A common tumour at an uncommon location: Lesser trochanter osteochondroma

Osteochondromas are benign osteocartilaginous tumours, which are developmental abnormalities rather than actual neoplasms. The lesser trochanter is an extremely rare location for a solitary osteochondroma, and depending on the tumour’s size, the patient can exhibit various symptoms, including a limited range of motion. This case study describes a rare instance of a benign solitary osteochondroma of the lesser trochanter identified and managed using an excisional biopsy following Ludloff’s approach. With intraoperative fluoroscopy, we could accurately outline and remove the entire tumour mass without endangering the nearby essential tissues.

Extreme Serum Titanium Concentration Induced by Acetabular Cup Failure: Unveiling a Unique Scenario of Titanium Alloy Debris Accumulation.

The majority of contemporary total hip arthroplasty (THA) implants are constructed from Ti alloys, which are generally believed to generate fewer adverse local tissue reactions (ALTRs) compared to CoCr alloys. This study presents a case of unusual primary THA failure where a substantial release of Ti alloy debris was observed. A 52-year-old active male underwent THA after post-traumatic aseptic necrosis of the femoral head in 2006. Seventeen years after the procedure, the patient presented with groin pain and a restricted range of motion. X-rays revealed the protrusion of the alumina ceramic head through the Ti6Al4V acetabular cup. Trace element analysis indicated significantly elevated levels of serum Ti, Al, and V. CT and MRI confirmed Ti alloy cup failure and a severe ALTR. During revision surgery, it was found that the worn-out ceramic head was in direct contact with the acetabular cup, having protruded through a central hole it had created over time. No acetabular liner was found. Histological analysis of his tissue samples showed wear-induced synovitis with areas of multinucleated foreign body giant cells and the accumulation of numerous metal particles but no acute inflammatory response. Six months after the revision THA, the patient has experienced favourable outcomes. This case provides an instructive illustration for studying the consequences of the substantial release of Ti alloy debris from orthopedic implants.

Complex Case: Acute-on-Chronic Gouty Arthritis, Septic Arthritis, and Severe Joint Deformities in a Young Adult Patient

Background: Gout is the most prevalent type of inflammatory arthritis, which can lead to inflammation in the joints. However, septic arthritis is unusual in gout.
 Case presentation: A 34-year-old male presented with lumps on the right ankle with cloudy white fluid discharge for 5 days prior to admission. The patient also has lumps observed on the left pedis, and manus bilateral. The patient regularly takes Allopurinol daily and Piroxicam prior to admission. The physical examination had a limited range of movement. Laboratory examinations found elevated uric acid, impaired renal function, elevated white blood cells, and elevated erythrocyte sedimentation rate. The patient was then referred for surgical debridement.
 Conclusion: Chronic gout marked by persistent polyarticular engagement and the formation of tophi. In individuals left untreated, septic arthritis and gout may manifest, followed by deformities of joints, which need further diagnosis and management.

The epidemiological profile of temporomandibular joint disorders in the Tunisian population: A cross-sectional study

ObjectiveThis study aimed to explore the prevalence, signs, and symptoms of different types of TMD (Temporomandibular joint disorders) disorders in Tunisian patients. MethodsA retrospective cross-sectional study was conducted using the clinical records of patients from the Department of Functional Exploration, Pain, and Orofacial Dysfunction of the Dental Clinic of Monastir. ResultsTMD is associated with a female predominance, with a peak prevalence among those aged between 20 and 40 years. Pain and a limited range of motion were significantly more prevalent in women (p = 0.019 and p = 0.012, respectively). Clicking sounds were the most frequent joint noises (38.2 %). Crepitus was more prevalent among older adults (33 %). Of the different types of TMD, disk displacement with reduction was the most prevalent (n = 216, 39 %). Sleep bruxism was more prevalent than awake bruxism (20.7 % VS 9.5 %). Due to the heterogeneous TMD signs and symptoms, patients tend to seek medical attention from various specialties (e.g. neurology and otolaryngology). ConclusionThe prevalence of different types of TMD, and the different signs and symptoms varied depending on sociodemographic characteristics, such as sex, age and lifestyle. Diagnosis is challenging and TMD may be confused with other orofacial pain conditions.

