Background@#Grip strength is important for fine motor skills, and one of the measurement tools for grip strength is the Martin Vigorimeter (MV) dynamometer. Studies on establishing the reliability and validity of the MV in Koreans are limited. We aimed to establish the reliability and validity of the MV for grip strength measurement in healthy Korean adults by comparing it with the Jamar dynamometer, the standard tool used by the American Society of Hand Therapists. @*Methods@#In total, 99 healthy participants (50 men and 49 women) were enrolled. Grip strength was measured using the Jamar dynamometer and MV. Reliability and validity were assessed using the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). The correlation between the measurements of the instruments was analyzed using Pearson’s correlation. The effect of hand anthropometry was evaluated, and the conversion equation between the instruments was calculated. @*Results@#MV showed excellent reliability (ICC > 0.90, p < 0.001) and validity with a high correlation (0.7 ≤ r < 0.9) with the Jamar dynamometer. The MDC was acceptable for detecting minimal clinically important differences (< 19.5%) in both instruments (Jamar:3.4%–6.7%, MV: 3.8% to 6.3%). The grip strength measured using the MV was independent of hand anthropometry, unlike that using the Jamar dynamometer. @*Conclusions@#This study provides insights into the relationship between the Jamar and MV instruments for measuring grip strength in Koreans. The MV is a viable alternative to the Jamar dynamometer in Koreans, offering not only reproducible and reliable measurements of grip strength but also the advantage of being unaffected by variations in hand anthropometry.

Purpose@#The purpose of this study was to retrospectively evaluate the effect of ‘Blocking Kirschner Wire (K-Wire) Technique’, which has been developed to reduce protrusion of the lateral wall, in maintaining the level of reduction through clinical and radiological outcomes. @*Materials and Methods@#Twenty-two patients with displaced intra-articular calcaneal fractures who used the blocking K-wire to maintain reduction (group A) and 44 patients that did not use blocking K-wire and were paired in 1:2 ratio with those Group A patients (group B), between January 2015 and December 2017 were enrolled in the study. All surgical procedures were performed via the extended sinus tarsi approach, and internal fixation using cannulated screws, Steinmann pins and K-wires was performed. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot scale and postoperative recovery of exercise ability were compared for postoperative clinical outcomes.The radiological results were compared the Böhler angle, Gissane angle, calcaneal height and width, step off of posterior calcaneal joint, and the degree of protrusion of the lateral wall. Moreover, postoperative complications in both groups were compared. @*Results@#There were no significant differences in the clinical outcomes of the two groups (p=0.924, p=0.961). The amount of Böhler angle, Gissane angle, calcaneal height and width, and step off of posterior calcaneal joint from the radiological results was not significantly different between the two groups (p=0.170, p=0.441, p=0.230, p=0.266, and p=0.400). However, the degree of protrusion of the lateral wall was 1.78 mm and 4.95 mm in group A and group B, respectively, and the difference between the two groups was significant (p=0.017). Although sural nerve entrapment and painful exostosis were more frequent in group B, they were occurred in a non-significant manner (p=0.293, p=0.655). @*Conclusion@#Most of the clinical and radiological results as well as the complications were not significantly different between the two groups. However, the degree of protrusion of the calcaneus lateral wall in group A was promising. The ‘Blocking K-Wires Technique’ established by the authors may be an effective surgical option for maintaining the reduction of the lateral wall protrusion in displaced intraarticular calcaneal fractures.

