Injuries to the acromioclavicular joint are common but underdiagnosed. Sprains and minor subluxations are best managed conservatively, but there is debate concerning the treatment of complete dislocations and the more complex combined injuries in which other elements of the shoulder girdle are damaged. Confusion has been caused by existing systems for classification of these injuries, the plethora of available operative techniques and the lack of well-designed clinical trials comparing alternative methods of management. Recent advances in arthroscopic surgery have produced an even greater variety of surgical options for which, as yet, there are no objective data on outcome of high quality. We review the current concepts of the treatment of these injuries

Aims . To analyse the influence of upper extremity trauma on the long-term outcome of polytraumatised patients. . Patients and Methods. A total of 629 multiply injured patients were included in a follow-up study at least ten years after injury (mean age 26.5 years, standard deviation 12.4). The extent of the patients’ injury was classified using the Injury Severity Score. Outcome was measured using the Hannover Score for Polytrauma Outcome (HASPOC), Short Form (SF)-12, rehabilitation duration, and employment status. Outcomes for patients with and without a fracture of the upper extremity were compared and analysed with regard to specific fracture regions and any additional brachial plexus lesion. Results. In all, 307 multiply-injured patients with and 322 without upper extremity injuries were included in the study. The groups with and without upper limb injuries were similar with respect to demographic data and injury pattern, except for midface trauma. There were no significant differences in the long-term outcome. In patients with brachial plexus lesions there were significantly more who were unemployed, required greater retraining and a worse HASPOC. Conclusion. Injuries to the upper extremities seem to have limited effect on long-term outcome in patients with polytrauma, as long as no injury was caused to the brachial plexus.

1. The literature on hyperextension injuries of the spine is briefly reviewed. 2. Such injuries in the cervical spine can be subdivided into five groups based on the pathological anatomy, based on the experience of fifty-one patients in the Spinal Injuries Centre for Victoria over the past five years. 3. Extension injuries of the thoraco-lumbar spine are discussed. They are rare and have a poor prognosis. 4. The importance of treatment based on sound clinical and pathological knowledge is emphasised, particularly in order that stable and unstable lesions may be recognised early and managed correctly

Sporting injuries around the ankle vary from simple sprains that will resolve spontaneously within a few days to severe injuries which may never fully recover and may threaten the career of a professional athlete. Some of these injuries can be easily overlooked altogether or misdiagnosed with potentially devastating effects on future performance. In this review article, we cover some of the common and important sporting injuries involving the ankle including updates on their management and outcomes.

Injuries involving the midtarsal joint, which are frequently misdiagnosed, have been studied to clarify the mechanism, classification and treatment. The necessity for routine antero-posterior, lateral and oblique radiographs is emphasised. Seventy-one injuries have been classified according to the direction of the deforming force : medial, longitudinal compression, lateral, plantar and crush types are described. Included in the medial and lateral types is a hitherto undescribed tarsal rotation or " swivel" injury. The mechanism whereby longitudinal compression causes fractures of the body of the navicular is described, and two varieties having different prognoses are defined : one due to purely longitudinal compression and the other due to longitudinal compression with a medial component. The results of treatment have been assessed clinically and radiologically. Reduction, open if necessary, with internal fixation, is recommended for displaced fractures : primary arthrodesis is not indicated. For severe persistent symptoms from medial and longitudinal force injuries triple arthrodesis is recommended, and from lateral force injuries, calcaneo-cuboid arthrodesis

1. Twenty cases of tarso-metatarsal joint injury have been studied with regard to the mechanism of injury, and experiments have been done on cadavers to confirm clinical impressions. 2. Injuries of the tarso-metatarsal joints occur by direct and indirect mechanisms, the latter being more common. 3. Indirect injuries occur in at least two ways-namely, acute abduction of the forefoot and plantar-flexion of the forefoot. 4. Most of the indirect injuries occur when the ankle joint is in a plantar-flexed position. 5. Whereas this foot injury once gained prominence on the field of battle amongst cavalrymen, it is currently associated with the motor car, the step ladder, the toboggan, the joy-rider, and commonly the simple misguided step