Quantitative evaluation of adhesion severity around subscapularis and its relationship with shoulder range of motion in frozen shoulder and rotator cuff disorder: an observational study using dynamic ultrasonography

BackgroundThis study aimed to evaluate the severity of adhesion between muscles in the shoulder joint using dynamic ultrasonography and to confirm whether adhesions cause range of motion (ROM) restrictions. MethodsTwenty-four shoulders from fifteen frozen shoulder (FS) patients and Twenty-four shoulders from eighteen rotator cuff disorder (RCD) patients were enrolled. We obtained ultrasound video sequences of the subscapularis and deltoid muscles during shoulder external rotation. The mean stretching velocities of the deltoid (VDelt) and subscapularis (VSSC) were subsequently analyzed using a PC. If adhesions occurred between both muscles, the deltoid was stretched more vigorously, and we calculated VDelt/VSSC as adhesion severity. The coracohumeral ligament (CHL) thickness was measured using the same images. Shoulder ROM was measured by using a universal goniometer. ResultsThe intraclass correlation coefficients (1.1) and (2.1) of the adhesion severity measurements were 0.85 and 0.91, respectively. Multiple linear regression analysis revealed that the adhesion severity is a significant predictor for external rotation ROM in the RCD group (R2 = 0.44, F = 10.1, p < 0.01, t = -2.9), while CHL thickness predicts ROM in the FS group (R2 = 0.28, F = 5.5, p = 0.01, t = -3.0). ConclusionThe proposed method is reliable. Muscle adhesion causes ROM restriction of the shoulder joint. The primary cause of shoulder ROM restriction differed between the diagnostic groups.

Burden of routine orthopedic implant removal a single center retrospective study.

Open reduction and internal fixation represent prevalent orthopedic procedures, sparking ongoing discourse over whether to retain or remove asymptomatic implants. Achieving consensus on this matter is paramount for orthopedic surgeons. This study aims to quantify the impact of routine implant removal on patients and healthcare facilities. A retrospective analysis of implant removal cases from 2016 to 2022 at King Fahad Hospital of the University (KFHU) was conducted and subjected to statistical scrutiny. Among these cases, 44% necessitated hospitalization exceeding one day, while 56% required only a single day. Adults exhibited a 55% need for extended hospital stays, contrasting with 22.8% among the pediatric cohort. The complication rate was 6%, with all patients experiencing at least one complication. Notably, 34.1% required sick leave and 4.8% exceeded 14 d. General anesthesia was predominant (88%). Routine implant removal introduces unwarranted complications, particularly in adults, potentially prolonging hospitalization. This procedure strains hospital resources, tying up the operating room that could otherwise accommodate critical surgeries. Clearly defined institutional guidelines are imperative to regulate this practice. To measure the burden of routine implant removal on the patients and hospital. This is a retrospective analysis study of 167 routine implant removal cases treated at KFHU, a tertiary hospital in Saudi Arabia. Data were collected in the orthopedic department at KFHU from February 2016 to August 2022, which includes routine asymptomatic implant removal cases across all age categories. Nonroutine indications such as infection, pain, implant failure, malunion, nonunion, restricted range of motion, and prominent hardware were excluded. Patients who had external fixators removed or joints replaced were also excluded. Between February 2016 and August 2022, 360 implants were retrieved; however, only 167 of those who met the inclusion criteria were included in this study. The remaining implants were rejected due to exclusion criteria. Among the cases, 44% required more than one day in the hospital, whereas 56% required only one day. 55% of adults required more than one day of hospitalization, while 22.8% of pediatric patients required more than one day of inpatient care. The complication rate was 6%, with each patient experiencing at least one complication. Sick leave was required in 34.1% of cases, with 4.8% requiring more than 14 d. The most common type of anesthesia used in the surgeries was general anesthesia (88%), and the mean (SD) surgery duration was 77.1 (54.7) min. Routine implant removal causes unnecessary complications, prolongs hospital stays, depletes resources and monopolizing operating rooms that could serve more critical procedures.

