Aims

Though most humeral shaft fractures heal nonoperatively, up to one-third may lead to nonunion with inferior outcomes. The Radiographic Union Score for HUmeral Fractures (RUSHU) was created to identify high-risk patients for nonunion. Our study evaluated the RUSHU’s prognostic performance at six and 12 weeks in discriminating nonunion within a significantly larger cohort than before.

Fractures and nonunions of the proximal humerus are increasingly treated by open reduction and internal fixation. The extended deltopectoral approach remains the most widely used for this purpose. However, it provides only limited exposure of the lateral and posterior aspects of the proximal humerus. We have previously described the alternative extended deltoid-splitting approach. In this paper we outline variations and extensions of this technique that we have developed in the management of further patients with these fractures

Aims. A pragmatic multicentre randomised controlled trial (PROFHER) was conducted in United Kingdom National Health Service (NHS) hospitals to evaluate the clinical effectiveness and cost effectiveness of surgery compared with non-surgical treatment for displaced fractures of the proximal humerus involving the surgical neck in adults. . Methods. A cost utility analysis from the NHS perspective was performed. Differences between surgical and non-surgical treatment groups in costs and quality adjusted life years (QALYs) at two years were used to derive an estimate of the cost effectiveness of surgery using regression methods. . Results. Patients randomised to receive surgical intervention accumulated mean greater costs and marginally lower QALYs than patients randomised to non-surgery. The surgical intervention cost a mean of £1758 more per patient (95% confidence intervals (CI) £1126 to £2389). Total QALYs for the surgical group were smaller than those for non-surgery -0.0101 (95% CI -0.13 to 0.11). The probability of surgery being cost effective was less than 10% given the current NICE willingness to pay at a threshold of £20 000 for an additional QALY. The results were robust to sensitivity analyses. Discussion. The results suggest that current surgical treatment is not cost effective for the majority of displaced fractures of the proximal humerus involving the surgical neck in the United Kingdom’s NHS. Take home message: The results of this trial do not support the trend of increased surgical treatment for patients with displaced fractures of the proximal humerus involving the surgical neck within the United Kingdom NHS.

Aims

Osteopetrosis (OP) is a rare hereditary disease that causes reduced bone resorption and increased bone density as a result of osteoclastic function defect. Our aim is to review the difficulties, mid-term follow-up results, and literature encountered during the treatment of OP.

Aims. We aimed to identify the pattern of nerve injury associated with paediatric supracondylar fractures of the humerus. Patients and Methods. Over a 17 year period, between 1996 and 2012, 166 children were referred to our specialist peripheral nerve injury unit. From examination of the medical records and radiographs were recorded the nature of the fracture, associated vascular and neurological injury, treatment provided and clinical course. Results. Of the 166 patients (111 male, 55 female; mean age at time of injury was seven years (standard deviation 2.2)), 26 (15.7%) had neurological dysfunction in two or more nerves. The injury pattern in the 196 affected nerves showed that the most commonly affected nerve was the ulnar nerve (43.4%), followed by the median (36.7%) and radial (19.9%) nerves. A non-degenerative injury was seen in 27.5%, whilst 67.9% were degenerative in nature. Surgical exploration of the nerves was undertaken in 94 (56.6%) children. The mean follow-up time was 12.8 months and 156 (94%) patients had an excellent or good clinical outcome according to the grading of Birch, Bonney and Parry. Conclusion. Following paediatric supracondylar fractures we recommend prompt referral to a specialist unit in the presence of complete nerve palsy, a positive Tinel’s sign, neuropathic pain or vascular compromise, for consideration of nerve exploration. . Take home message: When managed appropriately, nerve recovery and clinical outcomes for this paediatric population are extremely favourable. Cite this article: Bone Joint J 2016;98-B:851–6

Aims. The aims of this study were to estimate the cost of surgical treatment of fractures of the proximal humerus using a micro-costing methodology, contrast this cost with the national reimbursement tariff and establish the major determinants of cost. Methods. A detailed inpatient treatment pathway was constructed using semi-structured interviews with 32 members of hospital staff. Its content validity was established through a Delphi panel evaluation. Costs were calculated using time-driven activity-based costing (TDABC) and sensitivity analysis was performed to evaluate the determinants of cost. Results. The mean cost of the different surgical treatments was estimated to be £3282. Although this represented a profit of £1138 against the national tariff, hemiarthroplasty as a treatment choice resulted in a net loss of £952. Choice of implant and theatre staffing were the largest cost drivers. Operating theatre delays of more than one hour resulted in a loss of income. Discussion. Our findings indicate that the national tariff does not accurately represent the cost of treatment for this condition. Effective use of the operating theatre and implant discounting are likely to be more effective cost containment approaches than control of bed-day costs. Take home message: This cost analysis of fractures of the proximal humerus reinforces the limitations of the national tariff within the English National Health Service, and underlines the importance of effective use of the operating theatre, as well as appropriate implant procurement where controlling costs of treatment is concerned.

