Soft Tissue Release for Elbow Pronation in Cerebral Palsy
Distal Soft Tissue Release for Elbow Pronation Deformity in Cerebral Palsy: Functional Outcomes
Upper extremity deformities are highly common in individuals with cerebral palsy (CP) as a result of motor control impairment and muscle imbalance. Among these deformities, elbow pronation deformities are frequently observed, particularly in spastic-type CP (Koman et al., 2004). The imbalance between the pronator muscle group (pronator teres, pronator quadratus) and the supinator muscle group (supinator, biceps brachii) leads to the forearm remaining in a persistent pronated position (Sahoo et al., 2017). This deformity is not only aesthetically concerning but also results in significant functional limitations. Both fine and gross motor skills-such as washing the face, handshaking, and clapping-are adversely affected (Soutar & McComas, 1990). Additionally, children may experience difficulty using assistive devices such as walkers, which in turn can negatively impact ambulation (Flett, 2003).
An elbow fixed in pronation forces children to compensate for limited range of motion by using shoulder and trunk movements, which over time predisposes them to abnormal postural development (Gracies, 2005). In advanced cases, structural alterations such as posterolateral radial head dislocations may also occur (Van Heest & House, 2000). Both conservative (orthoses, botulinum toxin injections, physical therapy) and surgical interventions are employed in the treatment of pronation deformities. Surgical options include tenotomy of the pronator teres and pronator quadratus, muscle transfers, or combined procedures (Zancolli, 1975). However, there is no consensus in the literature regarding which surgical method should be applied to which patient group and at what stage (House et al., 1981).
The aim of this study is to evaluate the effects of distal soft-tissue release surgery for the treatment of elbow pronation deformity on upper extremity function in children with cerebral palsy.

Descrição detalhada
The aim of this study is to evaluate the effects of distal soft-tissue release surgery, performed for elbow pronation deformity in children with Cerebral Palsy (CP), on upper extremity functions. By comparing pre-operative and post-operative measurements, the study will determine the presence and extent of functional improvement.
- H1:** Distal soft-tissue release surgery performed for elbow pronation deformity in children with Cerebral Palsy has a significant effect on upper extremity functions.
- H0:** Distal soft-tissue release surgery has no significant effect on upper extremity functions.
This study will be conducted as a prospective, observational study with long-term follow-up after the intervention.
A total of 20 children aged 6-16 years, diagnosed with spastic-type CP and scheduled for surgery due to forearm pronation deformity, will be included. Participants will undergo distal soft-tissue release targeting the pronator quadratus muscle (Zancolli, 1975; Van Heest & House, 2000). The upper extremity functional level of participants will be assessed using the **HOUSE Classification**; motor abilities using the **Manual Ability Classification System (MACS)**; motor quality using the **Quality of Upper Extremity Skills Test (QUEST)**; range of motion using **goniometric measurements**; function and aesthetics using the **Shriners Hospital Upper Extremity Evaluation (SHUEE)**; hand skills using the **Bimanual Fine Motor Function Test (BFMF)**; and quality of life using the **Pediatric Quality of Life Inventory (PedsQL)**. Assessments will be performed preoperatively and at six-month intervals for two years following surgery.
Data will be analyzed using SPSS software, with the significance level set at p < 0.05.
Although the literature includes various descriptive studies on the functional effects of pronation deformity in children with CP (Koman et al., 2004; Gracies, 2005), there is a limited number of studies evaluating the functional outcomes of distal soft-tissue interventions for this deformity (Sahoo et al., 2017). By objectively assessing the impact of surgical intervention on daily living activities and social participation, this research aims to contribute evidence-based insights to clinical decision-making processes. Moreover, the study aims to highlight the importance of function-oriented interventions for individuals with CP who experience upper extremity deformities, thereby providing data to support appropriate patient selection and timing of intervention in the early period.

Prazo |
|---|---|---|
|
House Classification
Prazo: 5 times (pre-opperative, 6. month, 12. month, 18. month, 24. month)
|
Upper extremity function will be assessed using the House Functional Classification System.
The scale classifies spontaneous use of the affected upper extremity during daily activities into 9 levels (0-8), where higher scores indicate better upper extremity function.
|
5 times (pre-opperative, 6. month, 12. month, 18. month, 24. month)
|
|
Manual Ability Classification System
Prazo: 5 times (pre-opperative, 6. month, 12. month, 18. month, 24. month)
|
Manual ability will be assessed using the Manual Ability Classification System (MACS), a 5-level classification system evaluating how children use their hands to handle objects in daily activities.
Level I indicates the best manual ability and Level V indicates the most severe limitation.
|
5 times (pre-opperative, 6. month, 12. month, 18. month, 24. month)

Upper extremity motor skill quality will be assessed using the Quality of Upper Extremity Skills Test (QUEST).
The assessment evaluates dissociated movements, grasp, weight bearing, and protective extension.
Scores range from 0 to 100, with higher scores indicating better upper extremity motor performance.
