Aims. Although chondrosarcomas (CSs) display true malignant features, including local recurrence (LR) and metastases, their behaviour in the hands and feet is thought to differ from that in other parts of the axial and appendicular skeleton by having a lower metastatic potential. The purpose of this study was to investigate the disease-specific and surgical factors that affect the local and systemic prognosis of CS of the hands and feet. Methods. A multicentre retrospective study was carried out at two tertiary sarcoma centres. A database search identified all patients with a CS treated between January 1995 and January 2018. There were 810 CSs of which 76 (9.4%) were located in the fingers, toes, metacarpals, and metatarsal bones. Results. The median age of the study population was 55 years (36 to 68) with a median follow-up of 52 months (22 to 87) months. Overall, 70% of the tumours were in the hand (n = 54) and 30% in the foot (n = 22). Predictors for LR were margin (p = 0.011), anatomical location (p = 0.017), and method of surgical management (p = 0.003). Anatomical location (p = 0.026), histological grade between 1 and 3 (p = 0.004) or 2 and 3 (p = 0.016), and surgical management (p = 0.001) were significant factors for LR-free survival. Disease-specific survival was affected by histological grade (p < 0.001), but not by LR (p = 0.397). Conclusion. Intralesional curettage of a low-grade CS is associated with an increased risk of LR, but LR does not affect disease-specific survival. Therefore, for low-grade CSs of the hands and feet, surgical management should aim to preserve function. In grade 2 CS, our study did not show any decreased disease-specific survival after recurrence; however, we suggest a more aggressive surgical approach to these tumours to prevent local recurrence, especially in the metacarpal and metatarsal bones. In high-grade tumours, the incidence of progressive disease is high and, therefore, the treatment of the primary tumour should be aggressive where possible, and patients observed closely for the development of metastatic disease.

Giant cell tumours (GCTs) of the small bones of the hands and feet are rare. Small case series have been published but there is no consensus about ideal treatment. We performed a systematic review, initially screening 775 titles, and included 12 papers comprising 91 patients with GCT of the small bones of the hands and feet. The rate of recurrence across these publications was found to be 72% (18 of 25) in those treated with isolated curettage, 13% (2 of 15) in those treated with curettage plus adjuvants, 15% (6 of 41) in those treated by resection and 10% (1 of 10) in those treated by amputation. We then retrospectively analysed 30 patients treated for GCT of the small bones of the hands and feet between 1987 and 2010 in five specialised centres. The primary treatment was curettage in six, curettage with adjuvants (phenol or liquid nitrogen with or without polymethylmethacrylate (PMMA)) in 18 and resection in six. We evaluated the rate of complications and recurrence as well as the factors that influenced their functional outcome. At a mean follow-up of 7.9 years (2 to 26) the rate of recurrence was 50% (n = 3) in those patients treated with isolated curettage, 22% (n = 4) in those treated with curettage plus adjuvants and 17% (n = 1) in those treated with resection (p = 0.404). The only complication was pain in one patient, which resolved after surgical removal of remnants of PMMA. We could not identify any individual factors associated with a higher rate of complications or recurrence. The mean post-operative Musculoskeletal Tumor Society scores were slightly higher after intra-lesional treatment including isolated curettage and curettage plus adjuvants (29 (20 to 30)) compared with resection (25 (15 to 30)) (p = 0.091). Repeated curettage with adjuvants eventually resulted in the cure for all patients and is therefore a reasonable treatment for both primary and recurrent GCT of the small bones of the hands and feet.

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. The aim of this study was to develop a core outcome set of what to measure in all future clinical research on hand fractures and joint injuries in adults. Methods. Phase 1 consisted of steps to identify potential outcome domains through systematic review of published studies, and exploration of the patient perspective through qualitative research, consisting of 25 semi-structured interviews and five focus groups. Phase 2 involved key stakeholder groups (patients, hand surgeons, and hand therapists) prioritizing the outcome domains via a three-round international Delphi survey, with a final consensus meeting to agree the final core outcome set. Results. The systematic review of 160 studies identified 74 outcome domains based on the World Health Organization International Classification of Functioning, Disability, and Health. Overall, 35 domains were generated through thematic analysis of the patient interviews and focus groups. The domains from these elements were synthesised to develop 37 outcome domains as the basis of the Delphi survey, with a further four generated from participant suggestions in Round 1. The Delphi survey identified 20 outcome domains as ‘very important’ for the core outcome set. At the consensus meeting, 27 participants from key stakeholder groups selected seven outcomes for the core outcome set: pain/discomfort with activity, pain/discomfort with rest, fine hand use/dexterity, self-hygiene/personal care, return to usual work/job, range of motion, and patient satisfaction with outcome/result. Conclusion. This set of core outcome domains is recommended as a minimum to be reported in all clinical research on hand fractures and joint injuries in adults. While this establishes what to measure, future work will focus on determining how best to measure these outcomes. By adopting this patient-centred core outcome set, consistency and comparability of studies will be improved, aiding meta-analysis and strengthening the evidence base for management of these common and impactful injuries.

In the field of hand surgery, physicians are working to improve patient satisfaction by offering several minor procedures in the physician's office via the WALANT method. We seek to investigate the degree of patient satisfaction, out of pocket cost, convenience and comfort experienced with in-office hand procedures. A ten question survey consisting of a ten-point Likert scale of agreement and questions asking for a numerical answer was administered via phone call to 33 patients treated with minor hand operations in the office setting in the United States. There were 18 male and 15 female respondents with an average age of 65.59±12.64 years. Respondents underwent procedures including trigger finger release (18), needle aponeurotomy (7), and other minor hand operations. Survey responses indicated strong agreement with questions 1-3 and 6–8, with responses averaging 9.60±0.23 in these positive metrics. Questions 4 and 5, which asked whether the surgery and recovery period were painful, respectively, averaged 2.65±0.49, indicating a mild level of disagreement that either was “painful”. Additionally, most patients responded that they did not take time off work (12) or are not currently employed (11). Other respondents (3) reported taking between one to five days off work post-operatively. 27 respondents also reported an out of pocket cost averaging $382±$976, depending on insurance coverage. Patients reported a small degree of pain in the operative and post-operative period, a high degree of comfort and convenience and a high degree of satisfaction. Likewise, the patient-reported out of pocket cost was far lower than comparable surgical costs in alternate settings. These results support the use of in-office procedures for minor hand surgeries from a patient perspective and indicate a nearly universal intent to repeat any future hand operations in the office setting

In-office surgeries have the potential to offer high quality medical care in a more efficient, cost-effective setting than outpatient surgical centers for certain procedures. The primary concerns with operating on patients in the office setting are insufficient sterility and lack of appropriate resources in case of excessive bleeding or other surgical complications. This study serves to investigate these concerns and determine whether in-office hand surgeries are safe and clinically effective. A retrospective review of patients who underwent minor hand operations in the office setting between December 2020 and December 2021 was performed. The surgical procedures included in this analysis are needle aponeurotomy, trigger finger release, mass/foreign body removal and reduction of hand/wrist fracture with or without percutaneous pinning. No major complications requiring extended observation or hospital admission occurred. 122 of the 132 patients (92.4%) were successfully treated with no complications and only mild symptoms within one month of surgery. Five patients (3.8%) returned to the office for pain, inflammation and/or stiffness of the affected finger, with two of the five returning due to osteoarthritis and/or pseudogout flare-ups. Five additional patients returned due to incomplete treatment with continued presence of Dupuytren's contracture (3), trigger finger (1) or infected foreign body (1). One patient (0.8%) developed infection, due to incomplete removal of an infected foreign body, which was subsequently treated with antibiotics and complete foreign body removal. The absence of major complications and high success rate for minor hand procedures shows the high degree of safety and efficacy which can be achieved via the in-office setting for select procedures. While proper patient selection is key, our result shows the in-office procedure room setting can offer the necessary elements of sterility and hemostatic support for several common hand surgeries

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

Aims. The aims of this study were to describe the epidemiology of metacarpal shaft fractures (MSFs), assess variation in treatment and complications following standard care, document hospital resource use, and explore factors associated with treatment modality. Methods. A multicentre, cross-sectional retrospective study of MSFs at six centres in the UK. We collected and analyzed healthcare records, operative notes, and radiographs of adults presenting within ten days of a MSF affecting the second to fifth metacarpal between 1 August 2016 and 31 July 2017. Total emergency department (ED) attendances were used to estimate prevalence. Results. A total of 793 patients (75% male, 25% female) with 897 MSFs were included, comprising 0.1% of 837,212 ED attendances. The annual incidence of MSF was 40 per 100,000. The median age was 27 years (IQR 21 to 41); the highest incidence was in men aged 16 to 24 years. Transverse fractures were the most common. Over 80% of all fractures were treated non-surgically, with variation across centres. Overall, 12 types of non-surgical and six types of surgical treatment were used. Fracture pattern, complexity, displacement, and age determined choice of treatment. Patients who were treated surgically required more radiographs and longer radiological and outpatient follow-up, and were more likely to be referred for therapy. Complications occurred in 5% of patients (39/793). Most patients attended planned follow-up, with 20% (160/783) failing to attend at least one or more clinic appointments. Conclusion. MSFs are common hand injuries among young, working (economically active) men, but there is considerable heterogeneity in treatment, rehabilitation, and resource use. They are a burden on healthcare resources and society, thus further research is needed to optimize treatment. Cite this article: Bone Jt Open 2024;5(8):652–661

