Fracture-dislocations of the tarsometatarsal (Lisfranc) joints are frequently overlooked or misdiagnosed at initial presentation. This is a comparative cohort study over a period of five years comparing primary open reduction and internal fixation in 22 patients (23 feet) with secondary corrective arthrodesis in 22 patients (22 feet) who presented with painful malunion at a mean of 22 months (1.5 to 45) after injury. In the first group primary treatment by open reduction and internal fixation for eight weeks with Kirschner-wires or screws was undertaken, in the second group treatment was by secondary corrective arthrodesis. There was one deep infection in the first group. In the delayed group there was one complete and one partial nonunion. In each group 20 patients were available for follow-up at a mean of 36 months (24 to 89) after operation. The mean American Orthopaedic Foot and Ankle Society midfoot score was 81.4 (62 to 100) after primary treatment and 71.8 (35 to 88) after corrective arthrodesis (t-test; p = 0.031). We conclude that primary treatment by open reduction and internal fixation of tarsometatarsal fracture-dislocations leads to improved functional results, earlier return to work and greater patient satisfaction than secondary corrective arthrodesis, which remains a useful salvage procedure providing significant relief of pain and improvement in function

A retrospective study of 23 acetabular fractures in patients up to 17 years of age is presented, with an average follow-up of eight years. Good or excellent functional results were achieved in 21 patients; radiographic results were good or excellent in 16. Conservative treatment gave consistently good results in fractures with minimal initial displacement, stable posterior fracture-dislocations and Salter-Harris type 1 and 2 triradiate cartilage fractures. Less favourable results were seen in type 5 triradiate cartilage fractures and in comminuted fractures, but operation was no better. Unstable posterior fracture-dislocations and irreducible central fracture-dislocations need operative treatment but the results may still be unsatisfactory

Fractures of the proximal interphalangeal joint include a wide spectrum of injuries, from stable avulsion fractures to complex fracture-dislocations. Stability of the joint is paramount in determining the appropriate treatment, which should aim to facilitate early mobilisation and restoration of function

We performed a comprehensive systematic review of the literature to examine the role of hemiarthroplasty in the early management of fractures of the proximal humerus. In all, 16 studies dealing with 810 hemiarthroplasties in 808 patients with a mean age of 67.7 years (22 to 91) and a mean follow-up of 3.7 years (0.66 to 14) met the inclusion criteria. Most of the fractures were four-part fractures or fracture-dislocations. Several types of prosthesis were used. Early passive movement on the day after surgery and active movement after union of the tuberosities at about six weeks was described in most cases. The mean active anterior elevation was to 105.7° (10° to 180°) and the mean abduction to 92.4° (15° to 170°). The incidence of superficial and deep infection was 1.55% and 0.64%, respectively. Complications related to the fixation and healing of the tuberosities were observed in 86 of 771 cases (11.15%). The estimated incidence of heterotopic ossification was 8.8% and that of proximal migration of the humeral head 6.8%. The mean Constant score was 56.63 (11 to 98). At the final follow-up, no pain or only mild pain was experienced by most patients, but marked limitation of function persisted

Unstable pelvic injuries in young children with an immature pelvis have different modes of failure from those in adolescents and adults. We describe the pathoanatomy of unstable pelvic injuries in these children, and the incidence of associated avulsion of the iliac apophysis and fracture of the ipsilateral fifth lumbar transverse process (L5-TP). We retrospectively reviewed the medical records of 33 children with Tile types B and C pelvic injuries admitted between 2007 and 2014; their mean age was 12.6 years (2 to 18) and 12 had an immature pelvis. Those with an immature pelvis commonly sustained symphyseal injuries anteriorly with diastasis, rather than the fractures of the pubic rami seen in adolescents. Posteriorly, transsacral fractures were more commonly encountered in mature children, whereas sacroiliac dislocations and fracture-dislocations were seen in both age groups. Avulsion of the iliac apophysis was identified in eight children, all of whom had an immature pelvis with an intact ipsilateral L5-TP. Young children with an immature pelvis are more susceptible to pubic symphysis and sacroiliac diastasis, whereas bony failures are more common in adolescents. Unstable pelvic injuries in young children are commonly associated with avulsion of the iliac apophysis, particularly with displaced SI joint dislocation and an intact ipsilateral L5-TP.

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

1. A review of fifty-eight posterior dislocations or fracture-dislocations of the hip is presented. 2. With few exceptions, patients were treated by immediate reduction of the dislocation under general anaesthesia, traction for six weeks and avoidance of weight-bearing for a further six weeks. 3. The results are discussed with reference to the age of the patient, length of follow-up, side affected and type of dislocation. 4. As a result ofthis review, we propose to reduce the period oftreatment in Type I dislocations (posterior dislocation without fracture) and to continue a conservative policy in respect to treatment and reconstructive hip surgery in Types II and HI fracture-dislocations

1. Paraplegia from fracture-dislocation at the thoraco-lumbar junction is a mixed cord and root injury. The root damage can be distinguished from cord damage by neurological examination and by comparison of the neurological level with the fracture level. 2. Even though the cord injury is complete, as it usually is, the roots often escape or recover. 3. Fracture-dislocations can be divided into stable and unstable types. Because of the possibility of root recovery care must be taken to prevent further damage to the roots by manipulation of the spine or during treatment. For this reason unstable fracture-dislocations are fixed internally by plates. 4. Internal fixation also assists in the nursing of the patient. The nursing technique and the care of the bladder are described

