Aims. Hand trauma accounts for one in five of emergency department attendances, with a UK incidence of over five million injuries/year and 250,000 operations/year. Surgical site infection (SSI) in hand trauma surgery leads to further interventions, poor outcomes, and prolonged recovery, but has been poorly researched. Antimicrobial sutures have been recognized by both the World Health Organization and the National Institute for Clinical Excellence as potentially effective for reducing SSI. They have never been studied in hand trauma surgery: a completely different patient group and clinical pathway to previous randomized clinical trials (RCTs) of these sutures. Antimicrobial sutures are expensive, and further research in hand trauma is warranted before they become standard of care. The aim of this protocol is to conduct a feasibility study of antimicrobial sutures in patients undergoing hand trauma surgery to establish acceptability, compliance, and retention for a definitive trial. Methods. A two-arm, multicentre feasibility RCT of 116 adult participants with hand and wrist injuries, randomized to either antimicrobial sutures or standard sutures. Study participants and outcome assessors will be blinded to treatment allocation. Outcome measures will be recorded at baseline (preoperatively), 30 days, 90 days, and six months, and will include SSI, patient-reported outcome measures, and return to work. Conclusion. This will inform a definitive trial of antimicrobial sutures in the hand and wrist, and will help to inform future upper limb trauma trials. The results of this research will be shared with the medical community through high impact publication and presentation. Cite this article: Bone Jt Open 2022;3(7):529–535

Aims. Hand trauma, consisting of injuries to both the hand and the wrist, are a common injury seen worldwide. The global age-standardized incidence of hand trauma exceeds 179 per 100,000. Hand trauma may require surgical management and therefore result in significant costs to both healthcare systems and society. Surgical site infections (SSIs) are common following all surgical interventions, and within hand surgery the risk of SSI is at least 5%. SSI following hand trauma surgery results in significant costs to healthcare systems with estimations of over £450 per patient. The World Health Organization (WHO) have produced international guidelines to help prevent SSIs. However, it is unclear what variability exists in the adherence to these guidelines within hand trauma. The aim is to assess compliance to the WHO global guidelines in prevention of SSI in hand trauma. Methods. This will be an international, multicentre audit comparing antimicrobial practices in hand trauma to the standards outlined by WHO. Through the Reconstructive Surgery Trials Network (RSTN), hand surgeons across the globe will be invited to participate in the study. Consultant surgeons/associate specialists managing hand trauma and members of the multidisciplinary team will be identified at participating sites. Teams will be asked to collect data prospectively on a minimum of 20 consecutive patients. The audit will run for eight months. Data collected will include injury details, initial management, hand trauma team management, operation details, postoperative care, and antimicrobial techniques used throughout. Adherence to WHO global guidelines for SSI will be summarized using descriptive statistics across each criteria. Discussion. The Hand and Wrist trauma: Antimicrobials and Infection Audit of Clinical Practice (HAWAII ACP) will provide an understanding of the current antimicrobial practice in hand trauma surgery. This will then provide a basis to guide further research in the field. The findings of this study will be disseminated via conference presentations and a peer-reviewed publication.

Aims. Plate and screw fixation has been the standard treatment for painful conditions of the wrist in non-rheumatoid patients in recent decades. We investigated the complications, re-operations, and final outcome in a consecutive series of patients who underwent wrist arthrodesis for non-inflammatory arthritis. Patients and Methods. A total of 76 patients, including 53 men and 23 women, with a mean age of 50 years (21 to 79) underwent wrist arthrodesis. Complications and re-operations were recorded. At a mean follow-up of 11 years (2 to 18), 63 patients completed questionnaires, and 57 attended for clinical and radiological assessment. Results. Of the 76 patients, 46 (60.5%) had complications, resulting in 65 re-operations, mainly related to the plate and screws. In the 63 patients who completed the questionnaires, the mean Quick Disabilities of Arm, Shoulder and Hand (QuickDASH) score was 36 (0 to 91), the mean Patient-Rated Wrist and Hand Evaluation (PRWHE) score was 40 (0 to 96), and 14 patients (22%) reported no wrist pain. Grip strength, pinch strength, and pronation and supination were significantly reduced compared with the contralateral forearm. The outcome was worse in patients who had previously undergone surgery to the wrist, and those with complications. A total of 13 are awaiting further re-operations, giving a total re-operation rate of 63% (40/63). Conclusion. We observed complications and re-operations throughout the follow-up period and therefore consider wrist arthrodesis to be more complicated than previously assumed. Many of the patients never got used to or accepted their stiff wrists and reported a substantial reduction in function and residual pain. Motion-sparing surgery should be offered prior to wrist arthrodesis. Cite this article: Bone Joint J 2019;101-B:852–859