Both intrinsic and extrinsic hand muscles contribute to finger flexion; however there are different ways in which individuals can flex their fingers. Due to different muscle insertions, it is possible to distinguish the mechanical effect of intrinsic muscles from extrinsic muscles. The aim of this observational study was to investigate the degree to which individuals in the population rely on either their intrinsic or extrinsic hand muscles. A high frequency camera was used to record the hands of 31 healthy participants, aged between 18 to 40, while they made a fist repeatedly. The hands were placed on a horizontal plane and the video was taken from the ulnar side, aligned horizontally with the hand. The maximum vertical distance between the fingertip and the distal palmer creases (XY) was recorded using WIN analyze 3D software. Three examiners independently analysed the videos and classified them into intrinsic dominant, extrinsic dominant or a mixed pattern. A t-test was performed on the XY values for the three different categories. The XY height difference between the intrinsic and extrinsic groups were statistically significant (P=0.001). The XY of mixed and intrinsic was also statistically significant (p=0.012) but not for mixed and extrinsic (p=0.46). Assessment of time when movement starts at each individual joint showed significant difference with intrinsic predominant moving the MCPJ before IPJ and extrinsic dominant individual moving their IPJ before MCPJ. This study shows that there is a difference in hand muscle dominance between individuals. More importantly it shows that there are individuals who rely on their intrinsic hand muscles more than their extrinsic muscles

Aims. The aim of this study was to evaluate the need for hand trauma services during the COVID-19 pandemic lockdown, specifically related to surgical requirements. This will provide useful information for planning and resource allocation in the event of any further lockdown. Methods. A prospective analsysis of all patients attending our hand trauma unit throughout the UK COVID-19 lockdown period (24 March to 10 May 2020) was carried out. Prospectively collected departmental data from the same period in 2019 was obtained and reviewed for comparison. The number of patients attending clinic, undergoing surgery, the type of surgical procedure, and rate of surgery was compared. Results. In all, 463 patients attended hand trauma services during the lockdown period compared to 793 in 2019 (32% reduction); 190 surgical procedures were carried out during lockdown compared to 236 in 2019 (20% reduction). Intervention rate was higher during the lockdown period (41% compared to 30%). There was no difference in the type of cases. In the first half of lockdown, 47% fewer procedures were performed than in 2019, but in the second half of lockdown 13% more procedures were carried out than the same period in 2019. Conclusion. Requirements for hand trauma surgery remain high during a pandemic lockdown. Attendances and surgical requirements can be expected to steadily return to normal levels during a prolonged lockdown period. Throughout any future lockdown period adequate surgical provision must be maintained for patients with hand injuries. Cite this article: Bone Joint Open 2020;1-10:639–643

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

The Poole Traction Splint (PTS) is a non-invasive technique that applies dynamic traction to the affected digit using materials readily available in the outpatient department. The primary aim of this study was to document the outcome of the PTS for hand phalangeal fractures. Over a four-year period (2017–2021), suitable patients were reviewed and referred for PTS to the hand physiotherapists. Functional outcome measures included range of motion (ROM), return to work, and a DASH score. In addition, a healthcare cost analysis was carried out. A total of 63 patients were treated with a PTS from 2017 to 2021. Data was analysed for 54 patients with 55 digits. The mean age was 43 years (17–72) and 53.7% (n=29) were female. There were 43 fractures involving the proximal phalanx and 12 involving the middle phalanx. The mean final composite range of movement averaged 209˚ (110–270°), classified as ‘good/excellent’ by ASSH criteria. The mean DASH score was 13.6 (0-43.2; n=45). All patients were able to return to work. Only two (3.7%) digits required conversion to surgical fixation. The PTS resulted in approximate savings of £2,452 per patient. The PTS is a cost-effective non-invasive low risk outpatient treatment method which provides a functional ROM and good functional outcomes in the treatment of complex phalangeal hand fractures, with minimal risk of surgical intervention being required

Alcohol hand rubs, endorsed by WHO and NICE guidelines, are integral to modern surgical practices. Our objective was to assess how different scrubbing methods impact overall water usage by the surgical team, shedding light on variations among team members and their environmental implications. Over three consecutive arthroplasty lists spanning a week, water usage during scrubbing was observed for the operating team. Blinding all team members, including the anesthetist, consultant surgeon, orthopaedic registrar, orthopaedic SHO, and scrub nurse, during water usage calculations was implemented. Automated taps, using motion sensors, posed a challenge due to variable water quantity, necessitating water flow calculations per sensor movement. The senior surgeon, with over 20 years of experience, follows a traditional approach, starting with a morning prescrub and using an alcohol tub for each case, except when hands are soiled. We observed a total of 14 cases of lower limb primary arthroplasty. The cumulative water usage for scrubbing by the entire team was 193 liters, yielding a mean of 13.8 liters (±1.85) per case. The anaesthetist demonstrated the most conservative water usage, utilizing a total of 11.85 liters with a mean of 0.84 liters per case. Notably, alcohol rub was employed for half of the observed time, contributing to this efficient use. The senior operating surgeon used a total of 15.6 liters, averaging 1.1 liters per case. In contrast, the SHO and the registrar exhibited the highest water consumption, totaling 121.6 liters and yielding a mean of 5.7 liters per case. The nurses’ collective water usage for scrubbing amounted to 44.8 liters. Adopting alcohol rub, as endorsed by WHO, results in a remarkable 10-fold reduction in water usage, aligning with global health guidelines. This highlights significant potential for resource conservation in surgical procedures, presenting a practical and environmentally conscious approach to surgical scrubbing practices

This study aims to determine the incidence of surgical site infection leading to reoperation for sepsis following minor hand procedures performed outside the main operating room using field sterility in the South African setting. The investigators retrospectively reviewed the records of 485 patients who had WALANT-assisted minor hand surgery outside a main operating theatre, a field sterility setting between March 2019 and April 2023. The primary outcome was the presence or absence of deep surgical site infection that required reoperation within four weeks. Cases included where elective WALANT minor hand procedures, a minimum age of 18 with complete clinical records. The patients were mostly female (54.8%), with a mean age of 56.35 years. The majority of cases were trigger finger and carpal tunnel release. An overall 485 cases were reviewed, the deep surgical site infection rate resulting in reoperation within 4 weeks post-operatively was 1.24% ((95% Confidence Interval (CI) 0.0034 to 0.0237); p = 0.009). Minor hand procedures performed under field sterility using WALANT have a low surgical site infection rate. The current study's infection rates are comparable to international surgical site infection rates for similar surgeries performed in main operating rooms using standard sterilisation procedures. Field sterility is a safe and acceptable clinical practice that may improve work efficiency in public sector

The aim of this investigation is to firstly quantify the burden of disease, and secondly qualify the organisms being cultured during debridement to establish their sensitivities to available antibiotics. This study will also look at the concomitant burden of Human Immunodeficiency Virus (HIV) and Diabetes Mellitus (DM) in cases of hand sepsis, to establish whether these two disease processes require special consideration and treatment tailoring. The method employed to collect the data will be retrospective collection of patient information, using random sampling. Included patients will be adult patients who undergo debridement and have a sample registered on the National Health Laboratory System (NHLS). The daily intake sheet will be used to collect patients details and these details will then be used to collect results of intra-operative specimens using the NHLS. These patient details will also be used to check patients’ HIV results and HBA1c (Glycated Haemoglobin A1c) results. Majority of the specimens revealed Methicillin Sensitive Staphylococcus Aureus (MSSA), with a reassuringly low rate of Methicillin Resistant Staphylococcus Aureus (MRSA) when compared to international data. The yield of patients tested for HIV or DM was lower than expected, despite this being the standard of care. The projected impact of this study will be assessment of the current burden of disease and then clarification of our current management strategy, in order to assess if it would be possible to change to a more cost-effective antibiotic with a narrower spectrum of bacteria coverage. The potential exists to not only implement cost saving measures, but also promote antibiotic stewardship by decreasing the practice of empiric broad-spectrum antibiotic use