1. Injuries to the atlas and axis may occur at any age. They are usually not fatal. 2. In children spontaneous rotatory dislocation is the commonest type of lesion. In adults fracture of the odontoid process is more likely. 3. The spinal cord is often undamaged. In some cases complicated by cord damage the neurological disturbance is caused by an associated injury to the lower cervical spine. 4. Spinal cord damage may be immediate or delayed. 5. In cases of incomplete cord lesion there may be recovery of function after reduction of the displacement or without such reduction. 6. Diagnosis rests on the history and physical signs, and radiographic findings. Radiographs of this area require careful interpretation, and special radiographic techniques may he necessary. A normal radiograph does not necessarily exclude the possibility of atlanto-axial injury. 7. Though many patients would survive without treatment the initial discomfort and danger of complications demand that adequate protection be provided. In relatively minor injuries and in old people protection by a plaster collar may be sufficient. In some cases it is justifiable to undertake manipulation and apply a plaster. Cases with severe displacement require traction, preferably by skull calipers. Recurrent displacement, instability, and cord signs demand operative reduction and fusion. Satisfactory fusion of the atlas and axis alone is feasible, and good function is preserved. More extensive fusion of the cervical spine is seldom necessary

Injuries to the tarsometatarsal (Lisfranc) joint are not common, and the results of treatment are often unsatisfactory. Since no individual is likely to see many such injuries, we decided to make a retrospective study of patients from five different centres. In this way 119 patients with injuries of the Lisfranc joint have been collected. This paper classifies these injuries and describes their incidence, mechanism of production, methods of treatment, results and complications. Sixty-nine of the patients attended for review: 35 of these had been treated by closed methods, 27 had had an open reduction and seven patients had had no treatment. On the basis of our study we suggest that these injuries should be classified according to the type of injury rather than the nature of the deforming force and that their treatment be based upon this classification. It seems that, whatever the severity of the initial injury, prognosis depends on accurate reduction and its maintenance

The aim of this study was to report the pattern of severe open diaphyseal tibial fractures sustained by military personnel, and their orthopaedic–plastic surgical management.The United Kingdom Military Trauma Registry was searched for all such fractures sustained between 2006 and 2010. Data were gathered on demographics, injury, management and preliminary outcome, with 49 patients with 57 severe open tibial fractures identified for in-depth study. The median total number of orthopaedic and plastic surgical procedures per limb was three (2 to 8). Follow-up for 12 months was complete in 52 tibiae (91%), and half the fractures (n = 26) either had united or in the opinion of the treating surgeon were progressing towards union. The relationship between healing without further intervention was examined for multiple variables. Neither the New Injury Severity Score, the method of internal fixation, the requirement for vascularised soft-tissue cover nor the degree of bone loss was associated with poor bony healing. Infection occurred in 12 of 52 tibiae (23%) and was associated with poor bony healing (p = 0.008). This series characterises the complex orthopaedic–plastic surgical management of severe open tibial fractures sustained in combat and defines the importance of aggressive prevention of infection.

This is a case series of prospectively gathered data characterising the injuries, surgical treatment and outcomes of consecutive British service personnel who underwent a unilateral lower limb amputation following combat injury. Patients with primary, unilateral loss of the lower limb sustained between March 2004 and March 2010 were identified from the United Kingdom Military Trauma Registry. Patients were asked to complete a Short-Form (SF)-36 questionnaire. A total of 48 patients were identified: 21 had a trans-tibial amputation, nine had a knee disarticulation and 18 had an amputation at the trans-femoral level. The median New Injury Severity Score was 24 (mean 27.4 (9 to 75)) and the median number of procedures per residual limb was 4 (mean 5 (2 to 11)). Minimum two-year SF-36 scores were completed by 39 patients (81%) at a mean follow-up of 40 months (25 to 75). The physical component of the SF-36 varied significantly between different levels of amputation (p = 0.01). Mental component scores did not vary between amputation levels (p = 0.114). Pain (p = 0.332), use of prosthesis (p = 0.503), rate of re-admission (p = 0.228) and mobility (p = 0.087) did not vary between amputation levels.

