PMID: 25779715 DOI: 10.5505/tjtes.2015.27475

A rare case of bilateral anterior hip dislocation reduced under sedation was reported in this study. A 47-year-old man was knocked down by a car and sustained bilateral anterior hip dislocation which was reduced successfully with sedation using titrated dose of intravenous Midazolam in combination with Pethidine. A modified Lefkowitz maneuver using the manipulator's thigh as a fulcrum was used. Patient started weight bearing in the second month after injury and was walking without any hip pain at the twenty-fourth month follow-up. Thirteen case reports describing bilateral anterior hip dislocations were found while reviewing the literature and it was noticed that only one author had reported the usage of intravenous sedation (Propofol) for the reduction procedure. However, no author reported the use of Lefkowitz maneuver for this purpose. Consequently, reduction of a bilateral anterior hip dislocation is possible with sedation using a modified Lefkowitz maneuver.

Fulltext Fat embolism in right internal jugular vein: incidental ultrasound finding during internal jugular vein cannulation

Adi O, Fong CP, Azil A, Wahab SFA

Ultrasound J, 2019 Feb 25;11(1):1.

PMID: 31359296 DOI: 10.1186/s13089-019-0116-9

BACKGROUND: We report a case study of fat embolism seen on ultrasound at right internal jugular vein during central venous cannulation in a patient diagnosed with fat embolism syndrome. This case demonstrates the importance of ultrasound for evaluation of trauma cases with suspicion of fat embolism.

CASE PRESENTATION: A 23-year-old trauma patient with closed fracture of left femoral shaft and left humerus presented to our emergency department (ED). 11 h after admission to ED, patient became confused, hypoxic and hypotensive. He was then intubated for respiratory failure and mechanically ventilated. Transesophageal ultrasound revealed hyperdynamic heart, dilated right ventricle with no regional wall abnormalities and no major aorta injuries. Whole-body computed tomography was normal. During central venous cannulation of right internal jugular vein (IJV), we found free floating mobile hyperechoic spots, located at the anterior part of the vein. A diagnosis of fat embolism syndrome later was made based on the clinical presentation of long bone fractures and fat globulin in the blood. Despite aggressive fluid resuscitation, patient was a non-responder and needed vasopressor infusion for persistent shock. Blood aspirated during cannulation from the IJV revealed a fat globule. Patient underwent uneventful orthopedic procedures and was discharged well on day 5 of admission.

CONCLUSIONS: Point-of-care ultrasound findings of fat embolism in central vein can facilitate and increase the suspicion of fat embolism syndrome.

Fulltext Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation and analgesia in the emergency department

Jamal SM, Fathil SM, Nidzwani MM, Ismail AK, Yatim FM

Med J Malaysia, 2011 Aug;66(3):231-3.

PMID: 22111446

The study compared the effectiveness of ketamine and midazolam/fentanyl as procedural sedation and analgesia agents for reduction of fractures and dislocated joints. Forty-one adult patients were enrolled by convenience sampling. They were randomized to receive ketamine or midazolam/fentanyl. Depth of sedation, pain score, procedural outcome and memory of the procedure were documented. The ketamine group had deeper sedation, but there was no statistical difference in other variables between the two groups. Three patients in the midazolam/fentanyl group had oxygen desaturation. More adverse effects were associated with ketamine. Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation.

Fulltext The comparison of discomfort level between upper arm and forearm tourniquet

Ng ES, Ting JR, Foo SL, Akram SA, Fadzlina AA, Alywiah JS, et al.

Med J Malaysia, 2006 Dec;61 Suppl B:23-6.

PMID: 17600989

The conventional upper arm tourniquet used for hand and wrist operations may cause significant discomfort to patient when the procedure is performed under local anaesthesia. Forearm tourniquet causes less muscle ischeamia and pain. The discomfort experienced while using a forearm and upper arm tourniquet was assessed in 96 healthy subjects. Tourniquet placed on both sides was inflated sequentially to 250mmhg for five minutes on different hand. The discomfort level was assessed using a small visual analogue scale and complications were recorded. In the upper arm tourniquet, 24.9% had mild, 60.5% had moderate and 14.6% had severe pain whereas with forearm tourniquet, 99% had mild pain and only 1% had moderate pain. Seventy-nine percent of the subjects tested with forearm tourniquet had no discomfort at all. The average discomfort level for upper arm and forearm tourniquet was 4.72 and 0.39 respectively, which is statistically significant. Complications that were observed only in upper arm tourniquet included prolonged tingling, burning sensation and discomfort and stiffness of the upper limb. We concluded that forearm tourniquet was safe and well tolerated and should be used more often when indicated.

Fulltext The rate of glove perforations in orthopaedic procedures: single versus double gloving. A prospective study

Chan KY, Singh VA, Oun BH, To BH

Med J Malaysia, 2006 Dec;61 Suppl B:3-7.