In patients with hand sepsis does bedside debridement compared to operating theatre debridement have similar clinical outcomes, hospital cost and time to discharge in a District Hospital setting in South Africa?. A case series of 130 adult patients presenting to a district level orthopaedic unit over 1 year with hand sepsis requiring debridement. All included patients were debrided at the bedside (i.e. the emergency room, ward, OPD) under wrist or digital block. Patients excluded from the study included patients with necrotising soft tissue infections that required debridement in theatre. A cost analysis was done based on operating theatre (OT) costs saved as defined by Samuel1 et al. If an average theatre time of 45 min is taken then the cost saved per patient is approximately R1500 and approximately R300000 for the patients included in the case series. This excludes ward and other hospital costs related to a longer hospital admission. The mean time to discharge for the included patients was 24 hours. This study suggests that bedside debridement can be a viable and cost effective option for selected cases of hand sepsis that can avoid the high cost and time associated with operating theatre debridement with similar outcomes. This has implications for the future treatment of hand sepsis in resource constrained settings were operating theatre time is not only very expensive but also very scarce

Background. Patients with hand injuries frequently present to Emergency Departments. The ability of junior doctors to perform an accurate clinical assessment is crucial in initiating appropriate management. Objectives. To assess the adequacy of junior doctor hand examination skills and to establish whether further training and education is required. Methods. A double-centre study was conducted using an anonymous survey assessing hand examination completed by junior doctors (Foundation year 1 and Senior House Officer grades) working in Trauma & Orthopaedics or Emergency Departments. The survey covered all aspects of hand examination including assessment of: Flexor and Extensor tendons, Nerves (motor and sensory) and Vascular status. Surveys were marked against answers pre-agreed with a Consultant hand surgeon. Results. 32 doctors completed the survey. Tendons: 59% could accurately examine extensor digitorum, 41% extensor pollicis longus, 38% flexor digitorum profundus and 28% flexor digitorum superficialis. Nerves – Motor: 53% could accurately examine the radial nerve, 37% the ulnar nerve, 22% the median nerve and 9% the anterior interosseous nerve. Nerves – Sensory: 88% could accurately examine the radial nerve, 81% the ulnar nerve, 84% the median nerve and 18.8% digital nerves. Vascular: 93% could describe 3 methods of assessing vascularity. Conclusions. Tendon and neurological aspects of hand clinical examination were poorly executed at junior doctor level in this pragmatic survey. This highlights the need for targeted education and training to improve the accuracy of junior doctor hand injury assessment and subsequent improving patient treatment and safety. Recommendations include dedicated hand examination teaching early in Orthopaedic/A&E placements and introduction of an illustrated Hand Trauma Examination Proforma. Level of evidence. III - Evidence from case, correlation, and comparative studies

Aim. Left sided hip fractures are more common but no obvious cause has been identified. Left handedness has previously been associated with an increased risk of fracture for a number of sites but to the best of our knowledge no association between handedness and hip fracture has previously been reported. Methods. 2 separate 6-month prospective reviews of hip fracture patients aged over 65 years-of-age were conducted at 2 different hospitals. Handedness was dete2rmined at the time of admission. The second review focused on the use of walking aids. Patients with a previous cerebrovascular accident, neurological condition or contralateral hip prosthesis were excluded due to increased balance problems and falls risk. Results. Hand dominance was recorded for 339 patients; 304 right and 35 left. 91 patients were excluded. Of the remaining 248 patients more than twice as many (2.06 times) fractured their hip on the side of their non-dominant hand. For left handed individuals this increased to 4.6 times. Walking aid use was recorded for 102 patients. For patients using no walking aids, a Zimmer frame or 2 walking sticks; equal numbers of patients sustained right and left hip fractures. While 97.7% of patients using 1 walking stick did so in their dominant hand, sustaining 84% contralateral hip fractures. Conclusions. The direction in which people fall and the causes of hip fractures are clearly multi-factorial. However there is a clear association between hand dominance and the side of hip fracture, particularly in left handed individuals. Walking aids also play a role with 97.7% of patients using a walking stick in their dominant hand resulting in 84% contralateral hip fractures. By being aware of this association it may be possible to target both patient education and physiotherapy potentially reducing the number of patient falls and associated hip fractures

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. Declaration of Interest. (a) fully declare any financial or other potential conflict of interest

Smith's fractures generally occur when falling on a flexed wrist; however, orthopedic trauma surgeons often encounter distal radius fractures with volar displacement in patients who have allegedly fallen on the palm of their hands. This study aimed to reveal both the basic and clinical pathogenesis of Smith's fracture through a step-by-step investigation. We enrolled 17 patients with Smith's fractures, of which 71% fell on the palm and only 6% on the dorsum of the hand. First, we interviewed the outpatients to determine the mechanics of the injury and the position of their arm during injury. Second, we created a three-dimensional (3D) finite element model to predict the arm's position when the Smith's fracture occurred, which finite element analysis revealed as a 30° angle between the long axis of the forearm and the ground in the sagittal plane. Third, using this predicted position, we conducted experiments on 10 fresh frozen cadavers to prove the possibility of causing a Smith's fracture by falling on the palm of the hand. The results showed Smith-type fractures in seven of 10 wrists, whereas Colles-type fractures did not occur. Finally, we analyzed stress distribution in the distal radius when a Smith's fracture occurs using the 3D finite element model. In conclusion, this study demonstrates that Smith's fractures can also occur by falling on the palm of the hand

The April 2015 Wrist & Hand Roundup360 looks at: Non-operative hand fracture management; From the sublime to the ridiculous?; A novel approach to carpal tunnel decompression; Osteoporosis and functional scores in the distal radius; Ulnar variance and force distribution; Tourniquets in carpal tunnel under the spotlight; Scaphoid fractures reclassified; Osteoporosis and distal radial fracture fixation; PROMISing results in the upper limb

A prospective series of 32 cases with tuberculosis of the hand and wrist is presented. The mean age of the patients was 23.9 years (3 to 65), 12 had bony disease and 20 primarily soft-tissue involvement. The metacarpal of the little finger was the most commonly involved bone. Pain and swelling were the usual presenting features and discharging sinuses were seen in three cases. All patients were given anti-tubercular chemotherapy with four drugs. Operative treatment in the form of open or arthroscopic debridement, or incision and drainage of abscesses, was performed in those cases where no response was seen after eight weeks of ATT. Hand function was evaluated by the modified score of Green and O’Brien. The mean was 58.3 (25 to 80) before treatment and 90.5 (80 to 95) at the end. The mean follow-up was for 22.4 months (6 to 43). Conservative treatment was successful in 24 patients (75%). Eight who did not respond to chemotherapy within eight weeks required surgery. Although tuberculosis of hand has a varied presentation, the majority of lesions respond to conservative treatment

Introduction. Hand tumors are usually rare and there is not much literature about series of cases. We have studied a series of 110 cases. Hand tumors do consists of both benign and malignant cases. Methods. We studied series of 110 cases at Karnataka Institute of Medical Sciences, Hubli and Mysore Medical College & Research Institute, Mysore. We retrospectively reviewed the records of 110 patients who underwent double ray amputations at our center over few years: few had amputations of the fourth and fifth rays and others amputation of the second and third rays. Mean age at surgery was 34 years (range, 10–45 years), and minimum follow up was 64 months (mean, 98 months; range, 64–136 months). Some patients had high-grade soft tissue sarcomas of the hand, synovial sarcomas, malignant peripheral nerve sheath tumors, and undifferentiated sarcoma. No patients had detectable metastases at surgery. Results. All patients were completely disease-free at latest follow up. One patient was alive with lung metastases detected 32 months after surgery. No patients developed local tumor recurrence. Functional assessment showed a mean Musculoskeletal Tumor Society score of 24 (range, 19–28) and mean grip strength 24% of the contra lateral side (range, 17%–35%). Conclusions. The majority of osseous tumors of the hand are benign. The surgeon who evaluates and treats osseous tumors of the hand has to be familiar with limb anatomy, tumor biology, various presentations of the tumors and the range of treatment possibilities and their limitations. Lesions in the hand more often present earlier in their course than those at other sites, just because they are more likely to superficial and easily noticed. Ganglion cyst is the most frequently encountered comprising 50–70% of benign tumors of hand. Enchondroma was the next common benign bone tumour followed by osteoid osteoma, osteoblastoma, aneurismal bone cyst, giant cell tumor, epidermoid cyst, and osteochondroma. Although malignant neoplasms in the hand that arise from tissues other than the skin are very rare, the hand may be the site of distant breast, lung, kidney, esophagus, or colon adenocarcinoma metastases, most of which have a predilection for the distal phalanges. Malignant tumours of the hand are rare, although there remain many instances in which marginal excisions are performed for unsuspected malignant hand lesions. Suboptimal biopsy incisions and inadvertent contamination during these excisions may result in larger resections or amputations being necessary to ensure complete removal of the tumour with negative margins

