Comparison of different interposition techniques after surgical resection of tarsal coalitions in children: a systematic review.

In the surgical treatment of tarsal coalitions, it is unclear whether interposition material should be used to prevent recurrence. The aim of this review was to systematically examine the results of different interposition tissues after surgical resection of tarsal coalitions in children. A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent investigators systematically searched electronic databases (PubMed, Embase, Cochrane) and included original articles reporting outcomes of tarsal coalition resection. The quality of included studies was assessed using the Methodological Index for Non-Randomized Studies (MINORS) criteria. Out of 294 articles, 21 studies examining 436 patients (581 feet), were included. The mean age was 12.2 years (range 7-18). There were 153 talocalcaneal, 425 calcaneonavicular, 2 naviculocuboidal, and 1 naviculocuneiform coalitions. The mean follow-up time was 58 months (range 12-276). In 96 feet, solely resection was performed. Resection and interposition were performed with muscle/tendon (n = 178), fat graft (n = 176), other material (n = 36), or a combination of interposition techniques (n = 95). Eighteen studies reported on recurrence, which was found in 45 of 485 feet (9%). The highest recurrence (17%) was described after muscle/tendon interposition for calcaneonavicular coalitions. However, a statistical comparison could not be performed. The included studies were diverse and the scientific quality was generally low (MINORS mean 7, range 3-20). Coalition resection with various interposition techniques results in low recurrence rates. It is unclear which interposition material shows the best results.

Three weeks of indomethacin is not superior to 1 week of meloxicam as prophylaxis for heterotopic ossifications after distal biceps tendon repair with a single-incision technique.

BACKGROUND: The aim of this study was to assess the efficacy of 3 weeks of indomethacin, a nonselective nonsteroidal anti-inflammatory drug, in comparison to 1 week of meloxicam as prophylaxis for heterotopic ossifications (HOs) after distal biceps tendon repair. METHODS: A single-center retrospective study was performed on 78 patients undergoing distal biceps tendon repair between 2008 and 2019. From 2008 to 2016, patients received meloxicam 15 mg daily for the period of 1 week as usual care. From 2016 onward, the standard protocol was changed to indomethacin 25 mg 3 times daily for 3 weeks. All patients underwent a single-incision repair with a cortical button technique. The postoperative rehabilitation protocol was similar for all patients. The postoperative radiographs at 8-week follow-up were assessed blindly by 7 independent assessors. If HOs were present, it was classified according to the Ilahi-Gabel classification for size and according to the Gärtner-Heyer classification for density. Statistical analysis was performed to analyze the difference in HO between the patients who were treated with indomethacin and with meloxicam. RESULTS: Seventy-eight patients, with a mean age of 48.8 years (range 30-72) were included. The mean follow-up after surgery was 12 months (range 2-45). Indomethacin (21 days, 25 mg 3 times per day) was prescribed to 26 (33%) patients. The 52 other patients (67%) were prescribed meloxicam 15 mg daily for 7 days. HOs were seen in 19 patients 8 weeks postoperatively. Five of 26 patients treated with indomethacin developed HO, and 14 of 52 patients treated with meloxicam developed HO (P = .5). Two patients had symptomatic HO with minor restrictions in movement; neither patient was treated with indomethacin. Significantly more HOs were seen in patients with a longer time from injury to surgery (P = .01) The intraclass correlation score for reliability between assessors for HO scoring on postoperative radiographs was good to excellent for both classifications. CONCLUSION: In this study, HOs were seen in 24% of postoperative radiographs. Three weeks of indomethacin was not superior to meloxicam for 1 week for the prevention of HO after single-incision distal biceps tendon repair.

Developments in diagnosis and treatment of paediatric septic arthritis.

