ABSTRACT
UNLABELLED: PURPOSE OF THE STUDY Although supracondylar humeral fractures represent a major part of the pediatric fractures, no classification system or radiological characteristics describes which supracondylar fractures require open reduction. We aim to evaluate the factors that lead us to perform open reduction during operation. MATERIAL AND METHODS We retrospectively evaluated 57 patients who underwent operation for type III supracondylar fracture, and divided them into two groups; those with open reduction and internal fixation, and those with closed reduction and percutaneous fixation. The two groups were compared based on age, gender, BMI by age, medial spike angle of the fracture, medial spike-skin distance and rotation angle between the fractured fragments. RESULTS Of all patients, 46 (81.71%) underwent closed reduction and percutaneous fixation (CRPF) and 11 (19.29%) were treated with open reduction and internal fixation (ORIF). BMI by age was remarkably higher in the ORIF group (p = 0.00). And medial spike angle was smaller in the ORIF group (p = 0.014). DISCUSSION Closed reduction and percutanous fixation is the main treatment of supracondylar humeral fractuers. Open reduction in supracondylar humeral fractures could be associate with complications and cosmetic lesions. Many studies indicates that obesity is high risk factor for complex fractures as well as preoperative and postoperative complications. A prominant medial spike could associate with muscle entrapment, and obliquity of the fracture line. It could be also an indirect finding of instablity of the fracture. CONCLUSION We suggest that a smaller medial spike angle and a higher BMI in children with Type III supracondylar humeral fractures may require open reduction, and it is unreasonable to avoid open reduction in cases where closed reduction is not achieved. KEY WORDS: supracondylar humerus, open reduction, obesity, medial spike angle.

PURPOSE OF THE STUDY: The purpose of this study was to evaluate clinical and functional results for a series of patients undergoing unicompartmental knee arthroplasty (UKA) at mid-term follow-up. MATERIAL AND METHODS: This study included 32 patients with isolated medial compartment arthritis who underwent unilateral UKA. Outcomes were assessed using pre- and postoperative Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scores and Knee Society Score (KSS) metrics. RESULTS: On physical examination at a follow-up of at least 5 years, mean knee flexion was 121° , mean knee extension was 2°, and mean varus angulation was 2°. At post-operative evaluation, the mean WOMAC score was 96.12 and the mean KSS score was 93. Pre- and postoperative WOMAC and KSS scores were evaluated by paired Student's t-tests; p < 0.001 determined a highly significant difference. DISCUSSION: Early UKA designs had poor outcomes. Newer implant designs and specific patient selection criteria have been reported to be associated with improved outcomes. This study examined mid-term outcomes (mean duration of follow-up, 5 years). CONCLUSION: The clinical and functional results of UKA at 5-year follow-up were shown to be satisfactory. Longer follow-up is needed to determine whether UKA provides satisfactory long-term outcomes.

The purpose of this study was to assess the accuracy of injections of dye into the first extensor compartment of the wrist using three different techniques in 150 wrists in 75 fresh cadavers. To compare injections, 50 wrists from 25 cadavers were used for each technique. After the injections, the first extensor compartment was dissected and the dispersion of dye around the abductor pollicis longus and extensor pollicis brevis tendons was investigated. In 72 % of all the wrists, acrylic dye was dispersed into one compartment containing both the abductor pollicis longus and extensor pollicis brevis tendons, but in 28% of the wrists there was a separate compartment for extensor pollicis brevis and dye entered only one of the compartments (14% for each compartment). For accurate injections, we think the injections should be made separately over the two tendons, to allow for the possibility of a septum within the compartment.
