Accuracy of acetabular cup positioning using imageless navigation

Background: Correct placement of the acetabular cup is a crucial step in total hip replacement to achieve a satisfactory result and remains a challenge with free-hand techniques. Imageless navigation may provide a viable alternative to free-hand technique and improve placement significantly. The purpose of this project was to assess and validate intra-operative placement values for both inclination and anteversion as displayed by an imageless navigation system to post-operative measurement of cup position using high resolution CT scans

Medial gastrocnemius flap for reconstruction of the extensor mechanism of the knee following high-energy trauma. A minimum 5 year follow-up

The purpose of this study was to assess the medium-term results of reconstruction of the extensor mechanism using the medial gastrocnemius while also providing soft tissue coverage.This retrospective review consisted of a consecutive series of four patients (age 28-40 years) with complex high energy traumatic injuries to lower extremity including both soft tissue loss and disruption of the knee extensor mechanism. The medial gastrocnemius rotational flap was used to reconstruct the patellar tendon and restore soft tissue coverage simultaneously. Range of motion and extensor lag; functional recovery was judged by return to work and sports activity. Validated measures included the Oxford Knee Score, Knee Injury and Osteoarthritis Outcome Score, and the modified Cincinnati Score.At the final follow up was 61.5 (57-66) months after reconstruction, the mean SF 12 physical component score ranged from 21.7 to 56.8 with a median of 55.3; the mental component from 42.8 to 60.7 with a median of 58.6. The KSS knee score ranged from 50 to 78 with a median of 68; the function score from 65 to 90 with a median of 85. The Oxford knee score ranged from 22 to 45 with a median of 33.5. The KOOS ranged from 28 to 82.7 with a median of 73.7 and the modified Cincinnati score from 38 to 82 with a median of 76.5. Knee range of motion ranged from 0 to 120°. Of the four patients three returned to working fulltime in their profession and returned to sports, including mountain biking and fitness training.For severe traumatic knee injuries with the combination of soft tissue defects and disruption of the extensor mechanism, the medial gastrocnemius flap provides an excellent reconstructive option to address both problems simultaneously. The results of this small case series support the use of this limb salvage technique

Subacromial Decompression in Patients With Shoulder Impingement With an Intact Rotator Cuff: An Expert Consensus Statement Using the Modified Delphi Technique Comparing North American to European Shoulder Surgeons

Purpose: To perform a Delphi consensus for the treatment of patients with shoulder impingement with intact rotator cuff tendons, comparing North American with European shoulder surgeon preferences. Methods: Nineteen surgeons from North America (North American panel [NAP]) and 18 surgeons from Europe (European panel [EP]) agreed to participate and answered 10 open-ended questions in rounds 1 and 2. The results of the first 2 rounds were used to develop a Likert-style questionnaire for round 3. If agreement at round 3 was ≤60% for an item, the results were carried forward into round 4. For round 4, the panel members outside consensus (>60%, <80%) were contacted and asked to review their response. The level of agreement and consensus was defined as 80%. Results: There was agreement on the following items: impingement is a clinical diagnosis; a combination of clinical tests should be used; other pain generators must be excluded; radiographs must be part of the workup; magnetic resonance imaging is helpful; the first line of treatment should always be physiotherapy; a corticosteroid injection is helpful in reducing symptoms; indication for surgery is failure of nonoperative treatment for a minimum of 6 months. The NAP was likely to routinely prescribe nonsteroidal anti-inflammatory drugs (NAP 89%; EP 35%) and consider steroids for impingement (NAP 89%; EP 65%). Conclusions: Consensus was achieved for 16 of the 71 Likert items: impingement is a clinical diagnosis and a combination of clinical tests should be used. The first line of treatment should always be physiotherapy, and a corticosteroid injection can be helpful in reducing symptoms. The indication for surgery is failure of no-operative treatment for a minimum of 6 months. The panel also agreed that subacromial decompression is a good choice for shoulder impingement if there is evidence of mechanical impingement with pain not responding to nonsurgical measures. Level of evidence: Level V, expert opinion

Fellowship exit examination in orthopaedic surgery in the commonwealth countries of Australia, UK, South Africa and Canada. Are they comparable and equivalent? A perspective on the requirements for medical migration

