Peripheral nerve injuries (PNI) occur in 10% of combat casualties. In the immediate field-hospital setting, an insensate limb can affect the surgeon's assessment of limb viability and in the long-term PNI remain a source of considerable morbidity. Therefore the aims of this study are to document the recovery of combat PNI, as well as report on the effect of current medical management in improving functional outcome. In this study, we present the largest series of combat related PNI in Coalition troops since World War II.

From May 2007 – May 2010, 100 consecutive patients (261 nerve injuries) were prospectively reviewed in a specialist PNI clinic. The functional recovery of each PNI was determined using the MRC grading classification (good, fair and poor). In addition, the incidence of neuropathic pain, the results of nerve grafting procedures, the return of plantar sensation, and the patients' current military occupational grading was recorded.

At mean follow up 26.7 months, 175(65%) of nerve injuries had a good recovery, 57(21%) had a fair recovery and 39(14%) had a poor functional recovery. Neuropathic pain was noted in 33 patients, with Causalgia present in 5 cases. In 27(83%) patients, pain was resolved by medication, neurolysis or nerve grafting. In 35 cases, nerve repair was attempted at median 6 days from injury. Of these 62%(22) gained a good or fair recovery with 37%(13) having a poor functional result. Forty-two patients (47 limbs) initially presented with an insensate foot. At final follow up (mean 25.4 months), 89%(42 limbs) had a return of protective plantar sensation. Overall, 9 patients were able to return to full military duty (P2), with 45 deemed unfit for military service (P0 or P8).

This study demonstrates that the majority of combat PNI will show some functional recovery. Adherence to the principles of war surgery to ensure that the wound is clear of infection and associated vascular and skeletal injuries are promptly treated will provide the optimal environment for nerve recovery. Although neuropathic pain affects a significant proportion of casualties, pharmacological and surgical intervention can alleviate the majority of symptoms. Finally, the presence of an insensate limb at initial surgery, should not be used as a marker of limb viability. The key to recovery of the PNI patient lies in a multi-disciplinary approach. Essential to this is regular surgical review to assess progress and to initiate prompt surgical intervention when needed. This approach allows early determination of prognosis, which is of huge value to the rehabilitating patient psychologically, and to the whole rehabilitation team.

Introduction

We present a series of patients who have had secondary reconstruction of war injuries to the upper and lower limbs, sustained during the Iraq and Afghanistan conflicts.

Material and Methods

All patients were seen at the combined Peripheral Nerve Injuries Clinic at the Defence Medical Centre for Rehabilitation, Headley Court. All surgery was performed at Odstock Hospital. Procedures include scar excision and neurolysis (all patients), release of scar contractures, tenolysis, tendon transfers, revision nerve grafts, excision of neuroma, and soft tissue reconstruction using pedicled or free flaps.

The outcomes of 261 nerve injuries in 100 patients were graded good in 173 cases (66%), fair in 70 (26.8%) and poor in 18 (6.9%) at the final review (median 28.4 months (1.3 to 64.2)). The initial grades for the 42 sutures and graft were 11 good, 14 fair and 17 poor. After subsequent revision repairs in seven, neurolyses in 11 and free vascularised fasciocutaneous flaps in 11, the final grades were 15 good, 18 fair and nine poor. Pain was relieved in 30 of 36 patients by nerve repair, revision of repair or neurolysis, and flaps when indicated. The difference in outcome between penetrating missile wounds and those caused by explosions was not statistically significant; in the latter group the onset of recovery from focal conduction block was delayed (mean 4.7 months (2.5 to 10.2) vs 3.8 months (0.6 to 6); p = 0.0001). A total of 42 patients (47 lower limbs) presented with an insensate foot. By final review (mean 27.4 months (20 to 36)) plantar sensation was good in 26 limbs (55%), fair in 16 (34%) and poor in five (11%). Nine patients returned to full military duties, 18 to restricted duties, 30 to sedentary work, and 43 were discharged from military service. Effective rehabilitation must be early, integrated and vigorous. The responsible surgeons must be firmly embedded in the process, at times exerting leadership.