Aims. Assessment of bone mineral density (BMD) with dual-energy X-ray absorptiometry (DXA) is a well-established clinical technique, but it is not available in the acute trauma setting. Thus, it cannot provide a preoperative estimation of BMD to help guide the technique of fracture fixation. Alternative methods that have been suggested for assessing BMD include: 1) cortical measures, such as cortical ratios and combined cortical scores; and 2) aluminium grading systems from preoperative digital radiographs. However, limited research has been performed in this area to validate the different methods. The aim of this study was to investigate the evaluation of BMD from digital radiographs by comparing various methods against DXA scanning. Methods. A total of 54 patients with distal radial fractures were included in the study. Each underwent posteroanterior (PA) and lateral radiographs of the injured wrist with an aluminium step wedge. Overall 27 patients underwent routine DXA scanning of the hip and lumbar spine, with 13 undergoing additional DXA scanning of the uninjured forearm. Analysis of radiographs was performed on ImageJ and Matlab with calculations of cortical measures, cortical indices, combined cortical scores, and aluminium equivalent grading. Results. Cortical measures showed varying correlations with the forearm DXA results (range: Pearson correlation coefficient (r) = 0.343 (p = 0.251) to r = 0.521 (p = 0.068)), with none showing statistically significant correlations. Aluminium equivalent grading showed statistically significant correlations with the forearm DXA of the corresponding region of interest (p < 0.017). Conclusion. Cortical measures, cortical indices, and combined cortical scores did not show a statistically significant correlation to forearm DXA measures. Aluminium-equivalent is an easily applicable method for estimation of BMD from digital radiographs in the preoperative setting. Cite this article: Bone Joint Res 2021;10(12):830–839

Aims. Chronic conditions of the wrist may be difficult to manage because pain and psychiatric conditions are correlated with abnormal function of the hand. Additionally, intra-articular inflammatory cytokines may cause pain. We aimed to validate the measurement of inflammatory cytokines in these conditions and identify features associated with symptoms. Patients and Methods. The study included 38 patients (18 men, 20 women, mean age 43 years) with a chronic condition of the wrist who underwent arthroscopy. Before surgery, the Self-Rating Depression Scale (SDS), Hand20 questionnaire and a visual analogue scale (VAS) for pain were used. Cytokine and chemokine levels in the synovial fluid of the wrist were measured using enzyme-linked immunosorbent assays and correlations between the levels with pain were analysed. Gene expression profiles of the synovial membranes were assessed using quantitative polymerase chain reaction. Results. Older patients had high pre-operative Hand20 scores. One-year post-operative Hand20 and VAS scores and pre-operative VAS scores correlated with SDS scores. Post-operative VAS scores negatively correlated with the expression of nerve growth factor and SDS scores positively correlated with the expression of tumour necrosis factor-alpha and negatively correlated with the expression of tumour necrosis factor-converting enzyme. Conclusion. There was a positive correlation between depression and chronic conditions of the wrist. Levels of some cytokines correlate with pain and depression. Additionally, cytokines may be important in the assessment and treatment of chronic conditions of the wrist and depression. Cite this article: Bone Joint J 2016;98-B:961–8

The Motec cementless modular metal-on-metal ball-and-socket wrist arthroplasty was implanted in 16 wrists with scaphoid nonunion advanced collapse (SNAC; grades 3 or 4) and 14 wrists with scapholunate advanced collapse (SLAC) in 30 patients (20 men) with severe (grades 3 or 4) post-traumatic osteoarthritis of the wrist. The mean age of the patients was 52 years (31 to 71). All prostheses integrated well radiologically. At a mean follow-up of 3.2 years (1.1 to 6.1) no luxation or implant breakage occurred. Two wrists were converted to an arthrodesis for persistent pain. Loosening occurred in one further wrist at five years post-operatively. The remainder demonstrated close bone–implant contact. The clinical results were good, with markedly decreased Disabilities of the Arm Shoulder and Hand (DASH) and pain scores, and increased movement and grip strength. No patient used analgesics and most had returned to work. Good short-term function was achieved using this wrist arthroplasty in a high-demand group of patients with post-traumatic osteoarthritis

We investigated the clinical response to arthroscopic synovectomy in patients with undifferentiated chronic monoarthritis (UCMA) of the wrist. Arthroscopic synovectomy was performed on 20 wrists in 20 patients with UCMA of the wrist who had not responded to non-steroidal anti-inflammatory drugs. The mean duration of symptoms at the time of surgery was 4.3 months (3 to 7) and the mean follow-up was 51.8 months (24 to 94). Inflamed synovium was completely removed from the radiocarpal, midcarpal and distal radioulnar joints using more portals than normal. After surgery, nine patients had early remission of synovitis and 11 with uncontrolled synovitis received antirheumatic medication. Overall, there was significant improvement in terms of pain relief, range of movement and Mayo score. Radiological deterioration was seen in five patients who were diagnosed as having rheumatoid arthritis during the follow-up period. Lymphoid follicles and severe lymphocyte infiltration were seen more often in synovial biopsies from patients with uncontrolled synovitis. These results suggest that arthroscopic synovectomy provides pain relief and functional improvement, and allows rapid resolution of synovitis in about half of patients with UCMA of the wrist

