Elbow stiffness: Arthritis and heterotopic ossification.

In elbow stiffness, pre-operative assessments should identify the articular and peri-articular tissues involved and, more specifically, they should determine how preserved the articular surfaces and osteo-articular congruity are. We will focus on the most important conditions and tissue reactions after trauma in order to understand the causes of joint stiffness. A logical surgical planning is based upon a deep knowledge of the anatomical obstacles and of the associated lesions that the trauma provoked with. The peri-articular soft tissue contractures. The osteo-articular incongruity.

Encouraging mid-term outcomes for arthroscopic autologous osteochondral transplant (OAT) in capitellum osteochondritis dissecans (OCD).

PURPOSE: The primary outcomes are the evaluation and quantification of pain relief and improvement in range of motion after OAT in OCD. The secondary outcomes are: resuming of sport activities, evaluation of the ADL recovery rate and subjective evaluation of the quality of life improvement. METHODS: Nine patients, affected by an unstable and non-acute OCD lesion of the capitulum humeri, have been treated by the same surgeon. The patient mean age was 22.4 (16-45 years). All subjects were treated with the same surgical technique (arthroscopic OAT from the same side knee, a single cylinder of 6.5-9 mm in diameter) and underwent the same rehabilitation. The mean follow-up was 48 months (30-52 months). The authors documented the clinical assessment of each patient and carried out a questionnaire which included the VAS scale, MEPS Score and Quick DASH score. Patients were asked for MRI and radiographs pre- and post-operatively at follow-up. RESULTS: The mean range of motion improvement was 17.9° in extension (range 13°-27°) and 10.6° in flexion (range 0°-20°) The VAS mean improvement was 7.1 (range 6-8) and the mean post-op value 0.6 (range 0-3). The MEPS score mean post-operative value was 98.3 (range 85-100). The Quick-DASH mean post-operative value was 2.5 (range 0-9.1) with a mean improvement of 41.4 points (range 36.4-47.7 points). All patients resumed sports in 6 months post-operatively. CONCLUSIONS: The autologous transplant of an osteochondral plug is a safe and promising procedure. Despite being more demanding, the arthroscopic approach is a valuable tool if the surgeon aims to reduce the invasiveness of the procedure, with all the consequent advantages. LEVEL OF EVIDENCE IV: Retrospective case series, therapeutic study.

Unexpected tibial non-union after minimally invasive bridge plating: a case report.

A fit 42-year-old woman presented to our department with a closed isolated distal tibial and fibular shaft fracture (AO 42-B1.3), which was addressed with a minimally invasive plate osteosynthesis (MIPO) with a bridging technique for both the tibia and the fibula. No risk factors for healing issues were known at the time of surgery. At the 6-month follow-up, the leg was still painful during walking and the fracture site was still evident on the radiographs. Bone and CT-scans confirmed the diagnosis of oligotrophic non-union. A revision surgery was then successfully performed with a reamed IM tibial nail and a fibular osteotomy taking into consideration both biological and mechanical factors. Surgeons must treat tibial shaft fractures avoiding unnecessary damage to soft tissue, restoring an appropriate reduction of the bony segment and providing an adequate fixation; however, other factors may play a role in the development of "unexpected non-union".

Position of the prosthesis components in total ankle replacement and the effect on motion at the replaced joint.

PURPOSE: In some cases of total ankle replacement, perfect alignment of the prosthetic components is not achieved. This study analyses the extent to which component positioning is critical for the final range of motion. METHODS: Fourteen patients undergoing total ankle replacement were assessed preoperatively and postoperatively at seven and 13 months follow-up. X-ray pictures of the ankle were taken in static double leg stance, i.e. at neutral joint position, and in maximum plantarflexion and dorsiflexion. Measurements were obtained by a specially devised computer program based on anatomical reference points digitised on the radiograms. These allowed calculation of the position and orientation of the components in the sagittal and coronal planes, together with the joint range of motion. RESULTS: The mean range of motion was about 34 degrees at the first follow-up and maintained at the second. Tibial and talar components were more anterior than the mid-tibial shaft in 11 and nine patients, respectively. Mean inclination was about four degrees posterior for the tibial component and nearly one degree anterior for the talar component. A significantly larger range of motion was found in ankles both with the talar component located and inclined more anteriorly than the tibial. CONCLUSIONS: Correlation, though weak, was found between motion at the replaced ankle and possible residual subluxation and inclination of the components. However, a satisfactory range of motion was also achieved in those patients where recommended locations for the components could not be reached because of the size of the original joint deformity.

Biceps instability and Slap type II tear in overhead athletes.

Type II lesions are common lesions encountered in overhead athletes with controversies arising in term of timing for treatment, surgical approach, rehabilitation and functional results. The aim of our study was to evaluate the outcomes of arthroscopic repair of type II SLAP tears in overhead athletes, focusing on the time elapsed from diagnosis and treatment, time needed to return to sport, rate of return to sport and to previous level of performance, providing an overview concerning evidence for the effectiveness of different surgical approaches to type II SLAP tears in overhead athletes. A internet search on peer reviewed Journal from 1990, first descriprion of this pathology, to 2012, have been conducted evaluating the outcomes for both isolated Slap II tear overhead athletes and those who presented associated lesions treated. The results have been analyzed according to the scale reported focusing on return to sport and level of activity. Apart from a single study, non prospective level I and II studies were detected. Return to play at the same level ranged form 22% to 94% with different range of technique utilized with the majority of the authors recommending the fixation of these lesions but biceps tenodesis can lead to higher satisfaction racte when directly compated to the anchor fixation. Associated pathologies such as partial or full tickness rotator cuff tear did not clearly affect the outcomes and complications rate. There is no consensus regarding timing and treatment for type II SLAP, especially in overhead athletes who need to regain a high level of performance.