We describe 261 peripheral nerve injuries sustained in war by 100 consecutive service men and women injured in Iraq and Afghanistan. Their mean age was 26.5 years (18.1 to 42.6), the median interval between injury and first review was 4.2 months (mean 8.4 months (0.36 to 48.49)) and median follow-up was 28.4 months (mean 20.5 months (1.3 to 64.2)). The nerve lesions were predominantly focal prolonged conduction block/neurapraxia in 116 (45%), axonotmesis in 92 (35%) and neurotmesis in 53 (20%) and were evenly distributed between the upper and the lower limbs. Explosions accounted for 164 (63%): 213 (82%) nerve injuries were associated with open wounds. Two or more main nerves were injured in 70 patients. The ulnar, common peroneal and tibial nerves were most commonly injured. In 69 patients there was a vascular injury, fracture, or both at the level of the nerve lesion. Major tissue loss was present in 50 patients: amputation of at least one limb was needed in 18. A total of 36 patients continued in severe neuropathic pain.

This paper outlines the methods used in the assessment of these injuries and provides information about the depth and distribution of the nerve lesions, their associated injuries and neuropathic pain syndromes.

A schwannoma is a benign nerve sheath tumour originating from schwann cells. It is the most commonly occurring peripheral nerve sheath tumour. The common sites of occurrence are the head and neck followed by the upper and lower limbs. Diagnosis is straightforward and is made clinically. Schwannomas of the tibial nerve pose a problem. The literature describes them as causes of chronic, intractable lower limb pain because their diagnosis is often delayed for several years. The main reason postulated is that a lump is not always palpable in the early phases and hence chronic cramping pain in the calf or foot is attributed to lumbosacral radiculopathy or local neuropathy.

We report the largest case series of twenty-five patients diagnosed with a tibial nerve schwannoma. Only three cases were diagnosed within a year of initial presentation. The mean time to diagnosis was eighty-six months. The most common site of pain was the sole of the foot (eighteen cases). A Tinel's sign was elicited in nineteen cases. MRI confirmed the diagnosis in all the twenty cases where it was performed. Surgical resection was performed in all cases yielding excellent results. Only one patient required further neurolysis for persisting pain.

In patients with a long history of neuropathic lower limb pain, where lumbar and pelvic lesions have been excluded, a high index of suspicion should be maintained for a peripheral nerve tumour. Delay in diagnosis is commonly due to lack of familiarity with peripheral nerve pathology and the absence of a palpable lump. The delay can result in numerous unnecessary medical and surgical interventions in this group of distressed patients. The Tinel's sign is the key to identifying a tumour of neural origin in the absence of a palpable lump. Surgical resection of the tumour remains safe and effective in providing symptomatic relief.

Objective: This study was performed to review the current treatment and outcome of extra abdominal fibromatosis in our hospital, supplemented by a current review of the literature.

Method: A retrospective study of 72 patients with fibromatosis seen at the Royal National Orthopaedic Hospital (RNOH) between 1980 and 2009 was performed. Patients were identified using the databases at the peripheral nerves injury (PNI) unit and the histopathology department. Medical and radiological records were reviewed.

Results: There were 72 patients treated at the Sarcoma and PNI units. 40 patients were primary referrals, and 32 more had operations at the referring hospital. An operation was not carried out in 5 patients. 48 patients were treated by operation alone and this was supplemented by adjuvant therapy in 19 patients. Recurrence was seen in 24 (50.0%) of the operation alone group and 10 (52.6%) in the operation and adjuvant therapy group. The rate of recurrence was lower with complete excision. However, complete excision was impossible in some cases because of extension into the chest or spinal canal, or involvement with the axial vessels and lumbosacral or brachial plexus.

Conclusion: We suggest that operative excision should seek to preserve function and that supplementary adjuvant therapy may reduce the risk of recurrence, although excision margin appears to be the most important factor. The aggressive, infiltrative behaviour of deep fibromatoses and the associated genetic mutations identified, clearly distinguish them from the superficial fibromatoses and makes their treatment more difficult and dangerous, especially where vital structures are involved. We agree with the recent recommendation that these lesions should be treated in regional soft tissue sarcoma units.

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.

Over 75% of combat casualties from Iraq and Afghanistan sustain injuries to the extremities, with 70% resulting from the effects of explosions. Damage to peripheral nerves may influence the surgical decision on limb viability in the short-term, as well as result in significant long-term disability. To date, there have been no reports of the incidence and severity of nerve injury in the current conflicts.

