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.
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
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. Cite this article:
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.

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. Cite this article:
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. Cite this article:
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: 2. Treatment was guided by the following principles: 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.
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.
1. Twenty-seven patients with a Brown-SeÌquard syndrome resulting from trauma have been studied, fourteen of the left side of the cord and thirteen of the right. There were sixteen gunshot wounds and eleven closed injuries. 2. The prognosis for recovery is much better than the initial catastrophic nature of the symptoms and signs would indicate. 3. The pattern of recovery is discussed in detail and the long and rather tedious course of the treatment is indicated. 4. Spasticity on the side worse affected still presents a difficult problem, but a less severe one than that presented by flaccid paralysis.
1. The literature on paraplegia complicating hyperextension injuries of the cervical spine is reviewed, and the lack of any definite explanation of the mode of interference with cord function is noted. 2. A case is described in which a detailed dissection of the post-mortem specimen was carried out. On the basis of the findings it is suggested that one cause of the suppression of cord function in such injuries is thrombosis of the spinal arteries and liquefaction-necrosis of the cord.
1. Two cases of arterial damage complicating shoulder injuries are reported. 2. The treatment is described and the importance of early diagnosis is stressed. 3. Operation was indicated in both cases by developing ischaemia in spite of conservative measures.
We have assessed the efficacy of free nerve grafts in 90 cases of brachial plexus injury. Relatively good recovery of the elbow flexor and extensor muscles and of those of the shoulder girdle was found but recovery of the flexors and extensors of the forearm and of the intrinsic muscles of the hand was extremely poor. Poor results were found when spinal nerve roots seemed normal to the touch and appeared intact but had abnormal somatosensory evoked potentials or myelography. Recovery of the deltoid and infraspinatus muscles was better when injury had occurred to the circumflex and suprascapular nerves rather than to the plexus itself, perhaps because these nerves were explored in their entirety to determine the presence of multiple lesions. It is important to visualise the entire nerve thoroughly to assess the overall condition. Thorough exploration of the plexus and the use of intraoperative recording of somatosensory evoked potentials are essential.
Serious neck injury in rugby football is becoming more common, especially in schoolboys. We report five who presented with spinal cord damage between 1977 and 1983, two in the 1982-83 season. The mechanisms of injury, the treatment, and the outcome are discussed. We suggest measures to reduce the incidence of this most serious injury and draw attention to the appropriate management in the critical phase directly after injury.
1. Three new cases of injury to main arteries at orthopaedic operations are described, and a follow-up of two previously described cases is given. The rarity of these accidents is a credit to those engaged in orthopaedic surgery, for many orthopaedic operations are done very close to great vessels, and often under the bloodless conditions of a tourniquet. Nevertheless, it is well to have the risk of great vessel injury in mind because such an accident, although rare, may be a serious threat to life or limb. 2. It is important to repair the damaged artery rather than ligate it because the risk to the growth or viability of the limb is lessened. 3. The aim should be a return to full function with as near normal a vascular anatomy as possible.
1. A series of patients with recent ligamentous injuries of the ankle is presented. Stress radiography and arthrography were carried out in all cases, with surgical exploration where indicated. The findings are correlated. 2. Both stress radiography and arthrography are unreliable in the diagnosis of injuries to the "lateral ligament" of the ankle. 3. Arthrography may be useful in the demonstration of injury of the inferior tibio-fibular joint and of the medial ligament.
1. Three cases of delayed occlusion of the popliteal artery following trauma are described. 2. The lesion responsible is a partial rupture of the vessel with subsequent thrombosis. 3. All such lesions should be explored and preferably resected.
The use of the upright position of the patient, and a vertical incision for exposure of the brachial plexus, has been attended by no complications or serious hazards. The aid of skilled anaesthetists is acknowledged. The structures are visible and accessible; the operative field is steady; bleeding is controlled easily; and dissection is facilitated. By this technique it has been possible to explore a larger field from above, and division of the clavicle has seldom been necessary. Finally, and of importance, the operative area at shoulder level enables the surgeon to continue tedious dissection for some hours comfortably, and to escape postoperative postural complications in his own back.
1. Sixty-three traction injuries of the brachial plexus in adults are reviewed. Most of the patients were seen at regular intervals for more than three years after injury. 2. The mechanism of injury is described. Forcible separation of the head and shoulder is the essential factor, but the type of lesion is determined by the position of the upper limb at the time of the accident. 3. In traction injuries the main damage is intraneural, and the lesions are of considerable extent. Extraneural scarring is a conspicuous feature of old injuries, but it does not cause any damage to uninjured parts of the plexus. 4. The prognosis of each type of lesion of the plexus is discussed. Satisfactory recovery occurs in most lesions of the upper three roots. Degenerative lesions of the whole plexus never recover completely. Cases with Horner's syndrome always have severe residual paralysis. 5. Conservative treatment is advocated for traction injuries of the plexus and evidence is cited against early or late operations on the plexus. Reconstructive surgical procedures are sometimes indicated.