Comprehensive Study on Musculoskeletal Injuries among Swimmers in Jordan: Causes, Effects, and Prevention Strategies

No prior investigations have evaluated the musculoskeletal (MSK) injuries characteristic of swimming sport in Jordan. This study aimed to identify the most common sports injuries among male and female swimmers in Jordan. Through a survey distributed to the Jordanian Swimming Federation’s registered swimmers, 173 participants (72 female, 101 male) aged 18 to 25 completed the questionnaire. The results of the study showed that the most common injuries were arranged as follows: muscle spasms, muscle cramps, and sprains; 29.8%, 28.6%, and 17.7%, respectively. The most vulnerable areas were the Shoulder 35.3%, followed by the back 14.4 %, the knee 10.7%, and the neck 10.2%. The most common cause of injuries was Inadequate warm-up, where his percentage reached 34%, followed by Overtraining with a percentage of 27%. Reduced training intensity or frequency, impaired stroke technique, limited range of motion or flexibility, and required complete cessation of swimming had the main effectiveness of the swimming performance and training, where the percent was 34.9%, 20.8%,10.3%, and 4.3%, respectively.

Detection of Rehabilitation Training Effect of Upper Limb Movement Disorder Based on MPL-CNN.

Stroke represents a medical emergency and can lead to the development of movement disorders such as abnormal muscle tone, limited range of motion, or abnormalities in coordination and balance. In order to help stroke patients recover as soon as possible, rehabilitation training methods employ various movement modes such as ordinary movements and joint reactions to induce active reactions in the limbs and gradually restore normal functions. Rehabilitation effect evaluation can help physicians understand the rehabilitation needs of different patients, determine effective treatment methods and strategies, and improve treatment efficiency. In order to achieve real-time and accuracy of action detection, this article uses Mediapipe's action detection algorithm and proposes a model based on MPL-CNN. Mediapipe can be used to identify key point features of the patient's upper limbs and simultaneously identify key point features of the hand. In order to detect the effect of rehabilitation training for upper limb movement disorders, LSTM and CNN are combined to form a new LSTM-CNN model, which is used to identify the action features of upper limb rehabilitation training extracted by Medipipe. The MPL-CNN model can effectively identify the accuracy of rehabilitation movements during upper limb rehabilitation training for stroke patients. In order to ensure the scientific validity and unified standards of rehabilitation training movements, this article employs the postures in the Fugl-Meyer Upper Limb Rehabilitation Training Functional Assessment Form (FMA) and establishes an FMA upper limb rehabilitation data set for experimental verification. Experimental results show that in each stage of the Fugl-Meyer upper limb rehabilitation training evaluation effect detection, the MPL-CNN-based method's recognition accuracy of upper limb rehabilitation training actions reached 95%. At the same time, the average accuracy rate of various upper limb rehabilitation training actions reaches 97.54%. This shows that the model is highly robust across different action categories and proves that the MPL-CNN model is an effective and feasible solution. This method based on MPL-CNN can provide a high-precision detection method for the evaluation of rehabilitation effects of upper limb movement disorders after stroke, helping clinicians in evaluating the patient's rehabilitation progress and adjusting the rehabilitation plan based on the evaluation results. This will help improve the personalization and precision of rehabilitation treatment and promote patient recovery.

