When performing diagnostic and surgical arthroscopic procedures on the shoulder, the importance of patient positioning cannot be understated. The optimum patient positioning for shoulder arthroscopy should enhance intraoperative joint visualization and surgical accessibility while minimizing potential perioperative risk to the patient. Most shoulder arthroscopy procedures can be reliably performed with the patient either in the lateral decubitus (LD) or beach chair (BC) position. Although patient positioning for shoulder arthroscopy has been subject of controversy, there is no conclusive evidence to suggest superiority of one position versus another. Each position offers advantages and disadvantages and surgeon's experience and training are pivotal on selecting one position versus another. Regardless of the position, a proper positioning of the patient should provide adequate access to the joint while minimizing complications. The purpose of this review is to summarize setup and technical aspects, the advantages and disadvantages, and the possible complications of the LD and BC positions in shoulder arthroscopy.

Orthopaedic procedures can affect patients' ability to perform activities of daily living, such as driving automobiles or other vehicles that require coordinated use of the upper and lower extremities. Many variables affect the time needed before a patient can drive competently after undergoing orthopaedic surgery to the extremities. These variables include whether the patient underwent upper or lower extremity surgery, the country in which the patient resides, whether the right or left lower extremity is involved, whether the dominant arm is involved, whether the extremity is in a cast or brace, whether the patient has adequate strength to control the steering wheel, and whether the patient is taking pain medication. The type and complexity of the procedure also influence the speed of return of driving ability. Few studies provide definitive data on driving ability after upper or lower extremity surgery. Patients should be counseled not to drive until they can control the steering wheel and the pedals competently and can drive well enough to prevent further harm to themselves or to others. This review discusses the limited recommendations in the literature regarding driving motorized vehicles after upper or lower extremity orthopaedic surgery.

Background It has been suggested that, during primary shoulder arthroplasty, surgeons should identify the axillary nerve through direct visualization, palpation, or the “tug test” to prevent iatrogenic nerve injury. Our goal was to document the rate of isolated axillary nerve injury (IANI) in patients who had undergone primary anatomic total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA) without routine identification of the axillary nerve. Methods Data on 869 cases of primary shoulder arthroplasty (338 TSAs and 531 RTSAs) performed by 1 surgeon between 2003 and 2017 were reviewed. Neither the tug test nor identification of the axillary nerve through palpation or visualization was used in any case. The primary outcome was new IANI documented within 3 months after arthroplasty. The frequency of IANI was summarized using point estimates and 95% confidence intervals (CIs). Results Six cases met the criteria for IANI. The overall incidence of IANI was 0.7% (95% CI, 0.3%-1.4%). The incidence of IANI was 0.3% (95% CI, 0%-1.6%) after TSA and 0.9% (95% CI, 0.3%-2.1%) after RTSA. All IANIs were cases of neurapraxia, and all patients had experienced complete neurologic recovery at last follow-up. Conclusion Complete, permanent IANI resulting from direct surgical trauma during primary shoulder arthroplasty can be avoided without using the tug test or routine identification of the nerve. A low incidence of partial temporary IANI can be expected, which may be related to indirect traction injuries.