Introduction. The wrist is the ”key-stone” of hand function. Painless stability is a prerequisite for the rheumatoid wrist to perform various manual tasks. Synovectomy of the extensor tendons and the wrist joint with a Darrach procedure is offered for painful wrists, which are not controlled by conservative treatment with medication and orthosis. Radiolunate arthrodesis is performed on wrists with an unstable radiocarpal joint and preserved midcarpal joint space. This study describes the long-term (more than 10 years) follow-up of these operative procedures. Materials and methods. The follow-up study was performed on 25 wrists in 25 rheumatoid patients (22 women and 3 men), whose average age was 52 years (range, 33 to 66 years) with an average disease duration of 12 years (range, 1 to 38 years). The average follow-up period was 12. 5 years (range, 10 to 18 years). Five wrists were Larsen-Dale-Eek’s grade II, 14 were grade III, and 6 were grade IV. Depending on the severity of bone destruction, the scaphoid in 6 wrists and the triquetrum in 3 wrists were included in the fusion site. Results. Preoperative pain (88%) and swelling (96%) decreased remarkably at follow-up (12%, 4%). Average grip strength increased significantly from 100mmHg to 140mmHg (p< 0. 01). The total arc of wrist extension/ flexion decreased to two-thirds of the preoperative arc with a major loss in flexion (preop. : 26/28degrees, follow-up: 23/13degrees). The range of forearm rotation increased due to a Darrach procedure. In periodical X-ray assessments of 23 wrists, carpal collapse initially improved following the operation, however, it returned to the preoperative level after 5 years. Ulnar carpal shift improved significantly after the operation (p< 0. 01), and the position remained unchanged over 10 years. In palmar carpal subluxation, no remarkable change was noted. Bone union occurred in 87% of the operated wrists and the remaining 13% had fibrous union. Widening at the lunocapitate joint (> 2mm) was noted in 4 wrists (17%) and progressive instability at the midcarpal joint occurred in one wrist with the mutilating type of disease. Narrowing (< 1mm) was noted in 5 wrists (22%) and 3 wrists were totally fused in the functional position. Discussion. Radiolunate arthrodesis provides good stability with some motion for the moderately deteriorated rheumatoid wrist more than 10 years after the operation, in spite of some radiological progression of the disease. This operation is considered to convert the natural course of the rheumatoid wrist from the unstable form to the stable form

INTRODUCTION. Tuberculosis (TB) is a public health challenge. However, musculoskeletal involvement represents 10–15% of all extrapulmonary cases. Upper extremity involvement is extremely rare. The slow progressive course of clinical symptoms and lack of radiological signs lead to difficulties in establishing early diagnosis. Hence, the patients who have tuberculosis of the wrist are usually misdiagnosed. We report 5 cases of tuberculosis of the wrist seen in our unit from the year 2012 to 2021. METHODS. Cases were retrospectively evaluated on demographics, nature of history, clinical presentation, culture finding, and histopathological findings from 2012 to 2021 at our unit. RESULTS. A total of 5 cases were evaluated retrospectively. Three patients were more than 60 years old and two were less than 30 years old. Four of the patients presented with wrist swelling 2 of them had wrist pain and only 1 patient had discharge from the wound. The duration of the symptoms ranges from 2 months to 3 years. Only one of the patients had a history of pulmonary TB contact whereas the others didn't. All patients underwent surgery. All of the patients had positive cultures for Mycobacterium tuberculosis complex and histopathological examination showed necrotizing granulomatous inflammation from specimens taken intraoperatively, which confirmed the diagnosis of tuberculosis of the wrist. DISCUSSIONS. Our cases show that the common presentation of tuberculosis of the wrist was comparable to other literature. Most of the patients presented with chronic wrist swelling with or without wrist pain. The diagnosis of the disease was delayed an average of 10 - 12 months from symptoms onset to diagnosis. S. Bayram et al reported a case where the diagnosis was made 45 months later. Due to its rarity, it often is misdiagnosed, resulting in delays in the proper treatment. CONCLUSION. The diagnosis of the TB wrist remains difficult because of insidious and non-specific. presentation. However, early diagnosis is essential to avoid delays in treatment and complications. Hence, chronic wrist pain, and swelling with or without unexplained bone erosion around the wrist area must be highly suspected of being osteoarticular tuberculosis

