This case series aimed to describe a new technique for correcting contractures and deformities that reliably addresses lacrimal punctum deviation and severe cicatricial lower eyelid ectropion. This was a technical description and a retrospective interventional case series. Eyelid ectropion and lacrimal punctum deviation were treated surgically by grafting the fascia lata and suturing the tarsus-Horner muscle. In total, three patients underwent this surgery: one for burns, one for lower eyelid tumor resection, and the other for an orbital floor fracture following a motorcycle accident, all resulting in ectropion...

BACKGROUND: Ultrasound (US) has been suggested a valuable complement to clinical and radiological examinations in elbow trauma. Magnetic resonance imaging (MRI) has been the method of choice, despite fair to moderate interrater reliability (IRR). US has potential advantages but is assessor dependent and IRR scarcely examined. The primary aim of the present study was to investigate IRR for US and secondarily inter-observer agreement (IOA) between US and MRI in the acute phase after elbow trauma...

PURPOSE: To evaluate the clinical and structural outcomes of using injectable atelocollagen during arthroscopic rotator cuff repair (ARCR) for small to medium-sized rotator cuff tears. METHODS: This retrospective study reviewed patients with small to medium size full-thickness tears who underwent ARCR from 2016 to 2022 with minimum 1 year follow-up. Propensity score (PS) matching was used to reduce bias. Tendon integrity was evaluated using magnetic resonance imaging (MRI) at postoperative 6 months...

Disability due to iliopsoas (IP) pain and dysfunction is underdiagnosed in the athletic population. The IP unit consists of the psoas major and iliacus muscles converging to form the IP tendon and is responsible primarily for hip flexion strength but has a number of secondary contributions such as femoral movement, trunk rotation, core stabilization, and dynamic anterior stability to the hip joint. As the IP passes in front of the anterior acetabulum and labrum, the diagnosis of IP pain may be confused with labral tearing seen on magnetic resonance imaging...

OBJECTIVE: To investigate the effectiveness of one-hole split endoscope (OSE) technique in the treatment of single segment lumbar spinal stenosis (LSS). METHODS: The clinical data of 32 single segment LSS patients treated with OSE technique for simple spinal canal decompression between January 2022 and December 2022, who met the selection criteria, were retrospectively analysed. There were 18 males and 14 females, the age ranged from 45 to 82 years, with an average of 65...

BACKGROUND: The coactivation (Co-A) of shoulder muscles that contribute to humeral head depression can lead to mechanical unloading of the subacromial structures during abduction and thus can be beneficial for patients with arthroscopic rotator cuff repair (ARCR). The present study aims to examine the effectiveness of humeral head depressor muscle Co-A (DM-Co-A) training on clinical outcomes in a sample of patients with ARCR. HYPOTHESIS: We hypothesized that DM-Co-A training with medioinferior vector during glenohumeral exercises can improve clinical results in the rehabilitation of ARCR...

Superior capsular reconstruction (SCR) was developed to restore patient biomechanics for patients with massive irreparable rotator cuff repair (MIRCT) that precludes shoulder arthroplasty. Current studies have shown excellent short-term clinical outcomes and improved pain and functional scores, a high complication rate including re-tear, loss of fixation, or incomplete healing. An alternative, reverse total shoulder arthroplasty (rTSA) is a reliable and safe method to ensure good muscle strength and return to play in this patient group...

BACKGROUND: Percutaneous transvenous mitral commissurotomy (PTMC) is the first-line therapy of clinically significant rheumatic mitral stenosis. While the procedure is generally safe, new onset or aggravation of mitral regurgitation (MR) may occur, mainly due to commissural splitting and, less frequently, to leaflet tear and chordal rupture. Papillary muscle rupture (PMR) is exceedingly rare in this setting. CASE SUMMARY: A 74-year-old woman with a history of aortic valve replacement and prior rheumatic mitral commissurotomy presented for worsening exercise intolerance and exertional dyspnoea...

BACKGROUND: Superior capsular release has been used to reduce tendon tension, especially in arthroscopic repair of large-to-massive rotator cuff tears. Some clinicians have used a more extensive release of capsules in arthroscopic cuff repair for adequate reduction of torn tendons to footprints. PURPOSE: To explore the effects of additional posterior capsular release for superior capsular release in arthroscopic repair of large-to-massive rotator cuff tears. STUDY DESIGN: Cohort study; Level of evidence, 3...

BACKGROUND AND PURPOSE: Effective evaluation of rotator cuff tear residual tendon quality is the key to surgical repair. However, until now, the evaluation of rotator cuff tissue by ultrasonic shear wave elasticity (SWE) has been controversial. This prospective study analyzed the association between preoperative SWE and arthroscopic residual tendon quality scores. METHODS: The shear wave velocity (SWV) of the deltoid muscle, the supraspinatus tendon, and the supraspinatus muscle were measured in full-thickness rotator cuff tear patients...

