We describe a management strategy for upper- and lower-limb fractures with associated arterial injury and report the results in 113 cases treated over a period of 18 years. Primary amputation was performed in 23 patients and of those who underwent primary vascular repair, 27 needed secondary amputation, two-thirds of them within a week of the injury. Of those requiring secondary amputation, 51.8% had ischaemia exceeding six hours, 81.4% had severe soft-tissue injury and 85.2% had type III open fractures. The patients whose limbs had been salvaged were followed up for an average of 5.6 years. The eventual outcome depended on the severity of the fracture, the degree of soft-tissue damage, the length of the ischaemic period, the severity of neurological involvement, and the presence of associated major injuries. There was a 30% incidence of long-term disability in the salvaged limbs, largely due to poor recovery of neurological function. Prompt recognition of such combined injuries is vital and requires a high index of suspicion in patients with multiple injuries and with certain fracture patterns. We recommend a multidisciplinary approach, liberal use of pre-operative angiography in upper-limb injuries and selective use of intra-operative angiography in lower-limb injuries. Stable external or internal fixation of the fractures and re-establishment of limb perfusion are urgent surgical priorities to reduce the period of ischaemia which is critical for successful limb salvage

Hand function was evaluated in 105 patients who had been operated on in early infancy for brachial plexus birth palsy. The mean follow-up after surgery was for 13.4 years (5.0 to 31.5). Fine sensation, stereognosis, grip and pinch strength and the Raimondi scale were recorded. Fine sensation was normal in 34 of 49 patients (69%) with C5–6 injury, 15 of 31 (48%) with C5–7 and in 8 of 25 (32%) with total injury. Loss of protective sensation or absent sensation was noted in some palmar areas of the hand in 12 of 105 patients (11%). Normal stereognosis was recorded in 88 of the 105 patients (84%), whereas only 9 of the 105 (9%) had normal grip strength. The mean Raimondi scale scores were 4.57 (3 to 5) (C5–6), 4.26 (1 to 5) (C5–7) and 2.16 (0 to 5) in patients with total injury. The location of impaired sensation was related to the distribution of the root injury. Avulsion type of injury correlated with poor recovery of hand function

Seat-belt fractures of the lumbar spine in adolescents and adults are well recognised but there are few reports of these injuries in young children. We reviewed all seat-belt injuries in skeletally immature patients (Risser 0), seen at a tertiary referral centre between 1974 and 1991. There were ten cases, eight girls and two boys, with an average age of 7.5 years (3 to 13). Four distinct patterns of injury were observed, most commonly at the L2 to L4 level. Paraplegia, which is thought to be uncommon, occurred in three of our ten cases. Four children had intra-abdominal injuries requiring laparotomy. There was a delay in diagnosis either of the spinal or of the intra-abdominal injury in five cases, although all had contusion of the abdominal wall, the 'seat-belt sign'. Treatment of the fractures was conservative, by bed rest and then hyperextension casts. The incidence of this potentially devastating injury can be reduced by the optimal use of restraints, but there is often a delay in diagnosis. Our classification system may aid in the early detection and evaluation of this injury

This review discusses the causes, outcome and prevention of whiplash injury, which costs the economy of the United Kingdom approximately £3.64 billion per annum. Most cases occur as the result of rear-end vehicle collisions at speeds of less than 14 mph. Patients present with neck pain and stiffness, occipital headache, thoracolumbar back pain and upper-limb pain and paraesthesia. Over 66% make a full recovery and 2% are permanently disabled. The outcome can be predicted in 70% after three months

1. Injuries of the sternum from flexion-compression violence are described and contrasted with injuries from direct violence. The characteristic feature of flexion-compression injuries is a dislocation or fracture at or near the manubrio-sternal joint with backward displacement of the manubrium. 2. Treatment is outlined, with special reference to the indications for open reduction and wire fixation. 3. The mechanism of flexion-compression injuries of the sternum is discussed. The opinion is expressed that most of the force is transmitted to the sternum by the ribs—especially the upper ribs