These findings illustrate the significant impact of these injuries and the considerable surgical burden associated with their treatment. Quality of life is improved with a longer residual limb, and these results support surgical attempts to maximise residual limb length.

The management of injury to the distal tibiofibular syndesmosis remains controversial in the treatment of ankle fractures. Operative fixation usually involves the insertion of a metallic diastasis screw. There are a variety of options for the position and characterisation of the screw, the type of cortical fixation, and whether the screw should be removed prior to weight-bearing. This paper reviews the relevant anatomy, the clinical and radiological diagnosis and the mechanism of trauma and alternative methods of treatment for injuries to the syndesmosis.

In our study, the aims were to describe the changes in the appearance of the lumbar spine on MRI in elite fast bowlers during a follow-up period of one year, and to determine whether these could be used to predict the presence of a stress fracture of the posterior elements. We recruited 28 elite fast bowlers with a mean age of 19 years (16 to 24) who were training and playing competitively at the start of the study. They underwent baseline MRI (season 1) and further scanning (season 2) after one year to assess the appearance of the lumbar intervertebral discs and posterior bony elements. The incidence of low back pain and the amount of playing and training time lost were also recorded.

In total, 15 of the 28 participants (53.6%) showed signs of acute bone stress on either the season 1 or season 2 MR scans and there was a strong correlation between these findings and the later development of a stress fracture (p < 0.001). The prevalence of intervertebral disc degeneration was relatively low. There was no relationship between disc degeneration on the season 1 MR scans and subsequent stress fracture. Regular lumbar MR scans of asymptomatic elite fast bowlers may be of value in detecting early changes of bone stress and may allow prompt intervention aimed at preventing a stress fracture and avoiding prolonged absence from cricket.

We reviewed 101 patients with injuries of the terminal branches of the infraclavicular brachial plexus sustained between 1997 and 2009. Four patterns of injury were identified: 1) anterior glenohumeral dislocation (n = 55), in which the axillary and ulnar nerves were most commonly injured, but the axillary nerve was ruptured in only two patients (3.6%); 2) axillary nerve injury, with or without injury to other nerves, in the absence of dislocation of the shoulder (n = 20): these had a similar pattern of nerve involvement to those with a known dislocation, but the axillary nerve was ruptured in 14 patients (70%); 3) displaced proximal humeral fracture (n = 15), in which nerve injury resulted from medial displacement of the humeral shaft: the fracture was surgically reduced in 13 patients; and 4) hyperextension of the arm (n = 11): these were characterised by disruption of the musculocutaneous nerve. There was variable involvement of the median and radial nerves with the ulnar nerve being least affected.

Surgical intervention is not needed in most cases of infraclavicular injury associated with dislocation of the shoulder. Early exploration of the nerves should be considered in patients with an axillary nerve palsy without dislocation of the shoulder and for musculocutaneous nerve palsy with median and/or radial nerve palsy. Urgent operation is needed in cases of nerve injury resulting from fracture of the humeral neck to relieve pressure on nerves.

The integrity of the spinal accessory nerve is fundamental to thoracoscapular function and essential for scapulohumeral rhythm. This nerve is vulnerable along its superficial course. This study assessed the delay in diagnosis and referral for management of damage to this nerve, clarified its anatomical course and function, and documented the results of repair. From examination of our records, 111 patients with lesions of the spinal accessory nerve were treated between 1984 and 2007. In 89 patients (80.2%) the damage was iatropathic. Recognition and referral were seldom made by the surgeon responsible for the injury, leading to a marked delay in instituting treatment. Most referrals were made for painful loss of shoulder function. The clinical diagnosis is straightforward. There is a characteristic downward and lateral displacement of the scapula, with narrowing of the inferior scapulohumeral angle and loss of function, with pain commonly present. In all, 80 nerves were explored and 65 were repaired. The course of the spinal accessory nerve in relation to the sternocleidomastoid muscle was constant, with branches from the cervical plexus rarely conveying motor fibres. Damage to the nerve was predominantly posterior to this muscle.

Despite the delay, the results of repair were surprising, with early relief of pain, implying a neuropathic source, which preceded generally good recovery of muscle function.