Acute septic arthritis in children is an orthopaedic emergency. A delay in diagnosis and inappropriate treatment can result in devastating damage to the joint with lifelong disability as a consequence. The clinical presentation can be a diagnostic challenge, especially in young children. A recent systematic review showed that joint tenderness and fever are important signals of septic arthritis. Ultrasound is helpful in detecting the presence of a joint effusion. Plain radiographs may show bone changes but magnetic resonance imaging is the most reliable imaging study for detecting concomitant osteomyelitis. The diagnosis of acute septic arthritis is highly suggestive when pus is aspirated from the joint, in case of a positive culture or a positive gram stain of the joint fluid, or if there is a white blood-cell count in the joint fluid of more than 50000/mm3. Staphylococcus aureus is the most commonly cultured organism. Recent systematic reviews have identified the most effective drainage techniques, including needle aspiration, arthroscopy and arthrotomy, depending on the affected joint. After the drainage procedure it is important to monitor the clinical and laboratory outcomes. Additional drainage procedures may be necessary in select cases.

A systematic review of the optimal drainage technique for septic hip arthritis in children.

INTRODUCTION: The hip is one of the most commonly affected joints in paediatric septic arthritis. Drainage can be performed using arthrocentesis (articular needle aspiration), arthroscopy or arthrotomy. The objective of this systematic review was to identify the most effective drainage technique for septic hip arthritis in the paediatric population. MATERIALS AND METHODS: The electronic MEDLINE, EMBASE and Cochrane databases were systematically searched for original articles that reported outcomes of arthrocentesis, arthroscopy or arthrotomy for septic arthritis of the paediatric hip. Outcome parameters were additional drainage procedures, clinical outcomes and radiological sequelae. The quality of each of the included studies was assessed with the Methodological Index for Non-randomized Studies (MINORS) score. RESULTS: Out of 2428 articles, 19 studies with a total of 406 hip joints were included in the systematic review. Additional arthroscopy or arthrotomy was performed in 15% of the hips treated with arthrocentesis, in 14% after arthroscopy and in 3% after arthrotomy. Inferior clinical outcomes and more radiological sequelae were seen in patients treated with an arthrotomy. A meta-analysis could not be performed due to the diversity and low quality of the studies (MINORS median 4 [range 2-15]). CONCLUSIONS: This systematic review gives a comprehensive overview of the available literature on treatment for septic hip arthritis in children. Arthrocentesis and arthroscopic procedures may have a higher risk of additional drainage procedures in comparison with arthrotomy. However, arthrotomy might be associated with inferior outcomes in the longer term. The included studies are diverse and the scientific quality is generally low.

Joint Distraction for Thumb Carpometacarpal Osteoarthritis: 2-Year Follow-up Results of 20 Patients.

Background Joint distraction is a fairly new treatment for patients with symptomatic thumb carpometacarpal osteoarthritis (CMC1 OA). A previous pilot study of five patients showed that CMC1 joint distraction is technically feasible. The current study presents the results of CMC1 joint distraction in 20 patients with a 2-year follow-up period. Purposes The primary study aim was to assess if patients with CMC1 OA have better physical function and less pain 2 years after CMC1 joint distraction. Second, we assessed the number of patients who achieved a minimal clinically important difference (MCID) in patient-reported outcome measures at each follow-up time point. Furthermore, this study sought differences on magnetic resonance imaging (MRI) of the CMC1 joint before and after distraction. Adverse events were noted and reported. Methods Twenty patients (median age of 54 years) with symptomatic CMC1 OA and an established indication for a trapeziectomy were enrolled. An external distractor device was placed over the CMC1 joint and left in situ for 8 weeks. Disabilities of the Arm, Shoulder, and Hand (DASH) score, Michigan Hand Outcome Questionnaire (MHQ), visual analogue scale (VAS), and grip strength were recorded preoperatively and at 3, 6, 12, and 24 months postoperatively. Results Two years after joint distraction, physical function and pain scores had improved significantly compared with baseline: DASH from 48 to 17, MHQ from 56 to 83, and VAS for pain from 50 to 18 mm. Fourteen of 19 patients (74%) reached an MCID in DASH and MHQ scores. One patient was not satisfied with treatment outcome and chose to proceed with a trapeziectomy 14 months after initial distraction therapy. Conclusions This study demonstrates that CMC1 joint distraction can postpone more invasive surgical interventions (e.g., trapeziectomy) for at least 2 years. Larger comparative studies are needed to assess the value of CMC1 joint distraction in the treatment of CMC1 OA. Level of Evidence This is a Level IV, prospective case series study.