A prospective assessment of United Kingdom (UK) Service Personnel attending a specialist nerve injury clinic was performed. For each patient the mechanism, level and severity of injury to the nerve was assessed and associated injuries were recorded.

Fifty-six patients with 117 nerve injuries (median 2, range 1–5) were eligible for inclusion. This represents 12.9% of casualties sustaining an extremity injury. The most commonly injured nerves were the tibial (19%), common peroneal (16%) and ulnar nerves (16%). 25% (29) of nerve injuries were conduction block, 41% (48) axonotmesis and 34% (40) neurotmesis. The mechanism of injury did not affect the severity of injury sustained (explosion vs gunshot wound (GSW), p=0.53). An associated fracture was found in only 48% of nerve injuries and a vascular injury in 35%. The presence of an associated vascular injury resulted in more severe injuries (conduction vs axonotmesis and neurotmesis, p< 0.05). Nerves injured in association with a fracture, were more likely to develop axonotmesis (p< 0.05).

The incidence of peripheral nerve injury from combat wounds is higher than previously reported. This may be related to increasing numbers of casualties surviving with complex extremity wounds. In a polytrauma situation, it may be difficult to assess a discrete peripheral neurological lesion. As only 35% of nerves injured are likely to have anatomical disruption, the presence of an intact nerve at initial surgery should not preclude the possibility of an injury. Therefore, serial examinations combined with appropriate neurophysiologic examination in the post-injury period are necessary to aid diagnosis and to allow timely surgical intervention. In addition, conduction block nerve injuries can be expected to make a full recovery. As this accounts for 25% of all nerve injuries, we recommend that the presence of an insensate extremity should not be used as an indicator for assessing limb viability.

Introduction: Shoulder relocation is commonly performed for the subluxating or dislocated shoulder secondary to Obstetric Brachial Plexus Palsy (OBPP). We have observed that even when relocation is performed at a young age, remodelling of the immature, dysplastic glenoid is often unreliable, resulting in recurrent incongruity and requiring treatment of the glenoid dysplasia.

Methods and results: In a series of 19 patients, we used a posterior bone block to buttress the deficient glenoid at the time of shoulder relocation. At a mean follow up of 28 months (6–73 months), we describe failure in at least 50% with erosion of the bone block, progressive subluxation and resultant pain.

A different technique of glenoplasty is now used. An osteotomy of the glenoid is performed postero-inferiorly, elevating the glenoid forward to decrease its volume. Bone graft, often taken from an enlarged and resected coracoid is then packed into the osteotomy and the whole assembly is held with a plate. In a series of 11 patients with a mean age of 6.7 years (1–18 years) we describe good results at short term followup, suggesting that this is a technique warranting further investigation.

Conclusion: We believe that where a deficient glenoid is found at surgery for relocation of the shoulder in OBPP, a glenoplasty should be performed at the same time whatever the age of the patient, as glenoid remodelling will not reliably occur. We no longer advocate posterior bone block in these cases as it has a significant failure rate.

Purpose: To investigate the mode of presentation, management and outcome of ischaemic contracture following a supracondylar fracture with a pink, pulseless hand.

Methods: We reviewed the database at our tertiary referral unit to identify cases over a 20 year period who had been referred for complications of a supracondylar fracture and/or a Volkmann’s ischaemic contracture.

Results: We identified 20 children with Volkmann’s ischaemic contracture following a supracondylar fracture. Of these, 4 patients (mean age 5, range 2–11) were referred to us with evidence of an ischaemic contracture but they had always had a pink albeit pulseless hand. Two of these 4 had undergone vascular exploration at 48 hours and at 72 hours but despite this developed an ischaemic contracture.

The 2 patients with the most severe contractures have undergone surgical intervention for their contracture, and 2 were managed conservatively with splinting. All 4 cases have residual problems with hand function (mean follow-up 5.5 years, range 2–11).

Conclusions: Volkmann’s ischaemic contracture should be a preventable condition. The pink albeit pulseless hand is at increased risk of ischaemic muscle and nerve damage and should not be ignored as the consequences are potentially devastating.

