    ABSTRACT: Early surgical treatment is indicated to reduce mortality and morbidity associated with immobilization due to hip fracture. The judiciousness of postponing surgery to allow withdrawal of clopidogrel and return of normal platelet function (5-10 days) in elderly patients being chronically treated with this antiplatelet medication is a matter of ongoing controversy. The purpose of this study was to compare the morbidity and mortality rates in elderly patients receiving long-term treatment with clopidogrel who were operated on with or without delay (due to withdrawal of clopidogrel) following a hip fracture. We compared relevant demographic and medical/surgical parameters in patients receiving long-term treatment with clopidogrel who sustained a hip fracture and underwent either early (n = 30, mean ± SD age 81.6 ± 8.7 years, 17 males [57%]) or delayed (n = 30, mean ± SD age 83.3 ± 7.1 years, 13 males [43%]) surgical intervention between May 2007 and February 2010. Both groups were similar with regard to sex, age, co-morbidities and fracture type. The mortality rate was similar in both groups. Patients in the delayed treatment group had more complications associated with prolonged immobilization (pulmonary embolism, pulmonary oedema, decubitus ulcer). Time from admission to surgery and hospitalization stay were significantly longer in the delayed treatment group than in the early treatment group (mean ± SD 7 days and 12 hours ± 2 days and 17 hours compared with 1 day and 16 hours ± 1 day [p < 0.0001] and 17 days and 17 hours ± 7 days and 5 hours versus 11 days and 2 hours ± 4 days and 19 hours [p = 0.0002], respectively). Early surgical intervention for hip fracture in patients receiving long-term treatment with clopidogrel appears to be safe in terms of bleeding complications. It has the potential to enable earlier mobilization and shorter hospitalization and may reduce mortality and complications associated with immobilization.

    ABSTRACT: Idiopathic chondrolysis of the shoulder is an extremely rare condition. We report a unique case of glenohumeral joint chondrolysis which progressed rapidly, causing severe joint destruction. This catastrophic destructive process occurred within less than 1 month and resulted not only in the disappearance of the cartilage lining of the joint, but also in the destruction and deformation of the humeral head and some destruction of the glenoid. Clinical findings, radiographs, magnetic resonance imaging and nuclear scans are presented along with the histological findings, and a literature review.

    ABSTRACT: Scaphoid fracture is the most common fracture in carpal bone of the wrist and represents 11% of all upper extremity fractures. In most cases, the mechanism of injury is a fall with an outstretched hand. Scaphoid fracture detection can be made by clinical examination and standard radiography. Computed tomography (CT), bone scan and MRI improve the sensitivity of the diagnosis. Non-displaced fractures of the scaphoid are treated with cast immobilization in most cases. Operative treatment should be considered in displaced fractures or non-displaced fractures in young active patients by using internal fixation with cannulated screw for definitive anatomic and stable fixation. The main goals of operative treatment are attempts to reduce immobilization time and enable earlier return to work and activity. Displaced fractures of scaphoid, should be treated operatively, as they carry a greater risk for nonunion and malunion, which are associated with the development of radiocarpal arthritis, stiffness and wrist instability. Computed tomography is more useful as an assessment tool in pre-operative planning to determine the fracture location and fragment displacement. Early detection and appropriate treatment of scaphoid fractures is the key to favorable outcome in the treatment of scaphoid fractures.

    ABSTRACT: Fracture of the scaphoid is the most common fracture of a carpal bone. Nevertheless, the diagnosis of SF might be challenging. Plain X-rays that fail to demonstrate a fracture line while clinical findings suggest the existence of such a fracture is not uncommon. Currently there is no consensus in the literature as to how a clinically suspected SF should be diagnosed, immobilized and treated. To assess the current status of diagnosis and treatment of clinically suspected scaphoid fractures in Israeli emergency departments. We conducted a telephonic survey among orthopedic surgeons working in Israeli EDs as to their approach to the diagnosis and treatment of occult SF. A total of 42 orthopedic surgeons in 6 hospital EDs participated in the survey. They reported performing a mean of 2.45 +/- 0.85 clinical tests, with tenderness over the snuffbox area being the sign most commonly used. A mean of 4.38 +/- 0.76 X-ray views were ordered for patients with a clinically suspected SF. The most common combination included posterior-anterior, lateral, semipronated and semisupinated oblique views. All participating surgeons reported immobilizing the wrists of patients with occult fractures in a thumb spica cast based on their clinical findings. Upon discharge from the ED patients were advised to have another diagnostic examination as follows: 29 (69%) repeated X-rays series, 18 (43%) were referred to bone scintigraphy and 2 (5%) to computed tomography; none were referred to magnetic resonance imaging. No consensus was found among Israeli orthopedic surgeons working in EDs regarding the right algorithm for assessment of clinically suspected SF. There is a need for better guidelines to uniformly dictate the order and set of tests to be used in the assessment of occult fractures.

