Gigantic aneurysmal bone cyst of the scapula in children treated with left total scapulectomy and humeral suspension: A case report.

INTRODUCTION AND IMPORTANCE: Aneurysmal bone cyst (ABC) is a benign, rapidly growing, osteolytic and could have hemorrhagic lesion. This cyst mostly occurs in females under 20 years old and is located predominantly in the metaphysis of long bones, followed by the pelvis and spine. ABC of the scapula is a rare case, and their treatment still remains controversial. CASE PRESENTATION: A 7-year-old girl has had a growing lump on her left shoulder since two years ago. Physical examination revealed local tenderness and a firm and immobile mass, which limit shoulder motion. The radiological and histopathological results confirmed the diagnosis of ABC of the scapula. The patient underwent a left total scapulectomy and humeral suspension reconstruction and was augmented with surgical mesh. There were no signs of postoperative infection or recurrence during the 1-year follow-up. The MSTS score was 24. CLINICAL DISCUSSION: There are many options for ABC treatment. Resection of the cyst is the treatment of choice for aggressive tumors (Enneking stage 3) or lesions in less essential bones. In scapula, the ABC treatment with total scapulectomy followed by humeral suspension is an effective method to decrease complications and reduce the risk of recurrence with a good clinical outcome. CONCLUSION: ABC of the scapula is a rare case. Tumor resection for aggressive ABC should be considered to decrease the recurrence rate. Total scapulectomy with humeral suspension is an effective method for treating ABC scapula (Enneking stage 3).

Intratendinous ganglion cyst of extensor indicis propius tendon: A case report.

INTRODUCTION AND IMPORTANCE: The intratendinous ganglion cyst is an extremely rare entity. Thus, the global incidence has not been reported yet. The literature search showed scarce case reports and none has reported its occurrence in extensor indicis propius (EIP) tendon. The benign nature and the region at the dorsal hand mimic to the more common dorsal wrist ganglion. However, the surgical treatment arises significant risk to the function and may require subsequent tendon graft or tendon transfer. CASE PRESENTATION: A 51-year-old-female presented with 4 years history of a slow-growing lump over the dorsal region of the right hand with discomfort during finger motions. The ultrasonography confirmed the diagnosis of dorsal wrist ganglion. CLINICAL DISCUSSION: Intraoperatively, unlike the common presentation which is the well encapsulated mass originating from the carpal joint, the mass was found within the EIP tendon sheath and infiltrate the tendon substance. Surgical debulking was done and left the tendon partially intact. The frayed part was trimmed to ensure a smooth gliding. On the 6 month follow up, patient was symptom-free without any recurrence. CONCLUSION: The intratendinous growth of a ganglion must be identified preoperatively for a proper management plan and inform consent. The intratendinous ganglion cysts frequently weaken the tendon. Hence, surgical excision is necessary with the preparation of secondary tendon reconstruction.

Three-dimensional morphometric analysis of glenoid in the Indonesian population and its clinical significance.

Background: Understanding glenoid morphometry is important in shoulder prosthetic replacement surgery. In total and reverse shoulder arthroplasty, the size of the implants has to be determined according to the morphometry of the shoulder. However, there has been no known data on glenoid morphometry in the Indonesian population. Methods: Seventy-four computed tomography scans of asymptomatic shoulders were obtained from the medical databases of a third referral hospital in Jakarta. Mimics Research 21.0 was used to reconstruct 3D models of the scapula from the DICOM files. The morphometry parameters included were glenoid fossa height (GFH), maximum glenoid fossa width (MGW), glenoid width at center of the glenoid fossa (CGW), vertical distance between maximum width and center (VDMC), glenoid version angle (GVA), glenoid inclination (GI), glenopolar angle (GPA), glenoid vault depth (GVD), coracoid length (CL), coracoid midpoint length (CML), coracoid tip height (CTH) and width (CTW), and coracoid midpoint height (CMH) and width (CMW). Results: Our study found the average Indonesian GFH was 30.24 mm, the MGW was 24.03 mm, the CGW was 22.46 mm, the VDMC was 3.67 mm, the GPA was 42.76°, the GVD 18.8 mm, the GVA was 2.39° retroverted, the GI was 3.15° superiorly inclined, the CL was 37.76 mm, the CML was 18.89 mm, the CTW was 13.31 mm, the CTH was 8.52 mm, the CMW was 14.21 mm, and the CMH was 10.46 mm. All parameters except VDMC, GVA, and GI showed significant differences between male and female subjects Meanwhile, there was no significant difference in dimension and orientation of the glenoid and coracoid between the right and left shoulder. Conclusion: Our study showed a lower value of MGW, GFH, and GVD compared to other Asian ethnicities. These results may be helpful in designing smaller prostheses suitable for Indonesian glenoids.

Chronically unreduced elbow dislocation treated with box-loop ligament reconstruction: The first case series.

