Cross-cultural adaptation, validation and psychometric evaluation of the International Hip Outcome Tool 12 (iHOT12) to Hebrew.

BACKGROUND: The "International Hip Outcome Tool 12" (iHOT12) is a self-administered patient-reported outcome tool for measuring health-related quality of life and physical functioning in young and active patients with hip pathology. Since the iHOT12 has become widely used, we sought to translate and validate it for Hebrew-speaking populations. The aims of this study were: (1) To translate and culturally adapt the iHOT12 into Hebrew using established guidelines. (2) To test the new Hebrew version for validity, and (3) reliability. METHODS: The iHOT12 was translated and culturally adapted from English to Hebrew (iHOT12-H) according to the COSAMIN guidelines. For validity, the iHOT12-H and Western Ontario and McMaster universities osteoarthritis index (WOMAC) were completed by 200 patients with hip pathology. Exploratory factor analysis was used to assess structural validity. Subsequently, 51 patients repeated the iHOT12-H within a 2-week interval. Intraclass Correlation Coefficient (ICC), Cronbach alpha, and Standard Error of Measurement (SEM) were calculated to assess reliability. RESULTS: Construct validity: iHOT12-H correlated strongly to the WOMAC scores (r = -0.82, P < 0.001, Spearman). Factor analysis revealed a two-factor structure. Cronbach's alpha was 0.953 confirming internal consistency to be highly satisfactory. Test-retest correlation of the iHOT12-H was excellent with an ICC = 0.956 (95% CI 0.924-0.974). There was no floor or ceiling effect. CONCLUSION: The iHOT12 Hebrew version has excellent reliability, good construct validity and can be used as a measurement tool for physical functioning and quality of life in young, physically active patients with hip pathology. This study will serve Israeli researchers in evaluating treatment effectiveness for these patients. Moreover, it will also enable multinational cooperation in the study of hip pathology.

Lisfranc Injury Diagnosis: What Is the Diagnostic Reliability of New Radiographic Signs Using Three-dimensional CT?

BACKGROUND: Up to one-third of Lisfranc injuries (an injury affecting the normal stability, alignment, and congruency of the tarsometatarsal joints) are misdiagnosed. Delayed diagnosis and improper treatment may lead to long-term, irreversible sequela and functional disability. Recently, the employment of three-dimensional (3D) CT demonstrated higher diagnostic reliability, but there is limited evidence on this, and radiologic features of Lisfranc injuries when using this diagnostic modality are not well described. QUESTION/PURPOSE: What is the diagnostic performance of several novel radiographic signs on 3D CT when evaluating for Lisfranc injury, namely the Mercedes sign, the peeking metatarsal sign, and the peeking cuneiform sign, and what is the interobserver and intraobserver reliability of those diagnostic signs? METHODS: In this retrospective, diagnostic study, video clips of 3D CT reconstructions of 52 feet with intraoperatively confirmed Lisfranc injuries and 50 asymptomatic feet with a normal appearance of the tarsometatarsal joints, as ascertained by a subspecialty-trained foot and ankle surgeon and a musculoskeletal radiologist, were analyzed by two foot and ankle specialists and three orthopaedic residents twice each, with a washout period of 2 weeks. Among the 52 patients with intraoperative evidence of Lisfranc injury, there were 27 male patients and 25 female patients, with a median (IQR) age of 40 years (23 to 58); among the 50 controls, there were 36 male and 14 female patients, with a median age of 38 years (IQR 33 to 49). For each video clip, the presence of all three radiographic signs was documented (each sign was rated in a binary yes/no fashion). Before the evaluations, all observers underwent a short training session by the head of the foot and ankle department. Later, these reading were used to assess for the sensitivity, specificity, and area under the receiver operating characteristic curve in terms of Lisfranc diagnosis against the gold standard of intraoperative testing of tarsometatarsal joint stability. Intraoperatively, the congruency and stability of the second tarsometatarsal joint had been evaluated by direct visualization and by the insertion of a probe into the joint between the base of the second metatarsus and the medial cuneiform and twisting the probe to assess for stability. The individuals evaluating the video clips were unaware of the surgically obtained diagnosis at the time they performed their evaluations. RESULTS: All 3D radiographic signs that were examined had excellent diagnostic reliability in terms of sensitivity and specificity, ranging from 92% to 97% and from 92% to 93%, respectively. When assessing the association between the suggested 3D radiographic signs and Lisfranc injury diagnosis as a function of the area under the receiver operating characteristic curve, the Mercedes sign demonstrated a higher area under the curve than the other signs did (0.91 versus 0.87 versus 0.8; p < 0.001). The mean intraobserver and interobserver reliability (kappa) values were excellent for all 3D radiographic signs that were evaluated. CONCLUSION: The proposed radiographic findings demonstrated excellent diagnostic performance and were repeatable within and among observers. Three-dimensional CT radiographic signs could function as a valuable diagnostic tool for the evaluation and initial screening for Lisfranc injury in the acute injury phase because obtaining AP bilateral standing radiographs of the foot is often impractical in the acute setting. Further research and comparison with AP weightbearing radiographs of the bilateral feet may be warranted. LEVEL OF EVIDENCE: Level III, diagnostic study.