Aspiration or arthrotomy for paediatric septic arthritis of the shoulder and elbow: a systematic review.

Upper extremity arthritis in children can be treated with joint aspiration, arthroscopy or arthrotomy, followed by antibiotics. The literature seems inconclusive with respect to the optimal drainage technique. Therefore, the objective of this systematic review was to identify the most effective drainage technique for septic arthritis of the upper extremity in children.Two independent investigators systematically searched the electronic MEDLINE, EMBASE and Cochrane databases for original articles that reported outcomes of aspiration, arthroscopy or arthrotomy for septic arthritis of the paediatric shoulder or elbow. Outcome parameters were clinical improvement, need for repetitive surgery or drainage, and complications.Out of 2428 articles, seven studies with a total of 171 patients treated by aspiration or arthrotomy were included in the systematic review. Five studies reported on shoulder septic arthritis, one study on elbow septic arthritis, and one study on both joints. All studies were retrospective, except for one randomized prospective study. No difference was found between type of treatment and radiological or clinical outcomes. Aspiration of the shoulder or elbow joint required an additional procedure in 44% of patients, while arthrotomy required 12% additional procedures.Conclusion: Both aspiration and arthrotomy can achieve good clinical results in children with septic arthritis of the shoulder or elbow joint. However, the scientific quality of the included studies is low. It seems that the first procedure can be aspiration and washout and start of intravenous antibiotics, knowing that aspiration may have a higher risk of additional drainage procedures.

Arthrocentesis, arthroscopy or arthrotomy for septic knee arthritis in children: a systematic review.

PURPOSE: Septic knee arthritis in children can be treated by arthrocentesis (articular needle aspiration) with or without irrigation, arthroscopy or arthrotomy followed by antibiotics. The objective of this systematic review was to identify the most effective drainage technique for septic arthritis of the knee in children. METHODS: The electronic PubMed, Embase and Cochrane databases were systematically searched for original articles that reported outcomes of arthrocentesis, arthroscopy or arthrotomy for septic arthritis of the knee. The quality of all included studies was assessed with the Methodological Index for Non-Randomized Studies (MINORS) criteria. This systematic review was performed and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Out of 2428 articles, 11 studies with a total of 279 knees were included in the systematic review. The quality of evidence was low (MINORS median 4 (2 to 7)). A meta-analysis could not be performed because of the diversity and low quality of the studies. In septic knee arthritis, additional drainage procedures were needed in 54 of 156 (35%) knees after arthrocentesis, in four of 96 (4%) after arthroscopy and in two of 12 (17%) after arthrotomy. CONCLUSION: Included studies on treatment strategies for septic arthritis of the knee in children are diverse and the scientific quality is generally low. Knee arthroscopy might have a lower risk of additional drainage procedures as compared with arthrocentesis and arthrotomy, with acceptable clinical outcomes and no radiological sequelae. LEVEL OF EVIDENCE: IV.

Arthroscopic and open debridement in primary elbow osteoarthritis: a systematic review and meta-analysis.