Significance: Clinicians must consider whether they feel that their management protocols for the pink, pulseless hand are robust and defensible.

A series of 26 children was referred to our specialist unit with a ‘pink pulseless hand’ following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedures were recorded. The mean age at presentation was 8.6 years (2 to 12). There were eight girls and 18 boys.

Only four of the 26 patients had undergone immediate surgical exploration before referral and three of these four had a satisfactory outcome. In one child the brachial artery had been explored unsuccessfully at 48 hours. As a result 23 of the 26 children presented with established ischaemic contracture of the forearm and hand. Two responded to conservative stretching. In the remaining 21 the antecubital fossa was explored. The aim of surgery was to try to improve the function of the hand and forearm, to assess nerve, vessel and muscle damage, to relieve entrapment and to minimise future disturbance of growth.

Based on our results we recommend urgent exploration of the vessels and nerves in a child with a ‘pink pulseless hand’, not relieved by reduction of a supracondylar fracture of the distal humerus and presenting with persistent and increasing pain suggestive of a deepening nerve lesion and critical ischaemia.

To review the outcome of compound injury to the shoulder in which traumatic anterior dislocation is associated with concomitant rotator cuff tear and injury to the brachial plexus.

22 patients initially treated at the Peripheral Nerve Injury Unit since 1994 were reviewed from notes, telephone and clinically (n=13) where possible. 19 men and 3 women of average age 53 years were treated with a minimum 3-year follow up. All patients underwent exploration of the brachial plexus and nerve repair where required (graft n=5). Patients had either proven large cuff tear (n=13) or avulsion fracture of greater tuberosity with cuff injury (n=9). 7 of 13 cuff injuries and 7 of 9 tuberosity fractures had been repaired. Nerve injury at exploration was to circumflex (n=20), supra-scapular (n=12), musculocutaneous (n=6), or at the cord level (Posterior n=10, Lateral n=7 Medial n=8). Outcome measures were Berman pain score, sensation, muscle power (MRC grade), abduction, functional scores (Mallett and DASH) and return to work. Statistical analysis used tests for non-parametric data.

22 patients had exploration of the plexus. Most patients did not have an isolated nerve lesion (n=4). Increased depth of nerve lesion correlated with poorer functional outcome. E.g. for circumflex nerve injury (n=18), conduction block (n=8) vs. axonotmesis or neurotmesis (n =10) functional range of movement as assessed by Mallett score was significantly different; Mann Whitney U test p=0.043. Late exploration of nerve tended to correlate with poor outcome, as did late repair of rotator cuff, but not to statistical significance.

Our explorations have shown the nerve injury sustained in these patients to be more widespread than expected. We believe early exploration is vital to give an accurate diagnosis and predict outcome for the nerve lesion. This is particularly important in the presence of associated cuff injury where early repair confers favourable outcome.

We reviewed 234 benign solitary schwannomas treated between 1984 and 2004. The mean age of the patients was 45.2 years (11 to 82). There were 170 tumours (73%) in the upper limb, of which 94 (40%) arose from the brachial plexus or other nerves within the posterior triangle of the neck. Six (2.6%) were located within muscle or bone. Four patients (1.7%) presented with tetraparesis due to an intraspinal extension.

There were 198 primary referrals (19 of whom had a needle biopsy in the referring unit) and in these patients the tumour was excised. After having surgery or an open biopsy at another hospital, a further 36 patients were seen because of increased neurological deficit, pain or incomplete excision. In these, a nerve repair was performed in 18 and treatment for pain or paralysis was offered to another 14.

A tender mass was found in 194 (98%) of the primary referrals. A Tinel-like sign was recorded in 155 (81%). Persistent spontaneous pain occurred in 60 (31%) of the 194 with tender mass, impairment of cutaneous sensibility in 39 (20%), and muscle weakness in 24 (12%).

After apparently adequate excision, two tumours recurred. No case of malignant transformation was seen.

We report a case of iatrogenic sciatic nerve injury caused by pre-operative intraneural injection of local anaesthetic at total hip replacement. To our knowledge, this is unreported in the orthopaedic literature. We consider sacral nerve blockade in patients undergoing total hip replacement to be undesirable and present guidelines for the management of peri-operative sciatic nerve injury.