A Novel Classification for Diabetic Foot Ulcers of the First Ray.

OBJECTIVE: Diabetic foot ulcers of the first ray result from several distinct biomechanical mechanisms related to anatomical deformities, which must be addressed if surgical offloading is contemplated. The objective of this study was to create a classification of the anatomical deformities of first-ray ulcers that could lead to better standardization of treatment and reporting. METHODS: The authors performed a file review of patients with diabetic neuropathy diagnosed with first-ray ulcers over a period of 3 years in an outpatient setting. Anatomical deformities were diagnosed clinically and reported with ulcer location. The primary classification was the metatarsophalangeal joint, the interphalangeal joint, and the distal phalanx. RESULTS: Records for 59 patients (mean age, 62 years) with University of Texas A1 and A2 ulcers were reviewed. Mean ulcer duration was 2 months. The more common deformities were hallux valgus (41%), hallux valgus interphalangeus (14%), and hallux malleus (20%), and these were primarily associated with metatarsophalangeal, interphalangeal joint, and tip-of-toe ulcers, respectively (P < .0001). CONCLUSIONS: By classifying ulcer locations, the relevant corrective surgery may be chosen. Although some prophylactic procedures may be safe and effective, prophylactic hallux valgus correction in the diabetic foot requires further study.

Short-term Results and Return to Duty Following Hip Arthroscopy in Soldiers.

BACKGROUND: Over the past several years there has been a marked increase in the number of Israel Defense Forces (IDF) soldiers having hip arthroscopy based on magnetic resonance arthrography diagnosis of hip labral tears and/or impingement. OBJECTIVES: To detail characteristics of soldiers who underwent hip arthroscopy and assess outcomes and rate of return to duty. METHODS: A retrospective chart review was conducted of all soldiers who underwent hip arthroscopy 2018 to 2020, and soldiers referred for hip arthroscopy during 2021. Demographic, medical, and military service data were collected from the computerized patient record. RESULTS: Our study comprised 117 soldiers (29% combatants, 24% females) who underwent hip arthroscopy, mean age 22 ± 3 years, range 18-42; 45% had physiotherapy before surgery; 31% were diagnosed during or within 3 months of having back pain and 20% had been referred for psychological assistance (not related to the hip pain); 15.4% had serious adverse events. The mean time to return to any duty (including clerical work) was 8.0 ± 0.6 months; 56% of the soldiers never returned to service and were discharged from the military. During the one-year follow-up, only 6% returned to their full pre-symptom activity. CONCLUSIONS: The short-term results of IDF soldiers who underwent hip arthroscopy during the study period were much inferior to those reported among athletes. The lack of specificity of the diagnostic tools (history, examination, and imaging) used to determine whether surgery for hip pain is likely to be beneficial in this population may be contributing to over-diagnosis and over-treatment.