We have reviewed the early complications of 121 surgically treated closed ankle fractures; the complication rate was 30%, with 14 major and 22 minor complications. Fractures with skin blisters or abrasions had more than double the overall complication rate. Fracture-dislocations had three times as many major complications as simple fractures, and those not fixed within 24 hours had a 44% major complication rate compared to 5.3% in those operated upon as emergencies. Patients transferred from another medical facility had high complication rates, especially if they had fracture-dislocations. We conclude that operative treatment of ankle fractures must be delivered in a timely fashion, especially in severe fractures. We would caution against the practice of transferring patients with serious ankle fractures before completion of definitive care

1. Fifty-eight major injuries in the region of the talus were reviewed regarding treatment, incidence of complications and long-term results. 2. The prognosis for simple fractures of the head, neck or body was good, as was that for dislocations of the midtarsal and peritalar joints. 3. The prognosis for fracture-dislocations of the neck and body was better than has been frequently reported. It was related to the degree of initial trauma. A good result occurs only if accurate reduction is effected and maintained. Fixation with a Kirschner wire is a useful method of maintaining the reduction after unstable fracture-dislocations. 4. Avascular necrosis occurred only in the more severe injuries and its incidence was related to the degree of initial displacement. The late results were better than have been previously described. The condition is best treated conservatively by protection from weight-bearing until revascularisation is well advanced. 5. A case with an unusual pattern of fracture of the neck of the talus is described following a plantar-flexion inversion injury

1. Fifty dislocations and fracture-dislocations of the pelvis have been reviewed. 2. Complications were unusual. Two patients with rupture of the bladder died; two with rupture of the urethra survived. Of eight patients with retroperitoneal haemorrhage four died; the treatment advised is controlled blood transfusion maintaining a blood-pressure of not more than 100 mm. 3. Two types of pelvic disruption should be distinguished: 1) pubic injury with sacro-iliac dislocation; 2) pubic injury with fracture near the sacro-iliac joint. The first is twice as common as the second. 4. In each type, displacement is maintained by extension of the hip and outward roll of the limb. This may be controlled by the Watson-Jones plaster method but the pelvic sling technique is preferred and was used in all cases in this series. 5. The prognosis in fracture-dislocations is very good; nearly all patients went back to heavy work. 6. The prognosis in sacro-iliac dislocations is not so good; only half the patients went back to heavy work and there was often persistent sacro-iliac pain. Sacro-iliac arthrodesis is advised in those cases

Aims

This study aimed to answer the following questions: do 3D-printed models lead to a more accurate recognition of the pattern of complex fractures of the elbow?; do 3D-printed models lead to a more reliable recognition of the pattern of these injuries?; and do junior surgeons benefit more from 3D-printed models than senior surgeons?

1. Experimental radiological and mechanical studies on a cadaveric cervical spine are reported. 2. A series of fifty-nine dislocations and fracture-dislocations of the cervical spine is reviewed. 3. The methods of reduction and indications for operation are discussed

The results of a prospective multicentre study of the Herbert differential pitch bone screw used to treat 50 scaphoid fractures and non-unions are presented. All fresh fractures and four of the five fracture-dislocations united, an overall union rate of 92%. Although the technique is demanding, the Herbert screw can achieve excellent results in the management of scaphoid fractures

Eight children with missed Monteggia fracture-dislocations are described. Seven had reconstructive surgery which included resection of scar tissue from the radiohumeral joint, proximal ulnar osteotomy, reduction of the radial head and reconstruction of the annular ligament. One had excision of the radial head. Excellent results were obtained in patients under ten years of age, up to four years after the initial injury

The term Volkmann’s triangle for the avulsed posterior edge of the tibia in fracture-dislocations of the ankle is incorrect. Volkmann did not publish any articles relating to the posterior edge of the tibia. Credit should go to Henry Earle, who was an outstanding British surgeon of the first half of 19th century. He described avulsion of the posterior edge of the tibia in 1828. In 1823 he also published a monograph entitled Practical observations in surgery in which he described a specially designed bed for the conservative treatment of proximal fractures of the femur

We retrospectively reviewed 20 patients at three to 19 years after displaced anterior fracture-dislocations of the hip. Eighteen of them were treated by traction, after ensuring that the femoral head was adequately reduced beneath the undisrupted part of the weight-bearing dome. Two required operation. Although none of the 18 conservatively treated fractures was reduced anatomically, the results were good in ten patients and excellent in the seven in whom the fracture did not involve the weight-bearing dome. We conclude that anterior column fractures have a favourable prognosis after conservative treatment

A retrospective survey of 135 posterior dislocations and fracture-dislocations of the hip was carried out in order to define the pattern of associated knee injuries. Thirty-five patients had sustained a significant injury to the knee, of which twenty-five were clearly attributable to a direct blow on the front of the knee (fractured patella, traumatic chondromalacia, fractures of femoral and tibial condyles) and ten were compatible with valgus, yams or rotational forces (medial, lateral and cruciate ligament tears). The second type of injury has not been widely recognised but it is important that it should not be overlooked
