Purpose To determine the association between femoral torsion and anterior cruciate ligament (ACL) rupture and determine the level of torsion using magnetic resonance imaging (MRI). Methods The medical records of patients who were diagnosed with ACL injury were reviewed retrospectively. This descriptive epidemiological study included 2344 patients. MRI scans were examined and patients with femur and knee MRI scans obtained at the same time were identified (ACL‐deficient group). Twenty‐eight of them had femur and knee MRI scans because of an incidental benign lesion in the distal femur. Patients who were diagnosed with enchondroma were followed up by MRI evaluation of the femur and were randomly selected as controls. Supratrochanteric torsion (STT), infratrochanteric torsion (ITT), and femoral anteversion (FA) were measured by orthopedic surgeons with at least 5 years of experience. Results Age, sex, and side properties were similar in both groups. The mean FA values were 19.4 ± 3.0 degrees and 11.9 ± 2.0 degrees in the ACL‐deficient and control groups, respectively (p < 0.001). STT was similar in the ACL‐deficient and control groups [mean: 38.2 ± 4.3 and 37.7 ± 3.3, respectively, (n.s.)]. ITT was increased in the ACL‐deficient group compared with the control group (mean − 18.8 ± 4.3 and − 25.8 ± 3.8, respectively; p < 0.001). Conclusions According to our results, increased FA was associated with ACL rupture. Further, the torsional abnormality was developed from the ITT. We concluded that each ACL‐deficient patient should be assessed by a clinician for torsional abnormality using physical examination. Level of evidence III

The aim of this study was to compare the midterm clinical and radiological outcomes of the Salter osteotomy (SO) and Tonnis lateral acetabuloplasty (TLA) with concomitant open reduction for the treatment of developmental dysplasia of the hip. Twenty-five hips of 20 patients who underwent SO with open reduction and 26 hips of 23 patients who underwent TLA with open reduction were evaluated retrospectively. The average age of the patients at the time of the operation was 35.6 months in the SO and 36.6 months in the TLA group, without a statistically significant difference (P=0.836). The average follow-up times in the SO and TLA groups were 59.9 and 54.8 months, respectively (P=0.397). Preoperative (40.6° in the SO vs. 42.2° in the TLA, P=0.451) and last follow-up acetabular index (12° in the SO vs. 14° in the TLA, P=0.227) and center-edge angle measurements (30° in the SO vs. 26° in the TLA, P=0.069) did not show a statistically significant difference between the SO and TLA groups; however, early postoperative acetabular index improvement was better in the TLA group than in the SO group (21.2° in the SO vs. 17.2° in the TLA, P=0.014). According to the Severin grading system, both groups showed a similar number of good outcomes without a statistically significant difference (P=0.936). Clinical assessment on the basis of McKay's criteria showed similar good and excellent outcomes (P=0.936). Both osteotomy techniques showed similar satisfactory outcomes for the treatment of DDH in patients older than 18 months of age.

Dysosteosclerosis is a group of sclerosing bone dysplasia characterized by short stature, increased bone fragility, osteosclerosis, and platyspondyly. It is a genetically heterogeneous disorder caused by biallelic mutations in the SLC29A3, TNFRSF11A, TCIRG1, and CSF1R genes. To date, four dysosteosclerosis patients with SLC29A3 mutations have been reported. Here, we report biallelic SLC29A3 (c.303_320dupCTACTTTGAGAGCTACCT) variant in a three‐year‐old girl. She had large anterior fontanelle, fracture history, short stature, camptodactyly, elbow contracture, and melanocytic nevus. Initial skeletal radiographs revealed platyspondyly, dense vertebral endplates (sandwich appearance of the vertebral bodies), diffuse sclerosis of the peripheral side of the pelvic bones, sclerosis of metaphysis and diaphysis of the long bones, metaphyseal widening, and diaphyseal cortical thickening. Mild sclerosis was also present in the skull base, maxilla, rib, scapula, and phalanges. Notably, we observed that sandwich vertebrae appearance significantly resolved and sclerosis of ribs, scapula, pelvis, and long bone metaphysis regressed over a 2.5‐year period. However, platyspondyly, metaphyseal widening, and diaphyseal cortical thickening persisted. In conclusion, this study demonstrates spontaneous resolution of osteosclerosis, which was not described previously in patients with dysosteosclerosis.

Background: Greater trochanter apophysiodesis (GTA) is relatively minimal invasive technique for the treatment of trochanteric overgrowth. Various types of implants can be used in each procedure. The purpose of this study was to compare outcomes of three different types of implants that were used in treatment of trochanteric overgrowth in Legg–Calve–Perthes disease. Materials and Methods: We retrospectively studied radiological results of three implants (screw, screw washer, and EP) on inhibiting trochanteric growth in 32 patients. Articulo-trochanteric and trochanter-trochanter distances (TTDs) were measured on radiographs. Embedding of implant evaluated on final radiographs. Results: The mean of age at the surgery was 10 ± 2.3 years, and the mean of follow up period was 50.0 ± 16.7 months. In all groups, articulo-trochanteric distance was decreased on final radiographs. In screw and screw washer group, increase of TTD was not statistically significant ( P < 0.05). Twelve, one, and two implants were embedded, respectively, in screw, screw washer, and EP groups. Two patients in EP group had revision surgery due to loosening. Conclusions: In this study group, GTA using screw and screw washer methods could slow down but did not restore trochanteric overgrowth. We suggest using washer to reduce embedding of the screw.

Objective: The aim of the present study was to evaluate the effectiveness of multilevel Botulinum Toxin A (BTX-A) injection, as part of an integrated approach, for the treatment of spasticity in non-ambulatory young children with diplegic cerebral palsy (CP). Subjects and Methods: Seventeen non-ambulatory patients aged 4–8 years with diplegic CP (Gross Motor Function Classification System [GMFCS] level IV) were evaluated before and at 1st, 3rd, and 6th months after BTX-A injection. The effect of BTX-A on spasticity of gastrocnemius and hamstring muscles was assessed using the Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS). The velocity-dependent properties of spastic muscle as both slow (R2) and fast (R1) stretches were evaluated in MTS. Results: A statistically significant improvement was observed in R1 angles of gastrocnemius and hamstring muscles at 1st and 3rd months after BTX-A injection in non-ambulatory young children with CP. Statistically significant improvement was found in MAS of gastrocnemius and hamstring muscles and R2 angles of knee and ankle joint after 1st month of BTX-A injection. Conclusion: Multilevel BTX-A injection, as part of an integrated approach, can be used for focal treatment of spasticity, especially of hamstring and gastrocnemius muscles, in non-ambulatory young children with CP GMFCS level IV.
