Pediatric infrafossal fracture of the humerus: A case series.

OBJECTIVES: In this case series, we aimed to evaluate the clinical and radiographic outcomes of the patients with infrafossal fracture of the humerus and to evaluate the upper extremity and elbow function with the Mayo Elbow Performance Score (MEPS) and Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. PATIENTS AND METHODS: Between January 2005 and July 2020, the clinical data and radiographs of 2,443 children who were treated due to distal humerus fracture were retrospectively analyzed. A total of six patients (5 males, 1 female; mean age: 6.7±2.6 years, range, 3 to 11 years) treated due to an infrafossal fracture of the humerus were included. Radiographic measurements, such as Baumann's angle, lateral capitellohumeral angle, and carrying angle of the elbow, were performed. At the final follow-up, elbow joint range of motion (ROM) was measured, functional scores of the elbow and upper extremity were assessed. Complications were also recorded. RESULTS: The mean follow-up was 62.8±47.4 (range, 20 to 140) months. Two patients underwent open and three underwent closed reduction and internal fixation by different surgeons. One of the patients was treated with a long-arm cast. There was no major elbow ROM limitation. There was no significant deterioration in the lateral capitellohumeral and elbow carrying angles of the patients. Baumann's angle was normal for all the patients; however, it could not be measured in two patients, as their epiphyses were closed. Four patients had an excellent MEPS and two patients a good MEPS. The QuickDASH scores were low in all patients. There were two patients with cubitus varus who were treated surgically using lateral closing-wedge corrective osteotomy. CONCLUSION: Infrafossal fracture of the humerus is a fracture type which is different from supracondylar and transcondylar fractures and has not been previously reported in the literature. Despite the cubitus varus developed in two of our patients, functionally satisfactory results were achieved in all patients at the end of the treatment. Due to the risk of developing cubitus varus, patients with infrafossal fracture of the humerus should be followed closely until the end of adolescence. Although the current study is very limited in terms of being a guide for the treatment, it may contribute to the literature in terms of defining a new fracture subtype.

A new custom-made plate preparation method for bony mallet finger treatment and a comparison with extension block technique.

OBJECTIVES: In this study, we aimed to describe a new hook plate technique (HPT) and to compare our results with the conventional extension block technique (EBT) with a Kirschner wire (K-wire) for bony mallet finger treatment. PATIENTS AND METHODS: Between April 2015 and January 2018, a total of 19 patients including 10 who were treated with EBT (7 males, 3 females; mean age: 30.1±7.3 years; range, 17 to 48 years) and nine who were treated with HPT (6 males, 3 females; mean age: 31.7±11.3 years; range, 19 to 42 years) for bony mallet finger with distal interphalangeal (DIP) joint subluxation and/or fracture fragment larger than one-third of distal phalanx (Wehbe-Schneider type 1/b, 2/a, 2/b, 3/a) joint were retrospectively analyzed. The DIP range of motion (ROM), Warren and Crawford scores, time to return to work/daily activity, operation time, the number of fluoroscopy shots, cost and complications were compared. RESULTS: No significant difference was found in the DIP ROM (p=0.708) and the Warren/Norris and Crawford scores (p=0.217 and p=0.175, respectively) between the two groups. Operation time and material cost were higher with HPT (p=0.006, p=0.001). There was no significant difference in the number of fluoroscopy shots (p=0.344). Although DIP joint motion was started at two weeks in the HPT group and at eight weeks in the EBT group, no significant difference was observed in the time of return to work and normal daily life in both groups (p=0.859). Complications were observed in two patients in the EBT group and in three patients in the HPT group. No significant difference in total complications was observed between the two groups (p=0.666). CONCLUSION: Bony mallet finger treatment with a custom-made hook plate prepared from 1.3-mm AO plates appeared to be clinically and radiologically similar to EBT. Additionally, HPT had the advantages of allowing early ROM to DIP joint and eliminating the need for a secondary surgery such as K-wire removal. On the other hand, hardware cost with HPT was higher than EBT.

Ponseti management of clubfoot after walking age.

BACKGROUND: With an incidence of 1-2 per 1000 live births, clubfoot is one of the commonest congenital deformities. Deformity has four components: equinus, hindfoot varus, forefoot adductus, and cavus. The Ponseti method for the treatment of clubfoot has been shown to be effective in children up to one year of age. Even with this effective method, late-presenting cases are still challenging. The aim of this study is to evaluate the corrective effect of the Ponseti method on different components of clubfoot after walking age and to find how the patient's age relates to this correction. METHODS: From 2003 to 2005 we treated 31 feet of 27 patients with clubfoot with a mean age of 21 months (12-72 months) with the Ponseti method. Average follow up was 42 months. All of the patients were evaluated before and after treatment for Dimeglio scores. Patients in the first group, aged less than 20 months, were compared with those in the second group, who were older than 20 months. The corrections for each component of the deformity were analyzed separately. RESULTS: All deformities showed significant correction. Improvements for each separate component were found to be statistically significant. Patients older than 20 months improved less for the components of varus, medial rotation of calcaneopedal block and adductus compared to younger patients. CONCLUSIONS: The Ponseti method is effective in correcting deformities of clubfoot, even after walking age, but affectivity may decrease with age.
