Local infiltration analgesia (LIA) is promoted as an effective treatment modality for pain control after total knee arthroplasty (TKA) (1). A mixture of drugs is used to provide a multimodal analgesic effect. Previous studies reported that the use of these drugs is safe. After we carefully implemented a LIA study protocol in our practice, concerns raised about patient safety with probably higher infection rates. This forced us to perform an interim analysis after the first 58 cases. 58 patients underwent a unilateral TKA with a standardised LIA protocol (2), which consisted of a mixture of ropivacaine, epinephrine, and triamcinolone acetonide. Complications, knee function and patient satisfaction scores were prospectively recorded during regular outpatient control. Four patients (6.9%) presented with signs of periprosthetic joint infection (PJI) within two months after surgery. Baseline characteristics were similar between the infected and non infected group. All infections were treated with debridement and retention, and antimicrobial treatment was started. One patient who suffered an infection died during followup. At two years followup all implants could be retained. Knee function and KSS score were acceptable for the patients who suffered PJI. There is no consensus on the combination of drugs used for LIA. The application of corticosteroids in LIA is reported to be safe (3), but arguable results about the injection of
Aims: To assess prospectively the effectiveness and safety of Cortossª, a new synthetic, biocompatible, highly radiopaque composite in the percutaneous augmentation of vertebral compression fractures. Methods: Patients with severe pain (>
50mm VAS) associated to radiographic evidence of osteoporotic or malignant vertebral compression fracture(s). Cortoss was injected with the help of a syringe-catheter system introduced into a 10 to 11-gauge needle under continuous ßuoroscopic control. All leakages and adverse events were to be reported. Assessments were made before vertebroplasty (bv) and after 3 days (3d), 1 week (1w), 1 month (1m), 3 (3m) and 6 months (6m). Results: Fifty-eight interventions were performed in 53 patients. Mean pain scores (mm VAS) decreased from 69 (bv) to 39 (3d), 39 (1w), 31 (1m), 23 (3m), 26 (6m). A mean (range) of 4.3 (1.5–8) mL of Cortoss was injected per vertebral body. Augmented vertebral bodies remained stable over time. Leakage of Cortoss occurred in 76% of interventions. No pulmonary emboli or persistent nerve root or medullary irritation occurred in association to leakage of Cortoss. One patient required
The aim of the study is to assess the humero radial plica which could be a factor in causing lateral elbow pain. The cause of lateral elbow pain has been an enigma for the orthopaedic surgeons over the years. The synovial fold of the humeroradial joint has been well documented and considered as a meniscus between the articulation. They can also present as symptoms suggesting intra articular loose bodies causing pain in these patients. Our study included 117 consecutive elbow arthroscopies performed by two surgeons for a period of 18 months. All patients were initially treated non-operatively as a ‘tennis elbow’ before undergoing arthroscopy. Conservative treatment included rest, activity modification, physiotherapy including ultrasound bracing, nsaids and
Introduction: Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve, mainly associated with either injury or pressure to the nerve. Although this entity is well described, most clinical series have employed numerous treatment methods; therefore, the efficacy of individual modalities is unclear. We describe our experience of 79 patients with complaints consistent with MP, treated, by the senior author, over a 13-year period. Materials and Methods: Patients were managed in accordant to a structured protocol:. Initial management consisted of anti inflammatory agents, rest and redaction of aggravating factors. Diagnostic nerve block test was carried out for those who were refractory to the above treatment. All patients who responded to the local anesthetic test were treated with local infiltration of corticosteroids. Surgical intervention was reserved for patients who responded to the lidociane test but were refractory to repeated corticosteroids injections. Patients who failed to respond to the test injection were evaluated by CT-scan of the lumbar spine and by abdominal ultrasound (for female patients only). Follow-up ranged 1–13 years. Results: Twenty-one patients (27%) reported satisfactory results flowing initial management. Local anesthetic yielded rapid relief of symptoms in 50 patients (86%), two additional patients responded to a second nerve block test (where a wider area was infiltrated). In forty-two out of 52 patients (81%) who responded to the nerve block test and received treatment with corticosteroid injections, Long-lasting relief was obtained. Three patients refractory to repeated injections of corticosteroid underwent surgery (neurolysis in one patient and nerve resection in two). CT-scan of the lumbar spine revealed significant spinal stenosis and nerve root compression at the level of L1–3 in 3 out of 6 patients. Conclusion: Idiopathic MP usually improves with nonoperative modalities. Temporary relief of symptoms following LFCN block is a specific diagnostic test, and is a good predictor of success following
A local injection may be used as an early option in the treatment of Morton’s neuroma, and can be performed using various medications. The aim of this study was to compare the effects of injections of hyaluronic acid compared with corticosteroid in the treatment of this condition. A total of 91 patients were assessed for this trial, of whom 45 were subsequently included and randomized into two groups. One patient was lost to follow-up, leaving 22 patients (24 feet) in each group. The patients in the hyaluronic acid group were treated with three ultrasound-guided injections (one per week) of hyaluronic acid (Osteonil Plus). Those in the corticosteroid group were treated with three ultrasound-guided injections (also one per week) of triamcinolone (Triancil). The patients were evaluated before treatment and at one, three, six, and 12 months after treatment. The primary outcome measure was the visual analogue scale for pain (VAS). Secondary outcome measures included the American Orthopaedic Foot and Ankle Society (AOFAS) score, and complications.Aims

Background Adhesive capsulitis of the shoulder is a painful condition that results in gradual loss of joint movement. Numerous treatment modalities have been utilised with variable benefits. Because of the risk of brachial plexus injury and fracture, manipulation under anaesthesia is considered with caution. Aim To determine the rate of manipulation under anaesthesia (MUA) following primary distension arthrogram for adhesive capsulitis of the shoulder. Patients and Methods The case notes of 40 patients (42 shoulders) between 1998 to 2004 at Glenfield Hospital, Leicester under the care of one consultant with adhesive capsulitis of the shoulder treated with distension arthrogram by using intra-articular injection of
We aimed to establish the short- and long-term efficacy of corticosteroid injection for coccydynia, and to determine if betamethasone or triamcinolone has the best effect. During 2009 to 2016, we treated 277 patients with chronic coccydynia with either one 6 mg betamethasone or one 20 mg triamcinolone cortisone injection. A susequent injection was given to 62 (26%) of the patients. All were reviewed three to four months after injection, and 241 replied to a questionnaire a mean of 36 months (12 to 88) after the last injection. No pain at the early review was considered early success. When the patient had not been subsequently operated on, and indicated on the questionnaire that they were either well or much better, it was considered a long-term success.Aims
Methods
Although periarticular injection plays an important role in multimodal pain management following total hip arthroplasty (THA), there is no consensus on the optimal composition of the injection. In particular, it is not clear whether the addition of a corticosteroid improves the pain relief achieved nor whether it is associated with more complications than are observed without corticosteroid. The aim of this study was to quantify the safety and effectiveness of cortocosteroid use in periarticular injection during THA. We conducted a prospective, two-arm, parallel-group, randomized controlled trial involving patients scheduled for unilateral THA. A total of 187 patients were randomly assigned to receive periarticular injection containing either a corticosteroid (CS group) or without corticosteroid (no-CS group). Other perioperative interventions were identical for all patients. The primary outcome was postoperative pain at rest during the initial 24 hours after surgery. Pain score was recorded every three hours until 24 hours using a 100 mm visual analogue scale (VAS). The primary outcome was assessed based on the area under the curve (AUC).Aims

The aim of this study was to compare the efficacy of a corticosteroid injection for the
treatment of carpal tunnel syndrome (CTS) in patients with and without Raynaud’s