PURPOSE@#Although the number of hip arthroscopies is rapidly increasing in non-elderly patients, outcomes of this procedure in middle-aged patients are not well documented or clearly understood. The purpose of this study was to evaluate the clinical and radiological outcomes after hip arthroscopy in middle-aged patients with early osteoarthritis.@*MATERIALS AND METHODS@#This retrospective study analyzed 189 patients with early osteoarthritis of various diagnoses aged 40 years or older who underwent hip arthroscopy between January 2010 and December 2015. Clinical (e.g., modified Harris hip score [mHHS], hip outcome score-activities of daily living [HOS-ADL], visual analogue scale [VAS] for pain, range of motion) and radiological (change of Tönnis grade) outcomes were assessed at a minimum of 3-year follow-up.@*RESULTS@#The mean preoperative and final mHHS and HOS-ADL improved from 61.2 and 60.6 to 79.5 and 81.8, respectively, while the VAS pain score decreased from 6.3 to 3.2 (P<0.001). Although the mean range of internal rotation and flexion increased from 14.2 and 100.7° preoperatively to 30.4 and 110.6° at 1-year postoperatively, they decreased slightly to 27.4 and 105.4° at the final follow-up, respectively. Eight cases (4.2%) underwent revision arthroscopic surgery and three cases (1.6%) were converted to total hip arthroplasty.@*CONCLUSION@#Patients with early-stage osteoarthritis of various diagnoses achieved improved clinical outcomes. Therefore, using hip arthroscopy in middle-aged patients with early osteoarthritis, it is possible to achieve good surgical options.

PURPOSE@#This study evaluated the clinical and radiological results after reinforcement of the weakened medial joint capsule using Internal Brace (Arthrex) for treating severe hallux valgus.@*MATERIALS AND METHODS@#This study reviewed 56 cases of 50 patients that were followed-up postoperatively for at least 12 months, from September 2017 until August 2018. An extended distal chevron osteotomy combined with a distal soft-tissue release was performed by a single surgeon to treat severe hallux valgus. Internal Brace was applied in 12 cases (group A) who had weakened medial joint capsules, and capsulorrhaphy was performed in 44 cases (group B), and these two groups were compared postoperatively for the clinical and radiological results. The postoperative complications were also investigated.@*RESULTS@#No significant differences at 1-year follow-up on the Manchester-Oxford Foot Questionnaire and the patients' satisfaction scores were found between the two groups (p=0.905 and p=0.668, respectively). For the radiology, the changes of the values between before surgery and at 1-year follow-up according to the group showed no significant differences in the hallux valgus angle, intermetatarsal angle, and the hallux interphalangeal angle (p=0.986, p=0.516, p=0.754, respectively). Recurrence of hallux valgus was reported in two cases in group A, and in three cases in group B. Transfer metatarsalgia occurred in 4 cases in group B.@*CONCLUSION@#Based on these results, we recommend the capsule reinforcing technique using Internal Brace as a successful operative option for treating a weakened medial capsule in patients with severe hallux valgus.

A 48-year-old man visited the emergency room with right hip pain that started abruptly while walking out of the bathroom. Computed tomography showed an intraosseous mass in the femoral neck. The patient had a 15-year history of gout and had numerous bilateral tophi in his hands, feet, knees, and elbows. After operation, we diagnosed a pathological fracture due to intraosseous tophi. Patients with hip pain who have many subcutaneous tophi and long-standing gout should be diagnosed carefully. Peri-hip joint pain caused by gout is uncommon, however, if a patient complains of pain, a simple X-ray may be required. If intraosseous tophi are present, appropriate treatment (e.g., strict hyperuricemia control with or without prophylactic internal fixation), may be required before fracture occurs.

Stiff-person syndrome is a rare disorder, and the natural history of the syndrome has not been completely ascertained. The symptoms range from mild to severe and can progress over time: the final result can be significant disability. However, this syndrome is often misdiagnosed due to a lack of understanding of the clinical manifestations. We report the case of a patient who presented with slowly progressing gait disturbance and lower extremity pain and was later diagnosed as suffering from stiff-person syndrome. The patient experienced symptomatic improvement after the administration of benzodiazepines. No recurrence of symptoms has been reported. If the characteristic clinical features and electromyography findings of the syndrome are accurately interpreted, diagnosis of patients with abnormal muscle tension can be effectively done.