Forty patients with a whiplash injury who had been reviewed previously 2 and 10 years after injury were assessed again after a mean of 15.5 years by physical examination, pain and psychometric testing.

Twenty-eight (70%) continued to complain of symptoms referable to the original accident. Neck pain was the commonest, but low-back pain was present in half. Women and older patients had a worse outcome. Radiating pain was more common in those with severe symptoms.

Evidence of psychological disturbance was seen in 52% of patients with symptoms. Between 10 and 15 years after the accident 18% of the patients had improved whereas 28% had deteriorated.

In the necropsy material presented there were, among 100 spinal injuries occurring during the past eight years, twelve in juveniles up to eighteen years of age. In all cases, the growth zone of the cartilaginous end-plate of the spine was fractured. The special histological architecture of the growth zones with their loosened fibrous lamellae might play a decisive role in the localisation of the lesions. The clinical importance of this type of injury and the radiological findings are discussed.

1. Twenty-two feet injured at the tarso-metatarsal level are reviewed.

2. Experiments with eleven cadaveric feet are reported.

3. The injuries are caused by forced plantar-flexion combined with rotation in most cases. Crushing of the foot alone often does not produce dislocation.

4. A classification is suggested.

5. The results of various treatments in this small series are presented. It is concluded that anatomical reduction is important, achieved if necessary by operation and internal fixation.

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. Attention is drawn to lesions of the inferior tibio-fibular ligaments. Two main types are described: the anterior type and the total type.

2. The clinical and radiological characteristics are described.

3. The value of strain-view radiography is stressed.

4. A plan of treatment is suggested.

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.

1 . Anterior dislocation of the head of the radius with or without fracture of the ulna is a forced pronation injury.

2. Full supination is essential for reduction, and immobilisation in full supination is the surest safeguard against recurrence of the deformity.

Two cases are described in which a traction lesion of the brachial plexus was complicated by sensory loss and anhidrosis in the second, third, and fourth cervical dermatomes. Both patients recovered spontaneously, though in one the recovery of muscle power in the limb was incomplete. It is believed that both were examples of a traction lesion of the cervical plexus. No similar case appears to have been recorded.

Twenty-two cases of paraplegia complicating injury of the cervical column have been reviewed. The vertebral injury may be due to flexion or hyperextension violence. Flexion injury—There are three types of flexion injury: 1) dislocation; 2) compression fracture of a vertebral body; 3) acute retropulsion of an intervertebral disc. Evidence is presented in support of the view that disc protrusion is the cause of the cord lesion when there is no radiographic evidence of bone injury, and in some cases at least when there is a compression fracture. Treatment is discussed and the indications for caliper traction and laminectomy are presented.

Hyperextension injurv—There are two types of hyperextension injury: 1) dislocation; 2) injury to arthritic spines. Hyperextension injury of an arthritic spine is the usual cause of paraplegia in patients over fifty years of age. The mechanism of hyperextension injury is described. The possible causes of spinal cord injury, and its treatment, are discussed.

1. Seventy-five patients sustained fractures of the pelvis with associated soft-tissue complications. Twenty died, and of these, thirteen died within forty-eight hours of admission to hospital.

2. The initial resuscitation and clinical assessment of these patients are discussed, and attention is drawn to the significance of the concomitant retroperitoneal haematoma as a cause of oligaemic shock, and as a dissembler of internal visceral injury.

3. The morphological fracture patterns are classified into six categories, but the fracture patterns are not correlated with specific visceral injuries.

4. Forty-six patients sustained urinary tract injuries. Of these, nineteen had suffered rupture of the urethra; fourteen had rupture of the bladder; two had both urethral and vesical disruption, and one patient had a torn ureter. The diagnosis and management of these injuries is discussed.

5. Twelve patients had a traumatic laceration or perforation of the ano-rectum. Nine of these patients had associated urethral or vesical injuries.

6. Four patients were involved in accidents and sustained pelvic fractures while in the last three months of pregnancy. The tragic outcome of this combination of circumstances is noted.

7. Attention is drawn to peripheral nerve injuries in association with pelvic fractures, and the difficulty of localising these lesions is stressed.