Lower Extremity Amputee Outcomes with Reference to Co-morbidities.

BACKGROUND: Lower extremity amputation related to diabetes is a serious outcome, which can have devastating effects on the patient and family. The epidemiology of amputations has recently been used as a possible measure of the adequacy of medical prevention and treatment of diabetes and diabetic foot complications. OBJECTIVES: To report on patients undergoing amputations at one medical center in Israel, their co-morbidities, and the outcomes. METHODS: A retrospective chart study was conducted of amputees operated between 1 September 2017 and 30 September 2018. RESULTS: The study population comprised 72 patients who had major amputations for diabetes and/or ischemia, mean age 72 ± 10 years, 74% males, 93% with type 2 diabetes. Mean age corrected Charlson Comorbidity Index was 8.2 ± 2.1 with 90% (65 patients) presenting with a score of 6 or higher. Before the recent deterioration, fewer than 20% of the patients exited their home routinely and 24% had an official diagnosis of dementia. There were 31 below knee amputations (BKA) and 41 above knee amputations (AKA). The 30-day, 3-month, 1-year, and 2-year mortality rates were 15.3%, 27.8%, 43.1%, and 54.2% respectively. Median survival period was 20 months. Survival after AKA was 13.4 ± 20, which was significantly less than after BKA (25.4 ± 2.7, P = 0.097). CONCLUSIONS: Factors other than the quality of management of patients with diabetes and complications may contribute to amputation rates; thus, making speculations from international comparisons of raw amputation rates problematic. This population was less healthy than reported in most studies.

The correlation between the ACR questionnaire and fitness for work of fibromyalgia patients.

OBJECTIVES: Fibromyalgia (FM) is a central pain syndrome characterised by widespread pain, fatigue, unrefreshing sleep, memory impairment and cognitive changes, predominantly in women, and is a cause for disability and frequent sick leave. So far, no assessment has been made of the use of the American College of Rheumatology (ACR) 2010 questionnaire in the fitness for work (FFW) assessment of FM patients. To assess the correlation between the severity of FM as measured by the ACR questionnaire and other parameters and FFW. METHODS: We conducted a retrospective cross-sectional study involving women with FM who had their FFW assessed at an occupational health clinic between 2014-2018. The ACR questionnaire was completed during the medical assessment. RESULTS: We examined 60 files of women, mean age 48.8 years. Absolute loss of working capacity (ALWC) was calculated in relation to a standard 8-hour workday, while relative loss of working capacity (RLWC) was based on the patient's actual appointment percentage before the examination. The average ALWC determined by the occupational physicians was 59% ± 33%. Age group correlated significantly with ALWC (correlation coefficient = 0.03, p<0.05). The Part 2b symptoms (0-41) also correlated significantly with ALWC (mean ± SD 21.8±5.6, correlation coefficient = 0.23, p<0.05). Medical treatment correlated significantly with RLWC (correlation coefficient = 0.02, p<0.05). The rate of disability was high compared to what was reported in other studies. The correlation between different parts of the ACR questionnaire and disability demonstrated that symptom severity is a predictor of loss of working capacity. CONCLUSIONS: When performing a FFW assessment of FM patients, physicians may use the ACR questionnaire, since FFW correlates with its score. We assume that patients who experience more pain visit their physicians more often and consume more analgesics.

Reliability of Trigger Point Evaluation in the Lower Leg Muscles.

