3. 변형에 따른 기능적 장애 및 환자 요소
4. 외상 외 원인에 의한 변형
![]() | Fig. 2.Pseudo boutonniere deformity. (A) A 36-year-old male patients presented proximal interphalangeal joint flexion contracture on left 3rd and 4th finger 3 months after hyperextension injury in affected finger joint. The plain X-ray presented volar small bony fragments marked with red circles (B) and the finger distal interphalangeal joint flexion was intact (C). |
![]() | Fig. 3.Boutonniere deformity in Dupuytren contracture disease. (A) A 65-year-old male patient presenting severe Dupuytren contracture on both hand. (B, C) The left 5th finger is also accompanied by boutonniere deformity. (D, E) With aggressive palmar fasciectomy and dorsal terminal tendon tenotomy, the deformity could be corrected. |

단추구멍 변형의 치료
1. 수술적 치료의 적응증
2. 보존적 치료
3. 수술적 치료
1) 종말 건 절제술
2) 측부대 수술법
![]() | Fig. 4.Lateral band dorsal translocation and sutured together. (A) A 61-year-old female patient presented over 90° extension lag in left 3rd finger. (B, C) With dorsal approach, the central tendon almost lost function and bilateral lateral bands were released and suture together at the center of middle phalanx. (D, E) The patient recovered 0° of extension in proximal interphalangeal joint but also presented distal interphalangeal joint flexion deficit. |
3) 중앙 건 수술법
![]() | Fig. 5.Central slip surgery. (A, B) A 35-year-old man with a 40° extensor lag of the proximal interphalangeal (PIP) joint and 20° hyperextension of distal interphalangeal joint after 10 months of initial tendon repair surgery at outer hospital in left 5th finger. (C) With a lazy S-shaped incision over the PIP joint, the elongated scar tissue is identified within the underlying joint capsule. (D) The bilateral sides of the central tendon are incised and released for advancement. (E) The proper length of scar tissue preventing the PIP full extension is resected, including the underlying joint capsule. (F) The volar plate and collateral ligament were release through exposed joint. (G, H) The proximal stump is advanced and the end repair between the distal stump containing the joint capsule using 4-strand core sutures at 0° PIP extension is performed. An additional Mitek Micro QuickAnchor (DePuy Mitek Inc., Raynham, MA, USA) is inserted and sutured to the proximal stump to enhance suture stability. (I, J) At the final clinical follow-up, the range of motion is recorded. |
4) 건 이전술 혹은 건 이식술
5) 단계적 신전 재조정술(Curtis procedure)
6) 관절 고정술
![]() | Fig. 6.Arthrodesis of proximal interphalangeal joint. (A, B) A-65-year old male patient with severe boutonniere deformity with fixed 100° proximal interphalangeal joint flexion contracture with coronal deformation in left 3rd finger. (C-F) The arthrodesis using transosseous two wirings was performed. |
