Study Characteristics Related to Citation Rates in Hip & Pelvis: An Analysis of Articles Published between 2009 and 2019 / 대한고관절학회지

Purpose@#We classified the articles published in the journal Hip & Pelvis and analyzed the relationship between study characteristics and citation rates. @*Materials and Methods@#All articles published in Hip & Pelvis from 2009 to 2019 were included. We classified the articles according to the type, language, listing in PubMed Central (PMC), treatment modality, material, design, anatomical focus, number of authors, and number of cases. We analyzed the citation rate according to this classification, with yearly citation rate reflecting the exposure period until March 2020. @*Results@#The yearly citation rate increased significantly after the language of the journal was changed from Korean to English in June 2014 (mean=0.96 vs. 1.63, P<0.05), and again after the journal was listed in PMC in March 2016 (mean=1.05 vs. 1.92, P<0.05). The yearly citation rates of review articles was highest, followed by those of editorials, original articles, and case reports (in this order). Among original articles, trauma-related articles had higher yearly citation rates than non-trauma-related articles (mean=1.00 vs. 0.68, P=0.034). Among clinical articles, studies focusing on the pelvis had higher yearly citation rates than studies on the hip or femur (mean=1.85 vs. 0.71 vs. 0.91, P=0.003). @*Conclusion@#The yearly citation rate of articles increased significantly after the language of Hip & Pelvis was changed to English and after the journal was listed in PMC. The mean yearly citation rate of articles focusing on the pelvis was significantly higher than that of articles focusing on the hip or femur.

Congenital Insensitivity to Pain with Anhidrosis: Five-Year-Old Girl with a Neglected Distal Femur Fracture / 대한정형외과학회잡지

Congenital insensitivity to pain with anhidrosis (CIPA) is a rare disease that affects the sensory and autonomic nervous system. The patients do not have the ability to sense different sensations, such as pain, which tends to lead to different injuries. In addition, the patients suffer from fluctuations in body temperature due to autonomic involvement. The present case was a five-year-old girl with a neglected distal femur fracture. X-rays taken during the follow-up showed marked callus formation and pseudarthrosis of the distal femur. She had biting injuries of the tongue, auto-amputation of the fingers, some developmental delay and a history of recurrent fever with an unknown origin. The electrodiagnostic study was normal. The quantitative sudomotor axon reflex test revealed markedly reduced postganglionic sudomotor axonal responses at all sites recorded on the left. She was diagnosed with CIPA. As the initial presentation of CIPA involves the musculoskeletal system, orthopedic surgeons should have a high index of suspicion.

Major Limb Replantation of Lower Leg Amputation with Ipsilateral Distal Femoral Comminuted Fracture in Old Age: A Case Report

The development of microsurgical techniques has also increased the success rate of replantation surgery. This paper reports the results of limb replantation performed on a lower extremity amputation that was associated with crush amputation and an ipsilateral comminuted fracture in and elderly patient. A 68-year-old female presented with a right distal tibia amputation due to a traffic accident. At that time, with a comminuted fracture in the distal femoral condyle, simple wound repair was recommended, but the caregivers strongly wanted replantation. Three years after surgery, normal walking was possible without a cane and the patient was satisfied with the function and aesthetics. What used to be contraindicated in limb replantation in the past are now indications due to the development of microsurgical techniques, surgical experience, and postoperative rehabilitation treatment. If the patient is willing to be treated, good results in contraindications can be obtained.

The Relationship between Early Improvement of Subjective Symptom and Surgical Outcomes in Moderate to Severe Cubital Tunnel Syndrome / 대한정형외과학회잡지

PURPOSE: Moderate to severe cubital tunnel syndrome usually requires surgical treatment. Most surgical outcomes are evaluated 6 months after the procedure; however, subjective symptoms begin to show improvement much earlier. In this study, we explored whether patients who experience early improvement of subjective symptoms have different clinical characteristics and surgical outcomes than those without early improvement. MATERIALS AND METHODS: Between January 2012 and February 2015, 36 surgical cases of moderate- to severe-stage cubital tunnel syndrome (modified McGowan grade IIA, IIB, or III) were included. Nineteen patients (15 males and 4 females with a mean age of 54.3±12.0 years) reported subjective symptom improvements within 14 days postoperatively. Seventeen patients (15 males and 2 females with a mean age of 53.4±11.9 years) did not report any early symptom improvements. Clinical characteristics—hand dominance, sex, smoking history, type of surgery, age, symptom duration, elbow range of motion, grip strength, key pinch strength, 2 point discrimination, pain, quick disabilities of the arm, shoulder and hand (DASH) score, and modified McGowan grade—were analyzed retrospectively using a Mann-Whitney test or chi square test. Surgical outcomes were measured at postoperative 3 and 12 months using repeated-measures ANOVA, and Wilson and Krout criteria were analyzed using a chi-square test. RESULTS: There was a difference in key pinch strength (p<0.001) between the groups. At postoperative 12 months, Wilson and Krout criteria (p=0.029) were associated with early improvement of subjective symptoms. The subjects' quick DASH scores and grip strengths improved over time, but no difference was observed between the groups. CONCLUSION: After surgical treatments of moderate to severe cubital tunnel syndrome, patients who presented early improvement of subjective symptoms, compared with those who did not, had significantly higher preoperative key pinch strength and better surgical outcomes at postoperative 12 months.

