Most common current surgical treatment options for cuff tear arthropathy (CTA) are hemiarthroplasty and reverse total shoulder replacement. At our unit we have been using Reverse Total shoulder replacement (TSR) for CTA patients since 2001. We present our results of Reverse TSR in 64 patients (single surgeon) with a mean follow up of 2 years (Range 1 to 8 years). There were 45 males and 19 females in the study with a mean age of 70 years. Preoperative and postoperative Constant scores were collected by a team of specialist shoulder physiotherapists. Preoperatively plain radiographs were used to evaluate the severity of arthritis and bone stock availability.

90% patients showed an improvement in the Constant score post operatively. The mean improvement in Constant score was 25 points. The mean Pain Score (max 15) improved from 6.3 to 11.8; the mean ADL Score (max 20) improved from 6.8 to 12.3; the mean Range of Motion score (max 40) improved from 10.8 to 20.2; but the mean Power Score (max 25) only improved from 0.9 to 4.9. The differences in improvement were statistically significant in each category. A total 6 patients (10%) required 10 revision surgeries for various reasons. Two patients dislocated anteriorly who were treated by open reduction. Two patients required revision of the glenoid component due to loosening after a mean of 2 years. One patient required revision of the humeral component with strut grafting secondary to severe osteolysis. Only one patient required revision of both humeral and glenoid components secondary to malpositioning. Three patients died for reasons unconnected with their shoulder problems and surgery. Radiographic analysis at the latest follow up (mean 24 months) showed inferior glenoid notching in 40% cases. Heterotrophic ossification was not seen in our series.

We conclude that reverse TSR is a viable option for treatment of cuff tear arthropathy however glenoid loosening and scapular notching remains an issue.

The study was designed to determine the incidence and to quantify the risk factors of permanently decreased bone mineral density (BMD) of the Lumbar spine and Femoral neck following tibial shaft fractures.

42 consecutive adults treated for isolated tibial shaft fractures at our institution between January 1984 and June 1985 formed the subjects of this study. Mechanism and type of injury, method of treatment, length of immobilisation and weight bearing status and healing time were determined from the patient records. A questionnaire including history of smoking, alcohol consumption, medications, other fractures, medical conditions like thyroid/parathyroid disorders, convulsions, and renal disorders was administered. Bone mineral density of lumbar 1–4 vertebrae and both hips was assessed using DEXA scanning. T and Z scores were generated. Statistical analysis was performed using the Chi square test to test the significance of association of osteopenia/osteoporosis (Z score < -1) with a previous tibial shaft fracture and calculating the odds ratio (OR) and 95% confidence interval (CI) to quantify the suspected risk factors.

The incidence of significant loss of BMD of the ipsilateral femur and/or lumbar spine was found to be 33%. A statistically significant association (p< 0.001) between a history of tibial shaft fracture and permanent loss of BMD was noted. The following risk factors were found to be statistically significant; Smoking (OR 22, 95% CI=4–> 40, p< 0.001), Alcohol more than 20 units/week (OR 11, 95% CI 2.2–54,p< 0.005), Open fracture (OR 17, 95% CI=2.9–> 40, p< 0.001), Non-weight bearing more than 12 weeks (OR 15, 95% CI 2.9–> 40, p< 0.005), and delayed union defined as healing time more than 6 months (OR 15, 95% CI 1.54–> 40, p < 0.05).

Permanent regional osteopaenia/osteoporosis occurs in a significant proportion of tibial shaft fracture patients. Modern fracture management should include identifying ‘at risk’ patients and appropriate management to prevent fragility fractures.
