Arthroscopic resection arthroplasty for malunited intra-articular distal radius fractures.

PURPOSE: Cartilage damage of the carpals is a contraindication for corrective osteotomy of the malunited intra-articular distal radius fracture and typically is treated in the symptomatic patient with a salvage procedure. Here, we present our experience and early results with arthroscopic resection arthroplasty of the radiocarpal joint. METHODS: We treated 10 patients (age, 17-68 y; average, 53 y) who had intra-articular malunion of the distal radius with mirror erosion on the carpals. The original fracture occurred 4 to 36 months (average, 9 mo) before our intervention. We performed arthroscopic arthrolysis and resected the offending portion of the radial malunited fragment, eliminating the stepoff and creating a smoother joint surface. Range of motion was started immediately after the operation, except in 2 patients. RESULTS: The locations of the malunions were evenly distributed between the scaphoid fossa, the lunate fossa, or both. Stepoffs varied from 2 to 6 mm. We resected up to 60% of the entire radial articular surface to obtain a smooth surface (average, 28%; range, 20% to 60%). All patients reported immediate relief of pain and improvement in motion (particularly extension). At the latest follow-up (average, 28 mo; range, 13-42 mo), average extension improved from 24° to 54°, average grip strength improved from 47% to 89% of the contralateral wrist, average Disabilities of the Arm, Shoulder, and Hand score improved from 74 to 18, and average Patient-Rated Wrist Hand Evaluation score improved from 79 to 15. CONCLUSIONS: The aim of the operation was to relieve patients' pain by providing a smooth, although fibrocartilaginous, surface for the carpus to glide on the radius. The follow-up was short and the results may be short-lived. However, for the younger patient, it may provide a temporary alternative to partial wrist arthrodesis with minimal morbidity, and for the less demanding patients, it may be a definitive procedure.

Early experience with (dry) arthroscopic 4-corner arthrodesis: from a 4-hour operation to a tourniquet time.

PURPOSE: Scaphoidectomy and 4-corner arthrodesis (4CA) is an effective procedure for treating several degenerative conditions of the wrist. Recently, the arthroscopic approach to this operation was described. Although it is conceptually appealing, certain aspects make its application difficult. We present our technique for dry arthroscopic scaphoidectomy and 4CA, which reduces the operative time to less than 2 hours. METHODS: Four consecutive patients underwent scaphoidectomy and 4CA. In each case, we performed the operation with a dry arthroscopic technique using cannulated screws for rigid fixation. We performed bone grafting from the distal radius in 2 patients and from the scaphoid itself in the other two. The relevant operative details are the use of a scapholunate portal, the resection of the scaphoid with a pituitary rongeur, and the placement of bone graft in a dry arthroscopic environment. Range of motion exercises are started 2 to 3 weeks after the operation. RESULTS: The first operation took 4 hours. The last 2 were completed in 1 hour 45 minutes and 1 hour 55 minutes, respectively. No complications occurred. No operations were converted to an open procedure. CONCLUSIONS: Although the operation has a steep learning curve, it is conceptually appealing. It is too early to prove that the arthroscopic procedure has better results than the open 4CA; nevertheless, in our opinion it represents the future of wrist surgery.

Reconstruction of the ulnar head with a vascularized second metatarsal head: case report.

A case of a young patient with avascular necrosis of the ulnar head following a severely displaced ulnar head fracture is presented. Treatment included debridement of the entire ulnar head, leaving the ulnar styloid, sigmoid notch, triangular fibrocartilage, and both distal radioulnar ligaments intact. The head of the ulna was reconstructed by transferring a vascularized second metatarsal head. At 4-year follow-up, the patient had a pain-free wrist with 45° active pronation and 65° supination. He resumed working without limitations as a manual laborer. We conclude that ulnar head reconstruction with a vascularized second metatarsal head is worthwhile in the setting of an unreconstructable traumatic defect, particularly when the sigmoid notch and distal radioulnar ligaments are preserved.

Sigmoid notch reconstruction and limited carpal arthrodesis for a severely comminuted distal radius malunion: case report.

We present the case of a young patient with a severely comminuted, malunited, intra-articular distal radius fracture and complete disruption of the sigmoid notch. We reconstructed the malunited distal radioulnar joint by osteotomy and repositioning the displaced sigmoid notch fragments through a combined dorsal and volar approach. At the same time, we carried out a radioscapholunate arthrodesis with distal scaphoid excision. We used a free vascularized corticoperiosteal flap from the medial femoral condyle to span the massive bone defect in the radius to obtain union. At the 2.5-year follow-up, the patient had essentially normal function of the distal radioulnar joint (painless, with 85° of active pronation and 75° of supination). He resumed work as a bricklayer without limitations. We conclude that sigmoid notch reconstruction by osteotomy is worthwhile in the setting of malunited distal radius whether or not the radiocarpal joint is reconstructable.