phenomenon. In a prospective study, 139 patients with CTS were treated with a corticosteroid
injection (10 mg triamcinolone acetonide); 34 had Raynaud’s phenomenon and 105
did not (control group). Grip strength, perception of touch with a Semmes-Weinstein
monofilament and the Boston Carpal Tunnel Questionnaires (BCTQ) were assessed at
baseline and at six, 12 and 24 weeks after the injection. The Cold Intolerance Severity
Score (CISS) questionnaire was also assessed at baseline and 24 weeks after the
injection.Aims
Patients and Methods
Complications of distal radius fractures range from 20 to 30% and are consequence of injury or of treatment. Management of these complications must be individualised and the multitude of proposal treatments prove that this problem is controversial. Complications may involve soft tissue (tendon, nerve, arterial or fascial complication, reflex symphatetic distrophy) or bone and joint (malunion, nonunion, osteoarthritis). Tendon complications following distal radius fractures, range from minor adhesions to complete rupture. Peritendinous adhesions will become apparent after cast removal. Diagnosis is based on the limitation of the range of movement for individual fingers.This complication can be avoided with a proper cast technique allowing full range of motion to the digits. Treatment consists of rehabilitation techniques and only rarely, in severe cases, operative tenolysis may be a treatment of choice. Tendons may be entrapped either in the fracture site or in the distal radioulnar joint. Most common tendon entrapment are for extensor carpi ulnaris and extensor digiti minimi. If early recognition is made, open reduction with freeing the tendon must be the choice. Late diagnosis will require more complex tenolysis procedures. Tendon rupture may occur at the time of injury due to sharp fracture fragments. Diagnosis is based on identification of functional loss and, whenever possible, primary tendon suture is recommended. If the diagnosis is late the treatment is free tendon graft or tendon transfer. The late rupture of extensor pollicis longus is the most common possibility. Since it is not related with comminution or displacement of fracture it is possible that an ischemic mechanism is involved. Solutions are free tendon graft or the transfer of extensor indicis proprius. Direct tendon repair is not recommended after few weeks. Nerve complications. Careful neurological investigations demonstrated that nerve injuries associated with distal radius fractures are more common than it is believed. Median nerve is most frequently involved. Primary mechanisms of injury are: direct lesions due to fracture fragments, lesions related to forced manipulation and nonanatomical position of immobilization. Late injuries, occurring a long time after the fracture are more frequent and are related to carpal tunnel syndrome or paraneural adhesions. Carpal tunnel pressure could be measured and ethiologic factors must be identificated in order to establish the proper treatment, usually based on relise of carpal tunnel. Ulnar and radial neuropathy are less common and treatment may vary from cast removal to relise of Guyon’s canal. Vascular complications are uncommon, arise usually in relation with high energy trauma and the treatment is complex, involving different speciality surgeons. Some authors presented rare cases of entrapment of vasculare structures or radial artery pseudoaneurism after the use a volar plate. Compartment syndrome after distal radius fracture is rare and is likely to occur in young adults suffering a high energy trauma. Clinical diagnosis is based on the classical 5 “P’s” (pain, pallor, paresthesias, paralysis, and pulselessness) but treatment must start before all symptoms are present. Anytime when compartment syndrome is suspected, intracompartimental pressure must be measured. The treatment must start immediately and consist in removal of constrictive devices (bandage, cast) and fasciotomy. Indications for fasciotomy are intracompartmental pressure of 15–25mmHg in presence of clinical signs or over 25mmHg in absence of clinical signs. If there is doubt, it is better to perform an unnecessary fasciotomy than to wait until lesions becomes irreversible. Reflex sympathetic distrophy is described with many terms such as algodistrophy, cauzalgia, Sûdeck’s atrophy, shoulder-hand syndrome. Recently, the term complex regional pain syndrome was proposed to replace all the exiting synonyms. Despite many theories, the pathogeny of this disease is uncertain. The diagnosis is mainly clinical, based on presence of pain, trophic changes (atrophy, stiffness, edema) and functional impairment but plain x-ray demonstrating osteopenia and bone scintigraphy showing abnormal bone turnover may be helpful. Since the patogeny is unclear, the treatment is targeting the symptoms rather then the disease. Treatment must be individualized and may consist of: physical therapy of the hand, pain control with general or