PMID: 17605178

Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves worn by the surgical team were assessed after the surgery using the water-loading test. A total of 1452 gloves were tested, and the rate of perforation was 3.58%. Most of these perforations (61.5%) were unnoticed. The main surgeons had the most perforations (76.9%), followed by first assistants (13.5%) and second assistants (9.6%). Most perforations occurred at the non-dominant hand. The commonest site of perforation was the index finger followed by the thumb. Shearing force with instruments accounted for 45% of the noticed perforations. Majority of these occurred during nailing procedures (33%) and internal fixation without the use of wires (19%). Our rate of glove perforation is similar to other series. Most of them went unnoticed and were mainly due to shearing injuries rather than perforation by sharps. Therefore, there is an increased risk of contamination and break in asepsis during surgery.

Fulltext Prophylactic antibiotics in orthopaedic surgery: guidelines and practice

Yeap JS, Lim JW, Vergis M, Au Yeung PS, Chiu CK, Singh H

Med J Malaysia, 2006 Jun;61(2):181-8.

PMID: 16898309

The national clinical practice guideline has recommended that prophylactic antibiotic be given in orthopaedic surgery involving joint replacements and internal fixation of fractures. The aim of this study is to assess the current antibiotics prophylaxis practice in a state level hospital. One hundred and three patients (68 males, 35 females; mean age 41.6 +/- 22.2 years) undergoing internal fixation for closed fractures and joint replacement surgery were included in this prospective study. The choice of pre and post-operative antibiotics, their dosages and duration of administration were recorded. The pre-operative antibiotics were only deemed to have been given if it was documented in the case notes and in the case of post-operative antibiotics if it was signed on the drug chart. Eighty eight percent were given pre-operative prophylactic antibiotics and 92% were given post-operative antibiotics. For patients undergoing internal fixation of fractures, the most commonly used antibiotic for both pre and post-op is intravenous cefuroxime. For joint replacement surgery, the most commonly used antibiotic is intravenous cefoperazone. The duration or number of doses of post-operative antibiotics was highly variable. It was not stated in 56% of the post-operative instructions. Post-operative antibiotic was ordered for 48 hours or longer in 10%. In conclusion, prophylactic antibiotics appear to be widely practised. The first line antibiotics as recommended by the present guideline were not given in any of the patients. Second generation followed by third generation cephalosporins are the most popular antibiotics, with a trend towards using third generation cephalosporins in arthroplasty patients. Single dose prophylaxis was rarely practised.

Fulltext Revision surgery for developmental dysplasia of the hip

Chidambaram S, Abd Halim AR, Yeap JK, Ibrahim S

Med J Malaysia, 2005 Jul;60 Suppl C:91-8.

PMID: 16381291

Revision surgery following failed open reduction for developmental dysplasia of the hip (DDH) is technically demanding. We reviewed 12 patients in our institution that required a revision surgery between January 1994 and December 2003. The aims of this study are to identify the causes of redislocation after the primary open reduction and to determine the clinical and radiological outcome after the revision surgery. The mean age at presentation for DDH was 31 months (range 1-84) and the mean age at primary open reduction surgery was 38 months (range 15-84) and the mean age at revision surgery was 69 months (range 21-180). The mean follow-up period after revision surgery was 20 months (range 3-84). All the revision surgery was performed via an anterior Smith Peterson approach. The most common cause for redislocation was inadequate exposure and failure to release the obstructing soft tissues around the hip. The bony factors for redislocation included failure to perform a femoral shortening and excessive derotation of an anteverted femoral head combined with a Salter osteotomy. Three cases with posterior acetabular wall deficiency needed immobilization of the hip in extension as the hip tended to dislocate in flexion. Six patients had limb length discrepancy ranging from 1 cm to 4 cm and 50% developed avascular necrosis. Only 2 patients were asymptomatic and the majority had a limp and limitation of motion. All were pain free except one. In view of the technically demanding surgery and poor results after revision, the surgeon should recognize the pathology and ensure that the primary procedure achieves a stable and concentric reduction.

In vitro development of autologous tissue engineered human articular neocartilage for orthopaedic surgery

Samsudin OC, Aminuddin BS, Munirah S, Chua KH, Fuzina NH, Isa MR, et al.

Med J Malaysia, 2004 May;59 Suppl B:15-6.

PMID: 15468796

Treatment of articular cartilage lesions remains a clinical challenge. The uses of prosthetic joint replace allograft and/or autograft transplant carry a risk of complications due to infection, loosening of its component, immunological rejection and morbidity at the donor site. There has been an increasing interest in the management of cartilage damages, owing to the introduction of new therapeutic options. Tissue engineering as a method for tissue restoration begins to provide a potential alternative therapy for autologous grafts transplantations. We aimed to evaluate how well a tissue engineered neocartilage implant, consist of human articular chondrocytes cultured with the presence of autologous serum and mixed in a fresh fibrin derived from patient, would perform in subcutaneous implantation in athymic mice.

PMID: 15941172

The clinical presentation and behaviour of giant cell tumour of bone vary. The progression of the disease and metastasis are unpredictable, but the overall prognosis is good. Six patients with pulmonary metastases of giant cell tumour have been treated at our institution since 1998. This represents 15% of all patients treated for giant cell tumour of the bone. Early detection and treatment of this tumour is important as complete resection of this tumour have favourable prognosis. Multiple lung nodules which preclude resection may remain dormant and asymptomatic with systemic chemotherapy.

