificity was 94.4%. Regression analysis found failure to detect sonographic bridging callus at six weeks was associated with nonunion, older age, female sex, and greater overall fracture displacement (Nagelkerke R2=0.60). Of the cohort, 30.4% (n=34/112) had absent sonographic bridging callus at six weeks in combination with one or more of the ‘high risk’ clinical features. If one was present the nonunion rate was 47.1%, increasing to 60% with two risk factors and 100% when combined with all three. Conclusions. Ultrasound can accurately predict fracture healing at six weeks following a displaced midshaft clavicle fracture. When combined with poor clinical recovery this could be used to target patients for early operative intervention. Declaration of Interest.

Introduction:. Mayo 2A Olecranon fractures are traditionally managed with a tension band wire device (TBW) but locking plates may also be used to treat these injuries. Objectives:. To compare clinical outcomes and treatment cost between TBW and locking plate fixation in Mayo 2A fractures. Methods:. All olecranon fractures admitted 2008–2013 were identified (n=129). Patient notes and radiographs were studied. Outcomes were recorded with the QuickDASH (Disabilies of Arm, Shoulder and Hand) score. Incidence of infection, hardware irritation, non-union, fixation failure and re-operation rate were recorded. Results:. 89 patients had Mayo 2A fractures (69%). Of these patients 64 underwent TBW (n=48) or locking plate fixation (n=16). The mean age for both groups were 57 (15–93) and 60 (22–80) respectively. In the TBW group, the final follow-up QuickDASH was 12.9, compared with 15.0 for the Locking plate group. There was no statistically significant difference between either group (p = 0.312). 19 of the 48 TBW patients had complications (48%). There was 1 infection (2%). 15 cases of metalwork irritation (31%). 1 non-union (2%). 2 fixation failures (4%). 14 of the 48 TBW patients had re-operations (29%). There were 13 removal of metalwork procedures (27%), 1 washout (2%) and 2 revision fixations (4%). There were 0 complications and 0 re-operations in the 16 patients who underwent locking plate fixation. This was statistically significant, (p = 0.003) and (p= 0.015) respectively. TBW costs £7.00 verses £244.10 for a locking plate. Theatre costs were equivalent. A 30 minute day surgery removal of metalwork or similar case costs £1420. In this cohort, when costs of re-operation were included, locking plates were on average £177 less per patient. Conclusions:. Locking plates are superior to TBW in terms of incidence of post-operative morbidity and re-operation rate. Financial savings may be made by choosing a more expensive initial implant

Primary traumatic anterior dislocations of the shoulder are common injuries which are complicated by persistent instability in a high proportion of patients. Surgery is successful and has been well described in the literature. Current controversies centre on the role of open and arthroscopic techniques. We describe the outcomes of a new mini-incision surgical (MIS) technique which was developed within our institution. 27 patients with traumatic shoulder instability (2 bilateral) were prospectively entered into a database between June 1998 and March 2008. The mean age was 31 years and the mean follow up period was 53 months. 29 shoulders underwent diagnostic shoulder arthroscopy and mini-incision surgery using a delto-pectoral approach and 3 bio-absorbable anchors. Patients reported no re-dislocation in 24 shoulders (83%). 5 shoulders, including one with a bony Bankart lesion, re-dislocated with additional trauma. One shoulder required revision to a Bristow-Latarjet. Satisfaction was very good in 16 and good in 9 shoulders (83%). 19 patients had minimal or no pain. 8 patients experienced moderate shoulder pain with the other two complaining of severe pain. QuickDASH scores were encouraging. Our technique combines the ability to appreciate all shoulder pathology arthroscopically with the visualisation gained in open Bankart surgery. Functionally, patients do well. The higher than expected re-dislocation rate is concerning. We advise that long term outcomes are needed

The aim of management of an adult distal humeral fracture is to restore mobility, stability and pain-free elbow function. Good results are usually achieved in the majority of fractures treated with ORIF, but the management of comminuted fractures in elderly, frail patients with osteoporotic bone remains controversial. The literature focuses on elbow replacement if stable internal fixation cannot be achieved, with “bag-of-bones” management now rarely discussed eg. key-note paper - 10 successful cases reported by Brown RF & Morgan RG in 1971 (JBJS 53-B(3):425-428). We present the experience in two units in which conservative management has been actively adopted in selected cases by consultants with a subspecialty interest in the elbow. All patients over the age of 60 with distal humeral fractures (2007 – 2009) who had been treated conservatively were reviewed clinically and radiologically. Duration of follow-up and outcome, including the Oxford and quick DASH scores, were recorded, with the fractures classified using the AO system. There were 25 patients, 19 female and 6 male. 19/25 patients have been successfully treated conservatively with a mean Range Of Movement: Extension/Flexion: 45/125, Pronation/Supination 74/70. Only 5 underwent subsequent total elbow replacement and one delayed ORIF. There is a significant complication rate following surgical treatment with ORIF or elbow replacement in elderly, frail patients, including infection, painful non-union and/or stiffness. We believe that there is a role for initial conservative treatment in selected patients with low, displaced, comminuted humeral fractures in osteoporotic bone. Initial early mobilisation as pain allows can give good functional results without the risks of operation. It does not preclude future surgery if conservative treatment fails, but this is not required in the majority of cases

Objectives

The patient-rated wrist evaluation (PRWE) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire are patient-reported outcome measures (PROMs) used for clinical and research purposes. Methodological high-quality clinimetric studies that determine the measurement properties of these PROMs when used in patients with a distal radial fracture are lacking. This study aimed to validate the PRWE and DASH in Dutch patients with a displaced distal radial fracture (DRF).
