Factors Affecting Postoperative Courses After Removal of Transphyseal Screws Inserted for Correction of Genu Valgum.

Background: The aim of this study was to investigate factors determining the final outcomes of hemipercutaneous epiphysiodesis using transphyseal screw (PETS) for the genu valgum, especially focusing on postoperative courses after screw removal.

Methods: Fifty-five patients with idiopathic genu valgum treated with hemi-PETS were included. The mechanical lateral distal femoral angle (mLDFA) and medial proximal tibial angle (MPTA) were measured to calculate the degree of correction and rebound.

Recurrence of a Unicameral Bone Cyst in the Femoral Diaphysis.

Diaphyseal unicameral bone cysts of the long bone are generally known to originate near the growth plate and migrate from the metaphysis to the diaphysis during skeletal growth. In the case of unicameral bone cysts of diaphyseal origin, recurrence at the same location is extremely rare. We report a case of recurrence of a unicameral bone cyst in the diaphysis of the femur that developed 8 years after treatment with curettage and bone grafting.

Outcomes of Combined Shelf Acetabuloplasty with Femoral Varus Osteotomy in Severe Legg-Calve-Perthes (LCP) Disease: Advanced Containment Method for Severe LCP Disease.

Background: Standard treatments may provide adequate containment in mild to moderate Legg-Calve-Perthes disease (LCPD), but they can be problematic in more severe cases. The purpose of this study was to report the results of combined shelf acetabuloplasty with femoral varus osteotomy in severe LCPD.

Methods: We reviewed 12 patients who had undergone combined shelf acetabuloplasty with femoral varus osteotomy.

Drop sign of the elbow joint after surgical stabilization of an unstable simple posterolateral dislocation: natural course and contributing factors.

Background: We performed this study to investigate the natural course and factors affecting the incidence of drop sign immediately after stabilization of an unstable posterolateral (PL) dislocation of the elbow.

Methods: Twenty-three patients who underwent a stabilization procedure for persistent instability after closed reduction of PL dislocation of the elbow were enrolled. The natural course was evaluated with simple radiographs taken at regular intervals after the operation.

Treatment of an 8-mm myxoma using acellular corneal tissue.

A myxoma is a benign tumor found in the heart and in various soft tissues; however, a corneal myxoma is rare. A mucinous mass of unknown etiology was observed on the left cornea of a 32-year-old male patient. We performed deep anterior lamellar keratoplasty using acellular corneal tissue and concurrent amniotic membrane transplantation.

Is sternocleidomastoid muscle release effective in adults with neglected congenital muscular torticollis?

Background: Neglected congenital muscular torticollis is rare in adults but may be associated with pain and cosmetic problems. The efficacy of surgical correction in these patients has not been well established in the literature.

Questions/purposes: We sought to describe (1) the primary goals that influenced adults with neglected muscular torticollis to seek surgical correction, (2) improvements of patients' function (specifically ROM) and radiographic parameters associated with deformities, (3) patient-derived outcomes using a previously published scale that includes function, and cosmesis, and (4) complications associated with sternocleidomastoid release in one surgeon's series of patients.

Severe equinus deformity after radiofrequency-induced calf muscle reduction.

Introduction: Radiofrequency-induced calf muscle volume reduction is a commonly used method for cosmetic shaping of the lower leg contour. Functional disabilities associated with the use of the radiofrequency (RF) technique, with this procedure targeting the normal gastrocnemius muscle, still have not been reported. However, the authors have experienced several severe ankle equinus cases after RF-induced calf muscle volume reduction.