An all-inside technique for arthroscopic suturing of the volar scapholunate ligament.

Repair of the volar scapholunate ligament has not been performed arthroscopically. We present an all-inside technique that presents closure of the anterior scapholunate interval. A Tuohy needle and a resorbable suture are all that is required.

Informe sobre el trasplante de 250 dedos del pie a la mano consecutivos. Indicaciones, resultados, fracasos y nuevas aplicaciones / Report on 250 consecutive toe to finger transplants. Indications, results, failures, and new applicactions

Propósito. Las transferencias de dedos del pie constituyen un arma fundamental en la rehabilitación de las lesiones de mano. Sin embargo, no gozan de mucha popularidad dada la posibilidad de fracaso y por las hipotéticas secuelas en la zona donante. Presentamos nuestra experiencia clínica, haciendo especial hincapié en las complicaciones y las nuevas aplicaciones. Material y métodos. En el periodo febrero de 1995 - enero de 2010 hemos realizado 250 transferencias de dedos del pie para amputaciones de todos o parte de los dedos. En las amputaciones de todos los dedos (23 casos) se trasplantaron el hallux de un pie y el 2.° y 3.er dedos del pie contralateral para lograr una pinza trípode. El resto de los casos corresponden a amputaciones multidigitales, simples o parciales de dedos, siendo 69 casos pulgares y el resto, dedos trifalángicos. Resultados. La tasa de reintervención por isquemia aguda fue del 16% (10% intraoperatoria), con una supervivencia final del 98,8% (3 fracasos) tras la revisión quirúrgica. No hubo ninguna necrosis parcial. Respecto a la zona donante, un paciente fue intervenido por presentar un neuroma; el resto no refirió ningún tipo de molestias a la marcha, en el seguimiento a largo plazo. Conclusiones. En nuestra experiencia, las transferencias de dedos del pie son un método seguro en la reconstrucción de lesiones graves de la mano. La secuela del pie es proporcional a la cantidad de dedos que se tomen, y es bien aceptada por el paciente, en especial en las graves lesiones (AU)

Purpose. Toe-to-hand transfers are an essential part of hand rehabilitation after loss of a finger. Despite this, the likelihood of failure and the hypothetical morbidity in the donor area, made this procedure not very popular among surgeons. The purpose of this paper is to present our clinical experience, highlighting the pitfalls and the new indications. Material and methods. Between February 1995-January 2010 we performed 250 toe-to-hand transfers for finger amputations. In metacarpal hands (23 cases) we transferred the hallux from one foot and the 2nd and 3rd from the other, to achieve a three-fingered (tripod) grasp. The rest of the patients had multi-digital, simple or partial amputations. In 69 the thumb was reconstructed and the rest of transfers were for finger reconstructions. Results. Re-operation rate due to acute ischaemia was 16% (10% intraoperative) and the overall success rate was 98.8% (3 failures). There was no partial necrosis in any case. Regarding the donor side, one patient was operated on due to a painful neuroma; the rest did not have complaints in the donor area. Conclusions. In our experience toe-to hand transfers are a safe and reliable method to rehabilitate severe hand injuries. Donor site morbidity is directly related to the number of toes harvested, and is well-tolerated by the patients, especially in severe injuries (AU)

Arthroscopically guided osteotomy for management of intra-articular distal radius malunions.

PURPOSE: A malunion with a step-off of 1 mm or more after an intra-articular distal radius fracture may cause pain and arthritic changes at midterm follow-up. We present our technique for treating intra-articular distal radius malunions by carrying out an osteotomy from inside the joint outward under arthroscopic guidance using the dry arthroscopy technique, with emphasis on the clinical and radiologic outcomes. METHODS: We performed surgery on 11 patients for intra-articular malunion of the distal radius 1 to 5 months after the injury. Preoperative step-offs ranged from 2 to 5 mm (average, 2.5 mm) on plain radiographs. Original fracture patterns involved 1 radial styloid fracture, 1 radiocarpal fracture-dislocation, and 9 comminuted intra-articular fractures. In 5 cases an anterior-ulnar or radial styloid fragment was repositioned. In the rest, more than 1 fragment (up to 3) was osteotomized. In 1 patient the articular osteotomy was combined with an ulnar shortening osteotomy. RESULTS: Follow-up ranged from 12 to 48 months. Step-offs were reduced in most cases to 0 mm; however, localized gaps (<2 mm) and cartilage defects were commonly seen intraoperatively because the fragments did not accurately fit. According to the Gartland and Werley score, there were 4 excellent and 7 good results (mean score of 2.8). The Modified Green and O'Brien system achieved a mean score of 83, with 3 excellent, 5 good, and 3 fair results. One patient showed radiolunate narrowing on follow-up radiographs. CONCLUSIONS: Arthroscopically assisted osteotomy permits direct visualization of the osteotomy site with good midterm clinical and radiologic outcomes. The technique can be used in irregularly defined fragments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