Primary osteoarthritis (OA) of the elbow can cause disabling symptoms of pain, locking, stiffness, and a limitation in the range of motion. There is no consensus regarding the role of open and arthroscopic debridement in the treatment of symptomatic primary elbow OA. The aim of this study is to systematically review the outcome of surgical debridement. A preoperative/postoperative comparison will be made between the two surgical procedures.All studies reporting on debridement as treatment for primary elbow OA with a minimum of one-year follow-up were included. Outcome parameters were functional results, complications, and performance scores.Data were extracted from 21 articles. The arthroscopic group consisted of 286 elbows with a weighted mean follow-up of 40 ± 17 months (range, 16-75). The open group consisted of 300 elbows with a weighted mean follow-up of 55 ± 20 months (range, 19-85). Both procedures showed improvement in Mayo Elbow Performance Score (MEPS), range of motion (ROM) flexion-extension, and ROM pronation-supination. Only in ROM flexion was a statistically significant difference in improvement seen between the groups in favour of the open group. The arthroscopic group showed improvement in pain visual analogue scale (VAS) scores. Nothing could be stated about pain VAS scores in the open group due to a lack of data. In the arthroscopic group 18 complications (6%) were described, in the open group 29 complications (12%).Surgical debridement is an effective treatment for the disabling symptoms of primary elbow OA with an acceptable complication rate.

Joint distraction for thumb carpometacarpal osteoarthritis: a feasibility study with 1-year follow-up.

OBJECTIVE: The purpose of this pilot study was to evaluate the feasibility of joint distraction of the first carpometacarpal (CMC1) joint in patients with CMC1 osteoarthritis (OA). METHODS: An external joint distractor was placed over the CMC1 joint by K-wire fixation in the trapezium and the metacarpal. The joint was distracted 3 mm during surgery. The device was then kept in place for 8 weeks. Disabilities of the Arm, Shoulder, and Hand (DASH) score, Michigan Hand Outcome Questionnaire (MHQ), Visual Analogue Scale (VAS), and grip strength were recorded preoperatively and at set postoperative intervals. RESULTS: Five female patients with an average age of 53 years (range = 41-61) were included. One year postoperatively, average DASH, MHQ, and VAS scores improved compared to preoperative values; DASH 53 to 27, MHQ 48 to 76, and VAS pain 48 to 14. There were no technical problems associated with the device. One patient had a local pin site infection treated successfully with oral antibiotics. CONCLUSIONS: This study concludes that joint distraction of the osteoarthritic CMC1 joint is technically feasible. In this small, prospective pilot study the majority of the results were favourable during short-term follow-up.

Retrospective Study of a Series of 20 Ivory Prostheses in the Treatment of Trapeziometacarpal Osteoarthritis.

Background Many surgical treatment options for osteoarthritis (OA) of the trapeziometacarpal (TMC) joint exist. However, no procedure has been proven superior. Good results have been described for TMC joint replacement. Purpose To analyze the results of the Ivory prosthesis in the treatment of symptomatic TMC OA. Patients and Methods A retrospective single-center follow-up study was performed. Visual analogue scale (VAS) for pain, Disabilities of the Arm, Shoulder and Hand (DASH) score, Michigan Hand Outcomes Questionnaire (MHQ), active range of motion, strength, and radiological outcomes were assessed and analyzed. Differences between the operated and nonoperated hand were analyzed using paired t-tests. Twenty patients were included with a mean follow-up duration of 37.0 months. Results Patients experienced minimal pain with a mean VAS pain score of 1.9. DASH and MHQ scores indicated mild to moderate impairments. Eighty-five percent of patients assessed the operation excellent or good. Significant differences were found in measurements of extension and palmar thumb abduction in favor of the contralateral hand. No significant differences in strength between both hands were found. Two patients had a dislocation of the prosthesis; one patient required open reduction and tightening of the joint capsule. The other dislocation was treated with trapeziectomy and interposition of a fascia lata allograft. One patient had a collapse of the trapezium requiring a revision procedure. Conclusion Ivory prosthesis TMC arthroplasty can achieve good results in patients with symptomatic isolated TMC OA. In this series, however, revision surgery was required in 3 of 20 cases.

Partial trapeziectomy and interposition of fascia lata allograft in the operative treatment of thumb base osteoarthritis.