The August 2014 Wrist & Hand Roundup360 looks at: Trapeziectomy superior to arthrodesis;Tamoxifen beneficial in the short term; Semi-occlusive dressing “the bee’s knees” even with exposed bone; “Open” a relative concept in the hand and wrist; Editorial decisions pushing up standards of reporting; Ulnar variance revisited; Traditionalists are traditional; Diabetes not so bad with carpal tunnel

The World Health Organization (WHO) launched the first Global Patient Safety Challenge in 2005 and introduced the ‘5 moments of hand hygiene’ in 2009 in an attempt to reduce the burden of health care associated infections. Many NHS trusts in England adopted this model of hand hygiene, which prompts health care workers to clean their hands at five distinct stages of caring for the patient. Our review analyses the scientific foundation for the five moments of hand hygiene and explores the evidence, as referenced by WHO, to support these recommendations. We found no strong scientific support for this regime of hand hygiene as a means of reducing health care associated infections. Consensus-based guidelines based on weak scientific foundations should be assessed carefully to prevent shifting the clinical focus from more important issues and to direct limited resources more effectively. We recommend caution in the universal adoption of the WHO ‘5 moments of hand hygiene’ by orthopaedic surgeons and other health care workers and emphasise the need for evidence-based principles when adopting hospital guidelines aimed at promoting excellence in clinical practice

The August 2013 Wrist & Hand Roundup. 360 . looks at: random group therapy is no good at treating OA of the hand; salvaging failed CMCJ arthroplasty; scaphocapitate arthrodesis for instability in manual workers; Brunelli tenodesis and scapholunate instability; night splints for Dupytren’s revisited; the smallest IM nail?; early diagnosis of CRPS?; and endoscopic carpal tunnel release?

The April 2012 Wrist & Hand Roundup. 360 . looks at releasing the trigger finger, function in the osteoarthritic hand, complex regional pain syndrome, arthroscopic ligamentoplasty for the injured scapholunate ligament, self-concept and upper limb deformities in children, wrist arthroscopy in children, internal or external fixation for the fractured distal radius, nerve grafting, splinting the PIPJ contracture, and finding the stalk of a dorsal wrist ganglion

Purpose of study:. To analyse the bacteriological spectrum, identify most appropriate antibiotics for hand infections, and to characterize patterns and sites of hand infections. This information was collected against the background of a high prevalence of HIV infected patients and increasing antibiotic resistance. Description of methods:. This was a prospective, cross-sectional, analytical study done on 66 patients presenting with hand infections at a public hospital from January to June 2009. A standardised treatment protocol was followed in managing these patients. Data was collected from each participant, and laboratory reports were followed up for the identity and antibiotic susceptibility of causative organisms. All patients were counselled for HIV status and consenting participants were tested. Summary of results:. Staphylococcus aureus was the commonest isolate. Results show that Cloxacillin is still an effective first line antibiotic for community acquired hand infections in the absence of immunosuppression. Alternative empiric therapy would be Clindamycin – especially in the B-lactamase intolerant patient. HIV infection played a significant role in the bacteriology of hand infections with an increased incidence of polymicrobial and gram negative infections. Data regarding age, gender, types of infection, mechanism of injury, x-ray findings and laboratory values are also reported. Conclusion:. Hand infections are common conditions that have significant morbidity. Referral is often delayed and infections present late. Immunosuppression seems to play a role in the bacteriology, the incidence of polymicrobial infections and the antibiotic sensitivity. Cloxacillin seems to be an adequate first line treatment for acute community acquired bacterial hand infections in immunocompetent patients in our institution, excluding human bites and farm yard injuries

The fingers and thumb are the second most common site for dislocation of joints following injury (3.9/10,000/year). Unlike fractures, the pattern and patient reported outcomes following dislocations of the hand have not previously been reported. All patients presenting with a dislocation or subluxation of the fingers or thumb were included in this cohort study (November 2008 and October 2009). Patient demographic and injury data were obtained and dislocation pattern confirmed on radiographs. Patient reported outcomes were obtained using the Michigan Hand Outcome Questionnaire (MHQ). There were 202 dislocations/subluxations recorded. MHQ scores were obtained at 3–5 years for 74percnt; patients. The average age at injury was 40 years, 76percnt; (146) patients were male and 11percnt; (23) injuries were open. 50percnt; (101) of the dislocations were dorsal, 28percnt; (57) were associated with fractures and 4percnt; (9) were recurrent. There were significant associations between: 1, Direction of dislocation and finger involved (p=0.03); 2, Joint and mechanism of dislocation (p=0.001); 3, Mechanism and direction of dislocation (p=0.008). Older patients had significantly worse outcomes (p<0.001). This is the first study to assess the epidemiology and patient reported outcomes following dislocation of the fingers and thumb allowing us to better understand these injuries

Introduction: Synovial sarcoma ranks as the fourth most common sarcoma, but it is uncommon in the hand. Most Synovial Sarcomas arise in para-articular soft tissue such as tendon, tendon sheath and bursa adjacent to the large joints capsules. Arround 60–70% of these tumors involve lower extremity and they frequently affect knee, thigh and foot. The reported incidence for Synovial Sarcoma in hand is only 8.5%. Material and methods: We carried out a retrospective study of 6 hand and forearm sarcomas, of a series of 35 synovial sarcomas surgically treated in our center from 1991 to 1997, with a 6 years follow up (3y.–11y.). 3 patients were male and 3 female, with a mean age of 54 years at the moment of initial diagnosis. Histologically all of them were synovial sarcomas: 4 monophasic and 2 biphasic. The inmunochemistry showed that the neoplasic cells were positive for vimentin, epithelial membrane antigen and cytokeratin. 2 of them were localized in the palmar aspect of the hand (2 ulnar cases and 2 eminence tenar cases), an 2 cases were dorsal. 2 cases were misdiagnosed as benign lesions and treated with tumor excision at another center. Results: Primary treatment consisted of radical local excision of synovial sarcoma of the hand. 5 patients received adjuvant chemotherapy with CYVADIC and radiotherapy. 2 cases of recurrence received a second surgical treatment with forearm amputation. The mean time to recurrence was 12 months. At the end of the follow-up 3 patients developed metastatic disease and 2 of them died. Discussion: Synovial Sarcoma in hand is a highly malignant tumor; due to its morphology they can be misdiagnosed as benign lesions such as aggressive fibromatosis or ganglion cysts. If we diagnose a soft tissue tumor in hand we must practice complementary tests to achieve early diagnosis. It is also important the multidisciplinary treatment of Synovial Sarcoma

Objectives: To establish the side incidence of acute lumbar disc prolapse and to determine whether there is a correlation between the side of the prolapse and hand dominance. Design: A retrospective study of consecutive cases of acute lumbar disc prolapse in which the diagnosis was confirmed at operation and the patients contacted about hand dominance. Summary of background data: The side incidence of operatively confirmed disc herniation does not appear to have been reported. Lifting and turning with the trunk in the flexed position is the commonest cause of an acute disc prolapse. Flexion and rotation of the lumbar spine, under load, may also give rise to unilateral fractures in the lumbar spine in fast bowlers in cricket and in eighty percent of these cases the fracture occurs on the opposite side to the bowling arm (ref . 1. ) Given that the majority of the population (eighty nine percent) are right handed it was speculated that the incidence of lumbar disc prolapse might not be equal and might be greater on the side opposite the dominant hand. Methods: From a review of case notes one hundred and twenty six patients were identified in which a sequestrated disc fragment was confirmed at operation. The side of the prolapse was noted. These patients were contacted to determine their hand dominance. Results: Fifty nine patients (47%) had a disc prolapse on the right side and sixty seven (55%) had a disc prolapse on the left side. There was no statistically significant difference in the numbers. Ninety two of the one hundred and twenty six patients contacted about their hand dominance responded: eighty three patients (90.2%) were right handed, eight (8.7%) were left handed and one patient (1.1%) was ambidextrous. Of the eighty three right handed patients, forty (48.2%) had a left sided disc prolapse and forty three (51.8%) had a right sided disc prolapse. Conclusion: This study revealed no difference in the side incidence of lumbar disc prolapse. There was no correlation either with the side of the prolapse and hand dominance. The findings are considered to support the view that a disc prolapse, and the side on which it occurs, is not a consequence of a single unilateral action but an end product of pre-existing disc degeneration in a midline structure