8. Eight instances of damage to the abdominal parietes are recorded. Four patients suffered skin and soft-tissue loss, two patients had diaphragmatic disruptions and two patients had abdominal wall dehiscences.

9. Major accident victims frequently have multiple injuries. This series of patients has been analysed to draw attention to the association of pelvic fractures with bizarre visceral injuries.

1. An account is given of twenty patients who had sustained accidental division of one or more foot tendons (other than tendo calcaneus).

2. Severe deformities occur when these injuries are neglected in children.

1. Three cases of traumatic thrombosis of the iliac arteries and one case of a false aneurysm of the internal iliac artery following closed injuries are described.

2. Results of the treatment of these cases are discussed.

Over a period of twenty years a small number of patients, thirty-one, have been seen who suffered injuries of the infraclavicular brachial plexus as a direct result of skeletal injury in the region of the shoulder joint.

Except for isolated circumflex nerve injuries the prognosis is generally good whatever part of the plexus is damaged. The treatment is conservative and its two most important features are prevention of stiffness of joints and the control, by regular galvanic stimulation, of denervation atrophy of muscle during the often prolonged period before recovery becomes apparent.

1. Evidence is presented that certain types of cervical spine injury are due mainly to lateral flexion forces.

2. These injuries are often complicated by a brachial plexus lesion as well as a lesion of the spinal cord.

3. It is not always easy to detect the brachial plexus injury when the patient is first seen.

4. In the cases reviewed there has been little or no recovery of cord function, and the existence of a brachial plexus injury has, of course, made rehabilitation much more difficult.

5. The practical importance of recognising the mechanism of this type of injury is that treatment which will cause further separation of the vertebrae is inadvisable.

1. Compression forces are mainly absorbed by the vertebral body. The nucleus pulposus, being liquid, is incompressible. The tense annulus bulges very little. On compression the vertebral end-plate bulges and blood is forced out of the cancellous bone of the vertebral body into the perivertebral sinuses. This appears to be the normal energy-dissipating mechanism on compression.

2. The normal disc is very resistant to compression. The nucleus pulposus does not alter in shape or position on compression or flexion. It plays no active part in producing a disc prolapse. On compression the vertebral body always breaks before the normal disc gives way. The vertebral end-plate bulges and then breaks, leading to a vertical fracture. If the nucleus pulposus has lost its turgor there is abnormal mobility between the vertebral bodies. On very gentle compression or flexion movement the annulus protrudes on the concave aspect–not on the convex side as has been supposed.

3. Disc prolapse consists primarily of annulus; it occurs only if the nucleus pulposus has lost its turgor. It then occurs very easily as the annulus now bulges like a flat tyre.

4. I have never succeeded in producing rupture of normal spinal ligaments by hyperextension or hyperflexion. Before rupture occurs the bone sustains a compression fracture. On the other hand horizontal shear, and particularly rotation forces, can easily cause ligamentous rupture and dislocation.

5. A combination of rotation and compression can produce almost every variety of spinal injury. In the cervical region subluxation with spontaneous reduction can be easily produced by rotation. If disc turgor is impaired this may occur with an intact anterior longitudinal ligament and explains those cases of tetraplegia without radiological changes or a torn anterior longitudinal ligament. The anterior longitudinal ligament can easily be ruptured by a rotation force and in my experience the so-called hyperextension and hyperflexion injuries are really rotation injuries.

6. Hyperflexion of the cervical spine or upper thoracic spine is an anatomical impossibility. In all spinal dislocations a body fracture may or may not occur with the dislocation, depending upon the degree of associated compression. In general, rotation forces produce dislocations, whereas compression forces produce fractures.

1 . A specific mechanism of injury can produce a tear of the articular disc of the wrist without any associated bony lesion.

2. Torn discs have been found associated with Colles's fractures and with dislocation of the inferior radio-ulnar joint.

3. The injury gives rise to clear-cut symptoms and definite physical signs.

4. Operation in fourteen cases has shown five types of tear of the disc.

5. Arthrographs of the wrist are helpful in establishing the diagnosis.

6. In isolated tears removal ofthe disc relieves the symptoms and does not prejudice function.

7. If there is other joint injury, removal of the disc cannot be expected to give as satisfactory a result.