AIM: The purpose of this retrospective cohort study was to evaluate the results of fascia lata allograft interposition after partial trapeziectomy in patients with symptomatic first carpometacarpal joint osteoarthritis. METHODS AND RESULTS: Twenty-one patients (22 thumbs) with Eaton-Glickel stage II or III first carpometacarpal joint osteoarthritis were included. After a mean follow-up duration of 70.2 months, most patients experienced minimal pain. The operation was graded excellent or good by 15 patients (15 hands). Active range of motion and strength measurements were comparable to the contralateral hand, except for extension, which was slightly better in the contralateral hand. The mean radiologically measured difference pre- and postoperatively in distance between distal part of the trapezium and base of the metacarpal was 2.7 mm. Two patients had reoperations in the first year after the initial operation because of ongoing pain. CONCLUSION: Partial trapeziectomy with interposition of fascia lata allograft in patients with symptomatic first carpometacarpal joint osteoarthritis can achieve reasonable results. It may be considered a reliable operative treatment option in patients with first carpometacarpal joint osteoarthritis.

The result of transmuscular versus transosseous repair of the posterior capsule on early dislocations in primary hip arthroplasty.

PURPOSE: Dislocation is a concerning complication of the posterolateral approach for total hip arthroplasty (THA). Use of a larger size femoral head and a correct repair of the posterior structures can reduce the risk on dislocation of the hip prosthesis. In this study we investigated if there was a difference in dislocation rate between transmuscular and transosseous repair of the posterior soft tissues with use of 36 mm heads. METHODS: A power analysis showed that with a standardised effect size of 0.3 and p-value of 0.05, each group should include at least 174 patients. A total of 465 consecutive primary THAs with a posterolateral approach were performed in patients with primary osteoarthritis by 3 orthopaedic surgeons. There were 246 patients operated using transmuscular repair, the other 219 by using transosseous repair. All patients were given the same prostheses. RESULTS: Dislocation rate was 1.7% in all patients with at least 1 year follow-up. No significant difference was found in dislocation between both reconstruction techniques. Clinical outcome scores were comparable between the groups. CONCLUSIONS: Transosseous and transmuscular repair were equally effective techniques in closing the posterior soft tissues after THA through the posterolateral approach, without difference in dislocation rate or complication rate.

Conservative treatment of thumb base osteoarthritis: a systematic review.

PURPOSE: To provide a systematic review of randomized controlled trials regarding the conservative treatment of thumb base osteoarthritis (OA). METHODS: A systematic literature search was conducted in the electronic bibliographic databases Medline (Pubmed) and Embase (both starting year to May 2014) using predetermined criteria for studies on nonoperative treatment of thumb base OA. RESULTS: Twenty-three articles fulfilled our inclusion criteria. Systematic evaluation demonstrated the following: (1) Hand therapy can possibly reduce pain. However, owing to the lack of good-quality (randomized controlled) trials with sufficient follow-up time, no proper conclusions can be drawn. (2) Although both steroid and hyaluronate intra-articular injections can provide pain relief, most authors conclude that injection of hyaluronate is more effective. Follow-up is rather short with a maximum of 12 months in 1 study. Furthermore, study comparison is hampered by heterogeneity of study design and outcome parameters. (3) The use of orthoses reduces pain without effect on function, strength, or dexterity. Included studies used various types of orthoses. Follow-up times varied (2 wk-7 y). (4) There is no justification for the use of transdermal steroid delivery. (5) There is insufficient evidence justifying the use of leech therapy. (6) There are no high-level evidence studies specifically evaluating the effect of analgesics and patient education in joint protection in patients with thumb base OA. CONCLUSIONS: There are only a few high-quality studies addressing the conservative treatment of trapeziometacarpal OA. Available evidence suggests only some effect of orthoses and intra-articular hyaluronate or steroid injections.

Foreign body reaction associated with polyethylene mesh interposition used for treatment of trapeziometacarpal osteoarthritis: report of 8 cases.