    ABSTRACT: Background: Transient osteoporosis of the hip (TOH) is a rare disease of unknown etiology, affecting middle-aged men, women in the third trimester of pregnancy, and rarely children, adolescents and nonpregnant women. Presenting symptoms are sudden hip pain and limp, initially with unremarkable radiographs and blood tests. Methods: Forty-eight patients (54 hips) with sudden hip pain were examined. All had radiographs, technetium bone scan and MRI. Increased uptake on bone scan and bone edema in the femoral head and neck on MRI were found in all patients. Five patients diagnosed with other disease processes were excluded from the study. The remaining (37 men, 6 nonpregnant women; 49 hips) were diagnosed with TOH. All had repeated clinical and MRI investigations until resolution of symptoms. Twenty-six patients had bone density measurements (DEXA) of both hips and spine. Mean follow-up was 43 months (range, 12–106 months). Results: Spontaneous resolution of symptoms occurred in all patients, and all were asymptomatic at final follow-up, although one patient had minor restriction of flexion. Despite the presence of crescent lines on initial MRI in 14 patients, none progressed to osteonecrosis, and crescent lines were not apparent on follow-up MRI. Excellent correlation was found between radiographic bone edema resolution and clinical improvement. DEXA measurements revealed nine men with abnormal bone density despite their relatively young ages. Conclusion: TOH is a benign disease, does not progress to osteonecrosis, and should be treated conservatively. Crescent lines may initially appear on MRI only to resolve spontaneously. Other diagnoses should be investigated if pain and bone edema persist.

    ABSTRACT: To assess the efficacy in providing improved function and pain relief by administering 8 weeks of acupuncture as adjunctive therapy to standard care in elderly patients with OA of the knee. This randomized, controlled, blinded trial was conducted on 55 patients with OA of the knee. Forty-one patients completed the study (26 females, 15 males, mean age ± SD 71.7 ± 8.6 years). Patients were randomly divided into an intervention group that received biweekly acupuncture treatment (n = 28) and a control group that received sham acupuncture (n = 27), both in addition to standard therapy, for example, NSAIDS, cyclooxygenase-2 inhibitors, acetaminophen, intra-articular hyaluronic acid and steroid injections. Primary outcomes measures were changes in the Knee Society Score (KSS) knee score and in KSS function and pain ratings at therapy onset, at 8 weeks (closure of study) and at 12 weeks (1 month after last treatment). Secondary outcomes were patient satisfaction and validity of sham acupuncture. There was significant improvement in all three scores in both groups after 8 and 12 weeks compared with baseline (P < .05). Significant differences between the intervention and control groups in the KSS knee score (P = .036) was apparent only after 12 weeks. Patient satisfaction was higher in the intervention group. Adjunctive acupuncture treatment seems to provide added improvement to standard care in elderly patients with OA of the knee. Future research should determine the optimal duration of acupuncture treatment in the context of OA.

    ABSTRACT: Interlocking intramedullary nails are the gold standard for treating tibial fractures. We compared the clinical and economic factors associated with tibial fracture fixation using either interlocking intramedullary or expandable nails. From 2000 to 2002, 53 patients with 53 diaphyseal tibial fractures of similar characteristics (AO/OTA 42A1-B3) were randomly and prospectively treated with either interlocking (n = 26) or expandable nails (n = 27). Patients were followed for a minimum of 2 years. The mean surgical duration was 104 minutes with interlocking nails and 52.9 minutes with expandable nails. Rehospitalizations were required in 12 patients (46%) and reoperations were required in nine patients (35%) with interlocking nails. Only one patient (3%) with an expandable nail required rehospitalization and reoperation. Union was achieved after 17 weeks (mean) with interlocking nails and 11.5 weeks with expandable nails. The beneficial economic ramifications of using expandable nails were a 39% reduction in overall surgical and hospital expenses. Expandable nails showed important clinical advantages for tibial fracture fixation, and complications related to lengthy operations, reoperations, and rehospitalizations were substantially reduced. Overall treatment cost was substantially lower with expandable nails. Based on these advantages, simplicity in use, and short surgical time, we recommend an expandable nail for treating tibial (AO Type A, B) shaft fractures.

    ABSTRACT: Carpal tunnel syndrome is the most common peripheral nerve compression syndrome. Compression of the median nerve in the carpal tunnel, disrupts the blood-nerve barrier causing edema, inflammation and fibrosis of its surrounding connective tissues. In the next stage of the syndrome there is a disruption of the myelin coverage of the nerve followed by damage to the axons. Most carpal tunnel syndromes are idiopathic. Other causes include intrinsic factors (which cause pressure within the tunnel), extrinsic factors (which cause pressure from outside the tunnel) and overuse/exertional factors. Patients usually report numbness and pain of the palmar aspect of their 1st, 2nd, 3rd and radial half of their 4th finger, night pain and gradual worsening of their symptoms. At a later stage, weakness and atrophy of the thenar muscles appears. The physical examination may show a decrease in sensibility, positive provocative tests and a decrease in thenar strength. The typical finding in the nerve conduction tests is a prolonged latency period. The conservative treatment for carpal tunnel syndrome includes ergonomic modifications, anti inflammatory medications and splintage and less frequently, special exercise and therapeutic ultrasound. The indications for operative treatment are failure of conservative treatment or severe carpal tunnel syndrome. The purpose of the operation is to relieve the pressure in the carpal tunnel by dissecting the transverse ligament. The operation can be done in an open approach, endoscopic approach or limited invasive approach.

    ABSTRACT: The WizAir-DVT is a miniature, lightweight (690 g), battery-operated and mobile intermittent pneumatic compression device (ICD), which enables continuous intraoperative use and immediate patient mobilization postoperatively. We compared its efficacy with a commonly used ICD, the Kendall SCD. Peak femoral vein flow velocity was measured in 20 apparently healthy volunteers at rest and with each device: we found no significant differences between them. A second prospective, randomized, clinical trial was used to compare the efficiency of the device in preventing deep venous thrombosis (DVT) after joint replacement in 50 patients (n=25/group). None developed DVT. Doppler ultrasonography revealed no significant differences. The WizAir-DVT antithrombotic compression device is as safe and effective as the Kendall SCD.
