Surgical approaches to the capitellum: a comparative anatomic study.

BACKGROUND: Osteochondritis dissecans (OCD) of the humeral capitellum is an important cause of elbow disability in young athletes. Large and unstable lesions sometimes require joint reconstruction with osteochondral autograft. Several approaches have been described to expose the capitellum for the purpose of treating OCD. The posterior anconeus-splitting approach and the lateral approach with or without release of the lateral ligamentous complex are the most frequently used for this indication. The surface accessible by these approaches has not been widely studied. This study compared the extent of the articular surface of the capitellum that could be exposed with the Kocher approach (without ligament release) vs. the posterior anconeus-splitting approach. A secondary outcome was the measurement of any additional area that could be reached with lateral ulnar collateral ligament release (Wrightington approach). METHODS: The 3 approaches were performed on 8 adult cadaveric elbows: first, the Kocher approach; then, the anconeus-splitting approach; and finally, the Wrightington approach. The visible articular surface was marked out after completion of each approach. RESULTS: The mean articular surface of the capitellum was 708 mm2 (range, 573-830 mm2). The mean visible articular surface was 49% (range, 43%-60%) of the total surface with the Kocher approach, 74% (range, 61%-90%) with the posterior anconeus-splitting approach, and 93% (range, 91%-97%) with the Wrightington approach. Although the Kocher approach provided access to the anterior part of the capitellum, the anconeus-splitting approach showed adequate exposure to the posterior three-quarters of the articular surface and overlapped the most posterior part of the Kocher approach. A combination of the 2 lateral ulnar collateral ligament-preserving approaches allowed access to 100% of the joint surface. CONCLUSION: Most OCD lesions are located in the posterior area of the capitellum and can therefore be reached with the anconeus-splitting approach. When OCD lesions are located anteriorly, the Kocher approach without ligament release is efficient. A combination of these 2 approaches enabled the entirety of the joint surface to be viewed.

Fusion rate of 89% after knee arthrodesis using an intramedullary nail: a mono-centric retrospective review of 48 cases.

PURPOSE: Knee arthrodesis is an established procedure for limb salvage in cases of recurrent infection, total knee arthroplasty soft tissue defect, poor bone stock or a deficient extensor mechanism. Surgical options include compression plate, external fixator and arthrodesis nail. Different types of nail exist: long fusion nail, short modular nail and bridging nail. This study presents the results on knee arthrodesis using different types of intramedullary nails. The aim is to assess if a specific type of nail has a better fusion rate, clinical outcome and lower complication rate. METHODS: A mono-centric retrospective study of 48 knees arthrodesis was performed between 2000 and 2018. 15 T2™ Arthrodesis Nail, 6 OsteoBridge® Knee Arthrodesis and 27 Wichita® fusion nail were used. The mean clinic and radiological follow-up was 9.8 ± 3.8 years (2.6-18 years). RESULTS: Fusion rate was 89.6%. Time to fusion was 6.9 months. Mean Parker score was 6.9/9 points. Visual Analogic Scale was 1.9. The Wichita® fusion nail showed better results in terms of fusion, time to fusion and clinical outcome measured by Parker score and VAS but without statistical significance. The early revision rate was 10.4% and 20.8% presented a late complication requiring a surgery, due to nonunion or infection. 93.3% of infection was cured. Two patients live with a fistula (4.2%) and 1 was amputated (2.1%). CONCLUSION: Although burdened by a big complication rate, knee arthrodesis with an intramedullary nail provides satisfactory results and is a good alternative to above-knee-amputation. The Wichita® fusion nail shows a tendency to better results compared to the two other nails. LEVEL OF EVIDENCE: Case series, level IV.

Image-guided percutaneous cryoablation of unresectable sacrococcygeal chordoma: Feasibility and outcome in a selected group of patients with long term follow-up.

