The April 2012 Trauma Roundup³⁶⁰ looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries

The February 2015 Children’s orthopaedics Roundup³⁶⁰ looks at: Hip dislocation in children with CTEV: two decades of experience; Population-based prevention of DDH in cerebral palsy: 20 years’ experience; Shoulder derotation in congenital plexus palsy; Back pain in the paediatric population: could MRI be the answer?; Intercondylar fracture of the humerus in children; The Dunn osteotomy in SUFE; Radiocapitellar line a myth!; Do ‘flatfooted’ children suffer?

We present a retrospective study of patients suffering from a variety of benign tumours in whom external fixators were used to treat deformity and limb-length discrepancy, and for the reconstruction of bone defects. A total of 43 limbs in 31 patients (12 male and 19 female) with a mean age of 14 years (2 to 54) were treated.

The diagnosis was Ollier’s disease in 12 limbs, fibrous dysplasia in 11, osteochondroma in eight, giant cell tumour in five, osteofibrous dysplasia in five and non-ossifying fibroma in two. The lesions were treated in the tibia in 19 limbs, in the femur in 16, and in the forearm in eight. The Ilizarov frame was used in 25 limbs, the Taylor Spatial Frame in seven, the Orthofix fixator in six, the Monotube in four and the Heidelberg fixator in one. The mean follow-up was 72 months (22 to 221).

The mean external fixation period was 168 days (71 to 352). The mean external fixation index was 42 days/cm (22.2 to 102.0) in the 22 patients who required limb lengthening. The mean correction angle for those with angular deformity was 23° (7° to 45°).

At final follow-up all patients had returned to normal activities. Four patients required a second operation for recurrent deformity of further limb lengthening. Local recurrence occurred in one patient, requiring further surgery.

Periprosthetic fractures are an increasingly common complication following joint replacement. The principles which underpin their evaluation and treatment are common across the musculoskeletal system. The Unified Classification System proposes a rational approach to treatment, regardless of the bone that is broken or the joint involved.

We present a retrospective study of 25 patients treated by open arthrolysis of the elbow for post-traumatic stiffness. The mean follow-up was for 7.8 years (5 to 10.8). The range of movement of the elbow, pain scores and functional outcomes were recorded pre- and postoperatively. An improvement in the mean range of movement from 55° (0° to 95°) to 105° (55° to 135°) was obtained in our patients at one year. This improvement was maintained over the mean follow-up period of 7.8 years (5 to 10.8). Improvement in pain, function and patient satisfaction was recorded in 23 of the 25 patients at final follow-up.

On the basis of this study, we believe that the results of open arthrolysis for post-traumatic stiffness of the elbow are durable over the medium term.

Several techniques are available for the treatment of displaced fractures of the neck of the radius in children. We report our experience in 14 children treated by indirect reduction and fixation using an elastic stable intramedullary nail. The patients were followed up for a mean of 28 months. One developed asymptomatic avascular necrosis. The rest had excellent results. One had a neuropraxia of the posterior interosseous nerve, which recovered within six weeks. We advocate elastic stable intramedullary nailing for the closed reduction and fixation of these fractures in children.

Things have not been quiet in the Cochrane Collaboration in the four months since the last 'Cochrane Corner', with the publication of six new or updated reviews summarised here, all conducted with the bulletproof Collaboration's methodology representing the pinnacle of evidence relevant to orthopaedic surgeons.

The October 2013 Children’s orthopaedics Roundup³⁶⁰ looks at: Half a century of Pavlik treatment; Step away from the child!: trends in fracture management; Posterolateral rotatory elbow instability in children; Osteochondral lesions undiagnosed in patellar dislocations; Oral bisphosphonates in osteogenesis imperfecta; Crossed or parallel pins in supracondylar fractures?; Not too late nor too early: getting epiphysiodesis right; Fixation of supramalleolar osteotomies.

Lateral epicondylitis, or ’tennis elbow’, is a common condition that usually affects patients between 35 and 55 years of age. It is generally self-limiting, but in some patients it may continue to cause persistent symptoms, which can be refractory to treatment. This review discusses the mechanism of disease, symptoms and signs, investigations, current management protocols and potential new treatments.

We report the results of six trauma and orthopaedic projects to Kenya in the last three years. The aims are to deliver both a trauma service and teaching within two hospitals; one a district hospital near Mount Kenya in Nanyuki, the other the largest public hospital in Kenya in Mombasa. The Kenya Orthopaedic Project team consists of a wide range of multidisciplinary professionals that allows the experience to be shared across those specialties. A follow-up clinic is held three months after each mission to review the patients. To our knowledge there are no reported outcomes in the literature for similar projects.

A total of 211 operations have been performed and 400 patients seen during the projects. Most cases were fractures of the lower limb; we have been able to follow up 163 patients (77%) who underwent surgical treatment. We reflect on the results so far and discuss potential improvements for future missions.

The type II Monteggia (posterior) lesion is a rare injury which is sometimes associated with ulnohumeral instability. We have reviewed 23 of 28 patients with this injury. A clinical and radiographic assessment was undertaken at follow-up. Functional outcome scores, including the Broberg and Morrey Index and the Disabilities of the Arm, Shoulder or Hand (DASH), were used. The results from the six patients with associated posterior ulnohumeral dislocation were compared with 17 without ulnohumeral injury. Those with dislocation had reduced movement of the elbow and had outcome scores indicative of greater disability compared to those without associated dislocation.

