Aims

The aim of this study was to compare the cost-effectiveness of surgical fixation with Kirschner (K-)wire ersus moulded casting after manipulation of a fracture of the distal radius in an operating theatre setting.

We present a method of manipulative reduction, immobilisation and fixation using a U-shaped plaster with the elbow in extension for extension-type supracondylar fractures of the humerus in children. When the elbow is in full extension, both the extensor and the flexor muscles are neutralised during manipulative reduction and the carrying angle can be easily assessed thus preventing cubitus varus, the most common complication.

In order to evaluate the efficiency of this method, we compared the clinical results of the new method with those of conventional treatment. In a group of 95 children who sustained an extension-type supracondylar fracture of the humerus, 49 were treated by the new method and 46 by the conventional method, reduction and immobilisation in a plaster slab with the elbow in flexion.

Reduction and immobilisation were easily achieved and reliably maintained by one manipulation for all the children treated by the new method. In 12 children treated by the conventional method, the initial reduction failed and in seven secondary displacement of the distal fragment occurred during the period of immobilisation in plaster. All required a second or third manipulation. Of the 46 children, 28 (60.9%) had developed cubitus varus at a mean follow-up of 4.6 years when treated by the conventional method. None of the children treated by the new method developed cubitus varus. The mean score, according to the Hospital for Special Surgery (HSS) elbow scoring system, was 91 points using the new method and 78 with the conventional method. The results were statistically significant with regard to the incidence of cubitus varus and the elbow score (p < 0.01) suggesting that the new method is reliable and gives a satisfactory outcome.

We examined differences in the rate of open reduction, operating time, length of hospital stay and outcome between two groups of children with displaced supracondylar fractures of the humerus who underwent surgery either within 12 hours of the injury or later.

There were 77 children with type-3 supracondylar fractures. Of these, in 43 the fracture was reduced and pinned within 12 hours and in 34 more than 12 hours after injury. Both groups were similar in regard to gender, age and length of follow-up. Bivariate and logistical regression analysis showed no statistical difference between the groups. The number of peri-operative complications was low and did not affect the outcome regardless of the timing of treatment.

Our study confirmed that the treatment of uncomplicated displaced supracondylar fractures of the humerus can be early or delayed. In these circumstances operations at night can be avoided.

Displaced extension supracondylar fractures of the elbow 1. One hundred and ten children were treated by reduction and stabilisation by two pins inserted laterally at an angle of 30 degrees to one another. 2. The complications before and after treatment included fifteen nerve lesions in thirteen patients. The ulnar nerve was involved on one occasion only. Solitary radial nerve injuries occurred with postero-medial displacement of the distal fragment, while median nerve and brachial artery injuries were associated with postero-lateral displacement. All the lesions recovered spontaneously. 3. There were no ischaemic complications after treatment, despite the ligation of one ruptured brachial artery. 4. The average stay in hospital was four days, compared with twenty days for thirty-two other patients treated in traction because of gross oedema. 5. Of eighty patients seen six months to five years after the fracture, seventy (or 87·5 per cent) had excellent or good results, seven patients with marked varus deformities had fair results, and two patients had poor results with very stiff elbows. Displaced flexion fractures 1. The clinical features, complications and treatment of seventeen cases are described. 2. There were no complications involving the median or radial nerves or the brachial artery, but three patients had a lesion of the ulnar nerve. 3. Nine children had closed reduction and fixation by two lateral percutaneous pins. 4. Reduction was difficult and the results poor compared with extension fractures. Closed reduction failed in one-third of the children, and the functional and cosmetic results were unsatisfactory in over half the patients reviewed

We describe a method of pinning extension supracondylar fractures of the humerus in children. Following closed reduction, a posterior intrafocal wire is inserted and a second lateral wire added when needed for rotational stability. Between May 2002 and November 2005 we performed this technique in 69 consecutive patients. A single posterior wire was used in 29 cases, and two wires in 40. The mean follow-up was two years (21 to 30 months). The results were assessed according to Flynn’s criteria. In the single-wire group there were 21 excellent, five good and one poor result. Two patients were lost to follow-up. In the two-wire group there were 32 excellent, two good and three poor results. Three were lost to follow-up. The poor results were due to a failure to achieve adequate reduction, fixation or both. We conclude that the intact posterior periosteal hinge can be used successfully in the clinical situation, giving results that compare well with other techniques of pinning. The posterior route offers an attractive alternative method for fixation of supracondylar fractures of the humerus in children

Aims

We aimed to compare the implant survival, complications, readmissions, and mortality of Vancouver B2 periprosthetic femoral fractures (PFFs) treated with internal fixation with that of B1 PFFs treated with internal fixation and B2 fractures treated with revision arthroplasty.