BACKGROUND: Chordoma is a rare malignant tumor of the axial skeleton. Percutaneous cryoablation (PCA) is a minimally invasive technique that allows freezing of tumors under imaging control. The purpose of our retrospective study was to investigate the outcome of PCA in a selected cohort of patients with sacrococcygeal chordoma, with a minimum of 5 years follow-up. MATERIALS AND METHODS: Four patients were treated in 10 sessions. The mean follow-up was 57.3 months. We evaluated the feasibility, the procedure-related complications, the impact on pain control and oncological outcomes. RESULTS: Freezing of 100% of the tumor volume was possible in 60%. Pain control was not reliably evaluable. Local recurrence occurred in 90% of the treated lesions; the mean time to progression was 8.1 months (range 1.5-16). At last follow-up, one patient had died of the disease, one of another cause and one was receiving the best supportive care. The only patient alive without the disease had received additional carbon-ion radiotherapy. The 5-year survival rate after index PCA was 50%. CONCLUSION: Complete freezing of the tumor was technically challenging, mainly due to the complex local anatomy. Recurrence occurred in 90% of the lesions treated. PCA should be considered with caution in the curative management of sacrococcygeal chordoma.

Subcutaneous tissue disinfection significantly reduces Cutibacterium acnes burden in primary open shoulder surgery.

BACKGROUND: Cutibacterium acnes is one of the major pathogens responsible for infection after shoulder surgery. Surgical dissection of the dermis may expose C acnes from sebum-producing hair follicles. Because of contact with the surgeon's gloves and instruments, further spread occurs throughout the surgical field. The purpose of this study was to determine whether subcutaneous tissue disinfection could reduce the C acnes culture rate in primary open shoulder surgery. METHODS: All patients eligible for primary open shoulder surgery by a deltopectoral approach were prospectively enrolled in our 2-arm, randomized, single-blinded clinical trial. In all patients, a skin swab of the operative field was taken prior to standard surgical skin preparation. After exposure of the deltoid fascia, the disinfection group received an additional preparation of the subcutaneous layer with povidone-iodine solution. Once the proximal humerus was completely exposed, 5 swabs from different sites were taken for microbiological examination according to a strict specimen collection protocol. All cultures were incubated in aerobic and anaerobic conditions for 14 days. RESULTS: Between February and December 2019, 108 patients were enrolled in the 2 groups: treatment (n = 70) and control (n = 38). The 2 groups did not show any significant difference in terms of sex, age, body mass index, or occurrence of diabetes. The subcutaneous disinfection protocol significantly reduced the positive culture rate of the operating field for all germs combined (P = .036) and specifically for C acnes (P = .013). The reduction of positive swabs for C acnes was significant for the surgeon's gloves (P = .041), as well as the retractors (P = .007). CONCLUSION: Disinfection of the subcutaneous tissue significantly reduced the C acnes culture rate during primary open shoulder surgery. We highly recommend this simple step as an adjunct to the current surgical practice to limit iatrogenic contamination of the surgical field. Future studies may observe a reduction in postoperative shoulder infection owing to this practice.

[Update on humeral shaft fractures]. / Mise au point sur les fractures diaphysaires de l'humérus.

Humeral shaft fractures are relatively common, representing up to 5% of all fractures. Conservative management is the treatment of choice for most humeral shaft fractures and offers good functional and union outcomes. Age and oblique fractures of the proximal third are two risk factors for non-union. Surgical indication threshold should be lower for patients with these factors. Functional outcomes and union rates after plating and intramedullary nailing are comparable, but the likelihood of shoulder complications is higher with intramedullary nailing. Finally, there is no advantage to early exploration of the radial nerve even in case of secondary radial nerve palsy.

Les fractures de la diaphyse humérale sont relativement fréquentes et représentent jusqu'à 5 % des fractures. Le traitement conservateur par brace est le traitement de choix pour la majorité des fractures. Il permet un taux élevé de consolidation et est associé à de bons résultats fonctionnels. L'âge ainsi que les fractures obliques du tiers proximal sont deux facteurs de risque de pseudarthrose en présence desquels une prise en charge chirurgicale doit être plus facilement envisagée. Lorsqu'ils sont indiqués, l'ostéosynthèse par plaque et l'enclouage centromédullaire offrent des taux de consolidation et des résultats fonctionnels équivalents, avec cependant un risque de problème d'épaule plus important après enclouage. Finalement, l'exploration chirurgicale immédiate du nerf radial n'est pas recommandée, même en cas de parésie secondaire à la réduction de la fracture.

Total clavicle reconstruction with free peroneal graft for the surgical management of chronic nonbacterial osteomyelitis of the clavicle: a case report.