Patient satisfaction after elective implant removal of the lower extremity — a retrospective cohort study

PurposeThe topic of elective implant removal (IR) in healed fractures of the lower extremity remains controversial, particularly when unspecific symptoms of discomfort, which cannot be quantified, are the primary indication. This study aims to assess indications and outcomes of elective IR of the lower extremity, focusing on unspecific symptoms of discomfort and patient satisfaction postoperatively.Materials and methodsThe retrospective cohort study was conducted at a single level I academic trauma center. We included patients who underwent elective IR for healed fractures of the ankle, foot, patella, and proximal tibia from 2016 to 2021. All patients were followed-up for a minimum of 6 weeks after IR. Our outcomes of interest were patient satisfaction, complications, and alleviation of complaints.Results A total of 167 patients were included in the study. Unspecific symptoms of discomfort were the most common reason for IR in all investigated anatomical regions of the lower extremity (47.9%), followed by pain (43.1%) and limited range of motion (4.2%). 4.8% of patients experienced a combination of pain and range of motion limitation. Among all patients, 47.9% reported subjective improvement after IR. IRs based on unspecific symptoms of discomfort were significantly less likely to show alleviation of complaints after IR (27.5%, OR 0.19, p ≤ 0.01). Patients who reported limited range of motion (OR 1.7, p = 0.41) or pain (OR 6.0, p = 0) were significantly more likely to be satisfied after IR. Patients who reported sensitivity to cold weather also showed a decrease of complaints after IR (OR 3.6, p = 0.03). Major complications occurred in 2.1% of cases. The minor complication rate was 8.4% (predominantly impaired wound healing). Smoking patients showed a significantly higher risk of complications after IR (OR 5.2, p = 0.006). Persistent pain postoperatively was detected in 14.7%.ConclusionWhen elective IR for consolidated fractures of the lower extremity is primarily motivated by patients’ subjective symptoms of discomfort, the risk for postoperative dissatisfaction significantly increases. Objective symptoms on the other hand are associated with higher satisfaction after IR. While the procedure is generally safe, minor complications such as wound healing disorders can occur, especially in smokers. Patient education and well-documented informed consent are critical.

Design of a novel low-speed gait rehabilitation device incorporating a synthesized geared five-bar mechanism

People with difficulty walking due to a stroke or neurophysiological gait deficit require gait rehabilitation. Recent research indicates that the optimal speed range for gait rehabilitation of such patients is less than 0.4 m/s. The design of a novel low-speed gait rehabilitation device based on a single degree of freedom (DOF) geared five-bar mechanism is presented in this paper. For this purpose, a natural gait meta-trajectory is generated using the recently acquired low-speed gait data suitable for human walking. A less-bulky single-DOF geared five-bar mechanism is synthesized and adjusted by applying the accurate and robust shadow robot control (SRC) synthesis method. Therefore, a practical and easily controlled gait rehabilitation device is designed, which can be mounted on any commercial treadmill and enables the patient to walk as close as possible to a normal gait. This device applies to a wide variety of individuals with different physiologies due to the mechanism’s adjustability, provided by the profile blending algorithm method. This method generates a set of continuous and speed-dependent gait trajectories for various individuals. The proposed device is inherently safe and easy to control due to the limited motion range of the single-DOF mechanisms and the use of a single actuator. Furthermore, because it only has two points of contact with the body (at the hip and the ankle), it takes less time for the user to don and doff.

Biomechanical Analysis Reveals Shoulder Instability With Bipolar Bone Loss Is Best Treated With Dynamic Anterior Stabilization for On-Track Lesions and With Remplissage for Off-Track Lesions