We report the results of 116 consecutive displaced extension supracondylar fractures of the elbow in children treated during the first two years after the introduction of the following protocol; closed reduction under general anaesthesia with fluoroscopic control and lateral percutaneous pinning using two parallel pins or, when closed reduction failed, open reduction and internal fixation by cross-pinning. Eight patients were lost to follow-up during the first postoperative year. The mean follow-up for the remaining 108 was 27.9 months (12 to 47, median 26.5). At the final follow-up, using Flynn’s overall modified classification, the clinical result was considered to be excellent in 99 patients (91.6%), good in five (4.6%) and poor in four (3.7%). All the poor results were due to a poor cosmetic result, but had good or excellent function. Technical error in the initial management of these four cases was thought to be the cause of the poor results. The protocol described resulted in good or excellent results in 96% of our patients, providing a safe and efficient treatment for displaced supracondylar fractures of the humerus even in less experienced hands

Aims

Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful.

Aims

The aim of this study was to assess the feasibility of conducting a full-scale, appropriately powered, randomized controlled trial (RCT) comparing internal fracture fixation and distal femoral replacement (DFR) for distal femoral fractures in older patients.

Fractures of the proximal forearm in young children may be unstable with the elbow flexed but stable with it in extension. Fifteen such fractures were managed by immobilisation in long-arm casts with the elbow extended. Only one patient had more than 15 degrees angulation at the time of bony union. All obtained normal elbow movement at two weeks and full forearm rotation at follow-up. No casts fell off. The extended elbow cast is awkward but it provides an alternative to internal fixation for some unstable fractures

In two years we treated four women with ununited stress fractures of their proximal tibial diaphyses. They all had arthritis and valgus deformity. The stress fractures had been treated elsewhere by non-operative means in three patients and by open reduction and internal fixation in one, but had failed to unite. After treatment with a modular total knee prosthesis with a long tibial stem extension, all the fractures united. A modular total knee prosthesis is suitable for the rare and difficult problem of ununited tibial stress fractures in patients with deformed arthritic knees since it corrects the deformity and the adverse biomechanics at the fracture site, stabilises the fracture and treats the arthritis

It is unclear whether there is a limit to the amount of distal bone required to support fixation of supracondylar periprosthetic femoral fractures. This retrospective multicentre study evaluated lateral locked plating of periprosthetic supracondylar femoral fractures and compared the results according to extension of the fracture distal with the proximal border of the femoral prosthetic component. Between 1999 and 2008, 89 patients underwent lateral locked plating of a supracondylar periprosthetic femoral fracture, of whom 61 patients with a mean age of 72 years (42 to 96) comprising 53 women, were available after a minimum follow-up of six months or until fracture healing. Patients were grouped into those with fractures located proximally (28) and those with fractures that extended distal to the proximal border of the femoral component (33). Delayed healing and nonunion occurred respectively in five (18%) and three (11%) of more proximal fractures, and in two (6%) and five (15%) of the fractures with distal extension (p = 0.23 for delayed healing; p = 0.72 for nonunion, Fisher’s exact test). Four construct failures (14%) occurred in more proximal fractures, and three (9%) in fractures with distal extension (p = 0.51). Of the two deep infections that occurred in each group, one resolved after surgical debridement and antibiotics, and one progressed to a nonunion. Extreme distal periprosthetic supracondylar fractures of the femur are not a contra-indication to lateral locked plating. These fractures can be managed with internal fixation, with predictable results, similar to those seen in more proximal fractures

