Functional outcome after nonoperative management of minimally displaced greater tuberosity fractures and predictors of poorer patient experience.

The outcomes following nonoperative management of minimally displaced greater tuberosity (GT) fractures, and the factors which influence patient experience, remain poorly defined. We assessed the early patient-derived outcomes following these injuries and examined the effect of a range of demographic- and injury-related variables on these outcomes. In total, 101 patients (53 female, 48 male) with a mean age of 50.9 years (19 to 76) with minimally displaced GT fractures were recruited to a prospective observational cohort study. During the first year after injury, patients underwent experiential assessment using the Disabilities of the Arm, Shoulder and Hand (DASH) score and assessment of associated injuries using MRI performed within two weeks of injury. The primary outcome was the one-year DASH score. Multivariate analysis was used to assess the effect of patient demographic factors, complications, and associated injuries, on outcome. The mean DASH score improved from 42.3 (SD 9.6) at six weeks post-injury, to 19.5 (SD 14.3) at one-year follow-up (p < 0.001), but outcomes were mixed, with 30 patients having a DASH score > 30 at one year. MRI revealed a range of associated injuries, with a full-thickness rotator cuff tear present in 19 patients (19%). Overall, 11 patients (11%) developed complications requiring further operative intervention; 20 patients (21%) developed post-traumatic secondary shoulder stiffness. Multivariate analysis revealed a high-energy mechanism (p = 0.009), tobacco consumption (p = 0.033), use of mobility aids (p = 0.047), a full-thickness rotator cuff tear (p = 0.002), and the development of post-traumatic secondary shoulder stiffness (p = 0.035) were independent predictors of poorer outcome. The results of nonoperative management of minimally displaced GT fractures are heterogeneous. While many patients have satisfactory early outcomes, a substantial subgroup fare much worse. There is a high prevalence of rotator cuff injuries and post-traumatic shoulder stiffness, and their presence is associated with poorer patient experience. Furthermore, patients who have a high-energy injury, smoke, or use walking aids, have worse outcomes.

Osteoporotic periprosthetic fractures of the femur in elderly patients: outcome after fixation with the LISS plate.

Longer patient survival and the extension of joint arthroplasty to older patients means that osteoporotic fractures of the femur are often associated with joint implants. This poses a significant trauma work load. This problem is likely to increase over time. The management of these periprosthetic fractures may be difficult and strategies are not universally agreed. Revision arthroplasty, single or double plate fixation with or without augmentation with methylmethacrylate or bone grafting, are all variously advocated in the literature for different indications. We retrospectively identified 28 elderly patients consecutively treated in our institution with Less Invasive Stabilisation System (LISS) plate fixation for osteoporotic and periprosthetic fractures of the femur. We present prospectively collected data for clinical and radiographic follow-up and patient outcomes. Patients had a mean age of 86.7 years. A fall from a standing height was the most common mechanism of injury. No cases of non-union were seen in survivors. Mortality in the first year was a major complication (5 patients). Rates of revision surgery were low (2 patients). Most patients required a formal period of rehabilitation, however, only half of the patients were successfully discharged to their own homes. The LISS plate provides good fixation in osteoporotic periprosthetic fractures of the femur. It restores a stable limb allowing early weight bearing as well as achieving clinical and radiographic union. Patients return to mobility levels approaching their pre-injury status although most benefit from a formal period of rehabilitation. In this patient group, the LISS plate often outlives the patient.

Treatment of anterior fracture-dislocations of the proximal humerus by open reduction and internal fixation.

Over a seven-year period we treated a consecutive series of 58 patients, 20 men and 38 women with a mean age of 66 years (21 to 87) who had an acute complex anterior fracture-dislocation of the proximal humerus. Two patterns of injury are proposed for study based upon a prospective assessment of the pattern of soft-tissue and bony injury and the degree of devascularisation of the humeral head. In 23 patients, the head had retained capsular attachments and arterial back-bleeding (type-I injury), whereas in 35 patients the head was devoid of significant soft-tissue attachments with no active arterial bleeding (type-II injury). Following treatment by open reduction and internal fixation, only two of 23 patients with type-I injuries developed radiological evidence of osteonecrosis of the humeral head, compared with four of seven patients with type-II injuries. A policy of primary treatment by open reduction and internal fixation of type-I injuries is justified, whereas most elderly patients (aged 60 years or over) with type-II injuries are best treated by hemiarthroplasty. The best treatment for younger patients (aged under 60 years) who sustain type-II injuries is controversial and an individualised approach to their management is advocated.

Trochanteric-entry long cephalomedullary nailing of subtrochanteric fractures caused by low-energy trauma.

BACKGROUND: Subtrochanteric fractures of the femur that are caused by low-energy trauma are less common than other proximal femoral fractures, but they occur in a similar population of elderly individuals, who are often socially dependent and medically frail. Although a wide range of operative techniques have been used, cephalomedullary nailing theoretically provides the most minimally invasive and biomechanically stable means of treating these complex fractures. The purpose of the present review was to evaluate the functional outcome and perioperative complications associated with the use of a trochanteric-entry cephalomedullary nail to treat all low-energy subtrochanteric fractures that were seen at a single institution. METHODS: Over an eight-year period, we used the long Gamma nail to treat a consecutive series of 302 local patients who had sustained a subtrochanteric fracture during low-energy trauma. The mortality, prevalence of complications, and functional outcome were prospectively assessed during the first year after the injury. Survival analysis was used to assess the rates of reoperation and implant revision during the first year after surgery. RESULTS: At one year, seventy-four (24.5%) of the original 302 patients had died and seventeen (5.6%) had been lost to follow-up. The remaining 211 patients (69.9%) were evaluated with regard to the functional outcome and postoperative complications during the first year after the injury. As with other proximal femoral fractures in the elderly, there was an increased level of social dependence, an increase in the use of walking aids, and a reduction in mobility among survivors. Although eighty-eight (41.7%) of the 211 patients who were evaluated at one year after the injury had some degree of hip discomfort, only two described the pain as severe and disabling. Reoperation for the treatment of implant or fracture-related complications was required in twenty-seven (8.9%) of the 302 patients; however, only eighteen of these patients required nail revision, corresponding with a one-year nail-revision rate of 7.1% (95% confidence interval, 4.0% to 10.2%) on survival analysis. Of the 250 patients who survived for six months after the injury, five (2%) had a nonunion that was confirmed at the time of surgical exploration. Complications related to the proximal lag screw were seen in twelve of the original 302 patients, and a fracture distal to the tip of the nail occurred in five. Although superficial wound infection was relatively common, deep infection occurred in only five of the 302 patients. CONCLUSIONS: Subtrochanteric fractures caused by low-energy trauma are similar to other proximal femoral fractures, with a high mortality rate during the first year after the injury. Trochanteric-entry cephalomedullary nails are associated with an acceptable rate of perioperative complications and favorable functional outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV.