We studied the epidemiology of 401 fractures of the shaft of the humerus in 397 patients aged 16 years or older. The incidence was 14.5 per 100 000 per year with a gradually increasing age-specific incidence from the fifth decade, reaching almost 60 per 100 000 per year in the ninth decade. Most were closed fractures in elderly patients which had been sustained as the result of a simple fall. The age distribution in women was characterised by a peak in the eighth decade while that in men was more even. Simple fractures were by far the most common and most were located in the middle or proximal shaft. The incidence of palsy of the radial nerve was 8% and fractures in the middle and distal shaft were most likely to be responsible. Only 2% of the fractures were open and 8% were pathological. These figures are representative of a population with a low incidence of high-energy and penetrating trauma, which probably reflects the situation in most European countries

Aims

The aim of this study was to determine the current incidence and epidemiology of humeral diaphyseal fractures. The secondary aim was to explore variation in patient and injury characteristics by fracture location within the humeral diaphysis.

Recent reports have suggested that a delay in the management of type-III supracondylar fractures of the humerus does not affect the outcome. In this retrospective study we examined whether the timing of surgery affected peri-operative complications, or the need for open reduction. There were 171 children with a closed type-III supracondylar fracture of the humerus and no vascular compromise in our study. They were divided into two groups: those treated less than eight hours from presentation to the Accident and Emergency Department (126 children), and those treated more than eight hours from presentation (45 children). There were no differences in the rate of complications between the groups, but children waiting more than eight hours for reduction were more likely to undergo an open reduction (33.3% vs 11.2%, p < 0.05) and there was a weak correlation (p = 0.062) between delay in surgery and length of operating time. Consequently, we would still recommend treating these injuries at the earliest opportunity

Secure fixation of displaced proximal fractures of the humerus is a challenging problem. A total of 32 patients with acutely displaced three- or four-part proximal fractures of the humerus were treated by open reduction and internal fixation using the proximal humeral internal locking system (PHILOS) plate. There were 23 women and nine men with a mean age of 59.9 years (18 to 87). Data were collected prospectively and the outcomes were assessed using the Constant score. The mean follow-up was for 11 months (3 to 24). In 31 patients (97%) the fracture united clinically and radiologically at a mean of 10 weeks (8 to 24). The mean Constant score at final review was 66.5 (30 to 92). There was no significant difference in outcome when comparing patients aged more than 60 years (18 patients) with those aged less than 60 years (14 patients) (t-test, p = 0.8443). There was one case each of nonunion, malunion and a broken screw in the elderly population. This plate provides an alternative method of fixation for fractures of the proximal humerus. It provides a stable fixation in young patients with good-quality bone sufficient to permit early mobilisation. Failure of the screws to maintain fixation in the elderly remains a problem

We used an inverted shoulder arthroplasty in 43 consecutive patients with a mean age of 78 years (65 to 97) who had sustained a three- or four-part fracture of the upper humerus. All except two were reviewed with a mean follow-up of 22 months (6 to 58). The clinical outcome was satisfactory with a mean active anterior elevation of 97° (35° to 160°) and a mean active external rotation in abduction of 30° (0° to 80°). The mean Constant and the mean modified Constant scores were respectively 44 (16 to 69) and 66% (25% to 97%). Complications included three patients with reflex sympathetic dystrophy, five with neurological complications, most of which resolved, and one with an anterior dislocation. Radiography showed peri-prosthetic calcification in 36 patients (90%), displacement of the tuberosities in 19 (53%) and a scapular notch in ten (25%). Compared with conventional hemiarthroplasty, satisfactory mobility was obtained despite frequent migration of the tuberosities. However, long-term results are required before reverse shoulder arthroplasty can be recommended as a routine procedure in complex fractures of the upper humerus in the elderly