Aims. Wrist arthroscopy is a standard procedure in hand surgery for diagnosis and treatment of wrist injuries. Even though not generally recommended for similar procedures, general administration of perioperative antibiotic prophylaxis (PAP) is still widely used in wrist arthroscopy. Methods. A clinical ambispective dual-centre study was performed to determine whether PAP reduces postoperative infection rates after soft tissue-only wrist arthroscopies. Retrospective and prospective data was collected at two hospitals with departments specialized in hand surgery. During the study period, 464 wrist arthroscopies were performed, of these 178 soft-tissue-only interventions met the study criteria and were included. Signs of postoperative infection and possible adverse drug effects (ADEs) of PAP were monitored. Additionally, risk factors for surgical site infection (SSIs), such as diabetes mellitus and BMI, were obtained. Results. The overall infection rate of SSI was zero. Neither in the PAP group (n = 69) nor in the control group (n = 109) were signs of postoperative infection observed. Observed symptoms of ADEs were three-times higher in the PAP group when compared to the control-group (16.3 vs 5.5%; p = 0.043). No major ADEs were observed, but one in ten patients in the PAP group reported mild to severe intestinal or hypersensitivity symptoms. Conclusion. We demonstrate that the number needed to treat (NNT) with PAP to prevent one postoperative infection in soft-tissue arthroscopies of the wrist is > 109. Conversely, symptoms of ADEs were reported by one out of ten patients given PAP. Considering the high NNT to prevent postoperative infection and the large number of ADEs caused by PAP, we recommend not to use PAP routinely in soft-tissue arthroscopies of the wrist. Subsequent large-scale studies should be conducted to substantiate these results. Cite this article: Bone Jt Open 2023;4(4):219–225

Introduction. The wrist arthroscopy has been performed since 1979. With the advances in technology and surgical expertise, wrist arthroscopy has become third commonest procedure after knee and shoulder joint. Wrist arthroscopy has become a gold standard for diagnosing TFCC pathologies and other intercarpal disorders. Our aim was to compare the clinical, MRI and arthroscopic findings while treating various wrist pathologies. Materials/Method. In retrospective trial, 30 patients (19 male and 11 female) with clinical evidence of wrist lesions were evaluated with MRI followed by wrist arthroscopy. The mean age of the patients at the time of outpatient appointment was 44 years with an average waiting time of 6.6 months. Inclusion criteria: all patients undergoing wrist surgery. Exclusion criteria: septic arthritis, acute distal radius fractures. Kappa analysis was used to compare the three methods of wrist pathology assessment. The total 30 patients were assessed for clinical findings, MRI report and corresponding arthroscopic findings. Results. According to the clinical findings, 22 patients (68% of all patients) were diagnosed with suspected TFCC injury. In 21 patients, the MRI showed TFCC tear (partial to complete) and this was confirmed by arthroscopy in 22 patients. There was a correlation of clinical, MRI and arthroscopy in detecting TFCC lesions in 95% cases. Sensitivity 93%, specificity 90%, positive predictive value 89% and negative predictive value 94%. The Scapho-lunate ligament tear was suspected in 8 (28% of all patients). In 6 patients, MRI showed scapho-lunate tear and this was confirmed by wrist arthroscopy in 10 patients. Correlation with wrist arthroscopy was 80%, sensitivity 94%, specificity 92%, positive predictive value 90% and negative predictive value 93%. 15 patients (50% of all patients) showed signs of moderate to severe cartilage wear and 12 patients had confirmation with MRI. Correlation with wrist arthroscopy was 75%, Sensitivity 90%, Specificity 91%, positive predictive value 89% with negative predictive value 92%. However clinical examination and MRI had poor correlation with wrist arthroscopy in diagnosing synovitis. Discussion. The MRI and wrist arthroscopy has fair correlation, though MRI sensitivity approaches that of arthroscopy, it cannot replace it at the moment. However, it is a potent additional tool for wrist diagnosis if intra-articular contrast is used. It can facilitate diagnosis and indications for surgery of the wrist. It may make arthroscopic and more invasive interventions for diagnostic purposes avoidable in future. Our results showed clinical examination is crucial for diagnosing wrist pathologies, MRI can be used as an adjunct but the wrist arthroscopy still remains the gold standard tool for diagnosis and therapeutic interventions

Aim. There are no definitive criteria for the definition of osteomyelitis in the hand and wrist and published case series are small. It remains a relatively uncommon, but difficult to treat problem. We present a series of 30 cases from 2016 to 2021 from a tertiary referral centre. We propose that the principles of thorough surgical debridement, dead space management, skeletal stabilisation and culture driven antibiotic therapy are the key to management of osteomyelitis in the hand and wrist. In addition, we show how these basic principles can be used for both functional and aesthetic impact for the wrist and digits with illustrated cases. Methods. We conducted a retrospective chart review over a 6 year period and recorded the site of the infection, the soft tissue and bony management, whether antibiotic eluting bone filler was used, the isolated bacterial species, the number of surgical procedures undertaken to treat the infection and the success rate for clearing the infection. Results. 17/30 cases had pre-existing metalwork in-situ. There were 19 phalangeal/metacarpal infections and 11 carpal infections. 24 patients had native joint involvement. A drug eluting bone void filler was used in 23/30 cases in order to manage the dead space. In 7/30 cases had polymicrobial organisms isolated, 15/30 had only one organism cultured. The most common organism cultured was Staphylococcus aureus. Complete resolution of osteomyelitis or joint infection was achieved in 29/30 cases with follow up ranging from six months to six years. 2/30 cases required thorough debridement of the distal phalanx; bone void filler provided an aesthetically optimal result to improve fingertip contour whilst managing the dead space. Conclusion. Osteomyelitis of the hand and wrist is optimally managed with thorough surgical debridement, dead space management with a drug eluting bone void filler, skeletal stabilisation and culture directed antibiotic therapy. In addition, the bone void filler provides pulp support and improves the aesthetic contour of fingertips in which distal phalangeal osteomyelitis was successfully treated