Crushing of the radial side of the hand results in a wide spectrum of injuries varying from contusion of muscles to total loss. The main problem concerns the function of the thumb. The results of such injuries in 161 hands were reviewed. Those with mild injuries treated conservatively or by debridement alone had good results. When skin flaps were required for wound coverage, the results were still satisfactory. However, when bones and joints were injured, the results were poor. In certain patients opponensplasty through scarred tissue proved to be a good procedure to improve the function of the thumb

We describe 20 patients, aged between 43 and 88 years, with delayed nerve palsy or deepening of an initial palsy caused by arterial injury from low-energy injuries to the shoulder. The onset of palsy ranged from immediately after the injury to four months later. There was progression in all the patients with an initial partial nerve palsy. Pain was severe in 18 patients, in 16 of whom it presented as neurostenalgia and in two as causalgia. Dislocation of the shoulder or fracture of the proximal humerus occurred in 16 patients. There was soft-tissue crushing in two and prolonged unconsciousness from alcoholic intoxication in another two. Decompression of the plexus and repair of the arterial injury brought swift relief from pain in all the patients. Nerve recovery was generally good, but less so in neglected cases. The interval from injury to the repair of the vessels ranged from immediately afterwards to 120 days. Delayed onset of nerve palsy or deepening of a nerve lesion is caused by bleeding and/or impending critical ischaemia and is an overwhelming indication for urgent surgery. There is almost always severe neuropathic pain

This paper describes seven patients who developed late vertebral deformity after flexion injuries of the cervical spine. In four the clinical and radiological features were subtle and because the patients walked into an emergency department the severity of the injury was not initially appreciated. Certain specific clinical and radiological features of flexion injury are described and emphasis is placed on the importance of correct management. A radiological tetrad is described which should alert the surgeon to the possibility of damage to the posterior interspinous complex of the cervical spine and so lead to further radiological investigations. Despite the frequency of flexion injuries the alarming complications described in this paper are rare

We studied 50 consecutive patients presenting at an accident department after rear-end vehicle collisions and recorded symptoms and psychological test scores within one week of injury, at three months and at two years. The range of neck movement was noted at three months. Within one week of injury, psychological test scores were normal in 82% of the group but became abnormal in 81% of the patients with intrusive or disabling symptoms at over three months (p < 0.001) and remained abnormal in 69% at two years. The clinical outcome after two years could be predicted at three months with 76% accuracy by neck stiffness, 74% by psychological score and 82% by a combination of these variables. The severity of symptoms after a whiplash injury is related both to the physical restriction of neck movement and to psychological disorder. The latter becomes established within three months of the injury

We studied a consecutive series of 58 patients with penetrating missile injuries of the brachial plexus to establish the indications for exploration and review the results of operation. At a mean of 17 weeks after the initial injury, 51 patients were operated on for known or suspected vascular injury (16), severe persistent pain (35) or complete loss of function in the distribution of one or more elements of the brachial plexus (51). Repair of the nerve and vascular lesions abolished, or significantly relieved, severe pain in 33 patients (94%). Of the 36 patients who underwent nerve graft of one or more elements of the plexus, good or useful results were obtained in 26 (72%). Poor results were observed after repairs of the medial cord and ulnar nerve, and in patients with associated injury of the spinal cord. Neurolysis of lesions in continuity produced good or useful results in 21 of 23 patients (91%). We consider that a vigorous approach is justified in the treatment of penetrating missile injury of the brachial plexus. Primary intervention is mandatory when there is evidence of a vascular lesion. Worthwhile results can be achieved with early secondary intervention in patients with debilitating pain, failure to progress and progression of the lesion while under observation. There is cause for optimism in nerve repair, particularly of the roots C5, C6 and C7 and of the lateral and posterior cords, but the prognosis for complete lesions of the plexus associated with damage to the cervical spinal cord is particularly poor

