Functional outcome of arthroscopic assisted fixation of distal radius fractures

Background:

Many studies in literature have supported the role of wrist arthroscopy as an adjunct to the stable fixation of unstable intraarticular distal radial fractures. This article focuses on the surgical technique, indications, advantages, and results using wrist arthroscopy to assess articular reduction and evaluates the treatment of carpal ligament injuries and triangular fibrocartilage complex (TFCC) injuries in conjunction with the stable fixation of distal radial fractures.

Materials and Methods:

We retrospectively evaluated 27 patients (16 males and 11 females), who underwent stable fixation of intraarticular distal radial fractures with arthroscopic evaluation of the articular reduction and repair of associated carpal injuries. As per the AO classification, they were 9 C 1, 12 C2, 2 C3, 3 B 1, and 1 B2 fractures. The final results were evaluated by modified Mayo wrist scoring system. The average age was 41 years (range: 18-68 years). The average followup was of 26 months (range 24-52 months).

Results:

Five patients needed modification of the reduction and fixation after arthroscopic joint evaluation. Associated ligament lesions found during the wrist arthroscopy were TFCC tears (n=17), scapholunate ligament injury (n=8), and luno-triquetral ligament injury (n=1). Five patients had combined injuries i.e. included TFCC tear, scapholunate and/or lunotriquetral ligament tear. There were 20 excellent, 3 good, and 4 fair results using this score.

Conclusion:

The radiocarpal and mid carpal arthroscopy is a useful adjunct to stable fixation of distal radial fractures.     

Laparoscopic distal pancreatectomy is as safe and feasible as open procedure: a meta-analysis

AIM: To evaluate the feasibility and safety of laparoscopic distal pancreatectomy (LDP) compared with open distal pancreatectomy (ODP).METHODS: Meta-analysis was performed using the databases, including PubMed, the Cochrane Central Register of Controlled Trials, Web of Science and BIOSIS Previews. Articles should contain quantitative data of the comparison of LDP and ODP. Each article was reviewed by two authors. Indices of operative time, spleen-preserving rate, time to fluid intake, ratio of malignant tumors, postoperative hospital stay, incidence rate of pancreatic fistula and overall morbidity rate were analyzed.RESULTS: Nine articles with 1341 patients who underwent pancreatectomy met the inclusion criteria. LDP was performed in 501 (37.4%) patients, while ODP was performed in 840 (62.6%) patients. There were significant differences in the operative time, time to fluid intake, postoperative hospital stay and spleen-preserving rate between LDP and ODP. There was no difference between the two groups in pancreatic fistula rate [random effects model, risk ratio (RR) 0.996 (0.663, 1.494), P = 0.983, I² = 28.4%] and overall morbidity rate [random effects model, RR 0.81 (0.596, 1.101), P = 0.178, I² = 55.6%].CONCLUSION: LDP has the advantages of shorter hospital stay and operative time, more rapid recovery and higher spleen-preserving rate as compared with ODP.     

Symptomatic change and gastrointestinal quality of life after pancreatectomy

Background

Pancreatectomy affects gastrointestinal (GI) symptoms. Our purpose was to assess the quality of life of pancreatectomy patients in relation to GI function.

Methods

Pancreatectomy patients were asked qualitative, open-ended questions about symptoms. They also completed the Gastrointestinal Symptom Rating Scale (GSRS) for reflux syndrome, acute pain syndrome, indigestion syndrome, diarrhoea syndrome and constipation syndrome.

Results

A total of 52 patients participated. Of these, 69% reported an improvement and 31% reported no change in preoperative symptoms. No patients reported a worsening of symptoms. Half (50%) of the patients experienced new, different symptoms. Median GSRS scores were 0 for reflux syndrome [interquartile range (IQR): 0–1.0], 0 for acute pain syndrome (IQR: 0–1.0), 2.0 for indigestion syndrome (IQR: 1.0–4.0), 2.0 for diarrhoea syndrome (IQR: 0.5–4.5), and 0 for constipation syndrome (IQR: 0–1.0). Whipple operation patients scored higher on the reflux syndrome (0.5 vs. 0; P = 0.08) and indigestion syndrome (3.5 vs. 1.5; P = 0.06) domains. A total of 68% of Whipple operation patients experienced new symptoms, compared with 32% of patients who had undergone other types of pancreatectomy (P = 0.002). Scores of patients who had undergone surgery <2 years and >2 years earlier, respectively, did not differ.

Conclusions

Patients who underwent pancreatectomy frequently experienced an improvement in preoperative symptoms, but also experienced new postoperative symptoms. This was more common after Whipple operations. However, these symptoms were relatively mild in severity. These mild symptoms seem to persist over time.     

Bösch technique for hallux valgus surgery in a tropical setting

ObjectivesTo evaluate the early clinical and radiological results using the Bösch technique to treat hallux valgus.Material and methodsWe reviewed retrospectively four patients with 6 feet undergoing the Bösch technique for mild and moderate hallux valgus from 2009 to 2012 with an average follow-up of 10.8 months. All patients complained of pain around the first metatarsophalangeal joint. They had cosmetic concerns, and difficulty in wearing shoes. At final follow-up patients were asked about the improvement of pain, cosmetic appearance of the foot, problems with wearing shoes, the ability to walk, and their satisfaction with the operation. Complications encountered were also recorded. The radiographic evaluation considered osteotomy site union, the hallux valgus angle, and the intermetatarsal angle.ResultsAll patients complained of mild or no pain. They had a satisfactory cosmetic result, wore normal shoes without problems with no limitation of walking ability. They were satisfied with the procedure. One case of superficial infection was noticed. All osteotomies healed primarily within three months. The average hallux valgus angle improved from 32.7° preoperatively to 14.8° at final follow-up and the average intermetatarsal angle from 17.5° to 9.2°.ConclusionThe Bösch technique is a cost effective procedure that yields good clinical and radiological results while correcting mild and moderate symptomatic hallux valgus with reduced risk of surgery related complications.     

Intramedullary nailing of humeral diaphyseal fractures. Is distal locking really necessary?

Purpose:

Distal interlocking is regarded as an inherent part of the antegrade humeral nailing technique, but it exposes both the patient and surgeon to radiation, is time consuming, and has a potential risk of damaging neurovascular structures. We have presented our technique of diaphyseal humeral nailing without any distal interlocking in this paper.

Materials and Methods:

We have presented a series of 64 consecutive patients (33 male and 31 female, mean age: 41.5 years) with humeral shaft fractures treated with antegrade rigid intramedullary nailing without distal interlocking following a strict intra and postoperative protocol. According to the AO classification, there were 36 type A fractures, 22 type B, and 6 type C. Nails were inserted unreamed or by using limited proximal reaming and they were fitted as snuggly as possible into the medullary canal. After impaction of the nail into the fossa, we carefully tested rotational stability of fixation by checking any potential external rotation when the arm was slightly turned externally and left to the gravity forces. We were ready to add distal screws, but that was not required in these cases. Follow-up assessment included fracture union, complications and failures, and the final clinical outcome at minimum 2-year follow-up using the parameters of the constant score.

Results:

All fractures, except two, united between the 4^th and 5^th postoperative month. In one case, nail was exchanged with plate, and, in another, a larger nail was used at a second surgery. Shoulder function according to constant score, at a minimum of 2-year follow-up, was excellent or very good in 93.7% of the patients.

Conclusions:

Provided that some technical issues are followed, the method reduces intraoperative time and radiation exposure and avoids potential damage to neurovascular structures.
