Subtalar arthrodesis using interposition iliac crest bone graft after calcaneal fracture.

Fifteen consecutive patients with hindfoot pain after calcaneal fracture underwent subtalar arthrodesis using interposition iliac crest bone graft. Outcome and correction of calcaneal collapse were assessed before and after surgery with clinical examination, visual analogue scores, and standard x-rays while weightbearing. Eleven of the 15 patients were satisfied with the procedure. There were four failures due to transverse tarsal joint arthritis, overcorrection, and reflex sympathetic dystrophy. Radiographic examination revealed restoration of heel height, with 100% union rate of the arthrodesis. The described technique allows arthrodesis and correction of calcaneal collapse after calcaneal fracture.

Chronic ankle pain caused by osteoid osteoma of the neck of the talus.

Five patients with osteoid osteomas of the talar neck were treated at the Hospital for Special Surgery between 1981 and 1992. The course of care leading to definitive diagnosis and treatment was reviewed. All five of the patients had night pain relieved by aspirin or nonsteroidal anti-inflammatory drugs. One of the five reported associated trauma. The average time from onset of symptoms to correct diagnosis was 2.5 years. Juxta-articular osteoid osteoma can cause a small spur that resembles a traction spur on the neck of the talus. Anterior ankle impingement was the most common misdiagnosis. Initial treatments included arthroscopic spur debridement or synovectomy, casting for fracture, and repeated nerve blocks for reflex sympathetic dystrophy. The five patients were cured by en bloc excision of the lesion. In the diagnosis of osteoid osteoma, a history of relief of pain with aspirin is important. Plain radiographs and a bone scan are useful. Fine cut computed tomography scanning or magnetic resonance imaging are the best studies for making a definitive diagnosis. Localization by computed tomography guided needle placement or intraoperative radionuclide scanning are recommended to find the lesion for excision. Intraoperative radiographs of the excised lesion should be used to confirm complete removal.

Salvage of pseudoarthrosis after tibiotalar arthrodesis.

We retrospectively reviewed the treatment of a selected group of 23 patients with pseudoarthrosis after ankle arthrodesis who underwent revision arthrodesis at an average of 1.7 years (range, 0.3-17.0 years) after the initial, unsuccessful procedure. Fourteen patients underwent isolated revision tibiotalar arthrodesis, and 9 had an additional hindfoot arthrodesis (7 tibiotalocalcaneal, 2 pantalar) performed at the time of the procedure. Rigid internal fixation with screws was performed when possible, and, in patients with poor bone quality, an external fixator was used. Autogenous bone grafting was used in 14 patients where bone loss was present. Twenty-one of 23 patients had successful union (average, 14 weeks; range, 6-48 weeks). Two patients underwent successful arthrodesis but had persistent pain from reflex sympathetic dystrophy. Overall, 19 of 23 patients were satisfied with the surgery. We conclude that revision arthrodesis for tibiotalar pseudoarthrosis is a worthwhile procedure.

Tension neuropathy of the superficial peroneal nerve: associated conditions and results of release.

We reviewed eight patients who sustained superficial peroneal nerve neuralgia after an inversion ankle sprain. Surgical exploration found anatomic abnormalities that tethered the nerve from movement during plantarflexion and inversion of the ankle. Most patients' pain improved dramatically after release and anterior transposition of the nerve. Seven joints also underwent arthroscopy, which showed intra-articular disease that was consistent with the original trauma. Five patients had reflex sympathetic dystrophy, three of which resolved after nerve release. Nerve conduction studies were not helpful. Careful physical examination and local nerve blocks were most important in making the diagnosis and prescribing treatment. All conservative measures should be exhausted before surgery is considered.

Plantar fasciitis: how successful is surgical intervention?