BACKGROUND: Myofascial trigger point diagnosis is a clinical palpatory skill dependent on the patient's subjective response. The inter- and intra-rater reliability of trigger point physical evaluation in the lower leg muscles has rarely been reported. Previous reliability studies suffered from the Kappa paradox. OBJECTIVE: To evaluate the inter- and intra-rater reliability of trigger point recognition in the lower leg muscles implying a specific method to overcome the first Kappa paradox. DESIGN: A reliability study with pre-second examiner exclusion to correct prevalence index. SETTING: Physical therapy outpatient clinic, Beer-Sheva, Israel. SUBJECTS: In sum, 86 soldiers aged 18-30 referred for physical therapy with a diagnosis of musculoskeletal pain consented to take part in this study; 26 were excluded for lacking trigger points, leaving 60 subjects for analysis (31 women, 29 men). METHODS: Both legs were evaluated, and the results were analyzed separately for symptomatic (N = 87) and asymptomatic legs (N = 31). Each subject was evaluated three times, twice by one examiner, and once by a second examiner. Dichotomous findings including palpable taut-band, tenderness, referred pain, and relevance of referred pain were recorded. RESULTS: Inter-rater reliability for active trigger points ranged from 0.49 to 0.75 (median: 0.52) and intra-rater reliability ranged from 0.41 to 0.84 (median: 0.65) and. For total trigger points intra-rater reliability ranged from 0.52 to 0.79 (median: 0.67), and inter-rater reliability ranged from 0.44 to 0.77 (median: 0.66). CONCLUSIONS: Physical examination is a reliable method of trigger point evaluation in lower leg muscles, and it can be used as a diagnostic method for trigger point evaluation.

Occupational influences on Spondylolysis and Spondylolisthesis in a cohort of 18-year-old male military conscripts.

BACKGROUND: The reported prevalence of spondylolysis (SL) in the adult population is 6-7%. Data concerning adolescent-onset spondylolisthesis (SLS) and the impact of certain activities on it is scarce. We examined the risk of clinical progression of SL and SLS as a function of primary severity and occupational strain among military recruits. METHODS: Based on the Israel defense Force (IDF) central human resources database, we identified 1521 18-year-old males inducted to the IDF with SL/SLS between the late nineteen nineties and early two-thousands. We followed changes in the SL/SLS status during the 3 years of obligatory military service. Disease severity was classified as Cat2: radiological findings of SL without clinical findings; Cat3: painful SL or asymptomatic grade 1 SLS; Cat4: grade 1 SLS with pain; Cat5: Grade 2 SLS. The soldiers were subdivided into the following occupational categories: administrative, combat, maintenance, and driving. The purpose was to compare the progression rates in different medical categories and job assignments. RESULTS: There were 162 recruits in Cat2, 961 in Cat3, and 398 recruits in Cat4. The overall progression rate to Cat5 (grade 2 SLS) was 1.02%. Significant progression rates were seen amongst administrative soldiers with a relatively higher risk of progression from Cat4 (painful-grade-1 SLS: 2.2%) vs. Cat3 (asymptomatic SLS: 0.5%, relative risk = 4.7, p < 0.02). Other occupational categories did not exhibit significant progression rates. CONCLUSION: Progression of SL/SLS was highest in Cat4, i.e. for recruits already diagnosed with painful SLS (i.e. with a more severe baseline disorder). Progression did not correlate with military occupation. We recommend further follow-up studies that include, aside from progression rates, incidence rates of newly diagnosed grade 2 SL during military service.

The relationship between low back pain and professional driving in young military recruits.

BACKGROUND: Episodes of low back pain (LBP) are very common among workers. A number of occupational risk factors have been shown to increase the risk for LBP. One of these risk factors is exposure to whole body vibration, which is a known characteristic in driving professions. The aim of this study was to assess the impact of driving on LBP amongst young professional drivers. METHODS: This is an historical-prospective cohort study based on the Israel Defense Forces (IDF) database of male soldiers drafted between the years 1997-2006. Subjects' medical history with specific reference to LBP medical history, clinical and radiographic findings were taken as part of the recruitment process to the IDF. The study group included subjects (n = 80,599) from three occupational groups: administrative units (AU), car drivers (CD) and truck drivers (TD) that were followed for 3 years. The incidence and recrudescence rates of LBP were calculated based on standardized LBP severity tiers. RESULTS: The total incidence rate for LBP was 0.65%, 0.7% and 0.34% for AU, CD and TD respectively. In a comparison between subjects without a history of LBP (category 1) to subjects with a history of LBP without clinical findings (category 2) and subjects with a history of LBP with mild clinical / radiographic findings (category 3), the relative risk (RR) for severe LBP exacerbation was 1.4 (p < 0.001) and 3.8 (p < 0.01), respectively. The LBP exacerbation rates within different severity tiers yielded a similar trend amongst all profession groups. CONCLUSIONS: This study included 80,000 soldiers who represent a population of driving and administrative occupations aged 18-21. The significant risk factors for developing LBP were a previous history of LBP and presence of LBP symptoms at the start of work. A correlation was identified between severity of LBP at the initial examination and further exacerbation of LBP in all examined occupations. Driving as a profession in our (young) age-group was not identified as a risk factor for LBP.