The operative treatment of lesions of the anterior cruciate ligament (ACL) in athletes has been widely advocated and performed. We have investigated the outcome of non-operative management in a lower-demand, general population. We reviewed a consecutive group of 228 patients, which excluded professional and high-level athletes, for two to 12 years after an ACL lesion had been diagnosed by arthroscopy. There was a low incidence of secondary ACL and meniscal surgery, 5.4% and 3.5% respectively, and all these procedures were performed during the first three years after the ACL injury. We studied a subgroup of 109 patients with follow-up of at least five years (mean 8.5 years) and evaluated them using the IKDC score. The general outcome was reasonably satisfactory, with 23% in grade A, 50% in grade B, 21% in grade C and only 6.4% in grade D. We found no statistically significant prognostic effect within this group as regards age, activity levels, or the incidence of associated lesions.
Four patients with injuries of the acetabular triradiate cartilage are presented. In three of them premature fusion of the cartilage occurred; two of these developed acetabular deformity and subluxation of the hip. In all patients the sacroiliac joint also was injured; in two, the joint was completely disrupted, leading to fusion and growth disturbance of the ilium. As injury of the triradiate cartilage is easily missed on the initial radiograph, it is advised that all patients with pelvic trauma should be followed clinically and radiographically for at least one year.
Two cases of laterally open knee joints with surrounding skin defects are reported. The joints were closed by muscle flaps fashioned from the lateral belly of the gastrocnemius, which was detached distally and folded upwards and forwards to cover the defect. The transposed muscle and the remainder of the wound were covered by free skin grafts. Results were satisfactory.
1. Four cases of vascular injury during lumbar disc removal are reported, and the literature is reviewed. One of the cases is unique in that the inferior mesenteric artery was transected. 2. Clinical syndromes associated with various vascular injuries are discussed. 3. The possibility ofvascular injury should always be kept in mind during lumbar lam inectomy for disc prolapse. Unexplained hypotension is strongly suggestive of a vascular catastrophe. The advent of high output cardiac failure in the patient who has recently undergone lumbar disc removal is almost diagnostic of traumatic arteriovenous fistula.
1. Sixty myelographs have been obtained in severe traction injuries of the brachial plexus. 2. Seventy-eight traumatic meningoceles were outlined. 3. Multiple meningoceles indicate a gloomy prognosis. 4. In forty patients the results were compared with those obtained with the "axon reflex." 5. Myelography is a valuable aid in obtaining an early prognosis but the results must be correlated with the clinical picture.
1. A series of six traction lesions of the common peroneal nerve in association with a severe adduction force to knee is described. 2. The reasons for failure of the nerve repair are discussed. 3. A new system of radiological marking of the anastomosis is described. 4. A less pessimistic view of the prognosis is taken than heretofore, and the management of the injury is discussed with a recommendation that a more conservative resection be done three months after the injury.
1 . Thirty-six patients with complete irrecoverable brachial plexus lesions have been studied. 2. Function has been compared after 1) arthrodesis of the shoulder with amputation through the arm, 2) so-called reconstructive procedures, and 3) no operative treatment. 3. The results of reconstructive operations have been so disappointing that we believe that this type of treatment should be abandoned. 4. Amputation-arthrodesis offers a better functional result than either reconstruction or no operation. Its value depends to a considerable extent on the manual dexterity of the patient. 5. A clerical worker who is not mechanically minded is less likely to use an artificial limb, and in this type of patient operation is perhaps best avoided.
1. A series of 149 consecutive cases of flexor tendon grafting in the fingers and thumb is reviewed and the results are analysed. A description of the technique which has evolved from this experience is given. 2. Replacement of a divided flexor digitorum profundus in the presence of an intact sublimis tendon restored a useful range of movement in 80 per cent of cases. 3. Replacement of both flexor digitorum profundus and sublimis gave good results in 70 to 80 per cent of cases. 4. Replacement of a divided flexor pollicis longus tendon gave good results in 85 per cent of cases. 5. The particular tendon used for the graft did not materially influence the result, but there are special indications for the use of the different tendons. 6. The choice of splintage or of early movement after operation does not appear to have a significant bearing upon the result. 7. The most important factor in determining the result is probably a precise and gentle surgical technique and complete haemostasis. Minor differences in method are of little importance. The failures in this series were due more to faulty performance of the operation than to any other single factor.
1. The mechanism of production of injury to the lateral condyle epiphysis is discussed. 2. A technique of closed reduction of rotational displacements of the epiphysis is described. Nine cases in which the method was successful are noted. 3. It is suggested that the injury should be classified with dislocation of the elbow.