Forty-three patients (47 heels) underwent decompression of the nerve to abductor digiti minimi with partial plantar fascia release for intractable plantar fasciitis over a 4-year period. Forty-one patients (45 heels) were available for follow-up. All of the patients had failed to respond to nonoperative treatment. The mean duration of symptoms before surgery was 34.8 months (range, 12-132 months), and the mean follow-up was 31.4 months (range, 11-66 months). Seventy percent of the patients in the study were overweight or obese. Before surgery, 39 patients (43 heels) rated their heel pain as severe. At follow-up, 34 of 45 (75.6%) of the heels were pain-free or only mildly painful. The mean visual analogue pain score dropped from 8.5 of 10 preoperatively to 2.5 of 10 postoperatively. Only four patients failed to report an improvement in their activity restrictions, and only one patient had a walking distance of under 100 m after surgery; this patient had been affected by a reflex sympathetic dystrophy. Overall, however, only 20 of 41 patients were totally satisfied with the outcome (48.8%). We recommend that the small group of patients who fail to respond to nonoperative treatment be considered for surgical intervention. The results in terms of symptomatic relief are generally good but in terms of patient satisfaction can only be rated as moderate. The patients should be counseled about the likely outcome of surgery.

Open label gabapentin treatment for pain in multiple sclerosis.

Pain is a frequent and distressing complaint in patients with multiple sclerosis (MS) and may present a difficult therapeutic problem. Conventional therapy is moderately effective and includes, among others, a variety of anticonvulsant medications. Gabapentin (Neurontin) is a new generation antiepileptic drug which appears to be advantageous in treatment of intractable pain of reflex sympathetic dystrophy. This study investigates the benefits of open-label treatment with gabapentin for pain control in 25 patients with MS. Excellent to moderate pain relief was obtained in a substantial number of patients. Throbbing pains and needles, and cramping pains responded best, and dull aching pains responded least to the medication. There was no significant change in distribution and type of pain as a result of this treatment. Mild to moderate side effects were observed. Cautious escalation of the dose of gabapentin is advisable in MS patients. Further clinical trials with larger patient groups are recommended.

Subclavian arterial injury associated with blunt trauma.

Blunt subclavian artery trauma is an uncommon but challenging surgical problem. The purpose of this study was to retrospectively review the management of blunt subclavian artery injuries treated by the Trauma and Vascular Surgery Services at the East Tennessee State University-affiliated hospitals between 1992 and 1998. Six patients with seven blunt subclavian artery injuries were identified. Physical signs indicating blunt subclavian artery injury were pain or contusion around the shoulder joint; fractures of the clavicle, scapula, or ribs; periclavicular hematomas; and ipsilateral pulse or neurologic deficits. Seven subclavian artery injuries were treated-two arterial transections, two pseudoaneurysms, and three intimal dissections. Associated injuries included four clavicle fractures, one humerus fracture, one combined rib and scapular fractures, and two pneumothoraxes. Vascular surgical treatment included three primary arterial repairs, two saphenous vein interposition grafts, and one polytetrafluoroethylene (PTFE) graft. One patient was treated nonoperatively with anticoagulation. No deaths occurred. Morbidity occurred in two patients with chronic upper extremity neuropathy producing prolonged disability from pain and weakness; one patient had reflex sympathetic dystrophy, and the other had a brachial plexus injury. In conclusion, blunt subclavian artery trauma can be successfully managed with early use of arteriography and prompt surgical correction by a variety of vascular techniques. Vascular morbidity is usually low, but long-term disability because of chronic neuropathy may result from associated brachial plexus nerve injury despite a successful arterial repair.

Axillary artery injury from humeral neck fracture: a rare but disabling traumatic event.