Clinical Knee Alignment among Adolescents and Association with Body Mass Index: A Large Prevalence Study.

BACKGROUND: Children and adolescents are commonly referred to an orthopedic surgeon to assess knee malalignment. OBJECTIVES: To assess the prevalence of genu varum and valgum among adolescents, and to identify correlates of these conditions. METHODS: A medical database of 47,588 candidates for military service presenting to the northern recruitment center during an 11 year period was analyzed to identify clinical knee alignment. Based on the standing skin surface intercondylar distance (ICD) or intermalleolar distance (IMD), the prevalence rates of genu varum (ICD ≥ 3 cm) and genu valgum (IMD ≥ 4 cm) were calculated. The association of gender, body mass index (BMI), and place of residence to knee alignment was studied. RESULTS: The rates of genu varum and valgum were 11.4% (5427) and 5.6% (2639), respectively. Genu varum was significantly more prevalent among males than females (16.2% vs. 4.4%, P < 0.001). It was also more prevalent among underweight subjects and less prevalent among overweight and obese subjects (P < 0.001). Genu valgum was significantly more prevalent among females than males (9.4% vs. 2.9%) and in overweight and obese subjects compared to those with normal BMI, while less prevalent in underweight subjects (P < 0.001). Multivariate analysis revealed that genu varum was independently positively associated with male gender, underweight, and living in a rural area. Genu valgum was independently positively associated with female gender, overweight, and obesity. CONCLUSIONS: This study establishes a modern benchmark for the cutoff and prevalence of genu varum and valgum as well as associations with gender and BMI.

Outpatient Negative-Pressure Wound Therapy Following Surgical Debridement: Results and Complications.

OBJECTIVE: To present results and complications in a case series of outpatients with diabetic and neuropathic foot ulcers with exposed bone following surgical debridement treated with negative-pressure wound therapy (NPWT). METHODS: Retrospective data were obtained from digital medical records from the Maccabi Health Services High Risk Foot Clinic in Tel Aviv, Israel, between 2009 and 2014. Medical records examined were those of clinic outpatients with exposed bone following partial foot amputation or selective bone debridement (University of Texas grade III-A) treated with NPWT. MAIN OUTCOME MEASURES: Wound area, closure rate, and adverse events. MAIN RESULTS: There were 66 patients provided NPWT in a total of 77 treatment courses. Mean patient age was 62 ± 10 years, 82% were male, and mean diabetes mellitus duration was 14 ± 8 years. Mean HbA1C levels were 8.1% ± 1.7%. Mean treatment course duration was 16 days (range, 2-42 days). Wound area decreased significantly (from 11.3 ± 16.8 cm to 8.0 ± 13.3 cm, P < .0001). Ulcer curing was noted in 7% of the cases, and healing progression was noted in 54%. Seven serious adverse events were recorded. CONCLUSIONS: Outpatient NPWT is a relatively safe and effective adjuvant to surgical debridement of neuropathic foot ulcers. In an outpatient setting, one can expect serious adverse events to occur in 10% of cases, but this seems unavoidable in patients with diabetic foot ulcers when taking into account their comorbidities and patient resources. Strict protocols to promote early recognition of complications and appropriate response to minimize deterioration must be implemented.