Recurrent Posterior Dislocation of the Elbow

The elbow joint is one of the most inherently stable articulations of the skeleton. Recurrent posterior dislocation of the elbow is a rare condition. We experienced a case of recurrent posterior dislocation of the elbow due to shallow trochlear notch and chronic radial head dislocation that was treated by transplantation of the biceps tendon to the coronoid process. We report on the case with a literature review.

Chronic Unreduced Elbow Dislocation Treated with Hinged External Fixator and Transarticular Pin Fixation / 대한정형외과학회잡지

Chronically unreduced elbow dislocation has commonly been described in underdeveloped countries. This is a very rare type of injury, and only two cases have been reported in Korea. Due to the potentially conflicting goals of restoring elbow stability and satisfactory function, successful treatment is a challenge even for experienced trauma surgeons. Herein, we described two cases of chronically unreduced elbow dislocation treated with open reduction and additional bony fixation using hinged external fixator and transarticular pin fixation.

Three Cases of Rare Anatomic Variations of the Long Head of Biceps Brachii

In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.

Postoperative Cubital Tunnel Syndrome due to Deep Flexor Pronator Aponeurosis / 대한정형외과학회잡지

Entrapment of the ulnar nerve around the elbow is the second most common compression neuropathy in the upper extremity. Many anatomical regions that possibly compress the ulnar nerve around the elbow joint have been described, however few cases below the flexor carpi ulnaris muscle have been reported. A case with ulnar nerve entrapment at the flexor pronator aponeurosis, secondary to surgery is reported in this study.

Palmar Fasciitis and Polyarthritis Syndrome Associated with Ovarian Carcinoma : A Case Report

Palmar fasciitis and polyarthritis syndrome (PFPAS) is an uncommon paraneoplastic syndrome characterized by rapidly progressive flexion contracture of both hands, inflammatory fasciitis, fibrosis and generalized inflammatory arthritis. We report a case of PFPAS associated with ovarian carcinoma, which was initially misdiagnosed as seronegative rheumatoid arthritis. A correct diagnosis was made after the patient underwent surgery for a pelvic tumor, which was incidentally found on a CT scan that she had taken after sustaining a traffic accident. PFPAS is one of differential diagnoses for progressive flexion contracture of both hands presenting to hand surgeons, and a careful oncologic examination should be considered in a female patient with unexplained hand pain, digital contracture and generalized arthritis

Factors for Recurrence in Pigmented Villonodular Synovitis of Large Joints / 대한정형외과학회잡지

PURPOSE: Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder of the synovium, and this can affect the joints, tendon sheaths or bursae. PVNS is histologically benign, but it has a high propensity for local recurrence. The purpose of this study is to identify the clinical and pathological factors that are associated with local recurrence of PVNS. MATERIALS AND METHODS: Fifty-one patients with biopsy-proven PVNS were retrospectively reviewed. There were 20 men and 31 women with an average age of 34 years (range: 12-73). The average follow-up period was 4.1 years (range: 1-25 years). All lesions were located in large joints (knee 25, ankle 11, hip 7, foot 5, wrist 2, elbow 1). Of the 51 lesions in the large joints, 39 were the diffuse type and 12 were the localized type. The initial clinical presentation was pain or a painful mass in 32 patients and a painless mass in 19 patients. Complete surgical removal of the lesion was performed in 39 cases, whereas incomplete excision was performed in 12. No adjuvant therapy was given in any cases. RESULTS: Sixteen local recurrences (31%) developed at an average of 24 months (range, 4-96). Factors related to local recurrence in the large joints were incomplete surgical removal (p < 0.001), diffuse type of the lesion (p=0.049) and the presence of bone erosion (p=0.037) CONCLUSION: In cases of PVNS in large joints, the factors that increased the local recurrence rate were incomplete surgical removal, diffuse type lesion and the presence of bone erosion.