Initially, all surgeons in Australia were generalists and those with an interest in the anatomy of the hand performed hand surgery. Early hand surgeons, such as Benjamin Rank, excelled and Rank and Wakefield's Textbook of Hand Surgery was widely used throughout the world. Eventually, groups of like-minded surgeons formed the Australian Hand Club in 1972, which subsequently became formalised as The Australian Hand Surgery Society (AHSS), in 2001. A very high standard of hand surgery has been achieved in Australia, with most hand surgeons having trained in either plastic surgery or orthopaedic surgery, and then further trained in Fellowships in Europe or North America. Bernard O'Brien and John Hueston achieved international recognition in the field of microsurgery and Dupuytren's surgery. Wayne Morrison has been responsible for pioneering work in toe–to–hand transfer and basic research. Tim Herbert changed the way fractures of the scaphoid are managed throughout the world. In 2007 the AHSS commenced a Travelling Fellowship Programme to facilitate an increased involvement in Australia in academic hand surgery and to foster contacts between hand surgeons of the future. At the present time, the AHSS is concentrating on education and training in order to raise the overall standard of management of hand surgery, particularly in relation to after hours' trauma. This is particularly necessary in rural and regional areas where hand surgery has traditionally been treated by occasional practitioners. There is a risk that hand surgery falls between the two stools of plastic surgery and orthopaedic surgery and the AHSS wishes to further formalise training and education within the Royal Australasian College of Surgeons (RACS) as a single training stream in the future. There are potential threats both within and without, with safe working hours a particular threat in relation to reducing both the quantity and quality of training. The future will almost certainly involve greater emphasis on biomaterials and prosthetic compounds, but trying to ensure a uniformly high standard of hand surgery management throughout the country will remain as a primary focus

Purpose: Hand localisations predominate in Ollier disease. There have however been few studies devoted to this topic and the one report available only presented a few cases. Treatment of multiple enchondromatosis is sometimes discussed with the treatment of solitary enchondromas despite different recurrence behaviour and aggressiveness. A specific approach is indicated. Material and methods: We present a retrospective series of 22 children treated for multiple enchondromatosis of the hand. One hand was involved in 11 and both hands in 11. We thus identified 246 enchondromas on 33 hands. One girl with Maffucci syndrome died at the age of six years due to angiosarcomatous degeneration of the leg. Results: At diagnosis, mean age was six years nine months. Pain and pathological fractures were exceptional, observed in three patients. Overall hand function remained satisfactory. We performed surgery for 14 patients (mean age 8 yr 8 mo) due to increasing symptoms and tumour volume. Five patients required two operations and one a third. We thus performed 18 interventions on 37 hand bones (51 surgical procedures). Simple curettage was performed in 21 cases, combined with autologous cancellous grafting in 30 others. One finger had to be amputated due to aggressive recurrence. Radio-lucent residual lesions were found in 62% of the children at mean 19 months follow-up. Discussion: Hand function remained satisfactory despite a worrisome radiographic aspect. The decision for surgery was basically made to improve the aesthetic aspect of the hand. Many surgical techniques have been proposed. In our experience, it is difficult to eradicate a treated lesion but grafting appears to be more effective than simple curettage. Conclusion: Function remains good during growth, fractures are exceptional. Lesions stabilise at the end of growth. We have not observed any case of chondrosarcomatous degeneration in our series of paediatric patients. There is however a risk of malignant degeneration which should be suspected in the event of pain, increased tumour volume or pathological fracture

Aims. Our purpose was to determine the quality of current randomised controlled trials (RCTs) in hand surgery using standardised metrics. Materials and Methods. Based on five-year mean impact factors, we selected the six journals that routinely publish studies of upper extremity surgery. Using a journal-specific search query, 62 RCTs met our inclusion criteria. Then three blinded reviewers used the Jadad and revised Coleman Methodology Score (RCMS) to assess the quality of the manuscripts. Results. Based on the Jadad scale, 28 studies were of high quality and 34 were of low quality. Methodological deficiencies in poorly scoring trials included the absence of rate of enrolment, no power analysis, no description of withdrawal or dropout, and a failure to use validated outcomes assessments with an independent investigator. Conclusion. A large number of RCTs in hand, wrist, and elbow surgery were of suboptimal quality when judged against the RCMS and Jadad scales. Even with a high level of evidence, study design and execution of RCTs should be critically assessed. Methodological deficiencies may introduce bias and lead to statistically underpowered studies.

Introduction. Failures in total knee arthroplasty (TKA) have been associated with overall lower limb malalignment and component malposition. Although traditional computer navigation systems improve component placement, they require fixation of the femoral and tibial reference arrays for software recognition using anchoring pins. This increases the risk of bony fracture, pin sites infection and osteomyelitis. Aim. This study aims to evaluate the accuracy of a new hand held navigation system (BrainLAB® Dash® Navigation system) that will avoid these complications. Materials and Methods. Power analysis was done prior to the conduct of this study. Two hundred patients diagnosed with tricompartmental osteoarthritis and underwent total knee arthroplasty by a senior surgeon were included in this study. 100 patients underwent TKA using the hand held navigation system while the other 100 patients underwent TKA using conventional technique. The primary outcomes of this study were the overall alignment of the lower limb and the position of the components. This was determined radiologically using the: 1) Hip-Knee-Ankle angle (HKA) for lower limb alignment; 2) Coronal Femoral-Component angle (CFA) and 3) Coronal Tibia-Component angle (CTA) for component position. Normal alignment was taken as 180 ± 3 degrees for the HKA and 90 ± 3 degrees for both the CFA and CTA. Results. There was no difference in the mean HKA, CFA and CTA between the hand held navigation group and the conventional group. For the CFA, the proportion of outliers was 7% and 17% in the hand held navigation and conventional group respectively (p=0.030). For the HKA and CTA, there was no difference in the proportion of outliers between the two groups. The duration of surgery was 73 ± 9 minutes and 87 ± 15 minutes in the hand held navigation and conventional group respectively (p0.001). Conclusion. Dash® is an effective intraoperative tool to reduce the duration of surgery while concurrently reducing the proportion of outliers. The authors recommend its routine use in TKA

Introduction: Suppurative conditions in closed cavities/tunnels require surgical drainage and irrigation for elimination of infection. The purpose of this study is to evaluate the pattern of extension of infections in hand compartments and the necessity for intraoperative and continuous postoperative catheter irrigation. Material and Methods: Compartmental infections of the hand and wrist (CIHW) were diagnosed in 42 consecutive patients involving the flexor tendon sheaths (pyogenic flexor tenosynovitis) (28); the tip (3); the carpal tunnel (2); or extended to multiple compartments including the above mentioned and the thenar, midpalmar, web and Parona’s (9). Three patients had diabetes mellitus, 2 suffered from bites, 15 had penetrating injuries and 7 were working with animals or meat products. Fifteen were previously treated in other centers. After meticulous clinical evaluation to define all the involved compartments, all patients were treated with drainage of the respective compartments, sheath irrigation and appropriate antibiotics, whereas continuous postoperative catheter irrigation was used in 24. Hand therapy started the third postoperative day. Results: Mean follow-up time was 20 months. The most common pathogen was S. aureus (14 patients) whereas cultures were negative in 15. Three patients received additional fungal treatment. Results were excellent or very good in 25 hands and good in 12 regaining full or near full ROM. Recurrence of infection in 4 (that were initially treated inadequately in other centers or had intraoperative sheath irrigation without postoperative continuous irrigation) necessitated a revision of the procedure with extensive debridement and continuous postoperative irrigation. Finally, 1 patient developed complex regional pain syndrome. Conclusions: A high index of suspicion and profound knowledge of the anatomy is essential for early diagnosis and prompt surgical treatment of CIHW. Initially «benign» infections often extend in multiple compartments of the hand as a result of inadequate initial treatment. Intraoperative irrigation is not always adequate for the resolution of infection, especially in neglected cases or cases with underlying conditions. Early surgical debridement of all the involved compartments in combination to continuous postoperative irrigation, administration of appropriate antibiotics and precocious onset of hand therapy is the treatment of choice for these potentially debilitating, infectious conditions of the hand

The accurate assessment of skeletal maturity is essential in the management of orthopaedic conditions in the growing child. In order to identify the time of peak height velocity (PHV) in adolescents, two systems for assessing skeletal maturity have been described recently; the calcaneal apophyseal ossification method and the Sanders hand scores. . The purpose of this study was to compare these methods in assessing skeletal maturity relative to PHV. We studied the radiographs of a historical group of 94 healthy children (49 females and 45 males), who had been followed longitudinally between the ages of three and 18 years with serial radiographs and physical examination. Radiographs of the foot and hand were undertaken in these children at least annually between the ages of ten and 15 years. We reviewed 738 radiographs of the foot and 694 radiographs of the hand. PHV was calculated from measurements of height taken at the time of the radiographs. . Prior to PHV we observed four of six stages of calcaneal apophyseal ossification and two of eight Sanders stages. Calcaneal stage 3 and Sanders stage 2 was seen to occur about 0.9 years before PHV, while calcaneal stage 4 and Sanders stage 3 occurred approximately 0.5 years after PHV. . The stages of the calcaneal and Sanders systems can be used in combination, offering better assessment of skeletal maturity with respect to PHV than either system alone. .

