Surgical treatment of slipped capital femoral epiphysis (SCFE) by Dunn procedure modified by Ganz: a systematic review.

BACKGROUND: Treatment of SCFE is still controversial, especially in moderate and severe forms. Dunn osteotomy performed with the Ganz approach became very popular in the last decade, although it is a complicated and challenging surgical procedure with a risk of AVN. The aim of our study was to analyze the current literature verifying the effectiveness of this surgical procedure, with specific attention to the incidence of AVN and other complications. MAIN BODY: A systematic review on the subject was performed according to the PRISMA guidelines. A literature search was performed by searching all published articles about the topic in the databases. The articles were screened for the presence of the following inclusion criteria: patients affected by slipped capital femoral epiphysis (SCFE) surgically treated by Dunn osteotomy using the Ganz surgical approach. All the patients affected by pathologies other than SCFE, treated without surgery or with procedures not including a surgical hip dislocation were excluded. Based on inclusion and exclusion criteria, 23 studies were included in our systematic review. Selected articles were published from 2009 to 2021 and they included 636 overall hips. According to the selected articles, Dunn osteotomy modified by Ganz, performed by an experienced surgeon, allows for anatomical reduction of moderate or severe SCFE with a low incidence of AVN. CONCLUSIONS: The few papers with long term follow-up, reported no progression of hip osteoarthritis, however, since the patients are adolescent at surgery, longer follow-up studies are needed to validate this statement. It is still debated if better results are obtained in stable or unstable SCFE. The indication of this procedure in mild SCFE remains controversial. LEVEL OF EVIDENCE: 3.

Surgical Treatment of Severe Idiopathic Flexible Flatfoot by Evans-Mosca Technique in Adolescent Patients: A Long-Term Follow-Up Study.

Flexible idiopathic flatfoot is very common in growing age and rarely causes pain or disability. Surgery is indicated only in severe symptomatic cases that are resistant to conservative treatment, and numerous surgical procedures have been proposed. Lateral column calcaneal lengthening as described by Evans and modified by Mosca is a widely used surgical technique for the correction of severe symptomatic flexible flatfoot. In the present study, we report the long-term clinical and radiographic results in 14 adolescent patients (mean age: 12.8 years) affected by severe symptomatic flexible flatfoot, surgically treated by Evans-Mosca procedure, for a total of 26 treated feet (12 cases bilateral and 2 unilateral). In all cases, surgery was indicated for the presence of significant symptoms resistant to nonsurgical management. Clinical evaluation was made according to the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale, the Foot and Ankle Disability Index (FADI) Score, and Yoo et al.'s criteria. Radiographic evaluation was made using anteroposterior and lateral weight-bearing radiographs of the feet to evaluate Meary's angle and Costa-Bertani's angle and to evaluate possible osteoarthritic changes in the midtarsal joints. At follow-up (mean: 7 years and 7 months), we observed a satisfactory result in all patients. The mean average score of the AOFAS Ankle-Hindfoot Scale improved from 60.03 points to 95.26; the mean FADI score improved from 71.41 to 97.44; and according to Yoo et al.'s criteria, the average clinical outcome score was 10.96. At radiographic examination, nonunion of the calcaneal osteotomy was never observed. Meary's angle improved from an average preoperative value of 25° to 1.38° at follow-up; Costa-Bertani's angle improved from an average preoperative value of 154.2° to 130.9° at follow-up. In no case, significant radiographic signs of midtarsal joint arthritis were observed. According to our results, we believe that Evans-Mosca technique is a valid option of surgical treatment for severe idiopathic flexible flatfoot and allows a satisfactory correction of the deformity with a low rate of complications.

Clear cell hidradenoma of the hand: A case report in an 83-year old patient.

INTRODUCTION: Clear cell hidradenoma (CCH) is a superficial adnexal tumor of the sweat glands. It generally appears on the trunk or scalp and is uncommon on the upper and lower limbs; it is extremely rare on the hand. CCH tend to be benign, with low malignancy risk. Treatment is based on complete surgical excision. We report a rare case of a CCH of the palm of the hand in an 83-year old patient. PRESENTATION OF CASE: An 83-year old male patient presented with a small mass on the palmar surface of his left hand, which was progressively increasing over 5 years. The tumor was surgically excised after sonography and sent for histologic examination, based on which diagnosis of CCH was made. Three months after surgery, the patient had no recurrence and was symptom free. DISCUSSION: CCH is a rare tumor of the distal extremities and to the best of our knowledge, only one case of this tumor on the hand has been reported. Our case represents a rare CCH located at the palm of the hand, which was successfully surgical excised without recurrence. Therefore, CCH needs to be considered in the differential diagnosis when encountering masses on the distal extremities. Hidradenocarcinoma is the malignant variant that arises from the same cells. CONCLUSION: We report the second case of CCH on the palmar surface of the hand. Treatment of choice is surgical excision, followed by histological analysis and close follow-up for recurrence.

Surgical treatment of primary trapezio-metacarpal osteoarthritis by trapeziectomy and ligament reconstruction without tendon interposition. Long-term results of 50 cases.

BACKGROUND: Primary trapezio-metacarpal osteoarthritis can be painful and disabling. Surgical treatment is used when conservative treatment, such as splinting or oral analgesics, fails. The purpose of this study was to report the long-term outcomes obtained in 40 patients (50 thumbs) surgically treated for thumb osteoarthritis by trapeziectomy and ligament reconstruction without tendon interposition. MATERIALS AND METHODS: Forty patients (50 thumbs), with severe trapezio-metacarpal osteoarthritis, surgically treated by trapeziectomy and ligament reconstruction without tendon interposition were reviewed after an average follow-up of 8 years. All patients were women. At follow-up, clinical results were evaluated on the basis of the DASH score, possible presence of pain and the following criteria: palmar abduction of the thumb, carpometacarpal joint opposition of the thumb (Kapandji), extension of the metacarpophalangeal joint and strength of the hand. RESULTS: The DASH score improved from 42.65 (preoperatively) to 16 (at follow-up), and most patients were asymptomatic. Palmar abduction of the thumb averaged 57 mm. Carpometacarpal joint opposition averaged 8.8. Metacarpophalangeal extension was abnormally increased in 86% of the cases. The strength of the operated hand was comparable to the contralateral side in 46 cases. Radiographic examinations showed a slight proximal migration of the first metacarpal bone (< 3 mm) in all cases but mild signs of carpometacarpal osteoarthritis in only 4 cases. CONCLUSIONS: Based on the reported experience, we believe that primary trapezio-metacarpal osteoarthritis surgically treated by trapeziectomy and ligament reconstruction without tendon interposition allows good long-term results. LEVEL OF EVIDENCE: Therapeutic IV.