OBJECTIVES: Describing our initial experience of performing box-loop ligament reconstruction in patients with chronically unreduced elbow dislocation. DESIGN: Retrospective review. SETTING: One tertiary referral centre. PATIENTS/PARTICIPANTS: Six patients treated with box-loop ligament reconstruction from 2015 to 2018 were included in this study. INTERVENTION: Box-loop ligament reconstruction. MAIN OUTCOME MEASUREMENT: Quick disabilities of the arm, shoulder and hand (Q-DASH) and Mayo elbow performance index (MEPI) score. RESULTS: All subjects exhibited substantial increase of range of flexion-extension motion of the affected elbow, from a mean of 24.2° initially to 119.2° postoperatively during the follow-up period (median = 14 months, range 12-31 months). The subjects recorded an average MEPI score of 82.5 points, and average Q-DASH score of 16.2 points. There were no complications that occurred. CONCLUSIONS: This is the first case series of patients with chronically unreduced elbow dislocation treated with box-loop ligament reconstruction. Using this technique, all subjects had excellent outcome without any complication. Further studies with larger samples and better methodology are required to investigate the safety and efficacy of such technique.

Isolated coronoid fracture: Assessment by magnetic resonance imaging for concomitant injuries.

BACKGROUND: Ligamentous injury associated with isolated coronoid fracture had been sparingly reported. Concealed or unclear fractures and ligamentous or articular cartilage lesions are promptly acknowledged by magnetic resonance imaging (MRI) but cannot be entirely pictured in regular radiological assessments. In isolated coronoid fracture, the fragment size is very small and due to the complex anatomy surrounding the coronoid radiographic imaging may not be sufficient. The purpose of this study was to evaluate the incidence of combined osteochondral and ligamentous injuries by magnetic resonance imaging (MRI) in 24 patients with an isolated coronoid fracture. MATERIALS AND METHODS: In a retrospective study conducted at tertiary hospital between 2009 and 2011, elbow radiographs (anteroposterior and lateral views), computed tomography scan images, and MRI in the sagittal, coronal, axial, oblique, and coronal oblique planes were collected and reviewed. Musculoskeletal radiologist with subspecialty training in musculoskeletal MR interpretation and a fellowship-trained shoulder and elbow surgeon evaluated the MRI. RESULTS: The incidence of associated injuries revealed torn lateral collateral ligament (LCL) in all 24 patients (100%) while 15 patients (62.5%) had common extensor muscle tears. Seven of 24 elbows (29.2%) showed medial collateral ligament (MCL) tear, and 13 of 16 patients (81.3%) with anteromedial facet fracture had MCL attached to the fragment. Five of 24 (20.8%) cases had contusions on the radial head. On the distal humeral side, 15 patients had bone contusions on the posterior inferior of the trochlear on sagittal view. The ligament affections of the LCL were confirmed intraoperatively and repaired. CONCLUSION: LCL injury was consistent in all isolated coronoid fracture. The forces resulting in the injury appear similar to varus distraction forces acting in the knee leading to distraction injuries of the lateral structures of the knee joint. As concurrent osteochondral injuries and ligamentous injuries are not rare, magnetic resonance analysis serves as an excellent tool for analysis of the ligamentous injuries preoperatively and aids in surgical planning.

Surgical release of the first extensor compartment for refractory de Quervain's tenosynovitis: surgical findings and functional evaluation using DASH scores.

BACKGROUND: Few studies have evaluated surgical outcomes in patients with refractory de Quervain's disease using validated outcome measures. We assessed the clinical outcomes of dorsal release of the first extensor compartment for the treatment of de Quervain's disease using the disabilities of the arm, shoulder and hand (DASH) score. METHODS: From October 2003 to May 2009, we retrospectively evaluated 33 patients (3 men and 30 women) who underwent surgical treatment for de Quervain's disease. All patients had a positive Finkelstein test and localized tenderness over the first dorsal compartment. All operations were performed under local anesthesia. A 2-cm-long transverse skin incision was made over the first extensor compartment and the dorsal retinaculum covering the extensor pollicis brevis was incised longitudinally. Preoperative and postoperative clinical evaluation included the use of DASH score, Finkelstein test, and visual analogue scale (VAS) score. RESULTS: In 18 patients (55%), the extensor pollicis brevis tendon compartment was separated from the abductor pollicis longus compartment. Eight patients had intracompartmental ganglia in the extensor pollicis brevis subcompartment. All patients except one had negative sign on Finkelstein test at the last follow-up. The average VAS score decreased from 7.42 preoperatively to 1.33 postoperatively (p < 0.05), and DASH score was improved from 53.2 to 3.45 (p < 0.05). There were no postoperative complications such as subluxation of the tendon of the first dorsal compartment or injury to the sensory branch of the radial nerve. CONCLUSIONS: Intracompartment ganglia and the separate septum of extensor pollicis brevis are often related to de Quervain's disease. The release of the first extensor compartment for refractory de Quervain's disease resulted in good clinical outcomes with minimal morbidity.