The August 2015 Wrist & Hand Roundup360 looks at: Scaphoid screws out?; Stiff fingers under the spotlight; Trigger finger: is complexity needed?; Do we really need to replace the base of the thumb?; Scapholunate ligament injuries and their treatment: a missed research opportunity?; Proximal row carpectomy versus four-corner arthrodesis

Aims. The aim of this study was to compare the Push Ortho Thumb Brace CMC and a custom-made orthosis in the treatment of patients with primary osteoarthritis of the carpometacarpal joint of the thumb. Our outcome measures were pain scores, tests of hand function, patient satisfaction and patient preference. Patients and Methods. A multicentre crossover randomised controlled trial was conducted which included 63 patients (44 women) with primary osteoarthritis of the carpometacarpal joint of the thumb. Of these, 59 patients with a mean age of 60.1 years (standard deviation 8.2), completed the study. Patients used both orthoses for two weeks with a two-week washout period in-between. Pain was measured on a 10-cm visual analogue scale. Hand function was assessed using the Jebsen Taylor Hand Function test, Nine Hole Peg Test, key grip, pinch grip and Functional Index for Hand Osteoarthritis. Patient preference was assessed using the Dutch version of the Quebec User Evaluation of Satisfaction with Assistive Technology score. Results. Both orthoses resulted in a minor reduction in pain scores without significant difference between the two orthoses. The Push Ortho Thumb Brace CMC interfered less with key grip (p < 0.001) and the Nine Hole Peg Test (p < 0.001) than the custom-made orthosis. The Push Ortho Thumb Brace CMC had a higher patient satisfaction (p < 0.001) and most patients preferred this orthosis for future use. Conclusion. When considering an orthosis for osteoarthritis of the carpometacarpal joint of the thumb, patients may prefer the Push Ortho Thumb Brace CMC. Cite this article: Bone Joint J 2017;99-B:237–44

We have investigated the oncological outcome of 63 patients with soft-tissue sarcomas of the hand managed at three major centres in the United Kingdom. There were 44 males and 19 females with a mean age of 45 years (11 to 92). The three most common diagnoses were synovial sarcoma, clear cell sarcoma and epithelioid sarcoma. Local excision was carried out in 45 patients (71%) and amputation in 18 (29%). All those treated by amputation had a wide margin of excision but this was only achieved in 58% of those treated by local excision. The risk of local recurrence was 6% in those treated by amputation compared with 42% for those who underwent attempted limb salvage. An inadequate margin of excision resulted in a 12 times greater risk of local recurrence when compared with those in whom a wide margin of excision had been achieved. We were unable to demonstrate any role for radiotherapy in decreasing the risk of local recurrence when there was an inadequate margin of excision. Patients with an inadequate margin of excision had a much higher risk of both local recurrence and metastasis than those with wide margins. The overall survival rate at five years was 87% and was related to the grade and size of the tumour and to the surgical margin. We have shown that a clear margin of excision is essential to achieve local control of a soft-tissue sarcoma in the hand and that failure to achieve this results in a high risk of both local recurrence and metastastic disease

It has been shown that extremity injuries form a large proportion of the operative surgical workload in conflict situations. Injuries to the hands are an important subgroup and hand surgery has a long association with military surgery. While most hand injuries do not require surgical intervention, those that do, require that military surgeons should be well versed in the principles of hand surgery. The concepts of staging and/or damage control surgery are well applied to this region. The nature of military medical support necessarily changes in the transition from war fighting to a post-conflict phase. We examine the activity in the sole British Military Hospital serving a multi-national divisional area in Iraq over 2004. During this post conflict phase, the spectrum of hand trauma is characterised. The overwhelming majority of hand trauma resulted in soft tissue injury. There was a clear predisposition to hand trauma for males, manual workers, combat soldiers and engineers/mechanics. X-ray imaging is heavily used in this environment. Even where soldiers are returned to duty they are often restricted in the duties that they can perform. The results of this study reinforce the relevance of basic principles of hand trauma management, particularly in challenging environments. These knowledge and skill requirements should be emphasised for the war surgeon and the emergency physician. Hand surgery is an evolving speciality that continues to find clear and direct applications for the military surgeon

The June 2015 Wrist & Hand Roundup360 looks at: Collagenase and Dupuytren’s disease – a genuine alternative to surgery?; iPad PROMise?; Should we learn how to do endoscopic carpal tunnel release?; Two-week radiographs a relic of the past?; Bible? Aspirate or excise?; Patient expectations and trapeziometacarpal osteoarthritis; Splintage in the treatment of sagittal band incompetence and extensor tendon subluxation

Introduction: Patients can vary widely in their illness perceptions and subsequently, the manner in which they respond and adapt to health threats. A patient’s perception about his/her hand injury may explain their health behaviours such as adherence to post-operative therapy, coping, emotional response and eventual clinical outcome. Aims: To examine illness beliefs in patients with hand injuries in the acute trauma setting. Methods: The disability and severity of injury were determined using the DASH questionnaire and HISS score. The revised Illness Perception Questionnaire(IPQR) was used to explore the patient’s illness perception. Results: Fifty seven patients were recruited. There was no correlation between the DASH and HISS scores, or their correlation with the different components of the IPQ-R scores. The cohort was optimistic about their treatment and duration of recovery. There was some evidence to suggest that patients with more severe injury were over-optimistic about recovery. Beliefs of negative consequences, chronic, cyclical duration and low illness coherence were linked with negative emotional response. Female patients and dominant hand injuries reported higher subjective disability. Conclusions: The lack of correlations suggests that illness perceptions were not influenced by the severity of the injury. Patients in this cohort were optimistic about recovery, particularly in those with more severe injury (over-optimistic). These findings suggest that there could be a role for psychological intervention in hand injury. Longitudinal research is needed to evaluate illness beliefs in hand injury during the post-operative period

The October 2014 Wrist & Hand Roundup360 looks at: pulsed electromagnetic field of no use in acute scaphoid fractures; proximal interphalangeal joint replacement: one at a time or both at once; trapeziometacarpal arthrodesis in the young patient; Tamoxifen and Dupytren’s disease; and endoscopic or open for de Quervain’s syndrome?

Hand function in 33 patients with myelomeningocele, aged from 4 to 17 years, was investigated by clinical examination and formal tests of co-ordination and dexterity. The average score for hand function was 59% of normal and only two children had clinically normal upper limbs. Twenty-eight patients (85%) had cerebellar ataxia, either alone or combined with other abnormal signs, most commonly upper motor neuron lesions. Hand function was significantly better in children of 11 years and older, in children under 11 with milder degrees of hydrocephalus, and in the younger children who were right-handed. Function was not shown to be better in those with lesions lower in the spine, nor in those with stable spines as has been previously reported. When co-ordination of the upper limb, manual dexterity and simultaneous movements of both arms were examined separately, these three were affected equally. Some abnormalities of hand function could be overcome by encouraging affected children to sit up and to practise skillful use of their hands as early in life as possible

Acute swelling of the hand is a common problem after trauma or surgery and is associated with both pain and loss of function. We describe a prospective study of 47 patients in which we assessed the effects of a pneumatic compression device (A-V impulse hand pump) on the swollen hand. The pump reduced swelling by increasing the velocity of venous return as demonstrated by Duplex scanning of the median cubital vein. Continuous use of the pump for 48 hours gave a reduction of 78.6% in swelling of the injured hand compared with the opposite, uninjured side. Even when used intermittently, with the pump on for 12 hours out of 24, a statistically significant effect was seen. There was a subjective reduction in pain and an objective improvement in function of the hand. Use of the pump resulted in a nearly normal hand by the time of discharge from hospital after, on average, 48 hours

1. A report is made of 1000 consecutive cases of infection of the hand treated in the hand clinic of the Surgical Department of the Royal Victoria Infirmary, Newcastle-upon-Tyne. 2. Standard lesions are given a standard treatment. The methods of treatment are described and the results are expressed according to the time to healing from first attendance at the clinic. An attempt was made to review those cases in which a disability of any sort was anticipated, and an assessment made with regard to appearance and function. 3. Many patients came to hospital at a late stage when skin necrosis had already occurred, and particular attention is paid to the management of this complication. 4. It is concluded that the principles of conservative surgery applied to the treatment of infected hands give good results