International migration of healthcare professionals has increased substantially in recent decades. In order to practice medicine in the recipient country, International Medical Graduates (IMG) are required to fulfil the requirements of their new countries medical registration authorities. The purpose of this project was to compare the final fellowship exit examination in Orthopaedic Surgery for the UK, Australia, Canada and South Africa. The curriculum of the Australian Orthopaedic Association (SET) was selected as a baseline reference. The competencies and technical modules specified in the training syllabus, as well as the specifics of the final fellowship examination as outlined in SET, were then compared between countries. Of the nine competencies outlined in SET, the curricula of the UK, South Africa and Canada were all compatible with the Australian syllabus, and covered 97.7%, 86% and 93%, respectively, of all competencies and sub-items. The final fellowship examinations of Australia, South Africa and the UK were all highly similar in format and content. The examination in Canada was substantially different, and had two written sessions but combined the oral and clinical component into a structured OSCE using standardized patients and the component included unmanned stations. There were no significant differences for completion certificate of training and/or board certification observed between these countries. The results of this study strongly suggest that core and technical competencies outlined in the training and education curriculum and the final fellowship examination in Orthopaedic Surgery in Australia, South Africa and the UK are compatible. Between country reciprocal recognition of these fellowship examinations should not only be considered by the relevant Colleges, but should also be regulated by the individual countries health practitioner registration boards and governing bodies.http://tandfonline.com/loi/zmeo20hj2018Orthopaedic Surger

U-type bilateral sacral fracture with spino-pelvic dissociation caused by epileptic seizure

Sacral fracture with spino-pelvic dissociation is a rare and unstable injury caused by high-energy trauma, often with serious haemodynamic and neurological implications. Diagnosis is easily delayed or missed as it is often masked by severe associated injuries. Here, we present an unusual case of spino-pelvic dissociation sustained during a seizure episode in a young epileptic patient on long-term anticonvulsant therapy with previous thoracolumbar spinal arthrodesis. This unique case brings to light the need for clinicians to consider sacral fractures in patients presenting with low back pain with no preceding trauma who otherwise may have risk factors for pathological fractures

Anabolic steroids after total knee arthroplasty. A double blinded prospective pilot study

Background: Total knee arthroplasty is reported to improve the patient’s quality of life and mobility. However loss of mobility and pain prior to surgery often results in disuse atrophy of muscle. As a consequence the baseline functional state prior to surgery may result in poorer outcome “post surgery” and extended rehabilitation may be required. The use of anabolic steroids for performance enhancement and to influence muscle mass is well established. The positive effects of such treatment on bone and muscle could therefore be beneficial in the rehabilitation of elderly patients. The purpose of this study was to investigate the effects of small doses of Nandrolone decanoate on recovery and muscle strength after total knee replacement and to establish the safety of this drug in multimorbid patients. Methods: This study was designed as a prospective double blind randomized investigation. Five patients (treatment group) with a mean age of 66.2 (58-72), average BMI of 30.76 (24.3-35.3) received 50 mg nandrolone decanoate intramuscular bi-weekly for 6 months. The control group (five patients; mean age 65.2, range 59-72; average BMI 31.7, range 21.2-35.2) was injected with saline solution. “Pre-operatively” and “post-operatively” (6 weeks, 3,6,9 and 12 months) all patients were assessed using the knee society score (KSS), isokinetic strength testing and functional tests (a sit-to-stand and timed walking tests). In addition, a bone density scan was used preoperatively and 6 month postoperatively to assess bone mineral density. Results: Whilst the steroid group generally performed better than the placebo group for all of the functional tests, ANOVA failed to reveal any significant differences. The steroid group demonstrated higher levels of quadriceps muscle strength across the postoperative period which reached significance at 3 (p = 0.02), 6 (p = 0.01), and 12 months (p = 0.02). There was a significant difference for the KSS at 6 weeks (p = 0.02), 6 (p = 0.02) and 12 month (p = 0.01). The steroid group demonstrated a reduction in the amount of bone mineral density at both the femur and lumbar spine from “pre-” to “post-surgery”, however, these results did not reach significance (p < 0.05) using one-way ANOVA. Conclusions: This project strongly suggests that the use of anabolic steroids result in an improved outcome as assessed by the KSS and significantly increases extensor strength. No side effects were seen in either the study or control group.