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

Title. 3D distribution of cortical bone thickness in the proximal humerus, implications for fracture management. Introduction. CT imaging is commonly used to gain a better understanding of proximal humerus fractures. the operating surgeon however has a limited capacity to evaluate the internal bone geometry from these clinical CT images. our aim was to use clinical CT in a novel way of accurately mapping cortical bone geometry in the proximal humerus. we planned to experimentally define the cortico-cancellous border in a cadaveric study and use CT imaging software to map out cortical thickness distribution in our specimens. Methodology. With ethical approval we used fifteen fresh frozen human proximal humeri. These were stripped of all soft tissue and transverse CT images taken with a GE VCT Lightspeed scanner. The humeral heads were then subsequently resected to allow access to the methaphyseal area. Using currettes, cancellous bone was removed down to hard cortical bone. Another set of CT images of the reamed specimen were then taken. Using Mimics imaging software[Materialise, Leuven] and a CAD interface, 3-matic [Materialise, Leuven], we built 3D model representations of our intact and reamed specimens. We first had to define an accurate CT density threshold for visualising cortical contours. We then analysed cortical thickness distribution based on that experimented threshold. Results. we were able to statistically determine the CT threshold, in Hounsfield Units, that represents the cortico-cancellous interface in the proximal humerus. Our 3D colour models provide an accurate depiction of the distribution of cortical thickness in the proximal humerus. Discussion/Conclusions. Our Hounsfield value for the cortico-cancellous interface in the proximal humerus agrees with a similar range of 400 to 800 HU reported in the literature for the proximal femur. Knowledge of regional variations in cortical bone thickness has direct implications for basic science studies on osteoporosis and its treatment, but is also important for the orthopaedic surgeon since our decision for treatment options is often guided by local bone quality

Aims. The aim of this study was to statistically analyse the incidence and distribution of humerus fractures in the adult age group between 3rd and 10th decades. Methods. The total number of patients was retrieved from the audit department of the hospital using the codes to identify patients between 1997 and 2009. The data included total number of patients aged 20 to 100 years who were either reviewed in the fracture clinics or admitted to the hospital with forearm fractures along with patient gender, age at the time of incident and time of the year the incident occurred. Annual incidence of fractures along with the distribution of fracture incidence per year and per individual month was calculated. The patients’ age were classified in to 3rd to 10th decades. Linear regression analysis was carried out to identify the relationship between fracture incidence and the age or time of the injury. Correlation coefficients(R) and r2 were calculated for all the regression analyses. SPSS (version 16) and Microsoft Excel 2007 were used for statistics. Results. A total of 1280 fractures were identified that included 524 males and 756 females (F/M=1.44). The average age of patients was 60.87 years. Comparing the different months of the year for fracture incidence, the average of incidence of fractures was found to be highest in july per year. There was a linear increase in the incidence of fractures from january to september (R=0.94, r2=0.89) followed by a drop in subsequent months. The total number of humerus fractures per year increased from49 in 1997 to 137 in 2009. In both males and females, there was strong relation to linearity in the increase in the incidence of fractures per year from 1997 to 2009 (Females: R=0.89, r2=0.79, Males: R=0.87, r2=0.76). On comparison of the linear equations for males and females, the rate of increase in the incidence of fractures in females was found to be approximately 1.5 times that of males. In females, There was a linear increase in the fracture incidence from the 3rd to the 9th decade (R=0.96, r2=0.92) followed by a sudden drop in the 10th decade. In men, there was a linear decrease in the fracture incidence from the 3rd to the 9th decade (r2=0.81, R=0.90). Conclusion. In the last 13 years, there has been an increase in the incidence of humerus fractures in both men and women; however, the rate of increase in the incidence in women is almost 1.5 times that of men. There was a strong correlation between age and incidence of fractures in both men and women: with increasing age, the incidence of fracture increased in women and decreased in men. The drop in fractures in women the 10th decade can be attributed to a reduced living population after 90 years. The obtained linear equations can be useful in predicting the number of fractures occurring in a certain age group in a community

A single antegrade Rush nail was used to treat 37 fractures of the distal humerus extending to the olecranon fossa and up to 6.5 cm proximal to it. In order to stabilise the fracture, the bent tip of the Rush nail was directed into the lateral epicondylar ridge. This gave immediate stability. All the fractures united without residual stiffness of the shoulder or elbow

Aims

The primary aim of this study was to develop a reliable, effective radiological score to assess the healing of humeral shaft fractures, the Radiographic Union Score for HUmeral fractures (RUSHU). The secondary aim was to assess whether the six-week RUSHU was predictive of nonunion at six months after the injury.

