Performing a MOWHTO via the biplanar rather than the monoplanar technique allows larger-sized wedges to be opened with less risk of lateral cortical fracture. Thus, larger gaps can be opened and higher angle corrections can be achieved using the biplanar osteotomy procedure. From a clinical viewpoint, the biplanar osteotomy technique reduced the risk of lateral cortical hinge fracture during MOWHTO.
BACKGROUND: Supracondylar humerus fracture is the most common fracture of the elbow in children. Closed reduction and percutaneous pinning is considered to be the optimal treatment strategy; however, in some instances, open reduction may be necessary. The aim of this retrospective study was to compare clinical and functional results of triceps-splitting posterior versus lateral approach in pediatric supracondylar humerus fracture surgery.
Background:To evaluate the efficiency of the percutaneous 18-G needle technique in releasing the fibro-osseous sheath over the first dorsal extensor compartment of the hand.Methods:Using anatomic landmarks, percutaneous release was performed with an 18-G needle on 48 wrists of 24 cadavers. The specimens were then dissected and examined for the completeness of the first dorsal extensor compartment release and any tendon or neurovascular injuries. The tunnel length, number of abductor pollicis longus and extensor pollicis brevis tendons, presence of an intertendinous septum, and the effects of these parameters on percutaneous release were evaluated.Results:Percutaneous release was performed on all of the wrists, and the evaluation of the adequacy of release revealed 25 complete releases, 21 partial releases, and 2 missed releases. There were 19 cases of tendon complications. No neurovascular injuries were noted. The mean tunnel length was 2.66 ± 30 cm, and the mean number of tendons was 2.75 ± 0.86. A septum was present in 33.3% of cases. Tunnel length and tendon number had no statistically significant effect on release, whereas the presence of a septum was significantly associated with inadequate tunnel release and the development of tendon complications.Conclusions:Percutaneous release of the first dorsal extensor compartment using an 18-G needle was associated with high rates of incomplete release and tendon damage in the presence of an intertendinous septum. Further study is required under ultrasound guidance to determine the usefulness of percutaneous release in the first dorsal extensor compartment.Clinical Relevance:Release with a percutaneous needle tip in De Quervain’s syndrome may provide the advantages of better cosmetic results with less scar formation and an early return to work.
Background: Both the ilioinguinal and Stoppa approaches have been used as standard methods for treating anterior column fractures of the pelvis. Objective: We aimed to compare the rigidity of pelvises that were treated using these two approaches. Methods: Fifteen synthetic pelvises were used as test models. Of these, 5 pelvises did not undergo any treatment (control group), and 10 pelvises underwent treatment of one column using the ilioinguinal approach and the other using the medial Stoppa approach (treated group). The compression test was performed on all pelvises, and rigidity of the pelvises was compared between the control and treated groups. Results: A statistical difference was found in the angle between the center of the femoral head and the line from the pubic symphysis to load application between the control and treated groups, using the ilioinguinal approach. The parametric displacement was greater in the treated group using the ilioinguinal approach than in the control group. There were no significant differences between the control and treated groups using the Stoppa approach, and the ilioinguinal approaches. Conclusion: Clinically, the Stoppa approach has several advantages over the ilioinguinal approach. However, based on the compression test, there was no difference in biomechanical rigidity between the fixations performed using these two approaches.
A ganglion cyst (GC) is a mucinous or gelatinous-filled benign tumor overlying a joint or tendon sheath, which commonly arises in the dorsal and volar wrist side but may occur anywhere in the body. Although cystic lesions around the knee are common, the occurrence of GCs are rare. Ganglia may arise from intra or extra-articular, soft tissue, intraosseous, or periosteal location. Symptoms may vary according to the size and location. After the more frequent performance of magnetic resonance imaging for the assessment of a knee joint, the number of incidental, asymptomatic lesions have been increasingly diagnosed. The etiology of GC remains unclear; however, trauma and a flaw in the joint tissues may explain its appearance. The authors report two cases of women aged 47 years and 37 years who presented pain and swelling in their left knees following arthroscopic partial medial meniscectomy. The former was surgically treated and had a favorable outcome, while the latter had conservative treatment and a gloomy outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