The test-retest reliability of the Pieterse protocol return to flight assessment for cabin crew

INTRODUCTION: The purpose of this study was to assess test-retest reliability of the Pieterse return to flight duty protocol for cabin crew to return to flight duties. METHOD: Flight attendants between 20–50 yr old were included if they underwent rehabilitation at the musculoskeletal rehabilitation unit for a musculoskeletal injury, surgical treatment for orthopedic trauma or industrial injuries, and were assessed by the treating physical therapist and aviation medical examiner to be ready for return to work. Test-retest reliability was calculated with the Fleiss kappa coefficient. RESULTS: Included were 18 flight attendants (10 men, 34.9 ± 6.3 yr; 8 women, 34.2 ± 3.4 yr). Eight participants were rehabilitated following upper extremity injury, eight following lower extremity, and two following both upper and lower extremity injury. Perfect test-retest reliability was observed for nine items; kappa values above 0.9 were observed for three items; one item had a kappa value above 0.8 and two items had a kappa value of 0.78. The results for all 15 items were highly significant, demonstrating that the Fleiss kappa coefficients were significantly different from zero. The kappa coefficient strength of agreement was almost perfect for 13 and substantial for the remaining 3 items. Overall test-retest reliability was 0.95. DISCUSSION: This study demonstrated almost perfect test-retest reliability for 13 items and substantial reliability for two items, with an overall test-retest reliability of 0.95 for a return to flight assessment for flight attendants. The Pieterse protocol is a reliable tool to establish return to work for cabin crew.https://www.asma.org/journalhj2023Orthopaedic Surger

Functional and psychological outcomes of delayed lower limb amputation following failed lower limb reconstruction

The purpose of this study was to evaluate the functional and psychological outcomes of patients who underwent delayed lower limb amputation following failed limb salvage surgery.This retrospective, descriptive study evaluated functional outcomes using the Sickness Impact Profile (SIP) and Short Form-36 (SF-36) in 12 patients. Inclusion criteria included patients who underwent limb reconstruction and delayed amputation between July 2006 and December 2014, with an age range between 18 and 80 years of age, the ability to ambulate independently, a time interval between the last salvage procedure and amputation greater than six months, and a minimum follow-up of 24 months. Patients were contacted via telephone by the principal investigator and both the Sickness Impact Profile (SIP) and Short Form-36 (SF-36) were completed. Descriptive analysis (means and standard deviation) was used to determine outcomes for both SIP and SF-36 health profiles.Ten patients who had amputations following failed reconstruction (2006-2014) with a mean age of 53±10years were interviewed. Six patients had a SIP 10 points. The main deficit on the SF-36 was in the physical component. The SF-36 scores demonstrated a mean score of 40.8±11.5 for the physical component, and 57.4±7.9 for the mental component. Three patients returned to work after amputation and continued performing their pre-injury duties as farmers. Three other patients returned to work, but were allocated to administrative duties. Two patients were pensioners at the time of their injuries, and the only female patient was a housewife. One patient went into early retirement.The results of this study strongly suggest that delayed amputation following failed limb salvage surgery can still result in good and satisfactory outcomes in the majority of patients and achieves results similar to early amputation and limb reconstruction techniques

Single-stage osseointegrated reconstruction and rehabilitation of lower limb amputees: the Osseointegration Group of Australia Accelerated Protocol-2 (OGAAP-2) for a prospective cohort study

Introduction: Lower limb amputations have detrimental influences on the quality of life, function and body image of the affected patients. Following amputation, prolonged rehabilitation is required for patients to be fitted with traditional socket prostheses, and many patients experience symptomatic socket–residuum interface problems which lead to reduced prosthetic use and quality of life. Osseointegration has recently emerged as a novel approach for the reconstruction of amputated limbs, which overcomes many of the socket-related problems by directly attaching the prosthesis to the skeletal residuum. To date, the vast majority of osseointegration procedures worldwide have been performed in 2 stages, which require at least 4 months and up to 18 months for the completion of reconstruction and rehabilitation from the time of the initial surgery. The current prospective cohort study evaluates the safety and efficacy of a single-stage osseointegration procedure performed under the Osseointegration Group of Australia Accelerated Protocol-2 (OGAAP-2), which dramatically reduces the time of recovery to ∼3–6 weeks. Methods and analysis: The inclusion criteria for osseointegrated reconstruction under the OGAAP-2 procedure are age over 18 years, unilateral transfemoral amputation and experiencing problems or difficulties in using socket prostheses. All patients receive osseointegrated implants which are press-fitted into the residual bone. Functional and quality-of-life outcome measures are recorded preoperatively and at defined postoperative follow-up intervals up to 2 years. Postoperative adverse events are also recorded. The preoperative and postoperative values are compared for each outcome measure, and the benefits and harms of the single-stage OGAAP-2 procedure will be compared with the results obtained using a previously employed 2-stage procedure. Ethics and dissemination: This study has received ethics approval from the University of Notre Dame, Sydney, Australia (014153S). The study outcomes will be disseminated by publications in peer-reviewed academic journals and presentations at relevant clinical and orthopaedic conferences
