History of rotator cuff surgery.

PURPOSE: Rotator cuff surgery is a rapidly evolving branch in orthopaedics, which has raised from a minor niche to a fully recognized subspecialty. This article summarizes its history, examining the development of its key principles and the technical advancements. METHODS: Literature was thoroughly searched, and few senior surgeons were interviewed in order to identify the significant steps in the evolution of rotator cuff surgery. RESULTS: A wide variety of surgical options is available to reduce pain and restore function after rotator cuff tears. Rotator cuff repair surgical techniques evolved from open to arthroscopic and are still in development, with new fixation techniques and biological solutions to enhance tendon healing being proposed, tested in laboratory and in clinical trials. Although good or excellent results are often obtained, there is little evidence that the results of rotator cuff repair are improving with the decades. An overall high re-tear rate remains, but patients with failed rotator cuff repairs can experience outcomes comparable with those after successful repairs. CONCLUSIONS: Rotator cuff repair techniques evolve at a fast pace, with new solutions often being used without solid clinical evidence of superiority. It is necessary to conduct high-level clinical studies, in which data relating to anatomical integrity, patient self-assessed comfort and function, together with precise description of patient's condition and surgical technique, are collected. LEVEL OF EVIDENCE: IV.

Post-operative rehabilitation after surgical repair of the rotator cuff.

Today advances in techniques and materials for rotator cuff surgery allow the repair of a large variety of types or extensions of cuff lesions in patients from a wide range of age groups who have different kinds of jobs and participate in different kinds of sports, and who have widely different expectations in terms of recovery of functions and pain relief. A large number of factors must be taken into account before implementing a rehabilitation protocol after rotator cuff surgery. These mainly include the technique (materials and procedure) used by the surgeon. Moreover, tissue quality, retraction, fatty infiltration and time from rupture are important biological factors while the patient's work or sport or daily activities after surgery and expectations of recovery must also be assessed. A rehabilitation protocol should also take into account the timing of biological healing of bone to tendon or tendon to tendon interface, depending on the type of rupture and repair. This timing should direct the therapist's choice of correct passive or assisted exercise and mobilisation manoeuvres and the teaching of correct active mobilisation movements the patient has to do. Following accepted knowledge about the time of biological tissue healing, surgical technique and focused rehabilitation exercise, a conceptual protocol in four phases could be applied, tailoring the protocol for each patient. It starts with sling rest with passive small self-assisted arm motion in phase one, to prevent post-op stiffness. In phase two passive mobilisation by the patient dry or in water, integrated with scapular mobilisation and stabiliser reinforcement, are done. Phase three consists of progressive active arm mobilisation dry or in water integrated with proprioceptive exercise and "core" stabilisation. In phase four full strength recovery integrated with the recovery of work or sports movements will complete the protocol. Because of the multi-factorial aspects of the problem, the best results can be obtained through a full transfer of information from the surgeon to the therapist to optimise timing and sizing of the individual rehabilitation protocol for each patient.

Incidence of risk in shoulder surgery : medical-legal repercussions.

It is generally recognised that any medical-surgical activity entails the risk of failure, placing the physician at risk of malpractice claims. In order to protect both the physician and the patient, it is important to identify the risk factors relating to the various pathological situations and assess both the incidence and significance of such risks. Hence, a "Potential Failure Rating" could be devised already during the preliminary stages for every type of medical process. Such a rating would be useful both in clinical and medicolegal settings. This article considers the most common and important risk factors involved in typical diseases of the shoulder, from which a relative failure rating is formulated.