We investigated the effect of delay before nerve repair on neuropathic pain after injury to the brachial plexus. We studied 148 patients, 85 prospectively and 63 retrospectively. The mean number of avulsed spinal nerves was 3.2 (1 to 5). Pain was measured by a linear visual analogue scale and by the peripheral nerve injury scale. Early repair was more effective than delayed repair in the relief from pain and there was a strong correlation between functional recovery and relief from pain.

Purpose: The relationship of pattern of injury to this region of the knee to the intraoperative finding of abnormal common peroneal nerve position and associated nerve palsy was studied.

Methods: 54 consecutive patients with posterolateral corner disruption requiring surgery were assessed prospectively by MRI, arthroscopic examination, and by operative display. The pattern of disruption, the status of the biceps tendon and any displacement of the common peroneal nerve were recorded.

Results: Of the 54 cases, there were 9 with CPN palsy, 18 were seen to have distal injuries (13 suffering a fibular head avulsion fracture and 5 biceps tendon avulsion with no fracture). There was a strong relationship (p< 0.001) between such distal posterolateral corner injury and abnormal position of the common peroneal nerve, as 16 of the 18 (90%) patients were seen to have abnormal nerve position. No proximal injury resulted in abnormal nerve position and only 1 was associated with CPN palsy. 7 of the 13 cases of fibular head fracture had CPN palsy, and 1 of the 5 distal soft tissue avulsions.

Conclusion: There is a strong association of distal soft tissue avulsion and fibular head fracture and CPN palsy in these injuries. Whenever such a distal injury is suspected, the surgeon operating in this region should expect an abnormal position of the common peroneal nerve and appreciate the increased risk of iatrogenic damage. Presumably since the CPN is intimately bound to the biceps tendon by deep fascia, proximal retraction of the biceps tendon results in displacement of the CPN to an abnormal position and accounts for the high incidence of nerve palsy.

Objective: The reported incidences of traumatic and iatropathic nerve injuries with supracondylar fractures in children are 12–16% and 6% respectively, with the majority recovering spontaneously. We performed a retrospective review of lesions referred to our tertiary unit to determine the incidence of surgical intervention.

Methods: Between 1997 and 2002, 37 neuropathies (associated with 32 supracondylar fractures) in 19 males and 13 females with an average age of 7.9 years were referred for further management. 8 fractures were classified as Gartland grade 2 and 24 as grade 3. All fractures were closed, with 2 treated non-operatively, 20 by closed reduction and percutaneous pinning and 10 by open reduction and internal fixation at the referring hospitals.

Results: The ulnar nerve was the most frequently injured (51.4%), followed by median (27%) and radial (21.6%) nerve palsies. 14 (37.8%) neuropathies were related to the fracture, while 23 (62.2%) were iatropathic. 10 patients (31.3%) required operative exploration while 3 (9.4%) were listed for surgery but were cancelled as they were recovering. Nerve grafting was used in 4 of the 10 operated cases, the donor nerve being the medial cutaneous nerve of the forearm in 3 and the superficial radial nerve in one. 26 patients (81.3%) had excellent outcomes, 5 (15.6%) good and 1 (3.1%) fair.

Conclusion: Although most had excellent outcomes, surgical exploration was required for nearly a third of the cases referred to our unit. This is in contrast to the current literature, which suggests that the majority of supracondylar neuropathies recover spontaneously.

We describe the results of surgical treatment in a prospective study of 183 consecutive cases of subluxation (101) and dislocation (82) of the shoulder secondary to obstetric brachial plexus palsy between 1995 and 2000. Neurological recovery was rated ‘good’ or ‘useful’ in all children, whose lesions fell into groups 1, 2 or 3 of the Narakas classification. The mean age at operation was 47 months (3 to 204). The mean follow-up was 40 months (24 to 124).

The mean gain in function was 3.6 levels (9.4 to 13) using the Mallet score and 2 (2.1 to 4.1) on the Gilbert score. The mean active global range of shoulder movement was increased by 73°; the mean range of active lateral rotation by 58° and that of supination of the forearm by 51°. Active medial rotation was decreased by a mean of 10°. There were 20 failures. The functional outcome is related to the severity of the neurological lesion, the duration of the dislocation and onset of deformity.