We report a case of osteonecrosis of the femoral head in a young man who is a carrier of the prothrombin gene mutation. We suggest that an electrical injury to his lower limb may have triggered intravascular thrombosis as a result of this mutation with subsequent osteonecrosis of the femoral head. No case of osteonecrosis of the femoral head secondary to a distant electrical injury has previously been reported

A prospective study of 33 civilian parachutists with 41 injuries is presented. Because the training for civilians is less rigorous than that for military parachutists, the hospital admission rate for severe injuries was high (81.8%). Most injuries occurred during landing and the ankle was most frequently involved. The types and possible mechanisms of injury are discussed, as well as recommendations for modifying the civilian training programme

The late results of tarsometatarsal injuries in 33 patients have been reviewed. The average follow-up period was 15 years (range 11 to 20 years). Methods of treatment included cast immobilisation, and closed or open reduction with or without internal fixation. All patients noted diminishing symptoms after injury and all but six returned to their former occupation. Neither the initial fracture type nor the treatment had any apparent bearing on subsequent function; nor was there any correlation between radiographic assessment of the injury and the patient's symptoms

Many authors recommend surgery to remove retropulsed bone fragments from the canal in burst fractures to 'decompress' the spinal canal. We believe, however, that neurological damage occurs at the moment of injury when the anatomy is most distorted, and is not due to impingement in the resting positions observed afterwards. We studied 20 consecutive patients admitted to our spinal injuries unit over a two-year period with a T12 or L1 burst fracture. There was no correlation between bony or canal disruption and the degree of neurological compromise sustained but there was a significant correlation between the energy of the injury (as gauged by the Injury Severity Score) and the neurological status (p < 0.001). This suggests that neurological injury occurs at the time of trauma rather than being a result of pressure from fragments in the canal afterwards and questions the need to operate simply to remove these fragments

Antegrade intramedullary nailing of fractures of the shaft of the humerus is reported to cause impairment of the shoulder joint. We have reviewed 33 patients with such fractures to assess how many had injuries to the ipsilateral shoulder. All had an MR scan of the shoulder within 11 days of injury. The unaffected shoulder was also scanned as a control. There was evidence of abnormality in 21 of the shoulders (63.6%) on the injured side; ten had bursitis of the subacromial space, five evidence of a partial tear of the rotator cuff, one a complete rupture of the supraspinatus tendon, four inflammatory changes in the acromioclavicular joint and one a fracture of the coracoid process. These injuries may contribute to pain and dysfunction of the shoulder following treatment, and their presence indicates that antegrade nailing is only partly, if at all, responsible for these symptoms

We reviewed 110 patients with an unstable fracture of the pelvic ring who had been treated with a trapezoidal external fixator after a mean follow-up of 4.1 years. There were eight open-book (type B1, B3-1) injuries, 62 lateral compression (type B2, B3-2) and 40 rotationally and vertically unstable (type C1-C3) injuries. The rate of complications was high with loss of reduction in 57%, malunion in 58%, nonunion in 5%, infection at the pin site in 24%, loosening of the pins in 2%, injury to the lateral femoral cutaneous nerve in 2%, and pressure sores in 3%. The external fixator failed to give and maintain a proper reduction in six of the eight open-book injuries, in 20 of the 62 lateral compression injuries, and in 38 of the 40 type-C injuries. Poor functional results were usually associated with failure of reduction and an unsatisfactory radiological appearance. In type-C injuries more than 10 mm of residual vertical displacement of the injury to the posterior pelvic ring was significantly related to poor outcome. In 14 patients in this unsatisfactory group poor functional results were also affected by associated nerve injuries. In lateral compression injuries the degree of displacement of fractures of the pubic rami caused by internal rotation of the hemipelvis was an important prognostic factor. External fixation may be useful in the acute phase of resuscitation but it is of limited value in the definitive treatment of an unstable type-C injury and in type-B open-book injuries. It is usually unnecessary in minimally displaced lateral compression injuries

