The shoulder is the most versatile and dynamic joint in the human body. It offers more range of motion that any other joint, giving you the ability to do anything from combing your hair, to climbing a ladder, to throwing a ball.
This ability relies on a complex interaction between a ball (humeral head) and a socket (the glenoid) as well as the shoulder blade and the chest wall (thorax). These interactions are heavily dependent on complex interactions between multiple soft tissues including the cartilage, ligaments and muscles/tendons.
Any disruption or injury of these balanced interactions can cause significant pain, impairment, and possible disability. Accurate diagnosis of these injuries or conditions is the first step in returning the joint to an optimal function.

Spinal injuries and disorders can be major life-changing events. Whether caused by trauma, infection, degenerative disorder, or tumors, a spine or spinal cord condition can result in a drastic change in the lives of patients and their families.

Appropriate, non-operative management of spinal injuries or conditions is always the first choice. This may include physical therapy, medications, corticosteroid injections or other therapeutic measures. Factors affecting the decision between operative and non-operative treatment include the type of injury or condition, previous treatments attempted and primarily the functional needs of the patient. The patient will be given all of the information necessary to make an informed decision in their care.

The elbow is a joint formed by the articulation of three bones in the upper extremity, the humerus, radius and ulna. Stability of the elbow is a complex interaction involving both hard tissue (bone and cartilage) and soft tissue (ligaments and tendons) elements. Both of these are critical to the function of the elbow in the performance of complex activities such as throwing a ball and simpler activities like brushing your hair or teeth.


Dr. Lenarz is an expert in the treatment of complex injuries and conditions of the elbow including fractures, arthritis, instability/dislocations, ligament injuries (Tommy John), tendon injuries (biceps and triceps) and simpler problems like Golfer’s and Tennis Elbow (epicondylitis). Some of these conditions can be treated with minimally invasive, percutaneous or arthroscopic techniques and some require more complex open techniques.