PURPOSE: To report the incidence of foreign body reactions associated with placement of a polyethylene mesh implant in patients treated with trapiezectomy for trapeziometacarpal osteoarthritis. METHODS: Between November 2008 and September 2012, 70 hands in 66 adults with stage IV trapeziometacarpal osteoarthritis had a trapiezectomy with interposition of a spacer made of polyethylene terephthalate mesh (Anchois Ligastic, Orthomed SA, St Jeannet, France). Out of these 70 implants, 8 implants (11%) in 8 patients (mean age, 60 y; range, 49-75 y) were removed because of persistent swelling, synovitis, and pain. RESULTS: The mean interval between primary and revision surgery was 14 (range, 5-27) months. Histological analysis in all cases showed a foreign body giant cell reaction. Two hands showed bone resorption or carpal bone cysts similar to silicone particle synovitis. The cysts resolved after implant removal and bone grafting. CONCLUSIONS: In the light of these results and the available literature, we recommend not using this material for interposition in the treatment of osteoarthritis of the trapeziometacarpal joint. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

The value of 3.0-tesla MRI in diagnosing scapholunate ligament injury.

Objective To determine the sensitivity and specificity of 3.0-tesla (T) magnetic resonance imaging (MRI) and a dedicated hand coil in diagnosing scapholunate ligament (SLL) injury compared with intraoperative findings. Methods From January 2006 until September 2010, 3.0-T MRI scans were performed on 38 wrists (37 patients) with clinically unclear but suspected lesions of the SLL. These scans were evaluated by two experienced radiologists. Radiological findings were compared with intraoperative findings during arthrotomy. Sensitivity, specificity, accuracy, and positive and negative predictive value were calculated. Results An SLL lesion was identified during arthrotomy in 37 wrists. The first radiologist identified an SLL lesion on MRI in 26 wrists, all of which were confirmed intraoperatively. The second radiologist identified SLL lesions in 31 patients; however, intraoperatively it was found that there was no lesion of the ligament in one patient. Sensitivity ranged from 70 to 81% with a specificity of 100% and a positive predictive value of 97 to 100%. Accuracy measured 71 to 79%. Conclusions 3.0-T MRI of the wrist is moderately sensitive and very specific for detection of SLL lesions. However, if there is a high clinical suspicion of an SLL rupture, a 3.0-T MRI does not often have an additional value. Level of Evidence Diagnostic, level II.

High complication rate in the early experience of minimally invasive total hip arthroplasty by the direct anterior approach.

BACKGROUND AND PURPOSE: There is growing interest in minimally invasive surgery techniques in total hip arthroplasty (THA). In this study, we investigated the learning curve and the early complications of the direct anterior approach in hip replacement. METHODS: In the period January through December 2010, THA was performed in 46 patients for primary osteoarthritis, using the direct anterior approach. These cases were compared to a matched cohort of 46 patients who were operated on with a conventional posterolateral approach. All patients were followed for at least 1 year. RESULTS: Operating time was almost twice as long and mean blood loss was almost twice as much in the group with anterior approach. No learning effect was observed in this group regarding operating time or blood loss. Radiographic evaluation showed adequate placement of the implants in both groups. The early complication rate was higher in the anterior approach group. Mean time of hospital stay and functional outcome (with Harris hip score and Oxford hip score) were similar in both groups at the 1-year follow-up. INTERPRETATION: The direct anterior approach is a difficult technique, but adequate hip placement was achieved radiographically. Early results showed no improvement in functional outcome compared to the posterolateral approach, but there was a higher early complication rate. We did not observe any learning effect after 46 patients.

An alternative suspension technique after trapeziectomy for advanced thumb carpometacarpal osteoarthritis.

Osteoarthritis of the first carpometacarpal joint is often treated by (partial) trapeziectomy and tendon interposition or suspension arthroplasty procedures. In this article, an alternative suspension technique, using 2 osseous tunnels (through the first and second metacarpal) and a flexor carpi radialis tendon strip, is described.
