Output Clinical Function Oxford Shoulder Score After Surgery with Modified Weaver Dunn Technique in Cases of Acromioclavicular Joint Injury

Introduction

Acromioclavicular (AC) joint injuries are a common type of shoulder injury that can have a significant impact on a person's quality of life. The AC joint is a complex structure that connects the acromion and clavicle bones, and injuries to this joint can cause pain, limited mobility, and decreased function of the shoulder. Surgical intervention is often necessary to treat AC joint injuries, and one of the most commonly used techniques is the modified Weaver Dunn procedure. This study aims to evaluate the clinical function of patients who undergo surgery using the modified Weaver Dunn technique for AC joint injuries, with a focus on the Oxford Shoulder Score (OSS) and range of motion.

Research Purposes

The primary purpose of this study is to investigate the effectiveness of the modified Weaver Dunn technique in improving the clinical function of patients with AC joint injuries. Specifically, we aimed to compare the OSS scores and range of motion of patients who underwent surgery using the modified Weaver Dunn technique with those of a healthy control group. We also sought to identify any factors that may influence the outcome of the surgery, such as age, gender, and range of motion.

Research Methods

This study involved a retrospective analysis of eight patients who underwent surgery using the modified Weaver Dunn technique for AC joint injuries between 2011 and 2019. All patients met the inclusion criteria, which included a diagnosis of AC joint injury, a minimum of six months of follow-up, and a complete set of OSS scores and range of motion measurements. The data collected included patient demographics, OSS scores, and range of motion measurements, which were obtained at least six months after surgery.

Research Results

The patient characteristics are summarized in Table 1. There were three female patients and five male patients, with a mean age of 35.5 years (range: 25-50 years). The OSS scores and range of motion measurements are presented in Table 2.

Patient Characteristics	Mean (SD)
Age (years)	35.5 (10.3)
Gender (male/female)	5/3
OSS score (6 months post-op)	44.1 (13.0)
Range of motion (degrees)
Forward flexion	169.6 (8.3)
Extension	50.0 (26.7)
Abduction	169.4 (36.2)
Internal rotation	58.6 (23.3)
External rotation	49.4 (32.1)

The OSS scores and range of motion measurements were compared between the operated joints and the healthy joints. The results are presented in Table 3.

OSS Score and Range of Motion	Operated Joints	Healthy Joints
OSS score (6 months post-op)	44.1 (13.0)	46.9 (0.8)
Range of motion (degrees)
Forward flexion	169.6 (8.3)	177.9 (2.1)
Extension	50.0 (26.7)	58.3 (2.2)
Abduction	169.4 (36.2)	178.0 (2.1)
Internal rotation	58.6 (23.3)	63.4 (4.2)
External rotation	49.4 (32.1)	56.9 (3.7)

Conclusion

The results of this study suggest that the modified Weaver Dunn technique provides good functional outcomes in patients with AC joint injuries. The OSS scores and range of motion measurements were comparable between the operated joints and the healthy joints, indicating that the surgery was effective in improving the clinical function of the patients. These findings are consistent with previous studies that have reported good outcomes with the modified Weaver Dunn technique.

The Importance of This Research

This study is important because it provides insight into the effectiveness of the modified Weaver Dunn technique in treating AC joint injuries. The results of this study can help medical practitioners to make informed decisions about the treatment of patients with AC joint injuries, and can provide patients with realistic expectations about the outcome of surgery. Additionally, this study highlights the importance of rehabilitation and physical therapy in improving the clinical function of patients with AC joint injuries.

Limitations of the Study

This study has several limitations. The sample size was small, and the study was retrospective in nature. Additionally, the study only included patients who underwent surgery using the modified Weaver Dunn technique, and did not compare the outcomes with other surgical techniques. Future studies should aim to recruit a larger sample size and include a comparison group to provide a more comprehensive understanding of the effectiveness of the modified Weaver Dunn technique.

Future Directions

Future studies should aim to investigate the long-term outcomes of patients who undergo surgery using the modified Weaver Dunn technique. Additionally, studies should aim to compare the outcomes of different surgical techniques, including the modified Weaver Dunn technique, to determine which technique is most effective in treating AC joint injuries.
Q&A: Output Clinical Function Oxford Shoulder Score After Surgery with Modified Weaver Dunn Technique in Cases of Acromioclavicular Joint Injury

Q: What is the modified Weaver Dunn technique?

A: The modified Weaver Dunn technique is a surgical procedure used to treat acromioclavicular (AC) joint injuries. It involves the reconstruction of the AC joint using a graft, which is taken from the patient's own body or from a donor. The goal of the procedure is to restore the normal anatomy and function of the AC joint, allowing patients to regain their range of motion and strength.

Q: What is the Oxford Shoulder Score (OSS)?

A: The Oxford Shoulder Score (OSS) is a widely used assessment tool to evaluate the function and quality of life of patients with shoulder injuries or conditions. It consists of 12 questions that assess the patient's symptoms, function, and quality of life. The OSS score ranges from 0 to 60, with higher scores indicating better function and quality of life.

Q: What are the benefits of the modified Weaver Dunn technique?

A: The modified Weaver Dunn technique has several benefits, including:

Restoration of normal anatomy and function of the AC joint
Improved range of motion and strength
Reduced pain and discomfort
Improved quality of life
Reduced risk of further injury or complications

Q: What are the risks and complications associated with the modified Weaver Dunn technique?

A: As with any surgical procedure, there are risks and complications associated with the modified Weaver Dunn technique, including:

Infection
Bleeding
Nerve damage
Arthritis
Recurrence of the AC joint injury

Q: How long does it take to recover from the modified Weaver Dunn technique?

A: The recovery time from the modified Weaver Dunn technique can vary depending on the individual patient and the extent of the injury. Generally, patients can expect to spend several weeks to several months recovering from the procedure. During this time, patients will need to follow a rehabilitation program to regain their strength and range of motion.