Peri-tendinous injection of local anaesthetic,
both alone and in combination with corticosteroids, is commonly performed
in the treatment of tendinopathies. Previous studies have shown
that local anaesthetics and corticosteroids are chondrotoxic, but
their effect on tenocytes remains unknown. We compared the effects
of lidocaine and ropivacaine, alone or combined with dexamethasone,
on the viability of cultured bovine tenocytes. Tenocytes were exposed
to ten different conditions: 1) normal saline; 2) 1% lidocaine;
3) 2% lidocaine; 4) 0.2% ropivacaine; 5) 0.5% ropivacaine; 6) dexamethasone
(dex); 7) 1% lidocaine+dex; 8) 2% lidocaine+dex; 9) 0.2% ropivacaine+dex;
and 10) 0.5% ropivacaine+dex, for 30 minutes. After a 24-hour recovery
period, the viability of the tenocytes was quantified using the
CellTiter-Glo viability assay and fluorescence-activated cell sorting
(FACS) for live/dead cell counts. A 30-minute exposure to lidocaine
alone was significantly toxic to the tenocytes in a dose-dependent
manner, but a 30-minute exposure to ropivacaine or dexamethasone
alone was not significantly toxic. Dexamethasone potentiated ropivacaine tenocyte toxicity at higher
doses of ropivacaine, but did not potentiate lidocaine tenocyte
toxicity. As seen in other cell types, lidocaine has a dose-dependent
toxicity to tenocytes but ropivacaine is not significantly toxic.
Although dexamethasone alone is not toxic, its combination with
0.5% ropivacaine significantly increased its toxicity to tenocytes.
These findings might be relevant to clinical practice and warrant
further investigation.
Injection or aspiration of the ankle may be performed through either an anteromedial or an anterolateral approach for diagnostic or therapeutic reasons. We evaluated the success of an intra-articular puncture in relation to its site in 76 ankles from 38 cadavers. Two orthopaedic surgical trainees each injected methylene blue dye into 18 of 38 ankles through an anterolateral approach and into 20 of 38 through an anteromedial. An arthrotomy was then performed to confirm the placement of the dye within the joint. Of the anteromedial injections 31 of 40 (77.5%, 95% confidence interval (CI) 64.6 to 90.4) were successful as were 31 of 36 (86.1%, 95% CI 74.8 to 97.4) anterolateral injections. In total 62 of 76 (81.6%, 95% CI 72.9 to 90.3) of the injections were intra-articular with a trend towards greater accuracy with the anterolateral approach, but this difference was not statistically significant (p = 0.25). In the case of trainee A, 16 of 20 anteromedial injections and 14 of 18 anterolateral punctures were intra-articular. Trainee B made successful intra-articular punctures in 15 of 20 anteromedial and 17 of 18 anterolateral approaches. There was no significant difference between them (p = 0.5 and p = 0.16 for the anteromedial and anterolateral approaches, respectively). These results were similar to those of other reported studies. Unintended peri-articular injection can cause complications and an unsuccessful aspiration can delay diagnosis. Placement of the needle may be aided by the use of ultrasonographic scanning or fluoroscopy which may be required in certain instances.
Intra-articular punctures and injections are performed routinely on patients with injuries to and chronic diseases of joints, to release an effusion or haemarthrosis, or to inject drugs. The purpose of this study was to investigate the accuracy of placement of the needle during this procedure. A total of 76 cadaver acromioclavicular joints were injected with a solution containing methyl blue and subsequently dissected to distinguish intra- from peri-articular injection. In order to assess the importance of experience in achieving accurate placement, half of the injections were performed by an inexperienced resident and half by a skilled specialist. The specialist injected a further 20 cadaver acromioclavicular joints with the aid of an image intensifier. The overall frequency of peri-articular injection was much higher than expected at 43% (33 of 76) overall, with 42% (16 of 38) by the specialist and 45% (17 of 38) by the resident. The specialist entered the joint in all 20 cases when using the image intensifier. Correct positioning of the needle in the joint should be facilitated by fluoroscopy, thereby guaranteeing an intra-articular injection.