SARS-CoV-2 emerged in Wuhan, China in December 2019 causing pneumonia and resulting in a pandemic, commonly known as COVID-19. This pandemic led to significant changes to our daily lives due to restrictions, such as social distancing, quarantining, stay at home orders and closure of restaurants and shops among other things. The psychological effects of this uncertainty as well as of these changes to our lives have been shown to be significant. This study is a prospective study investigating the mental effects of the pandemic on hand and wrist patients seen in our clinic during this pandemic. A prospective database on wrist pain was used to identify patients seen in our hand clinic from January 1, 2018 to December 10, 2021. All participants had been diagnosed with either radial sided wrist pain or ulnar side wrist pain. The Center for Epidemiological Studies Depression (CES-D) Scale was used to assess the mental health of our participants before and during this pandemic. An independent samples t-test was used to compare the scores of the 2 groups. A total of 437 CES-D questionnaires were collected during this period. 118 of them belonging to the pandemic group and 319 to the pre-pandemic group. A difference (p < 0 .05) in the CES-D score was observed between the pre-pandemic and during pandemic groups. The mean score for the pre-pandemic group was found to be 9.23 (8.94) and 12.81 (11.45) for the pandemic group. However, despite the increase in score, it didn't exceed the cut off score of 16 or greater used to assess depression. Our results indicate that there was a slight increase in score for depression in hand and wrist patients, but not above the cut off level of 16 to be of a significant risk for depression. Other global studies have shown an increase in depression in the general public. Our mild results might be attributed to the fact that British Columbia did not implement severe restrictions compared to other countries or regions, i.e no stay at home orders. Additionally, our study population was skewed and included more middle age and older patients compared to younger ones and age might be a factor in keeping the score down

Abstract. Objectives. Falling studies have been conducted in controlled environments but not in field studies for ethical reasons; this limits the validity and applicability of previous studies. We performed field studies on existing YouTube © videos of skateboarders falling. The aims were to measure the wrist angle at impact on videos of real unprotected falls and to study the dynamics of the upper limbs when falling. Methods. Youtube © videos of skateboarders falling were studied assessing the direction of the fall, the positions of both upper limbs and especially the wrists on impact. This study would not be ethical by other means. Results. In study one (the more quantitative study) there were 48 men and 50 falls. The mean elbow flexion was 300 (range 00 to 800) and the mean maximal wrist extension was 800 (range 500 to 1100). The secondary wrist extended less or the same in > 90%. The second wrist only one (of 31) extended > 900 which should minimise the risk of toppling. Falls onto only one wrist gave significantly greater maximal wrist extension. In the second more qualitative study we observed the “upper limb falling reflex” where the response to falling is for the upper limb(s) to align with the direction of falling of the body with the elbow mostly but not fully extended. Initially the wrists extend c. 400–500 with the fingers held mildly flexed. Immediately before impact the fingers hyper-extend with some compensatory wrist flexion to c. 300. The fingertips impact the ground first followed by the hand. Conclusion. These studies confirm wrist extension at impact around 800 but the wrist(s) may hyper-extend risking toppling. Falls on both wrists minimise the risk of toppling. The “upper limb falling reflex” is defined; it is a rapid dynamic response leading to the fingers impacting the ground first on falling.

Aim: To assess the functional and radiological outcome of AO wrist Arthrodesis using the AO wrist fusion plate. Method: An 8 year, independent, retrospective, radiological and functional review was performed using The DASH (Disabilities of the Arm, Shoulder and Hand questionnaire) and the Buck-Gramcko/Lohmann outcome scores. Results: Twenty-eight patients were reviewed. The two scoring systems correlated consistently in regards to the functional outcome. However, patients with systemic disease experienced problems completing the DASH questionnaire. Mono-articular arthritis was associated with an excellent/good outcome in 95% of cases. Results for patients with systemic disease were markedly worse. There was one case of plate breakage associated with a delayed union of the second MCP joint. There was a 100% union rate, no significant post-operative infections and no tendon ruptures. Conclusion: The short to mid term clinical outcomes for the AO wrist fusion plate are encouraging and its use can be recommended in a variety of wrist pathologies