Axillary artery injury from blunt trauma to the shoulder is uncommon. Fracture of the neck of the humerus is a rare cause of injury to the axillary artery. Four cases of axillary artery thrombosis from humeral neck fracture are reported. Each of the first 2 patients presented with a pulseless and acutely ischemic limb after a trivial fall. A repair of the axillary artery with saphenous vein interposition graft was performed in the first patient. The extremity was salvaged, but a residual radial and ulnar neurologic deficit persisted. The second patient presented with a pulseless insensate upper extremity accompanied by motor loss. He underwent primary axillary artery repair. Still early in his postoperative course, he has had global brachial plexopathy and is undergoing intensive physical therapy. The third patient had a delayed presentation of brachial plexopathy and sympathetic reflex dystrophy. Arterial reconstruction was not required owing to excellent collateralization. The fourth patient presented with a cool pulseless extremity. His recovery is nearly complete after bypass of the axillary artery with a reversed saphenous vein graft. In addition, a review of the literature revealed 24 cases of axillary artery injury associated with humeral neck fracture. The mean age was 66.6 years. The most common mechanism of injury was a fall (79%). Thirteen patients (46%) presented with a neurologic deficit. Acute ischemia was present in 68%. Physical examination predicted the arterial injury in all but 1 patient. The injured axillary artery was repaired in 26 cases. Revascularization by an interposition graft was the most common procedure. All grafts and reanastomoses were patent and led to limb salvage. Of 9 primary repairs, 3 amputations were performed. Although limb salvage rate was 89%, a good functional outcome was obtained in only half of the patients. A high index of suspicion is required for early diagnosis of axillary artery injury. Despite excellent results of vascular reconstruction, the outcome remains determined by the excessive neurologic morbidity. Recognition of the associated brachial plexus injury is essential to improve the functional outcome of this unusual arterial injury.

'Sympathetically maintained pain.' I. Phentolamine block questions the concept.

Patients with "reflex sympathetic dystrophy" or "causalgia" underwent sympathetic blocks. In protocol A (77 patients), we infused placebo (saline) for 30 minutes followed by phentolamine (35 mg). In protocol B (23 patients), the saline phase was followed by double-blind infusion of phentolamine or phenylephrine (500 micrograms), a second phase of saline, and then the other active drug. We assessed magnitudes of pain and mechanical hyperalgesias on a 0-to-10 pain scale and monitored sensory and sympathetic effects. With protocol A, pain diminished significantly (> or = 50%) during placebo in 22 patients (28.9%) and during phentolamine in seven (9.2%). With protocol B, four patients (17.3%) had relief of pain during placebo, four (17.3%) during phenylephrine, and two (8.7%) during phentolamine. All "phentolamine responders" had progressive pain relief from placebo. Two patients expressed relief during phenylephrine and worsening during phentolamine. Most patients did not respond significantly to saline or drugs. Thus, pharmacologic manipulation of the alpha-1 adrenergic receptor by either agonist or antagonist drug does not influence neuropathic pains. These results raise questions about the existence of "sympathetically maintained pain," as diagnosed by sympathetic blocks improperly controlled for placebo.

Phentolamine sympathetic block in painful polyneuropathies. II. Further questioning of the concept of 'sympathetically maintained pain'.

To test for the presence of "sympathetically maintained pain" (SMP), we administered placebo-controlled phentolamine sympathetic blocks to 14 patients with painful polyneuropathies. Six received i.v. infusion of saline for 30 minutes, followed by phentolamine (35 mg). In eight patients, the saline phase was followed by double-blind infusion of phentolamine or phenylephrine (500 micrograms), a second saline phase, and then the other active drug. We measured magnitudes of spontaneous pain and mechanical hyperalgesias on a 0-to-10 pain scale every 5 minutes and monitored sensory and sympathetic effects clinically and through quantitative thermotest and thermography. Five patients reported significant diminution of pain (> 50%), all in response to placebo. Neither phentolamine nor phenylephrine provided relief, although all patients had signs of physiologic abnormalities reputed to be determinants or predictors of SMP. These results complement previous studies demonstrating the nonexistence of SMP among "reflex sympathetic dystrophy" patients and further question the concept of SMP.

Subtalar arthrodesis with internal compression for post-traumatic arthritis.

We studied retrospectively the results in 24 patients (25 feet) who had been treated by subtalar arthrodesis with internal compression for post-traumatic arthritis from 1988 to 1992. Fifteen patients were men (16 feet) and nine (9 feet) were women. Their mean age was 43 years (22 to 68), and the average duration of follow-up was four years (2 to 6). A single compression screw was used in all feet and iliac-crest bone grafting in ten. Union was achieved in 24 of the 25 feet (96%). Based on a clinical scale the results were excellent in 10 feet, good in 7, fair in 6, and poor in 2 and on the Angus and Cowell score they were good in 19 feet, fair in 4, and poor in 2. The two poor results were due to nonunion in one patient and reflex sympathetic dystrophy in the other. One reoperation was performed for nonunion. Eighteen patients (18 feet) were satisfied with the results, four were satisfied with reservations, and three were dissatisfied. Progressive ankle and midfoot arthritis did not occur in the absence of pre-existing degenerative changes in these joints. We conclude that isolated subtalar arthrodesis with internal compression was effective treatment for post-traumatic subtalar arthritis. Iliac-crest bone grafting was not routinely required.