To compare the biomechanical effects of augmenting Bankart repair (BR) with either remplissage or dynamic anterior stabilization (DAS) in the treatment of anterior shoulder instability with on-track or off-track bipolar bone loss. Eight fresh-frozen cadaveric shoulders were tested at 60° of glenohumeral abduction in the intact, injury, and repair conditions. Injury conditions included 15% glenoid bone loss with an on-track or off-track Hill-Sachs lesion as previously recommended. Repair conditions included isolated BR, BR with remplissage, and BR with DAS (long head of biceps transfer). The glenohumeral stability was assessed by measuring the anterior translation under 0, 10, 20, 30, 40, 50 N load and maximum load without causing instability at mid-range (60°) and end-range (90°) external rotation (ER). Maximum range of motion (ROM) was measured by applying a 2.2-N·m torque in passive ER and internal rotation. Isolated BR failed to restore native glenohumeral stability in both on-track and off-track bipolar bone loss models. Both remplissage and DAS significantly decreased the anterior instability in the bipolar bone loss models, showing better restoration than the isolated BR. In the on-track lesions, DAS successfully restored native glenohumeral stability and mobility, whereas remplissage significantly decreased anterior translation without load (-2.12 ± 1.07 mm at 90° ER, P= .003; -1.98 ± 1.23 mm at 60° ER, P= .015). In the off-track lesions, remplissage restored native glenohumeral stability but led to significant ROM limitation (-8.6° ± 2.3° for internal rotation, P < .001; -13.9° ± 6.2° for ER, P= .003), whereas DAS failed to restore native stability at 90° ER regarding the increased anterior translation under 50 N (4.10 ± 1.53 mm, P < .001) and decreased maximum load (-13.8 ± 9.2 N, P= .021). At time-zero, both remplissage and DAS significantly reduced residual anterior instability compared with isolated BR in the bipolar bone loss models and restored the native glenohumeral stability under most translational loads. However, remplissage could decrease the anterior translation without load for on-track lesions and may restrict ROM for off-track lesions, whereas DAS failed to restore native stability under high translational loads for off-track lesions. DAS could be recommended to treat on-track bipolar bone loss with less biomechanical adverse effects, whereas remplissage might be the preferred procedure to address off-track bipolar bone loss for better stability.

An improved methodology to restrict the range of motion of mechanical joints

Joints with rotational degrees of freedom, for instance, revolute, spherical, or universal joints, are commonly utilized in real-world scenarios. In the multibody systems methodology, mechanical joints usually are formulated as classical kinematic constraints such that there is no restriction of the range of motion (RoM) of the joint. Thus, the formulation must include additional restrictions to prevent the joints from performing unacceptable movements and to avoid unrealistic configurations of the connected bodies. Therefore, the aim of this work is to propose a methodology to restrict the RoM of mechanical joints. Joint resistance moments are applied to the bodies connected by the joint to mimic the dissipative behavior of the materials constituent of joints and to prevent unacceptable configurations of those bodies. The proposed methodology aims to extend and improve a previously published study, specifically in the definition of the RoM limits, calculation of the penalty moments, and establishment of their direction of application. Enhanced methods to deal with the detection of unacceptable joint configurations, namely the elliptical and polynomial approaches, are proposed. A parametrization procedure is described to correctly calculate the direction of the penalty moments to apply to the connected bodies. The methodology is investigated in the dynamic modeling and simulation of one demonstrative example of application, namely a simple pendulum. A parametric analysis is performed to assess the influence of the methodology parameters in the response of the model. The methodology allows the correct restriction of the RoM of joints, while preserving the mechanical energy of the system.

A Nurse-Led App-Based Home Exercise Program After Total Knee Arthroplasty: A Quasi-Experimental Study.

Reduced activity because of pain is a major health issue associated with total knee arthroplasty. This study evaluated the effectiveness of a nurse-led app-based home exercise program for patients who underwent total knee arthroplasty. A nonequivalent control group of pretest-posttest design was used. Data from 45 patients were collected. The control group received individualized face-to-face exercise education, whereas the experimental group received training on the use of app-based home exercise education, including exercise videos and app push notifications to encourage exercise after discharge. Pain, range of motion, exercise self-efficacy, and quality of life were measured at baseline and 3 and 12 weeks after surgery. Nursing care satisfaction was evaluated 12 weeks after surgery. There were significant overall reductions in pain intensity ( p = .001), improvements in limited range of motion ( p < .001), and increases in exercise self-efficacy ( p = .034) and quality of life ( p = .033) in the experimental group ( n = 22) compared with those in the control group ( n = 23). Nursing care satisfaction was significantly higher in the experimental group than in the control group ( p < .001). Rehabilitation nurses can offer app-based home exercise education with push notifications to alleviate pain, enhance range of motion, improve exercise self-efficacy, and increase nursing care satisfaction for patients who have had a knee arthroplasty.