Treating 10 consecutive patients requiring wrist arthrodesis, we assessed the effectiveness of a titanium plate specifically designed by Hill Hastings for wrist arthrodesis. It appeared to call for little or no postoperative casting and to promise an early return to functionality. We secured the plate to the third metacarpal and the radius and used autologous bone graft taken from their iliac crest. Length of time immobilisation, time to union, overall functional results and patient satisfaction were recorded. In all 10 patients clinical and radiological union occurred in 8 to 12 weeks. Four patients had no postoperative immobilisation and six had a Litecast. Correctly applied, the pre-contured plate produced a consistently satisfactory position of fusion. One patient had a small area of wound skin necrosis in a pre-existing transverse scar over the dorsum of the wrist, but this healed. The carpometacarpal joint is included in this fusion, which requires a longer longitudinal incision than some other wrist fusion techniques. However, patient satisfaction was high

The aim of the study was to compare the radiological findings of wrist arthrogram with wrist arthroscopy. This allowed us to establish the accuracy (sensitivity, specificity) of MRI arthrogram as a diagnostic tool. Thirty patients (20 female and 10 male) have undergone both wrist MRI arthrogram and wrist arthroscopy over the last 3 years at Macclesfield District General Hospital. The mean age at arthrogram was 42.4 years with an average 6.7 month gap between the two procedures. The MRI arthrogram was reported by a consultant radiologist with an interest in musculoskeletal imaging and the arthrosopies performed by two upper limb surgeons. Patients undergoing both procedures were identified. The arthrogram reports and operation notes were examined for correlation. Three main areas of pathology were consistently examined: TFCC (triangular fibrocartilage complex), scapholunate and lunatotriquetral ligament tears. The sensitivity and specificity of arthrogram was calculated for each. Other areas of pathology were also noted. In the case of TFCC tears MRI arthrogram had a 92.3% sensitivity and 54.6% specificity. The lunatotriquetral ligament examination with this technique was 100% sensitivity and specificity. However for scapholunate ligament tears it only had 50% sensitivity and 77.8% specificity. Wrist arthrogram and arthroscopy are both invasive techniques and equally time consuming. In cost terms the arthrogram remains cheaper but is superseded by arthroscopy as it is both diagnostic and therapeutic

Purpose: To review a clinical series of patients who have had the SLAC (scapho-lunate advanced collapse) procedure. Method: 50 patients with degenerative disorders of the wrist managed by a single surgeon using a single technique. The technique involved excision of the scaphoid and radial styloidectomy. Midcarpal arthrodesis was performed, and was stabilised with staples. The patients were prospectively followed for two years. Results: The majority of patients were satisfied with their outcome and their pain had decreased. Pre-operative flexion/extension was 39 degrees/38 degrees and post-operatively was 32 degrees/35 degrees. The average grip strength did not change. Conclusion: The SLAC wrist procedure is a useful technique for patients who have localised degenerative arthritis of the wrist

The wrist is a complex joint involving many small bones and complicated kinematics. It has, therefore, been traditionally difficult to image and ascertain information about kinematics when making a diagnosis. Although MRI and fluoroscopy have been used, they both have limitations. Recently, there has been interest in the use of 4D-CT in imaging the wrist. This review examines the literature regarding the use of 4D-CT in imaging the wrist to assess kinematics and its ability to diagnose pathology. Some questions remain about the description of normal ranges, the most appropriate method of measuring intercarpal stability, the accuracy compared with established standards, and the place of 4D-CT in postoperative assessment.

Pain and disability following wrist trauma are highly prevalent, however the mechanisms underlying painare highly unknown. Recent studies in the knee have demonstrated that altered joint contact may induce changes to the subchondral bone density and associated pain following trauma, due to the vascularity of the subchondral bone. In order to examine these changes, a depth-specific imaging technique using quantitative computed tomography (QCT) has been used. We've demonstrated the utility of QCT in measuring vBMD according to static jointcontact and found differences invBMD between healthy and previously injured wrists. However, analyzing a static joint in a neutral position is not necessarily indicative of higher or lower vBMD. Therefore, the purposeof this study is to explore the relationship between subchondral vBMDand kinematic joint contact using the same imaging technique. To demonstrate the relationship between kinematic joint contact and subchondral vBMDusing QCT, we analyzed the wrists of n = 10 participants (n = 5 healthy and n = 5 with previous wrist trauma). Participantsunderwent 4DCT scans while performing flexion to extension to estimate radiocarpal (specifically the radiolunate (RL) and radioscaphoid (RS)) joint contact area (JCa) between the articulating surfaces. The participantsalso underwent a static CT scan accompanied by a calibration phantom with known material densities that was used to estimate subchondral vBMDof the distal radius. Joint contact is measured by calculatinginter-bone distances (mm2) using a previously validated algorithm. Subchondral vBMD is presented using mean vBMD (mg/K2HPO4) at three normalized depths from the subchondral surface (0 to 2.5, 2.5 to 5 and 5 to 7.5 mm) of the distal radius. The participants in the healthy cohort demonstrated a larger JCa in the RS joint during both extension and flexion, while the trauma cohort demonstrated a larger JCa in the RL during extension and flexion. With regards to vBMD, the healthy cohort demonstrated a higher vBMD for all three normalized depths from the subchondral surface when compared to the trauma cohort. Results from our preliminary analysis demonstrate that in the RL joint specifically, a larger JCa throughout flexion and extension was associated with an overall lower vBMD across all three normalized layers. Potential reasoning behind this association could be that following wrist trauma, altered joint contact mechanics due to pathological changes (for example, musculoskeletal trauma), has led to overloading in the RL region. The overloading on this specific region may have led to a decrease in the underlying vBMD when compared to a healthy wrist. However, we are unable to conclude if this is a momentary decrease in vBMD that could be associated with the acute healing phase following trauma given that our analysis is cross-sectional. Therefore, future work should aim to analyze kinematic JCa and vBMD longitudinally to better understand how changes in kinematic JCa over time, and how the healing process following wrist trauma, impacts the underlying subchondral bone in the acute and longitudinal phases of recovery