BACKGROUND: Chronic nonbacterial osteomyelitis (CNO) is a rare chronic autoinflammatory syndrome affecting mainly children and young adults. The natural history of the disease is marked by recurrent pain as the mainstay of inflammatory outbreaks. Typical radiographic findings are osteosclerosis and hyperostosis of the medial clavicle, sternum and first rib. Compression of the brachial plexus is exceedingly rare and one of the few surgical indications. Literature on total clavicle reconstruction is scarce. While claviclectomy alone has been associated with fair functional and cosmetic outcomes, several reconstruction techniques with autograft, allograft or even cement ("Oklahoma prosthesis") have been reported with the aim of achieving better pain control, cosmetic outcome and protecting the brachial plexus and subclavian vessels. We herewith report a unique case of complicated CNO of the clavicle treated with total clavicle reconstruction using a free peroneal graft. CASE PRESENTATION: A 21-year-old female patient presented with CNO of her left clavicle, associated with recurrent, progressive and debilitating pain as well as limited range of motion. In recent years, she started complaining of paresthesia, weakness and pain radiating to her left arm during arm abduction. The clavicle diameter reached 6 cm on computed tomography, with direct compression of the brachial plexus and subclavian vessels. Following surgical biopsy for diagnosis confirmation, she further developed a chronic cutaneous fistula. Therefore, a two-stage total clavicle reconstruction using a vascularized peroneal graft stabilized by ligamentous reconstruction was performed. At two-year follow-up, complete pain relief and improvement of her left shoulder Constant-Murley score were observed, along with satisfactory cosmetic outcome. CONCLUSIONS: This case illustrates a rarely described complication of CNO with direct compression of the brachial plexus and subclavian vessels, and chronic cutaneous fistula. To our knowledge, there is no consensus regarding the optimal management of this rare condition in this context. Advantages and complications of clavicle reconstruction should be carefully discussed with patients due to limited evidence of superior clinical outcome and potential local and donor-site complications. While in our case the outcomes met the patient's satisfaction, it remains an isolated case and further reports are awaited to help surgeons and patients in their decision process.

[Surgical treatment of proximal femur metastases]. / Traitement chirurgical des métastases du fémur proximal.

Aging of the population results in an increase of the incidence of cancer and bone metastases. The proximal femur is one of the most frequent locations of bone metastases. A pathological fracture has a major impact on the quality of life and potentially on survival. In case of impending fracture, prophylactic fixation is therefore strongly recommended. The management of metastases of the proximal femur depends on multiple parameters, life expectancy and fracture risk being the most important ones. If survival is estimated to be less than 6 weeks, surgery is generally not indicated. Beyond 6 weeks, surgical indication essentially depends on location of the metastases on the proximal femur and the presence of a fracture.

L'augmentation de l'espérance de vie s'accompagne d'une croissance de l'incidence des cancers et des métastases osseuses. Le fémur proximal est un des sites les plus fréquents de métastases osseuses. Une fracture pathologique dans cette localisation a un impact majeur sur la qualité de vie et potentiellement sur la survie du patient. Un traitement chirurgical prophylactique est ainsi recommandé en cas de risque de fracture imminente. La prise en charge des métastases fémorales proximales se décide en fonction de multiples paramètres, dont la survie théorique et le risque de fracture sont les plus importants. Si la survie est estimée à moins de 6 semaines, une chirurgie n'est en général pas indiquée. Au-delà, l'indication chirurgicale dépend essentiellement de la localisation des lésions et de la présence d'une fracture associée.

Knee arthrodesis with modular nail after failed TKA due to infection.

INTRODUCTION: Knee arthrodesis is an established procedure for limb salvage after failed total knee arthroplasty (TKA) in cases of recurrent infection, soft tissue damage, reduced bone stock or with a deficient extensor mechanism. Walking with an arthrodesis is more efficient and less costly in terms of energy expenditure than above-knee amputation. Surgical options include an arthrodesis nail, external fixator or compression plate. We present our results of knee arthrodesis using the modular Wichita Fusion Nail(®) in patients after infected TKA. METHODS: Fifteen patients with irretrievably failed TKA, due to infection, who underwent arthrodesis with the Wichita Fusion Nail(®) from 2004 to 2012 were retrospectively reviewed to assess fusion rate, time to fusion, complication rate, including new infections, and ambulatory status. RESULTS: Three patients were lost to follow-up. Mean follow-up was 33 months (6-132 months). At their most recent follow-up, all patients were walking with full weight bearing on a fused arthrodesis. Mean time to union was 9 months (3-29 months). Three patients necessitated a revision arthrodesis to achieve union after a mean of 5 months after the last procedure. CONCLUSION: Arthrodesis with the Wichita Fusion Nail(®) provides satisfactory results in patients with failure after infected TKA, with 75 % primary union rate and no new or persistent infection at last follow-up visit. Although burdened with a high complication rate, it represents an acceptable option for limb salvage in this particular pathology.