An Impressive Response to Zoldronic Acid Treatment for Chronic Recurrent Multifocal Osteomyelitis: A Case Report.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare, non-infectious inflammatory disease with a prevalence of 1 to 2/106, causing multiple lytic bone lesions. There are no established protocols for treating CRMO; thus, current practice is largely empirical. Data on the use of zoledronic acid (ZA) in juvenile CRMO are scarce. A 12-year-old male child with a history of multiple aseptic osteomylitis, affecting the chest wall, right ankle, and wrist, had no fever. Cultures and a bone biopsy ruled out infection or malignancy. The patient's condition stayed stable while taking naproxen (20 mg/kg/day) and methotrexate (10 mg/week) for 1.5 years until he experienced right elbow pain, swelling, no overlying skin erythema, and a restricted range of motion. The laboratory tests all came back normal, including white blood cell (WBC) count, erythrocyte sedimentation rate, C-reactive protein, and immunoglobin assays. The magnetic resonance imaging showed a focal lesion in the medial humeral condyle with increased signal intensity on T2 and short tau inversion recovery, mild joint effusion, and no cortical break. Thus, intravenous ZA infusion commenced at 0.0125 mg/kg initially, followed by 0.025 mg/kg 3 months later, with a marked improvement in the patient's clinical symptoms and radiological findings. Non-steroidal anti-inflammatory drugs and methotrexate were initially effective in treating our patient's condition, but a recurrence necessitated treatment modification. To the best of our knowledge, this case is the first documented instance of the use of ZA in CRMO in Iraq and Arab nations.

Association of Head-Neck Rotation With History of Pitching-Related Elbow Pain in Youth Baseball Players.

Prevention of pitching-related elbow pain in youth baseball players is important. Overhead pitching involves a whole-body motion, including head-neck rotation. A limited range of motion of head-neck rotation may cause inefficient pitching motion; however, this association is unclear. To determine whether the range of motion of head-neck rotation is associated with the history of pitching-related elbow pain in youth baseball players. Cross-sectional study; Level of evidence, 3. A total of 311 youth baseball players were selected and asked to complete a questionnaire survey about their age, weight, height, sex, baseball experience, main position, pitching side, and previous/current elbow pain during pitching. The range of motion of the upper and lower limb joints, head-neck rotation, and thoracic kyphosis angle were measured. Binomial logistic regression analysis was used to identify factors associated with the history of elbow pain related to pitching. There were 101 players with a history of pitching-related elbow pain (history group) and 142 players with no pitching-related elbow pain (no-history group). The history group had significantly lower values than the no-history group regarding the range of motion of head-neck rotation on the nondominant side (74.9°± 9° vs 77.7°± 9.6°; P = .02) and overall head-neck rotation (150.6°± 14.7° vs 154.9°± 18.4°; P = .04). Binomial logistic regression analysis identified head-neck rotation on the nondominant side (odds ratio [OR], 0.97 [95% CI, 0.94-1.00]), shoulder horizontal adduction on the dominant side (OR, 0.98 [95% CI, 0.96-1.00]), height (OR, 1.04 [95% CI, 1.00-1.08]), and playing position (pitcher) (OR, 0.40 [95% CI, 0.21-0.76]) as factors associated with a history of pitching-related elbow pain. Our cross-sectional analysis demonstrated that youth baseball players with a history of pitching-related elbow pain had limited head-neck rotation range of motion on the nondominant side, and this was a significant factor associated with the history of pitching-related elbow pain.

Treatment of osteochondral injuries of the humeral head using fresh osteochondral allograft transplantation