Local corticosteroid infiltration is a common practice of treatment for lateral epicondylitis. In recent studies no statistically significant or clinically relevant results in favour of corticosteroid injections were found. The injection of autologous blood has been reported to be effective for both intermediate and long-term outcomes. It is hypothesised that blood contains growth factors, which induce the healing cascade.

Most patients with a nightstick fracture of the ulna are treated conservatively. Various techniques of immobilisation or early mobilisation have been studied. We performed a systematic review of all published randomised controlled trials and observational studies that have assessed the outcome of these fractures following above- or below-elbow immobilisation, bracing and early mobilisation. We searched multiple electronic databases, related bibliographies and other studies. We included 27 studies comprising 1629 fractures in the final analysis. The data relating to the time to radiological union and the rates of delayed union and nonunion could be pooled and analysed statistically.

We found that early mobilisation produced the shortest radiological time to union (mean 8.0 weeks) and the lowest mean rate of nonunion (0.6%). Fractures treated with above- or below-elbow immobilisation and braces had longer mean radiological times to union (9.2 weeks, 9.2 weeks and 8.7 weeks, respectively) and higher mean rates of nonunion (3.8%, 2.1% and 0.8%, respectively). There was no statistically significant difference in the rate of non- or delayed union between those treated by early mobilisation and the three forms of immobilisation (p = 0.142 to p = 1.000, respectively). All the studies had significant biases, but until a robust randomised controlled trial is undertaken the best advice for the treatment of undisplaced or partially displaced nightstick fractures appears to be early mobilisation, with a removable forearm support for comfort as required.

This is a retrospective review of the results of the Acclaim total elbow replacement in 11 older patients aged ≥ 65 years with primary osteoarthritis of the elbow, with a mean follow-up of 57.6 months (30 to 86.4).

Significant reductions in pain and improvement in range of movement and function were recorded. Radiological review revealed two patients with 1 mm lucencies in a single zone, and one patient with 1 mm lucencies in two zones. No components required revision. There were no deep infections, dislocations or mechanical failures. Complications included one intra-operative medial condylar fracture and one post-operative transient ulnar neuropathy, which resolved.

This study demonstrates that the Acclaim prosthesis provides good symptomatic relief and improvement of function in patients with primary osteoarthritis, with low rates of loosening or other complications. This prosthesis can therefore be considered for patients aged ≥ 65 years with primary osteoarthritis of the elbow.

A pronation deformity of the forearm following an obstetric brachial plexus injury causes functional and cosmetic disability. We evaluated the results of pronator teres transfer to correct their deformity in 14 children treated over a period of four years. The mean age at surgery was 7.6 years (5 to 15). The indication for surgery in each case was impairment of active supination in a forearm that could be passively supinated provided that there was no medial contracture of the shoulder and normal function of the hand. The median follow-up was 20.4 months (8 to 42). No patient was lost to follow-up. Qualitative results were also assessed. The median active supination improved from 5° (0° to 10°) to 75° (70° to 80°) with no loss of pronation.

A passively correctible pronation contracture can be corrected safely and effectively by the transfer of pronator teres.

Between 1982 and 1997, 403 consecutive patients (522 elbows) with rheumatoid arthritis underwent Souter-Strathclyde total elbow replacement. By the end of 2007, there had been 66 revisions for aseptic loosening in 60 patients. The mean time of follow-up was 10.6 years (0 to 25) The survival rates at five-, ten, 15 and 19 years were 96% (95%, confidence interval (CI) 95 to 98), 89% (95% CI 86 to 92), 83% (95% CI 78 to 87), and 77% (95% CI 69 to 85), respectively. The small and medium-sized short-stemmed primary humeral components had a 5.6-fold and 3.6-fold risk of revision for aseptic loosening respectively, compared to the medium-sized long-stemmed component. The small and medium-sized all-polyethylene ulnar components had respectively a 28.2-fold and 8.4-fold risk of revision for aseptic loosening, compared to the metal-backed ulnar components.

The use of retentive ulnar components was not associated with an increased risk of aseptic loosening compared to non-retentive implants.

We have investigated the anatomy of the proximal part of the ulna to assess its influence on the use of plates in the management of fractures at this site. We examined 54 specimens from cadavers. The mean varus angulation in the proximal third was 17.5° (11° to 23°) and the mean anterior deviation 4.5° (1° to 14°). These variations must be considered when applying plates to the dorsal surface of the ulna for Monteggia-type fractures. A pre-operative radiograph of the contralateral elbow may also be of value.

We reviewed the clinical and radiological results of six patients who had sustained traumatic separation of the distal epiphysis of the humerus at birth.

The correct diagnosis was made from plain radiographs and often supplemented with ultrasonography, MRI and arthrography. An orthopaedic surgeon saw two patients within two days of birth, and the other four were seen at between nine and 30 days. The two neonates underwent unsuccessful attempts at closed reduction. In the remaining patients, seen after the age of eight days, no attempt at reduction was made. All six displaced fractures were immobilised in a cast with the elbow at 90° of flexion and the forearm pronated.

When seen at a mean of 58 months (16 to 120) after injury, the clinical and radiological results were excellent in five patients, with complete realignment of the injury. In one patient the forearm lay in slightly reduced valgus with the elbow in full extension.

Traumatic separation of the distal epiphysis of the humerus may be missed on the maternity wards and not diagnosed until after discharge from hospital. However, even when no attempt is made to reduce the displaced epiphysis, a good clinical result can be expected.