Metaphyseal tibial level (MTL) screws: a modified percutaneous technique for lateral plateau depression fractures.

INTRODUCTION: Lateral tibial plateau fractures are more frequent than medial fractures, and those with articular depression are particularly challenging because of high displacement risk. To prevent secondary subsidence, the gold standard is raft screws with a periarticular or anti-glide plate. Graft is used to fill the metaphyseal defect created by reduction in the depressed fragment. We present a case of Schatzker II fracture managed in a complete percutaneous fashion, with a new combined technique of raft screws and interference screw used as a support. CASE REPORT: A 51-year-old female sustained a Schatzker II tibial plateau fracture. Based on pre-operative CT, direction of reduction force to apply was drawn on coronal and sagittal cuts. OPERATIVE TECHNIQUE: Under fluoroscopic control, the split component of the fracture was reduced. The cortical window was then drilled in the lateral cortex, and a K wire advanced under the depressed fragment under fluoroscopic guidance. After fragment reduction with a bone impacter, internal fixation was completed by percutaneous introduction of two subchondral cortical screws. A bioabsorbable interference screw was then introduced in the impacter tunnel to support impacted bone under the reduced articular surface. Finally, a cortical screw was introduced, from anterior to posterior to prevent screw cut-out. CONCLUSION: The combination of subchondral screws in a jail technique with a bioabsorbable interference screw that we named metaphyseal tibia level (MTL) screw technique is, to our knowledge, not described. The MTL screw promises to be a true percutaneous reduction and fixation technique for Schatzker II and III fractures in patients with reasonable bone quality.

Functional and Radiologic Outcomes of Degenerative Versus Traumatic Full-Thickness Rotator Cuff Tears Involving the Supraspinatus Tendon.

BACKGROUND: Arthroscopic rotator cuff repair (ARCR) is among the most commonly performed orthopaedic procedures. Several factors-including age, sex, and tear severity-have been identified as predictors for outcome after repair. The influence of the tear etiology on functional and structural outcome remains controversial. PURPOSE: To investigate the influence of tear etiology (degenerative vs traumatic) on functional and structural outcomes in patients with supraspinatus tendon tears. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Patients undergoing ARCR from 19 centers were prospectively enrolled between June 2020 and November 2021. Full-thickness, nonmassive tears involving the supraspinatus tendon were included. Tears were classified as degenerative (chronic shoulder pain, no history of trauma) or traumatic (acute, traumatic onset, no previous shoulder pain). Range of motion, strength, the Subjective Shoulder Value, the Oxford Shoulder Score (OSS), and the Constant-Murley Score (CMS) were assessed before (baseline) and 6 and 12 months after ARCR. The Subjective Shoulder Value and the OSS were also determined at the 24-month follow-up. Repair integrity after 12 months was documented, as well as additional surgeries up to the 24-month follow-up. Tear groups were compared using mixed models adjusted for potential confounding effects. RESULTS: From a cohort of 973 consecutive patients, 421 patients (degenerative tear, n = 230; traumatic tear, n = 191) met the inclusion criteria. The traumatic tear group had lower mean baseline OSS and CMS scores but significantly greater score changes 12 months after ARCR (OSS, 18 [SD, 8]; CMS, 34 [SD,18] vs degenerative: OSS, 15 [SD, 8]; CMS, 22 [SD, 15]) (P < .001) and significantly higher 12-month overall scores (OSS, 44 [SD, 5]; CMS, 79 [SD, 9] vs degenerative: OSS, 42 [SD, 7]; CMS, 76 [SD, 12]) (P≤ .006). At the 24-month follow-up, neither the OSS (degenerative, 44 [SD, 6]; traumatic, 45 [SD, 6]; P = .346) nor the rates of repair failure (degenerative, 14 [6.1%]; traumatic 12 [6.3%]; P = .934) and additional surgeries (7 [3%]; 7 [3.7%]; P = .723) differed between groups. CONCLUSION: Patients with degenerative and traumatic full-thickness supraspinatus tendon tears who had ARCR show satisfactory short-term functional results. Although patients with traumatic tears have lower baseline functional scores, they rehabilitate over time and show comparable clinical results 1 year after ARCR. Similarly, degenerative and traumatic rotator cuff tears show comparable structural outcomes, which suggests that degenerated tendons retain healing potential.