BackgroundLarge osteochondral lesions of the humeral head can result from locked posterior dislocations, avascular necrosis, and osteochondritis dissecans. Fresh osteochondral allograft (OCA) transplantation is a treatment option for young patients with focal osteochondral defects of the humeral head. The purpose of this case series was to assess graft survivorship, subjective patient-reported outcomes (PROMs), and satisfaction among seven patients who underwent OCA transplantation of the humeral head. MethodsWe identified seven patients who underwent humeral head OCA transplantation between 2008 and 2017. A custom questionnaire for patient reported outcome measures including ASES, QuickDASH, Likert satisfaction, and reoperations was mailed to each patient. Clinical failure was defined as further surgery that involved removal of the allograft. ResultsMedian follow-up duration was 10 years (range, 4.6 to 13.5 years) with a median age of 21.6 years (range, 18.5 to 43.5 years). Most patients (86%) reported improved function and reduced pain. At final follow-up, 71% of patients reported ongoing problems with their shoulder including pain, stiffness, clicking/grinding, limited range of motion, and instability. Return to recreational activities was high at 86% but 43% expressed limitations with activity due to their shoulder. Overall satisfaction was high at 71% with mean ASES and QuickDASH scores at 62.4 and 29.2 respectively. Reoperation after OCA occurred in one patient (14%). ConclusionsAmong this case series of seven patients who underwent OCA transplantation of the humeral head, patient satisfaction was high at 10 year follow-up and most returned to recreational activity although most also had persistent shoulder symptoms.

Efficacy of capacitive-resistive therapy on the treatment of myofascial pain – A randomized control trial

BackgroundMyofascial pain syndrome is a painful musculoskeletal condition with muscle spasm, referred pain, stiffness, restricted range of motion. Capacitive-resistive diathermy heats deep tissues by transferring energy through radiofrequency waves. Although this modality is used to treat various musculoskeletal disorders, there is no specific data on myofascial trigger points. Thus, we aimed to evaluate the effectiveness of capacitive-resistive diathermy on the myofascial trigger points. MethodsThirty-six volunteers with active myofascial trigger points were included. Patients were randomly and equally allocated into two groups. Group-1 is the capacitive-resistive diathermy treatment group; Group-2 is the placebo capacitive-resistive diathermy (PG). Visual analog scale (VAS), pain pressure threshold (PPT), neck disability index (NDI), neck range of motion (nROM), Short form-36 (SF-36) were used as outcomes before and after the intervention. ResultsIn both groups, VAS, PPT, NDI score significantly improved within the groups (p < 0.05). The CRG showed a statistically significant improvement in nROM for flexion, extension, and rotation (p < 0.05). However, ROM increase in CRG is not superior to PG (p > 0.05). ConclusionsThere was no significant difference between the two groups. We thought positive results in the PG might attributed to doing exercise. As a result, capacitive-resistive diathermy is not superior to exercise, but can be used as an adjuvant modality in myofascial trigger points treatment.

Perspective: Efficacy and outcomes for different lumbar interspinous devices (ISD) vs. open surgery to treat lumbar spinal stenosis (LSS).

Interspinous devices (ISD) constitute a minimally invasive (MI) alternative to open surgery (i.e., laminectomy/decompression with/without fusion (i.e., posterior lumbar interbody fusion (PLIF)/posterolateral instrumented fusion (PLF)) for treating lumbar spinal stenosis (LSS). Biomechanically, static and/or dynamic ISD "offload" pressure on the disc space, increase intervertebral foraminal/disc space heights, reverse/preserve lordosis, limit range of motion (ROM)/stabilize the surgical level, and reduce adjacent segment disease (ASD). Other benefits reported in the literature included; reduced operative time (OR Time), length of hospital stay (LOS), estimated blood loss (EBL), and improved outcomes (i.e., ODI (Oswestry Disability Index), VAS (Visual Analog Scale), and/or SF-36 (Short-Form 36)). Various studies documented the relative efficacy and outcomes of original (i.e., Wallis), current (i.e., X-STOP, Wallis, DIAM, Aperius PercLID), and new generation (i.e., Coflex, Superion Helifix, In-Space) ISD used to treat LSS vs. open surgery. Although ISD overall resulted in comparable or improved outcomes vs. open surgery, the newer generation ISD provided the greatest reductions in critical cost-saving parameters (i.e., OR time, LOS, and lower reoperation rates of 3.7% for Coflex vs. 11.1% for original/current ISD) vs. original/current ISD and open surgery. Further, the 5-year postoperative study showed the average cost of new generation Coflex ISD/decompressions was $15,182, or $11,681 lower than the average $26,863 amount for PLF. Patients undergoing new generation ISD for LSS exhibited comparable or better outcomes, but greater reductions in OR times, EBL, LOS, ROM, and ASD vs. those receiving original/current ISD or undergoing open surgery.