Osteotomy of the radius and ulna for the Madelung deformity.

The Madelung deformity can result in pain and decreased function of the wrist and hand. None of the surgical techniques available has been shown consistently to improve grip strength, range of movement or relieve pain. In this prospective study we have treated 18 patients with the Madelung deformity (25 wrists) by wedge subtraction osteotomy of the radius and shortening of the ulna. Our results show statistically significant improvement in grip strength and range of movement of the wrist and forearm. Pain improved in 80% of the patients and 88% were satisfied with the appearance. One patient had a wound infection and another developed reflex sympathetic dystrophy. Two had some recurrence due to continued growth of the ulna and it is recommended that the procedure be delayed until skeletal maturity, or else combined with epiphysiodesis of the ulna.

Management of recurrent, complex instability of the elbow with a hinged external fixator.

We have treated 16 patients with recurrent complex elbow instability using a hinged external fixator. All patients had instability, dislocation or subluxation of the ulnohumeral joint. The injuries were open in eight patients and were associated with 20 other fractures and five peripheral nerve injuries. Two patients had received initial treatment from us; 14 had previously had a mean of 2.1 unsuccessful surgical procedures (1 to 6). The fixator was applied at a mean of 4.8 weeks (0 to 9) after the injury and remained on the elbow for a mean of 8.5 weeks (6 to 11). After treatment we found the mean range of flexion-extension to be 105 degrees (65 to 140). At a final follow-up of 23 months (14 to 40), the mean Morrey score was 84 (49 to 96): this translated into one poor, three fair, ten good and two excellent results. Complications included one fractured humeral pin, one temporary palsy of the radial nerve, one recurrent instability, one wound infection, one severe pin-track infection and one patient with reflex sympathetic dystrophy. Although technically demanding, the use of the fixator is an important advance in the management of recurrent complex elbow instability after failure of conventional treatment.

Transient osteoporosis of the knee following trauma.

Transient osteoporosis is an uncommon, self-limiting, reversible condition. We report a case involving the knee following trauma. The aetiology is unknown, but the association between transient osteoporosis and trauma has not been documented previously. The clinical presentation represents a degree of overlap among various clinical syndromes, including reflex sympathetic dystrophy and avascular necrosis. The diagnosis was confirmed by bone scan and MRI. The patient, a 47-year-old man, was treated with non-steroidal anti-inflammatory medication, protected weight-bearing and physiotherapy. He made a full clinical recovery and bone quality returned to virtual normality.

Exposure of the head of the radius using the Wrightington approach.

Surgical access to the head of the radius is usually performed through a lateral approach. We present an alternative technique through a modified posterior approach which was developed following dissections of 22 human cadavers. An osteotomy of the supinator tuberosity was performed and reflected as a single unit with the attached annular ligament. Excellent exposure of the head of the radius was achieved, replacement of the head was undertaken and the osteotomy site repaired. The elbows were stable and had a full range of movement. The approach was then carried out on 13 patients for elective replacement of the head and was found to be safe and reproducible. In the patient group all osteotomies united, the elbows were stable and had an improved range of supination and pronation. There was no change in flexion and extension of the elbow. Complications included a haematoma and a reflex sympathetic dystrophy. The modified posterior approach provides excellent access to the head and neck of the radius, gives good stability of the elbow and allows early mobilisation of the joint.

The effect of alendronate on bone mass after distal forearm fracture.