Skiing and snowboarding related deep laceration injuries. A five-season cross-sectional analysis from a level-1 trauma centre in the Swiss Alps.

OBJECTIVES: Lacerations comprise 5.6-33.6% of skiing/snowboarding related injuries. This study aimed to investigate the mechanism of injury and the location of these lacerations and propose preventive measures. METHODS: After our state ethics committee approval, we retrospectively reviewed the medical records and surgical protocols of 46 patients (mean age (±SD) 34.6 (±15.3); 71.4% men) treated for severe skiing/snowboarding lacerations at our level-1 trauma centre between 2016 and 2021. Patients were asked to answer a questionnaire on their skiing experience, equipment used and the circumstances of the accident. RESULTS: Lacerations around the hip, thigh, and knee accounted for 94%. The latter was the most common location (45%). Although 91.3% of patients wore appropriate clothing and full standard protection equipment, it did not offer any extra-resistance against skiing/snowboarding's edges. Skiers were more affected (91.3%) than snowboarders (8.7%). The most common mechanism of injury was inadvertent release of the bindings (52.2%), followed by insufficient ski level for the slope (21.7%) and collisions (17.4%). Long-term trends demonstrated an increasing incidence. CONCLUSION: Identification of body areas at risk and the mechanisms of injury were the most significant findings of this work. These data encourage the development of specific injury prevention programs as the occurrence of these lesions tended to increase over the last few years. To reduce their incidence, we propose skiers to have their bindings regularly adjusted and manufacturers to develop cut-resistant skiwear. LEVEL OF EVIDENCE: IV.

Humeral shaft fractures.

Humeral shaft fractures are relatively common, representing approximately 1% to 5% of all fractures.Conservative management is the treatment of choice for most humeral shaft fractures and offers functional results and union rates that are not inferior to surgical management.Age and oblique fractures of the proximal third are risk factors for nonunion. Surgical indication threshold should be lower in patients older than 55 years presenting with this type of fracture.Functional outcomes and union rates after plating and intramedullary nailing are comparable, but the likelihood of shoulder complications is higher with intramedullary nailing.There is no advantage to early exploration of the radial nerve even in secondary radial nerve palsy.

Unrecognized Chondrosarcoma as a Cause of Total Hip Arthroplasty Failure.

BACKGROUND: Total hip arthroplasty (THA) is one of the most successful procedures in orthopedic surgery. The most frequent THA indications are osteoarthritis and avascular necrosis, whereas symptomatic aseptic loosening is the most common indication to revision surgery. Chondrosarcoma (CS) is the most frequent bone sarcoma in adults, and proximal femur is the most prevalent location. Wide resection is the treatment of choice.We report 3 cases of unrecognized high-grade CS in the setting of primary or revision THA and reviewed the literature on this rare clinical presentation. METHODS: A systematic literature review on CS in the setting of THA, published between 1980 and 2020, was performed on PubMed, Embase, Medline, Ovid SP, and Web of Science, using the guidelines set in the Preferred Reporting Items for Systematic Reviews and Mata-analyses (PRISMA). RESULTS: Case series: Three patients were referred to our sarcoma center after failure of THA due to unrecognized high-grade CS. All 3 had rapid fatal outcome. Literature review: Fifty-nine articles were identified, of which 8 were included in the study. They confirmed that primary or revision THA failure due to unrecognized CS is extremely rare, with only few cases reported in the literature. CONCLUSIONS: Before proceeding to primary or revision arthroplasty, diagnosis must be ascertained. Atypical presentation of a common pathology, such as osteoarthritis, avascular necrosis, or aseptic loosening of an endoprosthesis, should raise suspicion for another cause to symptoms, and additional workup be performed. As our cases demonstrated, unrecognized or inadequately managed bone sarcoma may lead to poor or even fatal outcome.

