“…[13,14] For instance, in developmental dysplasia of the hip, a pediatric orthopedic surgeon may need to perform several tasks in a single session in the operating room such as adductor tenotomy, open reduction, acetabuloplasty, and femoral shortening osteotomy. [15,16] All these tasks involve using sharp tools and instruments which, if not handled properly, can cause serious occupational injuries. These tools and instruments include needles, scalpels, a cutting saw, sharp retractors, bone hooks, osteotomes, drills, and screws.…”

In this cross-sectional study, we surveyed all pediatric orthopedic surgeons in Saudi Arabia using an anonymous electronic questionnaire composed of 23 items to identify the rate of occupational injuries and obtain other relevant information. Thirty-nine participants completed the questionnaire (response rate: 83%). Participants who sustained occupational injuries throughout their careers represented 82.5%. The most injured areas were the hands, eyes, and back by 54.5%, 24.2%, and 15.2%, respectively. Approximately 11.1% were injured while operating on infected patients. Approximately 30.3% reported their injuries to their institution. We concluded that the rate of occupational injuries among pediatric orthopedic surgeons is very high and underreported.

“…An increase was also detected in CEA by means of reduced acetabular dysplasia and normal development of well-covered femoral head. Ming-Hua et al found CEA as 29° after the high osteotomy cut Dega procedure (20). In another study, it was detected as 31° in average (27).…”

“…In the literature, there is not a particular consensus on the age limit. However, the remodalization capacity was stated to be decreased towards the age of 6 (20,28). Ponseti revealed that the acetabulum has been developed and acetabular depth has been increased by means of interstitial growth in the acetabular cartilage, the appositional growth at the periphery of this cartilage and periosteal new-bone formation at the acetabular margin (29).…”

Objective: To examine hip development in a patient who underwent Dega osteotomy due to developmental dysplasia of the hip (DDH) by means of radiography. Materials and Methods: Dega osteotomy was performed on 43 hips (7 were bilateral) of 36 patients with DDH. In preoperative and final follow-up; the acetabular index (AI), acetabular depth ratio (ADR) and Wiberg's center-edge angle (CEA) were measured in anteroposterior pelvic radiographs. Hips were classified in accordance with Tönnis classification system. Radiological findings were evaluated in accordance with Severin classification system. Avascular necrosis (AVN) of the hips were evaluated according to Kalamchi-MacEwen classification system. Results: The mean age was 87 months (48-130 months), mean follow-up period was 30.5 months (15-62 months). The mean preoperative and final follow-up values of AI were 43° (28°to 60°) and 19° (6° to 34°), respectively. The mean preoperative and final follow-up values of ADR were detected as 14 (8 to 24) and 26 (18 to 42), respectively.The mean CEA was found as 38° (18° to 61°) at the final follow-up. Of the hips, 37 were Tönnis type 4 and 6 were Type 3. Totally 10 hips had AVN; of those, 6 were Type 1, 2 were Type 2 and 2 were Type 3 hips. According to Severin classification, 11 hips were Type 1a, 3 were Type 1b, 22 were Type 2a, 5 were Type 2b and 2 were Type 3. Conclusion: In patients who underwent Dega osteotomy, hip development can be detected radiographically with satisfactory levels.

“…In the procedure by Raichel and Hein, the medioposterior cortical corner remains intact, representing the rotation center, the point where the acetabular roof is deflected to the lateral and anterior sides. 14 Ming-Hua et al 30 described their modified technique, also known as 'the high Dega osteotomy', in children with DDH aged between 1.5 and 6 years. The osteotomy cut at a higher level is similar to the Salter pelvic osteotomy.…”

BackgroundWe aim to describe a modified Dega osteotomy technique in detail, emphasizing its eventual advantages in comparison to the original Dega osteotomy and ‘San Diego’ modification. We also present our related literature review on various osteotomy techniques.MethodsWe reviewed the radiological indices of 27 dysplastic hips in 25 children with cerebral palsy and developmental dislocation of the hips (9 boys, 16 girls; mean age, 5 years) who underwent a modified Dega osteotomy according to Paley.ResultsComparing the radiological indices results between our patients and those reported by the various authors in the literature, the data are almost identical.ConclusionsThe modified Dega osteotomy is the only technique wherein all two limbs of the triradiate cartilage are true, which becomes a single hinge where the osteotomy turns. Despite the similar results in the radiological indices between our patients and those in the literature, we still consider that the entire triradiate cartilage is a better hinge point for the iliac osteotomy. The difference between the osteotomy adopted in our institution and the modality described by most authors in the literature is that the latter mostly ignore or miss the ischial limb of the triradiate cartilage.

The high osteotomy cut of Dega procedure for developmental dysplasia of the hip in children under 6 years of age

Abstract: The high osteotomy cut Dega procedure for patients between 1.5 and 6 years of age was found to be sufficient for improving clinical and radiographic outcomes and inducing little morbidity and few complications for late-detected pediatric walking DDH patients.