We report the results in 33 patients who had nerve grafting of the axillary or the suprascapular nerve or of both. There were 32 men and one woman; their mean age was 21 years and the average interval between injury and operation was three months. At a mean follow-up of 27 months, the deltoid had recovered to M3 or better in 23 of 30 patients (77%) and the infraspinatus in 18 of 25 patients (72%). Shoulder elevation had reached 120° or more in 27 patients (82%), with external rotation of 30° or more in 27 (82%). Twenty-six patients (79%) could reach to the top of their head with their hand. Recovery of muscle strength, range of movement and shoulder function were satisfactory when surgery was performed within four months of the injury. Early exploration and nerve grafting can lead to a good functional recovery, but thorough exploration and careful repair of both nerves are essential.
1. Three cases of cement injection into the tissues of the thumb and index finger are recorded. 2. This is probably the first description of this type of injection injury. 3. Recommendations are made for the prevention of the injury.
1. Forty-two previously asymptomatic patients presenting with a recent rupture of the lateral ligament of the ankle, and twenty similar patients with a simple sprain of this ligament, have been followed for one year. The physical and radiological findings upon the completion of treatment have been related to functional instability of the foot one year later. 2. Persistent mechanical varus instability of the talus in the ankle mortise was a possible cause of functional instability one year after injury in four (or perhaps six) patients. 3. Adhesion formation was a possible cause of functional instability in one patient. 4. Seventeen patients finally displayed no clinical or radiological abnormality after injury, but noted functional instability of the foot one year later. 5. It is concluded that the pathological process which is usually responsible for functional instability of the foot after a lateral ligament injury is at present unknown.
1 . Power and precision grip (Napier 1956) were tested in 154 patients with nerve injuries. 2. The results are described, illustrated and discussed and it is suggested that these tests provide a simple, repeatable and objective method of assessing prehensile function of the hand as a whole.
1. Some of the problems of treatment of a patient with a head injury and a fractured femur are mentioned. 2. The methods of treatment and results obtained in fifty-nine such patients from the Oxford Accident Service are described.
1. Paralysis caused by anterior nerve root section, or by peripheral nerve section, leads to marked changes in the bones and muscles of the affected limb in experimental animals. Vascular changes are not the cause of the bone atrophy in a paralysed limb. 2. The altered properties of the bones of a paralysed limb are due almost entirely to a loss in the quantity of bone; bone quality is only slightly altered. 3. The bone changes that follow paralysis are due to the secondary loss of muscular activity. No evidence could be obtained that nerves exert any specific, trophic influence on bone.
After brachial plexus injuries, and other forms of paralysis of the upper limb, even when residual paralysis is very grave indeed, and even when the limb is almost flailâa forearm which can project forwards by the construction of a bone-block behind the elbow, with arthrodesis of the shoulder when necessary; a hand with fingers in the form of a claw and a thumb which opposes them; and a wrist which may perhaps be arthrodesed, but which still better can flex or extend when the forearm is pronated or supinated; together with the wise use of such muscles as are likely to gain function; may enable a patient to do very much more than he can with an artificial limb.
1) A case is reported of paraplegia with normal radiographic appearances in which cervical cord damage was shown at autopsy to have been due to hyperextension injury. 2) The mechanism of such injuries is discussed, together with the differential diagnosis from acute prolapse of an intervertebral disc. 3) The grave dangers of using the fully extended position of the cervical spine in the management of these cases is noted.
We studied 45 children who presented with an inversion injury of the ankle. The clinical signs suggested injury to the distal growth plate of the fibula, but the plain radiographs appeared normal. Ultrasound examination of the joint in 40 patients showed a subperiosteal haematoma consistent with a growth-plate injury in 23 (57.5%). Children who had been treated with a tubular bandage and crutches by random selection had a mean time to return of normal activity of 14.22 days compared with 21.60 days for those treated with a plaster-of-Paris cast (t = 3.60, p = 0.0032; d = 7.38, 95% CI 3.0 to 11.8). We conclude that children with inversion ankle injuries who have clinical signs of injury to the distal fibular growth plate but a normal radiological appearance, should be treated with a tubular bandage and crutches.
We report two cases of deformity of the ankle caused by physeal damage secondary to extravasation of an intravenous infusion in infancy. The possible mechanisms of injury to the physis are discussed.
1. The deep posterior muscles of the neck are innervated by the posterior branches of spinal nerves, which branch off immediately after the root emerges from the intervertebral foramen. Electromyographic examination of these muscles permits a differential diagnosis to be made between intraforaminal and extraforaminal brachial plexus lesions. 2. The earlier diagnosis and prognosis thus achieved permit definitive treatment, in particular suture of the torn nerve trunks in recent extraforaminal cases.