Agenesis of the long head of the biceps brachii tendon: ignored variations of the anatomy and the next tendon to disappear?

Bilateral agenesis of the long head of the biceps brachial tendon (LHB) is a very rare variation of the anatomy. We report a case of an 18-year-old man with bilateral agenesis of the long head of the biceps brachii tendon. We present initial findings, radiographical examinations and the follow-up of an unusual entity. Diagnosis of agenesis of the LHB can be challenging especially in cases of traumatic shoulder pain. It is not a very known entity because of its rareness. However, it could be associated with other congenital anomalies. The absence of the LHB is easily ignored in the diagnostic process. Clinical examination should be a pitfall, radiological examination is helpful to confirm the suspicion of LHB absence. MRI is often the first choice, although ultrasonography is cheaper and much easier to access and it is an excellent tool to visualise this anatomic variation with empty or shallow intertubercular groove.

Predrilled locking compression plate is more accurate than tension band wiring in restoring articular geometry of the ulnar greater sigmoid notch after olecranon Chevron osteotomy.

INTRODUCTION: The olecranon Chevron osteotomy (OCO) is commonly used to approach complex intra-articular fractures of the distal humerus. Predrilled tension band wiring (TBW) has historically been used to fix OCO. However, clinical outcomes are burdened by secondary loss of reduction and up to 21.3% non-union rates. The biomechanical stability of anatomic locking compression plate (LCP) was reported to be superior to TBW in olecranon fracture fixation. We hypothesised that this implant may also be superior to TBW in the anatomic reconstruction of the articular surfaces of the ulnar greater sigmoid notch after OCO by predrilling the holes of the angular stable plate with the threaded drill guide prior to osteotomy. MATERIALS AND METHODS: Lateral standardised and calibrated radiographs of twenty synthetic ulnar bones were obtained using a custom-made holder prior to preparation by a senior orthopaedic trauma surgeon. Ten specimens were then predrilled using the threaded drill bit guide of an olecranon LCP, while the other ten samples were predrilled with two 1.6 mm Kirschner wires. A distal "V" OCO was performed using a 0.6 mm oscillating saw. After repositioning and fixation with the corresponding device, lateral radiographs were repeated. Two independent observers used the TraumaCad planning software to document the articular geometry of the ulnar greater sigmoid notch pre- and postoperatively. The diameter of the best-fitting circle (diameter), the distance between the tip of the coronoid and the olecranon processes (distance) and the maximum articular depth were measured. RESULTS: With the TBW technique, after OCO and fixation, all three postoperative measurements were significantly (p≤0.001) different from preoperative measurements. The diameter and distance increased by a mean of 1.5±0.5 mm and 0.9±0.3 mm, respectively, while the depth decreased by a mean of 0.2±0.1 mm. In contrast, no significant differences between pre- and postoperative measurements were observed with the LCP technique (p≥0.13). Inter and intra-observer measurement reliability was strong to very strong (intraclass correlation coefficients≥0.793) for all three variables. CONCLUSION: Our study reveals that the predrilled LCP technique is more accurate than the predrilled TBW in restoring the anatomic articular geometry of the ulnar greater sigmoid notch after OCO.

Cryoablation of Extra-Abdominal Desmoid Tumors: A Single-Center Experience with Literature Review.

Cryoablation (CA) has gained popularity in the treatment of benign and malignant musculoskeletal tumors. While extra-abdominal desmoid (EAD) tumors are not malignant, they remain challenging to treat because of their high local recurrence rate. We reviewed all EAD tumors treated with CA at our institution between November 2012 and March 2020. Fourteen procedures were performed on nine females and one male (mean age, 33 ± 18 years) as either first-line (n = 4) or salvage therapy (n = 6) with curative intent (n = 8) or tumor debulking (n = 2). Mean tumor size was 63.6 cm3 (range, 3.4-169 cm3). Contrast-enhanced MRI was performed before treatment and at 3-, 6-, and 12-month follow-up. Treatment outcome was based on the change in enhanced tumor volume (ET-V). For curatively treated patients, the mean ET-V change was -97 ± 7%, -44 ± 143%, and +103 ± 312% at 3, 6, and 12 months, respectively. For debulking patients, the mean ET-V change was -98 ± 4%, +149 ± 364%, and +192 ± 353% at 3, 6, and 12 months, respectively. During a mean follow-up of 53.7 months (range, 12-83 months), one grade III and one grade IV complication were noted. We found CA to be safe and well tolerated in patients with EAD.