Aims. To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour. Methods. A total of 40 patients suffering from non-rheumatoid wrist arthritis were enrolled in a randomized controlled trial comparing the ReMotion and Motec TWAs. Patient-rated and functional outcomes, radiological changes, blood metal ion levels, migration measured by model-based radiostereometric analysis (RSA), bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), complications, loosening, and revision rates at two years were compared. Results. Patient-Rated Wrist and Hand Evaluation (PRWHE) scores, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire (QuickDASH) scores, and pain improved similarly and significantly in both groups. Wrist motion improved significantly in the Motec group only, and forearm rotation in the ReMotion group only. Cobalt (Co) and chromium (Cr) blood ion levels were significantly higher in the metal-on-metal (MoM) Motec group than in the metal-on-polyethylene (MoP) ReMotion group. Mean total translation was 0.65 mm (95% confidence interval (CI) 0.26 to 1.12) and 0.27 mm (95% CI 0.14 to 0.47) for the ReMotion carpal and radial components, and 0.32 mm (95% CI 0.22 to 0.45) and 0.26 mm (95% CI 0.20 to 0.34) for the Motec metacarpal and radial components, respectively. Apart from dorsal and volar tilts, which were significantly higher for the radial ReMotion than for the Motec component, no significant differences in absolute migration occurred. BMD around the radial components never returned to baseline. Almost one-third of patients required reoperation due to complications. Two ReMotion implants were revised to Motec TWAs due to carpal component loosening, and three Motec MoM articulations were revised to metal-on-polyether ether ketone due to painful synovitis. Conclusion. Both implants provided matched function and were stable at short-term follow-up, but with a high complication rate. This procedure should be restricted to specialist centres undertaking prospective analysis until its role is clarified. Cite this article: Bone Joint J 2022;104-B(10):1132–1141

Arthritis of the wrist is a painful disabling condition that has various causes and presentations. The traditional treatment has been a total wrist fusion at a price of the elimination of movement. However, forms of treatment which allow the preservation of movement are now preferred. Modern arthroplasties of the wrist are still not sufficiently robust to meet the demands of many patients, nor do they restore normal kinematics of the wrist. A preferable compromise may be selective excision and partial fusion of the wrist using knowledge of the aetiology and pattern of degenerative change to identify which joints can be sacrificed and which can be preserved. . This article provides an overview of the treatment options available for patients with arthritis of the wrist and an algorithm for selecting an appropriate surgical strategy.

Physical examination is critical to formation of a differential diagnosis in patients with ulnar-sided wrist pain. Although the specificity and sensitivity of some of those tests have been reported in the literature, the prevalence of positive findings of those provocative maneuvers has not been reported. The aim of the study is to find the prevalence of positive findings of the most commonly performed tests for ulnar sided wrist pain in a population presenting to UE surgeon clinics, and to correlate those findings with wrist arthroscopy findings. Patients with ulnar sided wrist pain were identified from a prospective database of patients presented with wrist pain from September 2014. Prevalence of positive findings for the following tests were gathered: ECU synergy test, ECU instability test (Ice cream and Fly Swatter), Lunotriquetral ballottement, Kleinman shear, triquetrum tenderness, triquetrum compression test, triquetral-hamate tenderness, pisotriquetral shuck test, ulnar fovea test, ulnocarpal impaction (UCI) maneuver, UCI maneuver with fovea pressure (ulnar carpal plus test), piano key sign. A subgroup was then created for those who underwent wrist arthroscopy, and analysis of the sensitivities, the specificities and the predictive values of these provocative tests was carried out with correlation to arthroscopic finding. Prevalence of ECU instability tests was t 1.13% (ice cream scoop) and 1.5% (fly swatter). Lunotriquetral ballottement test's positive findings range from 4.91% (excessive laxity) to 14.34% (pain reproducing symptoms. The Kleinman shear test yielded pain in 13.58% of patients, and instability in only 2.26%. Triquetrum compression test reproduces pain in 32.83% of patients, and triquetral-hamate tenderness reproduced pain in 13.21%. Pisotriquetral grind test yields 15.85% positive findings for pain, and 10.57% for crepitus with radioulnar translation. The ulnar fovea test revealed pain in 69.05% of cases. The UCI maneuver yielded pain in 70.19%. The UCI maneuver plus ulnar fovea test reproduced pain in 80.38% of cases. Finally, the piano key sign yields positive finding in 2.64% of cases. For patients who underwent surgery, sensitivities, specificities and predictive values were calculated based on arthroscopic findings. The lunotriquetral ballottement test has 59.6% sensitivity, 39.6% specificity, 20.3% positive predictive value and 85.4% negative predictive value. The sensitivity of Kleinman test was 62.4%, the specificity was 41.3%, the positive predictive value was 23.5%, and the negative predictive value was 83.2%. The sensitivity of fovea test was 94.3%, the specificity was 82.5%, the positive predictive value was 89.5% and the negative predictive value was 92.3%. The UCI maneuver plus ulnar fovea test has 96.5% sensitivity, 80.7% specificity 86.4% positive predictive value, and 95.3% negative predictive value. Among the provocative tests, the prevalence of positive findings is low in the majority of those maneuvers. The exceptions are the fovea test, the UCI maneuver, and the UCI plus maneuver. With regard to the sensitivity and the specificity of those tests, the current study reproduces the numbers reported in the literature. Of those patients who underwent wrist arthroscopy, the tests are better at predicting at the absence of injury rather than at predicting its presence