Position Statement of the Israeli Society for Musculoskeletal Medicine on Intramuscular Stimulation for Myofascial Pain Syndrome-A Delphi Process.

OBJECTIVE: To develop consensus on a position paper on the use of intramuscular stimulation (IMS) for the treatment of myofascial pain syndrome (MPS) by physicians in Israel. METHODS: The Israeli Society of Musculoskeletal Medicine ran a modified Delphi process to gather opinions from a multidisciplinary expert panel. Eight experts in the treatment of MPS were chosen and asked to participate, and six participated. The position paper was iterated three times. RESULTS: After three iterations, general consensus was reached by all six experts. The general statement that was agreed on was: "IMS is one of the preferred treatments for myofascial pain syndrome. The treatment is evidence-based, effective, safe, and inexpensive. The position of the Israeli Society of Musculoskeletal Medicine is that the treatment should be taught and used by all primary care physicians and those physicians in other areas of medicine who deal with pain in their work." CONCLUSIONS: The position paper is a basis for clinical work and education programs for physicians interested in a better understanding and ability to treat patients with a musculoskeletal complaint or manifestation of disease.

The incidence and worsening of newly diagnosed low back pain in a population of young male military recruits.

BACKGROUND: Low back pain (LBP) is a leading cause of referral to occupational health clinics and of consequent work absenteeism. There is lack of data concerning ages 18-21. The objective of our study was to evaluate the occurrence of newly diagnosed LBP and the recurrence and worsening of preexisting LBP in young male military recruits. METHODS: In this retrospective cohort study, we examined the medical history of army recruits during the 30-month period after their induction into the Israel Defense Forces (IDF). The duty status of soldiers in combat units (CU), maintenance units (MU) and administrative units (AU) was evaluated according to their morbidity. The study's end point was defined as significant findings on clinical examination with presence of neurological deficits which correlate to radiological findings on CT or MRI showing herniated disks, spinal stenosis or pressure on neurological roots. RESULTS: The annual incidence rate of LBP in a total of 159,295 recruits was 0.05 %. The relative risk (RR) for developing LBP was significantly higher among subjects who were assigned to AU as compared to CU and MU in all LBP categories. The RR for LBP recurrence in soldiers with a positive history of LBP (categories 3 and 4) was 4.1 and 10.7 compare to category 1 respectively. CONCLUSIONS: The lower than expected overall incidence rate of 0.05 % reflects the fact that severe LBP occurrences are not common at this age group. This finding is a more truthful reflection of LBP occurrence rates relative to other studies since the end point is based on precise clinical definitions in medical records and not on questionnaires, as in most studies. The RR for developing LBP was significantly higher among subjects who were assigned to AU as compared to CU and MU in all LBP categories. Childhood history of LBP was found as a significant risk factor for LBP exacerbations at adulthood. Positive history of LBP was found as a risk factor for the recurrence of LBP in all occupation types and particularly in sedentary ones.

Telecommunications in Israeli field hospitals deployed to three crisis zones.

A field hospital overseas requires various types of communication equipment. This study presents the communications equipment used by three Israeli field hospital delegations to earthquake sites at Adapazari, Turkey, in 1999, Port-au-Prince, Haiti, in 2010 and Minamisanriku, Japan, in 2011. The delegations to Turkey and Haiti were relatively large (105-230 personnel) and were on the site early (three to four days after each event). The 55-person delegation to Japan arrived later and was established as an outpatient community hospital. Standard military VHF radios were the only effective tool up to 5 km, until cellular coverage was regained (1-2 weeks after each event). International communication was good. While short-wave communication (telephone and Internet) was used in Turkey, a direct satellite channel was set up in Haiti. In Japan, BGAN Inmarsat provided efficient Wi-Fi for all needs. Motorola walkie talkies were not efficient beyond the immediate vicinity. This paper recommends continued use of military-specification equipment alongside newer modalities, particularly in situations where infrastructure is damaged.

The supine apprehension test helps predict the risk of recurrent instability after a first-time anterior shoulder dislocation.