Technique Tip: Platysma-flap Approach to the Clavicle.

The surgical treatment of a displaced fracture of the clavicular shaft generally consists in an open reduction and plate fixation. The most common complications of the classic direct "transplatysma" approach are hardware related. These consist of simple hardware irritations requiring secondary plate removal but also feared wound healing problems ranging from dehiscence to superficial and deep wound infections. In the present article, we describe the so-called "platysma-flap" approach in which the platysma muscle is entirely preserved and distally raised as a flap. This modified exposure allows to cover the osteosynthesis with a viable, well perfused soft tissue envelope and is a safe alternative to the standard "transplatysma" approach.

Advanced septic arthritis of the shoulder treated by a two-stage arthroplasty.

BACKGROUND: The usual treatment of septic shoulder arthritis consists of arthroscopic or open lavage and debridement. However, in patients with advanced osteoarthritic changes and/or massive rotator cuff tendon tears, infection eradication can be challenging to achieve and the functional outcome is often not satisfying even after successful infection eradication. In such cases a two-stage approach with initial resection of the native infected articular surfaces, implantation of a cement spacer before final treatment with a total shoulder arthroplasty in a second stage is gaining popularity in recent years with the data in literature however being still limited. AIM: To evaluate the results of a short interval two-stage arthroplasty approach for septic arthritis with concomitant advanced degenerative changes of the shoulder joint. METHODS: We retrospectively included five consecutive patients over a five-year period and evaluated the therapeutic management and the clinical outcome assessed by disability of the arm, shoulder and hand (DASH) score and subjective shoulder value (SSV). All procedures were performed through a deltopectoral approach and consisted in a debridement and synovectomy, articular surface resection and insertion of a custom made antibiotic enriched cement spacer. Shoulder arthroplasty was performed in a second stage. RESULTS: Mean age was 61 years (range, 47-70 years). Four patients had previous surgeries ahead of the septic arthritis. All patients had a surgical debridement ahead of the index procedure. Mean follow-up was 13 mo (range, 6-24 mo). Persistent microbiological infection was confirmed in all five cases at the time of the first stage of the procedure. The shoulder arthroplasties were performed 6 to 12 wk after insertion of the antibiotic-loaded spacer. There were two hemi and three reverse shoulder arthroplasties. Infection was successfully eradicated in all patients. The clinical outcome was satisfactory with a mean DASH score and SSV of 18.4 points and 70% respectively. CONCLUSION: Short interval two-stage approach for septic shoulder arthritis is an effective treatment option. It should nonetheless be reserved for selected patients with advanced disease in which lavage and debridement have failed.

Percutaneous image-guided cryoablation of painful bone metastases: A single institution experience.

BACKGROUND: Bone metastases are frequently painful and may lead to various complications that can affect quality of life. While external beam radiation therapy is the standard first-line treatment, 20-30% of patients do not experience sufficient pain relief. Cryoablation is increasingly being used for the treatment of musculoskeletal metastases. The purpose of our retrospective study was to analyze pain relief and local disease control after percutaneous image-guided cryoablation (PCA) therapy of painful bone metastases. MATERIALS AND METHODS: Sixteen patients treated with PCA for painful bone metastases (n=18) over a 5-year period (from June 2011 to June 2016) were retrospectively reviewed. Five patients also benefited from long bone fixation because of an impending fracture. We analyzed the impact of treatment on pain relief, using a numerical rating scale (NRS), and local disease control. RESULTS: The mean follow-up period was 12 months (range, 1.5-39 months). At last oncological outpatient consultation, 75% (12/16) of patients had good pain relief, while 63% (10/16) had locally stable disease or no local recurrence of the treated bone metastases. The mean NRS score decreased significantly from 3.3 to 1.2 after PCA (p=0.0024). The five patients with concomitant long bone fixation all had satisfactory pain relief at the last follow-up visit. CONCLUSION: PCA is a safe and valid treatment option for pain and local disease control in cases of painful bone metastases after failed standard first-line therapy. This technique can also be effectively associated to prophylactic long bone fixation and may allow for easier rehabilitation protocols when treating weight-bearing bones.
