Comparing midterm clinical outcome of surgical versus ultrasound guided needle aspiration of the calcific deposits for therapy resistant calcifying tendinitis of the shoulder. A comparative cohort study.

PURPOSE: Comparing the midterm clinical outcome of surgical treatment versus ultrasound guided needle aspiration of the calcific deposits (NACD) treatment for conservative therapy resistant calcifying tendinitis (CT) of the shoulder. The hypothesis is that both surgical treatment and NACD treatment led to a comparable good clinical outcome. METHODS: A comparative cohort study was performed (n = 76). The allocation to surgical group (n = 35) or NACD group (n = 41) was the result of a shared decision-making strategy. Primary outcome was decrease in VAS for pain (pVAS). Secondary outcomes were EQ-5D index, DASH score, ASES, VAS for satisfaction, recommendation of treatment, adverse events, cross-over between groups, additional treatments, and symptomatology after care as usual. RESULTS: At midterm follow-up (5.5 years, SD 0.5 years) decrease in pVAS did not differ (p = 0.20) between two groups (60.6 mm, SD 23.3 mm vs 53.4 mm, SD 24.2 mm). Secondary clinical outcomes were also comparable. In 68.3% surgical treatment was avoided. At final follow-up none of the outcome scores differed significantly between the crossed-over patients (n = 13, 31.7%) and the initial surgical group. DISCUSSION: At midterm follow-up surgical and NACD treatment result in comparable clinical outcomes. In 68.3% a surgical treatment could be avoided. In 31.7% the patient eventually needed a surgical treatment after failed NACD treatment. After midterm follow-up these patients showed comparable good clinical outcomes. In our opinion, both NACD and surgical treatment could be considered as a next step treatment option for conservative therapy resistant CT of the shoulder. Though, one should be aware that after a midterm follow-up a high number of patients cross-over to surgical treatment after a NACD treatment.

Comparable clinical and radiographical outcomes between second and third generation of gamma nails.

The aim of the study is to compare the overall complication rate and in particular lag screw cut-out between the Trochanteric Gamma Nail and the Gamma 3 Nail. A total of 294 implants (Trochanteric Gamma Nail= 132 and Gamma 3 Nail=163) in 291 patients were analysed. All clinical data was obtained from the patients medical records. Subsequently radiographs were evaluated for fracture type according to the AO classification and lag screw position by determining the tip-apex distance, the Parker's ratio and the neck- shaft-angle. No significant differences in complication rates were found. The Parker's ratio was associated with lag screw cut-out : patients with medial cut-out had more a posteriorly placement (n=9, 3.1%), while patients with cranial cut-out had a more cranial placement of the lag screw (n=10, 3.4%). The tip-apex-distance and neck-shaft-angle were not associated with cut-out. The complication rate of the Gamma 3 Nail does not differ from the Trochanteric Gamma Nail. A lag screw positioning central or slightly inferior on the anteroposterior view and central on the lateral view is recommended.

The Role of Dynamic Contrast-Enhanced MRI in a Child with Sport-Induced Avascular Necrosis of the Scaphoid: A Case Report and Literature Review.

Avascular necrosis (AVN) of the scaphoid in children is very rare and there is currently no consensus when conservative or operative treatment is indicated. A 10-year-old boy, practicing karate, presented with acute pain in his left wrist after falling on the outstretched hand. Imaging showed a scaphoid waist fracture with signs of an ongoing AVN. The diagnosis of AVN was confirmed with signal loss of the scaphoid on MRI T1. A dynamic contrast-enhanced MRI was performed for further assessment of the proximal pole vascularity and treatment planning. As dynamic contrast-enhanced MRI showed fair perfusion of the proximal pole, an adequate healing potential with conservative treatment was estimated. We achieved union and good function with cast immobilization for fourteen weeks. This case study showed dynamic contrast-enhanced MRI to be a valuable tool in assessing whether conservative or operative treatment is indicated to achieve union and good functional outcome.

Long-term Follow-up of a Randomized Controlled Trial Comparing Scarf to Chevron Osteotomy in Hallux Valgus Correction.

BACKGROUND: Hallux valgus is one of the most common foot deformities. This long-term follow-up study compared the results of 2 widely used operative treatments for hallux valgus: the scarf and chevron osteotomy. METHODS: Conventional weight bearing anteroposterior (AP) radiographs of the foot were made for evaluating the intermetatarsal angle and hallux valgus angle. For clinical evaluation, the American Orthopaedic Foot & Ankle Society (AOFAS) rating system for the hallux metatarsophalangeal-interphalangeal scale was used together with physical examination of the foot. These data were compared with the results from the original study. The Short Form 36 questionnaire, the Manchester-Oxford Foot Questionnaire (MOXFQ), and a general questionnaire including a visual analog scale (VAS) pain score were used for subjective evaluation. The primary outcome measures were the radiologic recurrence of hallux valgus and reoperation rate of the same toe. Secondary outcome measures were the results from the radiographs and subjective and clinical evaluation. The response rate was 76% at the follow-up of 14 years; in the chevron group, 37 feet were included compared with 36 feet in the scarf group. RESULTS: Twenty-eight feet in the chevron group and 27 in the scarf group developed recurrence of hallux valgus (P = .483). One patient in the scarf group had a reoperation of the same toe compared with none in the chevron group (P = .314). Current VAS pain scores and results from the SF-36, MOXFQ, and AOFAS did not significantly differ between groups. CONCLUSION: Both techniques showed similar results after 2 years of follow-up. At 14 years of follow-up, neither technique was superior in preventing recurrence. LEVEL OF EVIDENCE: Level II, randomized controlled trial.

Intra-articular plica causing ankle impingement in a young handball player: a case report.

Ankle sprains are common injuries that respond well to rehabilitation. In the case of persisting symptoms, the differential diagnosis should include osteochondral defects, tendon injury, mechanical instability, and ankle impingement. In the present case report, we describe a 16-year-old male handball player who presented with persisting pain and locking in the right ankle 3 years after having sustained multiple minor inversion trauma. The clinical examination and conventional radiography showed no abnormalities. On magnetic resonance imaging, a flake fracture at the anteromedial talar dome and/or loose body was assumed. Arthroscopic examination revealed an intra-articular plica originating from an osteochondral fossa at the anteromedial tibial plafond. The plica was debrided. Retrospectively, the arthroscopic findings matched the radiographs and magnetic resonance images. The postoperative protocol consisted of early mobilization. At 6 weeks of follow-up, the patient had no pain and had returned to his sports activities. The present case report illustrates, to the best of our knowledge, the first case of ankle impingement due to a, most likely congenital, intra-articular plica arising from an osteochondral fossa at the anteromedial tibial plafond. This rare clinical condition can be diagnosed with magnetic resonance imaging. Arthroscopic debridement will effectively relieve the symptoms.
