Positioning should be done with the help of the attending physician to be certain that appropriate exposure is achieved and that the patient rests in a comfortable position during surgery. The drapes should be securely fixed to the patient, preferably with adhesive rather than staples or towel clamps (Fig. 15.3). Care in removing drapes is essential to avoid injury especially to age related skin atrophy; for example, circular bandages should be unrolled to avoid injury as is more likely if cut.

Shorter surgical time reduces the risk of wound infection, blood loss (Fig. 15.4), untoward effects of the anesthetic, and likely cognitive dysfunction (Fig. 15.5). Proper fluid management is vital to reduce complications [5053].

Clinical assessment of the patient’s volume and hemoglobin status is essential in every patient. Fluid depletion is best corrected with isotonic saline with caution to avoid over expansion. The NIH-sponsored FOCUS trial, Safety and Effectiveness of Two Blood Transfusion Strategies in Surgical Patients with Cardiovascular Disease, suggests maintaining hemoglobin levels at or above 8 g/dL for elderly patients with cardiac comorbidities [54].

Because of poor bone quality arthroplasty is valuable and a variety of cemented implants should be available.

Hip fracture, femur fracture, and periprosthetic fracture should be performed urgently for reasons noted earlier. Proximal humerus fracture and distal radius fracture surgery can be semi-elective. A detailed care pathway discussed early is able to improve outcome quality, patient satisfaction, and lower costs [3, 4, 17, 22].

15.15 Postoperative Care

Postoperative care should be standardized and protocol driven and ideally involving an interprofessional team.

Pain management is complex: under-reporting, especially in those with cognitive impairment, and analgesics have an increased side-effect profile in older people. Multimodal analgesia using narcotics, non-narcotic analgesics, and local nerve blocks is effective [5558]. The combination of NSAIDs/acetaminophen with opiates produces synergistic pain relief and decreases the need for opioid medications. Intravenous, oral and subcutaneous morphine, fentanyl, and hydromorphone have no difference in the deterioration of cognitive function or incident delirium [57]. Meperidine causes delirium and should be avoided [58].

Intravenous patient-controlled analgesia (PCA ) provides superior postoperative pain relief compared to nurse administered boluses but because of comorbidities, especially brain disease and hand arthritis it may not be effective in some seniors.

Meta-analyses found that local nerve blocks are effective and reduce complications in femur fracture [59, 60].

In most situations, the goal of orthopedic surgical intervention is to restore the patient to their prior level of activity and independence, or to an increased level of independence. A secondary goal of surgery is to prevent the complications of immobility and its sequelae—pressure sores, stiff joints, deconditioning, pneumonia, and delirium. In almost all cases, rehabilitation should begin soon after surgery. Every surgeon has his or her own preference in the initiation of mobility and physical therapy and these differences depend on the surgery performed (a patient with total knee arthroplasty may immediately bear weight as tolerated while one with a tibial plateau fracture may be non-weight bearing for some time). The surgeon must decide on this status, and engaging early physical and occupational therapists is most valuable to achieve the best outcomes, avoid complications, and achieve ideal analgesia [6163].

Braces are best avoided but occasionally one is essential: tibial plateau fracture, some ankle fractures, and minor wrist fractures management. Complications of braces include delirium, pressure pain, tendon injury, and skin breakdown.

Orthopedic patients are especially vulnerable to skin injury. Pressure sores are serious complications and can lead to hospital readmission, sepsis, surgery, and death. With high quality care they are largely preventable. Doing so lies in careful bedside care. Skin must be checked several times a day for proper positioning, padding, redness, blisters, and ulcers. Sores most commonly are found at the hips, sacral region, heels, and elbows. Routine and frequent skin assessment and care by members of the multi- or interdisciplinary team is most valuable in avoiding or managing skin pressure problems. Such an approach is better than the common practice of the past, which included routine repositioning (an activity that can cause a shear injury, a precursor to an ulcer), pressure relieving mattresses or beds. Interdisciplinary team care and early mobilizations are effective strategies in reducing skin injury [6467].

Evaluation tools for assessing risk of pressure ulcers include the Braden [68] and Norton [69] scales. The Norton scale may be better at identifying high-risk patients [69]. Grip strength (possibly as a surrogate for sarcopenia) predicts inpatient and 30-day risk of pressure ulcers [70].

Delirium is a common and serious complication in the postoperative affecting about half of patients after hip fracture and increasing mortality and length of stay [4, 7174]. Certain medications sometimes used perioperatively (anticholinergics, benzodiazepines, skeletal muscle relaxants, and NSAIDs) are important precipitants and are best avoided. Other risk factors and strategies to minimize this complication are discussed in depth in Chap. 2.

Falls in the elderly are often multifactorial. Reducing the risk of a future fall is of utmost importance. A home safety evaluation should be considered when necessary, and proper modifications implemented (Fig. 15.6).

With the increasing popularity of bisphosphonates , atypical bisphosphonate-related femur fractures have become more common (Fig. 15.7). For patients undergoing osteoporosis treatment with this class of medication, it is important to determine the risk of fracture of the contralateral side in the postoperative period.

The risk of complications, poor outcomes, and mortality in older orthopedic patients requiring surgery is high, a result of many comorbidities, losses of physiological function and remarkable heterogeneity. Such patients are simply more vulnerable, and perioperative care requires a highly orchestrated interdisciplinary team to achieve the best outcomes [7585].