Purpose: In skeletally immature children with acceptably angulated (< = 15 degrees angular deformity at presentation) distal radius and/or ulnar fractures, to determine if a pre-fabricated wrist splint is at least as effective as a cast. The primary outcome was recovery of physical function six weeks after the injury as measured by the validated Activities Scale for Kids. Secondary objectives included determining differences in angulation of fracture, wrist range of motion, wrist strength, pain with movement, return to baseline activities, and patient preferences at six weeks. Method: A randomized controlled, non-inferiority, single (evaluator) blinded, single-centre trial in a tertiary care pediatric emergency department. Minimal required sample size of 76 patients with was based on testing the null hypothesis (H0) that the brace is 7% less effective at the 2.5% level. Physical function was tested by a t-test for a non-zero difference. For the other outcomes, proportions and means were compared with the Fisher Exact and Student s t-test, respectively. Results: Of the 100 randomized patients, 3 were excluded due to non-eligibility on radiographic review. 93 of the 97 completed full clinical, radiographic, and patient determined followup. ASK scores at six weeks were 92.8 in the splint group and 91.4 in the cast group, neither clinically nor statistically significantly different. Among patients treated in a cast, the average angular deformity at followup was 11.0 degrees and compared with an average of 6.6 degrees angulation among patients treated in a splint (p=.02, t-test). These groups were equal at baseline, with an average of 7.5 degrees of angulation in the cast group and 6.7 degrees in the splint group. Complications did not differ between groups, nor did range of motion with the exception that pronation was slightly better (84 versus 74 degrees) in the splint group at the end of treatment. No patient required any operative procedure. Parents preferred splinting over casting (p< 0.001) and children preferred splinting over casting (p=0.028). Conclusion: Splinting was non-inferior to casting, and in fact may be superior to casting, for maintaining the position of a minimally displaced distal radial metaphyseal fracture. Significance: The benefits of splinting over casting have been previously established for undisplaced distal radius and ulnar fractures (Plint), this is the first study which extends these benefits to the large group of children with minimally displaced distal radius fractures. Splint treatment simplifies care for children, reduces cost, and improves short term outcomes

The aims of this study in relation to distal radius fractures were to determine (1) the floor and ceiling effects for the QuickDASH and PRWE, (2) the floor and ceiling effects when defined to be within the minimal clinically important difference (MCID) of the minimal or maximal scores, (3) the degree to which patients with a floor or ceiling effect felt that their wrist was ‘normal’, and (4) patent factors associated with a floor or ceiling effect. A retrospective cohort study of patients sustaining a distal radius fracture during a single year was undertaken. Outcome measures included the QuickDASH, PRWE, EQ-5D-3L and normal wrist score. There were 526 patients with a mean age of 65yrs and 77% were female. Most patients were managed non-operatively (73%, n=385). The mean follow-up was 4.8yrs. A ceiling effect was observed for both the QuickDASH (22.3%) and PRWE (28.5%). When defined to be within the MCID of the best score, the effect increased to 62.8% for the QuickDASH and 60% for PRWE. Patients that achieved the best functional outcome according to the QuickDASH and PRWE felt their wrist was only 91% and 92% normal, respectively. Sex (p=0.000), age (p=0.000), dominant wrist injury (p=0.006 for QuickDASH and p=0.038 for PRWE), fracture type (p=0.015), and a better health-related quality of life (p=0.000) were independently associated with achieving a ceiling score. The QuickDASH and PRWE demonstrated ceiling effects following a distal radius fracture. Patients achieving ceiling scores did not consider their wrist to be ‘normal’ for them
