Reconstruction of the glenoid using autologous bone-graft and the SMR Axioma TT metal-backed prosthesis: the first 45 sequential cases at a minimum of two years' follow-up.

AIMS: We present our experience of using a metal-backed prosthesis and autologous bone graft to treat gross glenoid bone deficiency. PATIENTS AND METHODS: A prospective cohort study of the first 45 shoulder arthroplasties using the SMR Axioma Trabecular Titanium (TT) metal-backed glenoid with autologous bone graft. Between May 2013 and December 2014, 45 shoulder arthroplasties were carried out in 44 patients with a mean age of 64 years (35 to 89). The indications were 23 complex primary arthroplasties, 12 to revise a hemiarthroplasty or resurfacing, five for aseptic loosening of the glenoid, and five for infection. RESULTS: Of the 45 patients, 16 had anatomical shoulder arthroplasties (ASA) and 29 had reverse shoulder arthroplasties (RSA). Postoperatively, 43/45 patients had a CT scan. In 41 of 43 patients (95%), the glenoid peg achieved > 50% integration. In 40 of 43 cases (93%), the graft was fully or partially integrated. There were seven revisions (16%) but only four (9%) required a change of baseplate. Four (25%) of the 16 ASAs were revised for instability or cuff failure. At two-year radiological follow-up, five of the 41 cases (11%) showed some evidence of lucent lines. CONCLUSION: The use of a metal baseplate with a trabecular titanium surface in conjunction with autologous bone graft is a reliable method of addressing glenoid bone defects in primary and revision RSA setting in the short term. ASAs have a higher rate of complications with this technique.

Clinical evaluation of changes in cornea and tear film after surgery for trachomatous upper lid entropion.

PURPOSE: To determine the effect of entropion surgery on corneal health in terms of surface epithelium, tear film stability, change in curvature and vision. METHODS: Prospective study; included consecutive patients with trachomatous upper lid entropion undergoing corrective surgery. Corneal opacity and other conditions that reduced vision were recorded. Best-corrected visual acuity, corneal fluorescein staining, tear film break-up time, Schirmer I test, and keratometry were performed before and after surgery. Data were analysed using Student's t-test, chi(2) test, one-way ANOVA, one-sample t-test, and logistic and multiple regression. RESULTS: Thirty-six female and 15 male patients with an average age of 59.1+/-10.65 years were included. Lenticular and retinal causes resulted in blindness (P=0.008), and low vision (P=0.02), more often than entropion. At 90 days after surgery, vision improved by 0.55+/-1.48 lines (P=0.01). Superficial punctate staining of the cornea reduced by half over 1-15 days (average 6.96+/-4.99) after surgery, and completely in 1-90 days (average 26.15+/-17.49). Tear film break-up time (range: 3-20 s preoperatively) improved significantly after surgery (P=0.005) whereas Schirmer I (range: 10-35 mm preoperatively) and keratometry values showed insignificant change. CONCLUSIONS: Surgery for entropion results in healing of superficial keratopathy, improves tear film stability, and the realigned lid margin spreads tears evenly and efficiently, thus contributing to improved vision. These changes, taking place over 1-90 days, should be kept in mind when planning intraocular surgery, keratoplasty, or keratorefractive procedures after entropion correction.

Arthroscopic reconstruction of the anterior cruciate ligament using bone-patellar tendon-bone autograft: experience of the first 100 cases.

PURPOSE: To review the results of patients who underwent arthroscopic reconstruction of the anterior cruciate ligament (ACL) via a single incision technique using a bone-patellar tendon-bone autograft. METHODS: Patients with ACL-deficient knees who were symptomatic and wanted to maintain an active lifestyle or continue sporting activities were included. ACL reconstruction using the bone-patellar tendon-bone graft was performed on 100 patients. One-year follow-up was completed in 78 patients who were then reviewed. The mean age of patients reviewed was 26.8 years (range, 21-39 years), of whom 35 (44.9%) were aged between 26 and 30 years. There were 73 men and 5 women (ratio, 14.6:1). Injuries on the right side outnumbered those on the left (44 versus 34). Sports injuries accounted for 66.7% (n = 52) of patients, motor vehicle accidents and household injuries accounted for 30.8% (n = 24) and 2.6% (n = 2), respectively. RESULTS: Excellent and good-to-excellent results were achieved in 7 (9%) and 61 (78.2%) of patients. Residual anterior knee pain (n = 18) was the most common complication, followed by difficulty in regaining full range of motion (n = 10) and divergence of femoral screw (n = 9). CONCLUSION: This procedure provides consistent and reproducible results in carefully selected patients and allows them an early return to sporting activities with minimal residual morbidity.