Injuries to the spinal cord may be associated with increased healing of fractures. This can be of benefit, but excessive bone growth can also cause considerable adverse effects. We evaluated two groups of patients with fractures of the spinal column, those with neurological compromise (n = 10) and those without (n = 15), and also a control group with an isolated fracture of a long bone (n = 12). The level of transforming growth factor-beta (TGF-β), was measured at five time points after injury (days 1, 5, 10, 42 and 84). The peak level of 142.79 ng/ml was found at day 84 in the neurology group (p < 0.001 vs other time points). The other groups peaked at day 42 and had a decrease at day 84 after injury (p ≤ 0.001). Our findings suggest that TGF-β may have a role in the increased bone turnover and attendant complications seen in patients with acute injuries to the spinal cord

Forty-six children with Monteggia fracture-dislocations have been studied. The circumstances of the accident could rarely be recalled so that the mechanism of injury remains unclear. The study did, however, confirm the importance of conservative management of the injury in children; unlike the adult variety, this gave very satisfactory results. Our review also supports the classification into three basic types of Monteggia lesion according to the direction of displacement of the dislocated radial head. For simplicity, all other types, variations or equivalents can be regarded as belonging to these basic patterns; in particular we include those controversial cases in which the radiohumeral dislocation is combined with a fractured olecranon

Peripheral nerve injury is an uncommon but serious complication of hip surgery that can adversely affect the outcome. Several studies have described the use of electromyography and intra-operative sensory evoked potentials for early warning of nerve injury. We assessed the results of multimodal intra-operative monitoring during complex hip surgery. We retrospectively analysed data collected between 2001 and 2010 from 69 patients who underwent complex hip surgery by a single surgeon using multimodal intra-operative monitoring from a total pool of 7894 patients who underwent hip surgery during this period. In 24 (35%) procedures the surgeon was alerted to a possible lesion to the sciatic and/or femoral nerve. Alerts were observed most frequently during peri-acetabular osteotomy. The surgeon adapted his approach based on interpretation of the neurophysiological changes. From 69 monitored surgical procedures, there was only one true positive case of post-operative nerve injury. There were no false positives or false negatives, and the remaining 68 cases were all true negative. The sensitivity for predicting post-operative nerve injury was 100% and the specificity 100%. We conclude that it is possible and appropriate to use this method during complex hip surgery and it is effective for alerting the surgeon to the possibility of nerve injury

Locognosia, the ability to localise touch, is one aspect of tactile spatial discrimination which relies on the integrity of peripheral end-organs as well as the somatosensory representation of the surface of the body in the brain. The test presented here is a standardised assessment which uses a protocol for testing locognosia in the zones of the hand supplied by the median and/or ulnar nerves. The test-retest reliability and discriminant validity were investigated in 39 patients with injuries to the median or ulnar nerve. Intraclass correlation coefficients were used to calculate the test-retest reliability. Discriminant validity was assessed by comparing the injured with the unaffected hand. Excellent test-retest reliability was demonstrated for the injuries to the median (intraclass correlation coefficient 0.924, 95% confidence interval 0.848 to 1.00) and the ulnar nerves (intraclass correlation coefficient 0.859, 95% confidence interval 0.693 to 1.00). The magnitude of the difference in scores between affected and unaffected hands showed good discriminant validity. For injuries to the median nerve the mean difference was 11.1 points (1 to 33; . sd. 7.4), which was statistically significant (p < 0.0001, paired t-test) and for those of the ulnar nerve it was 4.75 points (1 to 13.5; . sd. 3.16), which was also statistically significant (paired t-test, p < 0.0001). The locognosia test has excellent test-retest reliability, is a valid test of tactile spatial discrimination and should be included in the evaluation of outcome after injury to peripheral nerves