The purpose of this prospective clinical study was to identify the true incidence, pattern, and location of the injury and nature of fracture following hand injuries in different paediatric age groups attending a hand unit. Three hundred and sixty children (237 boys and 123 girls) under 16 years of age who presented with hand injuries between 1st April 2000 and 30th September 2000 were included in the study. Bony injuries accounted for 65.5% (236 injuries), 33.3% (120 injuries) were soft tissue injuries. The projected annual incidence rate for skeletal injuries was 418/100,000 children/year. Incidence was low in toddlers (34/100,000), more than doubled in pre-school children (73/100,000) and steeply increased to around 20 fold after the 10th year (663/100,000). Girls had a higher incidence of hand injuries among toddlers and pre-school children. Crushing was the most common cause of hand injury (64%) and most injuries were sustained at home (45%). Toddlers sustained soft tissue injuries predominantly (86%) and older children sustained more bony injuries (77%). Sport was the cause of injures commonly in the older children. There was a higher incidence of fracture in little finger (52%) followed by the thumb (23%). The proximal phalanx was the most frequently fractured bone (67%) among the phalanges. Diaphyseal fractures (46%) were more common in the metacarpal and basal fractures (51%) were common in the phalanges. At discharge more than 80% of the patients felt that they were cured or significantly better. This paper highlights the changing pattern and the different varieties of hand injuries in different paediatric age groups

Pediatric hand surgery in general requires special considerations and this is even more true when planning surgery in children with CP. It is important for the surgeon to realize that the functional problems these children exhibit have their cause in a brain damage which is not amenable to hand surgical treatment. Therefore it is crucial to carefully analyze each child’s impairment including the voluntary motor control and the child’s specific needs before endeavoring into surgery. Associated impairments, such as mental retardation, nutritional problems, epilepsy, dystonia or severe sensory deficits may influence decision-making, but the crucial factor is often the child’s own wish for an improved function. A child that completely neglects his or her extremity is usually not helped by surgery, at least not in an attempt to get a better hand function. Hand surgery in CP mainly comes down to three techniques: 1. Reducing strength in spastic muscles by release operation, either at the origin of the muscle, at the insertion or as a fractional lengthening at the musculo-tendinous junction, 2. Increasing strength in weak antagonists by tendon transfer or 3. Stabilizing joints through an arthrodesis or a tenodesis. Most often a combination of these techniques is used. Almost all hand surgeons in this field have acquired their personal choice of procedures and scientific support for the benefits of the different techniques is scarce. My personal arsenal will be described in the panel but includes biceps-brachialis muscle release at the elbow, pronator teres rerouting, flexor carpi ulnaris to extensor carpi radialis brevis (Green’s) transfer and adductor pollicis muscle release in the palm combined with extensor pollicis longus rerouting for the thumb-in-palm deformity. In my mind, it is not most important which tendon transfer that is selected, but the choice of which child to operate and at what age. It is also important to tension the tendon transfers exactly right and to plan the postoperative treatment properly. The surgeon should, of course, also make sure that the child’s and the parent’s expectations on the results are realistic. Botulinum toxin A has now been used for several years in the treatment of children with cerebral palsy and the drug has been shown to be safe and effective in reducing muscle tone both in the lower and the upper extremities. It has been more difficult to show effects on hand function especially in the long-term perspective. I will present our treatment protocol for botulinum toxin injections. In 1994, a population-based health care program for children with CP was started in Lund in southern Sweden. All children in our region with a diagnosis of CP, born after Jan 1st 1990 are invited to follow the program which includes regular measurements of range of motion in extremity joints, standardized radiographic examinations of the hip joints and registration of surgery and spasticity treatments. The program, called CPUP has been very successful in the prevention of spastic hip dislocation, wind swept position and contractures. Some early results from the upper extremity part of CPUP will be presented. We believe that the program in time will give us valuable information on the natural course of joint motion and impairment of hand function in children with CP

The April 2014 Wrist & Hand Roundup. 360 . looks at: diagnosis of compressive neuropathy; relevant reviews; the biomechanics of dorsal PIP fracture dislocation; the more strands the better; and state of mind the best predictor of outcome

Aims: A previous study demonstrated that negative pressure wound therapy (NPWT) increases tissue pressure. This conflicts with the understanding that these dressings increase perfusion. This randomised case control study investigates the effects that circumferential NPWT has on perfusion in humans and how different suction pressures influence this. Methods: Ten healthy volunteers were recruited into the study and sequentially randomised to receive suction pressures of either −400 mmHg or −125 mmHg. With both hands placed in circumferential NPWT dressings, suction was only applied to one hand. Perfusion of both hands was then analysed simultaneously using radioisotope perfusion imaging. After allowing one week for complete excretion and decay of the isotope, an identical experiment was done on the same volunteers’, this time using the contralateral hand as the test hand. A total of 20 scans were carried out. Data were analysed using the Wilcoxon and Mann-Whitney tests. Results: In the hands that received suction pressures of −400 mmHg, there was a highly significant mean reduction in perfusion of 40% (SD 11.5%, p< 0.0005). In the hands that received suction pressures of −125 mmHg there was also a highly significant mean reduction in perfusion (mean 17%, SD 8.9%, p< 0.0005). The reduction in perfusion of the group undergoing NPWT at −400 mmHg was significantly greater than the group undergoing NPWT at −125 mmHg (p< 0.015). Conclusion: Tissue perfusion beneath circumferential NPWT dressings is significantly reduced when suction is applied, regardless of whether suction pressures of −125 mmHg or −400 mmHg are utilised. There is a significantly greater reduction in perfusion at suction pressures of −400 mmHg, compared to −125 mmHg. This implies that circumferential NPWT should be used with extreme caution, if at all, on tissues with compromised perfusion. This finding represents a paradigm shift in our understanding of the mechanism of action of NPWT

Purpose of the study: Available epidemiological data on hand and wrist tumours are scarce and sometimes discordant. In our unit, these tumours are managed conjointly by hand surgeons and tumour specialists. We conducted an epidemiological study of 624 tumours treated from 1980 to 2008. Material and methods: The recruitment used three methods: diagnostic coding in the database, analysis of discharge letters, study of tumour registries. All hand and wrist tumours treated surgically in our unit were included retrospectively. Exclusion criteria were: patients aged less than 15 years and/or managed in the paediatric surgery unit; poorly identified cases; recurrences. Results: The study population included 624 tumours (375 female and 249 male). Mean age was 48 years (range 16–94). Eight tumours were malignant: 4 skin, 3 soft tissue, 1 bone metastasis of a primary renal tumour. Soft tissue tumour concerned 525 patients (84.1% of the study population). Respectively, 71 tumours concerned bone and 28 skin. There were 221 synovial cysts. The bone tumours exhibited a harmonious distribution for age and gender with a peak from 35 to 50 years and a sex ratio of 1/1. There were 43 chondromas found at all ages, mainly in long bones. Discussion: Our series is the third largest reported. A review of the literature identified the eight largest studies available. For 6452 tumours, 81.7% concerned soft tissues, 13% skin, 4.7% bone tissue. These lesions occurred at all ages with female predominance (60%). Malignant tumours were found in 4.4% of the cases. Exclusion of the paediatric cases and the retrospective nature of the data collection were the main biases of this work. Conclusion: Data on 624 hand and wrist tumours were in agreement with published work. Tumours involved mainly soft tissues. Synovial cysts predominated. Chondromas accounted for 70% of the bone tumours. Malignant tumours were rare (2.9%). For suspect cases, we recommend referral to a specialised centre for the management of malignant tumours of the hand. A pluridisciplinary analysis is indicated to adapt the diagnostic and therapeutic strategy

Background. In poliomyelitis; hand to knee gait is the sum of quadriceps weakness and fixed knee flexion deformity. Limb shortening is another added problem. Usually, each problem is attacked separately; with variable end results and complication rates for each procedure. Patients and methods. 22 patients (16–46 y.); with poliomyelitis with hand to knee gait due to fixed knee flexion deformity of mild to moderate degree (10–400); and limb shortening of 4.5–9.5 cm., were managed simultaneously by a single operation. A distal femoral metaphyseal anterior closing wedge (recurvatum) corrective osteotomy was done to treat acutely the fixed knee flexion deformity(and subsequently hand to knee gait). A modified Wagner or Orthofix frame was applied as a mono-plane mono-axial lengthening device to stabilize the osteotomy and to lengthen the short limb. Lengthening was started in all cases two weeks post-operatively. Results. All cases showed full correction of the deformity with elimination of the hand to knee gait problem and all showed the desired limb length equalization. The femora were lengthened to an average of 6.4 cm.(= 21 % of original femoral bone length), range of lengthening was: 4–9 cm. (= 11–26 %). The average healing index was 37 days per centimeter (with a range of 31 to 53 days per centimeter.). Conclusion. Simultaneous management of hand to knee and limb shortening could be achieved by a single osteotomy which is used to extend the knee acutely and for distraction two weeks later using a mono-lateral frame. Results were good, complications were few and accepted and the procedure is well tolerated by the patients