Soccer participation is increasing among female adolescents with a concomitant rise of injuries in this group. Age- and sex-related factors, such as the transition from skeletal immaturity to skeletal maturity as well as anatomic, physiologic, neuromuscular, and behavioral differences between females and males, all play a role in injury patterns for these athletes. Anterior cruciate ligament (ACL) tears in this group have received a great deal of attention in the medical literature and the media in recent years with increasing knowledge about causative factors, surgical management, and injury prevention...

PURPOSE: This study aimed to compare the 5-year clinical and functional outcomes, including repaired tendon healing status, between early and delayed rehabilitation after arthroscopic rotator cuff repair METHODS: A total of 75 patients with rotator cuff tears (less than 5 cm) underwent arthroscopic repairs over a 60-month period. Participants were randomly assigned to early and delayed postoperative rehabilitation groups with distinct protocols. Clinical and functional outcome measures included Constant score, University of California at Los Angeles (UCLA) score, visual analogue scale for pain and isokinetic dynamometer test for muscle strength recovery...

To underscore the importance of evaluating the entrapment of the posterior femoral cutaneous nerve (PFCN) in patients exhibiting symptoms in the posterior thigh region. A 42-year-old male dentist, initially diagnosed with a semitendinosus muscle tear and persistent pain and tingling in the posterior thigh, sought treatment at our outpatient clinic. Despite unsuccessful physiotherapy, a comprehensive evaluation revealed an unusual entrapment of the PFCN between the sacrotuberous ligament and the semitendinosus muscle stump...

BACKGROUND: Muscle edema formation and inflammatory processes are early manifestations of acute rotator cuff lesions in sheep. Histological analysis of affected muscles revealed edema formation, inflammatory changes, and muscle tissue disruption in MRs. HYPOTHESIS: Edema contributes to inflammatory reactions and early muscle fiber degeneration before the onset of fatty infiltration. STUDY DESIGN: Controlled laboratory study. METHODS: Osteotomy of the greater tuberosity, including the insertion of the infraspinatus tendon, was performed on 14 sheep...

PURPOSE: To analyze the radiological features of the lacrimal gland (LG) and extraocular muscle (EOM) in thyroid eye disease (TED) patients with severe subjective dry eye disease (DED) using magnetic resonance imaging (MRI) measurements. METHODS: In this cross-sectional study, mechanical ocular exposure, dry eye assessment and MRI data were collected. Patients were classified into non-severe subjective DED group with ocular surface disease index (OSDI) < 33 and severe subjective DED group with OSDI ≥ 33...

Accurately diagnosing pectoralis major injuries, particularly in athletes, often presents a challenge for healthcare practitioners. Although pectoralis muscle injuries are relatively uncommon, the diagnosis of a tear may be overlooked without careful screening by a thorough physical examination of both the injured and uninjured sides. While magnetic resonance imaging (MRI) has traditionally held the gold standard, musculoskeletal ultrasound (MSKUS) has emerged as a viable alternative. This article delves into the power of MSKUS in evaluating and diagnosing pectoralis major injuries, highlighting its dynamic capabilities, real-time visualization, and cost-effectiveness in comparison to MRI...

PURPOSE: Irreparable rotator cuff tears are disabling and can severely affect daily life activities, especially when young and active patients are involved. The definition is still debated, and they can have several clinical presentations. The treatment depends on the clinical presentation and the patient's age. METHODS: The survey was developed by the ESSKA U45 Committee and was uploaded on the ESSKA website. Fifty-seven questionnaires were returned. Several aspects of the diagnosis and treatment of massive irreparable cuff tears were investigated...

BACKGROUND: Female athletes lag behind their male counterparts in recovery from anterior cruciate ligament (ACL) injury. Quadriceps muscle size and strength are crucial factors for regaining function after ACL injury, but little is known about how these metrics vary due to biological sex. HYPOTHESIS: Female patients have reduced vastus lateralis fiber cross-sectional area (CSA) and lower quadriceps strength after ACL injury than male patients. STUDY DESIGN: Cross-sectional study...

Knee osteoarthritis (OA) is a degenerative joint disease caused tearing and progressive wear of articular cartilage, and total knee arthroplasty (TKA) is recommended to patients with OA. The purpose of this study was to investigate the effect of proprioceptive neuromuscular facilitation (PNF) and both sides up ball (BOSU) exercises on pain, range of motion (ROM), and muscle function in patients following TKA. Ten participants who have limitation of the knee joint from TKA were divided into two groups: the continuous passive motion (CPM)+PNF exercise group (n=5) and the CPM+BOUS exercise group (n=5)...

PURPOSE: To investigate the correlation between rotator cuff stump classification and postoperative outcomes after superior capsular reconstruction (SCR). METHODS: A total of 75 patients who underwent SCR between June 2013 and May 2021 were included in this study. Based on stump classification using the signal intensity ratio of the tendon rupture site to the deltoid muscle in the coronal view of preoperative T2-weighted, fat-suppressed MRI scans, the patients were classified into types 1, 2, and 3 with ratios of < 0...
