Pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture
A pseudo-arthrosis repair of a 4-year-old bony avulsion fracture of the PCL using a minimally invasive technique, screw fixation, and bone grafting is reported. The case presented seems to be rather unique due to the fragment size and the approach for pseudo-arthrosis repair. There was a good functional result following minimally invasive pseudo-arthrosis repair of a posterior cruciate ligament avulsion fracture. There are no previous reports of similar pseudo-arthrosis repairs, and other authors report good results of delayed refixation of PCL avulsion fractures. Therefore, refixation and pseudo-arthrosis repair should be considered as a viable treatment

Core Decompression and Bone Marrow Aspiration Concentrate Grafting for Osteonecrosis of the Femoral Head
BACKGROUND: Core decompression (CD) with bone marrow aspiration concentrate (BMAC) is a technique that may improve outcomes in osteonecrosis of the femoral head (ONFH). The primary aim of this study was to evaluate the radiographic progression free survival (PFS) of CD augmented with BMAC. Secondary aims were to determine the survivorship with conversion (CFS) to total hip arthroplasty (THA) as an endpoint, determine prognostic factors, and characterize the cellular quality of the BMAC. METHODS: A retrospective cohort study of 61 femoral heads (40 patients) was performed. Patient demographics, comorbidities, BMI, smoking status, etiology, location and extent of ONFH were recorded. The primary endpoint was radiographic progression of ONFH and secondarily, conversion to THA. Additional aims were to determine predictive factors for progression and report the cellular characteristics of the BMAC. Data obtained were compared to the results of a prior randomized controlled trial comparing CD alone versus CD with polymethylmethacrylate cement (PMMA) augmentation. RESULTS: Radiographic PFS of CD with BMAC at 2 and 5 years was 78.3% and 53.3%, respectively. The risk of progression was lower in the CD with BMAC group compared to CD alone (HR0.45, p = 0.03), however this difference no longer remained statistically significant on multivariate analysis. Conversion to total hip arthroplasty free survival (CFS) of CD with BMAC at both 2 and 5 years was 72.1% and 54.6%, respectively with no differences compared to the control groups (CD alone, CD and PMMA). The predictive factors for progression were obesity (BMI ≥ 30) and the extent of the disease as quantified by either percentage involvement, necrotic index or modified necrotic index. CONCLUSIONS: No differences in PFS or CFS between CD with BMAC compared to CD alone or CD with PMMA were identified. Independent statistically significant predictors of progression-free survival or conversion to THA are BMI ≥ 30 and the extent of ONFH. Further research with an adequately powered randomized controlled trial is needed. LEVEL OF EVIDENCE: 3
Midshaft clavicle fractures: Current concepts
▪ Clavicle fractures are common fractures and the optimal treatment strategy remains debatable. The present paper reviews the available literature and current concepts in the management of displaced and/or shortened midshaft clavicle fractures. ▪ Operative treatment leads to improved short-term functional outcomes, increased patient satisfaction, an earlier return to sports and lower rates of non-union compared with conservative treatment. In terms of cost-effectiveness, operative treatment also seems to be advantageous. ▪ However, operative treatment is associated with an increased risk of complications and re-operations, while long-term shoulder functional outcomes are similar. ▪The optimal treatment strategy should be one tailor-made to the patient and his/her specific needs and expectations by utilizing a shared decision-making model

Two-incision minimally invasive total hip arthroplasty - results and complications
The purpose of this study was to determine the complication rate and functional result after two-incision minimally invasive total hip arthroplasty in a retrospective consecutive case series of the first 45 patients treated by a single surgeon. The mean follow up period was 2.1 years. There were 4 early major complications (2 peri-operative fractures and 2 re-interventions) and 28 early minor complications (1 superficial infection and 27 patients with a loss of sensation of the lateral aspect of the thigh). One stem loosening required revision within two years. The mean modified Harris Hip Score at final follow-up was 91,5. Our experience shows a relatively high complication risk after two-incision minimally invasive total hip arthroplasty, and we have since abandoned this techniqu