BACKGROUND: We previously identified the positive result of the supine apprehension test after completion of rehabilitation following a first dislocation as a possible predictor of high risk for redislocation. We extend the follow-up of a previous cohort of patients with first-time shoulder dislocations to better assess this test. METHODS: Fifty-three men aged 17 to 27 years who sustained a first traumatic shoulder dislocation were treated by shoulder immobilization for 4 weeks and then rehabilitated with a standard physical therapy protocol. At 6-week follow-up, a supine anterior apprehension test was performed to assess the risk of redislocation. The patients were observed prospectively for a minimum of 75 months. RESULTS: Of the 53 participants, 52 (mean age, 20.2 years) completed the study follow-up. Of the 52 subjects, 41 (79%) were combat soldiers. Follow-up was between 75 and 112 months. Of the 52 subjects, 31 (60%) redislocated at a range of 3 to 70 months after the initial dislocation. Eleven of 14 subjects (79%; confidence interval, 52%-92%) with a positive anterior apprehension test result redislocated, compared with 20 of 38 patients (53%; confidence interval, 37%-68%) with a negative test result. Patients with a positive test result redislocated more and earlier (P = .02, PROC LIFETEST, SAS). CONCLUSIONS: The results of the supine apprehension test after a first shoulder dislocation and rehabilitation can help predict risk for recurrent instability. It potentially may be included as a variable in decision analysis models.

Comparison of knee SPECT and MRI in evaluating meniscus injuries in soldiers.

BACKGROUND: Medical evaluation of a suspected meniscus injury begins with a history-taking and physical examination. Suspected meniscus injuries not responding to treatment are usually sent for imaging to confirm the diagnosis before arthroscopy. Tc-MDP bone single photon emission computed tomography (SPECT) scan has been suggested as an alternative to magnetic resonance imaging (MRI) in evaluating suspected knee meniscus tears. OBJECTIVES: To examine the accuracy of knee SPECT as a tool to identify meniscus tears versus that of MRI as compared to the gold standard of arthroscopy. METHODS: The Israel Defense Forces database for 2005 through 2009 was searched using the key words: knee MRI, knee SPECT and knee arthroscopy. We identified 330 subjects who had undergone both a single knee SPECT and a single knee MRI prior to knee surgery. The medical files of 193 of the 330 subjects were randomly selected for review. A comparison was made between the preoperative SPECT and MRI studies and the arthroscopic finding. The sensitivity, specificity and accuracy were calculated. RESULTS: The subjects' age was 21.3 ± 3.9. The agreement between SPECT and arthroscopy was 0.14 forthe medial meniscus and 0.29 for the lateral meniscus. The agreement between MRI and arthroscopy was 0.59 for the medial meniscus and 0.69 for the lateral meniscus. SPECT scan was found to be 61% sensitive, 54% specific and 58% accurate in detecting common knee pathology, whereas MRI was found to be 95% sensitive, 67% specific and 85% accurate. CONCLUSIONS: Knee SPECT has a lower sensitivity, specificity and accuracy than MRI in evaluating meniscal injuries and its use can result in increased unnecessary surgery.

At long-term follow-up many first-time male traumatic shoulder dislocators remain symptomatic.

OBJECTIVES: To assess the status at 13 to 17 years follow-up of a cohort of young male traumatic shoulder dislocators. STUDY DESIGN: Prospective cohort study. METHODS: A prospective study of first-time young male traumatic shoulder dislocators, began in 2004. Subjects were evaluated by the apprehension test after completing rehabilitation 6 to 9 weeks post dislocation. Between March 2021 and July 2022, a telephone questionnaire was administered to ascertain their current shoulder status. Subjects were questioned about avoidance of activities of daily living and sport, participation in sports, current instability, and self-assessed shoulder function by the SANE score. RESULTS: 50/53 (94.3%) of the study subjects, mean age 20.4 years, completed a mean follow-up of 181.8 ±â€¯12 months. The non-redislocation survival was 13% for those with a positive apprehension test and 49% for those with a negative test (p = 0.007). SANE scores were 64.3 ±â€¯23.7 for those with a positive apprehension test and 83.7 ±â€¯19.7 for those with a negative test (p = 0.001). In the year before the follow-up, 33.3% of those treated conservatively and 42.9% treated surgically experienced subluxation (p = 0.5). Fifty-seven percent of those who were treated conservatively and 56% of those who underwent surgery avoided some ADL or sports because of their shoulder. CONCLUSIONS: For young male first time traumatic shoulder dislocators a positive apprehension test after rehabilitation is associated with a high risk for reoccurrence and poorer long-term results. Most subjects were still dealing with shoulder symptoms at long-term follow-up.