BACKGROUND: Patients with extraspinal diffuse idiopathic skeletal hyperostosis (DISH) involving the hip joint have symptoms like femoroacetabular impingement (FAI). To date, no reported study has determined the clinical outcomes of arthroscopic treatment in extraspinal DISH involving the hip joint. METHODS: A total of 421 hips with FAI that underwent arthroscopic treatment were reviewed retrospectively. We determined the extraspinal involvement of DISH with three-dimensional computed tomography (3D-CT) and simple radiography of the pelvis and hip joint. Clinical outcomes were evaluated at a minimum of 2 years postoperatively. The visual analog scale score (VAS), modified Harris hip score (MHHS), and hip outcome score–activity of daily living scale (HOS-ADL) were used, and hip range of motion (ROM) was evaluated pre- and postoperatively and at the time of the final follow-up. RESULTS: Among the 421 hips (372 patients) with FAI that underwent arthroscopic treatment, 17 hips (12 patients, 4.04%) had extraspinal DISH on the hip joints. The mean age of the patients was 51.5 years. The 3D-CT scans and simple radiographs showed extraspinal DISH on multiple points around the pelvis and hip joint. Nine of the 17 hips (seven of 12 patients) had spinal DISH. At the final follow-up, VAS, MHHS, and HOS-ADL improved significantly from 6.5, 65.3, and 66.6, respectively, to 1.2, 87.8, and 89.5, respectively, and hip flexion and internal rotation improved significantly from 97.7° and 7.9°, respectively, to 117.1° and 18.2°, respectively. CONCLUSIONS: This study has demonstrated that extraspinal DISH involving the hip joint could lead to FAI, and arthroscopic treatment could result in relief of symptoms, including pain and ROM limitation, in extraspinal DISH patients.

A three-year-old girl presented with a right-sided limp and mild fever. Laboratory findings were normal, except for an elevated erythrocyte sedimentation rate (ESR) of 30 mm/h and a C-reactive protein (CRP) level of 1.5 mg/dl. Magnetic resonance imaging showed a periosteal reaction in the distal posteromedial femur with contour bulging and extension of the reaction to the adjacent vastus muscles. Under a working diagnosis of acute suppurative osteomyelitis, she was initially treated with antibiotics and anti-inflammatory agents for one week. However, this did not result in resolution of her problems or normalization of the ESR and CRP. Biopsies of periosteum and muscle revealed Burkitt lymphoma expressing Bcl-6(+). In a child, limping can be the first clinical sign of hematogenous malignancy. In a limping child, if the general clinical course does not show improvement, and empirical treatment is ineffective, a comprehensive evaluation is necessary, including biopsies or bone marrow aspiration.

Apoptosis after global or focal cerebral ischemia plays a crucial role in mediating cell death. In this study, we observed the time point expression of physiologic events involving apoptosis regulatory proteins after photochemically-induced focal cerebral ischemia in Sprague-Dawley rats. Protein expression was evaluated at days 1, 3, and 7 by Western blot. Bcl-2, Bax, caspase-3, and phosphorylated Akt (pAkt) activity markedly increased in the ischemic hemisphere in a time-dependent manner, not affected. The expression of Bcl-2, Bax, and caspase-3 was dramatically changed around day 3, whereas changes in pAkt expression occurred at day 1. Differential elevation of these apoptosis regulatory proteins at various time points indicates that different modes of cell death occur in photochemically-induced focal cerebral ischemia in a rat brain.

Although a relatively large number of intracranial cavernous hemangioma have been reported, these vascular malformations in the extracerebral middle cranial fossa are rare. We experienced one case of extracerebral cavernous hemangioma in the middle cranial fossa. The patient was a 45-year-old female who had a visual impairment and intermittent seizure attack. We removed the mass partially because of profuse bleeding and confirmed cavernous hemangioma pathologically. And then irradiation was started after the operation. The mass responded to irradiation very well and the CT can showed significant reduction in the size of the mass and final disappearance. It is concluded that in case of an extracerebral cavernous hemangioma in the middle cranial fossa, irradiation was a very effective modality of treatment. At least the follow-up periods more than one year may be needed for the delayed effect of radiation therapy.