PMID: 15941163

Sleeve fracture of the inferior pole of the patella is a rare and distinctive fracture in children with few published reports. These fractures are frequently misdiagnosed and neglected. We highlight a case of a neglected and misdiagnosed sleeve fracture of the patella in an eleven-year-old boy. This was initially diagnosed as an avulsion fracture of the tibial tubercle. A good outcome was achieved after open reduction and internal fixation.

Fulltext Orthopaedic infections: organisms and antibiotic sensitivity

Yusof MI, Yusof AH

Med J Malaysia, 2004 Dec;59(5):574-7.

PMID: 15889557

Staphylococcus aureus infection remains the commonest organism causing musculoskeletal infection and antibiotic is the mainstay of treatment apart from adequate and appropriate surgical intervention. The exact figure of antibiotic resistance in orthopaedic practice is not known but it is expected to be higher than previously reported as the use of antibiotics is rampant. Its sensitivity to various antibiotics differs from one center to another making local surveillance necessary. From 66 patients with musculoskeletal infections studied in our centre, Staphylococcus aureus was cultured in 50-65% of patients, depending on the sample taken. Fifteen percent of this were methicillin resistant Staphylococcus aureus (MRSA). Staphylococcus aureus was found to be sensitive to cloxacillin in 95% of patients' sample. MRSA remained highly sensitive to vancomycin, clindamycin and fucidic acid.

PMID: 10968190

We studied 95 patients who underwent knee Arthroscopy under local anaesthesia between JANUARY 1995 till 1997. Materials used were 1% Xylocaine and 0.25% Bupivacaine of 20 mls each combined with midazolam 2 mg and IV pethidine 30 mgm for sedation. The patients were attached to monitors (pulse Oxymeter, ECG and BP and pulse recorders) and blood less field was created using a tornquet. The procedures lasted about 45 minutes. 90 out of 95 patients completed the procedures successfully without any complications. 2 developed respiratory embarrassments and were intubated and ventilated. 3 procedures abandoned and converted to general anaesthesia. The range of procedures done include meniscectomy, meniscal repair, synovial biopsy, debridement for osteoarthrosis, shaving of osteophytes, drilling of cartilage and bones and removal of loose bodies. This study is to show that knee arthroscopy under LA is a safe alternative in hospitals where GA time is limited.

Leow HK, Hyzan Y, Gan EC, Hassan S

Med J Malaysia, 1998 Sep;53 Suppl A:71-6.

PMID: 10968185

Acromio-clavicular joint (ACJ) dislocation usually occurs in young adults following trauma or sports injury. Fourteen patients underwent surgical treatment for symptomatic total ACJ dislocation (Rockwood and Matsen Type III-VI) in our unit between January 1996 and June 1997. Eight patients were operated within three weeks of injury and six in the chronic period (after three weeks). In the acute group, two patients had Botsworth procedure and six had Weaver-Dunn operations. All six in the chronic group had Rockwood procedure. Nine patients achieved excellent outcome with full range of shoulder movement, pain free and return to work within three months of surgery. Two patients had good outcome. Three other patients had satisfactory outcome with tolerable pain and light duty at three months. Two patients developed chronic shoulder pain and one had painful hypertrophic surgical scar. Two patients had screw breakage requiring revision surgery. In conclusion, surgical treatment for ACJ dislocation produces good results. We suggest that surgical treatment be the treatment of choice for young patients requiring early recovery and good shoulder function.

We reviewed the incidence and treatment of flexor carpi radialis tendinitis in 77 patients (81 thumbs) who had trapeziectomy and abductor pollicis longus suspensionplasty for thumb carpometacarpal joint arthritis. Eighteen patients, 20 wrists (25%) had flexor carpi radialis tendinitis. The onset was 2-10 months (mean 4.7) after surgery. Two cases had preceding trauma. Eight cases (40%) responded to splinting and steroid injection. Ten patients, 12 wrists (60%) underwent surgery after failing non-operative treatment. Eleven wrists had frayed or partially torn flexor carpi radialis tendon and one had a complete tendon rupture with pseudotendon formation. Flexor carpi radialis tenotomy and pseudotendon excision were performed. All operated patients obtained good pain relief initially post-operatively. However, the pain recurred in two patients after 8 months. One required a local steroid injection for localized tenderness at the site of the proximal tendon stump. The other patient required a revision operation for scaphotrapezoid impingement. Both obtained complete pain relief. Our study has shown a high incidence of flexor carpi radialis tendinitis following trapeziectomy and abductor pollicis longus suspensionplasty. Patients should be warned about this potential complication.

Numerous studies have described various complications after endoprosthetic reconstructive operations. However, there are limited reports that focus specifically on deep infections (e.g., deep incisional surgical site infections), which remain one of the most dreaded complications of these operations, with rates ranging from 10% to 17%. Thus, this study was undertaken to determine the deep infection rates and to analyze possible risk factors, clinico-pathologic characteristics, and treatment modalities of endoprosthetic infections.