Impact of an Enhanced Transtheoretical Model Intervention (ETMI) Workshop on the Attitudes and Beliefs Regarding Low Back Pain of Primary Care Physicians in the Israeli Navy.

Low back pain (LBP) is a major cause of discomfort and disability. Physicians' attitudes and beliefs influence the way patients with LBP are diagnosed and treated. The objective of the study is the assessment of military primary care physicians' attitudes towards LBP and the effect of an enhanced transtheoretical model intervention (ETMI) workshop on them. We evaluated the impact of a 90-min ETMI workshop on the attitudes and beliefs of primary care physicians in the Israeli Navy on LBP. Outcomes were assessed using the Attitudes to Back Pain Scale in Musculoskeletal Practitioners questionnaire (ABS-mp). Participants responded before and after the workshop, and responses were compared to a control group of primary care physicians in the Air and Space Force. The intervention group included 22 participants and the control group included 18 participants. Both groups were heterogenic (gender, age, seniority). In both groups, primary care physicians reported the common use of non-steroidal anti-inflammatory drugs (NSAIDs) and over-the-counter (OTC) pain medications and often included physical activity and physiotherapy in the treatment plan. Physicians mentioned reassurance and suggestions of early return to physical activity as part of their appointment. There was a positive correlation between questionnaire items suggesting the physician tended to a biomedical approach and reporting the use of imaging modalities (r = 0.451, p = 0.005). After attending the workshop, physicians were significantly more likely to recommend an early return to physical activity (18 ± 0.48 vs. 16.4 ± 0.52, p = 0.04). An ETMI workshop had a minor impact on the attitudes and beliefs of primary care physicians regarding LBP, but a statistically significant impact was noted on return to physical activity recommendations. These findings may be important in the military setting.

A simplified model to predict stress fracture in young elite combat recruits.

The purpose of the study was to develop a simple prediction model for stress fractures (SFs) in young male recruits to identify risk factors for SF. Data were collected from 57 young (18.5 ± 0.5 years) male athletes before elite combat basic training (BT). Measurements included anthropometric variables, blood samples, fitness tests, bone quality (peripheral quantitative computed tomography [pQCT]), psychological assessment, nutritional habits, and history of physical activity. A medical evaluation was done periodically. The SFs were clinically diagnosed during the 1-year training and thereafter confirmed by bone scintigraphy. Three "simple to monitor" variables were found to be significantly (p < 0.05) related to SF occurrence during basic and advanced training: aerobic training frequency, aerobic training duration, and waist circumference. From these 3 variables, a new model was constructed that successfully predicted 85% of the soldiers with (n = 23) and without (n = 34) SF as follows:(Equation is included in full-text article.)where PSF is the stress fracture prediction according to the Log Odds (SF), Odds(SF) is the ratio between the probability of SF existence and nonexistence, ATn is the aerobic training (times per week), ATt is the aerobic training duration (minutes per week), and waist is the circumference (centimeters). This model was validated on a different database taken from another 59 elite combat recruits before BT and successfully predicted 76.5% of the soldiers with SF (n = 22) and without SF (n = 37). A young male recruit for elite combat unit is at a greater risk of developing SF if, before entering BT, he trained aerobically <2 times per week with each training >40 minutes and has a waist circumference of <75 cm. However, further evaluation is required for different combat recruits, ages, and training programs to validate these results.