Fracture and immobilization of an extremity lead to bone loss at the fracture and at adjacent sites. We conducted a 1-year, single-center, prospective, randomized, double-blind study to determine whether bone loss would occur in the distal radius after a Colles' fracture and whether this loss could be prevented using an antiresorptive drug (alendronate). Thirty-seven women with a recent fracture of the distal forearm and low bone mineral density (BMD) of the lumbar spine were randomized to receive either 10 mg alendronate daily or placebo. BMD of both forearms was measured at baseline and after 3, 6, and 12 months. The results of four women who developed reflex sympathetic dystrophy were not included in the analysis. In the placebo group, there was a significant reduction at 3 months and 6 months in BMD of total radius (p < 0.01), one-third distal radius (p < 0.01), middistal radius (p < 0.05), and ultradistal radius (p < 0.01) on the fractured side. The loss in BMD at one-third distal radius remained significant at month 12 (p < or = 0.001). In the alendronate group BMD of total distal radius, one-third distal radius, and middistal radius at the fractured side remained unchanged. BMD of ultradistal radius increased significantly at months 3, 6, and 12, compared with baseline (p < 0.05). The difference between the two treatment groups was significant at 3 months and 6 months and borderline significant (p = 0.054) after 1 year in total distal radius. In ultradistal radius the differences were significant at all time points. We conclude that BMD of the distal radius of a recently fractured forearm decreases significantly in the 6 months after fracture and the resulting deficit remains evident at least 1 year after fracture. This bone loss can be prevented by alendronate.

Ziconotide infusion for severe chronic pain: case series of patients with neuropathic pain.

Ziconotide intrathecal infusion was recently approved by the United States Food and Drug Administration for the treatment of intractable severe chronic pain. Patients with neuropathic pain make up a significant population among those who experience chronic pain for which there are less than optimal pharmacotherapeutic options. Published clinical trials provide a global view of ziconotide efficacy and safety. A subset of patients in clinical trials obtained complete pain relief, a remarkable finding given the history of drug treatment for neuropathic pain. To provide more information regarding those who respond to ziconotide therapy, we discuss three patients with neuropathic pain who received ziconotide infusion. Two patients with longstanding neuropathic pain, one with complex regional pain syndrome (formerly known as reflex sympathetic dystrophy) of the leg and one with lumbar radiculitis, achieved temporary but complete pain relief from single 5- and 10-microg epidural test doses. In the third case, a patient with longstanding bilateral leg and foot neuropathic pain from acquired immunodeficiency syndrome and antiretroviral drug therapy achieved considerable pain relief from a long-term continuous intrathecal infusion. The patients who received a single dose had mild central nervous system adverse effects such as sedation, somnolence, nausea, headache, and lightheadedness. The patient who received the intrathecal infusion experienced mild-to-severe adverse effects depending on the rate of infusion; these effects included sedation, confusion, memory impairment, slurred speech, and double vision. This patient could sense impending adverse effects and made rate adjustments or suspended infusion to avert untoward symptoms. In all three cases, patients achieved considerable pain relief that was long-lasting and persisted well after dose administration or suspension of infusion.

Results of arthrodesis of the tarsometatarsal joints after traumatic injury.

We retrospectively reviewed the records of thirty-two patients who had had an arthrodesis of the tarsometatarsal joints for intractable pain after a traumatic injury of the midfoot. The arthrodesis was performed at a mean of thirty-five months (range, six to 108 months) after the injury. All of the procedures were performed with use of rigid internal fixation, and twenty-four patients, in whom a defect had been created by debridement of the joints, were managed with an autogenous bone graft. Nine patients had at least one concomitant procedure, including a claw-toe procedure (eight patients), a reconstruction of the posterior tibial tendon (three patients), an excision of an interdigital neuroma (three patients), an arthrodesis of the calcaneocuboid joint (one patient), and an arthrodesis of the ankle (one patient). Complications included neuritis in three patients; metatarsalgia in two; malunion in two; and asymptomatic non-union, wound slough, superficial infection, and reflex sympathetic dystrophy in one each. The patients were evaluated at a mean of fifty months (range, twenty-four to 105 months) after the arthrodesis. The evaluation included a physical examination, radiographs, and use of the rating scale of the American Orthopaedic Foot and Ankle Society for the evaluation of the midfoot. The mean postoperative score of 78 (of a possible 100) points was significantly better than the mean preoperative score of 44 points (p = 0.02). With the numbers available, we could not show that the extent of the arthrodesis, the involvement of other joints in the hindfoot or the forefoot, the mechanism of injury, or whether the injury was work-related significantly affected the functional outcome.