The primary aim of this study was to identify risk factors for developing neuritis and its impact on outcome following open reduction internal fixation (ORIF) of distal humerus fractures. Patients were identified from a prospective trauma database (1995–2010). All fractures of the distal humerus (OA-OTA Type A, B, C) managed with ORIF were included. Prospective long-term follow up was collected by telephone. Demographic data, fracture classification, intraoperative details (time to surgery, tourniquet, approach, fixation technique, nerve transposition), subsequent surgeries, presence of postoperative nerve palsy, complications and range of motion were collected. The Broberg and Morrey Elbow Score and DASH score were used as functional outcome measures. Eighty-two patients, mean age 50(range, 13–93) were included. 16% (13/82) developed post-operative ulnar neuritis, 7% (6/82) radial neuritis and 5% (4/82) longterm nonspecific dysaesthesia. Short-term (mean 10 months, range 1–120, collected in 82 patients) and long-term (mean 6 years, range 4–18, collected in 45%, 34/75, of living patients) was completed. In patients with nerve complication: average Broberg and Morrey score was 86 (76% good/excellent), average DASH was 24.7(range, 3.3–100) and Oxford Elbow Score was 39.5(range, 18–48). Compared to: 94 (96% good/excellent), 17.7(range, 0–73.3) and 43.8(range, 17–48) in patients without. Mean pain score was 3.7 in patients with nerve complication compared to 2 without. Nerve complications were seen with increased frequency in young, male patients with high energy and Type C injuries. Nerve complication following ORIF of distal humerus fractures is relatively common. They have detrimental impact on functional outcome. Certain groups appear to be at increased risk

In 1980, we developed a specially designed brace for treating supracondylar fractures of the humerus in children, along with an easy and safe technique of reduction by skeletal traction. This method, which takes into consideration only the medial tilting and anterior angulation of the distal fragment, achieves complete reduction, ignoring any lateral, posterior and minor rotational displacements of the fragment. Skeletal traction is applied through a screw inserted into the olecranon and the angulation at the fracture site is reduced regardless of the anatomical position without manipulation. We treated 193 children with displaced supracondylar fractures of the humerus using this method between 1980 and 2001. Only four children (2%) developed cubitus varus. The majority obtained an excellent range of movement at the elbow; one had a 25° limitation of flexion. This technique is an effective and easy method of treating supracondylar fractures of the humerus in children

In this study, we describe a morphological classification for greater tuberosity fractures of the proximal humerus. We divided these fractures into three types: avulsion, split and depression. We retrospectively reviewed all shoulder radiographs showing isolated greater tuberosity fractures in a Level I trauma centre between July 2007 and July 2012. We identified 199 cases where records and radiographs were reviewed and included 79 men and 120 women with a mean age of 58 years (23 to 96). The morphological classification was applied to the first 139 cases by three reviewers on two occasions using the Kappa statistic and compared with the AO and Neer classifications. The inter- and intra-observer reliability of the morphological classification was 0.73 to 0.77 and 0.69 to 0.86, respectively. This was superior to the Neer (0.31 to 0.35/0.54 to 0.63) and AO (0.30 to 0.32/0.59 to 0.65) classifications. The distribution of avulsion, split and depression type fractures was 39%, 41%, and 20%, respectively. This classification of greater tuberosity fractures is more reliable than the Neer or AO classifications. These distinct fracture morphologies are likely to have implications in terms of pathophysiology and surgical technique. Cite this article: Bone Joint J 2014;96-B:646–51

Aims. The PROximal Fracture of the Humerus Evaluation by Randomisation (PROFHER) randomised clinical trial compared the operative and non-operative treatment of adults with a displaced fracture of the proximal humerus involving the surgical neck. The aim of this study was to determine the long-term treatment effects beyond the two-year follow-up. Patients and Methods. Of the original 250 trial participants, 176 consented to extended follow-up and were sent postal questionnaires at three, four and five years after recruitment to the trial. The Oxford Shoulder Score (OSS; the primary outcome), EuroQol 5D-3L (EQ-5D-3L), and any recent shoulder operations and fracture data were collected. Statistical and economic analyses, consistent with those of the main trial were applied. Results. OSS data were available for 164, 155 and 149 participants at three, four and five years, respectively. There were no statistically or clinically significant differences between operative and non-operative treatment at each follow-up point. No participant had secondary shoulder surgery for a new complication. Analyses of EQ-5D-3L data showed no significant between-group differences in quality of life over time. Conclusion. These results confirm that the main findings of the PROFHER trial over two years are unchanged at five years. Cite this article: Bone Joint J 2017;99-B:383–92