A series of 26 children was referred to our specialist unit with a ‘pink pulseless hand’ following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedures were recorded. The mean age at presentation was 8.6 years (2 to 12). There were eight girls and 18 boys. Only four of the 26 patients had undergone immediate surgical exploration before referral and three of these four had a satisfactory outcome. In one child the brachial artery had been explored unsuccessfully at 48 hours. As a result 23 of the 26 children presented with established ischaemic contracture of the forearm and hand. Two responded to conservative stretching. In the remaining 21 the antecubital fossa was explored. The aim of surgery was to try to improve the function of the hand and forearm, to assess nerve, vessel and muscle damage, to relieve entrapment and to minimise future disturbance of growth. Based on our results we recommend urgent exploration of the vessels and nerves in a child with a ‘pink pulseless hand’, not relieved by reduction of a supracondylar fracture of the distal humerus and presenting with persistent and increasing pain suggestive of a deepening nerve lesion and critical ischaemia

The June 2014 Wrist & Hand Roundup360 looks at: aart throwing not quite as we thought; two-gear, four-bar linkage in the wrist?; assessing outcomes in distal radial fractures; gold standard Swanson’s?; multistrand repairs of unclear benefit in flexor tendon release; for goodness’ sake, leave the thumb alone in scaphoid fractures; horizons in carpal tunnel surgery; treading the Essex-Lopresti tightrope; wrist replacement in trauma? and radial shortening reliable in the long term for Kienbock’s disease

The June 2013 Wrist & Hand Roundup. 360 . looks at: whether size is a limitation; cancellous bone grafting in scaphoid nonunion; the Kienböck’s dichotomy; late displacement of the distal radius; flexor slide for finger contracture; aesthetic syndactyly; flexor tendon repair; and fixation of trapeziometacarpal cups

Hand fasciotomy is a rarely performed procedure which should be considered by military surgeons, and performed where necessary. Maximising hand function is vital in all military patients, but is even more significant in those who have lost multiple limbs and require maximal function from remaining hands, which are commonly injured too. It is vital that compartments are decompressed expediently to minimize muscle ischaemia. Cases were identified from the JTTR from March 2003. Data were collected prospectively from Aug 2009 to Feb 2010. Patient notes were analysed and the following recorded –demographics, mechanism of injury (MOI), associated injuries, echelon of care at which fasciotomy was performed, indication recorded by operating surgeon, and specialty of operating surgeon. 9 patients were identified, median age was 23, MOI was IED in 8/9 and mine in 1/9/. All were multiply injured. 4/9 (44%) were performed at R3 and 5/9 (56%) at R4. All fasciotomies at R4 were performed at the first debridement, intrinsic muscles were found to be necrotic in 1 case. At R3 3/4 were performed by orthopaedic surgeons and 1/4 by a plastic surgeon, at R4 all were performed by hand surgeons, either orthopaedic or plastic. All fasciotomies performed at R4 were at the first debridement, and 1 revealed necrotic intrinsic muscles. This implies that some of these patients may have benefited from earlier procedures. In upper limb injury where it is not possible to passively flex the metacarpophalangeal joints to 90 degrees, decompressing the hand should be considered

Complex hand injuries are those which involve more than one functionally significant anatomic structure of the hand (i.e vessels, nerves, tendons, bones). The epidemiologic and management characteristics of these injuries, encountered in a specialized center covering an urban and agricultural population, were recorded and studied. Between 1997 and 2002 the Orthopaedic Department of the University of Ioannina surgically treated 211 complex hand injuries in 190 patients with a mean age of 35 year (range 2.5–73). The majority of patients were male (89%). The incidence of these injuries was low at the extremes of the age distribution (children and adults over 60 years old). The greatest incidence was in the 15–30 year old age group. The mechanism of the injury was found to be clean cut trauma in 31% and avulsion or crushing in 69%; with the later being frequent agricultural injuries. Fifty-nine per cent of the injuries were viable, while 41% where non-viable (complete amputation in 63% and incomplete in 37%). Of the non viable injuries 66% eventually underwent stump configuration. Primary repair of only one anatomical structure was performed in 58%, most commonly osteosynthesis and tendon suturing. In 42% primary repair of more than one structure was performed, most commonly osteosynthesis and tendonorrhaphy in avulsion injuries and neuroraphy combined with tendonorrhaphy in clean cut injuries. Complex hand injuries are frequently seen in young male adults and the most common mechanism of injury is avulsion-crushing. Most of them are work-related accidents, so prevention should focus on adherence to safety guidelines. Management of such injuries requires special surgical techniques and expertise, necessary for staged reconstruction

While primary squamous-cell carcinoma of the hand is common, metastasis of a squamous-cell carcinoma to the hand is very rare. It has been reported to arise from carcinoma of the lung and oesophagus and, rarely, from other tumours. We describe a patient with metastatic squamous-cell carcinoma occurring in the first web space of the hand from primary lung cancer, which remained undetected for 30 months after treatment of the metastasis

Aim. Bumps and lumps of the hand are a common cause for consultation in general practice. However not all of these lesions are of true neoplastic nature and malignant tumours are a rarity in this location. Method. The records of all tumours of the hand and wrist treated surgically at our institution in the period 1994 to 2009 were reviewed. Because of their non-neoplastic nature typical lesions of the hand such as ganglion cysts or palmar fibromatosis and the like were not included in this study. Histological entity, location, radiographic and clinical findings were analysed; malignant tumours were followed up by X-ray and MRI. Results. Out of 142 cases which were further investigated, there were 86 bone tumours and 56 soft tissue lesions. The mean age was 41 years (range 8 to 85), there were 57 male and 85 female patients.122 cases (86%) were benign lesions, 71 cases located in the bone and 52 cases in the soft tissue respectively. There were twenty malignant lesions, sixteen of which were bone tumours; the most common being chondrosarcoma (11), followed by metastases (3) and osteosarcoma (2). The group of malignant soft tissue tumours (4) was comprised of synovial sarcoma (2), Ewing sarcoma (1) and extraosseus myxoid chondrosarcoma (1). Out of 52 benign soft tissue tumours, pigmented villonodular synovitis (32), haemangioma (6) and lipomatous tumours (6) have been the most frequent entities. Chondroma (48), osteoid-osteoma (4) and giant cell tumour (3) were the most common benign bone tumours. Conclusion. Knowledge of tumour prevalence under consideration of the patient's age and location of the tumour is an important prerequisite for identifying neoplastic lesions of the hand

1. In a series of seventy-one patients with wringer injuries of the hand three basic types of lesion were observed: a) denuding of part of or the entire hand, usually accompanied by avulsion of the distal phalanges; b) small lacerated wounds with wide detachment of surrounding skin and frequent fractures; c) multiple cut injuries of digits or the entire hand with skin avulsions. 2. Treatment was guided by the following principles: a) improvement of blood supply in regions of impaired nourishment; b) stable primary fixation of bones with Kirschner wires; c) primary wound closure through free skin grafting with maximal utilisation of available flaps. 3. Surgical technique as applied in various typical cases is outlined

Introduction:. During the Christmas period a number of patients are admitted to the Chris Hani Baragwanath Academic Hospital (CHBAH) Hand Unit with explosive injuries to their hands caused by firecrackers. South African legislation restricts the sale and use of fireworks to adults, with a limitation being placed on the size of explosive and type of commercial outlet. Despite this an inordinate amount of explosive hand injuries are admitted over the festive season. Aim:. To evaluate the epidemiological pattern of firecracker injuries to the hand during the Christmas festive period and assess contributing factors. Comparison to a previous study in 2008 will also be evaluated. Method:. Patients with firecracker injuries to the hand were interviewed. Demographic information, events surrounding the incident including alcohol use, and origin of the explosive were recorded. Injuries were classified into minor, moderate and severe based on the amount of soft tissue and bony damage. Treatment and complications was recorded. The data is also compared to previous data obtained in 2008. Results:. 26 patients were admitted. 2 patients were injured with explosives from a legal source. Alcohol use was implicated in 10 of the injuries. 17 amputations were performed at various levels, 9 fractures and 2 dislocations were stabilised with K-wires. Sepsis was more common in severe injuries. The majority of patients were injured from mis-use with several patients suffering injuries following removal of explosives from children or from other people throwing explosives at them or their family.