Clinical Outcomes After Arthroscopic Treatment of Extraspinal Diffuse Idiopathic Skeletal Hyperostosis (DISH) Involving the Hip Joint.

The hip joint can be affected by extraspinal diffuse idiopathic skeletal hyperostosis (DISH). This study aimed to compare the clinical characteristics of hips with DISH to those with mixed-type femoroacetabular impingement symptoms (FAIS). In addition, patient-reported outcome (PRO) scores were reported among patients with DISH involving the hip joint who underwent arthroscopic treatment. A retrospective analysis was performed using data from patients who underwent hip arthroscopy between 2017 and 2021. Patients who had a preoperative diagnosis of extraspinal DISH of the hip joint and postoperative Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sports Subscale (HOS-SSS), International Hip Outcome Tool 12-component form (iHOT-12), modified Harris Hip Score (mHHS) and visual analog scale (VAS) for pain scores were enrolled in the study. The patients' characteristics were compared with those of a control group (1:2) consisting of mixed-type patients with FAIS. The control group was matched in terms of age, sex, body mass index (BMI), and symptom duration. Eleven hips (0.87%) with extraspinal DISH (study group) were matched to 22 FAIS hips (control group). All the patients were male. The mean age of patients was 42.0 ± 8.0 in the study group. The study group was characterized by a larger preoperative alpha angle (79.1 ± 6.8 vs 64.8 ± 9.7, P < .001), lateral center-edge angle (LCEA) (49.7 ± 6.0 vs 40.7 ± 3.2, P < .001), and postoperative LCEA (36.6 ± 3.0 vs 34.2 ± 2.0, P = .013). In addition, a higher proportion of acetabular (81.8% vs 31.8%, P = .007) and femoral head chondral lesions (45.5% vs 9.1%, P = .016). Cartilage damage has the potential to affect the prognosis of arthroscopic treatment. Nevertheless, at the final follow-up, patients with DISH experienced a significant increase in range of motion (ROM), notable enhancements in all PROs, and favorable rates of minimal clinically important difference (MCID) for the PROs. The occurrence of DISH in the hip joint is considerably infrequent, characterized by hip pain and limited ROM. Despite increased alpha angle and LCEA, and more acetabular and femoral head chondral damage noted at the time hip arthroscopy, patients with DISH observed a significant improvement in ROM, notable enhancements in all PROs, and favorable rates of MCID for the PROs.

Reliability and Validity of the Variability Model Testing Procedure for Somatic Dysfunction Assessment: A Comparison with Gait Analysis Parameters in Healthy Subjects.

Somatic dysfunction (SD) is an altered body function involving the musculoskeletal system. However, its clinical signs-tissue texture abnormalities, positional asymmetry, restricted range of motion, and tissue tenderness-did not achieve satisfactory results for reliability. A recent theoretical model proposed a revision assessing the movement variability around the joint rest position. The asymmetry and restriction of motion may characterize functional assessment in osteopathic clinical practice, demonstrating the reliability required. Hence, this study investigated the reliability of the new variability model (VM) with gait analysis (GA). Three blind examiners tested 27 young healthy subjects for asymmetry of motion around rest position and the SD grade on six body regions. The results were compared to the VICON procedure for 3D-GA. The inter-rater agreement for the detection of reduced movement variability ranged from 0.78 to 0.54, whereas for SD, grade ranged from 0.64 to 0.47. VM had a sensitivity and specificity of 0.62 and 0.53, respectively, in SD detection compared to step length normality. Global severity grade of SD demonstrated moderate to good correlation with spatial-temporal parameters. The VM showed palpatory reliability and validity with spatial-temporal parameters in GA. Those findings contribute to the innovation for SD examination with implications for the clinical practice.