A prospective study was made over a three-year period of 900 consecutive unilateral Colles' fractures. The radiographic features at the time of fracture, after reduction and one week later were measured and correlated with grip strength and range of movement at three years. The most significant radiographic feature to influence the outcome was the presence of shortening of the radius one week after reduction of the fracture. Persistent dorsal tilt, radiocarpal joint involvement and ulnar styloid fracture were each associated with reduced range of movement, but had no effect on grip strength. Extension of the fracture into the distal radio-ulnar joint was associated with reduced grip strength but had no effect on range of movement. Radial tilt of the radial fragment did not correlate with any aspect of the result after three years

Aims

Supracondylar fractures are the most frequently occurring paediatric fractures about the elbow and may be associated with a neurovascular injury. The British Orthopaedic Association Standards for Trauma 11 (BOAST 11) guidelines describe best practice for supracondylar fracture management. This study aimed to assess whether emergency departments in the United Kingdom adhere to BOAST 11 standard 1: a documented assessment, performed on presentation, must include the status of the radial pulse, digital capillary refill time, and the individual function of the radial, median (including the anterior interosseous), and ulnar nerves.

Aims

There has been an evolution recently in the management of unstable fractures of the ankle with a trend towards direct fixation of a posterior malleolar fragment. Within these fractures, Haraguchi type 2 fractures extend medially and often cannot be fixed using a standard posterolateral approach. Our aim was to describe the posteromedial approach to address these fractures and to assess its efficacy and safety.

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.

We compared two management strategies for the perfused but pulseless hand after stabilisation of a Gartland type III supracondylar fracture. We identified 19 patients, of whom 11 were treated conservatively after closed reduction (group 1). Four required secondary exploration, of whom three had median and/or anterior interosseus nerve palsy at presentation. All four were found to have tethering or entrapment of both nerve and vessel at the fracture site. Only two regained patency of the brachial artery, and one patient has a persistent neurological deficit.

In six of the eight patients who were explored early (group 2) the vessel was tethered at the fracture site. In group 2 four patients also had a nerve palsy at presentation and were similarly found to have tethering or entrapment of both the nerve and the vessel. The patency of the brachial artery was restored in all six cases and their neurological deficits recovered completely.

We would recommend early exploration of a Gartland type III supracondylar fracture in patients who present with a coexisting anterior interosseous or median nerve palsy, as these appear to be strongly predictive of nerve and vessel entrapment.

Few studies have examined the order in which a spinal osteotomy and total hip replacement (THR) are to be performed for patients with ankylosing spondylitis. We have retrospectively reviewed 28 consecutive patients with ankylosing spondylitis who underwent both a spinal osteotomy and a THR from September 2004 to November 2012. In the cohort 22 patients had a spinal osteotomy before a THR (group 1), and six patients had a THR before a spinal osteotomy (group 2). The mean duration of follow-up was 3.5 years (2 to 9). The spinal sagittal Cobb angle of the vertebral osteotomy segment was corrected from a pre-operative kyphosis angle of 32.4 (SD 15.5°) to a post-operative lordosis 29.6 (SD 11.2°) (p < 0.001). Significant improvements in pain, function and range of movement were observed following THR. In group 2, two of six patients had an early anterior dislocation. The spinal osteotomy was performed two weeks after the THR. At follow-up, no hip has required revision in either group. Although this non-comparative study only involved a small number of patients, given our experience, we believe a spinal osteotomy should be performed prior to a THR, unless the deformity is so severe that the procedure cannot be performed.

Most hip fractures treated with modern internal fixation techniques will heal. However, failures occasionally occur and require revision procedures. Salvage strategies employed during revision are based on whether the fixation failure occurs in the femoral neck, or in the intertrochanteric region. Patient age and remaining bone stock also influence decision making. For fractures in young patients, efforts are generally focused on preserving the native femoral head via osteotomies and repeat internal fixation. For failures in older patients, some kind of hip replacement is usually selected. Disuse osteopenia, deformity, bone loss, and stress-risers from previous internal fixation devices all pose technical challenges to successful reconstruction. Attention to detail is important in order to minimise complications. In the majority of cases, good outcomes have been reported for the various salvage strategies.
